(A) During Jury Trial. If, by reason of death, sickness, or other disability, the judge before whom a jury trial has commenced is unable to continue with the trial, another judge regularly sitting in or assigned to the court, on certification of having become familiar with the record of the trial, may proceed with and complete the trial.
(B) During Bench Trial. If a judge becomes disabled during a trial without a jury, another judge may be substituted for the disabled judge, but only if
(1) both parties consent in writing to the substitution, and
(2) the judge certifies having become familiar with the record of the trial, including the testimony previously given.
(C) After Verdict. If, after a verdict is returned or findings of fact and conclusions of law are filed, the trial judge because of disability becomes unable to perform the remaining duties the court must perform, another judge regularly sitting in or assigned to the court may perform those duties; but if that judge is not satisfied of an ability to perform those duties because of not having presided at the trial or determines that it is appropriate for any other reason, the judge may grant the defendant a new trial.
