(A) Applicable Provisions. Except as provided in these rules, a mental competency hearing in a criminal case is governed by MCL 330.2020 et seq.
(B) Time and Form of Motion. The issue of the defendant’s competence to stand trial or to participate in other criminal proceedings may be raised at any time during the proceedings against the defendant. The issue may be raised by the court before which such proceedings are pending or being held, or by motion of a party. Unless the issue of defendant’s competence arises during the course of proceedings, a motion raising the issue of defendant’s competence must be in writing. If the competency issue arises during the course of proceedings, the court may adjourn the proceeding or, if the proceeding is defendant's trial, the court may, consonant with double jeopardy considerations, declare a mistrial.
(C) Order for Examination.
(1) On a showing that the defendant may be incompetent to stand trial, the court must order the defendant to undergo an examination by a certified or licensed examiner of the center for forensic psychiatry or other facility officially certified by the department of mental health to perform examinations relating to the issue of competence to stand trial.
(2) The defendant must appear for the examination as required by the court.
(3) If the defendant is held in detention pending trial, the examination may be performed in the place of detention or the defendant may be transported by the sheriff to the diagnostic facility for examination.
(4) The court may order commitment to a diagnostic facility for examination if the defendant fails to appear for the examination as required or if commitment is necessary for the performance of the examination.
(5) The defendant must be released from the facility on completion of the examination and, if (3) is applicable, returned to the place of detention.
(D) Independent Examination. On a showing of good cause by either party, the court may order an independent examination of the defendant relating to the issue of competence to stand trial.
(E) Hearing. A competency hearing must be held within 5 days of receipt of the report required by MCL 330.2028 or on conclusion of the proceedings then before the court, whichever is sooner, unless the court, on a showing of good cause, grants an adjournment.
(F) Motions; Testimony.
(1) A motion made while a defendant is incompetent to stand trial must be heard and decided if the presence of the defendant is not essential for a fair hearing and decision on the motion.
(2) Testimony may be presented on a pretrial defense motion if the defendant’s presence could not assist the defense.
