U.S. President Harry S. Truman’s executive order on September 28, 1945, proclaiming that the resources on the continental shelf contiguous to the United States belonged to the United States. This was a radical departure from the existing approach, under which the two basic principles of the law of the sea had been a narrow strip of coastal waters under the exclusive sovereignty of the coastal state and an unregulated area beyond that known as the high seas. The speed at which Truman’s continental shelf concept was recognized through emulation or acquiescence led Sir Hersch Lauterpacht to declare in 1950 that it represented virtually “instant custom.”
