Yes. When an accused service member’s mental health is genuinely in question before trial, a sanity board can be requested, and the defense is among those expressly permitted to ask for one. The mechanism is found in Rule for Courts-Martial (RCM) 706, which governs inquiries into the mental capacity and mental responsibility of an accused. A sanity board is not a tactic to delay proceedings; it is a formal evaluation designed to answer two specific legal questions about the accused’s mind, and military law builds in a path for the defense to invoke it.
What a sanity board decides
An RCM 706 inquiry examines two separate issues that are easy to confuse but legally distinct.
The first is competence to stand trial, sometimes called mental capacity. This asks about the accused’s present condition: does the accused have sufficient mental capacity to understand the nature of the proceedings against him and to conduct or cooperate intelligently in his own defense? A defendant who cannot grasp what is happening or assist his attorney cannot be tried, regardless of what he understood at the time of the alleged offense.
The second is mental responsibility, which looks backward to the time of the offense. This asks whether the accused, as a result of a severe mental disease or defect, was unable to appreciate the nature and quality or the wrongfulness of his conduct. Lack of mental responsibility is an affirmative defense in courts-martial, and the sanity board’s findings on this question can shape whether that defense is viable.
A single board can be asked to address both questions, and the inquiry is conducted by one or more qualified mental health professionals, typically a psychiatrist or clinical psychologist.
Who may request a board
RCM 706 deliberately spreads the authority to raise the issue across many participants. A request for a sanity board may come from the commander, the preliminary hearing officer, trial counsel, defense counsel, the military judge, or a member of the court. The defense is squarely on that list, which means defense counsel can and routinely does request a board when there is reason to believe the accused’s mental state is in play.
Where the request goes depends on the stage of the case. Before charges are referred to a court-martial, the request is directed to the convening authority. After referral, the military judge has the authority to order the inquiry. This division tracks who controls the case at each phase.
The standard for granting a request
A request for a sanity board is not granted automatically, but the threshold is not high. The governing principle is that an inquiry should be ordered when the request is made in good faith and is not frivolous, in other words, when there is some reasonable basis to question the accused’s mental capacity or mental responsibility. The defense does not need to prove that the accused is incompetent or lacked responsibility; it needs to show enough to raise a genuine question warranting professional evaluation.
That basis can come from many sources: documented psychiatric history, behavior observed by counsel or the command, bizarre conduct surrounding the alleged offense, a traumatic brain injury, prior hospitalization, or an inability to communicate coherently with the defense team. When such indicators exist, refusing to order an inquiry can be an abuse of discretion, and military appellate courts have set aside results where evidence emerging during proceedings should have prompted a further inquiry into the accused’s mental state.
What happens during and after the inquiry
Once ordered, the board evaluates the accused and answers the referred questions. The board typically renders findings such as whether the accused suffered from a severe mental disease or defect, whether that condition affected his ability to appreciate the wrongfulness of his conduct at the time of the offense, and whether he currently has the capacity to understand the proceedings and assist in his defense.
The handling of the board’s report involves careful confidentiality rules. The full report and the underlying examination generally are protected, and the broader contents are not freely disclosed to the prosecution. The defense receives the board’s conclusions, and trial counsel ordinarily receives only the ultimate findings rather than the accused’s statements to the board, in order to protect against using the compelled evaluation as a source of incriminating evidence. These protections exist because the accused is, in effect, being examined under legal compulsion, and the system guards against turning a mental health inquiry into a prosecution tool.
How the findings affect the case
A board’s conclusions can reshape a prosecution. If the board finds the accused presently incompetent to stand trial, proceedings are suspended until competence is restored, because trying an incompetent defendant is not permitted. If the board supports a conclusion that the accused lacked mental responsibility at the time of the offense, that bolsters the affirmative defense, though the defense still must be litigated and the ultimate determination rests with the factfinder, not the board. Even where the board does not establish a complete defense, its findings can inform plea negotiations, sentencing, and the broader strategy.
Practical guidance
A service member who believes mental health is a genuine issue should raise it with defense counsel as early as possible, ideally before referral, so the request can be timed appropriately and supported with records. Counsel will assess whether there is a good-faith, non-frivolous basis and, if so, request the board through the proper authority. Because the inquiry implicates competence, a potential affirmative defense, and sensitive confidentiality rules, it should be pursued deliberately and with qualified military defense representation rather than handled informally.
