51. Termination of proceedings
(1) The arbitral proceedings are terminated by the arbitral tribunal's award, or where more than one award is made by the arbitral tribunal's final or last award, or by an order of the arbitral tribunal in accordance with subsection (2).
(2) The arbitral tribunal shall issue an order for the termination of the arbitral proceedings when:
(a) the claimant withdraws his claim, unless the respondent objects thereto and the arbitral tribunal recognises a legitimate interest on his part in obtaining a final settlement of the dispute;
(b) the parties agree on the termination of the proceedings; or
(c) at the request of a party, the arbitral tribunal finds that the continuation of the proceedings has for any other reason become unnecessary or impossible.
If the arbitral tribunal issues an order for termination under this subsection (2), unless otherwise agreed by the parties, the arbitral tribunal may issue an award on costs in accordance with section 50 above.
(3) The mandate of the arbitral tribunal terminates with the termination of the arbitral proceedings, subject to the provisions of subsection (5) and of sections 52 and 53.
(4) The arbitral tribunal may refuse to deliver a final award or an order for termination of the arbitral proceedings in accordance with subsection (2) until its fees and expenses are paid in full.
(5) Subject to any process agreed between the parties in the arbitration agreement, if the arbitral tribunal refuses to deliver an award or order until its fees and expenses are paid, any party to the arbitral proceedings may request the arbitral institution administering the arbitration, or, where there is no such institution, the Court to determine, by such means as it considers appropriate, the amount of the fees and expenses properly payable to the arbitral tribunal.
