PAVEL ŠTURMA CYIL 6 ȍ2015Ȏ It is a truism to say that the ILC has always had on its programme some important topics of the international criminal law. 1 However, its role in drafting efforts leading to the definition of aggression seems to be neglected. Although the Commission was trusted by the General Assembly to prepare a draft statute of the ICC, in 1989, and it elaborated the first version of a draft statute for an International Criminal Court in 1994, 2 it is a well-known fact that the final text of the Rome Statute of the ICC is a result of work of the Preparatory Committee and the Diplomatic Conference on the Establishment of an International Criminal Court, adopted in July 1998. In the same vein, the preparatory works on the definition of the crime of aggression were done by a working group established by the Preparatory Commission already in 2002 and reporting to the Assembly of States Parties of the ICC (ASP). 3 Nevertheless, the ILC was involved in several attempts to define the crime of aggression almost from the commencement of its work in 1949. The Commission was requested by the General Assembly to deal with the issues of a definition of aggression in the framework of at least three different topics, i.e. the formulation of the Nuremberg principles, the question of defining aggression, and the draft Code of offences (crimes) against the peace and security of mankind. 4 Before coming to the drafting history, it should be made clear that this contribution stems from a nominalist approach which enables one to maintain the continuity of definitions from “crime against the peace” to “crime of aggression”. In fact, these are considered as just different denominations for the same legal concept. The vocabulary of international law is able to develop, from the early attempts, such as “a supreme offence against international morality and the sanctity of treaties” in Article 227 of the Treaty of Versailles (1919), 5 through “crime against the peace” in Nuremberg Charter (1945), up to “crime of aggression”. In substance, however, all the terms refer to the same crime, which consists in waging aggressive war, in violation of jus ad bellum . This contribution will try to demonstrate that there is definite continuity between the early definitions of the crime against the peace and the Kampala definition of the 1 See The Work of the International Law Commission .
