Service members sometimes assume that being on leave puts them beyond the reach of military justice. It does not. Leave is an authorized absence from duty, but it is not a release from military status, and military status is what court-martial jurisdiction turns on. When a jurisdictional challenge is raised in a case where the offense happened during leave, the military judge resolves it primarily by examining the accused’s status at the time of the offense, not the location or the off-duty nature of the act. The analysis follows a fairly settled framework, and walking through it shows why “I was on leave” is rarely a jurisdictional defense.
The controlling principle: status, not service connection
The decisive question is whether the accused was a member of the armed forces subject to the Uniform Code of Military Justice (UCMJ) when the offense occurred. In Solorio v. United States, 483 U.S. 435 (1987), the Supreme Court held that court-martial jurisdiction depends solely on the accused’s status as a member of the armed forces and not on whether the offense is connected to military service. Solorio overruled the earlier service-connection test, which had asked whether the crime had a sufficient nexus to the military. After Solorio, the inquiry is simpler and broader: if the accused had military status at the time of the offense, the court-martial generally has jurisdiction over the person, regardless of where the act took place or whether it occurred during off-duty time.
This is why being on leave does not strip jurisdiction. A member on leave remains on active duty and retains military status. Leave changes the member’s duty obligations, not the member’s membership in the armed forces.
How personal jurisdiction is established
Personal jurisdiction under Article 2 of the UCMJ rests on the accused being within a category subject to the code, most commonly a member on active duty. To resolve a challenge, the military judge examines the basis for status: a valid enlistment or commission, continued active-duty membership, and the absence of a proper discharge that would have ended status before the offense. If those facts hold, the member was subject to the UCMJ during leave, and personal jurisdiction exists.
Where status is genuinely contested, the issue is litigated as a question for the military judge. The government bears the burden of establishing jurisdiction by a preponderance of the evidence. Because leave does not interrupt status, a member on authorized leave will almost always be found to have remained subject to the code.
Subject-matter jurisdiction over the offense
Jurisdiction also requires that the charged conduct be an offense under the UCMJ tried by a properly convened court-martial. After Solorio, there is no separate requirement that an offense committed during leave be service-connected. If the conduct violates a punitive article of the UCMJ, it can be charged, even if it occurred far from any installation, in the member’s hometown, and entirely on personal time. The court-martial must itself be properly convened and the charges properly referred, which is a separate inquiry from whether the offense qualifies.
The recurring leave-specific arguments and why they usually fail
Several arguments tend to surface when an offense happens on leave, and the framework above explains how each is resolved.
The first is the geography argument, that the offense occurred off base or out of any military-controlled area. After Solorio, location is not the test for jurisdiction over a service member, so this argument does not defeat court-martial jurisdiction. It may bear on practical questions of overlapping civilian authority, but not on whether the military can proceed.
The second is the “off-duty” argument, that the member was not performing any military function. Leave is precisely an off-duty status, yet status as a member persists, so the absence of a duty connection does not remove jurisdiction.
The third is the civilian-jurisdiction argument, that a state or other sovereign also has authority over the conduct. Often both the military and a civilian jurisdiction have concurrent authority over an offense committed on leave, especially a civilian-side crime. Concurrent jurisdiction does not negate military jurisdiction; it simply means more than one authority may act, and questions of which proceeds first are typically handled through coordination rather than as a bar to court-martial.
When a jurisdictional challenge can actually succeed
Challenges do prevail in narrow situations, and they almost always concern status rather than the leave itself. If the member had already been validly discharged before the offense, military status may have ended, defeating jurisdiction. If the enlistment was so defective that status never attached, that can be litigated, although the constructive enlistment provision of Article 2(c) frequently preserves jurisdiction once the member voluntarily submitted to authority, met basic qualifications, received pay, and performed duties. And if the person was never subject to the code at all, jurisdiction fails. None of these turns on the offense occurring during leave; they turn on whether the accused was a service member when the offense happened.
How the issue is litigated procedurally
A jurisdictional challenge is typically raised by motion before trial. The military judge decides it, taking evidence on the facts of status if they are disputed. Because jurisdiction is fundamental, it can be raised at various stages and is not easily waived, and a conviction entered without jurisdiction is void. The judge applies the status test, considers the enlistment or commission and discharge records, and rules on whether the government has shown the accused was subject to the UCMJ at the relevant time.
Bottom line
When an offense occurs while a service member is on leave, jurisdictional challenges are resolved by asking whether the accused had military status at the time, not by asking whether the act was on duty, on base, or service-connected. Under Solorio, status alone supports court-martial jurisdiction over the person, and leave does not suspend status. The arguments that succeed are about whether the member was truly subject to the UCMJ, such as a prior valid discharge, rather than about the leave. For most members, an offense committed on leave is fully within the military’s reach.
