The use of classified documents during an Article 32 preliminary hearing is governed by a strict set of rules and procedures designed to balance the accused’s right to a thorough investigation with the government’s compelling interest in protecting national security. These procedures are primarily outlined in the Military Rules of Evidence (specifically MRE 505) and related regulations.
If classified information is relevant to the charges, the hearing must be conducted in a secure, closed session. All participants, including the Preliminary Hearing Officer (PHO), counsel, the accused, and the court reporter, must have the appropriate security clearances and a “need to know.” The hearing room itself must be a secure facility approved for the handling of classified material.
The government must provide the defense with access to the relevant classified evidence, but this is done under controlled conditions. Defense counsel must obtain the necessary security clearances. The accused may also need clearance to view evidence related to their own case. The handling, storage, and discussion of the classified documents must comply with all applicable security regulations to prevent unauthorized disclosure.
The PHO, in consultation with a designated government security representative, will make rulings on how the classified information can be used. There are procedures for using summaries or redacted versions of documents to minimize the exposure of sensitive information. Any disputes over the discoverability or use of classified evidence are handled by the PHO, and these issues can become highly complex, often requiring rulings that balance the accused’s right to present a defense against the potential damage to national security.
