How Does the Statute of Limitations Operate Under the UCMJ?

A statute of limitations is a deadline. Miss it, and the government loses the power to prosecute no matter how strong its proof. In the military justice system that deadline lives in Article 43 of the Uniform Code of Military Justice (10 U.S.C. 843), and two features of it surprise people who assume it works like a civilian filing deadline. First, the clock does not stop when a case is opened, when a commander decides to pursue charges, or when a trial begins. It stops at a precise, earlier moment in the paperwork. Second, an entire tier of the most serious offenses sits outside the deadline altogether and can be tried decades later. Understanding which rule applies, and exactly when the clock stops, is what separates a viable prosecution from one that is time-barred.

The default rule: five years to receipt of sworn charges

For most UCMJ offenses, the limitation period is five years. The detail that trips people up is the event that stops the clock. Under Article 43(b)(1), an accused cannot be tried by court-martial if the offense was committed more than five years before “the receipt of sworn charges and specifications by an officer exercising summary court-martial jurisdiction over the command.”

Parse that phrase, because each part carries weight. “Sworn charges” means the charges have been formally preferred and sworn under oath, the step governed by Rule for Courts-Martial 307. “Receipt by an officer exercising summary court-martial jurisdiction” identifies a specific person in the command who must physically receive that sworn charge sheet. The clock stops on that receipt, not on referral to a court-martial, not on arraignment, and not on the first day of trial. Those later events can fall well outside five years, and the case is still timely, so long as the sworn charges reached the right officer inside the window.

The practical consequence is that the limitations question turns on a date stamp deep in the charging process rather than on when the courtroom doors open. A case can be preferred at four years and eleven months, sit through an Article 32 preliminary hearing, and be tried at six years, and still be within the statute. Conversely, an investigation that drags until the sworn charges arrive at five years and one day is barred, even if everyone knew about the conduct from the start.

The offenses with no time limit at all

A category of offenses can be tried “at any time without limitation.” This is the part of Article 43 that has changed the most over the past two decades, as Congress repeatedly widened it, so the current list matters more than any historical version of it.

Under Article 43(a), there is no limitation period for:

Absence without leave or missing movement in time of war
Murder
Rape or sexual assault
Rape or sexual assault of a child
Maiming of a child
Kidnapping of a child
Any other offense punishable by death

The unifying logic is that the no-limitation tier is defined by the character of the offense, not by a fixed list of article citations. Rape and sexual assault of an adult fall under Article 120, and the child counterparts fall under Article 120b, so a sexual-offense prosecution under those articles is effectively unbounded in time. But the statute reaches the conduct by name. An offense “punishable by death,” for instance, sweeps in espionage and certain wartime offenses whenever the death penalty is authorized for them, regardless of which article number carries the charge.

There is a second, distinct rule for child abuse that is broader than the ordinary five years but narrower than “no limit.” Under Article 43(b)(2), a child abuse offense that is not already covered by the no-limitation tier can be tried if the sworn charges are received during the life of the child or within ten years after the offense, whichever period is longer. The statute defines “child abuse offense” to include enumerated offenses, such as certain assaults under Article 128, committed against a person under a set age, so it captures serious mistreatment of children that would not otherwise carry the unlimited window reserved for sexual offenses and homicide.

Why the clock stops without finishing: tolling

Even when an offense carries a deadline, certain periods do not count toward it. Article 43 excludes, or tolls, the time during which an accused is absent without authority or fleeing from justice, and the time the accused is absent from any territory in which the United States has authority to apprehend, in the custody of civil authorities, or in the hands of the enemy. The purpose is straightforward: a service member cannot run out the clock by deserting, fleeing abroad, or otherwise placing themselves beyond the military’s reach. Those days are subtracted, so the five years is five years of available prosecution time, not five years on the calendar.

Article 43 also contains wartime and DNA-driven extensions that broaden the picture further. Periods of war or declared hostilities can suspend the running of limitations for fraud and certain property and war-related offenses, deferring the deadline until a set time after hostilities end. And where DNA testing later implicates an identified person in an offense punishable by more than one year of confinement, the statute allows the prosecution window to extend by an additional period equal to the offense’s normal limitation period, measured from the DNA identification. That provision is what allows a cold case to move forward when forensic evidence puts a name to old physical evidence years after the fact.

A worked timeline

Consider a hypothetical to see how the pieces interact. Suppose conduct occurs in January 2020. If it is an ordinary five-year offense, the sworn charges must reach the summary-court-martial-jurisdiction officer by January 2025 for the case to proceed. If the suspect deserts for eight months during that span, those eight months are excluded, pushing the effective deadline to roughly September 2025. If the same January 2020 conduct were a sexual assault under Article 120, none of that arithmetic would matter, because the offense carries no limitation and could be charged years later. And if the suspect’s identity were unknown until a 2026 DNA match on preserved evidence from a confinement-eligible offense, the DNA provision could keep the window open even on an offense that would otherwise have expired. The same calendar date produces three very different answers depending on which rule governs.

The defense the court will not raise on its own

A point of military procedure worth isolating: the statute of limitations operates as a defense that the accused must assert. A military judge will generally not raise it on the court’s own initiative if the defense does not. In practice this means a limitations bar is something to be identified and invoked, and the failure to raise it can forfeit it, which is a different posture from a jurisdictional defect that the court must police regardless of the parties. The distinction matters because it reframes the deadline from an automatic shield into a defense that has to be put on the record.

How this differs from a civilian deadline

The military framework rhymes with civilian criminal statutes of limitations but is not identical. Civilian systems also exempt murder and many sexual offenses from any limitation and toll for flight, but the military’s anchor on “receipt of sworn charges by an officer exercising summary court-martial jurisdiction” is a service-specific trigger with no civilian equivalent. Treating Article 43 as if it tracked a state criminal code, where the deadline is often the date of indictment or arrest, is the most common analytical mistake, and it points at the wrong event in the timeline.
