The Allied Control Commission and the Communist Party of Finland raised the issue of the trials repeatedly during the spring and summer of 1945. When the Treaty of London (London Charter) August 8, 1945 defined three types of crimes, "war crimes", "crimes against peace" and "crimes against humanity", it became evident that Finland couldn't be the only country fighting on the German side where leaders wouldn't be convicted. On September 11, the parliament passed a law enabling prosecution of those responsible for war. The Supreme Court of Finland and leading judicial experts protested the law as conflicting with the constitution of Finland and contrary to Western judicial principles (it was designed to apply retroactively), but they didn't comment on the political necessity of it. The Finnish public regarded it as a mockery of the rule of law. Juho Kusti Paasikivi, who was the prime minister of Finland at the time, is known to have stated that the conditions of the armistice concerning this matter disregarded all laws.
