(1) An appeal shall lie to the Supreme Court—

(a) from any order passed by the National Bench or Regional Benches of the Appellate Tribunal; or
(b) from any judgment or order passed by the High Court in an appeal made under section 117 in any case which, on its own motion or on an application made by or on behalf of the party aggrieved, immediately after passing of the judgment or order, the High Court certifies to be a fit one for appeal to the Supreme Court.

(2) The provisions of the Code of Civil Procedure, 1908, relating to appeals to the Supreme Court shall, so far as may be, apply in the case of appeals under this section as they apply in the case of appeals from decrees of a High Court.
