Mental Responsibility and Competency to Stand Trial
Mental responsibility is the criminal culpability of the defendant based on his or her mental state at the time of the offense and includes the “insanity defense” and the defense of “partial mental responsibility.”
Competency to Stand Trial
Competency to stand trial refers to the present ability of the defendant to stand trial. An accused may not be tried unless mentally competent. Godinez v. Moran, 509 U.S 389, 396 (1993). To try a mentally incompetent accused is a violation of due process. Medina v. California, 505 437, 453 (1992).
