Mo. R. Crim. P. 32.15
As amended through November 19, 2024
If by reason of his going out of office, death, sickness, or other disability, a judge before whom an action has been tried is unable to perform the duties to be performed by the court under these Rules after a verdict is returned or findings of fact are filed, then any other judge sitting in or assigned to the court in which the criminal proceeding was tried may perform those duties; but if such other judge is satisfied that he cannot perform those duties because he did not preside at the trial or for any other reason, he may in his discretion grant a new trial.
