In this Article I argue that some norms are part of international law even if they have never been created by treaty or custom. Because such norms have never been posited, they are natural law norms, and my thesis is that these natural law norms are as much part of international law as the posited norms. By this I mean that these norms should figure in any catalog of what international law prescribes or permits.
