(a) The judge or jury shall determine that a defendant is not guilty by reason of insanity if:
(1) the prosecution has established beyond a reasonable doubt that the alleged conduct constituting the offense was committed; and
(2) the defense has established by a preponderance of the evidence that the defendant was insane at the time of the alleged conduct.
(b) The parties may, with the consent of the judge, agree to both:
(1) dismissal of the indictment or information on the ground that the defendant was insane; and
(2) entry of a judgment of dismissal due to the defendant's insanity.
(c) An entry of judgment under Subsection (b)(2) has the same effect as a judgment stating that the defendant has been found not guilty by reason of insanity.
