Defendant was convicted by a jury of two counts of firs't-deg'ree murder (MCLA 750.316; MSA 28.548). Prior to his trial, defendant’s attorneys moved to have him committed in order that his competency to stand trial be determined as provided by GCR 1963, 786.3. The court originally ordered such a commitment, but subsequently amended its order to provide that defendant be examined by a local clinical psychologist, the purpose being to determine whether commitment to a diagnostic facility was necessary to determine defendant’s competency.
We feel the judge’s actions in this regard were erroneous and reversible. The court rule (GCR 1963, 786.3) is mandatory. Whenever there is any question as to a defendant’s competency to stand trial, and that question is raised upon defendant’s motion, the court “shall” order the defendant com*664mitted to a diagnostic facility. People v Ledbetter, 31 Mich App 160 (1971).
Reversed and remanded for commitment to a diagnostic institution and for a new trial.
All concurred.
