The author examines historical facts, philosophical works, scientific publications of professors of near and far abroad on international law, analyzes international treaties in order to determine chronology of the evolution of international criminal justice and its bodies from idea to legal regulation within the framework of modern international criminal law. Thus, within the framework of academic paper, the works of Ch. Bassiouni, A. Volevodz, F. Martens, G. Moynier, A. Dorskaya etc. were studied and analyzed. Special attention was paid to the work of Hugo Grotius “On the Law of War and Peace” (“De jure belli ac pacis") and his understanding of justice, as well as Cicero's ideas about the “true law”. The author also studied the provisions of the Versailles Peace Treaty, documents of the League of Nations regarding the draft Convention on the creation of an international criminal court, a brief review of the constituent documents for the establishment of ad hoc tribunals and the International Criminal Court. Based on the analysis, author offers his own vision of the definitions of “international criminal justice” and “international criminal justice bodies”.
