Dispute Settlement in the Law of the Sea: Survey for 2023

Abstract This is the latest in a series of annual surveys in this Journal reviewing dispute settlement in the law of the sea, both under Part XV of the UN Convention on the Law of the Sea and outside the framework of the Convention. The most significant developments during 2023 were the judgments on the merits of a Special Chamber of the International Tribunal for the Law of the Sea ( ITLOS ) in the Dispute concerning Delimitation of the Maritime Boundary between Mauritius and Maldives in the Indian Ocean ( Mauritius/Maldives ) case and of the International Court of Justice ( ICJ ) in the Question of the Delimitation of the Continental Shelf between Nicaragua and Colombia beyond 200 Nautical Miles from the Nicaraguan Coast ( Nicaragua v. Colombia ) case; the commencement of two new cases before the ITLOS and the ICJ concerning the seizure and detention of vessels and climate change obligations, respectively; and the findings and recommendations of a panel established by the South Pacific Regional Fisheries Management Organisation to consider the validity of one of its fisheries conservation and management measures.
