delivered the opinion of the Court.
Two tapes recording conversations between officials of the Church of Scientology (Church) and their attorneys in July 1980 have been the principal bone of contention in this, and two earlier, legal proceedings.
In an action filed in the Los Angeles County Superior Court, 1 the Church contended that the defendant had unlawfully acquired possession of the tapes. Pending resolution of that action, the state court ordered its Clerk to take custody of the tapes and certain other documents.
In 1984, in connection with an investigation of the tax returns of L. Ron Hubbard, founder of the Church of Scientology, the Internal Revenue Service (IRS) sought access to the Church documents in the state-court Clerk’s possession.

On January 18, 1985, the IRS commenced this proceeding by filing a petition to enforce the summons that had previously been served on the state-court Clerk.

The Church intervened and opposed production of the tapes on the ground that they were protected by the attorney-client privilege. After protracted proceedings, including review in this Court, see
United States
v.
Zolin,
“Because it is undisputed that the tapes have been turned over to the IRS in compliance with the summons enforcement order, no controversy exists presently and this appeal is moot.” United States v. Zolin, No. 91-55506 (CA9, Sept. 10, 1991).
We granted the Church’s petition for certiorari to consider the narrow question whether the appeal was properly dismissed as moot.

It has long been settled that a federal court has no authority “to give opinions upon moot questions or abstract propositions, or to declare principles or rules of law which cannot affect the matter in issue in the case before it.”

While a court may not be able to return the parties to the

form of meaningful relief in circumstances such as
We think the Government misconceives the inquiry in this case. The Government may or may not be right that under §§ 7402(b) and 7604(a) the jurisdiction of the
district court
is limited to those matters directly related to whether or not the summons should be enforced. Indeed, the scope of the district court’s jurisdiction under those provisions was the issue over which this Court deadlocked in

I — Í
We recognize that several Courts of Appeals have accepted the Government’s argument in IRS enforcement proceedings,

but the force of that line of authority is matched
We therefore conclude that the appeal was improperly dismissed as moot. In so concluding we express no opinion on the merits of the Church’s argument that the Government did not establish an adequate evidentiary basis to support the District Court’s determination that the tapes fell within the crime-fraud exception to the attorney-client privilege. Nor do we express any opinion about the res judicata contention advanced in the Government’s brief in opposition to the petition for certiorari. Brief for United States in Opposition
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.
Notes
Church of Scientology of California v. Armstrong, No. C420 153.
The Commissioner of Internal Revenue, as the delegate of the Secretary of the Treasury, has broad authority to examine the accuracy of federal tax returns. See generally
Donaldson
v.
United States,
“For the purpose of ascertaining the correctness of any return, making a return where none has been made, determining the liability of any person for any internal revenue tax or the liability at law or in equity of any transferee or fiduciary of any person in respect of any internal revenue tax, or collecting any such liability, the Secretary is authorized—
“(1) To examine any books, papers, records, or other data which may be relevant or material to such inquiry.” 26 U. S. C. § 7602(a).
Church of Scientology v. Armstrong, No. CV 84-9003-HLH (CD Cal., Nov. 27, 1984).
Sections 7402(b) and 7604(a) confer jurisdiction on the federal district courts to enforce a summons issued by the IRS. Title 26 U. S. C. § 7402(b) provides:
“If any person is summoned under the internal revenue laws to appear, to testify, or to produce books, papers, or other data, the district court of the United States for the district in which such person resides or may be found shall have jurisdiction by appropriate process to compel such attendance, testimony, or production of books, papers, or other data.”
Section 7604(a) is virtually identical to § 7402(b) except that the word “records” appears in § 7604(a).
The Fourth Amendment provides:
“The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.”
Petitioner also argues that a court can effectuate further relief by ordering the IRS to refrain from any future use of the information that it has derived from the tapes. Such an order would obviously go further towards returning the parties to the
status quo ante
than merely requiring the IRS to return the tapes and all copies thereof. However, as there is no guarantee that the IRS will in fact use the information gleaned from the tapes, it could be argued that such an order would be an impermissible advisory opinion. Cf.

FTC
v.
Gibson Products of San Antonio, Inc.,
There is no merit to the Government’s contention that the FTC cases are distinguishable in that they involve adjudicative, as opposed to investigative, subpoenas. While Gibson Products involved an adjudicative subpoena, Invention Submission, Casey, and Atlantic Richfield all involved investigative subpoenas.
In fact, the summons enforcement provisions of the Internal Revenue Code “closely paralle[lj” the corresponding provisions of the Federal Trade Commission Act. See Handler, Recent Antitrust Developments—
“Any of the district courts of the United States . . . may, in case of contumacy or refusal to obey a subpoena issued to any person, partnership, or corporation issue an order requiring such person, partnership, or corporation ... to produce documentary evidence if so ordered ....” 38 Stat. 722, as amended, 15 U. S. C. §49.
In the words of Professor Handler:
“Section 7602 of the Internal Revenue Code authorizes the Secretary of the Treasury or his delegate to summon taxpayers or other witnesses to testify and to produce relevant and material documents. Section 9 of the FTC Act grants the same power to the Commission. Should a recipient of a summons or subpoena refuse to comply, both statutes afford the same enforcement procedures. In neither case is the administrative subpoena self-executing: obedience can be obtained only by court order. In addition, both statutes, which are in pari materia, make it a criminal offense to ‘neglect’ to appear or to produce subpoenaed documents.”63 Mich. L. Rev., at 91 (footnotes omitted).
In reaching this conclusion, we reject petitioner’s “fall back” argument that even if compliance with a summons enforcement order by the subject of the IRS investigation moots an appeal, compliance by a disinterested third party — here, the Clerk of the Los Angeles Superior Court — does not. Brief for Petitioner 25-34; Reply Brief for Petitioner 16-18. We agree with the Government that a “difference in the method of compliance does not create a distinction for the purpose of the constitutional case or controversy requirement.” Brief for United States 30. This case presents a justiciable controversy not because a third party complied with the summons enforcement order, but because petitioner has a stake in the outcome of the proceeding and a federal court can effectuate relief should petitioner prevail on the merits.
There is a distinction in the law between the enforcement of discovery orders directed at parties and the enforcement of discovery orders directed at disinterested third parties, but that distinction derives from concerns regarding finality, not mootness. As a general rule, a district court’s order enforcing a discovery request is riot a “final order” subject to appellate review. A party that seeks to present an objection to a discovery order immediately to a court of appeals must refuse compliance, be held in contempt, and then appeal the contempt order. See
