"Part II of this article sets a background for the possibilities of regional international criminal law enforcement by exploring regionalization of other substantive areas of international law enforcement. Part III argues that regionalization of international criminal law could be a normatively positive development as it might better balance the benefits and drawbacks of national and supranational enforcement. Part IV applies political science and international relations methods, particularly from a neo-functionalist perspective, to develop a theory of regionalization of international criminal law, arguing that states are highly likely to support regionalization. Part V explores various pathways to regionalization including the creation of regional criminal courts as well as a variety of softer forms of regionalism. Part VI considers two possible impacts of regionalization on substantive international law and suggests the likely development of procedural differentiation within a universal system."
