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.
