Military Justice Hub
The Uniform Code of Military Justice (UCMJ), enacted in 1950, is the foundation of military law in the United States. It applies to all branches of the armed forces and is enforced through a separate court system with its own rules of procedure and evidence.
Key UCMJ Articles
The UCMJ contains punitive articles (77–134) that define military offenses, as well as procedural articles governing courts-martial, non-judicial punishment, and appellate review.
Article 2 — Persons Subject to the UCMJ
General Provisions
Defines who is subject to military jurisdiction under the UCMJ, including active duty members of all branches, cadets, midshipmen, reservists on active duty or inactive duty training, retired members entitled to pay, and prisoners of war.
Article 10 — Restraint of Persons Charged
General Provisions
Requires that any person subject to the UCMJ who is charged with an offense shall be ordered into arrest or confinement as circumstances require. Charges must be tried by court-martial or dismissed with reasonable speed.
Article 15 — Non-Judicial Punishment
General Provisions
Authorizes commanders to impose non-judicial punishment (NJP) for minor offenses without a court-martial. Punishments may include extra duties, restriction, reduction in grade, and forfeiture of pay. Service members may refuse NJP and demand trial by court-martial (except on vessels).
Article 31 — Self-Incrimination and Rights Warnings
General Provisions
Military equivalent of Miranda rights. Requires that persons suspected of an offense be informed of the nature of the accusation, advised of their right to remain silent, and warned that any statement may be used as evidence. Predates the Miranda decision by 15 years.
Article 32 — Preliminary Hearing
General Provisions
Requires a preliminary hearing before charges may be referred to a general court-martial. A preliminary hearing officer evaluates whether probable cause exists, whether the charges are in proper form, and makes a disposition recommendation.
Article 77 — Principals
Punitive Articles
Any person punishable under the UCMJ who commits an offense, aids, abets, counsels, commands, or procures its commission, or causes an act to be done which would be an offense if directly performed, is a principal.
Article 80 — Attempts
Punitive Articles
Makes it an offense to attempt to commit any offense punishable under the UCMJ. The act must go beyond mere preparation and constitute a direct movement toward commission of the offense.
Article 86 — Absence Without Leave (AWOL)
Punitive Articles
Prohibits failing to go to an appointed place of duty, leaving an appointed place of duty, or being absent from one's unit without authority. Covers AWOL from a few hours to extended periods. Penalties increase with duration of absence.

Article 99 — Misbehavior Before the Enemy
Punitive Articles
Prohibits running away, shamefully abandoning a command, cowardly conduct, willfully failing to engage the enemy, and other acts of misbehavior in the presence of the enemy. Maximum punishment includes death.

Article 119 — Manslaughter
Punitive Articles
Covers voluntary manslaughter (unlawful killing in the heat of sudden passion caused by adequate provocation) and involuntary manslaughter (unintentional killing through culpable negligence or during commission of an unlawful act).

The 'general article' that covers three categories: disorders and neglects prejudicial to good order and discipline, conduct bringing discredit upon the armed forces, and crimes and offenses not capital. Includes specific listed offenses such as drunk driving, adultery, and fraternization.
Article 137 — Explanation of UCMJ Provisions
Miscellaneous Provisions
Requires that Articles 2, 3, 7–15, 25, 27, 31, 37, 38, and the provisions of Article 137 be carefully explained to every enlisted member at the time of entry or within fourteen days, and again after six months of service and upon reenlistment.
Key CAAF Decisions
The United States Court of Appeals for the Armed Forces (CAAF) is the highest military appellate court, reviewing decisions from the service branch Courts of Criminal Appeals.
United States v. Briggs
592 U.S. 154 (2020)
The Supreme Court reversed the CAAF, holding that the UCMJ's statute of limitations for rape offenses committed before 2006 was five years from the date of the offense, not unlimited. Resolved a circuit split on military sexual assault prosecutions.
Significance
Clarified that Congress intended a five-year limitations period for pre-2006 military rape cases, impacting pending and future prosecutions of historical sexual assault cases.
United States v. Hills
75 M.J. 350 (C.A.A.F. 2016)
CAAF held that multiplying charges under both Article 120 (sexual assault) and Article 134 (general article) for the same conduct violated the constitutional prohibition against unreasonable multiplication of charges.
Significance
Established important limits on prosecutorial charging discretion in military sexual assault cases, preventing stacking of charges for the same underlying conduct.
United States v. Denedo
556 U.S. 904 (2009)
The Supreme Court held that military appellate courts have jurisdiction to entertain coram nobis petitions to vacate court-martial convictions, even after a service member has completed their sentence and been discharged.
Significance
Expanded access to post-conviction relief in the military justice system, allowing former service members to challenge wrongful convictions through extraordinary writs.
United States v. Mangahas
77 M.J. 220 (C.A.A.F. 2018)
CAAF addressed the military judge's responsibilities when an accused's guilty plea may be improvident, holding that the judge must conduct a thorough providence inquiry to ensure the plea is knowing and voluntary.
Significance
Reinforced the heightened protections for guilty pleas in the military justice system, requiring detailed inquiry into the factual basis for each charge.
United States v. Fosler
70 M.J. 225 (C.A.A.F. 2011)
CAAF held that Article 134 charges must specifically allege either the terminal element of prejudice to good order and discipline or service-discrediting conduct, finding that the general article requires notice of the specific theory of liability.
Significance
Required greater specificity in Article 134 charging, ensuring service members have adequate notice of the theory under which they are being prosecuted under the general article.
United States v. Wilkerson
73 M.J. 1 (C.A.A.F. 2014)
CAAF upheld a convening authority's clemency power to disapprove findings and sentence, but the case prompted Congress to restrict convening authority clemency power in the FY2014 NDAA for sexual assault convictions.
Significance
Catalyst for major military justice reform, leading Congress to strip convening authorities of the power to overturn sexual assault convictions, fundamentally changing the military justice landscape.
United States v. Ortiz
76 M.J. 189 (C.A.A.F. 2017)
CAAF applied the Supreme Court's Carpenter decision to military law, holding that accessing a service member's cell phone location data without a warrant violated the Fourth Amendment, even in the military context.
Significance
Extended digital privacy protections to service members, establishing that cell phone location data requires a warrant even in the military justice system.
United States v. Murphy
74 M.J. 382 (C.A.A.F. 2015)
CAAF examined the admissibility of uncharged misconduct in sentencing proceedings, holding that Military Rule of Evidence 403 balancing applies to determine whether uncharged acts are admissible during the sentencing phase.
Significance
Provided important protections for accused service members during sentencing by requiring judges to balance the probative value of uncharged misconduct against its prejudicial effect.
United States v. Hennis
79 M.J. 370 (C.A.A.F. 2020)
CAAF upheld the military prosecution of a retired Army master sergeant for triple murder, finding that the dual sovereignty doctrine permitted military prosecution after a state acquittal because the military and state are separate sovereigns.
Significance
Confirmed that the dual sovereignty exception to double jeopardy applies between state and military courts, allowing the military to prosecute retired members for serious crimes even after state proceedings.
United States v. Bergdahl
80 M.J. 230 (C.A.A.F. 2020)
CAAF addressed issues of unlawful command influence arising from public comments by senior officials about the Bergdahl desertion case, examining the impact of political statements on the military justice process.
Significance
Highlighted the tension between political speech and the integrity of the military justice process, addressing concerns about unlawful command influence at the highest levels of government.
United States v. Marcum
60 M.J. 198 (C.A.A.F. 2004)
CAAF applied the Supreme Court's Lawrence v. Texas decision to military law, holding that consensual sodomy between adults could not be prosecuted under Article 125 without additional factors connected to military service.
Significance
Extended Lawrence v. Texas privacy protections to the military, requiring the government to show a service-connected reason for prosecuting private consensual conduct between adults.
United States v. King
78 M.J. 218 (C.A.A.F. 2019)
CAAF addressed the requirement for independent evidence corroborating a confession in military cases, holding that Military Rule of Evidence 304 requires evidence independent of the confession to establish the corpus delicti.
Significance
Reinforced the corroboration requirement for confessions in military courts, providing protections against false confessions and ensuring reliability of confession-based convictions.
United States v. Robinson
77 M.J. 294 (C.A.A.F. 2018)
CAAF addressed the issue of panel member selection and improper exclusion based on rank, holding that systematic exclusion of junior enlisted members from court-martial panels could constitute error.
Significance
Addressed fairness in the court-martial panel selection process, ensuring that panels reflect a fair cross-section of the military community as required by the UCMJ.
United States v. Yammine
81 M.J. 373 (C.A.A.F. 2021)
CAAF addressed the application of the Military Justice Improvement Act reforms to the preliminary hearing process under Article 32, clarifying the role and authority of preliminary hearing officers.
Significance
Clarified the scope of the reformed Article 32 preliminary hearing process, impacting how serious charges are screened before referral to general courts-martial.
United States v. Barry
78 M.J. 70 (C.A.A.F. 2018)
CAAF held that a military judge's failure to instruct the panel on a lesser included offense of assault when evidence supported it constituted reversible error, requiring a new trial on the affected charge.
Significance
Reinforced the obligation of military judges to instruct on reasonably raised lesser included offenses, protecting the right of the accused to have the panel consider all appropriate charges.
Military Court System Overview
Courts-Martial
There are three types of courts-martial: (1) Summary courts-martial for minor offenses, presided over by a single officer; (2) Special courts-martial for intermediate offenses, with a military judge and panel; (3) General courts-martial for the most serious offenses, with a military judge and panel of at least eight members.
The Military Justice Improvement and Increasing Prevention Act (2023) transferred prosecution decisions for serious offenses from commanders to independent Special Trial Counsel, the most significant structural reform since the UCMJ's enactment.
Appellate Structure
Each service branch has a Court of Criminal Appeals (Army, Navy- Marine Corps, Air Force, Coast Guard) that automatically reviews serious convictions. Above these sits the Court of Appeals for the Armed Forces (CAAF), a civilian Article I court composed of five judges appointed by the President.
Further review is available by petition for certiorari to the U.S. Supreme Court, which has the discretion to hear military justice cases. This final layer of civilian review ensures military justice aligns with constitutional standards.
Non-Judicial Punishment
Article 15 authorizes commanders to impose non-judicial punishment (NJP) for minor offenses without a formal court-martial. Known as “Captain's Mast” in the Navy and Coast Guard, “Office Hours” in the Marine Corps, and “Article 15” in the Army and Air Force.
Punishments may include extra duties, restriction, reduction in grade, and forfeiture of pay. Except aboard vessels, service members have the right to refuse NJP and demand trial by court-martial.
Military Rules of Evidence
The Military Rules of Evidence (MRE) govern the admissibility of evidence in courts-martial proceedings. They are largely based on the Federal Rules of Evidence but include military-specific provisions, such as those addressing classified information, command influence, and the unique Article 31 rights warning.
Notable differences include MRE 304 (addressing military- specific confession requirements), MRE 311 (search and seizure rules reflecting military living conditions), and MRE 513 (psychotherapist-patient privilege with military exceptions).
