The Commission's recommendations were not carried through at the time. The proposed international tribunal for war crimes was not established, because of the refusal of the German government to cooperate. Instead, a few German individuals accused of war crimes were tried in 1921 at the Leipzig War Crimes Trials by the German authorities themselves. However, the recommendations did bear fruit in the longer term. Following the Second World War, two international Allied tribunals were established in Nuremberg and Tokyo to try German and Japanese leaders accused of war crimes. The demand for a permanent tribunal for crimes against humanity continued even after those tribunals had been dissolved, leading eventually to the establishment of the International Criminal Court in 2002.
