The Special Session of the Assembly of States Parties on the review of the amendments on the crime of aggression is approaching (it is scheduled for 7-9 July 2025 in New York, despite the attempts to postpone it and move to the Hague for various reasons, incl. potential problems of delegates with the entry to the USA). The proposal of the amendment to the Kampala amendments on the crime of aggression was tabled by Costa Rica, Germany, Sierra Leone, Slovenia and Vanuatu. It aims to change the current rules concerning the exercise of the Court’s jurisdiction over the crime of aggression in the case of state referral or proprio motu, by harmonizing them with the rules which are applied to other core crimes (genocide, crime against humanity and war crimes). Therefore, if the amendment is adopted, the Court would be able to prosecute the crime of aggression if at least one state involved (as a state aggressor or as a state victim of aggression) were a party to the amendments on crime of aggression.
