A. If by reason of death, sickness or other disability, the Judge before whom a jury has commenced is unable to proceed with the trial, any other Trial Judge may, upon certifying that he or she has familiarized himself or herself with the record of the trial, proceed with the trial.

B. If by reason, of death, sickness or other disability, the Judge before whom the defendant has been tried is unable to perform the required duties of a Judge after the verdict or finding of guilt, any other Trial Judge may perform those duties unless such Judge feels he cannot fairly perform those duties in which case a new trial may be granted. A new trial shall not be granted if all that remains to be done is the sentencing of a defendant.
