ARCHIPELAGIC SEA LANES PASSAGE AND MARITIME SECURITY IN ARCHIPELAGIC SOUTHEAST ASIA

ARCHIPELAGIC SEA LANES PASSAGE
AND MARITIME SECURITY
IN ARCHIPELAGIC SOUTHEAST ASIA

ABSTRACT
Title of Write my thesis – Dissertation: Archipelagic Sea Lanes Passage and Maritime Security
in Archipelagic Southeast Asia
Degree: Master of Science
This dissertation examines the regimes of archipelagic waters and archipelagic
sea lanes passage in the context of the two primary proponents of the archipelagic
principle in the United Nations Convention on the Law of the Sea, in light of new
developments in maritime security.
The assessment undertaken in this dissertation deals with the unprecedented
efforts of the Philippines and Indonesia to persuade the international community to
recognize the archipelagic concept, that a group of islands and the waters around,
between and connecting the islands belong to one state should be treated as one single
entity for the purpose of delimiting the maritime zone to achieve prosperity and
development free from external pressure. In order to uphold the traditional freedom of
navigation of the international community in seeming opposition to the concept, the
right of archipelagic sea lanes passage through archipelagic waters was granted to
foreign vessels. This concession was given for purposes of reconciling the conflicting
interests in a manner acceptable to all concerned.
Chapter IV highlights the experience of Indonesia, as the first archipelagic state
to designate archipelagic sea lanes passage while Chapter V looks at the concerns of the
Philippines with regard to the issue of designating such sea lanes.
The concluding chapters contain an analysis of the factors influencing the
designation and the exercise of the right of archipelagic sea lanes passage, and an
iv
assessment of whether the compromise results in a balance. Relevant recommendations
are made with regard to Indonesia and the Philippines.

CHAPTER I
INTRODUCTION
One of the oldest and most recognized principles governing ocean space is
freedom of the sea enshrined in the chapter ‘De Mare Liberum’ of Hugo Grotius’s ‘De
Iure Praedae’.1
The principle upholds the free use of the sea for commercial purposes
and at the same time rejects the claim of exclusive use and possible establishment of
sovereignty over parts of the sea.2
It overshadowed national interests in coastal fisheries
and most of the extravagant claims to maritime sovereignty were abandoned.3

During post World War II period, Grotius’s approach to freedom of the seas
began to be limited by claims of coastal states to sovereign rights over waters adjacent to
their coast. 4 Claims to historic bays and archipelagic waters were among the few
exceptional cases to this principle.5
The codification of the United Nations Convention
on the Law of the Sea of 10 December 1982 (UNCLOS 1982) gave way to expand the

law of the sea to recent developments concerning the interests of individual groups of
states and the international community as a whole.6

UNCLOS 1982 created a new regime for the sea-bed and the ocean floor and
subsoil thereof, beyond the limits of national jurisdiction; a special regime for
archipelagic waters was introduced and increasingly recognized along with other ground
breaking principles in international law.7
The regimes of archipelagic waters and midocean archipelagos are perhaps some of the most difficult and complex problems in
international law considering that geopolitics, economics and security interests as well
as countless of attendant factors posed a monumental challenge.8

The archipelagic states in Southeast Asia, the Philippines and Indonesia, pressed
the international community for some time to recognize their right to establish a system
of straight baselines around their archipelago.9
The geographical features of these two
states can be described as landmasses connected by waters. Both states regard the waters
landward of territorial sea as extensions of land territory. The seas around, between and
connecting the landmasses need to be governed similarly to land territory. Their primary
consideration for the recognition of the archipelagic principle is the preservation of the
integrity of the archipelago.10 Another concern is directed at the presence in their waters
of ships with special characteristics such as warships, surveillance vessels, unauthorized
fishing vessels and vessels engaged in the carriage of contraband.11 For the reason that
the Philippine and Indonesia lie in the crossroads of the Indian and Pacific Oceans, the
geographical locations of these two major archipelagos constitute a barrier for maritime

movement between the two great oceans.12 Also, most of the major straits in Southeast
Asia pass through the waters of either of these two states.13
Under the archipelagic regime, the traditional high seas freedom of navigation
between islands of the archipelagic state has been replaced by a sui generis legal regime
under archipelagic waters. 14 The establishment of baselines enclosing the entire
archipelago would regard the waters in, between and around the islands and extending
outward from the perimeter boundary line as forming part and parcel of the territory of
these archipelagic states. 15 This very concept was opposed by the international
community particularly by maritime powers that needed unrestricted freedom for their
navies because of the crucial importance of free navigation of submarines to their
interests.16 Their concerns stem from the fundamental concept of freedom of the sea
derived from customary law. The high seas are free and open to the use of all nations
and channels traditionally used for international shipping, where the right of free passage
have been present and exercised long before, should be respected. 17 Further, this
situation poses a threat to international navigation in the waters that would be enclosed
by the straight baselines drawn around the outermost islands of archipelagos.18
In view of the complexity of the problem, a major compromise was made in
favour of inclusive interests, which permitted the right of passage through archipelagic
waters.19 Two rights of passage were granted to third states within the archipelagic

waters: the right of innocent passage and a newly defined right of archipelagic sea lanes
passage.20 Innocent passage is for transit by ships through all other archipelagic waters
except for internal waters of an archipelagic state; whereas archipelagic sea lanes
passage is for transit by ships and aircraft in the designated sea lanes or through routes
normally used for international navigation. 21 The right of innocent passage can be
suspended whenever it is essential for the protection of the security of the archipelagic
state 22 whereas, the right of archipelagic sea lanes passage is a non-suspendable right. 23
It reflects a level of freedom of passage by foreign shipping – with an arguably high seas
character akin to those guaranteed under the regime of straits used for international
navigation. 24 Passage under this regime is concerned with transit and carries no
requirement of innocence.25 It also allows transit in ‘normal mode’, which includes
submerged submarine transit, flight operations by aircraft carriers, and the undertaking
of all usual shipboard activities and security measures.26 Johnson pointed out that this
additional freedom is very significant to military vessels and aircrafts and considered as
one of the principal concessions granted by archipelagic states to third states in the
negotiation process.27 This compromise is intended to create a balance between the
archipelagic states, with regard to their interests to exercise sovereignty over adjoining
waters, and international community as the user states or third states on their desire to

retain historical freedom of the seas. Consequently, the specialized passage regime for
archipelagic sea lanes was codified in Part IV Article 53 of UNCLOS 1982.
Prescott states that “once a coastal state has declared archipelagic status it places
upon itself considerable responsibilities to the international community, perhaps the
greatest of which is the right of archipelagic sea lanes passage for international routes
through the archipelago.”28 Presently, among the claimants of archipelagic status, it is
only Indonesia that has designated archipelagic sea lanes. In 1996 Indonesia submitted a
proposal to the International Maritime Organization (IMO)29 for the adoption of various
sea lanes and air routes covering north-south routes through and over its archipelagic
waters.30 The absence of other routes used for international navigation specifically the
east-west route led to significant international protests from maritime states, including
Australia, the United States, the United Kingdom and Japan. 31 In this regard, the
proposal was regarded only as partial designation and other archipelagic sea lanes will
be required to satisfy the requirements of IMO.32 Also, it leaves the way open for user
states to regard any route used for international navigation as available for archipelagic
sea lanes passage. 33 Although it was held by IMO as a partial designation, it was
subsequently approved on May 1998 and duly entered into force through Indonesian
Government Decree No. 37/2002 dated 22 June 2002.
On the other hand, the Philippines has yet to submit a similar proposal to IMO
although it has already identified the routes where archipelagic sea lanes will be
designated. There are legal issues surrounding the case of the Philippines considering

that it regards the archipelagic waters as internal waters.34 This implies that rights of
innocent passage and archipelagic sea lanes passage may not be recognized in these
waters. It has not also enacted legislation to govern routes used for international
navigation. Be that as it may, its state practice complies with the requirements of
UNCLOS 1982 in terms of allowing passage of foreign vessels through its archipelagic
waters.35
Under UNCLOS 1982, an archipelagic state is not required to designate
archipelagic sea lanes. Should it choose to do so, however, it shall cover all routes used
for international navigation. UNCLOS also provides that if no archipelagic sea lanes are
designated, the right of passage may be exercised through routes normally used for
international navigation. Given that the right of archipelagic sea lanes passage is nonsuspendable under any circumstances, different factors that may affect the designation or
non-designation of these sea lanes, primarily the security of such sea lanes, their
adjacent coasts and waters, and that of the state itself, will be the very focus of this
study.
1.1 Objective and Significance of the Study

The events of September 11 changed the perception of the world to terrorism and
increased the concern of all states with regard to their national security. This is
illustrated by the notion that terrorists can turn ordinary means of transportation into
devastating weapon against wide variety of targets, not only governmental but also
economic lifelines.36 A large percentage of the global economy is facilitated through the

sea which makes shipping and seaborne trade attractive targets for terrorist attacks. This
vulnerability is aggravated by difficulties of enforcement both in port and at sea and
quantities of cargo involved which could be exploited by terrorist to launch an attack on
shipping and port infrastructure that could cause massive economic disruption.37
A significant volume of world trade, particularly those between East Asia and the
rest of the world, passes through the important sea lanes and international routes of
Indonesia and the Philippines. Any maritime threat that would result in the blocking of
straits and international routes would affect the global economy and security of maritime
domain of the archipelagic state. With this development, the maritime security concerns
of these two archipelagos have increased further. For a long period of time, both states
have been facing challenges regarding their respective strategic straits, sea lanes and
other parts of the maritime domain. These challenges are brought about by the threats of
piracy38, armed robbery against ships39 and maritime terrorism along with other crimes
committed through the use of the sea. They also deal with the issue of intrusion of
foreign vessels on their waters as a result of varying interpretation by third states of the
status of archipelagic waters and sea lanes passage. Taking into consideration these
challenges, this dissertation sets the following objectives:
1. Assess the importance of archipelagic sea lanes to the archipelagic states and
the relevance of same to modern day maritime security concerns;

State; (b) any act of voluntary participation in the operation of a ship or of an aircraft with knowledge of

2. Determine whether the right of archipelagic sea lanes passage affect
territorial integrity of the archipelagic states;
3. Evaluate whether the designation is necessary to have a systematic
management of passage for foreign vessels through the archipelagic waters;
4. Examine the so called balance of interests between archipelagic states and the
user states relative to the designation of archipelagic sea lanes;
5. Attempt to recommend measures relevant to the present status of the two
biggest archipelagic states.
1.2 Areas Covered and Research Method Applied
This study will trace the historical development of the archipelagic regime under
UNCLOS 1982 in which the right of archipelagic sea lanes passage was introduced. In
analyzing the rationale for Article 53 (Right of Archipelagic Sea Lanes Passage), it is
necessary to look into state practices, experience of Indonesia in complying Article 53
and the preliminary concerns of the Philippines in holding in abeyance the
implementation of this Article, in the light of the new developments in maritime
security.
The research method applied in this study involves qualitative research in order
to analyze the concept and entire framework of designation of archipelagic sea lanes and
its impact on both the archipelagic states and the user states or third states. Literature
reviewed in this regard included academic books, journal articles, thesis, conference
papers and reports. Also utilized were articles taken from online libraries, relevant texts
from internet websites and newspapers, concerning information that is not readily
available in the WMU library. Interviews to the government officials of either the
Philippines or Indonesia dealing with maritime security issues were not conducted due
to lack of material time.

CHAPTER II
ARCHIPELAGIC STATE REGIME
2.1 Development under United Nations Convention of the Law of the Sea
The great efforts to draft a text on the special status for archipelagos started as
early as the 1920s where the concept had been suggested in different international fora,
such as the International Law Association, the Institute of International Law and the
American Institute of International Law. It was also discussed at the Hague Codification
Conference of 1930 but without conclusive results because technical information on the
matter was inadequate. 40 The question of archipelagos particularly that of coastal
archipelagos was taken up mostly in connection with the question of coastal baseline.41
It was first raised in the Institute de Droit International and was discussed only
in 1927 and 1928 where the following proposals were made by the Fifth Committee. 42
Where a group of islands belong to one coastal State and where
the islands of the periphery of the group are not further apart
from each other than the double breadth of the marginal sea, this
group shall be considered a whole and the extent of the marginal
sea shall be measured from a line drawn between the outermost
parts of the island.
Where archipelagos are concerned, the extent of the marginal
sea shall be measured from the outermost island or islets

40 Supra, footnote 21 at p. 399 41 UN DOALOS Legislative History of Part IV UNCLOS, New York: United Nations 1990 at p. 1 42 Supra, footnote 9 at p. 102
10
provided that the archipelago is composed of islands and islets
not further apart from each other than twice the breadth of the
marginal sea and also provided that the islands and islets nearest
to the coast of the mainland are not situated further out than
twice the breath of the marginal sea.
While the question on archipelagos was also considered by the International Law
Association (ILA), the proposal in this regard did not provide for the permissible
distance between the islands of archipelagos but only states that “the islands thereof
shall be considered as a whole and the extent of the territorial waters laid down in article
4 shall be measured from the islands situated most distant from the centre of the
archipelago”. 43 Similarly, the proposal of American Institute of International Law
published in 1926 did not lay down the maximum distance but only provides that in case
of archipelago, the islands and keys composing it shall be considered as forming a
unit.44 The subject was also not dealt with in the Plenary of The Hague Codification
Conference in 1930 although a proposed article thereof was drafted. 45 Seemingly, after a
considerable debate on the issue of whether the rule that every island can generate a
territorial sea should apply to a group of islands or whether there should be a special
regime to govern it, the subject did not gain support among international bodies dealing
with law of the sea.
It was the decision of the International Court of Justice in the Anglo-Norwegian
Fisheries case, 1951 ICJ Reports 116, 128 and 139 that gave rise to the discussion of a
coastal archipelago concept.
46 It may be recalled that under this case, the United
Kingdom challenged the legality of the lines of delimitation of the Norwegian fisheries
zone which was established based on the July 1935 Decree and was found by the Court

43 Ibid., at p. 103 44 Ibid. 45 Ibid., at p. 104 46 Supra, footnote 41 at p. 41
11
to coincide with the territorial sea of Norway. 47 The ICJ held that the method of straight
baselines employed by Norway in connecting the outermost islands adjacent to its coast
was not contrary to international law. 48 Taking into consideration the ICJ judgement,
the International Law Commission included in its first draft several provisions allowing
straight baselines to be used in case a state has fringe of islands in the immediate
vicinity of its coast and it further analysed whether other types of archipelagos should
fall under special regime or be treated similarly with isolated islands for purposes of
delimitation of territorial waters. 49 However, the provisions on groups of islands were
not included in the articles because of complexities brought by formations of different
archipelagos where some were compact groups of islands with overlapping territorial
seas while others were scattered and that there was no agreement on the breath of
territorial sea. 50 It may be noted that the Anglo Norwegian Fisheries case judgment was
the very first legal development and a concrete foundation to support the scheme but
akin to previous proposals and submissions, the issue of archipelagos was left
unresolved.
Another attempt was made in the first United Nations Convention on the Law of
the Sea (UNCLOS I) where Indonesia raised the issue of archipelagos with draft articles
sponsored by Yugoslavia and the Philippines with the intention to apply the method of
straight baselines to archipelagos. Under this principle, it was proposed to draw straight
baselines around the outermost points of a coastal archipelago and connect them to the
main island. 51 This is in effect applying by analogy the principle used by ICJ in the
Anglo-Norwegian Fisheries case to mid-ocean archipelagos like the Philippines and

47 Supra, footnote 9 at p. 24 48 Supra, footnote 41 49 Supra, footnote 21 at p. 400 50 Ibid. 51 Supra, footnote 3 at p. 118
12
Tonga. 52 However, the proposal was subsequently withdrawn for lack of international
support. 53 Had the proposal been adopted, its application would enclose huge areas of
water. 54
In the second Law of the Sea Conference, the issue was raised again by the
Philippines and Indonesia, pressing the claim for the special rules on the delimitation
and status of archipelagic waters but the discussion did not reach any conclusion55.
There was no major development on the issue of the archipelagic regime although the
matter was continuously brought to the attention of the Conference.
It was in 1971 that the subject matter was finally considered when the Committee
on the Peaceful Uses of the Sea-Bed and Ocean Floor Beyond the Limits of National
Jurisdiction (Sea-bed Committee), particularly Sub Committee II, took note of the
interests of the concerned states and the subject of archipelagos was placed as item 16 of
its agenda. Attention was given to the special needs and interests of archipelagic states
by setting out the principles which shall govern the regime of archipelagic waters
including the provision of innocent passage through the designated sea lanes for
international navigation through those waters. 56 Consequently, discussion of the issue
began in 1973 where a group of four archipelagic states; the Philippines, Indonesia,
Mauritius and Fiji submitted two proposals entitled “Archipelagic principles as proposed
by the Delegations of Fiji, Indonesia, Mauritius and the Philippines” concerning the
general principles of archipelagic state and the draft articles on archipelagos57. The draft
General Principles and Articles submitted by the proponent States contains the following
provisions 58

General Principles
1. An archipelagic State, whose component islands and other natural
features form an intrinsic geographical, economic and political entity
and historically have or may have been regarded as such, may draw
straight baseline connecting the outermost points of the outermost
islands and drying reefs of the archipelago from which the extent of
the territorial sea of the archipelagic State is or may be determined.
2. The waters within the baselines, regardless of their depth or
distance from the coast, sea bed and the subsoil, and the superjacent
air space, as well as their resources, belong to and are subject to the
sovereignty of the archipelagic State.
3. Innocent passage of foreign vessels through the waters of the
archipelagic State shall be allowed in accordance with its national
legislation, having regard to the existing rules of international law.
Such passage shall be through sea lanes as may be designated for that
purpose by the archipelagic State.
Articles
2. An archipelagic State is a State constituted wholly or mainly by
one or more archipelago.
3. For purposes of these articles an archipelago is a group of islands
and other natural features which are so closely interralated that the
component islands and other natural features form an intrinsic
geographical, economic and political entity or which historically have
been regarded as such.
This proposal is considered as comprehensive and covers the whole range of
archipelagic regimes, different from the proposals made during UNCLOS I, further
giving a clear and concise picture of the general position of states claiming archipelagic
status. 59 It also provides the drawing up of sstraight baselines connecting the outermost

59 Supra, footnote 18 at p. 91
14
points of the outermost islands for the purpose of delimiting the territorial sea and
further establishing a regime in the regime inside the baseline which is considered as sui
generis. 60 Relatively, the United Kingdom also submitted a proposal that sought to
establish “objective criteria and to elaborate the legal status” of archipelagic states in
order to determine which states composed of groups of islands would be eligible for
application of the concept and to preclude other States with remotest archipelagic claim
from using the archipelagic principles to expand their national domain by including vast
ocean spaces. 61 The discussion in the Sea Bed Committee did not only recognize the
pressing needs of the archipelagic states but it also provides a legal framework for the
archipelagic regime. It may be noted that the issue is too complex as it involves the
enclosure of waters previously used in international navigation to form part of the
national territory of one State.
The enclosure of waters was the primary reason for the opposition from the
major maritime states as it would overlap the important shipping routes and would result
in the loss of navigational rights for both their naval and commercial vessels,
particularly in the case of archipelagos like the Philippines and Indonesia. 62
Notwithstanding, the issue on special archipelagic regimes was substantively discussed
and pursued in Sub Committee II taking into account the special position of archipelagic
states in international law and various criteria which would determine whether groups of
islands would constitute archipelagos, as well as the nature of passage through
archipelagic waters and straits. 63 During the Tenth Session of Sub Committee II in 1981,
the concept of archipelago was laid down based on the proposed General Principles and
Articles submitted by proponent states which eventually became part of UNCLOS
1982, where the status of enclosed waters and the rights of passage through archipelagic

60 Ibid. 61 Supra, footnote 21 at p. 401 62 Supra, footnote 3 at p. 119 63 Supra, footnote 41 at p. 3
15
waters were defined. 64 It may be easily understood that the intentions of these states are
founded on the security and integrity of their respective territories. Considering the
configuration of the states concerned, all the islands shall be unified and treated as one
entity by drawing a straight baseline that would connect one island to another to prevent
fragmentation.
2.2 Concept of Archipelagic State under International Law
The concept of the new regime of archipelagos as laid down under Part IV of
UNCLOS 1982 has the following essential features: first, it permits straight baselines to
be drawn around the outermost islands of archipelagos; second, it creates a new legal
concept of archipelagic waters designed to accommodate the navigational interests of
maritime states65. Article 46 of UNCLOS 1982 defines an archipelagic state as “a state
constituted wholly by one or more archipelagos and may include other islands.”
In order to have a better view of the concept of an archipelagic state, the
definition of archipelago should be discussed first. Archipelago has been defined in
Article 46 (b) as “a group of islands, including parts of islands, interconnecting waters
and other natural features which are so closely inter-related that such islands, waters and
other natural features form an intrinsic geographical, economic and political entity, or
which historically have been regarded as such.” In its strict geographical terms,
archipelago means a formation of two or more islands which geographically may be
considered as a whole. 66 It includes not just insular natural formations but also noninsular formations, like reefs, and the areas of the sea around them among which there
must be a close interrelationship thereby constructively forming a single physical and

64 Ibid., at p, 101 65 Supra, footnote 3 at p. 120 66 Clive R. Symmons, The Maritime Zones of Islands in International Law, Leiden: Martinus Nijhoff
Publishers, 1979 at p. 60
16
economic entity. 67 The two or more islands must be so situated as to be capable of being
geographically considered as a whole or a unit. 68 In this regard, the mere existence of
islands does not qualify as an archipelago if they are not closely situated physically
through interconnecting waters to form as a whole.
Taking into consideration the definition and descriptions of an archipelago, an
archipelagic state is comprised of groups of islands that are described in paragraph (b)
Article 46. There are several aspects to be noted in the definition of an archipelagic
state.69 First, it was adopted to reflect the actual situation of states having archipelagic
claims such as Papua New Guinea which is comprised of a main archipelago and two
other archipelagos, or Fiji which has far flung islands, or in case of Indonesia and the
Philippines which both have only one archipelago. Secondly, the requirements of Article
46 must be complied with where a group of islands cannot constitute an archipelagic
state if the islands are not closely interrelated as to form an intrinsic geographical,
economic and political entity or have not been historically regarded as such.
In line with this, if a particular country consists of a group of islands,
interconnecting waters and other natural features, it may establish its claim as
archipelagic state provided that the islands form an intrinsic geographical, economic and
political entity or the islands must be subject to a single government. 70 Additionally, a
country may establish a claim upon the condition that the islands, parts of islands,
intervening waters and other natural features have historically been regarded as an
intrinsic geographical, economic and political entity. 71 The historical factor is an
alternative to geographical, economic and political requirements rather than additional

67 Ibid. 68 Ibid. 69 Supra, footnote 18 at p. 126 70 Supra, footnote 20 at p. 171 71 Ibid., at p. 171
17
thereto. 72 Hence, the primary consideration to be regarded as an archipelago is the
proximity of groups of islands to one another in order to form one geographical entity.
Related to the definition provided under paragraph (a), it requires that an
archipelagic state be constituted wholly by one or more archipelagos. 73 It further
requires the exclusion of continental states which possess non-coastal archipelagos like
Denmark, with respect to the Faroes; Equador pertaining to the Galapagos Islands and
Spain with regard to the Canaries. 74 This means that these States cannot draw
archipelagic baselines around such islands. 75 Simply put, the archipelagic regime is not
applicable to groups of islands belonging to continental states.
Consequent to the concept of archipelagic states is the archipelagic waters or the
waters within or enclosed by the archipelagic straight baseline system which falls under
special legal regime. Such waters are neither internal waters nor territorial sea although
they bear similarities with the latter. 76 Article 47 of UNCLOS states that “an
archipelagic state may draw straight archipelagic baselines joining the outermost points
of the outermost islands and drying reefs of the archipelago…” It bears stressing that
baselines have a direct connection to the outer limits of maritime zones because the
breadth of the territorial sea, the contiguous zone, exclusive economic zone and
continental shelf of an archipelagic state are measured initially from the baseline. For
purposes of delimiting its internal waters, the archipelagic state may draw closing lines
across the mouth of a river, the mouth of a bay or the outermost harbour works. 77 The
waters so enclosed are internal waters, not archipelagic waters based on Article 50
considering that it is within the archipelagic baseline. 78 This means that closing lines

48 http://books.google.se 10 June 2010 76 Supra, footnote 3 at p. 125 77 S.P. Jagota, Maritime Boundary, Leiden: Martinus Nijhoff Publisher, 1985 at p. 33 78 Supra, footnote 3 at p. 125
18
apply only with respect to the mouth of the rivers, across bays and using permanent
harbour works in accordance with Articles 9, 10 and 11 of UNCLOS, respectively, and
delimitation under Article 50 refers to the establishment of a line delimiting the internal
waters and separating those waters from archipelagic waters. 79 However, before an
archipelagic state may draw archipelagic baselines, it must satisfy the objective criteria
under Article 47, as well as the requirement that it consists of one or more
archipelagos.80
It may be recalled that among the opposing views to the establishment of this
new regime in international law is the absence of objective criteria to which the regime
should apply. 81 However, this issue was basically addressed by Article 47 by providing
objective standards for drawing archipelagic baselines which include: maximum length
of baseline (not exceeding 100 nautical miles); the minimum and maximum water-toland ratios within those baselines; conformity of the baselines to the general
configuration of the archipelago and the restrictions on the point to and from which
baselines shall be drawn. 82 Article 47 also addressed the problem of protecting and
preserving the rights of neighbouring states which may be affected by the adoption of
archipelagic baselines, through paragraph 5 and 6, respectively, which specifically
provides that the baseline shall not be applied is such a manner as to cut off from the
high seas or the exclusive economic zone and territorial sea of another State and that
existing rights and all other legitimate interests traditionally exercised by the
neighbouring state shall continue and be respected. 83 In effect, these principles meet the
objectives of the archipelagic states to effectively control its territory and at the same
time recognize the interests of other states.

79 Supra, footnote 21 at p. 445 80 Ibid., at p. 415 81Ibid., at p. 418 82 Ibid. 83 Ibid.
19
In line with being an archipelagic state, it exercises sovereignty over the waters
enclosed by the archipelagic baseline including the superjacent airspace, subjacent
seabed and subsoil and all the resources contained therein, pursuant to Article 49. This
right is subject to a number of rights enjoyed by third states deriving from existing
agreements so as to prevent conflict between the rights of archipelagic states under
UNCLOS and its obligation under these agreements. 84
2.3 Struggle to Achieve Recognition of the Archipelagic Principle
As the forerunners for the recognition of archipelagic principles, the Philippines
and Indonesia together with Fiji and Mauritius waited a long period of time for the
international community to recognize the archipelagic principle. These states being
oceanic nations submitted documents to the Sub-Committee II to seek the establishment
of fundamental principles applicable to an archipelagic state to include its rights over the
waters within its baselines as well as the right to innocent passage by other states. 85
Emphases were made on the right of every state to exercise control over its territory and
the difficulty in exercising it by reason of the complicated island networks as well as the
absence of international rules to govern archipelagos. It is worth mentioning that the
claim for special regime was based on the concept of the right of the state to draw
straight baselines around its outermost islands for purposes of measuring its territorial
sea from the baseline and to further consider the waters enclosed as internal waters. 86

84 Supra, footnote 3 at p. 125 85 Supra, footnote 41 at p. 40 86 Supra, footnote 21
20
State Practice
Prior to UNCLOS III, the Philippines and Indonesia already had an established
state practice regarding the delimitation of their territorial waters and determining the
status around and surrounding their islands87. In the case of the Philippines, it submitted
a note verbale to the Secretary General of United Nations in 1955, claiming exclusive
rights over waters within the coordinates of the Treaty of Paris of 1898 which provides
for the cession of the Philippine archipelago by Spain to the United States and specifies
geographical coordinates for the area of the ceded territory. 88 It claimed that “all waters
around, between and connecting different islands belonging to the Philippine
archipelago, irrespective of their width and dimension form an integral part of the
national or inland water, subject to the exclusive sovereignty of the Philippines. ”
Also, in 1961, the Philippine Congress enacted the Republic Act 3048 (as
amended by RA 5446) defining specifically the seventy-nine (79) baselines drawn from
the outermost points of the archipelago, averaging 35 miles each in length and further
describing the waters enclosed by these baselines as internal waters placed under the
sovereignty of the Philippines. 89 In its 1973 Constitution, particularly in Article 1, it
defines national territory as “comprising of all islands and waters and all other territories
belonging to the Philippines by historic rights or legal title including the territorial sea,
the air space, the subsoil, the seabed, the insular shelves and other submarine areas over
which the Philippines has sovereignty and jurisdiction. The waters around, between and
connecting the islands of the archipelago, irrespective of their breadth and dimension,
form part of the internal waters of the Philippines. ”90

87 Supra, footnote 18 at p. 62 88 Ibid., at p. 63 89 Ibid., at p. 64 90 Philippine Constitution of 1973
21
On the other hand, Indonesia proclaimed in 1957 its archipelagic concept and
issued a Government Declaration concerning the Water Areas of the Republic of
Indonesia otherwise known as Djuanda Declaration. 91 It defines both Indonesia’s
territorial waters and internal waters by declaring that “the delimitation of territorial sea
is measured from the baselines connecting the outermost points of the islands of
Indonesia” and it provides that “all waters surrounding, between and connecting the
islands constituting the Indonesian state, regardless of their extension and breadth, are
integral parts of the territory of the Indonesian state, and therefore, parts of the internal
or national waters which are under the exclusive sovereignty of the Indonesian state. ”92
Both the Philippines and Indonesia received protests from major maritime
powers during that time including the United States, United Kingdom, Australia and the
Netherlands with the view that the declaration violated international law and constituted
a major encroachment on freedom of movement on the world’s ocean. 93 They expressed
concern about passage through the archipelagic waters particularly with reference to
warships. 94 The oppositions were based on their view that the freedom of their
respective fleets, whether commercial or military, to navigate through the waters of the
two biggest archipelagic countries would be curtailed and hampered.
The proposal for the recognition of a special regime is founded on the protection
of national territory and promotion of unity within the country. It may be recalled that
during the deliberation before the Sub Committee II in 1974, Indonesia, the Philippines,
Fiji and Mauritius stressed that the concept was essential to the national unity, political
stability, economic, social cultural cohesiveness and territorial integrity. 95 Their waters

would become separating rather than unifying factors if not enclosed and that this would
form pockets of the high seas, open to the activities which might endanger the unity,
security and territorial integrity of the country. 96 The sovereignty of the archipelagic
states and the preservation of same are vital to their basic national unity and the
protection of their waters from intrusion is crucial to their national security97. Although
many countries supported the proposal, it was pointed out that the regime would entail
problems concerning the existing uses of the sea considering that some archipelagic
waters are situated in the middle of inter-oceanic commercial navigation, hence, passage
through said waters should be unrestricted and recognized and should be more than
simple right of innocent passage. 98 The proponents were in effect criticised on the
absence of formulated rules on passage through archipelagic waters.
It is in this regard that the proposal was amended to include provisions on the
right of innocent passage, the extent to which the state could regulate such passage as
well as the designation of sea lanes and set limitations on their powers to make laws and
regulations on the innocent passage of foreign ships through archipelagic waters. 99 It
was emphasised that a delicate balance had to be struck to ensure minimum interference
with interests of maritime states as well as the legitimate interest of transit State. 100
Hence, in order to reconcile the conflicting interests of the sponsoring states and other
States opposed to the regime, they had to limit their powers to enact rules and
regulations that would govern the passage of foreign vessels through their waters,
thereby putting first the interests of other States in order to gain recognition of
archipelagic principle. Based on the foregoing, it is worth mentioning that the great
efforts of these states to seek a regime that would unify their respective territories for the
sake of security and integrity paved the way subject to the interests of other states.

23
Consequently, a new maritime regime of a hybrid nature has been accepted in the
emerging law of the sea and the division of the seas into high seas, territorial seas and
internal waters now includes archipelagic waters. 101 In their 25 year struggle for
recognition as an oceanic archipelagic regime, they have gained advantage by unifying
their respective territories. As pointed out by these states, sovereignty and exclusive
jurisdictions over the waters that serves as links of communication to every island were
vital to archipelagic states, not only to their economy but also to their national security
and territorial integrity. 102 Another advantage is that the extent of the interconnecting
waters is utilized by the inhabitants of the islands for economic purposes, to include the
exploitation of the resources thereof for food and wealth. 103
As previously discussed, the very intention of archipelagic states is to protect
their territorial integrity and national security. This new approach reflected the national
outlook of the archipelagic states as nation states and their aspiration to acquire
territorial unity. 104 The claim for recognition for a special regime does not imply
acquiring extended territory but for self preservation. It is crucial for them to establish
maritime boundaries that would define their territorial limits as sovereign states.

CHAPTER III
BOUNDARY SETTING IN RELATION TO SECURITY
There are five key maritime zones which the coastal state may claim: internal
waters, territorial waters, the contiguous zone, the exclusive economic zone (EEZ) and
the continental shelf and in case of an archipelagic state, it may claim archipelagic
waters within archipelagic baselines. 105 These maritime zones established under
UNCLOS 1982 are of crucial importance to coastal states because they afford them
security in the face of threats of cross-border crimes such as smuggling, illegal migration
and ultimately the threat of terrorism and the use of military force. 106 For this reason,
coastal states assert their right to maritime zones and at the same time set their respective
borders in order to determine span of control over their territory.
It is in this regard that the archipelagic states particularly the Philippines and
Indonesia have become conscious of their national security taking into account the
configuration of the territory where islands spanning a large part of the ocean have made
it difficult for them to exercise effective central authority together with ease of intrusion
by outsiders107. Insofar as the exclusive interest is concerned, the most important fact
here is that a political entity is comprised of a group of islands separated by expanses of
water where exchange and travel between various parts of the state greatly depends on

105 Supra, footnote 20 at p. 42 106 Ibid., at p. 9 107 Kriangsak Kittichaisaree, The Law of the Sea and Maritime Boundary Delimitation in Southeast Asia,

25
the use of the ocean108 . It becomes extraordinarily difficult to exercise control of
implementation of local policies and matters of special importance to all states such as
immigration, entry of alien and import and export problems109. Also, the military aspect
of security has become complicated because of the geographical situation. The state can
hardly maintain a regular watch over all means of access to the various islands or even
to a large island since the ocean areas involved are so vast which makes espionage and
surveillance from the outside less difficult. 110 Hence, there is the desire to enclose their
respective islands and interconnecting waters within a single unit to insulate them from
outside intrusion111.
As sovereign States, it is customary for archipelagic states to take special and
vital interest over their maritime zones. They have to find or establish measures within
the bounds of international law to delimit their boundaries to protect their territorial
integrity.
3.1 Archipelagic Boundary Delimitation
The recognition of archipelagic principle in international law allows archipelagic
states to delimit their respective boundaries and draw baselines that will delineate the
areas of waters and land that are to be measured. Article 47 of UNCLOS prescribes
boundary delimitation of the archipelagic State to determine the general extent of the
archipelago. It also deals with rules for safeguards for neighbouring states which might
be affected as well as the recording and publication of archipelagic baselines.112 The
following provisions of Article 47 of UNCLOS illustrate boundary delimitation:

International Law of the Sea, New Haven: New Haven Press 1987 at p. 412 109 Ibid. 110 Ibid. 111 Supra, footnote 107 at p. 151 112 UN DOALOS, Baselines: An Examination of the Relevant Provisions of the United Nation Convention
on the Law of the Sea, New York: United Nations Publications, 1989 at p. 35
26

1. An archipelagic State may draw straight archipelagic baselines
joining the outermost islands and drying reefs of the archipelago
provided that within such baselines are included the main islands and
an area in which the ratio of the area of the water to the land area of
the land, including atolls, is between 1 to 1 and 9 to 1.
2. The length of such baselines shall not exceed 100 nautical miles,
except that up to 3 percent of the total number of baselines enclosing
any archipelago may exceed that length, up to a maximum length of
125 nautical miles.
3. The drawing of such baselines shall not depart to any appreciable
extent from the general configuration of the archipelago.
4. Such baselines shall not be drawn to and from low-tide elevations,
unless lighthouses or similar installations which are permanently
above sea level have been built on them or where a low tide elevation
is situated wholly or partly at a distance not exceeding the breath of
the territorial sea from the nearest island.
5.The system of such baselines shall not be applied by an
archipelagic State in such a manner as to cut off from the high seas or
the exclusive economic zone or the territorial sea of another State.
6. If a part of the archipelagic waters of archipelagic State lies
between two parts of an immediately adjacent neighbouring State,
existing rights and all other legitimate interests which the latter State
has traditionally exercised in such waters and all rights stipulated by
agreement between those States shall continue to be respected.
7. For purposes of computing the ratio of water to land under
paragraph 1, land areas may include waters lying within the fringing
reefs of islands and atolls, including that part of a steep-sided oceanic
plateau which is enclosed or nearly enclosed by a chain of limestone
islands and drying reefs lying on the perimeter of the plateau.
8. The baselines drawn in accordance with this article shall be shown
on charts of a scale or scales adequate for ascertaining their position.
Alternatively, lists of geographical co-ordinates of points, specifying
the geodetic datum, may be substituted.
27
9. The archipelagic State shall give due publicity to such charts or
lists of geographical coordinates and shall deposit a copy of each
such chart or list with the Secretary-General of the United Nations.
Based on the foregoing, the following rules must be satisfied by the archipelagic
state in drawing baselines: the archipelagic state must include the main islands; the
designated baseline must enclose an area of sea at least as large as the area of enclosed
land but not more than nine times that of the land area; the baseline may not exceed 100
nautical miles in length except that up to three percent of the total number of baselines
enclosing any archipelago may exceed that length, up to a maximum length of 125
nautical miles and it must not deviate from the general configuration of the archipelago
to any appreciable extent.113
Also, regarding the first requirement, “main island” may be construed, depending
on the interest of the archipelagic state, as the largest island of the archipelago or the
most populous island or most economically productive islands or the most pre-eminent
in a historical or cultural sense.114
Further, the purposes of water-to-land ratio of 1:1 and 9:1 are to provide
objective criterion for the concept of an archipelagic state, to limit its application to
relatively compact oceanic island groups and to meet the claims of archipelagic states
participating in the Conference. 115 The lower ratio was selected to exclude those
archipelagos that are dominated by one or two large islands or parts of islands between
which there are comparatively small areas of interconnecting seas such as, the United
Kingdom, Madagascar and Cuba; whereas the upper ratio excludes those widely
dispersed archipelagos because it is impossible to enclose large areas of seas within

113 UN DOALOS, Handbook on the Delimitation of Maritime Boundaries, New York: United Nations
Publications, 2002 at p. 7
114 Ibid., at p. 8 115 Supra, footnote 21 at p. 429
28
archipelagic baselines as in the case of Tuvalu and Kiribati.116 In this regard, the
countries that could enclose waters approximately within the prescribed ratio are
Indonesia and the Philippines with 1:1.8 and 1.1.2, respectively.117
In sum, the very idea of Article 47 is to have a compact and integrated territory
through straight archipelagic baselines that would connect the islands and waters of the
archipelagic State. The archipelagic baseline is the starting point from which the extent
of territorial sea, contiguous zone, the exclusive economic zone and continental shelf
will be measured.
Relatedly, there are baseline options for archipelagic states that are consistent
with UNCLOS which could be identified from existing state practices. 118 First is the
single baseline system. This option allows the inclusion of all the islands and other
natural features and the interconnecting waters that constitute the archipelagic State
within a single composite baseline system. The states like Indonesia, the Philippines and
Cape Verde have applied this system in enclosing their respective archipelagos. Second
option is the multiple baseline system which allows the drawing of archipelagic
baselines around each archipelago forming the archipelagic state. However, each
archipelago should be consistent with Article 46(b) and each enclosure should satisfy
Article 47 on the drawing of archipelagic baselines. The country that was able to apply
this option is Solomon Islands with five archipelagos and has drawn baseline around
each archipelagos. Third is the non-archipelagic straight baseline system. This option
can be applied by States which fall within the definition of archipelagic state and
predominantly consist of one large island. They may draw straight baselines which tie
the coastal islands to the main island, similar to mainland coasts that are fringed by
coastal islands or coastal archipelagos. The advantage of this is that the waters inside the

116 Supra, footnote 20 at p. 176 117 Supra, footnote 3 at p. 123 118 Supra, footnote 18 at pp. 135-136
29
straight baselines then become internal waters rather than archipelagic waters.
Madagascar and Cuba have chosen this option in their respective legislations.
Status of Waters Enclosed and Rights Accorded to the Archipelagic State
There are various terms used to describe the status of archipelagic waters. There
are views that waters landward of straight archipelagic baselines should be described in
the same manner as in the case of waters enclosed landward of the straight baseline
system as provided under the 1958 Convention on the Territorial Sea which was
described as internal119. However, in order not to deviate from the accepted categories of
internal waters, territorial sea and straits used for international navigation, the 4-State
Drafts and the United Kingdom emphasized the sui generis character of the waters
enclosed by archipelagic baselines by adopting a new term archipelagic waters. 120
Hence, the waters within or enclosed by the archipelagic baselines are referred as
archipelagic waters.
The legal status of archipelagic waters is embodied in Article 49 of UNCLOS
where it specifically states the following:
1. The sovereignty of an archipelagic State extends to the waters
enclosed by the archipelagic baselines drawn in accordance Article 47,
described as archipelagic waters, regardless of their depth or distance
from the coast.
2. Their sovereignty extends to the air space over archipelagic waters,
as well as to their bed and subsoil, and the resources contained therein.
3. This sovereignty is exercised subject to this Part.

119 Supra, footnote 66 at p. 68 120 Supra, footnote 9 at p. 114
30
4. The regime of archipelagic sea lanes established in this Part shall
not in other respects affect the status of the archipelagic waters
including the sea lanes, or the exercise by the archipelagic State of its
sovereignty over such waters and their air space, bed and subsoil, and
the resources contained therein.
The archipelagic waters should be distinguished from internal waters. The
concept of internal waters is retained for bays, river mouths and ports in accordance with
Articles 9, 10 and 11. The internal waters in this regard are those created by delimiting
closing lines across bays, rivers and ports, therefore, subject to normal rules while
archipelagic waters are those enclosed by or within the archipelagic baselines. There is
no right of foreign passage over internal waters.121 On the other hand, the archipelagic
state exercises sovereignty over archipelagic waters including seabed and subsoil therein
regardless of their depth or distance from the coast but the exercise thereof is subject to
some limitations in favour of rights of passage for foreign ships and aircrafts.122
These distinctions connote that the archipelagic state exercises absolute
jurisdiction over its internal waters while its rights over archipelagic waters are subject
to certain conditions. It is similar to rights over territorial sea where foreign vessels
enjoy innocent passage and transit passage. With regard to the boundary setting of the
archipelagic state, it meets the objective and requirements of unity and national integrity
of the archipelagic state. It may be understood that if the waters will not be enclosed by
baselines, they will possess the character of international straits where passage of foreign
vessels is a matter of right.
3.2 Introduction of Archipelagic Sea Lanes Passage (ASLP)
It may be recalled that the issue of passage through archipelagic waters was
controversial during the deliberation stage of UNCLOS III. The opposition of major

121 Supra, footnote 107 at p. 164 122 Ibid., at p. 162
31
maritime powers and other states was overwhelming by reason of the obstacles they
would face in commercial navigation, strategic movement of military forces as well as
the right of innocent passage and other existing rights in the event that waters would be
enclosed and placed under jurisdiction of the archipelagic states.
Oppositions contended that once the archipelagic state acquired the exclusive
rights over the waters previously regarded as high seas but now placed under the
sovereignty of that state, foreign military aircrafts or vessels would have no right to
navigate or fly over those waters. On the other hand, the archipelagic states argued on
the grounds of territorial integrity and national security. In order that the archipelagic
concept be acceptable to maritime powers and other states, negotiation and compromise
on navigational rights over archipelagic waters were made. This is where the concept of
archipelagic sea lane passage was introduced as a compromise for gaining archipelagic
state status.
Rights of passage of all states through and over archipelagic waters are the major
limitation to the sovereignty of the archipelagic state123. Worth mentioning are the two
groups of rights of other states over archipelagic waters introduced in UNCLOS III;
these are non-navigational and navigational rights. The former consists of previous
rights being exercised by neighbouring States in archipelagic waters by virtue of
agreement prior to becoming as such; whereas, the latter includes right of innocent
passage which had been present since UNCLOS I and the new concept of archipelagic
sea lane passage124.
The existing agreements are those entered into by the archipelagic States with
other States that will be affected once an archipelagic State draws its baseline. Taken as
example are the immediately adjacent States of Malaysia and Indonesia. They entered

into an agreement on 25 February 1982 on the breadth of navigational corridor entitled
The Treaty Between Malaysia and the Republic of Indonesia Relating to the Legal
Regime of Archipelagic State and the Rights of Malaysia in the Territorial Sea and
Archipelagic Waters as well as in the Airspace above the Territorial Sea and
Archipelagic Waters and the Territory of the Republic of Indonesia Lying Between East
and West Malaysia, (otherwise known as Jakarta Treaty)125. The treaty provides a 20
mile corridor between their borders particularly on east and west part for navigation
purposes. It means that the stipulations regarding the use of waters enclosed by
archipelagic baselines stay although such waters were placed under the jurisdiction of
Indonesia.
Relatedly, non-navigational rights include the interest of other States in lying
submarine cables within the scope of “direct communication”126. The establishment of
archipelagic baselines does not affect this particular right of other States.
On the other hand, navigational rights involve right of innocent passage and
archipelagic sea lanes passage. Similar to the innocent passage rights that could be
exercised by a State over the territorial sea of another State, it could also be exercised
through archipelagic waters pursuant to Article 52 of UNCLOS. The rule on innocent
passage shall be governed by Part II Section 3 of UNCLOS127. Passage, in this regard,
means navigation through the territorial sea for the purpose of (a) traversing that sea
without entering internal waters or calling at a roadstead or port facility outside internal
waters or (b) proceeding to or from internal waters or a call at such roadstead or port
facility and it shall be continuous and expeditious except for anchoring in normal access
of navigation, in force majeure or when assisting another vessel128. Also, Article 19 of

125 Ibid., at p159 126 Supra, footnote 9 at p. 117 127 UNCLOS Article 52 – (1) Subject to article 53 and without prejudice to article 50, ships of all States enjoy the
right of innocent passage through archipelagic waters, in accordance with Part II, section 3. (2) The archipelagic
State may, without discrimination in form on in fact among foreign ships if such suspension is essential for the
protection of its security. Such suspension shall take effect only after having been duly published. 128 UNCLOS Article 18
33
UNCLOS provides that a vessel exercising the right of innocent passage must not
engage in conduct which is prejudicial to the peace, good order or security of the coastal
state. Further, it is a requirement under Article 21 for foreign vessels exercising the right
of innocent passage through archipelagic waters to comply with laws and regulations of
the archipelagic State as well as the international rules against collision at sea.
Another navigational right is referred to as the specialized regime of the right of
archipelagic sea lane passage. Based on Article 53 of UNCLOS, archipelagic sea lane
passage means the exercise of the rights of navigation and overflight in normal mode
solely for the purpose of continuous, expeditious and unobstructed transit between one
part of the high seas or an exclusive economic zone and another part of the high seas or
an exclusive economic zone129. This right could be exercised in two instances, first, in
all normal passage routes used for international navigation or over flight through or over
archipelagic waters and its adjacent territorial sea; second, in sea lanes or air routes
which the concerned archipelagic state has specifically designated130.
3.3 Aspects of Right of Archipelagic Sea lane Passage
This particular regime guarantees that ships and aircrafts of other States have the
right to pass through and over archipelagic waters on designated sea lanes and air
routes131. It is very much different from innocent passage. The following instances
constitute distinctions between two principles of innocent passage and archipelagic sea
lane passage with regard to passage through archipelagic waters132:

129 Supra, footnote 12 at p. 522 130 Supra, footnote 23 at p. 318 131 Supra, footnote 123 at p. 119 132 Hashim Djalal, Indonesia’s Archipelagic Sea Lanes, in Robert Cribb and Michelle Ford (Editors)
Indonesia Beyond the Water’s Edge, Pasir Panjang: ISEAS Publishing at p. 60
34
1. The right of innocent passage requires that submarines and
other under water vehicles should navigate on the surface,
showing their flags; whereas in archipelagic sea lane passage,
underwater vehicle is allowed to navigate under normal mode
which is possible that it pass underwater;
2. There is no right of over flight in areas where innocent
passage is allowed while in archipelagic sea lane, over flight is
permitted;
3. The right of innocent passage could be suspended in certain
cases like when there is military exercise or the State has to deal
with local crises but archipelagic sea lane passage cannot be
suspended, it may only be substituted;
4. With regard to warships, there are no precise rules under
international law that would require countries to give prior notice
on innocent passage of warships; other countries necessitate
prior notice while some do not require but in archipelagic sea
lane passage, prior notification on the passage of warship
through it is explicitly not required;
5. The provisions on archipelagic sea lane do not include the
possibility of cooperation between the archipelagic State and
user States in terms of establishment of safety rules on
navigation and the prevention and control of pollution from ship
through archipelagic sea lane are not covered by this concept.
It may be understood from the above mentioned distinctions that the rules on
innocent passage are more stringent than that of the archipelagic sea lane passage.
Violations of conditions on innocent passage that would affect national security of the
State will give rise to suspension of the right. However, the same cannot be done in
archipelagic sea lane passage because it is designed for continuous, unobstructed and
expeditious passage of foreign vessels.
Another aspect of archipelagic sea lane passage is that it is almost similar to the
right of transit passage through and over straits used for international navigation. Transit
passage means the exercise of freedom of navigation and overflight, in accordance with
Part III UNCLOS, solely for the purpose of continuous and expeditious transit of the
35
strait between one part of the high seas or an exclusive economic zone and another part
of the high seas or an exclusive economic zone (Article 38). It is the same as freedom of
the high seas in the aspect of continuous and expeditious passage133. Moreover, Article
54 of UNCLOS specifically states that provisions on transit passage shall be applied
mutatis mutandis to the regime of archipelagic sea lane passage. Emphasis should be
made on the following similarities134:
1. The rights of transit passage and archipelagic sea lane passage include
overflight for aircraft as well as navigation for ships;
2. Ships exercising right of transit or archipelagic sea lane passage may
use their normal mode of transit, hence, surface warship may pass
through sea lane in a manner necessary for their security to include
formation steaming and recovery of aircraft;
3. Both rights may never be suspended for reason of national security,
even temporarily.
The foregoing circumstances do not apply to right of innocent passage. On the
other hand, these rights differ from one another under the following aspects:135
1. Transit passage signifies exercise of freedom, while archipelagic sea
lanes passage is the exercise of the rights of navigation or overflight;
2. As a matter of general right, ships and aircrafts enjoy right of transit passage
through straits. On the other hand, they enjoy a general right of sea lanes
passage if the archipelagic state designates; otherwise this right “may” be
exercised through the routes used for international navigation;
3. Unlike in the case of transit passage, both sea lanes and air routes must be
established on axis lines within archipelagic waters;

133 Supra, footnote 9 at p. 89 134 Supra, footnote 123 at p. 119 135 Supra, footnote 13 at p. 25
36
4. All normal passage routes used for international navigation should be
included in designating archipelagic sea lanes and air routes, whereas; it is
not a requirement in transit passage;
5. The right of overflight under archipelagic sea lanes passage is restricted to
air routes above sea lanes, unlike in the freedom of overflight within transit
passage regime. This means that overflight should be made strictly above the
designated sea lanes or routes normally used for international navigation, in
the absence of designated sea lanes.

Additionally, although its designation is not mandatory as the phrase ‘may
designate’ is expressly stated in Article 53, the right of archipelagic sea lane passage
applies by default because of paragraphs (4) and (12) thereof which provide that sea
lanes shall include all passage routes used for international navigation through
archipelagic waters and that if no sea lanes are designated, the right may be exercised
through routes normally used for international navigation136.
In the event the archipelagic sea lane will be established in narrow channels, the
archipelagic State may prescribe traffic separation scheme for the safe passage of ships
based on Article 53 (6). Also, the proposal to establish a sea lane has to be approved by
a competent international organization, in this case the International Maritime
Organization (IMO) which has jurisdiction over shipping and navigation questions137.
Once the proposal for its designation is approved by the IMO, ships and aircraft of all
states, to include military ships and aircraft, may enjoy the right of archipelagic sea lane
passage continuously and expeditiously through the archipelagic waters138.
Considering that archipelagic sea lane passage is similar to transit passage in
major aspects, the rights afforded to archipelagic states over archipelagic sea lane are
very limited. It grants maritime nations non-suspendable rights of passage through an

136 Supra, footnote 132 at p. 62 137 Supra, footnote 18 at p. 169 138 Supra, footnote 123 at p. 120
37
archipelago 139 . This is the greatest among the considerable responsibilities of the
archipelagic States to the international maritime community and the price they have to
pay for the advantages of gaining archipelagic status140.
Purpose of Archipelagic Sea Lanes
As provided under Article 53 of UNCLOS, an archipelagic state may designate
sea lanes and air routes above them for continuous and expeditious passage of foreign
ships and aircraft through its archipelagic waters and territorial sea and air space above.
It shall include normal routes used for international navigation. The sea lane connects
one part of the high seas or exclusive economic zone to another part of the high seas or
EEZ or territorial sea of another state. In order to reach the other part of the high seas,
the vessel could traverse through the archipelagic sea lane. Although it is similar to
transit passage in straits used for international navigation, it is adjusted to reflect the
differences between the vast expanses of ocean that become archipelagic waters as well
as narrow passages that comprise most straits used for international navigation141.
Basically, archipelagic sea lanes cater to the needs of user states so they could
have uninterrupted navigation through archipelagic waters. They facilitate the
unobstructed passage of military vessels and aircrafts over the waters of the archipelagic
state142.
In order to protect its maritime security in relation to the establishment of
archipelagic sea lane passage, the archipelagic state may, under Article 42 UNCLOS,
adopt laws and regulations relating to sea lane passage in respect of safety of navigation,

38
prevention and control of pollution, prevention of fishing and the loading and unloading
of any commodity, currency or person or sanitary laws or regulation.
3.4 Maintaining Territorial Integrity
In asserting their rights to maritime spaces, the archipelagic states have to agree
to the establishment of sea lanes for passage of foreign ships in the archipelagic waters.
Although the archipelagic states preferred the use of these sea lanes to be subject to the
rule of innocent passage, demands from maritime states eventually led to a regime of
passage comparable to transit passage which is less stringent143. The interests of the user
states have been taken into account in order that their freedom of navigation will not be
obstructed.
However, the archipelagic states have to balance their interests of maintaining
territorial integrity with the right of user states to navigate uninterruptedly through the
archipelagic waters. The two biggest archipelagic states and the primary proponents of
archipelagic principles, Indonesia and the Philippines have to consider their respective
security interests, economic interests as well as the environment.
In protecting the security interest, archipelagic state may limit the number of sea
lanes designated and may chose the shortest possible routes or it may limit certain types
of vessels or vessels carrying certain types of cargos 144 . The archipelagic state is
permitted to adopt laws or regulations that will govern the exercise of archipelagic sea
lanes passage but should not result to hampering or impairing the relevant right of
passage145 The vessels and aircrafts are obliged to comply with the following conditions

143 Supra, footnote 107 at p. 161 144 Supra, footnote 18 at p. 170 145 Supra, footnote 23 at p. 319
39
under Articles 39 and 40 of UNCLOS while exercising the right of archipelagic sea lanes
passage: 146
1. ships and aircraft exercising right of archipelagic sea lane
passage shall proceed without delay;
2. they are not allowed to cause any threat to the security of
archipelagic State;
3. ships shall comply with international rules for preventing
collisions between ships;
4. they shall take necessary precautionary measures to prevent
causing of pollution to the marine environment.
While it is true that designating archipelagic sea lane passage is the ultimate
responsibility of archipelagic States to the international community, it shall also be
considered that maintaining territorial integrity is paramount to other obligations. There
are certain important interests which the archipelagic state cannot give up, for instance
its maritime security, to satisfy concerns of the user states. Hence, designation of
archipelagic sea lanes shall be viewed as the greatest contribution of archipelagic states
to the international community, particularly to major maritime powers because their
right to navigation through archipelagic waters is being upheld and guaranteed.

CHAPTER IV
INDONESIA’S COMPLIANCE

The archipelagic sea lanes passage (ASLP) is extremely important to
international commercial and naval navigation particularly through Indonesian and
Philippine archipelagic waters and international straits. 147 Major maritime powers
claimed uninterrupted passage through these archipelagos for reasons of international
trade and strategic security, like the United States for the transit of its submarine to and
from Guam, as well as Japan for the passage of its oil tankers to and from the Persian
Gulf.148 From the view point of these maritime powers these archipelagic states hamper
free navigation because they lie at the crossroad of two great oceans, Indian and Pacific
Oceans. Indonesia, in particular, the largest archipelagic state in the world with 5.8
million square kilometres consisting of 0.3 million square kilometres of territorial sea,
2.8 million square kilometres of archipelagic waters and 2.7 million square kilometres of
EEZ, is lying not only between these oceans but also between two continents, Asia and
Australia.149 Hence, absence of sea lanes would considerably delay navigation activities
of their commercial and military fleets because they have to take a long route.

It was previously pointed out that it is not mandatory upon the archipelagic state
to designate archipelagic sea lanes passage. However, if it chooses to designate, Article
53(4) requires that the designation includes all normal passage routes used for
international navigation. From the Indonesian perspective, this means that it can only
exercise its full sovereignty over its archipelagic waters if it designates a full regime of
archipelagic sea lanes through its waters. 150 The fact that a number of straits are also
located in Indonesia like the Straits of Malacca and Singapore, the Sunda Strait and
Lombok Strait, means that there is a need to designate sea lanes which are not
duplicative for purposes of enhancing safety of navigation, protection of the
environment and strengthening the security of the maritime domain. 151

42
In this regard, Indonesia started the process of designating archipelagic sea lanes
passage in its waters in 1994 by conducting national surveys, and in 1995 it undertook
national inter-agency coordination. 152 In 1996, it began its consultations with the
International Hydrographic Organization and with interested user states such as
Australia, Japan, the United States and the United Kingdom on the designation of
archipelagic sea lanes as well as the rules that will govern the same. 153 Since the
beginning of the negotiation, it has been the intention of the United States, whose prime
mission is to strengthen the capability to provide global reach through sea power, to
ensure that all normal routes and transit through the area would be properly included in
the designation. 154 With regard to Australia, its concern is not only regional security but
also economic aspects in case of any erosion of free access through the sea-air gap to
their north. 155
On the other hand, Indonesia had taken into account important factors, from
technical requirements to environmental matters, before the axis of sea lane was
decided. These include the presence of maritime installations and structures, underwater
cables and pipelines, the needs of international vessels and aircraft that intend to pass
through or over Indonesian waters, the capability of law enforcement agencies to
monitor the archipelagic sea lanes, the maintenance of peace, stability and security in the
country’s heavily populated coastal zones, the intensity of fishing activities and the need
to protect marine parks and ecosystems. 156 Considering that the establishment of
archipelagic sea lanes is on territorial waters of the archipelago, it has to re-adjust its
archipelagic starting lines in the Natuna Sea.157

43
Additionally, Indonesia had indicated that an east – west sea lane through the
Java Sea, which is a major normal route for international navigation, was not likely to be
included in the proposal. The United States and Australia which are concerned about the
non-inclusion of other normal routes opposed the proposal stressing on the requirements
of UNCLOS 1982 that all normal routes should be included in designation of
archipelagic sea lanes, hence it urged Indonesia not to submit a proposal unless it
include all normal routes. 158 Notwithstanding, Indonesia submitted in 1996 its proposal
to IMO for the designation of archipelagic sea lanes passage in accordance with Article
53(9), with rules to govern their use which resulted from coordination with the user
states.159
4.1 The Indonesian Submission
The United States maintains its position that the Indonesian submission should
be regarded as a partial designation only; that the right of archipelagic sea lanes passage
shall continue to be applied in routes used for international navigation through the
archipelago and that the right of innocent passage should not be affected by the
designation of archipelagic sea lanes passage.160 Australia’s view in this regard is that
the proposed mechanism shall be interpreted in line with the issue of normal passage
routes, number and location of sea lanes and that the outcome of the consideration of the
proposal shall reflect the balance of interests of the user states and archipelagic state.161
In line with the Indonesian proposal, the IMO issued Resolution MSC. 71(69) entitled
Adoption of Amendments to the General Provisions of Ships’ Routing (RESOLUTION

A.572(14), as amended) where the General Provisions for the Adoption, Designation
and Substitution of Archipelagic Sea Lanes (GPASL) is embodied in Annex 2 thereof to
serve as guidelines for the adoption of proposals on archipelagic sea lanes (see Annex
1). GPASL provides the concept of a “partial archipelagic sea lane proposal” which
means the proposal made by an archipelagic state which does not meet the requirement
to include all normal passage routes and navigational channels as required by UNCLOS
(paragraph 2.2). In 1998, in its 69th Maritime Safety Committee session through
Resolution MSC 72(69) (see Annex 2) the IMO accepted the proposal as partial
designation of archipelagic sea lanes because it represented only north/south routes.162
This means that routes used for international navigation which were not covered in the
proposal remain available for archipelagic sea lanes passage while the remainder of
archipelagic waters is available for innocent passage.163 With regard to the east-west
route from the southern end of the Malacca Strait to the Arafura Sea, it will be required
to satisfy the IMO rules on designation of archipelagic sea lanes passage.
The accepted proposal of Indonesia consists of the following three north-south
routes of archipelagic sea lanes passage:164
ASL I: Sunda Strait – Karimata Strait – Natura Sea – South 论文帮助/论文写作服务/负担得起我及时提交我最好的质量 – China Sea

and lastly ASL III, which is in the southern part with three branches, facilitates the
navigation from Timor Sea and Arafura Sea to the Pacific Ocean through Sawu Sea,
Banda Sea, Seram Sea and Molucca Sea. 165 All these routes were indicated in the map
submitted to the IMO. It may be noted that the designation did not include east-west
route although the user states insist on this issue.

The IMO Resolution was subsequently implemented through Indonesian
Government Decree No. 37/2002 dated 28 June 2002 and referred to as Alur Laut

165 Ibid.
46
Kepulauan Indonesia (ALKI) which made it the very first archipelagic State to designate
archipelagic sea lanes passage (Annex 3).166 This decree was primarily based on the
rules of UNCLOS 1982 and the outcome of consultations with the user states. It
acknowledges certain rights of user states.167 Article 2(1) thereof provides the right of
innocent passage of foreign vessels through Indonesian territorial seas and archipelagic
waters for transiting from one part of the EEZ or high seas to another part of the EEZ or
high seas; Articles 2, 3 and 11 prescribe the right of archipelagic sea lane passage
through certain parts of the Indonesian territorial seas and archipelagic waters referred to
in the Decree as specific archipelagic sea, while Article 4(1) provides the right to
navigate in normal mode solely for the purpose of continuous, direct, expeditious
passage and unobstructed transit in line with Article 53 (3) of UNCLOS. The Decree
also requires that ships and aircrafts exercising the right of archipelagic passage and
overflight are not allowed to deviate more than 25 nautical miles from the axis of the
archipelagic sea lane and may not navigate or fly closer to the coast than 10% of the
distance between the nearest points on the islands bordering the sea lane.168
With the adoption of the proposal and its subsequent enactment into national
legislation, Indonesia has indicated its intention to balance the interests of the user states
with its own national interest although the user states continue to press the issue on
additional routes.
4.2 The User States’ Perceptions on Indonesia’s Partial ASLP
Designation
The prerogative given by UNCLOS to the archipelagic states to submit sea lanes
that they want to be approved may give rise to a situation where they may only propose

166 Supra, footnote 132 at p. 63 167 Ibid. at p. 66 168 Ibid.
47
a small number of sea lanes for designation that best serve their interest.169 This is
reflected in the submission of Indonesia which has become the primary concern of the
United States and Australia because an east-west passage is not included in the
designation of archipelagic sea lanes passage although it is a normal route under
UNCLOS. According to a study conducted in the US Naval War College in 1998,
potential consequences to operational planning elements may impact the operational
commander in the case that Indonesia fails to provide or designate a sufficient number of
sea lanes particularly through the east-west corridor. 170 These include effects on the
sequencing and synchronization of forces if the routes in the archipelago are insufficient
because alternative routing will be employed; it will expand or extend the overall force
structure and logistics trail thereby committing more assets to support movements,
deception actions and operational protection requirements and an increased risk to force
structure is immediately present because of the funnelling of forces created as both
commercial and military assets are forced to utilize designated archipelagic sea lanes.
This means that insufficient routes may reduce the flexibility available to operational
commanders in passing through Indonesian archipelagic waters which will definitely
hamper operations. In a related study in 1999, in the case that the limited number of
archipelagic sea lanes will not affect operational plans, it will still require changes at the
tactical level where ships will need to remain within the designated sea lane and will no
longer be able to operate close to the shore for safety reasons.171
Relatively, while Indonesia maintains before the international arena that its
designation of archipelagic sea lanes is only partial and that the right of archipelagic sea
lanes passage is available to transiting vessels that navigate through normal routes used

169 Supra, footnote 154 at p. 8 170 Ibid. at p 10 171 Supra, footnote 158 at p. 22
48
for international navigation, Government Decree 37/22 provides otherwise. 172 It is
stated in this law that innocent passage is the only right of passage that could be
exercised outside the three designated sea lanes, which creates difficulty for transiting
vessels.173
Considering that the user states are persistent in their stand that east-west route
passage is considered as normal route, the US asserted what it claimed to be customary
right, sent an aircraft carrier USS Carl Vinson and five fighter aircrafts on manoeuvres
near the island of Bawean in Java Sea in July 2003, which created inconvenience in
Indonesia.174 Five F18 Hornet jets escorting the aircraft carrier were detected by Air
Force radar manoeuvring for more than 2 hours over Bawean Island in East Java.
Indonesian government officially lodged its “deep concern” about the incident through
US Ambassador in Indonesia during that time, stating that the US Navy F18 Hornets
may be violating Indonesia’s airspace.175 Aside from this incident, it has been noted that
some user states claim that they are passing through international waters even if they are
navigating through Indonesian waters and even in the designated archipelagic sea lanes.
Indonesia is not pleased with this perception but it has so far tolerated the breaches for
the sake of understanding the balance that was so painstakingly negotiated over many
years in order to avoid unnecessary conflict.176

4.3 Present Interpretation of Archipelagic Sea Lanes Passage
The issues raised by the user states particularly the United States and Australia
were all embodied in the GPASL. The designation of archipelagic sea lanes passage is
regarded as partial under this General Provision. This means that Indonesia is still
required to propose for adoption further archipelagic sea lanes including all normal
routes and navigational channels; it has to inform the IMO of its plans for the future
designation and submission of additional sea lanes, and foreign states are entitled to
exercise the right of archipelagic sea lanes passage through all routes used for
international navigation.177 However, the GPASL is considered as against the provision
of Article 53(4) as the article provides only a designation covering all normal routes
used for international navigation.178
Also, this brings the situation where the user states will continue to request
additional routes for archipelagic sea lanes passage and would take away the prerogative
given to the archipelagic state of determining the necessary archipelagic sea lanes for
management of maritime traffic.179 Further, the consideration by IMO of Indonesia’s
submission reflects that the regime is focused on the preservation of interests of user
states and further diminishes the control of archipelagic states. 180 If this is the case, this
situation is not favourable to the archipelagic state because its position may no longer be
equal to that of the user states. Article 53 may not be implemented by other archipelagic
states and they may choose to apply restrictive policies to govern the use of its waters. In

the case of Indonesia, it chose to designate archipelagic sea lanes passage and
considered it as a step closer to implementing its rights over its waters.181
4.4 Factors Affecting the Archipelagic Sea Lanes
It bears stressing that in designating archipelagic sea lanes passage, it would be
important for an archipelagic state to take into great consideration its legitimate security
interests as well as economic and environmental matters.182 Indonesia has taken note of
these factors, particularly the matter of security. The interpretation of the user states on
Indonesian archipelagic waters and the archipelagic sea lanes passage as international
waters is a security issue because it involves claim of jurisdiction over Indonesian
waters. Conflict may arise if both states assert their respective rights over these waters.
Recall the incident in July 2003 involving US F18 Hornet jets detected flying Indonesian
airspace without prior clearance while escorting the aircraft carrier USS Carl Vinson that
alarmed the government.183 Although there were no incidents of similar nature that have
been recorded since that time, it does not follow that it will not be repeated in the near
future.
Other major factors that affect archipelagic sea lanes passage and the larger part
of Indonesian waters are the maritime crimes of piracy and armed robbery. It may be
noted that ASL I passes through the Natuna Sea before dividing towards the Singapore
Strait and South 论文帮助/论文写作服务/负担得起我及时提交我最好的质量 – China Sea. In 2009, International Maritime Bureau (IMB)184 identified
Natuna Islands, Anambas and Mangkai islands as the three piracy-prone areas in

51
Indonesian waters. 185 The IMB also issued warnings to mariners to take necessary
precautionary measures while passing through these waters (see Annex 4). The pirates
are armed with guns, knives or machetes and many attacks have gone unreported.
Similarly, the Regional Cooperation Agreement on Combating Piracy and Armed
Robbery against Ships in Asia (ReCAAP)186 made a special report on piracy incidents in
Natuna, Anambas and Magkai Islands where a total of eleven incidents of piracy attacks
on vessels underway transpired in the area between January to June 2010. The analysis
of ReCAAP in these incidents is that those reported in 2008 and 2010 were more
scattered and occurred in a larger area than those in 2009.187 These two reports signify
that piracy and armed robbery, as the case may be, are taking place in the area where
ASL I lies and divides to Singapore Strait and South 论文帮助/论文写作服务/负担得起我及时提交我最好的质量 – China Sea. The pirates operate in
these areas considering that the waters are less monitored because of the distance.
More attention must also be given to terrorism at sea as a problem that is likely
to grow in the future. Although there have been no major incidents of terrorist attacks on
board the vessel in the areas where three archipelagic sea lanes traverse, in case a
terrorist attack were to occur, it would have an immense impact not only on the security
of the state but also on the global economic and political situation. The trade would
definitely be disrupted because these areas may be closed for shipping or fishing in case
of a single terrorist attack. Taking into account the total value of trade passing through
archipelagic sea lane, 300USD trillion annually that would be lost.188 In the event that
Sunda Strait and the Lombok-Makasar Strait (ASL II) would be blocked, the only detour
available is to go around the south of Australia, hence transporting crude oil from

Middle East to Japan would add two weeks to the voyage and additional eighty (80) or
so tankers would be needed to fulfil crude oil requirements.189 Terrorism at sea in this
regard cannot be discounted because the vessels are regarded as vulnerable targets and
sea lanes are being used by international vessels whether commercial or military.
Terrorists could gain the international attention that they always seek in staging an attack
or series of attacks.
The significance of Indonesian sea lanes cannot be discounted. They definitely
provide the shortest routes from the Indian Ocean to the rest of the world. While there
are still important practical issues to be resolved relative to Indonesian sovereignty and
the reasonable rights of international shipping to pass through Indonesian waters,
Indonesia chose to designate archipelagic sea lanes passage and considered it as a step
closer to implementing its rights over its waters.190

CHAPTER V
THE PHILIPPINES OUTSTANDING CONCERNS

Similar to Indonesia, the Philippines, as one of the principal sponsors of the
archipelagic principle brought this concept to the international community for the sake
of unity of land, water and people and territorial integrity. The Philippine archipelago
consists of 7,107 islands which are linked by waters. It has a total coastline length of
36,289 kilometres and total land to water ratio of 1:1.2. The land area is approximately
300,000 square kilometres and total water area of 2.2 million square kilometres.191 It lies
between the Indian Ocean and the Pacific Ocean. The waters around the archipelago are
important to international navigation because commercial ships passing through the
Malacca Strait bound for Guam and Hawaii, must pass through Philippine archipelagic
waters.192 These geographic characteristics suggest the need for the country to protect
the security of its waters from unlawful use, external threats and to preserve marine
resources and the environment.193
Prior to UNCLOS 1982, the Philippines had already embraced the archipelagic
doctrine and incorporated it in its national legislations in 1961 through the Republic Act
(RA) 3046 as amended by RA 5446 of 1968 as well as in the1935 Constitution and the

1973 Constitution. Further, it adopted the principle in Article I of the 1987 Constitution
which specifically defines Philippine territory as:

“The national territory comprises the Philippine archipelago,
with all the islands and waters embraced therein, and all other
territories over which the Philippines has sovereignty or
jurisdiction, consisting of its terrestrial, fluvial and aerial
domains, including its territorial sea, the seabed, the subsoil, the
insular shelves, and other submarine areas. The waters around,
between, and connecting the islands of the archipelago,
regardless of their breadth and dimensions, form part of the
internal waters of the Philippines.”194
From the time the Philippines issued note verbale in 1955, its state practice has
always been put in question as to whether the government complies with international
law because its laws on maritime zones are not consistent with it. When the Philippine
government signed the UNCLOS 1982, it issued a written declaration that “the
provisions of the Convention on archipelagic passage through sea lanes do not nullify or
impair the sovereignty of the Philippines as an archipelagic state over the sea lanes and
do not deprive it of authority to enact legislation to protect its sovereignty, independence
and security.” 195 It further stated that “the concept of archipelagic waters is similar to
the concept of internal waters under the Constitution of the Philippines, and removes
straits connecting these waters within the economic zone or high sea from the rights of
foreign vessels to transit passage for international navigation.” This very declaration has
earned adverse reactions from maritime powers charging that the Philippines was
making an unauthorized reservation or evading the obligations of the Convention. In
response, the Philippines issued another declaration in 1988 assuring the State Parties to
the UNCLOS 1982 that it would abide by the provisions of the Convention.196

55
However, it may be understood that the conflicting regimes in domestic laws
were enacted prior to its ratification of the Convention. 197 The Philippines is
continuously revisiting and harmonizing its laws with UNCLOS. Recent development in
this regard was the enactment in March 2009 of RA 9522 otherwise known as an Act to
Amend Certain Provisions of Republic Act No. 3046, as Amended by Republic Act No.
5446, to define the Archipelagic Baselines of the Philippines, and for Other Purposes. It
adopted the straight baselines system consistent with Article 47 of UNCLOS. This
particular legislation was deposited with the UN Secretary General on 21 April 2009, in
compliance with Article 47 (9).
5.1 Perspective as an Archipelagic State
From the country’s standpoint, there is no doubt that the Philippines is
determined to fulfil its duties and obligations under the Convention. However, it is how
these obligations and duties may be best carried out while at the same time protecting its
own interests. 198 It may be noted that based on its 1987 Constitution there is no
distinction between archipelagic waters and internal waters while in the Convention
these two maritime zones are specifically delineated. The archipelagic waters are
constantly equated as internal waters because of the inseparable unity of land and water
domain.199 The waters adjoining land territory are regarded as the extension of the land.
Further, the waters around, between and connecting the islands of the archipelago had
always been highways of communication between the islands which brought the people
together under one sovereign state.200 They are directly within sight of a large part of the

56
population; hence, the government is expected to exercise full control over all the
activities in the archipelagic waters, particularly those undertaken by foreign vessels.201
For this reason, the management of these waters should be closer to the internal
waters regime than to territorial sea regime and the state’s protection of this maritime
zone from foreign intrusion is equated with the preservation of national integrity.202 Be
that as it may, although the archipelagic waters are regarded as internal waters, the
Philippines continue to respect and recognize traditional navigational right of innocent
passage of foreign vessels over Philippine waters in consonance with the UNCLOS.
5.2 The Philippine Archipelagic Sea Lanes Proposal
While designation of archipelagic sea lanes passage is the consequence of
acquiring archipelagic status, the Philippines has yet to submit a proposal to IMO on the
designation of archipelagic sea lanes passage. This also raised the issue of whether the
Philippines would fulfil its statements made in 1988 that it would harmonize its
domestic legislation with the provision of the Convention and that necessary steps were
being undertaken to enact legislation dealing with the establishment of archipelagic sea
lanes passage.203 Though there was a declaration, the Philippines is of the view that the
matter of designating sea lanes should be studied carefully.204 This is of such vital
concern because it critically puts into test the freedom of navigation, sovereignty over
the archipelagic waters granted by UNCLOS 1982 to the archipelagic states and the
Philippine legislations in this regard.

57
In line with this, two archipelagic sea lanes were proposed to be designated in the
country; the East-West sea lane and the North-South sea lane.205 The East-West will
traverse from Balabac Strait to Sulu Sea Junction going through Bohol Sea between
Northern Mindanao and Southern Negros Islands and the Bohol Islands then through
Surigao Strait going through Pacific Ocean. The North-South route is from Celebes Sea
going through Sibuto Passage between Sibuto Island and Simunol Island, Bongao
passing through the Sulu Sea to Mindoro Strait into the South 论文帮助/论文写作服务/负担得起我及时提交我最好的质量 – China Sea.
The straits of Balabac, Surigao between Leyte and Mindanao are normal routes
used for international navigation while the straits of Mindoro, Balabac and Sibuto
passage have to be settled because of full sovereignty exercised by the country over
these waters.206 Nonetheless, the proposed sea lanes adequately cover the usual passage
routes because the East-West route will serve the ships coming from the Malacca Strait
going to Guam, Hawaii and other destinations in the Pacific while the North-South will
serve the ships coming from the west coast of Australia and Lombok Strait going to
Taiwan, Hong Kong, Northern 论文帮助/论文写作服务/负担得起我及时提交我最好的质量 – China, Korea and Japan.207

The proposed sea lanes follow the requirements of UNCLOS specifically that
they should not deviate more than 25 nautical miles to both sides of the axis line,
provided that ships and aircraft do not navigate more than 10% of the distance closer to
the coast between the nearest points on islands bordering the sea lanes.208 This means
that the 25 nautical miles is an allowance for navigational purposes to avoid collisions of
ships and aircraft but it does not prevent the archipelagic states from prescribing shorter
distance depending on the situation.209 In this regard, the Philippines may limit the
physical extent of the archipelagic waters where the sea lanes may be designated for
safety purposes. Further, the difference provides a greater degree of flexibility in

208 Supra, footnote 192 at p. 8 209 Supra, footnote 198 at p. 109
59
protecting the coast of the islands adjacent to archipelagic sea lanes from intrusion.210 It
may also be noted from the figure above that the sea lanes would traverse in the waters
adjacent to the islands where there are existing fishing grounds. Hence, though
deliberation on the matter is being undertaken.
5.3 Issues Covering the Philippines Proposed ASLP
Based on Article 53 of the UNCLOS, archipelagic sea lanes passage should be
designated through archipelagic waters, covering all normal routes used for international
navigation and shall traverse to the adjacent territorial sea. Though the Philippine
proposal may have covered all routes normally used for international navigation, it is not
yet submitted to IMO for approval. A number of factors should be taken into account in
the event that the Philippines chose to designate archipelagic sea lanes.211 These include
the effectiveness of the government to monitor the sea lanes, security of the country,
measures to ensure safe, expeditious and continuous passage, fisheries and marine
environment, inter-island shipping and the possible connection with the Indonesian
established ASLP.
5.3.1 Legal Issues
It may be recalled that the archipelagic waters referred to under the Convention
are considered as internal waters under the 1987 Constitution. These are the waters
landward of the baselines (though in Philippine legislation they are described as waters
around, between and connecting the islands of the archipelago). Under the internal water
regime, the state enjoys absolute sovereignty and no right of innocent passage exists.212

210 Ibid. 211 Supra, footnote 35 at p. 9 212 Supra, footnote 3 at p. 61
60
This is the very essence of internal waters under the Philippine Constitution. Entry of
foreign vessels may be prohibited and they may be apprehended for intrusion. This is
where the problem would arise in designating archipelagic sea lanes passage.
There is constitutional issue in designating archipelagic sea lanes passage
because the waters within the Philippine archipelago are national or internal waters.213 In
case the archipelagic sea lanes passage is established, it follows that the status of internal
waters may be diluted or may be given two characteristics, that is, internal waters with a
strip of archipelagic waters or absolute sovereignty over internal waters can be
exercised but diluted with rights given to foreign vessels to pass the internal waters
through archipelagic sea lanes without permission of the Philippine government.
214 It
may be understood that the nature of the internal waters will be diminished because
foreign vessels could pass through in normal mode even without prior notice to the
government, thereby creating more legal issues.
Relatedly, taking into account that the Philippines (to include Cape Verde,
Dominican Republic and Maldives) has designated archipelagic baselines in a manner
not consistent with Article 47, no right of archipelagic sea lanes passage would exist
because the presence of archipelagic waters is a condition precedent to this passage.215
Considering the foregoing legal issues, it may be argued that the conflicting
regime in domestic law may delay full implementation of Part IV of UNCLOS by the
government.

5.3.2 Environmental Issues
Other than legal issues, the marine environment is also taken into account. The
government is of the view that by reason of closely knit geographical features,
navigational corridors of 50 nautical miles wide for archipelagic sea lanes passage
cannot be accommodated and in case sea lanes are designated, foreign vessels may still
deviate by passing through non-designated routes invoking their right to innocent
passage.216 The proposed routes present threats to two of the most delicate marine
biodiversity areas in the country and the world: the Tubbataha Reef, a World Heritage
Site; and the Verde Island Passage Marine Corridor which is known as a world hot spot
for marine biodiversity as well as center of shorefish biodiversity.217
Hence, in lieu of establishing archipelagic sea lanes passage, the whole country
will be designated as a Particularly Sensitive Sea Area (PSSA) 218 and associated
protective measures (APMs) will be instituted in order that security, good order and
peace may be better served.219 The APMs will be instituted to guide vessel transit in
exercise of the right of archipelagic sea lanes passage. Specific measures, like routeing
of ships can be used to control the maritime activities in the PSSA. Simply put,
designation of archipelagic sea lanes passage may not be applicable to the Philippines
because of its unique marine environmental features and geographical set up.

5.3.3 Major Maritime Security Issues
Apart from legal and environmental issues surrounding the designation of
archipelagic sea lanes passage, maritime security remains to be the primary factor with
respect to passage of vessels through archipelagic waters.220 Maritime security in the
Philippines is a key component of national security and it is specifically defined under
its National Marine Policy of 08 November 1994, as “a state wherein the country’s
marine assets, maritime practices, territorial integrity and coastal peace and order are
protected, conserved and enhanced.”221 It involves national security aspects and security
issues with regional impact.222 The former includes protection of the integrity of the
Philippine territory whereas the latter comprises illegal activities that fall within the
purview of transnational crimes and may affect neighbouring states.223 Protection of
territorial integrity is of paramount importance to Philippine defence policy which
involves addressing land based insurgencies which is a long standing security concern of
the government and maintaining physical presence to safeguard the territories in the
Philippine-occupied islands in the Spratly.224
In protecting its territory, the passage of military vessels in the Philippine waters
without prior clearance from the government poses maritime security concerns. The
government has never changed its policy of requiring prior notice of passage of warships
for purposes of proper management of the very extensive vessel traffic that takes place
daily and to avoid sources of friction.225 However, different notions of third states on the
status of Philippine waters may undermine the prior notice requirement of the

government. The United States included the Philippines and Indonesia in its Freedom of
Navigation Program 2000-2003 Operational Assertion as countries in which it can
regularly assert its freedom of navigation.226 Under this Program it conducted dozens of
routines passage through the waters of these two archipelagos. In 2000, it conducted 28
transits in the Philippine archipelago. It regarded the Philippines to have excessive
straight baselines. In June 2009 it was reported that a Chinese submarine collided with
underwater sonar array towed by destroyer USS John McCain at approximately 144
miles from Subic, potentially placing it in Mindoro Strait, Philippines.227. This indicates
that they have different interpretations on the status of the waters of the Philippines.
From the point of view of the Philippines, the baselines drawn are not excessive and are
consistent with UNCLOS.
On the other hand, the waters in southern Philippines have always been a
maritime security hot spot even before 9/11 because it is the home of Islamic separatist
groups. The location where the proposed two archipelagic sea lanes passage will be
established traverses the Sulu Sea in southern Philippines, an area of major concern to
the government. The Sulu Sea is one of the theatres of operation of the terrorist groups
Abu Sayyaf Group (ASG) and Moro International Liberation Front (MILF). There is a
still high risk of a terrorist attack in the Philippines because of the presence in the
country of these major terrorist groups that definitely have the capabilities to launch an
attack at sea. 228 The ASG which was founded in the early 1990s has proven its intent
and capability to wage maritime terrorism in the bombing of Christian missionary ship

seventeen Filipinos in Dos Palmas Resort, Palawan in May 2001 and the bombing of
Superferry 14 in February 2004 after it left Manila Bay.229
Other than ASG, the MILF which was founded in 1978 with the aim to establish
a separate Islamic state in southern Philippines through jihad has also extreme
familiarity within the maritime domain. The group always denies its involvement in
terrorist attacks in the south particularly that of Our Lady of Mediatrix in February 2000
at the bay off Mindanao which killed forty people. Despite MILF’s continuous denial of
their involvement in maritime terrorism, it has to be taken seriously because of its links
to regional terrorist organizations, such as the Indonesian terrorist group Jemaah
Islamiah (JI), which has been making plans for maritime terrorist attacks in Southeast
Asia.230
While the gruesome terrorist attacks mentioned did not transpire in the proposed
ASLP area, the ASG proved its maritime terrorist mettle and demonstrated its
capabilities of operating outside its usual maritime turf.231 The members of ASG and
MILF live very close to the waters of Basilan, Sulu and Tawi-tawi where they have
gained tremendous familiarity with the maritime environment. 232 Presently, these
terrorist groups are operating in landbases. However, seas in southern Philippines are
more vulnerable to terrorist attack because of difficulties to guard these waters. The
proposed routes for archipelagic sea lanes passage are of no exception.

It bears stressing that the discretion to designate archipelagic sea lanes remains
on the archipelagic state. Although it is not mandatory, non-designation may be
disadvantageous to the Philippines because the right of passage through these sea lanes
may be exercised through routes used for international navigation and the state cannot
monitor and regulate the passage of foreign vessels.233 The advantage to the Philippines
if it designates sea lanes is that the routes over which vessels can exercise archipelagic
sea lanes passage will become clear and monitoring of traffic therein for possible vesselsource pollution will be better implemented.
In the light of the preceding discussions, the Philippines recognizes the
significance of archipelagic sea lanes passage. Once the sea lanes are designated,
uncontrolled navigation over its waters will be prevented. Vessels shall respect the
designated sea lanes and corresponding traffic separation scheme based on Article
53(11). However, it is carefully balancing the interest between the third states with its
own interest as the possessor of jurisdictional rights over its waters. It may revisit its
position with regard to designation of archipelagic sea lanes passage following the
newly enacted Baseline Law, RA 9522, but the paramount importance of security of its
waters will be considered.

CHAPTER VI

MARITIME SECURITY CHALLENGES
The Philippines and Indonesia may have different perspectives with regard to the
establishment of archipelagic sea lanes passage. Indonesia preferred to designate these
sea lanes to fully acquire archipelagic status while the Philippines chose to withhold the
designation to assess carefully the needs of the user states and the concerns of the
country. However, both states have common interests in protecting the archipelagic sea
lanes from unlawful interference because such sea lanes traverse the archipelagic waters
and the adjacent territorial sea. This implies direct access to the archipelagic domain
right around the perimeter.234 Any incident that may happen on the archipelagic sea
lanes passage will have direct effect on the archipelagic state concerned because it is
within its maritime jurisdiction. The nature of archipelagic sea lanes passage is exposed
to maritime security challenges be it maritime crimes or foreign intrusion.
Maritime security can be defined as those “measures employed by owners,

land and air targets because the terrorist should possess a high degree of skills and
capabilities in executing the attack. However, seas are apparently more vulnerable to
terrorist attacks because of embedded difficulty to guard the waters.237 The Philippines
and Indonesia contribute 24 and 59 percent, respectively; to the total 92,451 km
coastline of Southeast Asian region.238 This situation raises the concern of these two
world’s largest archipelagos over their respective maritime zones and sea lanes used for
international navigation even higher. The figure below illustrates the important routes
for international navigation between Indonesia and the Philippines.

6.1 Facing Maritime Threats
The attack against US Navy Destroyer, USS Cole in the port of Aden in 2000 and
that of French oil tanker Limburg in the coast of Yemen in 2002 have made the terrorist
statements clear that they can penetrate the force protection and they can affect world
commerce.239 The Limburg attack raised concerns over the possibility that terrorists in
the Southeast Asian region might attempt a maritime terrorist attack in the Straits of
Malacca.240 The latter is the shortest route between Middle East and the ever growing
Asian market with an estimated 15 million bbl/d flow in 2006. 241 In recent years,
international interest in maritime security has been focused on Malacca and Singapore
Straits but shipping in the Indonesian archipelago, particularly through Lombok and
Makassar Straits is potentially vulnerable to attacks.242 These straits constitute ASL II
and similar to other established archipelagic sea lanes passage in Indonesia, they serve
as primary shipping lanes for Australian international commercial navigation. In 2004–
05, freight carried via the ASL constituted 39 per cent of Australia’s exports by value
(50 per cent by weight) and 32 per cent of imports by value (41 per cent by weight). 243

It may be noted from the tables above that a significant number of vessels
relating to Australian international trade pass through the established archipelagic sea
lanes. Although the data reflect only the utilization by Australia of the sea lanes, these
shipping routes are important to the world’s sea borne trade between the Indian Ocean
and the Pacific Ocean. These particular sea lanes have not been included in scenarios
where possible terrorist attacks could take place. However, their susceptibility to
maritime threats cannot be ignored.
6.1.1 Maritime Terrorism
One of the threats is maritime terrorism. Any disruption caused by the blocking
of passage due to this maritime security threat would result in great economic loss for
the user states. Taking Australia as an example, its reliance on Indonesian ASLs
constitutes a significant percentage of its seaborne trade. Any unplanned disruption of
sea lines of communications between Australia and the rest of the world could devastate
the country’s national economy.244 This also impacts upon the archipelagic state because
the passage traverses within its maritime zones.
The main terrorist organization operating not only in Indonesia but also in the
larger part of Southeast Asia that has capability of launching attacks be it in the sea or on
land is Jemaah Islamiya (JI). It is labelled as Al-Qaeda in Southeast Asia that promotes
the idea of establishing an Islamic Caliphate in the region around Indonesia, Malaysia,
Singapore, southern Philippines and southern Thailand.
245 JI is known for its hideous
terrorism activities particularly the Bali attack on October 2002 that claimed
approximately 200 lives. The seaborne capabilities of its key operatives and its notorious
history of planning suicide missions to attack American naval warships passing through

244 Supra, footnote 26 at p. 2 245Supra, footnote 229 at p. 255
71
Malacca Strait in 2001 as well as vessels visiting Changi Naval Base in Singapore make
JI as a real threat to maritime security.246
On the other hand, maritime terrorism also affects the waters of the Sulu Sea
where the proposed north-south and east-west routes of archipelagic sea lanes will
traverse. This is undertaken by extremists groups ASG and MILF. They have records of
linkages with JI which started in Afghanistan in 1980s.247 MILF protects JI members by
providing training facilities for over a decade and key JI fugitives from Indonesia and
Malaysia join ASG.
248 The members of ASG and JI joined together in July 2005 for
underwater training in Sandakan, Malaysia in preparation for attacking maritime
targets. 249 They routinely move between Sabah, Borneo and their training camps in
Mindanao by speedboat, local craft and ferries. 250 This alliance of terrorist groups shows
their capabilities. They are well equipped, well trained and their styles of attacks vary
which makes future terror activities even harder to predict. This is also an indication that
these terrorist groups may have begun to look at the maritime domain as a new avenue
for attacks.
6.1.2 Piracy and Maritime Terrorism
Piracy is another great concern for these two states on their waters. Based on the
reports of ReCAAP and IMB, as pointed out in Chapter IV, piracy and armed robbery
exist in Natuna waters where Indonesian ASL I traverses. It is also worth mentioning
that Indonesian waters continue to be included on the IMB list of piracy prone areas in

246 Ibid. 247 International Crisis Group, Southern Philippines Backgrounder, Asia Report No. 80 2004
https://monkessays.com/write-my-essay/crisisgroup.org 12 July 2010 248 Ibid. 249 Supra, footnote 229 at p. 258 250 Sam Bateman, Assessing the Threat of Maritime Terrorism: Issues for the Asia-Pacific Region,
Security Challenges Vol. 2 Number 3 2006 at p82 https://monkessays.com/write-my-essay/securitychallenges.org.au 12 July 2010
72
Southeast Asia. From 2005 to March 2010, IMB recorded a total of 57 piratical and
armed robbery attacks in the waters of Indonesia compared to 7 attacks in the Malacca
Strait in the same period (see Annex 5). The drop in number of piratical attacks in the
Malacca Strait is attributed to the aggressive patrol of littoral states since 2005 but it
remains to be in the IMB list of piracy prone area according to ICC-IMB Report First
Quarter 2010.
While piracy is also reported in ports and anchorages and regarded as largely a
criminal issue, it has become a serious security issue by reason of its potential
connection with maritime terrorism.251 It is given that piracy is different from terrorism
considering that the former is motivated by private ends while the latter is rooted in
political or religious ideology. However, possible cooperation between terrorists and
pirates poses a huge risk.252 The indications that piracy is used as a means of funding
terrorism activities are conclusive in the case of Southern Philippines.253 Members of
MILF and ASG use piracy mainly as a means of fund raising.254 These extremists have
been accused of conducting piratical attacks in Sulu and Sulawesi as a means of
generating income for their causes.255 The vast majority of maritime depredations in
these areas have gone unreported to the IMB because it only receives reports in English
via high frequency radio or fax, and language skills and equipment are often lacking. 256
Also, the masters of the vessels prefer not to report the incidents even to local authorities
for fear of another attack. Maritime violence in this area has so far been more serious in
terms of human suffering.257

73
Seemingly, the international attention on maritime violence remains focused on
the Straits of Malacca because of its importance as a major international sea lane with
over 50,000 vessels258 transiting per year and an attack in this area would have a great
consequence to the global economy259. However, if maritime terrorism and piracy are
placing Malacca Straits or any other sea lines of communication in great danger, these
maritime threats also place the archipelagic sea lanes in great danger which will
prejudice global maritime trade and specifically the security of the archipelagic state.
6.2 Securing Maritime Domain
The issue of passage of military vessels has been the heart of the archipelagic
problem and is likely to remain a source of controversy.260 The primary military concern
of third states is the maintenance of their navigational rights within archipelagic waters
which makes the regime a highly politicized problem. 261 There are differing
interpretations of user state and archipelagic state on various issues surrounding the right
of archipelagic sea lanes passage of military vessels and aircrafts.
“normal mode”
The term “normal mode” in Article 53 (3) provides an undetermined range of
activities for warships navigating archipelagic waters which are not permitted in the case
of innocent passage in territorial seas.262 The meaning of “normal mode” is not given in
UNCLOS 1982.263 From the context and from the negotiating history, the term was

258Supra, footnote 241 259 Supra, footnote 230 at p. 64 260 Supra, footnote 8 at p. 162 261 Supra, footnote 13 at p. 24 262 Supra, footnote 179 at p. 97 263 Supra ,footnote 21 at p. 342
74
intended to refer to that mode which is normal or usual for navigation by a particular
type of ship or aircraft making the passage; hence, the employment of radar, sonar and
depth finding devises would be included if they are normally used in navigation.264 The
term could also include submerged transit, maintenance of ship formation, continuous
operation of naval surveillance and monitoring equipment, constant weapon readiness
and aircraft launch and recovery. 265
Under Article 39(c), warships navigating in normal mode shall refrain from any
activities other than those incident to their normal modes of continuous and expeditious
transit except in cases of force majeure or by distress. This means that they are not
permitted to engage in any other activities like conducting war game exercises, making
covert transmission or hydrographic surveys. Otherwise, navigating in normal mode
would be contrary to continuous and expeditious passage required by Article 53(3)
which are the obligations that fall on the transiting ships or aircraft in archipelagic sea
lanes passage.266 Also, this may bring the situation where the archipelagic sea lanes
would be considered as a playground of foreign warships which is not favourable to
archipelagic states.
“connecting parts of the high sea”
Relatedly, the fact that archipelagic sea lanes passage may further proceed
through territorial sea can be interpreted in a broad sense, as connecting parts of the high
seas or exclusive economic zone.267 The user states construe sea lanes as extensions of
the high seas or EEZ while the archipelagic states regard them only as a link between
one part of the high seas or EEZ and another part of the high seas or an EEZ. In

264 Ibid. 265 Supra, footnote 179 at. p 97 266 Supra, footnote 21 at p. 477 267 Supra, footnote 13 at p. 27
75
asserting their respective rights, the former would always maintain freedom of
navigation while the latter would claim sovereignty over the archipelagic waters
pursuant to Article 49(4).
In the reported incident mentioned in the preceding Chapter involving a US
destroyer and Chinese submarine, the states concerned claimed that they were in
international waters. It may be noted that the location points to Mindoro Strait, one of
the routes proposed as north-south archipelagic sea lanes. While Philippine government
did not file a diplomatic protest with either the US or 论文帮助/论文写作服务/负担得起我及时提交我最好的质量 – China and chose not to commence
a political discussion on the issue, this has caused uproar among civil society. The
incident was regarded as one of the many unnoticed intrusions in the Philippine
archipelago because of its vast maritime space and extremely limited surveillance
capability. A similar case took place in Indonesia as mentioned in Chapter IV which
prompted the citizens to push the government to regularize a single east-west route
through Java Sea.
In the case that the warships mentioned or any other foreign warships are
exercising the right of archipelagic sea lanes passage in that particular route, the
UNCLOS 1982 requires that the act of passing should be continuous; vessels shall
proceed without delay and shall not cause any threat to the security of the archipelagic
state. In case of an aircraft, the right of overflight is restricted to air routes above sea
lanes which preclude its application to overflight above land territory.268 It is important
for foreign warships or aircraft to proceed without delay through these sea lanes to
prevent any notion of performing other activities prejudicial to the security of the
archipelagic state. Hence, archipelagic sea lanes passage means no-stopping passage
where there should be no activities may be conducted.
Both the Philippines and Indonesia prefer prior notice of passage of warships
because the mere presence of military vessels within the archipelagic waters if there is

268 Ibid.
76
no military exercise raises a security issue. Indonesia requires prior notification for
warships entering its territorial sea.269 This may not be convenient for the user states on
the grounds that it hampers the continuous and expeditious passage. However, this
requirement is designed to prevent any surprise to naval forces securing the waters,
which may create other issues between third states and the archipelagic state. In practice,
both states recognize the navigational right of third states over their archipelagic waters
wherein even statements of excessive claims are oftentimes tolerated. They further allow
foreign warships to pass through the routes normally used for international navigation.
“level of jurisdiction”
Emphases should also be made on the level of jurisdiction that the archipelagic
state may exercise over the vessel exercising the right of archipelagic sea lanes passage.
It bears stressing that Article 42 applies mutadis mutandis to archipelagic sea lanes
passage. It provides that the application of laws and regulations shall not have a practical
effect of denying, hampering or impairing the right of passage. In this regard, the level
of jurisdiction is prescriptive only.270 This level of jurisdiction allows a coastal state to
require ship’s compliance with safety rules, fishing, pollution control and customs
laws.271 Ships may not be inspected, arrested, detained, refused passage or subjected to
other forms of control that would impair the right of passage.272 In this regard, the
archipelagic state could only exercise its enforcement jurisdiction to the full extent in
case the ship would voluntarily enter the state’s ports or in some other way comes within
the state’s competence to totally exercise its enforcement jurisdiction.273 Nonetheless,

2010
270 Supra, footnote 21 at p. 377 271 Supra, footnote 24 at p. 34 272 Supra, footnote 21 at p. 377 273 Ibid.
77
these restrictions should not affect the right of the archipelagic state to board a particular
vessel passing through the sea lanes based on reasonable suspicions that it is engaged in
piracy or in unlawful acts or is a ship without flag.
It is given that the right is non-suspendable under any circumstances and that
passage of foreign warships in normal mode cannot be impeded. However, by reason of
this limited jurisdiction, the archipelagic state may exercise other options for the sake of
its self preservation in the event it is confronted with serious maritime security issues
caused by vessels exercising the right. It may be recalled that there were times
particularly in 1988 where Indonesia closed or attempted to close some of its straits and
in 1992 it questioned the passage rights of an Australian submarine navigating through
Sunda Strait.274 These situations indicate that the archipelagic state would implement
necessary measures to ensure that its national interest is adequately protected.
6.3 Advantages of Archipelagic Sea Lanes Passage

As the seaborne trade flows into and within the Asia-Pacific region increase, the
reliance on the sea as a mode of transport also increases.275 This development makes the
security of sea lanes even more crucial as they are considered major arteries from which
the wealth of regional economic progress will spread.276 It is important that navigation
of commercial shipping in Southeast Asia should be free and safe despite of the
challenges.
One of the advantages of designating sea lanes is the proper monitoring of vessel
traffic on routes normally used for international navigation. Once sea lanes are
designated, foreign vessels, particularly warships, are confined to exercise the right of

274 Supra, footnote 23 at p. 330 275 Josua Ho, The Security of Sea Lanes in Southeast Asia, Military Technology Academic Research
Library 2005 at p. 14 https://monkessays.com/write-my-essay/apcss.org 25 June 2010 276 Ibid.
78
passage through designated archipelagic sea lanes and can only exercise innocent
passage through the remaining archipelagic waters.277 This will prevent warships from
navigating within any part of the state’s maritime zones and further claim that they are
exercising the right, thereby indiscriminately opening the whole archipelago to
archipelagic sea lanes passage. It facilitates the transport of seaborne trade because
foreign commercial vessels would traverse the shortest international route in a
continuous and expeditious manner. For Indonesia, the designation enhanced the safety
of navigation, protection of the environment and also the security of maritime domain.278
With regard to designation of east-west passage, it requires thorough deliberation to
ensure safety of passage and the marine environment and that the security of Indonesia
would be safeguarded.279
On the other hand, the Philippines is aware that the sea lanes are the lifeline of
the region and securing them provides unhampered access to markets and investment
opportunities on economies within the region.280 Notwithstanding the restrictive nature
of passage regime in archipelagic waters, it may be proper and advantageous for the
country to use the designation as a means of maintaining a relationship with the
international community particularly the user states traversing its waters.281
In case the Philippines decides to push through with the designation of
archipelagic sea lanes following the enactment of the new baseline law, the country may
consider designating a minimum number and only the major routes used for
international navigation should be covered for purposes of archipelagic sea lanes

passage.282 In any case that these normal routes accommodate the interests of the major
user states, the Philippines may choose to enter into bilateral agreements with, e.g., the
US for its naval interest and Australia for its commercial interest.283 Considering the
importance of protecting environmentally sensitive areas, it would also be in the interest
of the country to limit the passage by certain types of vessels with special types of cargo
through certain sea lanes.284 The government may also prescribe the areas to be avoided
or provide a traffic separation scheme in case the route would traverse a declared
PSSA285 as long as it would not impede the passage. This would ensure the safety of
navigation through the designated sea lanes as well as protect the marine environment
and its maritime security.
The designation of archipelagic sea lanes carries with it the obligation to keep
them safe. Both states should focus on capability building measures whether at the
national level or regional level to ensure the safety of navigation. Cooperation between
the governments of Indonesia and the Philippines for the possible connection of ASL II
and the projected north-south route should be studied in order to safeguard the passage.
Continuous coordination is necessary to overcome the challenges of maritime security
along the sea lanes as well as the entire maritime domain.

CHAPTER VII
CONCLUSION
It is worth noting that maritime security challenges related to archipelagic sea
lanes passage being faced by the Philippines and Indonesia encompass general concerns
for the security of the maritime domain and crimes that may be committed through the
use of the sea. Differing interpretations on the status of passage create security issues.
Maritime crimes such as piracy, maritime terrorism and armed robbery against ships in
the maritime domain are among the factors that have a potentially great impact to sea
lanes be they archipelagic sea lanes or routes or straits used for international navigation.
Notwithstanding, both states are conscious of the interests of maritime powers with
regard to strategic and economic dependence on the passage through the archipelagos.
Both continue to protect the needs of the user states by implementing measures to keep
the shipping lanes free from obstruction.
In this regard, the claims of the archipelagic states, the Philippines and Indonesia,
for special regimes and for recognition as single entities cannot be construed as mere
claims to extend maritime jurisdiction. 286 They are not plain eager assertions of
sovereign control over the waters connecting the islands of the archipelago. It is
extremely important for these states to preserve territorial integrity which serve as a
stepping stone to economic development. The specialized regime of archipelagic sea
lanes passage was negotiated in the hope that this scheme would achieve a balance

286 Supra, footnote 18 at p. 45
81
between the rights of navigation of third states and the archipelagic states’ respective
national interests.
In exercising the option given by UNCLOS 1982 under Article 53, the
archipelagic states may evaluate the advantages and disadvantages this designation
might bring in the exercise of sovereignty over their maritime zones. In the case of
Indonesia, as the first state to designate archipelagic sea lanes, it considers the move as a
step closer to implementing its rights over its waters although the designation was held
by the IMO as “partial designation”. The issue of “partial designation” creates
controversy to the user states but as far as Indonesia is concerned, it has carried out its
responsibility to the international community. The Philippines, on the other hand,
determined that this matter should be carefully weighed in light of new developments in
maritime security before it could finally implement Article 53. Be that as it may, it is
important that the legislations to be adopted in this regard be consistent with UNCLOS
and that the state practice should uphold overall interests.
The regime brings both advantages and disadvantages. It facilitates transport of
seaborne trade and movement of military vessels while the state that designated the same
is able to properly monitor vessel traffic on routes normally used for international
navigation. On the other hand, the disadvantages to the archipelagic state are the nonsuspendable feature of the right and the limited jurisdiction that may be exercised upon
the vessel. It is true that freedom of navigation remains a residual fundamental freedom
which can be limited only when the need to do so is demonstrated. 287 However,
measures by archipelagic states such as coastal monitoring/surveillance or boarding of
suspect vessels might be justified in cases where the activities of foreign vessels affect
the security of the archipelagic sea lanes or the maritime domain in general. Foreign
warships and commercial vessels might consider these measures as obstructions to

287 Supra, footnote 4
82
continuous navigation. Nevertheless, preventive measures should not be interpreted as
encroachments on passage rights but should be viewed as initiatives advantageous to
both user states and archipelagic states.
The principle introduced by Grotius does not mean freedom to navigate in
accordance with the domestic laws of the flag state alone but should be understood as
navigation, trade and commerce within the framework of international law. Hence, the
responsibility must be shared between the user states and the archipelagic state.
Balancing of interests, which is the very purpose of introducing this specialized regime,
involves careful consideration of the concerns of both sides and continuous
reconciliation of the interests involved.
