(1) Any person aggrieved by the refusal of the Registrar to grant registration to a Trade Union under section 9 or by cancellation of a certificate of registration under sub-section (5) of the said section, may within such period as may be prescribed, prefer an appeal to the Tribunal:
Provided that the Tribunal may entertain the appeal after the limitation prescribed for preferring the appeal under this sub-section, if the appellant satisfies the Tribunal that such delay has been caused due to sufficient reason or unavoidable circumstances.
(2) The Tribunal may, after giving the parties concerned an opportunity of being heard, dismiss the appeal or pass an order directing the Registrar to register the Trade Union and to issue a certificate of registration or set aside the order of cancellation of certificate of registration, as the case may be and forward a copy of such order to the Registrar.
