Section 4
SEC. 4. The first paragraph of section thirty-five of Commonwealth Act Numbered Eighty-three is hereby amended to read as follows: "SEC. 35. Court review of orders.- (a) Any person aggrieved by an order issued by the Commission in a proceeding under this Act to which such person is a party or who may be affected thereby may obtain a review of such order in the Supreme Court of the Philippines by filing in such court within thirty days after the entry of such order a written petition praying that the order of the Commission be modified or set aside in whole or in part. A copy of such petition shall be forthwith served upon the Commission, and thereupon the Commission shall certify and file in the court a transcript of the record upon which the order complained of was entered. Upon the filing of such transcript, such court shall have exclusive jurisdiction to affirm, modify, and enforce or set aside such order, in whole or in part. No objection to the order of the Commission shall be considered unless such objection shall have been urged before the Commission, provided that opportunity therefor has been afforded. If either party shall apply to the court for leave to adduce additional evidence and shall show to the satisfaction of the court that such additional evidence is material and that there were reasonable grounds for failure to adduce such evidence in the hearing before the Commission, the court may order such additional evidence to be taken before the Commission and to be adduced upon the hearing in such manner and upon such terms and conditions as the court may deem proper. The Commission may modify its findings as to the facts, by reason of the additional evidence so taken, and it shall file such modified or new findings, and its recommendation, if any, for the modification or setting aside of the original order."
