Introduction
The North Sea a treasure
of rich resources hosting a route of immense strategic, economic and political
essence has been a point of disputes since medieval periods. Encompassing
continental shelf claims of six powerful states including France, Belgium, United
Kingdom, Netherlands, Norway and Germany it is the water body located off the
coast of Northern and Western Europe. With the development of the conceptual idea of maritime
boundary providing division of marine natural resources, such as oil and
fish, delimitation disputes have started becoming relatively common. Each state
is motivated to claim to control a larger part of continental shelf vesting
exclusive rights as to resource extraction to its state stretching up to 350
nautical miles from the baseline[1].
Occurrence of inter-state disputes apportioning maritime boundaries,
supranational bodies like the “International Court of Justice” (ICJ) would have
the authority to balance treaty obligations, precedent, and equity.
The North Sea Continental Shelf Case had
laid a landmark judgment in deciding disputes entailing delamination
process. The dispute of the instant case was brought before the court on
February 20th, 1967 concerning the boundaries of the
continental shelf in the North Sea present between Netherlands, Germany and Denmark
respectively. Parties to this case had duly requested the ICJ to constructively
assess the rules and principles of international law thereby agreeing to
implement the delimitations thus stated. The dispute makes its inception
from the disagreement towards sea boundary limitations that were previously
decided between the party nations. This non alignment necessitated the Court to
determine as to whether the parties were bound by the treaty or customary
international law to uphold the ideals that they had espoused.
Facts and Contentions
The present dispute involves
claim over a North Sea continental shelf by three states Netherlands,
Demark and Germany with both Netherlands and Denmark instituting
individual cases against Germany before the ICJ. This act was based of two
individual special agreements entered on 1st December, 1964 between Germany
and Netherlands, and another on 9th June, 1965 between the Federal
Republic and Denmark[2] in
order to decide the applicability of international provisions in case of any
dispute. However, the ICJ decided to club both the claims thereby issuing
a single ruling. It was also corresponded by the parties to the case that the
ICJ would not physically assign claims, but to only prescribe a delimitation method
for the parties to follow.
At the heart of this dispute lie the
diverse geographical locations of the three states in the shallow North Sea's
waters with less than 200 meters of continental shelf making up the whole
seabed aside from the Norwegian Trough, with majority of it had already been
agreed upon by the relevant coastal states[3].
Denmark and the Netherlands entail convex boarders opposed to concave boarder
of Germany. The duo party nations proposed to abide by the “equidistant”
principle meaning that a line would be drawn thereby dividing equal distance to
all the states closest to them claiming that it was a, general norm of conventional
practicality, besides being a priori and customary international rule of law
under ‘Article 6’ of Geneva Convention on Continental Shelf.[4]
Opposing this proposed principle and
denying its obligatory nature, Germany contented that the nation was merely a
signatory but had not ratified the Geneva Conventions thus making her an
exception. Asserting that the equidistance approach would result in a smaller
area for it on the continental shelf, it contended that the method was grossly
unjustified. Germany thus argued for shelf apportionment with respect to the proportion
of its coastline along the North Sea thus proposing delimitation based on
equivalent distribution principle. Thus, the main
contention in this case was regarding the delimitation of the continental shelf
so as to provide a ‘just and equitable share’ to all three states.
The researchers with the
aid of the diagram would like to showcase the earlier and onboard issues that
resulted in the case as follows. Based upon the equidistant principle, Denmark
and Netherlands had drawn partial boundary lines jotted as A-B and C-D
respectively. Further prolongation of these boundaries (B-E and D-E) were
posing challenges since there was no consensus being arrived at by the three
states with Germany opposing the equidistance principle addressing its
contentions of inequitable
outcomes[5].

Issue
Identification
Legal
issues presented before the International Court of Justice in the instant case
are as follows:
1.
Whether Germany is legally obligated to accept equidistant
principle under ‘Article 6’ of the ‘Geneva Convention on the Continental Shelf,
1958’ law as a customary international rule?
2.
What aspects lay the basis for construction of an
international customary rule of law?
3.
Whether Geneva Convention is enforceable against a state that
has not ratified it?
4.
Whether the rule of Equidistance is recognized and
enforceable by the international law?
5.
What principles and rules are applicable to the delimitation
dispute of continental shelf that shall ensure equitable and justified division
under international law?
Rule
Statement
The court primarily examined the
concept of “continental shelf” thereby further progressing towards analyzing
the justified method of delimitation rule to be adopted. The court examined ‘Article
6’ of the ‘Geneva Continental Shelf Convention, 1958’ encapsulating the
Principle of Equidistance[6]
besides analyzing Articles 1 to 3 addressing the foundational concept of ta continental
shelf. Additionally, the court has relied on the 1945 Truman Proclamation which
is the first decision passed attributing a continental shelf legal
jurisdiction. In order to critically examine various rules and principles under
international law judges Sorensen and Tanaka have relied on ‘Article 38’ of the
International Court of Justice[7].The
method of equidistance outlined in “Article 6 of the Geneva Convention”,
applies to continental shelf delimitation unless parties agree otherwise or
special circumstances exist. It has also been analyzed by the court that Customary
International Law can create obligations for states, even if they haven't
signed relevant treaties. To be considered customary law, a rule requires:
·
Generality:
Widespread and representative participation by states, particularly those with
a specific interest (coastal states in this case).
·
Uniformity:
Consistent and uniform state practice over time.
·
Opinio Juris:
A general recognition by states that the practice is obligatory under law.
With the aim to critically analyze the
relevant principles under customary international law, a few judges, including
Justice Tanaka and Justice Sorensen, specifically referenced Article 38 of the
International Court of Justice.
Analysis
The researchers shall proceed with
critical analysis of the present case by drawing correlation between the legal
rules as well as provisions with the pertinent facts of the case.
v Emergence of Legal Concept of a Continental Shelf
The section
of a continental landmass that is immersed in a relatively shallow layer of
water is called a “continental shelf. The.
Abundance of wealth in the continental shelve’s reserves encapsulating vast
fishing grounds and oil and gas resources became apparent, the necessity for a
legal status for these areas was acknowledged.[8] The
first attempt to establish jurisdiction over continental shelves was the Truman
Proclamation of 1945, which acknowledged American exclusive jurisdiction over
its assets on the continental shelf.[9] The ICJ
issued a judgement in the North Sea Continental Shelf case, a dispute amidst “Germany,
Denmark, and the Netherlands” regarding the continental shelf’s delamination in
the North Sea. This analysis will focus on the legal principles applied by the
Court and their applicability to the case. The Court first examined whether ‘Geneva
Convention on the Continental Shelf” the would be applicable to the present
delimitation. It was determined that the state of Germany had failed to ratified
the convention, thereby rendering it not bound by the convention’s provisions,
specifically “Article 6” outlining the equidistance principle for delimitation.
Figure 1 - Provisional equidistance
lines in the North Sea.
The Court
further deliberated that whether or not all states were required to
abide by the equidistance standard as a customary international law rule.
States, "Denmark and the Netherlands" contended that the notion was
ingrained in the idea of the continent's shelf and had evolved into official
state policy. The Court disagreed. It found that the
equidistance principle was not universally accepted nor consistently practiced
by states, and “Article 6 of the Convention” allowed for reservations,
suggesting it wasn't seen as a pre-existing customary rule.
v Applicable
Law and Delimitation Process
Since
neither the Convention nor customary law mandated the equidistance principle,
the Court turned to the broader legal framework for delimitation. It found the
core principles stemmed from the Truman Proclamation of 1945, which established
the rights of a coastal state with regards to the continental shelf and emphasized
delimitation by agreement based on equitable principles. The Proclamation
further specified that delimitation would be decided "in accordance with
equitable principles" in situations where neighboring states disagreed
about the continental shelf. Due to the numerous issues raised by this
declaration, the “Geneva Convention on the Continental Shelf” was created in
1958.[10]
v Position of “Article 6 as a Customary Law”
during the Convention's formation
The
nations of Netherlands and Denmark additionally contended that the Convention's
establishment or the following actions of the member states have given rise to
the equidistance concept of equidistance as a general rule of customary law. In
response, the Court noted that insufficient admission s and ratifications to
the Convention suggested that the principle was not widely acknowledged or
widely practiced[11].
Regarding the temporal component, the Court decided that, given the development
of customary law, a shorter period would not be inadmissible; however, the rule
in question should be applied broadly and consistently.[12] The
few states who did not ratify the Convention did not demonstrate that they were
abiding by any rule established by customary international law; rather, their
intentions were wholly hypothetical. As a result, there was no clear opinion “juris
sive necessitatis”, which is the conviction that an activity is carried out
as a legal obligation that is established in response to the satisfaction of
two requirements.[13]
The first requirement is that the state's actions must amount to a
"settled practice," and the second is that the states must think they
are abiding by the law and not doing so out of courtesy, custom, habit, or
convenience. The Court emphasized the concept of “opinion juris" by
citing the seminal decision of S. S. Lotus case[14]. The
Court determined that during the period of drafting the convention, customary
international law was not in existence and did not include the equidistance
norm found in Article 6. The International Law Commission (hereinafter referred
to as ILC), that had drafted the Convention, indicated reluctance to include
Article 6 additionally, permitting reservations to Article 6. These arguments
were used by the Court to support its conclusion.
v Applicability of Customary International Laws on Equidistance Principle
Despite the Court's ruling that Germany’s failure
to ratify the CCS rendered Article 6 of the Convention unenforceable,
Netherlands and Denmark asserted that the principle of equidistance would
remain valid due to its reflection of customary international law, making it
automatically binding on all states, regardless of the Convention. The Court
made clear that the goal of delimitation was to recognize each state's natural
extension of its land area beneath the sea, not to assign regions. Though
practical, the equidistance approach could result in territory being assigned
to a state that was not a natural extension of its landmass, which could lead
to unfair outcomes. Germany argued it was not bound by
Article 6 as it had not ratified the Convention. The Court agreed. It rejected
arguments that Germany had assumed obligations through unilateral actions or
was bound by estoppel. The Court reasoned that a state's conduct would only be
binding if it demonstrated a "very definite very consistent course of
conduct" indicating an intention to be bound by a treaty it had not
formally ratified.
Figure 2 - Claim lines of Germany, Netherlands and Denamrk
Further, the court also asserted that
the principle of equidistance did not meet the criteria for customary
international law since, as per Generality: The Convention had a limited
number of ratifications at the time. Secondly the aspect of Uniformity: While
some states used the equidistance method, practice was not universally
consistent and lastly Opinio Juris: The Court concluded there was not enough proof that
states that used the equidistance method did so because they were obligated by
law.
v Customary International Law and
Treaties
The individual actions
against Germany launched by the Netherlands and Denmark were consolidated by ICJ
wherein each nation possessed claims to the continental shelf in the north sea.
However, the 1958 Convention was not ratified by Germany, which included a specific method
(equidistance) for dividing these underwater territories. The Court ruled that
Germany wasn't obligated to follow this method since they weren't part of the
agreement. Denmark and the Netherlands couldn't force Germany to use it. The
Court explained that for an unsigned treaty provision to become widely accepted
in international law, there needs to be broad participation by many countries,
and they must act as if following the rule is a legal requirement. In this
case, not enough countries had signed the Convention that had not been in
effect for long enough 11 years to meet this standard. An additional wrinkle
was the shape of Germany's coastline. If a simple equidistance method were
used, it could give them an unfair advantage. The Court encouraged all sides to
consider this when negotiating a new boundary.
v The Impact / Influence
The Court in its conclusion had determined
that the equidistance principle was not ‘priori’ meaning a customary rule of international
law as had been claimed. Instead, it was to be viewed as one delimitation
choice among several for the establishment of just maritime borders. Germany
argued that states should not be allowed to claim “the natural prolongation of
their continental shelf” if apportionment was not done in a way that made the
size of a claim proportionate to a state's coastline. However, this argument
was also rejected by the court. Rather, the Court suggested that delimitation
be carried out using "equitable principles," which would take into
consideration a number of variables to guarantee that each state received an
equitable share of the disputed claim. On January 28, 1971, Germany signed
agreements with Denmark and the Netherlands to settle the dispute over North
Sea continental shelf in response to the ruling of the court[15]. Since
the UK's existing borders were based on the endpoints of the previous equidistance-based
boundaries between Denmark and the Netherlands, these agreements forced the UK
to modify the endpoints of its continental shelf boundaries with Netherlands
and Denmark thereby creating a completely new continental shelf boundary with
Germany.
v Key Findings and Applicable Law
- The ‘Geneva Convention on the Continental
Shelf, 1958’ would not apply to Germany as the state had not ratified it.
- The principle of equidistance enriched
under ‘article 6’ is not a obligatory customary international rule.
- Delimitation of continental
shelf must be on the basis of an agreement between states based on
equitable principles.
- Primary goal is to leave each
state with the areas that institute the natural prolongation of its
territory.
- Factors to consider during
negotiations include:
o
Coastline
configuration and presence of special features
o
Geological
and physical arrangement of the continental shelf
o
Proportionality
between shelf area and coastline length
o
The region's current delimitations of the continental shelf
Conclusion
Conclusively, the researchers agree
with Justice Tanaka's assessment that the Court erred in concluding that
customary international law does not apply to the equal-distance standards that
have been detailed in ‘Article 6’ of the convention. The ‘Truman Proclamation’
in 1945 had established the continental shelf’s concept. Further, the 1958
international treaty that embraced it, was signed just fifteen months later, with
both barely being mentioned by the Court.[16]
The Court ought to have adopted a less formalistic and more expansive viewpoint
in light of society's dynamic nature, particularly in the late 20th century. Although
the Court made progress in eliminating the period of time that custom emerged,
they were unable to see the necessity of establishing unambiguous legal
principles as opposed to equitable or grounds-based principles. Since then, the methodology used in this
decision has been changed.[17]An
analogous principle to the equidistance principle established in ‘Article 6’ of
the 1958 convention was later enriched under Article 15 of the 1982 Convention.[18] The case
of “Bahrain v. Qatar” decision, decided in 2001, recognized that, generally
speaking, customary international law recognizes Article 15 as the special circumstances
concept[19].
The Court further stressed that
equality should only be used as a guide for implementing delimitation, not as a
means of doing so. A similar ruling was
made in the 2006 arbitration case of “Barbados v. Trinidad and Tobago”, where
the court determined that the delimitation should be implemented through a
two-step procedure. Initially, a provisional demarcation based on the
equidistance principle should be carried out, and then this line should be
adjusted in accordance with the pertinent circumstances that are case-specific so
as to achieve an equitable outcome.[20]
All aspects being critically considered, the ICJ’s decision in the present case
remains a landmark decision in the sphere of international law as it effectively
addresses the manner in which treaties and agreements become part of the body
of international law. The Court's decision of upholding equidistance
delimitation practice which was not always customary in international law was
equally significant. Although equidistance delimitation is still frequently
used, the Court's preference for equity over equidistance established a new
standard for boundary negotiations starting in 1969.This case established
important precedents for future continental shelf delimitation disputes. It
clarified that the equidistance principle is not a universally applicable rule
and emphasized the importance of equitable principles and natural prolongation
in determining boundaries. The factors outlined by the Court continue to be
used in negotiations and arbitrations on continental shelf delimitation. The
specific findings concerning the convention and customary law apply directly to
the present case involving Netherlands, Denmark, and Germany. However, the
broader principles of equitable delimitation and natural prolongation have
become influential in subsequent cases dealing with continental shelf
boundaries.
Reversed Judgment
The judgment delivered by the ICJ in
the present North Sea Continental Shelf Case is determined to be a landmark
order that dealt with the concept of supranational delimitation for the very
first time. However, aligning with the requisite guidelines mentioned, the
researchers have critically analyzed few ounces including potential counter
arguments and interpretation of relevant facts and rules thereby asserting the
prospective of an alternate judgment favoring the other party that had
succumbed to the judgment passed. The original judgment upheld the equidistance
principle enriched under ‘Article 6’ of the Geneva Convention on Continental
Shelf while addressing necessary adjustments for Germany's specific concave
coastline.
The equidistance principle though
emphasized as the main technique for delimitation in the ILC commentary on the
Geneva Convention of Continental Shelf, asserts deviations to be made only in
"special circumstances[21].”
According to UNCLOS Article 76, the existence of islands might lead to unique
situations when defining maritime boundaries. The International Court of
Justice (ICJ) took into account the geographical features, such as islands,
when establishing maritime borders in “Qatar v. Bahrain[22]” maritime
delimitation case. Additionally in case of “Libya v. Malta[23]”
Continental Shelf decision recognizing the limitations of the equidistance
concept the court stressed the significance of taking into account pertinent
topographical, geological, and geomorphological criteria in addition to
equitable considerations.
The geographical aspects including
the presence of Shetland, Frisian, Orkney Islands and archipelagos restrict
fair division of continental shelf due to the concave shape of the territorial
boarder of Germany opposed to the common convex shape of Netherlands and
Denmark. This geographical difference halts the Federal Republic nation from
exercising equal rights thereby rendering very less area of continental shelf
as opposed to other nations thereby falling under the ambit of special
circumstances justifying a departure from equidistance as held in “Cameroon v.
Nigeria Case[24]”. Additionally,
counterarguments against the original case could include arguments for a
boundary that reflects their coastline projection by invoking the equitable principles
outlined under ‘Article 5’ of the Geneva Convention. As per ‘Article 6’ of the
Geneva Convention on Continental Shelf, in cases where two or more States have
coastlines that face each other and their continental shelf is adjacent to
their territories, the states shall agree on a boundary line or other special
circumstance before determining the extent of their respective continental
shelf[25].
‘Article 6’ of the Continental Shelf Convention stated to be a
non-customary law is not compoundable as addressed in the case of “Nicaragua
v. United States[26]”, by
the ICJ itself it was asserted that in order to create customary international
law, states use “opinio juris” and “state practice” as the basic aspects for
evaluation. Additionally, it was stated that customary international law can
arise from state practices that are uniform and consistent and from the
perception that such practices are mandated by law (opinio juris). The practice
of equitable distance and division of maritime rights were adhered to as a
regular state practice since decades in all cases prior to the present decision
falling under the nature of an established norm and standard practicable by all
the nations. ‘Article 38(1)(b)’ of the Statute of the
International Court of Justice recognizes treaties and fundamental principles
of law as secondary sources of international law, in addition to customary
international law. The court citing Customary International Law, argued that
equidistance was not customary law during the period of the instant case. This
argument was supported by notable state practice that before the 1969 ruling.
Even though it hasn't been approved by every party, the 1958 Geneva Convention
on the Continental Shelf was supported by a number of rulings that codify
equitable principles and reflect customary international law.
In 1964, Denmark, United
Kingdom and Norway signed a tripartite agreement pertaining to the North Sea
Continental Shelf, with the delimitation based on equal distance. Furthermore,
the accords that were widely ratified following the North Sea cases demonstrate
the growing popularity of equidistance as customary law. According to the
decisions in the present case, the rights of impacted communities and
indigenous peoples have also not been adequately taken into account during the
delimitation process, particularly in relation to access to traditional fishing
grounds and cultural heritage sites. While they might not specifically
address the delimitation of maritime rights, international human rights accord
like the ‘Universal Declaration of Human Rights’ emphasize the protection of
the rights of all individuals and groups. The Court ought to have been more accommodating in its
decision-making process in the North Sea Continental Shelf case. The Court may
have reached a more equitable resolution to the conflict between Germany and
the Netherlands by considering changing circumstances and viewpoints on equity
relying on the maritime boundaries’ outcome of 2009 Black Sea “Ukraine v.
Romania[27]”
case. The ICJ in this case that defining maritime borders in the Black Sea
requires some wiggle room. As an example of its flexible approach to dispute
resolution, the Court took into account past usage, geographical arrangements,
and the equitable interests of both parties.
In conclusion, although the rulings
in the present Continental Shelf Case are recognized by many as authoritative
applications of international law, there is still room for criticism. The
decision of overlooking equitable principle thereby giving prominence to
equidistant principle under customary international law aligning with pertinent
circumstances are called into question by a by the researchers through the
stated counterarguments and alternative conclusions. The researchers are of the
opinion that the adjudicating bodies must go further by delineating maritime
boundaries in a more comprehensive and context-specific manner, accounting for
all pertinent variables and interests. In this way, maritime boundary conflicts
can be settled in a just and fair manner, advancing international law and
preserving peace and fidelity within the international community.
