Justice Blackmun
delivered the opinion of the Court.
The United States seeks reinstatement of a judgment of contempt against a newspaper and its executive editor for violating an invalid temporary restraining order against publication. Having concluded that the court-appointed prosecutor who sought certiorari and briefed and argued the case without the authorization of the Solicitor General may not represent the United States before this Court, we dismiss the writ of certiorari.
I
On November 8, 1985, Raymond J. Patriarca, son of Raymond L. S. Patriarca, by then deceased, filed suit against the Federal Bureau of Investigation (FBI), its Director, the Department of Justice, the Attorney General of the United States, the Providence Journal Company (Journal), and WJAR Television Ten (WJAR), seeking to enjoin further dissemination of logs and memoranda compiled from 1962 to 1965 during the course of illegal electronic surveillance, see Providence Journal Co. v. FBI, 602 F. 2d 1010, 1013 (CA1 1979), cert. denied, 444 U. S. 1071 (1980), of the plaintiff’s father. The complaint, as amended, was based on the Freedom of Information Act (FOIA), 5 U. S. C. § 552 (1982 ed., and Supp. IV), Title III of the Omnibus Crime Control and Safe Streets Act of 1968 (Title III), 18 U. S. C. § 2510 et seq. (1982 ed., and Supp. IV), and the Fourth Amendment, and alleged that the FBI had improperly released the logs and memoranda to the journal and WJAR pursuant to a FOIA request following the death of the senior Patriarca. The summons, complaint, and a motion for a temporary restraining order were served on the Journal on November 12, 1985. The next day counsel for the various parties gathered for a conference with the Chief Judge of the United States District Court for the District of Rhode Island. During that conference, of which, apparently, there is no transcript, the Chief Judge entered a temporary restraining order barring publication of the logs and memoranda and set a hearing for Friday, November 15. Counsel for both the Journal and the federal defendants objected to the order.
During the evening of November 13, respondent Charles M. Hauser, executive editor of the Journal, was first advised of the restraining order. After discussing with other Journal executives the perils of noncompliance, Hauser decided to publish a story based on the logs and memoranda. The following day, November 14, the Journal published one article about the Patriarcas and another about the “clash” between the District Court and the Journal. See App. 39, 18. Patriarca forthwith filed a motion to have the Journal and Hauser adjudged in criminal contempt. Id., at 223.
Patriarca, however, declined to prosecute the contempt motion, and the District Court decided not to ask the United States Attorney to pursue the matter because of his representation of the federal defendants in the underlying civil action. Invoking Federal Rule of Criminal Procedure 42(b), the District Court appointed William A. Curran of the Rhode Island Bar as “prosecuting attorney with full authority to prosecute” the pending contempt motion. App. 237-238. On Curran’s application, the District Court then ordered respondents to show cause why they should not be adjudged in criminal contempt. Id., at 31-32.
Following a hearing on February 10, 1986, the District Court found respondents in criminal contempt of the order entered on November 13. The court concluded that it had jurisdiction to consider whether Patriarca’s statutory and Fourth Amendment claims had merit, and whether his privacy interest outweighed the Journal’s First Amendment interest in publication, and thus that the temporary restraining order entered to preserve the status quo pending consideration of significant legal issues was valid, even though it subsequently had been vacated. The District Court fined the Journal $100,000 and suspended a jail sentence for Hauser, placing him on probation for 18 months and ordering that he perform 200 hours of public service. Id., at 194-197.
Respondents appealed, and the United States Court of Appeals for the First Circuit reversed the judgment of contempt. In re Providence Journal Co., 820 F. 2d 1342 (1986). The court found that the temporary restraining order was “transparently invalid” under the First Amendment, and thus its constitutionality could be collaterally challenged in the contempt proceedings. Id., at 1353. According to the court, none of the grounds asserted in support of the order, including FOIA, Title III, and the Fourth Amendment, provided even a colorable basis for the prior restraint ordered by the District Court.
The Court of Appeals, then sitting en banc, summarily modified the panel’s opinion, holding that even those subject to a transparently invalid order must make a good-faith effort to seek emergency appellate relief. It ruled, however, that the publisher may proceed to publish and challenge the constitutionality of the order in the contempt proceeding if timely access to the appellate court is not available or if a timely decision is not forthcoming. The court was not convinced that respondents could have obtained emergency relief before the publisher had to make a final decision whether to run the story the following day, and found it unfair to subject respondents to substantial sanctions for failing to follow the newly announced procedures. In re Providence Journal Co., 820 F. 2d 1354 (1987).
Because of the importance of the issues, we granted certiorari. 484 U. S. 814 (1987).
II
Before we can decide whether respondents could properly be held in contempt for violating the District Court’s subsequently invalidated restraining order, we must consider respondents’ motion to dismiss the writ of certiorari. It appears that the manner in which this unusual case reached us departed significantly from established practice. After the Court of Appeals reversed the judgment of contempt and, sitting en banc, modified the panel’s opinion, the special prosecutor sought authorization from the Solicitor General to file a petition here for a writ of certiorari. By letter dated July 2, 1987, the Solicitor General denied that authorization. See App. to Brief for United States as Amicus Curiae in Response to Respondents’ Motion to Dismiss la-2a (SG Letter). Respondents argue that, without this permission, the special prosecutor cannot proceed before this Court. While denying authorization to the special prosecutor to file or to appear on behalf of the United States, the Solicitor General questioned whether our recent decision in Young v. United States ex rel. Vuitton et Fils S. A., 481 U. S. 787 (1987), rendered such authorization unnecessary in a case concerning a criminal contempt charge prosecuted by private counsel appointed pursuant to Federal Rule of Criminal Procedure 42(b). See SG Letter. See also Brief for United States as Amicus Curiae 2, n. 2. We find no such implication in our decision in Young, and we conclude that the special prosecutor lacks the authority to represent the United States before this Court. Because he is not a party entitled to petition for certiorari under 28 U. S. C. § 1254(1), we must dismiss the heretofore-granted writ of certiorari for want of jurisdiction.
A
Title 28 U. S. C. § 518(a) provides in relevant part:
“Except when the Attorney General in a particular case directs otherwise, the Attorney General and the Solicitor General shall conduct and argue suits and appeals in the Supreme Court... in which the United States is interested.”
The Attorney General by regulation has delegated authority to the Solicitor General:
“The following-described matters are assigned to, and shall be conducted, handled, or supervised by, the Solicitor General, in consultation with each agency or official concerned:
“(a) Conducting, or assigning and supervising, all Supreme Court cases, including appeals, petitions for and in opposition to certiorari, briefs and arguments, and . . . settlement thereof.” 28 CFR § 0.20 (1987).
Thus, unless this is a case other than one “in which the United States is interested,” § 518(a), it must be conducted and argued in this Court by the Solicitor General or his designee. Cf. United States v. Winston, 170 U. S. 522, 524-525 (1898); Confiscation Cases, 7 Wall. 454, 458 (1869).
B
The present case clearly is one “in which the United States is interested.” The action was initiated in vindication of the “judicial Power of the United States,” U. S. Const., Art. III, § 1 (emphasis added), and it is that interest, unique to the sovereign, that continues now to be litigated in this Court. The special prosecutor seeks to reinstate a judgment of criminal contempt in a federal court, including a possible prison sentence for the individual defendant and a substantial fine for the newspaper defendant. The fact that the allegedly criminal conduct concerns the violation of a court order instead of common law or a statutory prohibition does not render the prosecution any less an exercise of the sovereign power of the United States. Indeed, just last Term, in a case much like the present one, involving a prosecution for criminal contempt under 18 U. S. C. § 401(3), we flatly stated: “Private attorneys appointed to prosecute a criminal contempt action represent the United States . . . Young v. United States ex rel. Vuitton et Fils S. A., 481 U. S., at 804 (emphasis added). See also Gompers v. Bucks Stove & Range Co., 221 U. S. 418, 445 (1911) (“[Proceedings at law for criminal contempt are between the public and the defendant. . .”).
The special prosecutor and the Solicitor General argue that this case is not one “in which the United States is interested” because that phrase, as used in § 518(a), refers solely to those cases where the interests of the Executive Branch of the United States are at issue. In this litigation, the argument goes, the special prosecutor acted in support of the power of the Judicial Branch, rather than in furtherance of the Executive’s constitutional responsibility, U. S. Const., Art. II, § 3, to “take Care that the Laws be faithfully executed.” This suggested interpretation of § 518(a), however, presumes that there is more than one “United States” that may appear before this Court, and that the United States is something other than “the sovereign composed of the three branches . . . .” United States v. Nixon, 418 U. S. 683, 696 (1974).
We find such a proposition somewhat startling, particularly when supported by the office whose authority would be substantially diminished by its adoption, and we reject that construction as inconsistent with the plain meaning of § 518(a). It seems to be elementary that even when exercising distinct and jealously separated powers, the three branches are but “co-ordinate parts of one government.” J. W. Hampton, Jr., & Co. v. United States, 276 U. S. 394, 406 (1928). Congress is familiar enough with the language of separation of powers that we shall not assume it intended, without saying so, to exclude the Judicial Branch when it referred to the “interest of the United States.” Moreover, while there may well be matters that are uniquely Executive Branch concerns, we do not think they would be fairly described by the broad statutory language of § 518(a).
In Young, we reaffirmed the inherent authority of a federal court to initiate a criminal contempt proceeding for disobedience of its order, and its ability to appoint a private attorney to prosecute the contempt action. 481 U. S., at 793. This power, considered to be a part of the judicial function, is grounded first and foremost upon necessity: “The ability to punish disobedience to judicial orders is regarded as essential to ensuring that the Judiciary has a means to vindicate its own authority without complete dependence on other branches.” Id., at 796. The special prosecutor claims his appearance before this Court is necessary for the vindication of the District Court’s authority. For just as the District Court would be “at the mercy of another branch in deciding whether such proceedings should be initiated,” ibid., if it lacked the power to appoint a private attorney to prosecute a contempt charge, the judgment vindicating the District Court’s authority would be vulnerable to the Attorney General’s withholding of authorization to defend it. This argument, however, overlooks the circumstances under which the special prosecutor actually came to be in a position to seek review in this Court.
When, as here, a district court’s judgment of contempt has been reversed on appeal, a special prosecutor may decide to seek a writ of certiorari on the basis of his professional judgment that the court of appeals’ decision merits review. See generally this Court’s Rule 17. Sometimes, as apparently occurred here, the special prosecutor and the Solicitor General will disagree with respect to whether the case presents issues worthy of review by this Court. That kind of disagreement actually arises on a regular basis between the Solicitor General and attorneys representing various agencies of the United States. But that disagreement does not interfere with the Judiciary’s power to protect itself. In this very case, before the consent of the Solicitor General ever became relevant, members of the Judiciary had decided that the District Judge erred in adjudging the defendants in contempt. Where the majority of a panel of a court of appeals or perhaps, as here, a majority of an en banc court, itself has decided in favor of the alleged contemner, the necessity that required the appointment of an independent prosecutor has faded and, indeed, is no longer present.
When, on the other hand, a district court has adjudged a party in contempt, and the appellate court has affirmed, a special prosecutor has little need of the services of this Court to fulfill his or her duties. It is only if the contemner petitions this Court for a writ of certiorari that the Solicitor General need be consulted and his authorization or participation obtained to oppose the petition and defend the judgment. Under such circumstances, if the Solicitor General declines to authorize a defense of the judgment and if § 518(a) prevented the special prosecutor from proceeding, the independent ability of the Judiciary to vindicate its authority might appear to be threatened: both courts would have agreed that the contemner had disobeyed an order of the court, but the Executive’s judgment to the contrary would threaten to undermine those judicial decisions. This threat, however, is inconsequential, for it is this Court, a part of the Judicial Branch, that must decide whether to exercise its discretion to review the judgment below, and it is well within this Court’s authority to appoint an amicus curiae to file briefs and present oral argument in support of that judgment. See, e. g., Bob Jones University v. United States, 456 U. S. 922 (1982) (order appointing amicus curiae in support of judgment); United States v. Fausto, 480 U. S. 904 (1987) (same).
The Solicitor General argues that § 518(a) does not apply to a contempt proceeding that is initiated unilaterally by a federal court, because in Young this Court sustained the power of the court to appoint a private attorney to prosecute a criminal contempt charge, despite the fact that 28 U. S. C. § 516, in language certainly somewhat similar to that of § 518(a), requires such litigation to be conducted by a Government attorney:
“Except as otherwise authorized by law, the conduct of litigation in which the United States, an agency, or officer thereof is a party, or is interested, ... is reserved to officers of the Department of Justice, under the direction of the Attorney General.”
Also, 28 U. S. C. § 547 requires: “Except as otherwise provided by law, each United States attorney, within his district, shall. . . prosecute for all offenses against the United States.” The Solicitor General concludes that Young necessarily implies that these broadly worded reservations of litigating authority, including § 518(a), do not apply to the case at hand.
Young neither expressed nor implied any such special consideration for a judicially initiated contempt proceeding. Both statutes implicated but not discussed in Young provide for the Attorney General’s exclusive control over specified litigation except as otherwise provided or authorized by law. A fair reading of Young indicates that a federal court’s inherent authority to punish disobedience and vindicate its authority is an excepted provision or authorization within the meaning of §§ 516 and 547. The “‘power to punish for contempts is inherent in all courts,’ ” and was not first recognized by this Court in Young; rather, it “‘has .been many times decided and may be regarded as settled law.”’ Young, 481 U. S., at 795, quoting Michaelson v. United States ex rel. Chicago, St. P., M. & O. R. Co., 266 U. S. 42, 65-66 (1924). Thus, contrary to the Solicitor General’s intimation, Young did not read an exception into §§ 516 and 547; instead, Young is consistent with the plain language of the provisos to those sections. Section 518(a), by way of vivid contrast, contains no such proviso.
c
If the plain statutory language of § 518(a) were not reason enough to persuade us to accept respondents’ objections and dismiss the writ of certiorari, we observe that the salutory policies that support § 518(a) could be undermined by, and anomalous consequences could result from, the approach urged upon the Court by the special prosecutor and the Solicitor General. Among the reasons for reserving litigation in this Court to the Attorney General and the Solicitor General, is the concern that the United States usually should speak with one voice before this Court, and with a voice that reflects not the parochial interests of a particular agency, but the common interests of the Government and therefore of all the people. Without the centralization of the decision whether to seek certiorari, this Court might well be deluged with petitions from every federal prosecutor, agency, or instrumentality, urging as the position of the United States, a variety of inconsistent positions shaped by the immediate demands of the case sub judice, rather than by longer term interests in the development of the law.
Under the procedures set out in Young, it seems evident that the majority of contempt cases will be prosecuted by the United States Attorney. See 481 U. S., at 801. Under the special prosecutor’s interpretation of § 518(a), whereby a contempt citation initiated by a district court is not a case “in which the United States is interested,” the United States Attorney would be free to file a petition for a writ of certiorari in this Court without the authorization of the Solicitor General. We need not speculate how a United States Attorney would resolve the conflict between his duty “to the preservation of respect for judicial authority,” United States Attorneys’ Manual §9-39.318 (1984), and his duty to his superiors at the Department of Justice, because we reject out of hand the interpretation of § 518(a) that creates the potential for such a conflict. Similarly, if the United States Attorney concluded that a court of appeals’ decision reversing a judgment of contempt did not merit further review and declined to file a petition with this Court, it would seem to follow from the Solicitor General’s interpretation, that the district judge could then appoint another special prosecutor solely for purposes of seeking certiorari and, if the writ were granted, litigating the case before this Court. See Brief for United States as Amicus Curiae in Response to Respondents’ Motion to Dismiss 9, n. 7. But, surely, neither the force of historical practice, nor the necessity of protecting the dignity of the district court— whose judgment of contempt has been reversed on appeal-warrants attributing such power to the district judge.
Ill
We conclude that a criminal contempt prosecution brought to vindicate the authority of the Judiciary and to punish disobedience of a court order is a suit “in which the United States is interested,” within the meaning of § 518(a), regardless of who is appointed by the district court to prosecute the action. In this case, the special prosecutor filed a petition for a writ of certiorari without the authorization of the Solicitor General, and thus without authorization to appear on behalf of the United States. Absent a proper representative of the Government as a petitioner in this criminal prosecution, jurisdiction is lacking and the writ of certiorari, heretofore granted, is now dismissed.
It is so ordered.
Justice Kennedy took no part in the consideration or decision of this case.
The conference was held in the Chief Judge’s chambers at 12:30 p.m. on November 13. The District Court was prepared to hear argument the very next day, but, in order to accommodate counsel, set the matter for November 15 at 10 a.m.
On November 15, as previously scheduled, the District Court held a hearing. After argument by counsel, the court set a preliminary injunction hearing for Tuesday, November 19, extending the restraining order until that date. App. 58-71. Following the preliminary injunction hearing, the court vacated the temporary restraining order, denied preliminary injunctive relief against the Journal and WJAR, and granted a preliminary injunction against further dissemination of the logs and memoranda by the federal defendants. Id., at 71-89.
Our decision in Young v. United States ex rel. Vuitton et Fils S. A., 481 U. S. 787 (1987), in any event, would have prohibited Patriarca from taking such action. In Young, we instructed courts to request the United States Attorney to prosecute the criminal contempt charge, and, if the United States Attorney declined, to appoint as a special prosecutor a private attorney other than the attorney for an interested party. Id., at 801.
The United States as amicus curiae, argues that the District Court’s reasons were legally “insufficient” to support the decision not to ask a Government attorney to undertake the contempt prosecution, because the proseeution of the Journal in order to vindicate the District Court’s authority did not pose any conflict for Government attorneys. Brief for United States as Amicus Curiae 1, and n. 1. Because of our disposition of this case, we need not address the circumstances under which the procedures prescribed in Young, of requesting the appropriate prosecuting authority to pursue the contempt action, may be bypassed.
As we hold today, a federal statute deprives the special prosecutor of the authority to pursue the litigation in this Court on behalf of the United States when the Solicitor General declines to petition for certiorari or to authorize the filing of such a petition. We dismiss the writ even though the United States eventually expressed its “interest” in the litigation and the Solicitor General filed a brief for the United States as amicus curiae in support of the position taken by the special prosecutor. See Karcher v. May, 484 U. S. 72 (1987); Diamond v. Charles, 476 U. S. 54, 63-64 (1986).
Section 401 reads: “A court of the United States shall have power to punish by fine or imprisonment, at its discretion, such contempt of its authority, and none other, as . . . (3) Disobedience or resistance to its lawful writ, process, order, rule, decree, or command.”
In fact, this Court relies on the Solicitor General to exercise such independent judgment and to decline to authorize petitions for review in this Court in the majority of the cases the Government has lost in the courts of appeals. See Andres v. United States, 333 U. S. 740, 764-765, n. 9 (1948) (Frankfurter, J., concurring); MeCree, The Solicitor General and His Client, 59 Wash. U. L. Q. 337, 341 (1981). See also Griswold, The Office of the Solicitor General — Representing the Interests of the United States Before the Supreme Court, 34 Mo. L. Rev. 527, 535 (1969) (“The Solicitor General has a special obligation to aid the Court as well as to serve his client. ... In providing for the Solicitor General, subject to the direction of the Attorney General, to attend to the ‘interests of the United States’ in litigation, the statutes have always been understood to mean the long-range interests of the United States, not simply in terms of its fisc, or its success in the particular litigation, but as a government, as a people”) (footnote omitted).
In Young we emphasized:
“This principle of restraint in contempt counsels caution in the exercise of the power to appoint a private prosecutor. We repeat that the rationale for the appointment authority is necessity. If the Judiciary were completely dependent on the Executive Branch to redress direct affronts to its authority, it would be powerless to protect itself if that branch declined prosecution. . . . [T]he court will exercise its inherent power of self-protection only as a last resort.” 481 U. S., at 801.
The plain language of §§ 516 and 547 resolves any conflict between the express reservations of authority over litigation therein provided and any other provision of law that vests litigation authority elsewhere. A statute that begins with “Except as otherwise provided by law” creates a general rule that applies unless contradicted in some other provision. The Court in Young had no reason to address the application of §§ 516 and 547. This was not because those provisions do not apply to a contempt proceeding initiated by a court, but because having reaffirmed the well-established inherent authority of a federal court to appoint a private attorney to prosecute a contempt charge, there was no conflict with the statutory requirements.
The fact that § 518(a) admits of no exception, of course, does not mean that Congress, if it so chooses, cannot exempt litigation from the otherwise blanket coverage of the statute. It does mean, however, that any such alleged exception must be scrutinized and subjected to the ordinary tools of statutory construction to determine whether Congress intended to supersede § 518(a). Indeed, Congress has enacted some provisions that suggest exceptions to the blanket coverage of § 518(a). See, e. g., Federal Courts Improvement Act of 1982, § 169, 96 Stat. 51 (preserving existing authority of the Tennessee Valley Authority “to represent itself by attorneys of its choosing,” while adding, see § 117, 96 Stat. 32, the United States Claims Court and the United States Court of Appeals for the Federal Circuit to the courts named in § 518(a)); Ethics in Government Act of 1978, § 601(a) as amended, 28 U. S. C. § 594(a)(9) (authorizing independent counsel to initiate and conduct prosecutions “in any court of competent jurisdiction . . . in the name of the United States”). See, as to the last cited Act, In re Sealed Case, 267 U. S. App. D. C. 178, 838 F. 2d 476, prob. juris, noted sub nom. Morrison v. Olson, 484 U. S. 1058 (1988). See also Stern, “Inconsistency” in Government Litigation, 64 Harv. L. Rev. 759 (1951) (discussing independent litigating authority of Interstate Commerce Commission). Without pausing here to construe the effect of any of these enactments, we note that there is no similar indication that Congress intended any such exception for a special prosecutor appointed by a court to prosecute a contempt charge, despite the fact that Federal Rule of Criminal Procedure 42(b) reflects a longstanding practice — of which we assume Congress is aware — of private prosecutions of contempt actions. See Young v. United States ex rel. Vuitton et Fils S. A., 481 U. S., at 793-796.
Similarly, nothing in § 518(a) precludes Members of Congress or the Judiciary from adding their views in litigation before this Court as intervenors or amici curiae, a practice we have long recognized, see, e. g., Bowsher v. Synar, 478 U. S. 714 (1986), and which in some instances is directly authorized by statute, see, e. g., 2 U. S. C. § 288e(a).
It may well be, as the Solicitor General contends, that even while pursuing a judicially initiated contempt prosecution, the United States Attorney remains, for all practical purposes, an officer and representative of the Executive Branch under the direction of the Attorney General. See Brief for United States as Amicus Curiae in Response to Respondents’ Motion to Dismiss 9, n. 7. But from the standpoint of § 518(a), the Solicitor’s and the special prosecutor’s interpretation would seem to permit a United States Attorney to appear in this Court on behalf of the interests at stake in a contempt prosecution.
How a case is captioned is of no significance to our holding. As we have previously observed, “courts must look behind names that symbolize the parties to determine whether a justiciable case or controversy is presented.” United States v. ICC, 337 U. S. 426, 430 (1949). Thus, even if the case had not been recaptioned by the special prosecutor upon the filing, of a petition in this Court to reflect the “adversary nature of the proceeding,” see Petitioner’s Objections to Respondents’ Motion to Dismiss 2, n. 1, we would have been required to determine whether this was a case “in which the United States is interested.” A criminal contempt prosecution in federal court, however styled, is such a ease.
