23A-7-2. (Rule 11(a)) Pleas permitted to defendant--Requirements for plea of guilty or nolo contendere.

A defendant may plead:

(1)    Not guilty;

(2)    Not guilty and not guilty by reason of insanity;

(3)    Guilty;

(4)    Nolo contendere; or

(5)    Guilty but mentally ill.

Except as otherwise specifically provided, a plea of guilty or nolo contendere can only be entered by a defendant himself in open court. If a defendant refuses to plead, or if the court refuses to accept a plea of guilty or nolo contendere, the court shall enter a plea of not guilty. The court may not enter a judgment unless it is satisfied that there is a factual basis for any plea except a plea of nolo contendere.
