The Authority may petition any appropriate United States court of appeals for the enforcement of any order of the Authority and for appropriate temporary relief or restraining order.

Upon the filing of a petition under subsection (a) of this section for judicial review or under subsection (b) of this section for enforcement, the Authority shall file in the court the record in the proceedings, as provided in section 2112 of title 28. Upon the filing of the petition, the court shall cause notice thereof to be served to the parties involved, and thereupon shall have jurisdiction of the proceeding and of the question determined therein and may grant any temporary relief (including a temporary restraining order) it considers just and proper, and may make and enter a decree affirming and enforcing, modifying and enforcing as so modified, or setting aside in whole or in part the order of the Authority. The filing of a petition under subsection (a) or (b) of this section shall not operate as a stay of the Authority’s order unless the court specifically orders the stay. Review of the Authority’s order shall be on the record in accordance with section 706 of this title. No objection that has not been urged before the Authority, or its designee, shall be considered by the court, unless the failure or neglect to urge the objection is excused because of extraordinary circumstances. The findings of the Authority with respect to questions of fact, if supported by substantial evidence on the record considered as a whole, shall be conclusive. If any person applies to the court for leave to adduce additional evidence and shows to the satisfaction of the court that the additional evidence is material and that there were reasonable grounds for the failure to adduce the evidence in the hearing before the Authority, or its designee, the court may order the additional evidence to be taken before the Authority, or its designee, and to be made a part of the record. The Authority may modify its findings as to the facts, or make new findings by reason of additional evidence so taken and filed. The Authority shall file its modified or new findings, which, with respect to questions of fact, if supported by substantial evidence on the record considered as a whole, shall be conclusive. The Authority shall file its recommendations, if any, for the modification or setting aside of its original order. Upon the filing of the record with the court, the jurisdiction of the court shall be exclusive and its judgment and decree shall be final, except that the judgment and decree shall be subject to review by the Supreme Court of the United States upon writ of certiorari or certification as provided in section 1254 of title 28.

The Authority may, upon issuance of a complaint as provided in section 7118 of this title charging that any person has engaged in or is engaging in an unfair labor practice, petition any United States district court within any district in which the unfair labor practice in question is alleged to have occurred or in which such person resides or transacts business for appropriate temporary relief (including a restraining order). Upon the filing of the petition, the court shall cause notice thereof to be served upon the person, and thereupon shall have jurisdiction to grant any temporary relief (including a temporary restraining order) it considers just and proper. A court shall not grant any temporary relief under this section if it would interfere with the ability of the agency to carry out its essential functions or if the Authority fails to establish probable cause that an unfair labor practice is being committed.
