Per Curiam.
Terry Whitman, the petitioner, is an employee of the Federal Aviation Administration (FAA) and is subject to the agency’s drug and alcohol testing program. Without first seeking to pursue grievance procedures under his collective-bargaining agreement, he filed suit in the United States District Court for the District of Alaska, alleging the FAA tested him in a nonrandom manner, in violation of his constitutional rights and 49 U. S. C. § 45104(8).
The FAA has its own procedural framework for the resolution of claims by its employees; and for this purpose it adopts certain sections of the Civil Service Reform Act of 1978 (CSRA), including Chapter 71 of Title 5, which sets forth the rules for grievances. 49 U. S. C. § 40122(g)(2)(C). The District Court held that, under the provisions of the CSRA, it was without jurisdiction to consider the petitioner’s claims. The Court of Appeals for the Ninth Circuit affirmed, stating that because “5 U. S. C. § 7121(a)(1), as amended in 1994, does not expressly confer federal court jurisdiction over employment-related claims covered by the negotiated grievance procedures of federal employees’ collective bargaining agreements,” his claims are precluded. 382 F. 3d 938, 939 (2004). This Court granted certiorari to review the judgment. 545 U. S. 1138 (2005).
The Court of Appeals was correct to say that 5 U. S. C. § 7121(a)(1) does not confer jurisdiction. Another statute, however — a very familiar one — grants jurisdiction to the federal courts over “all civil actions arising under the Constitution, laws, or treaties of the United States.” 28 U. S. C. § 1331. The question, then, is not whether 5 U. S. C. § 7121 confers jurisdiction, but whether § 7121 (or the CSRA as a whole) removes the jurisdiction given to the federal courts, see Verizon Md. Inc. v. Public Serv. Comm’n of Md., 535 U. S. 635, 642 (2002) (holding that “even if [47 U. S. CJ § 252(e)(6) does not confer jurisdiction, it at least does not divest the district courts of their authority under 28 U. S. C. § 1331 to review the Commission’s order for compliance with federal law”), or otherwise precludes employees from pursuing remedies beyond those set out in the CSRA, cf. United States v. Fausto, 484 U. S. 439, 443-444 (1988); Abbott Laboratories v. Gardner, 387 U. S. 136, 140 (1967) (“The question is phrased in terms of ‘prohibition’ rather than ‘authorization’ because . . . judicial review of a final agency action by an aggrieved person will not be cut off unless there is persuasive reason to believe that such was the purpose of Congress”).
In deciding the question of jurisdiction and preclusion, the Court would be required first to ascertain where Whitman’s claims fit within the statutory scheme, as the CSRA provides different treatment for grievances depending on the nature of the claim. It may be, for example, that the FAA’s actions, as described by the petitioner, constitute a “prohibited personnel practice.” See 5 U. S. C. § 2302(b); 49 U. S. C. § 40122(g)(2)(A). Both the petitioner and the Government say they do not, but because the ultimate question may be jurisdictional, this concession ought not to be accepted out of hand. See Weinberger v. Bentex Pharmaceuticals, Inc., 412 U. S. 645, 652 (1973) (“Parties, of course, cannot confer jurisdiction; only Congress can do so”). The Court of Appeals did not decide whether the petitioner’s allegations state a “prohibited personnel practice.” The proper course, then, is to remand for the Court of Appeals to address the matter, see National Collegiate Athletic Assn. v. Smith, 525 U. S. 459, 470 (1999), as well as the ultimate issue of preclusion. The various other issues raised before this Court, but not decided below, may also be addressed on remand, including: whether the petitioner has challenged final agency action; whether the petitioner has exhausted his administrative remedies; whether exhaustion is required given this statutory scheme and the Administrative Procedure Act, as interpreted in Darby v. Cisneros, 509 U. S. 137 (1993); and whether the Government has forfeited its exhaustion-of-remedies argument. It may be that a decision on these questions can obviate the need to decide a more difficult question of preclusion.
The judgment of the Court of Appeals is vacated, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.

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
