Preparing for a military commission is not the same as preparing for a court-martial, and that is the single most important thing to understand. The Guantanamo Bay commissions are a separate forum, created to try certain non-citizens for law-of-war offenses, governed by their own statute and rules. An attorney prepares by mastering how that system departs from the court-martial process they may already know.
A different forum with its own rules
The commissions operate under the Military Commissions Act of 2009, which reformed the earlier system and moved its procedures closer to, but still distinct from, courts-martial and federal trials. Preparation therefore begins with the governing law itself: the statute, the Manual for Military Commissions, and the body of rulings that have shaped practice at Guantanamo. This is a specialized jurisdiction, and the rules cannot be assumed from court-martial experience.
The procedural differences that drive preparation
Several specific features distinguish commissions, and each shapes how counsel readies a case:
- Counsel selection. The 2009 Act gave the accused more latitude in selecting military defense counsel, bringing this aspect closer to court-martial practice.
- Access to witnesses and evidence. Where a general court-martial gives the defense an “equal opportunity” to obtain witnesses and evidence, the commission framework affords a “reasonable opportunity,” comparable to that of a defendant in a civilian federal (Article III) court. That difference affects how aggressively and early the defense must move to secure proof.
- Hearsay and evidence rules. The 2009 reforms amended the hearsay rules to more closely resemble those in civilian courts and courts-martial, but counsel must work within the commission’s own evidentiary regime rather than the Military Rules of Evidence as applied at a court-martial.
Because protections in this forum have historically been more limited than in courts-martial or federal court, preparation includes anticipating issues, such as the handling of classified material and statements, that are distinctive to these cases.
What preparation looks like in practice
Picture a non-citizen accused of a law-of-war offense: the case proceeds before a military commission, a forum with its own rules that differ from a court-martial, which the attorney must prepare around.
The central point is that the commission is a distinct legal system, not a relocated court-martial. Effective preparation means learning that system on its own terms, the counsel rules, the evidence-access standard, the hearsay framework, and the security overlay, rather than importing assumptions from any other forum.
