Detention authority in the military is real and routinely exercised. Commanders and those acting under their authority can apprehend, arrest, and confine service members under defined rules. Because that authority flows down a chain of command, a hard question arises when a subordinate carries out a detention that turns out to be unlawful: is the commanding officer who set it in motion liable under Article 97 of the Uniform Code of Military Justice, or does responsibility rest only with the subordinate who physically performed the act? The answer depends on the commander’s own conduct and state of mind, because Article 97 is not an automatic supervisory-liability statute. It punishes a person for unlawful exercise of detention authority, and a commander can fall within it through their own acts, including ordering a detention they knew or should have known was unlawful.
What Article 97 prohibits
Article 97, codified at 10 U.S.C. 897, provides that any person subject to the Code who, except as provided by law, apprehends, arrests, or confines any person shall be punished as a court-martial may direct. The elements are that the accused apprehended, arrested, or confined a certain person, and that the accused unlawfully exercised authority to do so. The article applies to persons who hold authority under the Code to restrain others; it is not aimed at private acts of false imprisonment by those without such authority. The prosecution must show the restraint was against the will of the person restrained, and that the accused lacked a reasonable belief that the restraint was lawful.
That last point is important. The offense is not strict liability. A commander or other authorized person who reasonably believed a detention was lawful has a defense, because the mental element requires the absence of a reasonable belief in lawfulness.
A commander is liable for the commander’s own acts
The cleanest path to commander liability under Article 97 is direct: the commander personally exercised detention authority unlawfully. If a commander orders that a service member be confined without legal basis, the commander is exercising the authority to confine, and doing so unlawfully can fall squarely within the article. The fact that a subordinate physically escorted the member to confinement does not move responsibility away from the commander who ordered it. In military law, one who orders or directs an act can be treated as a principal, responsible for the conduct they cause …
