Aggression and the Use of Force

As we take up the question of the definition of aggression today, for those interested in reading more about the issue, there is a good article on the subject at EJIL: Talk! on the definition the purposes of the Rome Statute of the ICC, which was decided upon at the international conference at Kampala two years ago. As discussed in the blog post, the new definition and associated "understandings" raise many interesting issues involving treaty interpretation.

The Kampala definition itself is as follows:For the purpose of this Statute, “crime of aggression” means the planning, preparation, initiation or execution, by a person in a position effectively to exercise control over or to direct the political or military action of a State, of an act of aggression which, by its character, gravity and scale, constitutes a manifest violation of the Charter of the United Nations.

You may also want to look at the full text of UN General Assembly Resolutions 2626 (Declaration on Friendly Relations), and 3314 (Definition of Aggression), that we will discuss in class and are only excerpted in the text.
