When a court-martial or investigation is underway, the integrity of the process depends on witnesses who can come forward and testify without fear. The military justice system treats attempts to intimidate those witnesses as a serious offense in its own right, separate from whatever conduct prompted the original proceeding. A service member who pressures a witness to stay silent, to change a story, or to avoid an interview can face a fresh charge, additional pretrial restrictions, and consequences at sentencing. Understanding how the system responds requires looking at the governing offense, the orders commanders can impose, and the way courts treat such conduct as evidence.
Obstructing justice under Article 131b
The primary charging vehicle for witness intimidation is Article 131b of the UCMJ, obstructing justice, codified at 10 U.S.C. section 931b. The article punishes a person who, having reason to believe that criminal or disciplinary proceedings are pending, wrongfully does an act with intent to influence, impede, or obstruct the due administration of justice.
Witness intimidation fits squarely within this offense. The elements the prosecution must prove are that the accused did a certain act; that the accused did so in the case of a person against whom the accused had reason to believe there were or would be criminal or disciplinary proceedings pending; that the act was done with the intent to influence, impede, or obstruct the due administration of justice; and that, under the circumstances, the conduct was wrongful. Telling a witness not to talk to investigators, threatening adverse consequences for cooperating, or pressuring a victim to recant all satisfy these elements when done with the required intent.
Two features of the offense are worth emphasizing. First, the proceedings need not have formally begun. It is enough that the accused had reason to believe charges or disciplinary action were pending or coming. Conduct aimed at a witness during an early investigation, before any charge is preferred, can still be obstruction. Second, the government does not have to prove that justice was actually obstructed. The offense turns on the intent behind the act, not on whether the witness was in fact deterred or whether the testimony actually changed.
Related offenses
Depending on the facts, intimidation can also implicate other articles. If the pressure includes an explicit threat of violence, communicating a threat under Article 115 may apply. If the conduct involves wrongful physical contact or an offer of violence, an assault charge under Article 128 may fit. Where the intimidation is part of a scheme involving a bribe or improper inducement, additional theories may be available. Prosecutors sometimes charge in the alternative, though they must avoid an unreasonable multiplication of charges arising from a single course of conduct.
No-contact orders and pretrial restraint
Beyond the punitive articles, commanders have administrative and pretrial tools to prevent intimidation before it happens. A commander or military magistrate can issue a no-contact order directing the accused to refrain from contacting a named witness or victim, directly or through third parties. Violating a lawful no-contact order is itself punishable as a violation of Article 92, failure to obey a lawful order, and can also be treated as further obstruction.
When the risk of witness tampering is high, that risk bears directly on pretrial confinement decisions. The Rules for Courts-Martial allow pretrial confinement when it is necessary to ensure the accused’s presence or to prevent serious misconduct, and a demonstrated intent to interfere with witnesses is among the considerations that can justify confinement or other conditions on liberty. In this way, the threat of intimidation can change the accused’s pretrial status well before any new charge is tried.
Intimidation as evidence at trial
Witness intimidation also has evidentiary consequences. Evidence that an accused tried to silence or pressure a witness can be admitted as consciousness of guilt, on the theory that someone confident in innocence has no reason to suppress testimony. This makes intimidation doubly costly, because it can both generate a new charge and strengthen the government’s case on the underlying offense.
Conversely, the defense is entitled to scrutinize whether the alleged intimidation actually occurred and whether it carried the required wrongful intent. Not every contact with a witness is improper. A defense investigator may lawfully interview witnesses, and an accused may have legitimate, non-coercive reasons to communicate with family members who happen to be witnesses. The line is crossed when the purpose is to influence, impede, or obstruct, and when the conduct is wrongful under the circumstances.
Consequences and sentencing
A conviction under Article 131b carries significant maximum punishment, and obstruction directed at the very proceeding in which the accused is being tried tends to be viewed gravely by sentencing authorities. Even where intimidation is not separately charged, evidence of it can be considered in aggravation, reflecting a judgment that interference with the truth-seeking function strikes at the heart of the justice system. For an accused, the practical lesson is that attempting to manage witnesses almost always makes the situation worse, both legally and in the eyes of the court.
Bottom line
The military treats witness intimidation during pending UCMJ proceedings as a distinct and serious wrong. The principal charge is obstructing justice under Article 131b, which reaches intimidation even before formal charges are preferred and does not require proof that justice was actually obstructed. Commanders can impose no-contact orders, enforceable under Article 92, and intimidation can justify pretrial confinement and serve as evidence of guilt at trial. For anyone facing UCMJ action, the safest course is to route all witness communication through counsel and to avoid any contact that could be characterized as an effort to influence testimony.

Military law also changes over time.
