Primary members of a military commission under this chapter are voting members.

Whenever the number of primary members of a military commission under this chapter is reduced below the number of primary members required by subsection (a) and there are no remaining alternate members to replace the excused primary members, the trial may not proceed unless the convening authority details new members sufficient to provide not less than such number. The trial may proceed with the new members present after the recorded evidence previously introduced before the members has been read to the military commission in the presence of the military judge, the accused (except as provided in section 949d of this title), and counsel for both sides. An alternate member who was present for the introduction of all evidence shall not be considered to be a new or additional member.
