Article 78 of the Uniform Code of Military Justice (UCMJ), codified at 10 U.S.C. section 878, punishes the accessory after the fact: a person who, knowing that an offense has been committed, receives, comforts, or assists the offender in order to hinder or prevent the offender’s apprehension, trial, or punishment. Sometimes a witness who is connected to an offense refuses to testify against the principal, and the question arises whether that refusal can be used to infer that the witness is an accessory after the fact under Article 78. The answer is no in any direct sense. A refusal to testify cannot, by itself, supply the proof Article 78 requires, and where the refusal rests on a recognized privilege, the law forbids drawing any unfavorable inference from it. This article explains why.
What Article 78 actually requires
To convict someone as an accessory after the fact, the government must prove four things beyond a reasonable doubt: that a specified offense under the UCMJ was committed by a principal; that the accused knew the principal had committed that offense; that the accused thereafter received, comforted, or assisted the principal; and that the accused did so for the purpose of hindering or preventing the principal’s apprehension, trial, or punishment. Each element is demanding. The knowledge element requires actual knowledge that a specific offense was committed, not mere suspicion or general awareness that something happened. The assistance element requires an affirmative act of help, and the purpose element requires that the help was given to shield the principal from justice.
Nothing in these elements is satisfied by silence. Article 78 targets conduct that aids an offender after the crime. A witness who simply declines to speak has not received, comforted, or assisted anyone in the sense the statute means. Refusing to testify is an omission, not the affirmative act of assistance the offense requires.
Refusing to testify is not the same as assisting the offender
It is worth separating two different things that the question runs together. Helping an offender evade justice can be an act, and some such acts are independently punishable. Concealing evidence, hiding the offender, or lying to investigators are affirmative acts that could support an Article 78 charge or other offenses. But the bare refusal to give testimony at a proceeding is categorically different. Declining to answer is not the same as taking a step to shield the principal from apprehension, trial, or punishment. Treating silence as the equivalent of active assistance would collapse a careful distinction the law maintains.
The law forbids adverse inferences from privileged refusals
The point is sharpest where the refusal rests on a privilege. A witness may decline to testify for several lawful reasons. The Fifth Amendment privilege against self-incrimination allows a witness to refuse to answer questions that might tend to incriminate the witness. The Military Rules of Evidence (MRE) recognize this and provide that the assertion of the privilege against self-incrimination cannot be considered as raising any inference unfavorable to either the accused or the government. The spousal privileges in the rules likewise permit a spouse to decline to testify or to refuse to disclose confidential marital communications in many circumstances. Other privileges, such as the privilege for communications to clergy or for certain confidential relationships, can also justify a refusal.
When a witness validly invokes such a privilege, the system protects the choice rather than penalizing it. Drawing an inference of guilt, or of accessory liability, from a privileged refusal would defeat the very purpose of the privilege. It would force the witness to choose between speaking and being treated as if the silence proved wrongdoing, which is exactly the pressure the privilege is meant to relieve. For that reason, a privileged refusal cannot be the basis for inferring that the witness assisted the principal under Article 78.
What the refusal can and cannot lead to
A refusal to testify is not without consequences, but the consequences are not an inference of accessory liability. A witness who refuses to testify without a lawful excuse, after being properly ordered to do so and afforded any required immunity, may face separate accountability for the refusal itself. The UCMJ contains a provision addressing wrongful refusal to testify, and a witness can also face contempt proceedings. Those mechanisms punish the refusal as its own matter. They do not transform the refusal into evidence that the witness is an accessory after the fact to someone else’s crime.
For the principal’s prosecution, a witness’s unavailability through refusal may affect what evidence the government can present, and it can trigger questions about immunity, prior recorded testimony, and the Confrontation Clause. But none of that authorizes a court to reason from “this person would not testify” to “this person must be an accessory.”
Bottom line
A witness’s refusal to testify cannot be used to infer accessory liability under Article 78. The accessory-after-the-fact offense requires proof of an affirmative act of receiving, comforting, or assisting an offender, undertaken with knowledge of a specific offense and for the purpose of shielding the offender from justice. Silence is not such an act. And where the refusal rests on a recognized privilege, including the privilege against self-incrimination, the Military Rules of Evidence expressly bar any unfavorable inference. A refusal may expose the witness to separate consequences for the refusal itself, but it is not a substitute for the elements Article 78 demands.

Military law also changes over time.
