Violations of the laws or customs of war under military law: comparative analysis of international and internal legislation of Ukraine

This paper addresses the question of the criminalization of war crimes, which are compared at the international and internal legislative level under military law. Considering current threats to the international legal order and security system, justice and defence sector actors, military lawyers and research fellows in military law are faced with the problems of the concept of responsibility for the most serious crimes in the world. The adoption of the Rome Statute of the International Criminal Court in 1998 raises the question of the internal legislation validity. The states Parties to International Criminal Court should revise the established conceptual approaches of responsibility for war crimes. The comparative analysis was made of the core and international military law.
