INTERNATIONAL MILITARY TRIBUNALS AND THEIR IMPACT ON THE DEVELOPMENT OF INTERNATIONAL CRIMINAL LAW

Abstract

The article provides a comprehensive study of the formation and development of international military tribunals as key institutions in the international criminal justice system. It examines the activities of the Nuremberg, Tokyo, International Tribunal for the former Yugoslavia, and International Tribunal for Rwanda, which laid the legal, procedural, and conceptual foundations of modern international criminal law. Their contribution to the formation of fundamental principles—individual criminal responsibility, inevitabil- ity of punishment, absence of immunity for senior officials, and universal jurisdiction over war crimes, crimes against humanity, and genocide—is summarized. The purpose of the article is to analyze the formation and evolution of international military tribunals, to study their contribution to the formation of modern norms and principles of international criminal law, and to assess the impact of these tribunals’ decisions on the further development of the international system of re- sponsibility for war crimes, crimes against humanity, and genocide. The current stage of evolution of international criminal justice is analyzed, reflecting the signing of the Agreement between Ukraine and the Council of Europe on the establishment of a Special Tribunal for the crime of aggression against Ukraine. It is noted that this initiative is a logical continuation of the historical tradition of international military tribunals, which began in Nuremberg, and at the same time, an innovative model of regional justice that goes beyond the classical mechanisms of the UN. It concludes that the international war tribunals established after World War II laid the foundation for modern international criminal law. The Nuremberg and Tokyo tribunals were the first to establish the principles of individual criminal responsibility, the inevitability of punishment, and the inadmissibility of invoking state immunity or following orders. The tribunals for the former Yugoslavia and Rwanda significantly developed these principles, establishing practices regarding genocide, crimes against humanity, and command responsibility, which became the foundation for the creation of the International Criminal Court. Contemporary challenges, in particular the Russian Federation’s aggression against Ukraine, have revealed the need to improve the mechanisms of international justice. The signing of the Agreement on the Establishment of a Special Tribunal for the Crime of Aggression against Ukraine is a logical continuation of the evolution of international criminal law and demonstrates the international community’s ability to adapt legal instruments to new threats.
