Per Curiam.
Following his success in this Court in Perkins v. Standard Oil Co., 395 U. S. 642, the petitioner filed in the District Court for the District of Oregon an application for allowance of attorneys’ fees, pursuant to § 4 of the Clayton Act, for legal services performed during the appellate stages of that litigation, both in the Court of Appeals and in this Court. The District Court denied the application, ruling that § 4 did not authorize the allowance of attorneys’ fees for services performed in connection with appellate proceedings.
Petitioner appealed this decision to the Court of Appeals and simultaneously filed in that court two separate applications for attorneys’ fees for legal services performed there and in this Court. The Court of Appeals denied the latter application, believing that our mandate in Perkins, by not mentioning attorneys’ fees, was intended to preclude an award of such fees.
The District Court was in error in holding that § 4 does not authorize the award of counsel fees for legal services performed at the appellate stages of a successfully prosecuted private antitrust action. Both the language and purpose of § 4 make that construction untenable. See American Can Co. v. Ladoga Canning Co., 44 F. 2d 763, cert. denied, 282 U. S. 899. The amount of the award for such services should, as a general rule, be fixed in the first instance by the District Court, after hearing evidence as to the extent and nature of the services rendered. See, e. g., Osborn v. Sinclair Refining Co., 207 F. Supp. 856, 864. The Court of Appeals was also in error in interpreting our mandate as precluding the award of such fees for services performed in connection with the litigation in this Court. Our failure to make explicit mention in the mandate of attorneys’ fees simply left the matter open for consideration by the District Court, to which the mandate was directed.
The petitions for certiorari are granted and the judgments are vacated. No. 1556 is remanded to the District Court, and No. 1507 to the Court of Appeals, for further proceedings consistent with this opinion.
It is so ordered.
Mr. Justice Harlan took no part in the consideration or decision of these cases.
That section provides in pertinent part as follows:
“Any person who shall be injured in his business or property by reason of anything forbidden in the antitrust laws may sue therefor in any district court of the United States . . . and shall recover threefold the damages by him sustained, and the cost of suit, including a reasonable attorney’s fee.” 38 Stat. 731, 15 U. S. C. § 15.
What follows is an opinion from the Supreme Court of the United States. Your task is to determine whether the decision of the court whose decision the Supreme Court reviewed was itself liberal or conservative. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. The lower court's decision direction is unspecifiable if the manner in which the Supreme Court took jurisdiction is original or certification; or if the direction of the Supreme Court's decision is unspecifiable and the main issue pertains to private law or interstate relations
