Questions: As the rules on the drawing of baselines from which the breadth of the territorial sea is measured are not radically different in the 1982 UN Convention on the Law of the Sea from those in the 1958 Convention on the Territorial Sea and the Contiguous Zone, the Third UN Conference on the Law of the Sea is sometimes described as an opportunity missed to clarify the rules. Is this a fair assessment? How far do the 1982 rules promote certainty as to the spatial extent of coastal States` rights and jurisdiction over the ocean areas adjacent to their shores?
