Except as otherwise expressly provided by this section, in every civil action brought in any district court of the United States under the Act entitled "An Act to protect trade and commerce against unlawful restraints and monopolies", approved July 2, 1890, or any other Acts having like purpose that have been or hereafter may be enacted, in which the United States is the complainant and equitable relief is sought, any appeal from a final judgement entered in any such action shall be taken to the court of appeals pursuant to sections 1291 and 2107 of title 28. Any appeal from an interlocutory order entered in any such action shall be taken to the court of appeals pursuant to sections 1292(a)(1) and 2107 of title 28 but not otherwise. Any judgment entered by the court of appeals in any such action shall be subject to review by the Supreme Court upon a writ of certiorari as provided in section 1254(1) of title 28.
An appeal from a final judgment pursuant to subsection (a) of this section shall lie directly to the Supreme Court, if, upon application of a party filed within fifteen days of the filing of a notice of appeal, the district judge who adjudicated the case enters an order stating that immediate consideration of the appeal by the Supreme Court is of general public importance in the administration of justice. Such order shall be filed within thirty days after the filing of a notice of appeal. When such an order is filed, the appeal and any cross appeal shall be docketed in the time and manner prescribed by the rules of the Supreme Court. The Supreme Court shall thereupon either (1) dispose of the appeal and any cross appeal in the same manner as any other direct appeal authorized by law, or (2) in its discretion, deny the direct appeal and remand the case to the court of appeals, which shall then have jurisdiction to hear and determine the same as if the appeal and any cross appeal therein had been docketed in the court of appeals in the first instance pursuant to subsection (a) of this section.
