It can actually be seen pretty easily from the charter:
Article 19.
The Tribunal shall not be bound by technical rules of evidence. It shall adopt and apply to the greatest possible extent expeditious and nontechnical procedure, and shall admit any evidence which it deems to be of probative value.
Article 20.
The Tribunal may require to be informed of the nature of any evidence before it is entered so that it may rule upon the relevance thereof.
Article 21.
The Tribunal shall not require proof of facts of common knowledge but shall take judicial notice thereof. It shall also take judicial notice of official governmental documents and reports of the United Nations, including the acts and documents of the committees set up in the various allied countries for the investigation of war crimes, and of records and findings of military or other Tribunals of any of the United Nations.

Not bound to rules of evidence, and rumors as well as arbitrary government reports (by hostiles towards the accused) are allowed. That way you can frame almost everybody. However of the statements made during the trial may be of historiographic value, but that's about it. Claims and findings can't be taken on face value.
