The herein presented deliberations led to the conclusion that in international law the term “crime against peace” has been replaced by the term “crime of aggression”. Crime against peace had been defined in the Charta of the International War Tribunal of 1945. No international law act has expressis verbis foreseen that this crime does not fall under the statute of limitation after a few years. Provisions of the Rome Statute of the International Criminal Court of 1998 do not mention such a crime. The Rome Statute foresees instead no temporal limitation of penalty for crime of aggression.
