Justice Powell
delivered the opinion of the Court.
This case presents the question whether the state-action doctrine of immunity from actions under the Sherman Act applies to the grading of bar examinations by the Committee appointed by, and according to the Rules of, the Arizona Supreme Court.
I
Respondent Ronwin was an unsuccessful candidate for admission to the Bar of Arizona in 1974. Petitioners were four members of the Arizona Supreme Court’s Committee on Examinations and Admissions (Committee).1 The Arizona [561]*561Constitution vests authority in the court to determine who should be admitted to practice law in the State. Hunt v. Maricopa County Employees Merit System Comm’n, 127 Ariz. 259, 261-262, 619 P. 2d 1036, 1038-1039 (1980); see also Ariz. Rev. Stat. Ann. §32-275 (1976). Pursuant to that authority, the Arizona Supreme Court established the Committee to examine and recommend applicants for admission to the Arizona Bar.2 The Arizona Supreme Court Rules, adopted by the court and in effect in 1974,3 delegated certain responsibilities to the Committee while reserving to the court the ultimate authority to grant or deny admission. The [562]*562Rules provided that the Committee “shall examine applicants” on subjects enumerated in the Rules and “recommend to th[e] court for admission to practice” applicants found to have the requisite qualifications. Rule 28(a) (1978).4 They also authorized the Committee to “utilize such grading or scoring system as the Committee deems appropriate in its discretion,”5 and to use the Multi-State Bar Examination. Rule 28(c) VII A (1973), as amended, 110 Ariz. xxvii, xxxii (1974). Even with respect to “grading or scoring,” the court did not delegate final authority to the Committee. The Rules directed the Committee to file the formula it intended to use in grading the examination with the court 30 days prior to giving the examination.6 Also, after grading the examination and compiling the list of those applicants whom it con[563]*563sidered qualified to practice law in the State, the Committee was directed to submit its recommendations to the court for final action. Rule 28(a). Under the Rules and Arizona case law, only the court had authority to admit or deny admission.7 Finally, a rejected applicant was entitled to seek individualized review of an adverse recommendation of the Committee by filing a petition directly with the court.8 The [564]*564Rules required the Committee to file a response to such a petition and called for a prompt and fair decision on the applicant’s claims by the Arizona Supreme Court.
Ronwin took the Arizona bar examination in February 1974.9 He failed to pass, the Committee recommended to the Arizona Supreme Court that it deny him admission to the Bar, and the court accepted the recommendation. Ronwin petitioned the court to review the manner in which the Committee conducted and graded the examination. In particular, he alleged that the Committee had failed to provide him with model answers to the examination, had failed to file its grading formula with the court within the time period specified in the Rules, had applied a “draconian” pass-fail process, had used a grading formula that measured group, rather than individual, performance, had failed to test applicants on an area of the law on which the Rules required testing, and had conducted the examination in a “pressure-cooker atmosphere.” He further alleged that the Committee’s conduct constituted an abuse of discretion, deprived him of due process and equal protection, and violated the Sherman Act.10 The court denied his petition and two subsequent petitions for rehearing.11 Ronwin then sought review of the Arizona [565]*565Supreme Court’s action in this Court. We denied his petition for certiorari. 419 U. S. 967 (1974).
Some four years later, in March 1978, Ronwin filed this action in the United States District Court for the District of Arizona. Petitioners were named as defendants in the suit in their capacity as individual members of the Committee.12 Ronwin renewed his complaint that petitioners had conspired to restrain trade in violation of § 1 of the Sherman Act, 26 Stat. 209, 15 U. S. C. § 1, by “artificially reducing the numbers of competing attorneys in the State of Arizona.”13 The gist of Ronwin’s argument is that the Committee of which petitioners constituted a majority had set the grading scale on the February examination with reference to the number of new attorneys they thought desirable, rather than with reference to some “suitable” level of competence. Petitioners moved to dismiss the complaint under Federal Rule of Civil Procedure 12(b)(6) for failure to state a claim upon which [566]*566relief could be granted, and under Federal Rule of Civil Procedure 12(b)(1) for lack of subject-matter jurisdiction. In particular, petitioners alleged that, acting as a Committee, they were immune from antitrust liability under Parker v. Brown, 317 U. S. 341 (1943). Petitioners also argued that Ronwin suffered no damage from the conduct of which he complained and that the Committee's conduct had not affected interstate commerce. The District Court granted petitioners' motion after finding that the complaint failed to state a justiciable claim, that the court had no jurisdiction, and that Ronwin lacked standing.14
The Court of Appeals for the Ninth Circuit reversed the dismissal of the complaint. Ronwin v. State Bar of Arizona, 686 F. 2d 692 (1982). The Court of Appeals read the District Court’s ruling that Ronwin had failed to state a claim as a holding that bar examination grading procedures are immune from federal antitrust laws under Parker v. Brown. It reasoned that, although petitioners ultimately might be able to show that they are entitled to state-action immunity, the District Court should not have decided this issue on a Rule 12(b)(6) motion. See 686 F. 2d, at 698. The court stated that under Parker and its progeny, the mere fact that petitioners were state officials appointed by the Arizona Supreme Court was insufficient to confer state-action immunity on them. 686 F. 2d, at 697. Relying on its reading of several recent opinions of this Court,15 the Court of Appeals noted that the petitioners might be able to invoke the state-[567]*567action doctrine, but reasoned that they first must show that they were acting pursuant to a “clearly articulated and affirmatively expressed . . . state policy.” Id., at 696. Therefore, dismissal for failure to state a claim was improper. The court also held that Ronwin had standing to bring this action. The case was remanded to the District Court for further action.16
We granted certiorari to review the Court of Appeals’ application of the state-action doctrine. 461 U. S. 926 (1983). We now reverse.
II
The starting point in any analysis involving the state-action doctrine is the reasoning of Parker v. Brown. In Parker, the Court considered the antitrust implications of the California Agriculture Prorate Act — a state statute that restricted competition among food producers in California. Relying on principles of federalism and state sovereignty, the Court declined to construe the Sherman Act as prohibiting the anti-competitive actions of a State acting through its legislature:
“We find nothing in the language of the Sherman Act or in its history which suggests that its purpose was to restrain a state or its officers or agents from activities directed by its legislature. In a dual system of government in which, under the Constitution, the states are sovereign, save only as Congress may constitutionally subtract from their authority, an unexpressed purpose to nullify a state’s control over its officers and agents is not lightly to be attributed to Congress.” 317 U. S., at 350-351.
Thus, under the Court’s rationale in Parker, when a state legislature adopts legislation, its actions constitute those of [568]*568the State, see id., at 351, and ipso facto are exempt from the operation of the antitrust laws.
In the years since the decision in Parker, the Court has had occasion in several cases to determine the scope of the state-action doctrine. It has never departed, however, from Parker’s basic reasoning. Applying the Parker doctrine in Bates v. State Bar of Arizona, 433 U. S. 350, 360 (1977), the Court held that a state supreme court, when acting in a legislative capacity, occupies the same position as that of a state legislature. Therefore, a decision of a state supreme court, acting legislatively rather than judicially, is exempt from Sherman Act liability as state action. See also Goldfarb v. Virginia State Bar, 421 U. S. 773, 790 (1975). Closer analysis is required when the activity at issue is not directly that of the legislature or supreme court,17 but is carried out by others pursuant to state authorization. See, e. g., Community Communications Co. v. Boulder, 455 U. S. 40 (1982) (municipal regulation of cable television industry); California Retail Liquor Dealers Assn. v. Midcal Aluminum, Inc., 445 U. S. 97 (1980) (private price-fixing arrangement authorized by State); New Motor Vehicle Board of California v. Orrin W. Fox Co., 439 U. S. 96 (1978) (new franchises controlled by state administrative board). In such cases, it becomes important to ensure that the anti-competitive conduct of the State’s representative was contemplated by the State. Lafayette v. Louisiana Power & Light Co., 435 U. S. 389, 413-415 (1978) (opinion of Brennan, J.); see New Mexico v. American Petrofina, Inc., 501 F. 2d 363, 369-370 (CA9 1974). If the replacing of entirely free competition with some form of regulation or restraint was not authorized or approved by the State then the rationale of Parker is inapposite. As a result, in cases [569]*569involving the anticompetitive conduct of a nonsovereign state representative the Court has required a showing that the conduct is pursuant to a “clearly articulated and affirmatively expressed state policy” to replace competition with regulation. Boulder, supra, at 54. The Court also has found the degree to which the state legislature or supreme court supervises its representative to be relevant to the inquiry. See Midcal Aluminum, supra, at 105; Goldfarb, supra, at 791. When the conduct is that of the sovereign itself, on the other hand, the danger of unauthorized restraint of trade does not arise. Where the conduct at issue is in fact that of the state legislature or supreme court, we need not address the issues of “clear articulation” and “active supervision.”
Pursuant to the State Constitution, the Arizona Supreme Court has plenary authority to determine admissions to the Bar.18 Therefore, the first critical step in our analysis must be to determine whether the conduct challenged here is that of the court. If so, the Parker doctrine applies and Ronwin has no cause of action under the Sherman Act.
HH H-1 t — I
At issue here is the Arizona plan of determining admissions to the bar, and petitioners’ use thereunder of a grading formula. Ronwin has alleged that petitioners conspired to use [570]*570that formula to restrain competition among lawyers.19 His argument is that, although petitioners qualified as state officials in their capacity as members of the Committee, they acted independently of the Arizona Supreme Court. As a result, the argument continues, the Committee's actions are those of a Supreme Court representative, rather than those of the court itself, and therefore are not entitled to immunity.
We cannot agree that the actions of the Committee can be divorced from the Supreme Court’s exercise of its sovereign powers. The Court’s opinion in Bates v. State Bar of Arizona, 433 U. S., at 360, is directly pertinent.20 In Bates, two [571]*571attorneys were suspended temporarily from the practice of law in Arizona for violating a disciplinary rule of the American Bar Association (ABA) that prohibited most lawyer advertising. The Arizona Supreme Court had incorporated the ABA’s advertising prohibition into the local Supreme Court Rules.21 Those Rules also provided that the Board of Governors of the Arizona State Bar Association, acting on the recommendation of a local Bar disciplinary committee, could recommend the censure or suspension of a member of the Bar for violating the advertising ban. Under the Rules, the Board of Governor’s recommendation automatically would become effective if the aggrieved party did not object to the recommendation within 10 days. If the party objected, he was entitled to have the Arizona Supreme Court review the findings and recommendations of the Board of Governors and the local committee. The plaintiffs challenged the Rule on Sherman Act and First Amendment grounds. This Court ultimately concluded that the ABA Rule violated the First Amendment, but it first held that the State Bar Association was immune from Sherman Act liability because its enforcement of the disciplinary Rules was state action. In reaching this conclusion, the Court noted that, although only the State Bar was named as a defendant in the suit, the suspended attorneys’ complaint was with the State. The Court stated:
“[T]he appellants’ claims are against the State. The Arizona Supreme Court is the real party in interest; it adopted the rules, and it is the ultimate trier of fact and law in the enforcement process. In re Wilson, 106 [572]*572Ariz. 34, 470 P. 2d 441 (1970). Although the State Bar plays a part in the enforcement of the rules, its role is completely defined by the court; the [State Bar] acts as the agent of the court under its continuous supervision.” Id., at 361.
The opinion and holding in Bates with respect to the state-action doctrine were unanimous.
The logic of the Court’s holding in Bates applies with greater force to the Committee and its actions. The petitioners here were each members of an official body selected and appointed by the Arizona Supreme Court. Indeed, it is conceded that they were state officers. The court gave the members of the Committee discretion in compiling and grading the bar examination, but retained strict supervisory powers and ultimate full authority over its actions. The Supreme Court Rules specified the subjects to be tested, and the general qualifications required of applicants for the Bar. With respect to the specific conduct of which Ronwin complained — establishment of an examination grading formula— the Rules were explicit. Rule 28(c) VII A authorized the Committee to determine an appropriate “grading or scoring system” and Rule 28(c) VII B required the Committee to submit its grading formula to the Supreme Court at least 30 days prior to the examination.22 After giving and grading the examination, the Committee’s authority was limited to [573]*573making recommendations to the Supreme Court. The court itself made the final decision to grant or deny admission to practice. Finally, Rule 28(c) XII F provided for a detailed mandatory review procedure by which an aggrieved candidate could challenge the Committee’s grading formula.23 In light of these provisions and the Court’s holding and reasoning in Bates, we conclude that, although the Arizona Supreme Court necessarily delegated the administration of the admissions process to the Committee, the court itself approved the particular grading formula and retained the sole authority to determine who should be admitted to the practice of law in Arizona. Thus, the conduct that Ronwin challenges was in reality that of the Arizona Supreme Court. See Bates, 433 U. S., at 361. It therefore is exempt from Sherman Act liability under the state-action doctrine of Parker v. Brown.24
[574]*574At oral argument, Ronwin suggested that we should not attribute to the Arizona Supreme Court an intent to approve the anticompetitive activity of petitioners in the absence of proof that the court was aware that petitioners had devised a grading formula the purpose of which was to limit the number of lawyers in the State. This argument misconceives the basis of the state-action doctrine. The reason that state action is immune from Sherman Act liability is not that the State has chosen to act in an anticompetitive fashion, but that the State itself has chosen to act. “There is no suggestion of a purpose to restrain state action in the [Sherman] Act’s legislative history.” Parker, 317 U. S., at 351. The Court did not suggest in Parker, nor has it suggested since, that a state action is exempt from antitrust liability only if the sovereign acted wisely after full disclosure from its subordinate officers. The only requirement is that the action be that of “the State acting as a sovereign.” Bates, supra, at 360. The action at issue here, whether anticompetitive or not, clearly was that of the Arizona Supreme Court.25

The dissenting opinion of Justice Stevens would, if it were adopted, alter dramatically the doctrine of state-action immunity. We therefore reply directly. The dissent concedes, as it must, that “the Arizona Supreme Court exercises sovereign power with respect to admission to the Arizona Bar,” and “if the challenged conduct were that of the court, it would be immune under Parker. ” Post, at 588. It also is con[575]*575ceded that the members of the court’s Commitee on Examinations and Admissions — petitioners here — are state officers. These concessions are compelled by the Court’s decision in Bates, and we think they dispose of Ronwin’s contentions.
In its effort to distinguish Bates, the dissent notes that the Arizona Supreme Court “is not a petitioner [in this case], nor was it named as a defendant in respondent’s complaint,” and “because respondent is not challenging the conduct of the Arizona Supreme Court, Parker [v. Brown] is simply inapplicable.” Post, at 588, 589. The dissent fails to recognize that this is precisely the situation that existed in Bates. In that case, the Supreme Court of Arizona was not a party in this Court, nor was it named as a defendant by the complaining lawyers. Yet, in our unanimous opinion, we concluded that the claims by appellants in Bates were “against the State,” and that the “Arizona Supreme Court [was] the real party in interest; it adopted the rules, and it [was] the ultimate trier of fact and law in the enforcement process.” Bates v. State Bar of Arizona, supra, at 361; see supra, at 571.26
The core argument of the dissent is that Ronwin has challenged only the action of the Committee and not that of the Arizona Supreme Court. It states that “there is no claim that the court directed [the Committee] to artificially reduce the number of lawyers in Arizona,” and therefore the Committee cannot assert the sovereign’s antitrust immunity. Post, at 592 (emphasis in original). The dissent does not acknowledge that, conspire as they might, the Committee could not reduce the number of lawyers in Arizona.27 Only [576]*576the Arizona Supreme Court had the authority to grant or deny admission to practice in the State.28 As in Bates “[t]he Arizona Supreme Court is the real party in interest.” 433 U. S., at 361.
The dissent largely ignores the Rules of the Arizona Supreme Court.29 A summary of the court’s commands suggests why the dissent apparently prefers not to address them. The Arizona Supreme Court established the Committee for the sole purpose of examining and recommending applicants for admission to the Bar. Rule 28(a). Its Rules provided: “The examination and admission of applicants . . . shall conform to this Rule. . . . The committee shall examine applicants and recommend [qualified applicants] to this court. . . . Two examinations will be held each year. . . .” Ibid.; Rule 28(c) VI (1973), as amended, 110 Ariz. xxxii (1974) (emphasis added). The Rules also specified the subjects to be tested and required the Committee to submit its grading formula to the court in advance of each examination. Rule 28(c) VII (1973), as amended, 110 Ariz. xxxii (1974).
As a further safeguard, a disappointed applicant was accorded the right to seek individualized review by filing a petition directly with the court — as Ronwin did unsuccessfully. Pursuant to Rule 28(c) XII F, Ronwin filed a complaint with the court that contained a plethora of charges [577]*577including the substance of the complaint in this case. The court denied his petition as well as two petitions for rehearing. See supra, at 564. Thus, again there was state action by the court itself explicitly rejecting Ronwin’s claim.30 Finally, the [578]*578case law, as well as the Rules, makes clear that the Arizona Supreme Court made the final decision on each applicant.31 See n. 6, supra. Unlike the actions of the Virginia State Bar in Goldfarb, the actions of the Committee are governed by the court’s Rules. Those Rules carefully reserve to the court the authority to make the decision to admit or deny, and that decision is the critical state action here.32 See Bates, 433 [579]*579U. S., at 359-361. Our opinion, therefore, also is wholly consistent with the Court’s reasoning in Lafayette v. Louisiana Power & Light Co., 435 U. S. 389 (1978) and Community Communications Co. v. Boulder, 455 U. S. 40 (1982).33
Our holding is derived directly from the reasoning of Parker and Bates. Those cases unmistakably hold that, where the action complained of — here the failure to admit [580]*580Ronwin to the Bar — was that of the State itself, the action is exempt from antitrust liability regardless of the State’s motives in taking the action. Application of that standard to the facts of this case requires that we reverse the judgment of the Court of Appeals.
The reasoning adopted by the dissent would allow Sherman Act plaintiffs to look behind the actions of state sovereigns and base their claims on perceived conspiracies to restrain trade among the committees, commissions, or others who necessarily must advise the sovereign. Such a holding would emasculate the Parker v. Brown doctrine. For example, if a state legislature enacted a law based on studies performed, or advice given, by an advisory committee, the dissent would find the State exempt from Sherman Act liability but not the committee. A party dissatisfied with the new law could circumvent the state-action doctrine by alleging that the committee’s advice reflected an undisclosed collective desire to restrain trade without the knowledge of the legislature. The plaintiff certainly would survive a motion to dismiss — or even summary judgment — despite the fact that the suit falls squarely within the class of cases found exempt from Sherman Act liability in Parker.34
[581]*581In summary, this case turns on a narrow and specific issue: who denied Ronwin admission to the Arizona Bar? The dissent argues, in effect, that since there is no court order in the record, the denial must have been the action of the Committee. This argument ignores the incontrovertible fact that under the law of Arizona only the State Supreme Court had authority to admit or deny admission to practice law:
“[It] is not the function of the committee to grant or deny admission to the bar. That power rests solely in the Supreme Court. . . .” Application of Burke, 87 Ariz. 336, 338, 351 P. 2d 169, 171 (1960) (see n. 30, supra).
Thus, if the dissent’s argument were accepted all decisions made with respect to admissions and denials of those who took the examination in February 1974 are void. Ronwin did not allege that he alone was a victim: his complaint avers [582]*582that he “was among those artificially prevented from entering into competition as an attorney in the state of Arizona ” by the Committee’s action with respect to the February 1974 examination. We are unwilling to assume that the Arizona Supreme Court failed to comply with state law, and allowed the Committee alone to make the decisions with respect to the February 1974 examination. In any event, the record is explicit that Ronwin’s postexamination petition complaining about his denial was rejected by an order of the Arizona Supreme Court. That there was state action at least as to Ronwin could not be clearer.
V
We conclude that the District Court properly dismissed Ronwin’s complaint for failure to state a claim upon which relief can be granted. Therefore, the judgment of the Court of Appeals is
Reversed.
Justice Rehnquist took no part in the decision of this case. Justice O’Connor took no part in the consideration or decision of this case.
