Mich. Ct. R. 2.630 (2026)

If, after a verdict is returned or findings of fact and conclusions of law are filed, the judge before whom an action has been tried is unable to perform the duties prescribed by these rules because of death, illness, or other disability, another judge regularly sitting in or assigned to the court in which the action was tried may perform those duties. However, if the substitute judge is not satisfied that he or she can do so, the substitute judge may grant a new trial.
