Inability to Hear Post-Conviction Motions

If by reason of absence, death, sickness or other disability the judge before whom the defendant has been tried is unable to perform the duties to be performed by the court after a verdict or finding of guilt any other judge regularly sitting or assigned to the court 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.
