RULE 63                                                
                           JUDGES                                                
                                                                                 
    (a) Powers. See rule 77.                                                     
    (b) Disability of a Judge. If by reason of 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 and conclusions of law are filed,        
then any other judge regularly sitting in or assigned to the court in which      
the action 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.
