Our purpose: Promoting peace through criminal justice – preventing crimes of aggression
Through the United Nations Charter, States have expressed their commitment “to save succeeding generations from the scourge of war”. They have agreed to renounce the illegal threat or use of force, and to settle their disputes “by peaceful means in such a manner that international peace and security, and justice, are not endangered”. States have the legal duty to abide by this commitment and the UN Security Council has the primary responsibility to enforce it.The Nuremberg Trials made it clear that criminal justice also has an important role to play for the promotion of peace and the deterrence of acts of aggression – though it remained limited and theoretical for many decades thereafter. With the 2010 Kampala amendments to the Rome Statute of the International Criminal Court, States Parties created a new mechanism to enforce the most important rule of international law: the prohibition of the illegal use of force under the United Nations Charter. This website is dedicated to making accountability a reality.

Joint Civil Society Statement: In light of the upcoming review of the aggression amendments in July 2025, over 40 NGOs signed a joint statement calling on all states parties to take the steps required to amend the International Criminal Court’s jurisdiction over the crime of aggression.
