Any person who is a party to a proceeding under this chapter aggrieved by any final order issued by the Commission in such proceeding may obtain review of such order in the United States Court of Appeals for any circuit in which the party to which such order relates is located or has its principal place of business, or in the United States Court of Appeals for the District of Columbia circuit. Review shall be obtained by filing a written petition, requesting that such order be modified or set aside in whole or in part, in such Court of Appeals within 60 days after the final action of the Commission on the application for rehearing required under paragraph (2). A copy of such petition shall forthwith be transmitted by the clerk of such court to any member of the Commission and thereupon the Commission shall file with the court the record upon which the order complained of was entered, as provided in section
2112 of title
28. Upon the filing of such petition such court shall have jurisdiction, which upon the filing of the record with it shall be exclusive, to affirm, modify, or set aside such order in whole or in part. No objection to such order of the Commission shall be considered by the court if such objection was not urged before the Commission in the application for rehearing unless there was reasonable ground for the failure to do so. The finding of the Commission as to the facts, if supported by substantial evidence, shall be conclusive. If any 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 proceedings 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 deems proper. The Commission may modify its findings as to the facts by reason of the additional evidence so taken, and shall file with the court such modified or new findings, which if supported by substantial evidence, shall be conclusive. The Commission shall also file with the court its recommendation, if any, for the modification or setting aside of the original order. The judgment and decree of the court, affirming, modifying, or setting aside, in whole or in part, any such order of the Commission, shall be final subject to review by the Supreme Court of the United States upon certiorari or certification as provided in section
1254 of title
28.
