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.

The event was attended by approximately 100 representatives of 75 States Parties and served to advance understanding and awareness of the legislative mandate on the upcoming review of the Kampala amendments by the ASP Special Session in July.

GIPA letter to the ILC on Draft Article 7: On the occasion of the 76th Session of the International Law Commission (ILC) beginning on 28 April 2025, the Global Initiative for the Prevention of Aggression (GIPA) provided brief comments to the ILC on draft article 7 of the draft articles on immunity of State officials from foreign criminal jurisdiction. GIPA explains in its letter why there is no functional immunity from foreign criminal jurisdiction. Leaving the crime of aggression out of the list of crimes to which functional immunities do not attach would result in inconsistency and a risk of double standards. This could potentially fragment international law. For the full comments, see here.

This text will serve as the basis of negotiations at the upcoming Review to be conducted by the ICC’s Assembly of States Parties.

The Global Institute for the Prevention of Aggression is delighted that the amendment text is essentially what GIPA had proposed to states in the fall of 2023.
