Article VI
The tribunals shall
(a) confine the trial strictly to an expeditious hearing of the issues raised by the charges;
(b) take strict measures to prevent any action which will cause unreasonable delay, and rule out irrelevant issues and statements of any kind whatsoever;
(c) deal summarily with any contumacy, imposing appropriate punishment, including the exclusion of any defendant or his counsel from some or all further proceedings, but without prejudice to the determination of the charges.
Article VII
The tribunals shall not be bound by technical rules of evidence. They shall adopt and apply to the greatest possible extent expeditious and non-technical procedure, and shall admit any evidence which they deem to have probative value. Without limiting the foregoing general rules, the following shall be deemed admissible if they appear to the tribunal to contain information of probative value relating to the charges: affidavits, depositions, interrogations, and other statements, diaries, letters, the records, findings, statements and judgments of the military tribunals and the reviewing and confirming authorities of any of the United Nations, and copies of any document or other secondary evidence of the contents of any document, if the original is not readily available or cannot be produced without delay. The tribunal shall afford the opposing party such opportunity to question the authenticity or probative value of such evidence as in the opinion of the tribunal the ends of justice require.
Article VIII
The tribunals may require that they be informed of the nature of any evidence before it is offered so that they may rule upon the relevance thereof.
