Article 78 of the Uniform Code of Military Justice, codified at 10 U.S.C. 878, punishes the accessory after the fact. The offense reaches any person subject to the UCMJ who, knowing that an offense punishable by the code has been committed, receives, comforts, or assists the offender in order to hinder or prevent the offender’s apprehension, trial, or punishment. The line that decides these cases is the line between doing something to help an offender escape consequences and simply declining to help the government. Courts treat the first as concealment that can support a conviction and the second as non-cooperation that cannot.
What Article 78 actually requires
To sustain a conviction under Article 78, the government must prove four things beyond a reasonable doubt. First, that another person committed an offense punishable under the UCMJ. Second, that the accused knew that person had committed the offense. Third, that after the offense, the accused received, comforted, or assisted the offender. Fourth, that the accused did so for the purpose of hindering or preventing apprehension, trial, or punishment. Each element matters, but the third and fourth carry the most weight when the dispute is whether a service member crossed the line into criminal conduct.
The verb the statute uses is “assists.” That word demands an affirmative act. A military court reading Article 78 asks whether the accused did something to shield the offender, not whether the accused failed to expose him. This distinction is built into the structure of the offense and explains why so many Article 78 disputes turn on conduct rather than attitude.
Concealment is an affirmative act
Concealment is conduct that conceals either the offender or the offense itself. Hiding a person from investigators, destroying or moving physical evidence, giving false information to throw an inquiry off track, or providing a hiding place, transportation, money, or supplies designed to let the offender avoid capture all qualify as assistance. The help an accessory gives is not limited to acts meant to effect the escape or physical concealment of the principal. It also includes acts performed to conceal that the principal committed the offense at all. The common thread is that the accused took a step, however small, intended to frustrate the legal process.
Concealment also carries an intent requirement that courts scrutinize closely. The assistance must be intentional and designed to help the offender avoid legal consequences. Conduct that incidentally …
