On 28 April 2023 the Special Chamber of the International Tribunal for the Law of the Sea (ITLOS) formed to deal with the Dispute concerning the delimitation of the maritime boundary between Mauritius and Maldives in the Indian Ocean (Mauritius/Maldives) delivered its Judgment of 28 April 2023. This follows the previously reported Judgment of 28 January 2021 in the incidental proceedings concerning the preliminary objections raised by the Maldives. The operative part of the Judgment of 28 April 2023 unanimously concluded:
(1) Decides that the single maritime boundary delimiting the exclusive economic zones and the continental shelves of the Parties within 200 nm extends from west to east between the intersections of the respective 200 nm limits determined in paragraphs 248 and 250 above and is composed of geodetic lines connecting the following points in WGS 84 as geodetic datum: Point 1 with coordinates 2° 17′ 21.4″ S and 70° 11′ 56.2″ E; turning points 2 to 36 with the coordinates identified in paragraph 249 above; Point X (Point 37) with coordinates 3° 07′ 28.9″ S and 73° 19′ 11.0″ E; and Point Y (Point 38) with coordinates 3° 20′ 54.8″ S and 75° 12′ 52.1″ E.Dispute concerning delimitation of the maritime boundary between Mauritius and Maldives in the Indian Ocean, Judgment of 28 April 2023, para. 466.
(2) Finds that its jurisdiction to delimit the continental shelf between the Parties includes the continental shelf beyond 200 nm.
(3) Rejects the objection raised by the Maldives to the admissibility of Mauritius’ claim to the continental shelf beyond 200 nm on the grounds that Mauritius’ submission to the CLCS was not filed in a timely manner.
(4) Finds that, in the circumstances of the present case, it is not in a position to determine the entitlement of Mauritius to the continental shelf beyond 200 nm in the Northern Chagos Archipelago Region and decides that, consequently, it will not proceed to delimit the continental shelf between Mauritius and the Maldives beyond 200 nm.
Declarations to the Judgment of 28 April 2023 were attached by Judge Paik, Judge Heidar and Judge ad hoc Schrijver.
