Article 97 of the Uniform Code of Military Justice (UCMJ) addresses a problem that is easy to overlook in a system built around authority and obedience: the abuse of the power to take another person into custody. Codified at 10 U.S.C. section 897, the article punishes the misuse of the very authority that the armed forces depend on to apprehend, arrest, or confine. It is one of the shorter punitive articles, but its application reaches into command decisions, military police work, and the everyday exercise of authority over subordinates.
This guide explains what Article 97 covers, what the government must prove to obtain a conviction, how the offense differs from civilian false imprisonment, the defenses that commonly arise, and what is at stake at sentencing.
The statutory text
Article 97 reads in full: “Any person subject to this chapter who, except as provided by law, apprehends, arrests, or confines any person shall be punished as a court-martial may direct.” The offense was retained as Article 97 through the 2019 reorganization of the UCMJ, so the article number and the substance remain current.
The statute is deceptively simple. The criminal conduct is apprehending, arresting, or confining a person. The qualifying phrase “except as provided by law” carries the weight, because nearly every act of taking custody in the military is, in fact, provided for by law. The offense lies in stepping outside that lawful authority.
What the three verbs mean
The article reaches three distinct acts, and they are not interchangeable.
Apprehension is the military term for taking a person into custody. It is the functional equivalent of a civilian arrest and is governed by Rule for Courts-Martial (R.C.M.) 302. Apprehension is accomplished by clearly notifying the person that they are being taken into custody.
Arrest, in the military sense, is a form of moral restraint imposed by order. Under R.C.M. 304, arrest directs a person to remain within specified limits. It is restraint by order rather than by physical confinement.
Confinement is physical restraint, governed by R.C.M. 305. It is the most severe form of pretrial restraint and ordinarily requires a probable cause determination and review by a neutral officer within set time limits.
Each verb describes a recognized mechanism of military restraint. Article 97 criminalizes the use of any of them without the legal authority to do so.
The elements the government must prove
To convict under Article 97, the prosecution must prove two elements beyond a reasonable doubt: first, that the accused apprehended, arrested, or confined a certain person; and second, that the accused unlawfully exercised authority to do so.
The first element is usually straightforward and often undisputed. The contested question is almost always the second element, whether the exercise of authority was unlawful. Restraint is unlawful when it is imposed without legal justification, for example by a person who lacks authority to impose it, against a person who is not subject to such restraint, or in a manner or for a purpose that the law does not permit.
Because the offense punishes the abuse of official power, Article 97 applies to those who hold the authority to apprehend, arrest, or confine and then misuse it. It is not the vehicle for purely private misconduct that happens to involve restraining someone.
How Article 97 differs from false imprisonment
Article 97 is frequently compared to civilian false imprisonment, and the comparison is useful but imperfect. Civilian false imprisonment is a general offense of unlawfully restraining another person’s freedom of movement, and it applies to private parties as readily as to officials.
Article 97 is narrower in one sense and broader in another. It is narrower because it targets the abuse of military authority to take custody rather than every conceivable restraint of liberty. A purely private restraint of another person, with no exercise of military custodial authority, fits more naturally under other provisions of the UCMJ. Article 97 is broader in the sense that it captures conduct by those holding official power that civilian law might treat as a regulatory or disciplinary matter rather than a crime. The defining feature is the wrongful exercise of the authority to detain.
Defenses that commonly arise
The most important defense is lawful authority. If the apprehension, arrest, or confinement was in fact authorized by law, regulation, or proper order, the conduct falls within the “except as provided by law” exception and is not an offense. A military police officer who apprehends a suspect on probable cause, or a commander who orders pretrial confinement following the required determinations, is acting lawfully.
A related defense focuses on the accused’s reasonable belief in the lawfulness of the restraint. Where the accused reasonably believed, based on the circumstances known at the time, that the restraint was authorized, that belief bears directly on whether the exercise of authority was wrongful. Honest and reasonable mistakes about authority can negate the wrongfulness the offense requires.
Mistake of fact can also be relevant. If the accused acted on a reasonable but mistaken understanding of facts that, had they been true, would have made the restraint lawful, that mistake may be a defense depending on how the offense is charged and proven.
Finally, the defense may contest whether the act amounted to apprehension, arrest, or confinement at all. Brief, consensual, or de minimis interactions may not rise to the level of restraint the statute contemplates.
Maximum punishment and sentencing
Historically the maximum punishment for unlawful detention under Article 97 has included a dishonorable discharge, total forfeiture of all pay and allowances, and confinement for three years. Service members and counsel should be aware that the sentencing framework for the UCMJ has changed in recent years. The 2019 reforms introduced sentencing parameters and criteria, and further changes took effect for offenses committed on or after December 27, 2023, which reorganized how maximum confinement is determined for many offenses. Because the applicable maximum can depend on the date of the offense and the current edition of the Manual for Courts-Martial, the precise ceiling in any given case should be confirmed against the controlling version of the Manual rather than assumed.
Whatever the technical maximum, an Article 97 conviction is serious. A punitive discharge alone carries lifelong consequences for employment, benefits, and reputation, independent of any confinement.
Practice considerations
For the defense, the center of gravity is lawful authority and the reasonableness of the accused’s belief in it. Building the record means reconstructing exactly what the accused knew, what authority the accused held, and what the governing rules and orders permitted at the moment the restraint was imposed. Documentation of the chain of command, applicable regulations, and the probable cause known at the time is often decisive.
For the government, the challenge is proving wrongfulness rather than the mere fact of restraint. Because so much military custody is lawful, the prosecution must show specifically why this exercise of authority fell outside the law, whether because the accused lacked authority, exceeded it, or used it for an improper purpose.
Bottom line
Article 97, UCMJ, is the military’s check on the abuse of custodial authority. It punishes apprehension, arrest, or confinement carried out without legal justification. The fact of restraint is rarely disputed; the real question is whether the accused exercised authority unlawfully. Because nearly all military custody is authorized by law, both prosecution and defense should focus on the specific source and scope of the authority involved and on whether the accused reasonably believed the restraint was lawful. Anyone facing an Article 97 allegation, or any commander or service member exercising custodial authority, should understand that the line between lawful restraint and a punitive offense turns on legal authorization and good faith, not on the fact that someone was held.

Military law also changes over time. The Military Justice Act of 2016 (effective January 1, 2019) and subsequent National Defense Authorization Acts renumbered and rewrote many punitive articles, revised the Article 32 preliminary hearing, and altered sentencing, clemency, and appellate procedures. Statutes, regulations, executive orders, the Manual for Courts-Martial, and decisions of the service Courts of Criminal Appeals and the Court of Appeals for the Armed Forces may have been amended, superseded, or reinterpreted after this article was written, and article numbers or procedures cited here may have changed.
