This article begins with brief observations on the dispute-settlement system contained in the 1982 UN Convention on the Law of the Sea (LOS Convention). It then reviews the rules of procedure of the Commission on the Limits of the Continental Shelf (the Commission) which are designed to prevent or minimize disputes concerning outer continental shelf boundaries. In this context reference is made to joint submissions by coastal States. The role of the institutions created by the LOS Convention—the International Seabed Authority, the International Tribunal for the Law of the Sea, in particular the Seabed Disputes Chamber, and the Commission—with respect to dispute settlement is examined. It also considers the circumstances when States Parties may or may not challenge the recommendations of the Commission.
