UN General Assembly Resolution n. 260 9 December 1948, the Convention on the Prevention and Punishment of the Crime of Genocide, was the first step towards the establishment of an international permanent criminal tribunal with jurisdiction on crimes yet to be defined in international treaties. In the resolution there was a hope for an effort from the Legal UN commission in that direction. The General Assembly, after the considerations expressed from the commission, established a committee to draft a statute and study the related legal issues. In 1951 a first draft was presented; a second draft followed in 1955 but there were a number of delays, officially due to the difficulties in the definition of the crime of aggression, that were only solved with diplomatic assemblies in the years following the statute's coming into force. The geopolitical tensions of the Cold War also contributed to the delays.
