(1) If, on the date fixed for hearing or any other date to which such hearing may be adjourned, if any party or his authorized agent or representative does not appear when the matter is called for hearing, the Commission may, in its discretion, either dismiss the petition for default when the petitioner or the person who moves the Commission for hearing is absent or proceed exparte to hear and decide the petition if the other party is absent.
(2) Where a petition is dismissed in default or decided exparte, the person aggrieved may file an application within 30 days from the date of such dismissal or being proceeded exparte, as the case may be, for recall of the order passed, and the Commission may recall the order on such terms as it thinks fit, if the Commission is satisfied that there was sufficient cause for the non-appearance of the person when the petition was called for hearing.
