Interestingly, Raeder wanted to use British plans for Norway as part of his defense at Nurenburg, where his role in the Weser Exercise was a major part of the case against him. The British prevented it.
But on the other hand, the British Lord Chief Justice allowed Weiszacker to introduce the evidence of the “Secret Protocol” to the Non-Aggression Pact in his defense, despite the Soviet Prosecutor going ape over it’s disclosure.
Nuremberg was a very odd sort of jurisprudence.
