Article 31 of the Uniform Code of Military Justice, 10 U.S.C. 831, gives service members a protection against compelled self-incrimination that in some ways exceeds the civilian Fifth Amendment right. A frequent question is whether these rights can be given up, and the answer is yes: like most procedural protections, Article 31 rights are waivable. But a waiver is valid only if it meets specific conditions, and the law places the burden on the government to prove a valid waiver occurred. Understanding how a waiver is made, and how it can be challenged, is central to any case involving a statement by a service member.
What Article 31 protects
Article 31(a) prohibits compelling any person subject to the code to incriminate himself. Article 31(b) requires that before an accused or a person suspected of an offense is interrogated or asked for a statement, he be informed of the nature of the accusation, advised that he does not have to make any statement regarding the offense, and warned that any statement he does make may be used as evidence against him at a court-martial. Article 31(d) provides that a statement obtained in violation of the article is inadmissible. Layered on top of this, for custodial interrogation, is the right to counsel recognized for service members through the application of Miranda principles in United States v. Tempia, and the warning and waiver procedures are governed by Military Rule of Evidence 305.
These are the rights at issue. A service member may choose to exercise them by remaining silent and, in custodial interrogation, by requesting counsel. Or he may choose to waive them and speak.
Yes, the rights are waivable
There is no rule that a service member must remain silent. A member who has been properly advised may decide to answer questions, and a statement made after a valid waiver is generally admissible. The system contemplates this; rights-advisement forms used by service investigators typically include both the advisement and a waiver section precisely because waiver is an ordinary and lawful outcome. The protection exists so that any decision to speak is an informed one, not to forbid speaking.
How a valid waiver is made
A waiver of Article 31 rights, and of the associated right to counsel, must be voluntary, knowing, and intelligent. Each element carries content.
Voluntary means the choice was the suspect’s own, free of coercion, threats, or improper inducement. A statement extracted by pressure, by promises of leniency, or by other unlawful inducement is not a voluntary waiver, and the resulting statement is vulnerable to suppression.
Knowing means the suspect was actually told his rights. This is why the Article 31(b) advisement must precede questioning of a suspect, and why a complete advisement, covering the nature of the accusation, the right to remain silent, and the evidentiary use of any statement, matters. A waiver of rights the suspect was never told about is not a knowing waiver.
Intelligent means the suspect understood the rights and the consequences of giving them up. The suspect must be capable of comprehending what he is surrendering. Factors such as language barriers, youth, mental state, or intoxication can bear on whether a purported waiver was truly intelligent.
In practice, the waiver is usually documented in writing and, where available, captured on audio or video. The member is read or shown the advisement, indicates that he understands, and then indicates whether he is willing to make a statement. A signed waiver form and a recording of the advisement are the typical proof. But the form is evidence of a valid waiver, not conclusive proof; the underlying conditions must actually be met.
The special rule for invoking counsel
The right to counsel during custodial interrogation has its own protective rule that limits how waiver can occur after an invocation. Under MRE 305, once a suspect in custodial interrogation requests counsel, interrogation must stop. A later waiver of counsel obtained during custodial interrogation is generally invalid unless the prosecution shows that the suspect himself initiated the further communication, or that the suspect was not continuously in a custodial setting between the request and the later waiver. This means investigators cannot honor a request for counsel and then return to press the suspect into waiving; the suspect must be the one to reopen the conversation. The same protective logic guards an unambiguous invocation of the right to silence.
Who bears the burden, and how a waiver is challenged
The burden of establishing a valid waiver rests on the government. When the defense moves to suppress a statement under MRE 304, the military judge decides admissibility, and the prosecution must show that the warning was given as required and that any waiver was voluntary, knowing, and intelligent. The defense can attack each element: that the advisement was missing or incomplete, that the member did not understand it, that the waiver was the product of coercion or improper inducement, or that a request for counsel was disregarded. The strongest challenges are documented ones, drawing on the advisement form, the recording, and investigator records to show that a condition for a valid waiver was not met. A statement obtained without a valid waiver is subject to exclusion under Article 31(d) and MRE 304.
Practical guidance for service members
Because waiver carries real consequences, the prudent course for any member who is, or may become, a suspect is to decline to make a statement until consulting counsel. Asking for a lawyer is not evidence of guilt, and once counsel is requested in custodial interrogation, questioning must cease. A member who chooses to waive should understand that he can stop at any time and reassert his rights, and that anything already said may be used against him.
Bottom line
Article 31 rights are waivable, but only on terms the law strictly defines. A valid waiver must be voluntary, knowing, and intelligent, made after a complete Article 31(b) advisement and, for custodial interrogation, the counsel advisement required under Tempia and MRE 305. Once a suspect invokes counsel, a later waiver is generally invalid unless the suspect reinitiated contact. The government bears the burden of proving a valid waiver, and a statement taken without one can be suppressed under Article 31(d) and MRE 304. The safest path for a service member is to consult counsel before deciding whether to waive at all.
