The status of “international law” is examined critically. In the first section, the basis of (national) legislation is described. This consists of an inquiry into a credible meaning of “natural law”. It is focused on the question whether universal principles exist and, if so, of what kind. Section 2 deals with the issue of enforcement. National legislation invariably realizes this, but this is not obvious at the international level. Section 3 deals with human rights. It is discussed whether their presence points to the existence of “international law”. To this end, a possible reason for these rights to have developed is expounded.
