After World War II, once the magnitude of Nazi atrocities became better known, the "crimes against humanity" were denounced. Besides the war crimes and the crimes against peace, it was above al this chief accusation that was principally pursued at the Nuremburg Trials.
These crimes included murder, mass extermination, genocide, torture, arbitrary arrest, etc. Ever since the Convention was adopted on November 26, 1968, by the General Assembly of the United Nations, these crimes against humanity have been considered imprescriptible, that is, they can never be ordered. They are thus precisely because they must always be condemned in the name of a law inscribed on the heart of man and anterior to all positive legislation. On the contrary, positive legislation is subject to the sanction of the law inscribed in the heart of man.
