A court-martial panel is the military equivalent of a jury, and the law expects its members to be impartial. When a panel member has a preexisting professional relationship with someone connected to the case, such as the accused, a witness, an investigator, the trial counsel, or the convening authority, that connection can be grounds to remove the member. The standard that governs these challenges is found in the Rules for Courts-Martial, and it incorporates a distinctive feature of military practice that makes panel members easier to excuse than jurors in many civilian courts.
The basic mechanism: challenges for cause
Panel members are screened through voir dire, the structured questioning of members by the military judge, the trial counsel, and the defense. The tool for removing a member who cannot be impartial is the challenge for cause, governed by Rule for Courts-Martial (RCM) 912. Under RCM 912(f), a member must be excused for cause when it appears that the member should not sit in order to keep the court-martial free from substantial doubt as to its legality, fairness, and impartiality. A preexisting professional relationship is one of the circumstances that can support such a challenge, because it may create either an actual inability to be fair or an appearance of partiality.
The party raising the challenge, often the defense, identifies the relationship and argues that it disqualifies the member. The military judge then rules on whether the member should be removed.
Two kinds of bias: actual and implied
Military law recognizes two distinct theories under the challenge-for-cause framework, and a professional relationship can implicate either or both.
Actual bias is a subjective inquiry. It exists when the evidence shows that the member will not be impartial, that the member holds a personal bias that will not yield to the military judge’s instructions and to the evidence presented at trial. Actual bias is evaluated through the eyes of the military judge, who assesses the member’s credibility and state of mind, often based on the member’s answers during voir dire.
Implied bias is an objective inquiry. It exists when, regardless of the member’s own assurances of fairness, most people in the member’s position would be prejudiced, or when the circumstances would cause the public to question the fairness of the proceeding. Implied bias is viewed through the eyes of the public rather than through the member’s self-assessment. This is why a member who sincerely promises to be fair may still be removed: the question is not only whether the member believes he can be impartial, but whether a reasonable member of the public would doubt the fairness of allowing that member to sit.
A preexisting professional relationship frequently raises implied bias precisely because a member’s personal assurance may not dispel the public’s reasonable concern about a close working connection to a party or witness.
The liberal grant mandate
Military practice adds a thumb on the scale in favor of removal. Military judges are directed to apply a liberal grant mandate when ruling on challenges for cause raised by the accused. Under this mandate, in close cases the military judge should err on the side of granting the challenge, because the interests of justice are best served by resolving doubts about a member at the outset rather than risking an unfair proceeding. The rationale reflects the military’s historic sensitivity to the appearance of command influence and to public confidence in courts-martial.
The practical effect is significant. A professional relationship that might survive a challenge in some civilian settings can lead to removal in a court-martial, because the close-case tie goes to the accused. The liberal grant mandate does not eliminate the requirement to show a basis for the challenge, but it lowers the threshold for granting it once a genuine question of impartiality is presented.
How professional relationships are evaluated
When a professional relationship is the basis for the challenge, the analysis is fact-specific. Relevant considerations include how close and how current the relationship is, whether it involves a supervisory or subordinate dynamic, whether the connected person is central to the case, and whether the relationship touches the substance of the charges. A distant or purely incidental professional acquaintance may not raise a serious question, while a close or hierarchical relationship with a key witness or with the convening authority is far more likely to support removal under either the actual-bias or implied-bias theory. The military judge develops these facts through voir dire and then applies the standards, keeping the liberal grant mandate in mind for close calls.
Why the standard matters on appeal
The way a challenge is resolved can carry into appellate review. Because implied bias is judged objectively and the liberal grant mandate favors removal, appellate courts examine whether the military judge applied the correct standard and gave appropriate weight to the appearance of fairness. A failure to remove a member who should have been excused under these principles can become a ground for relief. This is part of why careful voir dire and a well-developed record on any professional relationship are so important at trial.
Conclusion
Challenges to court-martial panel members based on preexisting professional relationships are governed by RCM 912’s challenge-for-cause standard, which requires removal when needed to keep the proceeding free from substantial doubt as to its fairness and impartiality. The analysis recognizes both actual bias, judged subjectively through the member’s state of mind, and implied bias, judged objectively through the eyes of the public, and a professional relationship commonly raises the latter. The liberal grant mandate further instructs military judges to resolve close cases in favor of excusing the member. Because these determinations can affect both the fairness of the trial and the outcome on appeal, an accused who suspects a disqualifying relationship should ensure that experienced defense counsel develops the issue fully during voir dire.
