Panel members in a court-martial serve a role analogous to jurors in civilian trials, determining guilt or innocence and, if convicted, the sentence. However, the selection process differs fundamentally from civilian jury selection.
Selection Criteria Under Article 25
The convening authority personally selects panel members based on statutory criteria specified in Article 25 of the UCMJ: age, education, training, experience, length of service, and judicial temperament. The convening authority is directed to select those members best qualified by these criteria. Recent reforms have introduced randomization requirements to reduce the appearance of hand-picking favorable panels.
Panel members must be on active duty and senior in rank to the accused (unless an enlisted accused requests enlisted members). Officers from any branch may serve, and members need not be from the same unit or installation as the accused.
Enlisted Panel Members
An enlisted accused may request that enlisted members be included on the panel. When this request is made, at least one-third of the panel must be enlisted members. Enlisted panel members must be senior in rank to the accused. The convening authority selects enlisted members using the same Article 25 criteria applied to officer members.
Challenges for Cause
Both the prosecution and defense may challenge panel members for cause. A challenge for cause is based on a specific ground of disqualification, such as actual or implied bias, a personal relationship with a party or witness, prior knowledge of the case, or a command relationship that could affect impartiality. The military judge decides challenges for cause.
The standard for removal is whether the member’s participation would raise a substantial doubt about the fairness of the proceeding in the mind of a reasonable person.
Peremptory Challenges
Each side receives one peremptory challenge per case under R.C.M. 912(g). A peremptory challenge allows a party to remove a panel member without stating a reason. This is significantly fewer peremptory challenges than typically available in civilian criminal trials, where each side may receive several. The limited number of peremptory challenges in courts-martial places greater weight on the challenge-for-cause process and makes each peremptory challenge a strategic decision that defense and trial counsel must use carefully.
Minimum Panel Size
A general court-martial requires a minimum of eight panel members under Article 16 of the UCMJ as amended by the MJA16. A special court-martial requires a minimum of four members. For capital cases, at least 12 members are required. If the panel falls below the minimum size due to excusals or challenges, additional members must be detailed by the convening authority before the trial can proceed. The military judge monitors panel composition throughout the trial and will halt proceedings if the panel drops below the required minimum.
Deliberation and Voting
Panel members deliberate in closed session. Voting on findings (guilty or not guilty) and on sentencing is by secret written ballot. Conviction at a general court-martial requires a three-fourths vote of the members present. A death sentence requires a unanimous vote. Sentencing for non-capital offenses requires a three-fourths vote for a sentence involving confinement of more than ten years, and a two-thirds vote for other sentences.
Panel Misconduct
If a panel member engages in misconduct, such as conducting outside research, discussing the case with non-panel members, or considering extraneous information, the military judge must investigate the matter. Depending on the severity of the misconduct, the judge may instruct the panel to disregard the extraneous information, excuse the affected member, or declare a mistrial.
Junior-Ranking Panel Members
Panel members must generally be senior in rank to the accused under Article 25 of the UCMJ. A panel member who is junior in rank to the accused may not serve, and the inclusion of a junior-ranking member may constitute a jurisdictional error subject to appellate review. The convening authority is responsible for verifying rank eligibility when detailing members. If a junior-ranking member is discovered after the trial has begun, the military judge must address the issue, which may require excusing the member or, if the error affected the verdict, ordering a new trial. When enlisted members are requested by an enlisted accused, those enlisted panel members must also be senior to the accused.
