The way that actors create, implement, and control international law is far more complex today than it was thirty years ago. International law has become increasingly detailed and specific, as international relationships and transnational legal processes have become more complex. The distinction between national and international law is much less clear. States remain the primary actors, but there has been a multiplication and intensification of the role of sub-state and non-state actors. There is a continuous transformation of international law, by both public and private mechanisms, from the national to the international sphere and vice versa. The evolution of norms has also become increasingly dense. Any discussion in this arena must contend with new sources and new subjects of international law.
