Section 130.45 - Pleas of the accused(a) If an accused after arraignment makes any irregular pleading, or after a plea of guilty sets up matter inconsistent with the plea, or if it appears that he has entered the plea of guilty improvidently or through lack of understanding of its meaning and effect, or if he fails or refuses to plead, a plea of not guilty shall be entered in the record and the court shall proceed as though he had pleaded not guilty.(b) With respect to any charge or specification to which a plea of guilty has been made by the accused and accepted by the military judge or by a court-martial without a military judge, a finding of guilty of the charge or specification may, if permitted by regulations issued pursuant to this chapter, be entered immediately without vote. This finding shall constitute the finding of the court unless the plea of guilty is withdrawn prior to announcement of the sentence, in which event the proceeding shall continue as though the accused had pleaded not guilty.
