Rule 4316. Procedure where more than one referee. Where the reference is to more than one referee all must meet together and hear all the allegations and proofs of the parties; but a majority may appoint a time and place for the trial, decide any question which arises upon the trial, sign a report or settle a case. Any of them may administer an oath to a witness; and a majority of those present at a time and place appointed for the trial may adjourn the trial to a future day.
