A court-martial trial follows a structured sequence that parallels civilian criminal trials in many respects but incorporates military-specific procedures at each stage. The process moves from arraignment through motions practice, presentation of evidence, deliberation, and a bifurcated sentencing phase. Procedural errors at any stage can become grounds for appellate reversal.
Arraignment
The court-martial trial begins with the arraignment, during which the accused is formally advised of the charges and specifications and asked to enter pleas. The military judge verifies the accused’s identity, confirms the presence of counsel, and addresses preliminary matters including the accused’s election of trial by judge alone or by panel members.
During arraignment, the military judge also addresses any known pretrial matters, including the accused’s right to counsel, the composition of the panel (if applicable), and any pending motions.
Motions Practice
Before the presentation of evidence, the military judge hears and rules on pretrial motions. These may include motions to suppress evidence (challenging the legality of searches, seizures, or confessions obtained in violation of Article 31 or the Fourth Amendment), motions to dismiss charges (for lack of jurisdiction, failure to state an offense, violation of speedy trial rights under R.C.M. 707, or unlawful command influence), motions regarding the admissibility of specific evidence (such as prior sexual behavior under MRE 412 or classified information under MRE 505), and motions for appropriate relief addressing other legal defects.
The military judge’s rulings on motions are critical to the trial’s outcome and are frequently the subject of appellate review. A ruling excluding a key confession or physical evidence may effectively end the prosecution’s case. Rulings on the admissibility of evidence and the sufficiency of the charges shape what the factfinder will consider. The defense typically raises as many potentially dispositive motions as possible before the trial on the merits begins, as prevailing on a single suppression or dismissal motion may resolve the case without the need for a contested trial.
Opening Statements, Evidence, and Closing Arguments
After pretrial matters are resolved, the trial proceeds with opening statements from the prosecution and defense. The prosecution then presents its case-in-chief through witness testimony and documentary evidence, all subject to cross-examination by the defense. After the prosecution rests, the defense may present its own case, though the defense is not required to present any evidence.
Rebuttal and surrebuttal evidence may follow. After all evidence is presented, both sides deliver closing arguments. The prosecution argues first, the defense responds, and the prosecution has the right to a final rebuttal argument.
Instructions to the Panel
Before deliberations, the military judge instructs the panel on the law applicable to the case. Instructions cover the elements of each offense, the presumption of innocence, the burden of proof, the standard of proof beyond a reasonable doubt, the treatment of various types of evidence, and any specific legal issues raised during the trial (such as defenses or lesser included offenses).
The instructions are crafted from standardized benchbooks maintained by each service’s judiciary, with modifications to fit the specific case.
Victim Impact Statements
Under the Victim and Witness Assistance Program and subsequent legislative reforms, victims of offenses have the right to submit victim impact statements. These statements may be presented during the sentencing phase (after a finding of guilty) and inform the court about the impact of the offense on the victim.
Voting Requirements for Conviction
Conviction at a general court-martial by panel members requires the concurrence of three-fourths of the members present and voting. This differs from civilian criminal trials, which generally require a unanimous verdict from all jurors. For offenses carrying a mandatory minimum sentence of more than ten years of confinement, unanimity is required. A death sentence requires a unanimous vote by all panel members. In a judge-alone trial, the military judge makes the finding independently.
Bifurcated Sentencing
After a finding of guilty, the trial enters a separate sentencing phase. Both sides present evidence relevant to sentencing, including the accused’s service record, personal history, the nature of the offense, and aggravating and mitigating circumstances. The accused has the unique right to make an unsworn statement that cannot be cross-examined. The panel or military judge then deliberates and adjudges the sentence.
For offenses committed after December 27, 2023, the FY2022 NDAA requires that the military judge alone determines the sentence in all non-capital cases. This eliminated the accused’s prior option to elect sentencing by panel members. The military judge applies sentencing parameters and criteria established in the 2024 Manual for Courts-Martial, which provide confinement ranges tied to offense severity. The judge may depart from these ranges only upon making specific findings justifying the departure. This reform fundamentally changed the sentencing phase from a discretionary proceeding to a more structured determination, though judicial discretion remains significant within and around the established parameters.
