Yes, a close social connection between a court-martial panel member and the accused can be grounds for a mandatory disqualification, a process known as a “challenge for cause.” The accused has a constitutional right to a fair and impartial panel. If a panel member’s relationship with the accused is so close that a reasonable person would question their ability to be impartial, they must be removed. This is essential to maintaining the integrity and fairness of the trial.
During the voir dire process, the defense attorney will question the panel members about any relationship they have with the accused. If a member reveals they are a close friend, a mentor, or have a significant social connection, the attorney will challenge them for cause. The legal standard is not whether the member thinks they can be fair, but whether the relationship creates an “appearance of unfairness.” A close friendship almost always meets this standard, as it implies a natural bias in favor of the accused.
While the defense wants a fair panel, they also want a favorable one, so they might not challenge a friendly member. However, the prosecutor would also have the right to challenge that same member for cause, arguing that their friendship with the accused makes them biased against the government. The military judge will make the final ruling. To protect the integrity of the verdict, a judge will almost always grant a challenge for cause when a close personal relationship exists between a panel member and the accused.
