On June 27, 2016, Palestine became the thirtieth state party to the Rome Statute of the International Criminal Court (ICC) to deposit its instrument of ratification of the amendments addressing the crime of aggression (Kampala amendments). Palestine’s acceptance is significant because a minimum of thirty ratifications are required before the amendments may be activated. Because participants in the 1998 Rome Conference could not agree on a precise definition of the crime of aggression, the drafters deferred the decision for a subsequent review conference, stating in Article 5.2, “The Court shall exercise jurisdiction over the crime of aggression once a provision is adopted . . . defining the crime and setting out the conditions under which the Court shall exercise jurisdiction with respect to this crime.”  At the Rome Statute’s 2010 Review Conference in Kampala, Uganda, the ICC Assembly of States Parties established a legal definition for the crime of aggression, which was adopted by consensus. According to the press release, the decision to activate must also be adopted by the ICC’s Assembly of States Parties on or after January 1, 2017, in order to allow the ICC to exercise jurisdiction over the crime of aggression. An activation vote is scheduled for December 2017.
