As amended through April 3, 2024
Rule 6.304 - Plea of Not Guilty by Reason of Insanity
(A) Advice to Defendant. Before accepting a plea of not guilty by reason of insanity, the court must comply with the requirements of MCR 6.302 except that subrule (C) of this rule, rather than MCR 6.302(D), governs the manner of determining the accuracy of the plea.
(B) Additional Advice Required. After complying with the applicable requirements of MCR 6.302, the court must advise the defendant, and determine whether the defendant understands, that the plea will result in the defendant's commitment for diagnostic examination at the center for forensic psychiatry for up to 60 days, and that after the examination, the probate court may order the defendant to be committed for an indefinite period of time.
(C) Factual Basis. Before accepting a plea of not guilty by reason of insanity, the court must examine the psychiatric reports prepared and hold a hearing that establishes support for findings that
(1) the defendant committed the acts charged, and
(2) that, by a preponderance of the evidence, the defendant was legally insane at the time of the offense.
(D) Report of Plea. After accepting the defendant's plea, the court must forward to the center for forensic psychiatry a full report, in the form of a settled record, of the facts concerning the crime to which the defendant pleaded and the defendant's mental state at the time of the crime.
