Legal Order in the World’s Oceans: UN Convention on the Law of the Sea assesses the impact of the 1982 Convention on the Law of the Sea (UNCLOS) and many aspects and challenges of modern law of the sea. The theme was selected in part to celebrate that this conference was the Center for Oceans Law and Policy’s 40th Annual Conference and in part to emphasize the seminal contribution to the Rule of Law from UNCLOS in building legal order in the world’s oceans. The comprehensive scope of this inquiry is presented in six parts. The topics are: Ocean Affairs and the Law of the Sea at the United Nations; the Area and the International Seabed Authority; the International Tribunal for the Law of the Sea and Dispute Settlement; the Commission on the Limits of the Continental Shelf; Sustainable Fisheries, including the UN Fish Stocks Agreement; and Operational Implementation—Maritime Compliance and Enforcement.
