One of the central purposes of the international law of the sea is to define various maritime zones, their extent and limits. One of these zones is the continental shelf. The continental shelf in modern international law has two aspects: The continental shelf within 200 nautical miles from the shore of coastal States and the continental shelf beyond that limit. The United Nations Convention on the Law of the Sea provides that information on the limits of the continental shelf beyond 200 nautical miles shall be submitted by the coastal State to a scientific and technical commission, namely the Commission on the Limits of the Continental Shelf. The Commission is responsible for making recommendations to coastal States on matters related to the establishment of the outer limits of their continental shelves beyond 200 nautical miles. If the limits of the shelf established by a coastal State are on the basis of the recommendations, they are final and binding. The establishment of the continental shelf beyond 200 nautical miles has two main features: The establishment of the boundary line between the continental shelf and the international seabed area and the establishment of the boundary between the continental shelf of adjacent or opposite coastal States. Many questions concerning the relationship between these procedures have been left unanswered as well as the relationship between the Commission and international courts and tribunals. This thesis analyses the role of coastal States, the Commission and international courts and tribunals in the establishment of the continental shelf beyond 200 nautical miles and the interplay between them. It explores how the various sources of international law have contributed to the establishment of the current legal framework. The thesis explores the differences between the delineation and delimitation of the continental shelf beyond 200 nautical miles. It demonstrates that the role of the Commission is to curtail extravagant claims to the continental shelf beyond 200 nautical miles and protect the territorial scope of the international seabed area. It also shows that the role of international courts and tribunals in this field is essentially the same as their role in other types of disputes. It explains that the establishment of the boundary line between the continental shelf and the international seabed area and the establishment of the boundary between the continental shelf of adjacent or opposite coastal States is a separate process. Furthermore, it clarifies that the three-stage boundary delimitation method is applicable beyond 200 nautical miles. It also displays that no special rule of customary international law has evolved that is solely applicable to delimitations regarding the continental shelf beyond 200 nautical miles. The thesis addresses the interaction of the various mechanisms within the United Nations Convention on the Law of the Sea concerning the continental shelf beyond 200 nautical miles. Its main conclusion is that despite the possibility for tension to arise the relationship between the institutions is clear and precise and they together form a coherent system where each separate institution plays its own part in a larger process.
