An order made under section 193 of this title shall be final and conclusive unless within thirty days after service the packer or swine contractor appeals to the court of appeals for the circuit in which he has his principal place of business, by filing with the clerk of such court a written petition praying that the Secretary’s order be set aside or modified in the manner stated in the petition, together with a bond in such sum as the court may determine, conditioned that such packer or swine contractor will pay the costs of the proceedings if the court so directs.
The clerk of the court shall immediately cause a copy of the petition to be delivered to the Secretary, and the Secretary shall thereupon file in the court the record in such proceedings, as provided in section 2112 of title 28. If before such record is filed the Secretary amends or sets aside his report or order, in whole or in part, the petitioner may amend the petition within such time as the court may determine, on notice to the Secretary.
At any time after such petition is filed, the court, on application of the Secretary, may issue a temporary injunction, restraining, to the extent it deems proper, the packer or swine contractor and his officers, directors, agents, and employees, from violating any of the provisions of the order pending the final determination of the appeal.
The evidence so taken or admitted, and filed as aforesaid as a part of the record, shall be considered by the court as the evidence in the case.
If the court determines that the just and proper disposition of the case requires the taking of additional evidence, the court shall order the hearing to be reopened for the taking of such evidence, in such manner and upon such terms and conditions as the court may deem proper. The Secretary may modify his findings as to the facts, or make new findings, by reason of the additional evidence so taken, and he shall file such modified or new findings and his recommendations, if any, for the modifications or setting aside of his order, with the return of such additional evidence.
The court of appeals shall have jurisdiction, which upon the filing of the record with it shall be exclusive, to review, and to affirm, set aside, or modify, such orders of the Secretary, and the decree of such court shall be final except that it shall be subject to review by the Supreme Court of the United States upon certiorari, as provided in section 1254 of title 28, if such writ is duly applied for within sixty days after entry of the decree. The issue of such writ shall not operate as a stay of the decree of the court of appeals, insofar as such decree operates as an injunction unless so ordered by the Supreme Court.
