If any such application is denied, the contractor may obtain a review of the order of denial in the United States Court of Appeals for the District of Columbia, by filing in such court, within twenty days after the entry of such order, a written petition praying that the order of the Secretary of Transportation be set aside. A copy of such petition shall be forthwith transmitted by the clerk of the court to the Secretary of Transportation or any officer designated by him for that purpose, and thereupon the Secretary of Transportation shall file in the court the record upon which the order complained of was entered, as provided in section
. Upon the filing of such petition such court shall have exclusive jurisdiction to determine whether such cancelation or default was without just cause, and to affirm or set aside such order. The judgment and decree of the court affirming or setting aside any such order of the Secretary of Transportation shall be final.
