Unless the arbitration agreement otherwise provides—
| (a) | the umpire may sit together with the arbitrators and hear the evidence given from time to time and may then and there decide any matter of procedure or any interlocutory question upon which the arbitrators disagree and which is referred by them to him for decision; |
| (b) | an umpire shall not be entitled to any remuneration from the parties in respect of his attendance at any arbitration proceedings conducted by the arbitrators unless the parties have requested him so to attend or unless he is called upon to decide any matter of procedure or any interlocutory question at the request of the arbitrators or is required to enter on the reference and to give an award; |
| (c) | if the arbitrators have by notice in writing advised the parties to the reference, or the umpire, that they are unable to agree, or if the arbitrators have allowed the time or extended time for making their award to expire without making an award, and the parties have not advised the umpire that they intend to grant an extension or further extension of the said period or to apply to the court therefor, the umpire shall forthwith enter on the reference in lieu of the arbitrators; |
| (d) | an umpire who enters on a reference as provided in paragraph (c), shall have the same powers as if he had been appointed as sole arbitrator, and may for that purpose unless he is required by the parties to hear the evidence of the parties and their witnesses, or, whenever he is called upon by the arbitrators to decide any matter of procedure or any interlocutory question, act upon the evidence recorded in the proceedings before the arbitrators, and may, if he thinks fit, recall for further examination any person who has given such evidence. |
