5. If, for any reason, a case cannot be heard in the court room where it has been fixed for hearing, the master of the rolls, under the authority of the Chief Justice, shall refer it to another judge who is available, in such manner as will assure the greatest efficiency; if there is no judge available for either sitting on that day, the master of the rolls shall fix the case as soon as possible on a subsequent roll.
