Obstruction of Justice Under the UCMJ

Obstruction charges rarely arrive alone. They tend to attach to a primary allegation as a second specification, built from what a service member did after learning an investigation had started: a deleted thread, a quiet word to a witness, a coordinated account. What makes the charge distinct is that it survives independently of the underlying case. Even where the first allegation collapses, the conduct meant to bury it can stand as its own conviction, and the digital record that documents it is often harder to contest than the original facts.

A point of currency matters at the outset. Older guidance, and many secondhand summaries still in circulation, describe obstruction as an offense charged under Article 134, the general article. That framing predates the 2019 reorganization of the punitive articles. Obstructing justice is now its own enumerated offense, Article 131b, with defined elements of its own.

From the General Article to a Standalone Offense

For decades, obstruction of justice had no dedicated statute. It was prosecuted as a listed offense under Article 134, the residual provision that reaches conduct prejudicial to good order and discipline or service-discrediting in nature. The Military Justice Act of 2016 changed that. Effective January 1, 2019, Congress pulled several justice-interference offenses out of the general article and gave each its own number in a new 131-series (Pub. L. 114-328).

The practical consequence is more than cosmetic. As an Article 134 offense, obstruction carried the general article’s terminal element, the requirement that the conduct be prejudicial to good order and discipline or of a nature to bring discredit upon the armed forces. The enumerated offense at Article 131b drops that framing in favor of its own discrete elements, set out in the Manual for Courts-Martial. A current charge sheet alleges a violation of Article 131b, not “obstruction of justice under Article 134,” and a defense reading of the specification starts from the statute’s own text.

Article 131b, codified at 10 U.S.C. 931b, reaches “[a]ny person subject to this chapter who engages in conduct in the case of a certain person against whom the accused had reason to believe there were or would be criminal or disciplinary proceedings pending, with intent to influence, impede, or otherwise obstruct the due administration of justice.”

The Elements, and Why Intent Carries the Charge

The Manual for Courts-Martial breaks the offense into three elements: that the accused wrongfully did a certain act; that the act was done in the case of a person against whom the accused had reason to believe criminal or disciplinary proceedings were pending or would be; and that the accused acted with the intent to influence, impede, or otherwise obstruct the due administration of justice.

Two features of that structure shape almost every obstruction case. The first is that actual obstruction is not required. The statute targets the endeavor, so the government need not prove that the investigation was in fact derailed; an attempt that failed, a deletion that forensic recovery undid, still completes the offense if the intent was present.

The second is that intent does the heavy lifting. Conduct that incidentally complicates an inquiry is not obstruction unless it was done to interfere. A phone wiped out of long-standing habit, evidence lost to ordinary carelessness, or a record discarded before anyone had reason to anticipate proceedings does not satisfy the specific-intent requirement. Because intent is rarely stated aloud, it is typically built from circumstance: the timing of a deletion relative to the moment the member learned of an allegation, the selectivity of what was removed, and the consistency of the explanation later offered. Wiping only the messages tied to a suspected offense, in the hours after an interview notice, reads very differently from a routine purge of everything on the device.

The phrase “due administration of justice” is read broadly. It is not confined to a convened court-martial. It extends to the investigative and quasi-judicial machinery that surrounds a case: criminal investigations by service investigative organizations, Article 32 preliminary hearings, and the preparation of charges. It does not require that formal proceedings already be open, only that the accused had reason to believe they were pending or would be.

What the Offense Captures, and What It Does Not

Obstruction under Article 131b is broad enough to cover several distinct fact patterns, but its boundaries are worth marking because conduct just outside them is frequently mistaken for the crime.

Witness interference is a core example. Pressuring, intimidating, or coaching a witness to alter, withhold, or fabricate testimony falls squarely within the statute. The military setting adds a dimension absent from civilian cases: a rank and command relationship can supply pressure without an explicit threat. A senior member who contacts a subordinate witness to “talk through” what happened may be exerting influence the statute reaches, and the medium need not be a face-to-face threat. Text messages, relayed word through third parties, and posts aimed at a witness can all qualify, while leaving a recoverable trail.

Destruction or concealment of evidence is the other familiar category. Deleting messages, photos, or videos, clearing history, or hiding physical items can each support the charge when done with the requisite intent. Here the practical reality has shifted under the technology: material a member believes is gone often persists in device storage, cloud backups, carrier and platform records, or on the phones of others who received the same communications. The gap between what the accused thought was erased and what investigators can in fact reconstruct is frequently where an obstruction case is won or lost.

Two boundaries deserve emphasis, because they separate the crime from the lawful exercise of a right. Lying to an investigator is not obstruction under Article 131b; a knowing false official statement is its own offense, Article 107 (10 U.S.C. 907). The two can be charged from a single interview, but they are distinct articles with distinct elements, and the older habit of labeling a false statement as “131b” conflates the obstruction provision with the false-statement provision. Separately, declining to consent to a search or to surrender a passcode is the exercise of a constitutional protection, not obstruction. The line shifts only if a lawful, compulsory order to unlock a device issues under valid search authorization; refusal there may implicate Article 92 (failure to obey a lawful order), a different offense from obstruction, and an area where the law on compelled decryption continues to develop.

The 131-Series It Now Sits Within

The 2019 reorganization did not create Article 131b in isolation. It assembled a cluster of justice-interference offenses, and understanding where obstruction falls in that group clarifies what it does and does not cover.

• Article 131 (10 U.S.C. 931): Perjury. False testimony under oath in a proceeding.
• Article 131a (10 U.S.C. 931a): Subornation of perjury. Inducing another to commit perjury.
• Article 131b (10 U.S.C. 931b): Obstructing justice. The offense described here.
• Article 131c (10 U.S.C. 931c): Misprision of a serious offense. Concealing a known serious offense and failing to report it, rather than interfering with a proceeding.
• Article 131d (10 U.S.C. 931d): Wrongful refusal to testify. Refusing to qualify as a witness or to answer after being directed to do so by the presiding authority.
• Article 131e (10 U.S.C. 931e): Prevention of authorized seizure of property. Destroying or disposing of property to defeat a seizure the member knows is underway.
• Article 131f (10 U.S.C. 931f): Noncompliance with procedural rules. Unnecessary delay or knowing failure to enforce required process.
• Article 131g (10 U.S.C. 931g): Wrongful interference with an adverse administrative proceeding. Interference aimed at administrative actions, such as separation boards and inspector-general or regulatory inquiries, rather than at the criminal-justice process.

The practical takeaway is that conduct aimed at an administrative proceeding rather than a criminal one belongs to Article 131g, not Article 131b, and concealment of a crime without active interference sits at Article 131c. Charging documents in this area are precise about which subsection applies, and a specification that names the wrong one is contestable.

Why It Is Stacked, and the Limits on Stacking

Obstruction is added to a charge sheet for reasons that have less to do with the obstruction itself than with the case as a whole. The forensic proof of a deletion or a witness contact is often firmer than the proof of the underlying allegation, giving the government a fallback conviction if the primary charge does not carry. The same evidence is also probative on the main case, because steps taken to hide or distort proof tend to be read as consciousness of guilt. And the additional specification enlarges sentencing exposure.

That stacking is not unlimited. Where obstruction is charged alongside the offense it sought to conceal, the defense can raise multiplicity, when one charged offense is necessarily included in another arising from the same act, and unreasonable multiplication of charges, when the charges together exaggerate the seriousness of the conduct, under R.C.M. 906(b)(12). These are distinct doctrines: multiplicity is a legal question about whether the same act has been charged twice, while unreasonable multiplication is an equitable check the military judge applies even where the offenses are technically separate.

Maximum Punishment

A conviction under Article 131b carries a maximum punishment of a dishonorable discharge, forfeiture of all pay and allowances, and confinement for five years. (Some older summaries list a bad-conduct discharge for this offense; the current Manual authorizes a dishonorable discharge as the maximum punitive separation.) The maximum is a ceiling, not a likely outcome; the actual sentence turns on the nature of the obstruction and its effect on the proceeding.

For offenses committed on or after December 27, 2023, a further structural change applies. In non-capital general and special courts-martial, the military judge imposes the sentence, even in member trials, working within the sentencing parameters of the 2024 Manual rather than leaving the punishment to the panel. The five-year statutory ceiling remains the outer limit, while the judge sentences within the parameter set for the offense category.

Recurring Defenses

Because the offense is intent-driven, the most common defense is that the requisite intent was absent. A deletion consistent with a member’s ordinary handling of a device, undertaken before any reason to anticipate proceedings, undercuts the inference the government draws from timing and selectivity. The narrower and better-timed the deletion, the harder that argument becomes.

A related defense disputes that any proceeding was pending or reasonably anticipated. If nothing was open and nothing was on the horizon, the conduct was not aimed at the administration of justice. Courts read that element broadly, however; a formally opened investigation is not required, only a reason to believe proceedings were pending or would be.

Advice of counsel can bear on the wrongfulness of an act in narrow circumstances, but it does not reach conduct that is independently criminal. No lawyer can authorize the destruction of evidence or the intimidation of a witness, and counsel’s advice to invoke the right to silence is itself the exercise of a protected right rather than obstruction.

Frequently Asked Questions

Does obstruction still get charged under Article 134?

Not for conduct on or after January 1, 2019. The Military Justice Act of 2016 created a standalone offense at Article 131b (10 U.S.C. 931b), and a current charge sheet alleges that article rather than obstruction “as a listed offense under Article 134.” Materials that still describe obstruction as an Article 134 offense reflect the pre-2019 framing.

Is lying to an investigator the same as obstruction?

No. A knowing false official statement is its own offense, Article 107 (10 U.S.C. 907), distinct from obstruction at Article 131b. A single interview can give rise to both, but they are separate articles with separate elements.

Can deleting messages before any investigation begins be obstruction?

It depends on knowledge and intent. Routine deletion, done before a member had reason to believe proceedings were pending or likely, generally lacks the specific intent the statute requires. Deletion after learning of an allegation, especially when it targets only material tied to the suspected offense, can supply that intent through timing and selectivity.
