This decision examines the quality of the defendant's decision. If the defendant appears to be intelligently and voluntarily waiving the insanity defense, the trial court should not deny this. However, the trial court should look into whether the defendant has been properly informed of the effects of their decision as well as the alternatives available to them. Thus the nature of such an evaluation would be similar to a competency to stand trial evaluation. The Frendak rationale, that a judge may not impose an insanity defense over the objections of the defendant, has been used mostly in federal cases. Some states have endorsed less elaborate procedures. For example, if a judge rules that the waiver of the insanity defense is not voluntary and informed, yet nonetheless the defense is imposed over the defendant's objections, then a separate counsel must be appointed to argue issues pertaining to insanity issues, while the defendant's counsel presents the arguments the defendant desires. Realistically, because of the Supreme Court's holding in
Godinez v. Moran, it is most likely that the court would hold that if a defendant is competent to stand trial, then he is also competent to waive the insanity defense, as the two competencies are equivalent.
Godinez v. Moran was modified and refined by the Supreme Court decision in
Indiana v. Edwards in 2008. ==See also==
