The United States and Pakistan each maintain a distinct system of military law for their armed forces, but the two systems sit in very different constitutional and political settings. The American system is consolidated in a single congressional statute, the Uniform Code of Military Justice, enforced through commander-convened courts-martial with civilian appellate review. The Pakistani system is grounded in the Pakistan Army Act of 1952 and parallel service legislation, enforced through military courts, and it has become internationally prominent because of a recurring and deeply contested practice: the trial of civilians before military courts. Comparing the two highlights not only structural differences but a sharp divergence over who may be subjected to military justice at all.
The American framework: the UCMJ and courts-martial
In the United States, military law is consolidated in the Uniform Code of Military Justice, or UCMJ, enacted by Congress and codified in Title 10 of the United States Code. The UCMJ governs members of all the armed forces and contains both military-specific offenses, such as desertion and disobedience of a lawful order, and ordinary crimes, such as theft, assault, and murder, that can be tried under military jurisdiction.
The UCMJ is implemented through the Manual for Courts-Martial, a presidential document supplying the Rules for Courts-Martial and the Military Rules of Evidence. Article 16 sets out three tiers of court-martial, summary, special, and general. A general court-martial consists of a military judge and a panel of members, with the accused entitled to elect a judge-alone trial. The 2016 Military Justice Act, reflected in the 2019 edition of the Manual, fixed statutory panel sizes and modernized voting and sentencing.
A foundational principle of the American system is that, as a general rule, military jurisdiction reaches service members rather than civilians. The Supreme Court has sharply limited the circumstances in which civilians may be subjected to court-martial. The American system is administered internally by the military, applies jurisdiction based on military status, and provides appellate review through the service Courts of Criminal Appeals to the civilian Court of Appeals for the Armed Forces, with possible Supreme Court review.
The Pakistani framework: the Army Act and military courts
Pakistan’s military law for its army is grounded in the Pakistan Army Act of 1952, enacted by Parliament as the primary statute governing the affairs of the Pakistan Army, with parallel acts for the air force and the navy. The Army Act defines military offenses and provides for trial by military courts. Proceedings are conducted under the supervision of the military’s legal branch, the office of the Judge Advocate General, and military courts such as the Field General Court Martial are presided over and prosecuted by serving military officers.
In its core operation, the Pakistan Army Act resembles other common-law-derived military codes: it disciplines members of the armed forces for military offenses, provides several types of court-martial, and operates through a JAG-supervised structure. Had the system stopped there, it would invite a fairly conventional comparison with the UCMJ. What sets Pakistan apart, and what has drawn sustained domestic and international attention, is the extent to which its military courts have been used to try civilians.
The defining contrast: trial of civilians
The most significant divergence between the American and Pakistani systems concerns who can be tried by a military court.
The American rule, reinforced by Supreme Court decisions, is that civilians are generally not subject to court-martial, and the reach of military jurisdiction over civilians is narrow and contested even at its edges. Military justice in the United States is, in principle, for those in uniform.
Pakistan has taken a markedly different path. The Pakistan Army Act was amended decades ago to extend its application to certain civilians, such as those accused of inciting mutiny or interfering with the armed forces. The scope expanded dramatically through the Constitution (Twenty-First Amendment) Act of 2015 and accompanying amendments to the Army Act, which authorized the establishment of military courts to try civilians suspected of terrorism, enacted in the aftermath of a major terrorist attack. To shield these arrangements from challenge, the Pakistan Army Act was placed in a constitutional schedule, and the courts established under that amendment operated under a time limit, with the arrangement later extended through a further constitutional amendment in 2017.
The constitutionality of trying civilians before military courts has been litigated at the highest level in Pakistan. A full bench of the Supreme Court of Pakistan, sitting with seventeen judges, upheld the Twenty-First Amendment by a divided vote of eleven to six, reflecting deep disagreement on the bench itself. The practice has remained legally and politically contentious, has been criticized by human rights organizations on fair-trial grounds, and has been the subject of continued litigation. Because this area has been repeatedly amended and relitigated, readers should treat the current legal status of civilian military trials in Pakistan as unsettled and subject to change.
Independence, fair-trial concerns, and oversight
The two systems also differ in their structures for safeguarding fairness.
The American system, while keeping military justice within the chain of command, builds in tenured military judges during trials, independent defense counsel, statutory prohibitions on unlawful command influence, mandatory appellate review for serious cases, and a civilian appellate court at the top, with recent reform shifting certain serious prosecution decisions to independent special trial counsel.
In the Pakistani military courts, by contrast, critics have raised concerns that the proceedings, particularly those involving civilians, may not provide the full range of fair-trial protections found in ordinary courts, pointing to features such as officers serving as both judges and prosecutors and limits on transparency. These concerns are central to the international criticism of the system. Pakistan’s superior courts, principally the Supreme Court and the High Courts, retain a constitutional role and have at times reviewed military court matters, so judicial oversight exists, but its scope and effectiveness in the military-court context have themselves been the subject of debate.
Appeals and ultimate review
In the United States, appeals run from a service Court of Criminal Appeals to the Court of Appeals for the Armed Forces and possibly to the Supreme Court, a structured ladder culminating in civilian review.
In Pakistan, military court decisions have been subject to internal confirmation processes within the military hierarchy and to a contested degree of review by the constitutional courts. The availability and depth of meaningful appellate review, especially for civilians convicted by military courts, has been one of the principal points of legal contention and remains an evolving question.
What the comparison reveals
Set side by side, the two systems share a common-law-influenced structure of statutory military offenses and multiple types of court-martial, but they diverge fundamentally on the question that matters most: the proper reach of military justice. The United States confines court-martial jurisdiction largely to service members and surrounds the system with civilian appellate safeguards. Pakistan, responding to its security situation and through constitutional amendment, extended military court jurisdiction to civilians accused of terrorism, a step that produced a divided Supreme Court ruling, persistent fair-trial criticism, and ongoing litigation.
For a comparative reader, Pakistan is the prominent modern example of the controversy that arises when military courts are used to try civilians. The American model answers the need for military discipline by keeping military justice focused on those in uniform and capping it with civilian review, while Pakistan presents the harder case of a democracy that, under the pressure of terrorism, expanded military jurisdiction into the civilian sphere in ways that remain constitutionally and internationally contested.

Military law also changes over time.
