On December 14, 2017, the Assembly of States Parties (ASP) to the Rome Statute of the International Criminal Court (ICC) adopted a resolution that activates the Court’s jurisdiction over the crime of aggression as of July 17, 2018. The ASP also released a report on facilitating the activation of ICC jurisdiction over the crime of aggression that discussed the history of the crime of aggression at the ICC, states parties’ positions on the matter, and procedural aspects of an activation decision. The resolution notes that jurisdiction for the crime of aggression will “enter into force for those States Parties which have accepted the amendments one year after the deposit of their instruments of ratification or acceptance and that in the case of a State referral or propio motu investigation the Court shall not exercise its jurisdiction regarding a crime of aggression when committed by a national or on the territory of a State Party that has not ratified or accepted these amendments.” The resolution was passed on the last day of the sixteenth session of the ASP, which was held from December 4–14, 2017, in New York.
