Since the very beginning of its existence the United Nations, like the League of Nations before it, has experienced how difficult it is to define the scope of the most general and fundamental principles of international law in a declaration of legal significance. Today this is still the case, as appears from the efforts undertaken since the establishment four years ago of a United Nations Special Committee, which was given the task of studying in what way and to what extent the primary principles of international law contained in the Charter could yield rules adapted to the changed world situation. Before considering in detail the most recent proceedings of the Special Committee, it seems useful briefly to recall the context within which the Committee started its work.
