ABSTRACT
“General principles of law,” which are one of the international legal system’s sources of law, are specifically derived from national legal systems. However, national legal systems internalize international legal norms and regenerate them in domesticated forms and applications. As a result, the two systems have and continue to cross-fertilize each other. The contemporary premise of the international legal system is predicated on the assumption that it regulates an international community of states and other legal subjects whose characteristics are similar to that of states. The international criminal justice system has come to represent a web of international and national institutions, which includes the International Criminal Tribunal for the Former Yugoslavia, International Criminal Tribunal for Rwanda, investigating bodies, national criminal justice systems, and the International Criminal Court. Therefore, from a systemic perspective, international criminal justice links, through the concept of complementarity, aspects of the international legal system and national legal systems.
