The Treaty of London, August 8, 1945 (59 Stat. 7544), provided for the creation of the International Military Tribunal and the Charter of the Tribunal. The first session of the General Assembly of the United Nations unanimously affirmed the principles of international law recognized by the Charter and judgment of the Nurnberg Tribunal and directed the International Law Commission to formulate them into an International Criminal Code (Res. 95 [1], 11 December 1946). "The Nurnberg Principles" were adopted by the International Law Commission, June-July 1950:

Principle I. Any person who commits an act which constitutes a crime under international law is responsible therefor and liable to punishment.

Principle II. The fact that internal law does not impose, a penalty for an act which constitutes a crime under international law does not relieve the person who committed the act from responsibility under international law.

Principle III. The fact that a person who committed an act which constitutes a crime under international law acted as Head of State or responsible government official does not relieve him from responsibility under international law.

Principle IV. The fact that a person acted pursuant to order of his Government or of a superior does not relieve him from responsibility under international law, provided a moral choice was in fact possible to him.

Principle V. Any person charged with a crime under international law has the right to a fair trial on the facts and law.

Principle VI. The crimes hereinafter set out are punishable as crimes under international law:
