Chapter 24 - Mentally Ill Or Insane Defendants
Section 17-24-20. Guilty but mentally ill; general requirements for verdict.

(A) A defendant is guilty but mentally ill if, at the time of the commission of the act constituting the offense, he had the capacity to distinguish right from wrong or to recognize his act as being wrong as defined in Section 17-24-10(A), but because of mental disease or defect he lacked sufficient capacity to conform his conduct to the requirements of the law.
(B) To return a verdict of "guilty but mentally ill" the burden of proof is upon the State to prove beyond a reasonable doubt to the trier of fact that the defendant committed the crime, and the burden of proof is upon the defendant to prove by a preponderance of evidence that when he committed the crime he was mentally ill as defined in subsection (A).
(C) The verdict of guilty but mentally ill may be rendered only during the phase of a trial which determines guilt or innocence and is not a form of verdict which may be rendered in the penalty phase.
(D) A court may not accept a plea of guilty but mentally ill unless, after a hearing, the court makes a finding upon the record that the defendant proved by a preponderance of the evidence that when he committed the crime he was mentally ill as provided in Section 17-24-20(A).
