If an accused in a military commission under this chapter after a plea of guilty sets up matter inconsistent with the plea, or if it appears that the accused has entered the plea of guilty through lack of understanding of its meaning and effect, or if the accused fails or refuses to plead, a plea of not guilty shall be entered in the record, and the military commission shall proceed as though the accused had pleaded not guilty.

With respect to any charge or specification to which a plea of guilty has been made by the accused in a military commission under this chapter and accepted by the military judge, including a charge or specification that has been referred capital, a finding of guilty of the charge or specification may be entered by the military judge immediately without a vote by the members. The finding shall constitute the finding of the military commission unless the plea of guilty is withdrawn prior to announcement of the sentence, in which event the proceedings shall continue as though the accused had pleaded not guilty.
