"I thought at the time and still think that the Nuremberg trials were unprincipled. Law was created ex post facto to suit the passion and clamor of the time. The concept of ex post facto law is not congenial to the Anglo-American viewpoint on law. Before criminal penalties can be imposed there must be fair warning that the conduct which one undertook was criminal."—William O. Douglas, LL.D. (Associate Justice, Supreme Court of the U.S., 1939-1975)
We used to have these trials listed under postwar crimes, but since most visitors don't expect them there, hence had a hard time finding it, we moved it up one notch. If you wonder why we put it there in the first place: because the Allied tribunals and all the trials that followed in their wake were a crass violation of international law and thus a crime by definition. Here are papers bringing that message home.
