Article 97 of the Uniform Code of Military Justice (UCMJ) punishes the unlawful detention of another person. The offense recognizes that the military gives many members real power to restrain others, and it polices the boundary between a lawful exercise of that power and an abuse of it. The phrase that captures this boundary is whether the apprehension, arrest, or confinement was done without proper authority. Understanding how that standard is evaluated explains why having a title or position is not the same as having authority in a given situation.
What Article 97 prohibits
Article 97 (codified at 10 U.S.C. 897) applies to any person subject to the code who, except as provided by law, apprehends, arrests, or confines another person. The two core elements are that the accused apprehended, arrested, or confined a certain person, and that the accused did so unlawfully, meaning without proper authority. The terms have distinct meanings: apprehension is the placing of restraint on a person’s freedom; arrest is the imposition of moral restraint through orders directing a person to remain within specified limits; and confinement is physical restraint, such as holding a person under guard or in a cell. The government need only show that the restraint was against the will of the person restrained; physical force is not required.
Authority to act versus authority in the moment
The most important feature of the standard is that having general authority to detain does not by itself make a particular detention lawful. A service member may hold a position that includes the power to apprehend, arrest, or confine, yet still violate Article 97 if that power is used without valid legal grounds in the specific instance. The evaluation therefore is not simply whether the accused was the kind of person allowed to detain others. It is whether, on these facts, there was a proper legal basis for this detention of this person at this time.
Sources of proper authority
Proper authority comes from law and regulation. Apprehension is governed by rules that permit it on probable cause that an offense has been committed and that the person to be apprehended committed it. Pretrial restraint, including arrest and confinement, is governed by the Rules for Courts-Martial, which set who may order it and the standards that must be met, such as a reasonable belief that an offense was committed and that restraint is warranted. When a detention conforms to these rules, it falls within the “except as provided by law” language and is not an offense. When it departs from them, the detention can be without proper authority even though the actor had a relevant role.
The role of reasonable belief
The standard is not one of strict liability. If there is a possibility that the accused reasonably believed the detention was justified, the prosecution must prove that the accused lacked grounds for that belief. This means the fact-finder examines what the accused knew and believed at the time, and whether that belief in the legality of the detention was reasonable under the circumstances. An honest and reasonable belief that proper grounds existed cuts against a finding that the detention was without proper authority, while a detention undertaken with knowledge that there was no valid basis points the other way.
Factors the fact-finder weighs
Evaluating the standard is fact-intensive. Relevant considerations include whether there was probable cause or a reasonable basis to believe an offense occurred, whether the person ordering or carrying out the restraint had the authority to do so under the governing rules, whether required procedures were followed, the duration and conditions of the restraint, and whether the detention continued after any lawful basis ended. A detention that was proper when it began can become unlawful if it is prolonged beyond what the law allows, because the authority must support the restraint for as long as it lasts.
What the standard is not
The “without proper authority” standard does not turn on whether the detained person was ultimately guilty of anything. A detention can be lawful even if charges are later dropped, and unlawful even if the person turns out to have committed an offense, because the question is whether proper grounds and procedures existed at the time. Nor does it turn on the accused’s motive in isolation; the focus is on the legal basis for the restraint, although motive can be relevant evidence of whether the accused believed the detention was justified.
Practical takeaway
Under Article 97, the “without proper authority” standard is evaluated by asking whether there was a valid legal basis for the specific apprehension, arrest, or confinement, not merely whether the accused held a position that sometimes permits detention. The analysis looks to the governing rules on apprehension and pretrial restraint, to whether required procedures were followed, and to whether the accused had a reasonable belief in the legality of the detention, which the government must disprove if it is fairly raised. Because these cases depend heavily on the facts and on the applicable procedural rules, anyone accused under Article 97, or anyone who believes they were unlawfully detained, should consult qualified military defense counsel.

Military law also changes over time.
