When a service member faces serious charges and a mental health issue is in play, the defense must decide how early to surface it. The Article 32 preliminary hearing, governed by Rule for Courts-Martial (RCM) 405, is the first formal adversarial proceeding in a general court-martial track, so it is natural to ask whether a mental health defense can be previewed there. The short answer is that aspects of a mental health issue can be raised at the hearing, but the hearing is not the place where such a defense is decided, and counsel must weigh the limited benefits against the real risk of tipping a hand too early.
What the Article 32 hearing is for
The preliminary hearing has a narrow purpose. The preliminary hearing officer, or PHO, determines whether there is probable cause to believe the charged offenses occurred and that the accused committed them, considers jurisdiction and the form of the charges, and recommends a disposition. The PHO is not a trial factfinder and does not decide guilt or resolve affirmative defenses. That structural limit shapes what a mental health defense can accomplish at this stage. A defense of lack of mental responsibility is an affirmative defense decided at trial, not at the preliminary hearing.
How a mental health issue can surface at the hearing
Even though the PHO does not adjudicate the defense, there are legitimate ways a mental health issue can appear in the proceeding.
The defense may present evidence at the hearing in reasonable forms, and the rules allow the PHO to consider documentary material. If there is a written medical report bearing on the accused’s mental capacity or mental responsibility, that material can be offered and, when received, attached to the PHO’s report. This places the issue on the record and before the convening authority who will decide how to dispose of the charges.
A request for an inquiry into the accused’s mental condition can also originate around this stage. Under RCM 706, a sanity board can be requested to evaluate competence to stand trial and mental responsibility for the charged offenses, and a range of participants, including a PHO, trial counsel, defense counsel, the military judge, a commander, or a member, may request one. A good-faith, non-frivolous request is the standard, and the inquiry is the proper mechanism for developing the clinical questions that underlie a mental responsibility defense. Raising the need …
