More recently, this enforcement has migrated to the domestic level (compare, e.g., the Special Panels in East Timor or the Special Court for Sierra Leone). All of this has led to the emergence of a system of international criminal law enforcement operating at a variety of levels. Burke-White asserts that a core level of this system -the regional level- remains unexplored and underdeveloped. Hence, in this paper he seeks to fill this void by providing a preliminary consideration of fundamental questions as to whether such regionalization would be useful and achievable.
