A. The Outer Limits of the Continental Shelf The 1982 United Nations
Convention on the Law of the Sea (herein- ter the "Convention") marks
the beginning of a new era in the law of 1 the sea. The negotiations for
this treaty at the Third United Nations Conference for the Law of the
Sea (hereinafter "UNCLOS III"), lasted for nine years, from 1973 to
1982. The Convention regulates the principal aspects of international
oceans affairs. It establishes and fixes the limits of maritime zones,
provides for the rights and duties of states in these zones, establishes
the law app- cable in the international seabed area on the basis of the
principle of common heritage of mankind, imposes obligations on states
to protect the marine environment, and provides for the means of dispute
sett- ment. One of the most contentious and divisive issues at UNCLOS
III were the outer limits of the continental shelf. Previously, in the
1958 Con- 2 vention on the Continental Shelf (hereinafter the "1958
Convention"), no limits were established for the continental shelf.
States were allowed to claim areas of continental shelves based on their
capacity to exploit the mineral resources of the shelf. The legal
framework in the 1958 Convention would obviously conflict with the
principle of the common heritage of mankind. Delegates realized that
limits have to be est- lished, but up to where and on the basis of which
principles, was a c- tentious question.
