Summary

The military judge must call and seat the members for a general or special court-martial. After any challenges are decided, the judge picks who will serve and excuses those not chosen. Once seated, members cannot leave unless they are excused for a challenge, under the rules, or by the judge or the officer who ordered the trial for disability or other good cause. The judge must seat 12 members for a general death‑penalty (capital) case, eight for a regular general case, and four for a special court-martial. Alternate members can be added if allowed. If numbers drop, the required minimums are 12 for capital, six to eight for noncapital general cases, and four for special courts. If the judge becomes unable to continue, a new judge must be assigned. New members may join and the trial can go on after the earlier testimony or recordings are read or played for the new members in the new judge’s presence, with the accused and both lawyers present. If a new judge takes over, the trial is treated as if no evidence had been given unless the prior evidence is read or played in front of the new judge, the accused, and the lawyers.

In subsections (a), (b), and (c), the word “may” is substituted for the word “shall”. In subsections (b) and (c), the word “details” is substituted for the word “appoints”, since the filling of the position involved is not appointment to an office in the constitutional sense.
