49.—(1) Upon completion of the evidence, the Registrar shall give notice to the parties of a date when he will hear the arguments in the case.
(2) Any party who intends to appear shall so notify the Registrar on Form T.M. 13 before the hearing.
(3) Any party who does not so notify the Registrar on Form T.M. 13 before the hearing may be treated as not desiring to be heard, and the Registrar may proceed with the hearing in the absence of that party, or may without proceeding with the hearing give his decision or dismiss the proceedings, or make any other order as he thinks fit.
(4) If subsequent to notifying the Registrar on Form T.M. 13 a party does not appear at the hearing, the Registrar may proceed with the hearing in the absence of that party, or may without proceeding with the hearing give his decision or dismiss the proceedings, or make any other order as he thinks fit.
(5) If, at the hearing, neither party appears, the proceedings may be struck out of the list without prejudice, however, to the restoration thereof, on the direction of the Registrar.
(6) Any decision obtained where any party does not appear at the hearing may be set aside by the Registrar on the application of that party on such terms as he thinks fit.
(7) An application under this rule for the restoration of any proceedings or the setting aside of any decision made pursuant to paragraph (S) or (6) shall be made within 7 days after the proceedings have been struck out of the list or after the hearing, as the case may be.
