Non-judicial punishment, imposed under Article 15 of the Uniform Code of Military Justice (UCMJ), is the disciplinary track commanders use for minor offenses without resorting to a court-martial. Because it feels less formal than a trial, service members sometimes assume the rights that protect them in a criminal case do not reach it. When it comes to Article 31, that assumption is wrong in an important way. The warning requirement attaches to the questioning, not to the forum the case eventually lands in.
Article 31 attaches to interrogation, not to a particular proceeding
Article 31(b) provides that no person subject to the UCMJ may interrogate, or request any statement from, an accused or a person suspected of an offense without first informing them of the nature of the accusation, advising them of the right to remain silent, and advising them that any statement may be used as evidence against them in a trial by court-martial. The trigger is official questioning of a suspect, regardless of whether the matter is ultimately handled at court-martial, through administrative action, or by non-judicial punishment.
So when a commander or an investigator questions a service member who is suspected of an offense, and the questioning is for a law enforcement or disciplinary purpose by someone acting in an official capacity, the Article 31 advisement is required. The fact that the command is contemplating an Article 15 rather than a referral to court-martial does not switch off the obligation to warn before that interrogation occurs.
Why the warning is required before Article 15 questioning
The premise of Article 31 is the coercive pull a service member feels when a superior in rank or position asks questions. Congress enacted Article 31(b) in 1950 precisely to dispel that inherent compulsion to answer a superior. That coercive dynamic is fully present in the lead-up to non-judicial punishment, because the questioner is frequently the suspect’s own commander or someone in the chain of command. If anything, the pressure to talk can feel more direct when the person asking holds disciplinary authority over the member.
For that reason, an Article 31 advisory must precede questioning of any member suspected of a UCMJ offense when the questioning relates to that offense, and a contemplated Article 15 is squarely within that scope.
The rights a member retains inside the Article 15 process itself
The Article 15 procedure layers its own protections on top of the pre-questioning warning. A member offered non-judicial punishment generally has the right to remain silent, the right to consult with counsel about the decision, the right to present matters in defense, extenuation, and mitigation, and, in most circumstances, the right to refuse the Article 15 and demand trial by court-martial instead. These procedural rights are distinct from the Article 31(b) warning, but they reinforce the same principle: the member cannot be compelled to incriminate himself or herself to fuel the disciplinary action.
The right to remain silent during the proceeding means a member can decline to make a statement to the imposing commander. Choosing to present matters is the member’s option, not an obligation, and silence cannot be treated as an admission of guilt.
The consequence of skipping the warning depends on where the statement is used
Here is where the analysis gets practical. If a member is questioned without the required Article 31 advisement, the statutory exclusion in Article 31(d) makes that statement inadmissible against the member at a trial by court-martial. The exclusionary force of Article 31 is framed around court-martial proceedings.
Non-judicial punishment is not a court-martial. It is a commander’s disciplinary tool, and the rules of evidence that govern courts-martial do not bind an Article 15 proceeding in the same way. A commander deciding an Article 15 is not conducting a trial and is not strictly applying the Military Rules of Evidence. This means the formal courtroom suppression remedy does not operate inside the Article 15 itself the way it would at a court-martial.
That distinction matters for strategy. The Article 31 warning is still required before the questioning, but the most powerful enforcement mechanism, exclusion of the statement, shows its full effect if the case proceeds to court-martial. A member who turns down the Article 15 and demands trial preserves the ability to litigate suppression of any unwarned statement in that forum.
Why the warning still matters even if Article 15 is the likely outcome
A member facing a possible Article 15 should not treat the warning as a formality with no teeth. Several reasons make it significant. The matter can escalate; a case that begins as a contemplated non-judicial punishment can be referred to a court-martial if the facts turn out to be more serious, and any unwarned statement gathered along the way becomes a live suppression issue there. The same statement can surface in a later administrative separation board or affect future proceedings. And the right to remain silent, which the warning announces, gives the member the practical ability to consult counsel before deciding whether to speak at all.
The bottom line
Article 31 applies to the questioning that precedes non-judicial punishment. If a suspect is interrogated for a disciplinary purpose by someone acting officially, the advisement must be given first, because the warning requirement is tied to the act of official interrogation rather than to the forum that follows. What changes with the forum is the remedy. The statutory exclusion of an unwarned statement is built for the court-martial setting, while the Article 15 proceeding itself is governed by the commander’s discretion and the member’s separate Article 15 rights, including the right to remain silent and to demand trial by court-martial.
