Article 31 of the Uniform Code of Military Justice gives service members a right against compelled self-incrimination that is in some respects broader than the civilian Miranda protection. Article 31(b) requires that before questioning a person suspected of an offense, the questioner inform the suspect of the nature of the accusation, advise that the person does not have to make a statement, and warn that any statement may be used against them. When a service member invokes the right to remain silent or asks for a lawyer, that invocation is supposed to stop the questioning. The important issue is what legally follows if questioning continues anyway.
Invocation must be clear, and then questioning must stop
To trigger the protections, the invocation generally must be clear and unambiguous. A suspect who plainly says they want to remain silent, or that they want a lawyer, has invoked. Once that happens, the Military Rules of Evidence, particularly Mil. R. Evid. 305, require that interrogation cease. If the suspect requested counsel, questioning may not resume on the basis of the investigator simply re-reading rights and getting a response. The protection mirrors the Supreme Court’s rule in Edwards v. Arizona, which held that after a suspect invokes the right to counsel, interrogation must stop and may not resume unless counsel is made available or the suspect personally reinitiates the conversation.
The primary consequence is suppression of the statement
If questioning continues after a proper invocation and the suspect then makes a statement, the central legal consequence is that the statement is subject to suppression. Article 31(d) operates as an exclusionary rule: a statement obtained in violation of the warning and rights requirements is generally inadmissible against the accused at a court-martial. In practice, defense counsel files a motion to suppress, and the military judge decides whether the invocation was clear, whether questioning improperly continued, and whether any later statement was the product of that violation. If the judge agrees, the prosecution cannot use the tainted statement in its case.
Reinitiation and waiver after invocation
Continued questioning is not automatically a violation in every situation, which is why the facts matter. If the suspect, after invoking, personally reinitiates communication with investigators, a later statement may be admissible if the government can show a knowing, intelligent, and voluntary waiver under the totality of the circumstances. The burden is on the government, and merely responding to renewed questioning …
