Insanity Defense Amendments

HB 476 modifies Utah's insanity defense rules for first-degree and capital felony cases. It shifts the burden of proof to defendants claiming insanity, requiring them to prove their defense by "clear and convincing evidence." The bill also clarifies that certain conditions (like antisocial personality disorder or substance use disorders) cannot be used as insanity defenses, and updates procedures for mental health evaluations, supervision, and release of defendants found not guilty by reason of insanity. These changes directly affect criminal defendants in serious felony cases who may assert an insanity defense.
