(a) Finality of order unless appeal to court of appeals; time limit; bond
An order made under section 228b–2 of this title shall be final and conclusive unless within 30 days after service the live poultry dealer 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 live poultry dealer will pay the costs of the proceedings if the court so directs.

(b) Notification of appeal to Secretary; filing of record with court
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.

(c) Issuance of temporary injunction
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 live poultry dealer and his officers, directors, agents, and employees, from violating any of the provisions of the order pending the final determination of the appeal.

(d) Evidence in record as evidence in case; expedited proceedings
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. The proceedings in such cases in the court of appeals shall be made a preferred cause and shall be expedited in every way.

(e) Action by court
The court may affirm, modify, or set aside the order of the Secretary.

(f) Taking of additional evidence; modified or additional findings by Secretary
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 modification or setting aside of his order, with the return of such additional evidence.

(g) Affirmance or modification of order as injunction
If the court of appeals affirms or modifies the order of the Secretary, its decree shall operate as an injunction to restrain the live poultry dealer, and his officers, directors, agents, and employees from violating the provisions of such order or such order as modified.

(h) Exclusive jurisdiction of court of appeals; finality of decree; appeal to Supreme Court; stay of decree
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 60 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.
