Abstract

This paper is a response to the latest Bangladesh/Myanmar case decided by the ITLOS on 14 March 2012, which is the first case concerning delimitation of the continental shelf beyond 200 nm. The paper aims to discuss the status and role of natural prolongation in delimiting this area. Natural prolongation constitutes the legal basis for entitlement to the continental shelf beyond 200 nm. Also, natural prolongation should play a role as a relevant circumstance in delimiting the continental shelf beyond 200 nm. To address these two issues, the judgment of the Bangladesh/Myanmar case will also be reviewed. Both the interpretation of the meaning of natural prolongation and its exclusion in the delimitation process are not convincing. Hence, the Judgment's future influence on the continental shelf delimitation is limited.

The continental shelf of a coastal State comprises the seabed and subsoil of the submarine areas that extend beyond its territorial sea throughout the natural prolongation of its land territory to the outer edge of the continental margin, or to a distance of 200 nautical miles from the baselines from which the breadth of the territorial sea is measured where the outer edge of the continental margin does not extend up to that distance.

87. This is due to the fact that all the cases afterwards are concerned with maritime delimitation within 200 nm. The Black Sea case is such an example. The Black Sea is an enclosed sea surrounded by six countries and all points are within 200 nm off the coast of at least one of the riparian states. Since none of the parties could claim a continental shelf extending beyond 200 nm based on natural prolongation criterion, the 200 nm distance allows the coastal states to claim rights over a continental shelf as well as EEZ up to 200 nm.

109. In fact, in the most recent Nicaragua v. Colombia case decided by the ICJ on 19 November 2012, the Court refused to even consider whether the maritime boundary between Nicaragua and Colombia should be that between the outer limit of the continental margin of Nicaragua with the 200 nm limit of Colombia, because the Court observed that “Nicaragua has not established that it has a continental margin that extends far enough to overlap with Colombia's 200 nm entitlement to the continental shelf measured from Colombia's mainland coast”.

Colombia), Judgment of 19 November 2012, at 46, para. 129, online: ICJ 〈http://www.icj-cij.org/docket/index.php?p1=3&p2=3&k=e2&case=124&code=nicol&p3=4〉.

135. The final delimitation line by the Tribunal is substantially identical with the provisional line claimed by Bangladesh as a result of the application of the angle-bisector method. In this aspect, although the Tribunal rejected the proposal by Bangladesh, the Tribunal made the delimitation line substantially in favour of Bangladesh; see Bangladesh/Myanmar case, Separate Opinion of Judge Gao, at 19−20, paras. 48−52.
