Article 43 of the UCMJ establishes the time limits within which charges must be preferred against a servicemember. The general limitation period is five years for most offenses, but certain serious crimes carry no statute of limitations.
General Statute of Limitations
Article 43 provides a general five-year statute of limitations for most UCMJ offenses. Charges must be preferred (formally sworn) within five years of the commission of the offense. This period begins when the offense is complete and runs until the charges are sworn, not until they are referred or tried.
Offenses with No Statute of Limitations
Several categories of offenses have no statute of limitations under military law. These include any offense punishable by death (such as murder, espionage, and certain wartime offenses), absence without leave or missing movement in time of war, and sexual offenses covered by Articles 120, 120b, 120c, and 125 of the UCMJ.
Congress has progressively extended or eliminated limitations periods for sexual offenses through a series of legislative actions reflecting the unique reporting challenges those cases present. Sexual assault victims frequently delay reporting for months or years due to trauma, fear of retaliation, concerns about career impact, and the power dynamics inherent in military command structures. The military’s restricted reporting system, which allows victims to access medical care and counseling without triggering an investigation, can further delay the transition to an unrestricted report that initiates the investigative process. The elimination of the statute of limitations for sexual offenses ensures that prosecutions remain available regardless of the length of this reporting delay.
Tolling Provisions
The statute of limitations is tolled (paused) during periods when the accused is absent without authority, fleeing from justice, outside the territory where the United States has authority to apprehend, in the custody of civil authorities, or in the hands of the enemy. These tolling provisions prevent an accused from evading prosecution by placing themselves beyond the military’s reach.
War vs. Peace
The statute of limitations may differ between time of war and time of peace for certain offenses. AWOL and missing movement, for example, have no statute of limitations in time of war. The determination of whether the nation is at “war” for these purposes follows the UCMJ’s definition, which may include both formally declared wars and other conflicts.
Discovery Rule
For certain offenses, the statute of limitations may begin to run from the date the offense was “discovered” rather than the date it was committed. Military courts apply this discovery rule in situations where the offense was concealed or its criminal nature was not immediately apparent. The determination of when an offense was discovered involves a fact-specific inquiry.
Waiver or Extension
The statute of limitations is generally considered a substantive right that cannot be waived by agreement of the parties. However, the accused may waive the statute of limitations defense if they choose not to raise it. The military judge will not raise the statute of limitations sua sponte if the defense does not assert it.
DNA Evidence and Cold Cases
Advances in forensic technology, particularly DNA analysis, have created situations where evidence becomes available long after an offense was committed. For offenses with no statute of limitations (such as murder and sexual assault), DNA evidence can be used to prosecute cold cases regardless of the passage of time.
Military cold case investigations benefit from the military’s long-term retention of personnel records, DNA samples collected from servicemembers (maintained by the Armed Forces Medical Examiner System for identification purposes), and digital records that may corroborate or contradict alibis and timelines. DNA collected from crime scenes or sexual assault forensic examinations may be preserved for decades and later matched to suspects through expanded databases, including the Combined DNA Index System (CODIS) maintained by the FBI. The OSTC’s reach-back authority, which allows independent prosecutors to take over cases predating the OSTC’s establishment, provides an additional mechanism for revisiting older cases that may benefit from new forensic evidence or a fresh prosecutorial assessment.
Continuing Offenses
Some offenses are considered “continuing” offenses that span a period of time. For continuing offenses, the statute of limitations begins to run when the offense terminates, not when it begins. If a continuing offense spans the limitations boundary, the prosecution may charge the portion of the offense that falls within the limitations period.
