Principle IV states: “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”.
This principle could be paraphrased as follows: “It is not an acceptable excuse to say ‘I was just following my superior’s orders'”.
Previous to the time of the Nuremberg Trials, this excuse was known in common parlance as “Superior Orders”. After the prominent, high profile event of the Nuremberg Trials, that excuse is now referred to by many as “Nuremberg Defense”.
