Article 31 of the Uniform Code of Military Justice gives service members a protection that civilians do not have in identical form, and a defense practice built around it treats that protection as more than a checkbox. Joseph L. Jordan is a former Army Judge Advocate who now practices military defense full time, and his published approach to court-martial work places early identification of self-incrimination violations near the center of case strategy. This article explains what Article 31 requires, how a violation actually changes the evidence at trial, and the sequence a defense built on that protection tends to follow. It does not promise any particular result, because outcomes depend on the specific facts of each case.
What Article 31 actually requires
Article 31, codified at 10 U.S.C. 831, bars compelled self-incrimination and requires a warning before a person subject to the Code questions someone suspected of an offense. The warning has three parts: the nature of the accusation, the right to remain silent about the offense, and notice that any statement may be used as evidence in a trial by court-martial. Unlike the civilian Miranda rule, which is generally triggered by custodial interrogation, the Article 31 warning can be triggered by official questioning even when the suspect is not in custody. That difference matters in a rank-driven environment, because a senior member asking pointed questions of a subordinate suspect can implicate the rule in settings that would not require a civilian warning.
The statute also addresses how a violation affects evidence. A statement obtained from a person in violation of the warning requirement, or through coercion, unlawful influence, or unlawful inducement, may not be received in evidence against that person at a court-martial. That exclusionary consequence is what gives the protection its practical force.
Why the violation is treated as a strategic lever, not just an objection
A confession or admission is often the strongest piece of the government’s case. If the statement was taken without a proper warning, or was the product of improper pressure, a successful challenge can remove that evidence before the members ever hear it. A defense oriented around Article 31, consistent with how Jordan describes his practice, treats the admissibility of any statement as a threshold question that can reshape everything downstream. Removing an admission can weaken the remaining proof, narrow the charges the government is willing to pursue, and change the negotiating posture of the case.
The leverage is not limited to the statement itself. Evidence that the government discovered only because of an unwarned or coerced statement can also be challenged as derivative, sometimes called fruit of the unlawful questioning. Identifying that chain early is part of why timing matters.
The sequence a violation-focused defense tends to follow
The first step is reconstructing exactly how each statement was obtained: who asked the questions, whether that person was acting in an official law-enforcement or disciplinary capacity, whether the member was already a suspect at that point, and whether a warning was given and understood. This often means reviewing investigator notes, any recordings, the timing of the warning relative to the first incriminating question, and the conditions of the interview.
The second step is filing a motion to suppress under the Military Rules of Evidence and the Rules for Courts-Martial. The military judge, not the members, decides admissibility. At a suppression hearing the defense can call and cross-examine the questioners, and the government generally bears the burden of showing that the statement was lawfully obtained. A defense practice that emphasizes Article 31 will develop these facts in detail rather than asserting a violation in conclusory terms.
The third step is using the ruling, whatever it is, to shape the rest of the case. A suppressed statement can support further motions, refine the theory of the defense, and inform decisions about whether to contest the charges at trial or pursue another resolution. Even a partial ruling that limits how a statement may be used can be valuable.
Common scenarios where the warning fails
Several recurring situations give rise to viable challenges. A supervisor confronts a service member about suspected misconduct without recognizing that the member has already become a suspect, so no warning is given. An investigator delivers a warning but only after the member has already begun making admissions. A member is told, expressly or by implication, that cooperation is expected or that silence will look bad, which can raise questions of unlawful influence given the authority gradient between ranks. Each of these turns on facts, and each is the kind of issue a defense focused on self-incrimination protections looks for at the outset.
What this approach does not do
Leveraging Article 31 is a legal strategy, not a guarantee. A military judge may find that a proper warning was given, that the questioner was not acting in a capacity that triggered the rule, or that the member was not yet a suspect. Some statements are admitted. The value of an early, detailed focus on the warning is that it tests the government’s strongest evidence at the point where exclusion has the greatest effect, and it preserves the issue for appeal if the trial ruling goes against the accused. A service member who believes a statement was taken improperly should raise it with qualified defense counsel quickly, while interview records and witness memories are fresh.
Conclusion
A defense approach centered on Article 31, as Joseph Jordan presents his practice, treats the lawfulness of every statement as a question that can move the whole case. The protection is broader than its civilian counterpart in when it applies, and its exclusionary remedy can remove a confession and any evidence derived from it. The work is fact-intensive: reconstruct how the statement was obtained, litigate admissibility before the judge, and use the result to shape the defense. The earlier counsel examines the questioning, the more strategically the protection can be used.

Military law also changes over time. The Military Justice Act of 2016 (effective January 1, 2019) and subsequent National Defense Authorization Acts renumbered and rewrote many punitive articles, revised the Article 32 preliminary hearing, and altered sentencing, clemency, and appellate procedures. Statutes, regulations, executive orders, the Manual for Courts-Martial, and decisions of the service Courts of Criminal Appeals and the Court of Appeals for the Armed Forces may have been amended, superseded, or reinterpreted after this article was written, and article numbers or procedures cited here may have changed.
