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 *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 *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*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 *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 *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 *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-*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 *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 *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 *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 *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 *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 *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
*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
> HH
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*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 *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 *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 *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 *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 *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
*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 *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.
Although petitioners represent only four of the seven members of the Committee at the time of the February 1974 bar examination, Ronwin named all seven members in his original complaint. Apparently, three of *561the original defendants to this action did not join, for reasons not apparent, the petition for certiorari in this Court. There is no claim that these members of the Committee failed to participate in or dissented from the actions of the Committee.
The procedure in Arizona is not unique to that State. In recent years, the burgeoning number of candidates for admission to practice law and the increased complexity of the subjects that must be tested have combined to make grading and administration of bar examinations a burdensome task. As a result, although the highest court in each State retains ultimate authority for granting or denying admission to the bar, each of those courts has delegated to a subordinate committee responsibility for preparing, grading, and administering the examination. See F. Klein, S. Leleiko, & J. Mavity, Bar Admission Rules and Student Practice Rules 30-33 (1978).
The parties disagree on the wording of the Rules at the time Ronwin took the bar examination. The disagreement centers around the effective date of some amendments promulgated in 1974. Petitioners contend that the amendments took effect before Ronwin took the February 1974 bar examination; Ronwin submits that they became effective in March 1974. Ronwin concedes that the Supreme Court order amending the Rules provided that the amendments would become effective in January 1974. Notwithstanding this directive, he argues that Ariz. Rev. Stat. Ann. § 12-109 (1982) provided that amendments to the Supreme Court’s Rules may not become effective until 60 days after publication and distribution. Since the Supreme Court released the amendments on January 11, Ronwin submits that the earliest possible effective date was March 12.
Ronwin has misread § 12-109. That section only applied to Rules that regulated pleading, practice, and procedure in judicial proceedings in state courts. By its terms, the statute did not limit the jurisdiction of the Arizona Supreme Court to establish the terms of admission to practice law in the State. See Ariz. Rev. Stat. Ann. § 32-275 (1976).
Rule 28(a) provided:
“Examination and Admission. . . . The examination and admission of applicants for membership in the State Bar of Arizona shall conform to this Rule. For such purpose, a committee on examinations and admissions consisting of seven active members of the state bar shall be appointed by this court. . . . The committee shall examine applicants and recommend to this court for admission to practice applicants who are found by the committee to have the necessary qualifications and to fulfill the requirements prescribed by the rules of the board of governors as approved by this court respecting examinations and admissions. . . . The court will then consider the recommendations and either grant or deny admission.”
According to Ronwin’s complaint, the Committee announced before the February examination that the passing grade on the test would be 70, but it assigned grades using a scaled scoring system. Under this system, the examinations were graded first without reference to any grading scale. Thus, each examination was assigned a “raw score” based on the number of correct answers. The Committee then converted the raw score into a score on a scale of zero to 100 by establishing the raw score that would be deemed the equivalent of “seventy.” See n. 19, infra.
Rule 28(c) VII B provided:
“The Committee on Examinations and Admissions will file with the Supreme Court thirty (30) days before each examination the formula upon which the Multi-State Bar Examination results will be applied with the other portions of the total examination results. In addition the Committee will file with the Court thirty (30) days before each examination the proposed formula for grading the entire examination.” 110 Ariz., at xxxii.
See n. 4, supra; Application of Courtney, 83 Ariz. 231, 233, 319 P. 2d 991, 993 (1957) (“[T]his court may in the exercise of its inherent powers, admit to the practice of law with or without favorable action by the Committee”); Hackin v. Lockwood, 361 F. 2d 499, 501 (CA9) (“[W]e find the power to grant or deny admission is vested solely in the Arizona Supreme Court”), cert. denied, 385 U. S. 960 (1966). See also Application of Burke, 87 Ariz. 336, 351 P. 2d 169 (1960).
Rule 28(c) XII F provided:
“1. An applicant aggrieved by any decision of the Committee
“(A) Refusing permission to take an examination upon the record;
“(B) Refusing permission to take an examination after hearing;
“(C) For any substantial cause other than with respect to a claimed failure to award a satisfactory grade upon an examination;
“may within 20 days after such occurrence file a verified petition with this Court for a review. . . .
“2. A copy of said petition shall be promptly served upon the chairman or some member of the Committee and the Committee shall within 15 days of such service transmit said applicant’s file and a response to the petition fully advising this Court as to the Committee’s reasons for its decision and admitting or contesting any assertions made by applicant in said petition. Thereupon this Court shall consider the papers so filed together with the petition and response and make such order, hold such hearings and give such directions as it may in its discretion deem best adapted to a prompt and fair decision as to the rights and obligations of applicant judged in the light of the Committee’s and this Court’s obligation to the public to see that only qualified applicants are admitted to practice as attorneys at law.” 110 Ariz., at xxxv-xxxvi.
Under Rule 28(c) XII G, an applicant who wished to challenge the grading of an answer to a particular question first had to submit his claim to the Committee for review. The applicant was entitled to request Arizona Supreme Court review only if three members of the Committee agreed with the applicant that his answer had not received the grade it deserved. The Rule also provided that the court could grant or deny such a request in its discretion. Id., at xxxvi-xxxvii.
The Arizona Supreme Court Rules instructed the Committee to give two examinations each year — one in July and one in February. Id., at xxxii.
He also alleged that the Committee had violated his constitutional rights by refusing, after the grades had been released, to provide him with the questions and answers to the Multi-State portion of the examination.
Rule 28(c) XII F 2 provides, with respect to the petition of an aggrieved applicant, that the Arizona Supreme Court “shall consider” the petition and response, and “hold such hearings and give such directions as it may in its discretion deem best adapted to a prompt and fair decision.” 110 Ariz., at xxxvi. Ronwin makes no claim that the court failed to comply with its Rules, although — of course — he disagrees with the court’s judgment denying his petition. Thus, the court’s denial of his petition must be construed as a consideration and rejection of the arguments made in the petition — including Ronwin’s claim that the Sherman Act was violated.
Also named as defendants were petitioners’ spouses and the Arizona State Bar. The District Court dismissed the suit as to these defendants and the Court of Appeals affirmed the dismissal. Ronwin v. State Bar of Arizona, 686 F. 2d 692, 694, n. 1 (CA91981). Ronwin challenged this aspect of the Court of Appeals’ opinion in a conditional cross-petition for certiorari. We denied the cross-petition. Ronwin v. Hoover, 461 U. S. 938 (1983).
The averment of a Sherman Act violation in Ronwin’s complaint is as follows:
“The aforesaid conduct [the “scoring system or formula,” see n. 4, supra], which the Defendants entered into as a conspiracy or combination, was intended to and did result in a restraint of trade and commerce among the Several States by artificially reducing the numbers of competing attorneys in the State of Arizona; and, in further consequence of said conduct, Plaintiff was among those artificially prevented from entering into competition as an attorney in the State of Arizona and thereby further deprived of the right to compete as an attorney for the legal business deriving from or involving the Several States of the United States, including Arizona.” App. 10-11.
The adequacy of these conclusory averments of intent is far from certain. The Court of Appeals, however, found the complaint sufficient. Accordingly, we address the “state action” issue.
The District Court also denied Ronwin’s motion requesting the trial judge to recuse himself. The Court of Appeals held that the District Court had not abused its discretion in denying the motion. 686 F. 2d., at 701. We declined to review that finding. Ronwin v. Hoover, supra.
Community Communications Co. v. Boulder, 455 U. S. 40 (1982); California Retail Liquor Dealers Assn. v. Midcal Aluminum, Inc., 445 U. S. 97 (1980); New Motor Vehicle Board of California v. Orrin W. Fox Co., 439 U. S. 96 (1978); Lafayette v. Louisiana Power & Light Co., 435 U. S. 389 (1978).
The Court of Appeals also held that the District Court should give Ronwin the opportunity to show that petitioners’ actions sufficiently affected interstate commerce to fall within the jurisdiction of the Sherman Act. Petitioners did not seek review of this holding.
This case does not present the issue whether the Governor of a State stands in the same position as the state legislature and supreme court for purposes of the state-action doctrine.
Ronwin does not dispute that regulation of the bar is a sovereign function of the Arizona Supreme Court. In Bates v. State Bar of Arizona, 433 U. S. 350, 361 (1977), the Court noted that “the regulation of the activities of the bar is at the core of the State’s power to protect the public.” Likewise, in Goldfarb v. Virginia State Bar, 421 U. S. 773, 792 (1975), the Court stated: “The interest of the States in regulating lawyers is especially great since lawyers are essential to the primary governmental function of administering justice, and have historically been ‘officers of the courts.’” See also In re Griffiths, 413 U. S. 717, 722-723 (1973). Few other professions are as close to “the core of the State’s power to protect the public.” Nor is any trade or other profession as “essential to the primary governmental function of administering justice.”
Ronwin’s complaint, see supra, at 565, focuses on the grading formula as the means used to “restrain competition.” He describes it as follows: “The Defendants did not grade on a Zero to One Hundred (0 to 100) scale; rather they used a “raw score” system. After the raw scores were known, the Defendants picked a particular raw score value as equal to the passing grade of Seventy (70). Thereby the number of Bar applicants who would receive a passing grade depended upon the exact raw score value chosen as equal to Seventy (70); rather than achievement by each Bar applicant of a pre-set standard.” App. 10.
Apparently Ronwin was trying to describe a “procedure commonly known as test standardization” or “sealed scoring.” See Brief for State Bar of California as Amicus Curiae 7. This method of scoring, viewed as the fairest by the Educational Testing Service (ETS) for the Multistate Bar Examination (MBE), see S. Duhl, The Bar Examiners’ Handbook 61-62 (2d ed. 1980), published by The National Conference of Bar Examiners, is described as follows:
“In addition to the ‘raw’ scores (number of correct answers), ETS reports a ‘scaled’ score for each applicant. In a series of tests, such as the MBE, which are intended to measure levels of competence, it is important to have a standardized score which represents the same level of competence from test to test. The raw score is not dependable for this purpose since the level of difficulty varies from test to test. It is not possible to draft two tests of exactly the same level of difficulty. Scaled scores are obtained by reusing some questions from earlier tests which have been standardized. A statistical analysis of the scores on the reused questions determines how many points are to be added to or subtracted from the raw score to provide an applicant’s scaled score. Thus a particular scaled score represents the same level of competence from examination to examination.”
Although the Court of Appeals recognized the similarity between this case and Bates, it found the facts in Goldfarb v. Virginia State Bar, supra, *571to be more analogous. The court’s reliance on Goldfarb was misplaced. As the dissent of Judge Ferguson noted, Goldfarb involved procedures that were not approved by the State Supreme Court or the state legislature. In contrast, petitioners here performed functions required by the Supreme Court Rules and that are not effective unless approved by the court itself.
Rule 29(a) of the Supreme Court of Arizona provided: “The duties and obligations of members [of the Bar] shall be as prescribed by the Code of Professional Responsibility of the American Bar Association. . .
Following petitioners’ request for a rehearing in the Court of Appeals, the parties debated whether and to what extent the Committee complied with this Rule. For purposes of determining the application of the state-action doctrine, it is sufficient that the Rules contained an enforceable provision calling for submission of the grading formula. Moreover, the Rules contained a review procedure that allowed an aggrieved applicant to bring to the Supreme Court’s attention any failure of the Committee to comply with the filing requirements in Rule 28(c) VIIB. The record reveals that Ronwin, in fact, alleged in his petition for review in the Arizona Supreme Court that the Committee had not filed its grading formula within the time provided in the Rule. The court rejected the petition. See supra, at 564.
This procedure allowed a disappointed applicant to challenge “[f ]or any substantial cause” a Committee decision other than “a claimed failure to award a satisfactory grade.” Rule 28(c) XII F 1(C). As we have noted, Ronwin took full advantage of Rule 28(c) XII F 1(C) in his challenge to the action of the Committee and the court. See supra, at 564. He did not, however, challenge the particular grade assigned to any of his answers.
The Solicitor General, on behalf of the United States as amicus, contends that our recent opinion in Community Communications Co. v. Boulder, 455 U. S. 40 (1982), precludes a finding that the Committee’s action was attributable to the Arizona Supreme Court. Contrary to the Solicitor General’s suggestion, our reasoning in Boulder supports the conclusion we reach today. In Boulder, we reiterated the analysis of Justice Brennan’s opinion in Lafayette v. Louisiana Power & Light Co., 435 U. S. 389 (1978). We noted that the state-action doctrine is grounded in concepts of federalism and state sovereignty. 455 U. S., at 54. We stated that Parker did not confer state-action immunity automatically on municipalities, because the actions of a municipality are not those of the State itself. 455 U. S., at 53. Under our holding in Boulder, municipalities may be eligible for state-action immunity, but only “to the extent that they ac[t] pursuant to a clearly articulated and affirmatively expressed state policy.” Id., at 54; see also Lafayette, supra, at 411-412 (opinion of Brennan, J.). Consistent with our reasoning in Boulder, our decision today rests on our conclusion that the conduct Ronwin complains of clearly is the action of the State. Bates is explicit authority for this conclusion.
Our holding that petitioners’ conduct is exempt from liability under the Sherman Act precludes the need to address petitioners’ contention that they are immune from liability under the Noerr-Pennington doctrine. See Mine Workers v. Pennington, 381 U. S. 657 (1965); Eastern Railroad Presidents Conference v. Noerr Motor Freight, Inc., 365 U. S. 127 (1961).
We also do not address Ronwin’s contention that the Arizona method of limiting bar admissions violates the Fifth and Fourteenth Amendments. As Ronwin concedes, he made this argument for the first time in his response to petitioners’ motion for rehearing in the Court of Appeals. His failure to raise this issue in a timely manner precludes our consideration.
The authority of the Arizona Supreme Court to determine who shall be admitted to the Bar, and by what procedure, is even more clearly defined than the role of that court in Bates. In that case, State Bar Committee members were not appointed by the court, and the court did not expressly accept or reject each of the Committee’s actions.
Under Arizona law, the responsibility is on the court — and only on it— to admit or deny admission to the practice of law. This Court certainly cannot assume that the Arizona court, in the exercise of its specifically reserved power under its Rules, invariably agrees with its Committee. Even if it did, however, it would be action of the sovereign.
Even if Committee members had decided to grade more strictly, under the grading formula approved by the court, for the purpose of reducing the total number of lawyers admitted to practice, the court knew and approved the number of applicants. This was the definitive action. There is nothing in the state-action doctrine, or in antitrust law, that permits us to question the motives for the sovereign aetion of the court.
The dissent recites the provisions of the Rules regulating the composition and origin of the Committee and notes that the Rules require the Committee to recommend qualified applicants to the Supreme Court. Post, at 586. The dissent does not mention, however, several critical provisions, summarized in the text infra, that articulate the Arizona Supreme Court’s intent to retain full authority over, and responsibility for, the bar admissions process.
The dissent states, post, at 591-592, n. 15, that we “advanced the theory that the relevant ‘state action' ” was the State Supreme Court’s denial of Ronwin’s postexamination petitions filed with the court. (Emphasis supplied.) The dissent is inaccurate. Our holding is based on the court’s direct participation in every stage of the admissions process, including retention of the sole authority to admit or deny. The critical action in this case was the court’s decision to deny Ronwin admission to the Bar. The dissent’s suggestion that the Arizona Supreme Court never made this decision simply ignores Arizona law. The Arizona Supreme Court has stated on several occasions that it, and not the Committee, makes the decision to admit or deny admission to applicants. In Application of Burke, 87 Ariz., at 338, 351 P. 2d, at 171-172, the court stated:
“[I]t is not the function of the committee to grant or deny admission to the bar. That power rests solely in the Supreme Court. . . . The committee’s bounden duty is to ’put up the red flag’ as to those applicants about whom it has some substantial doubt. If such doubt exists, then its recommendation should be withheld. The applicant may feel that any questions raised as to his character or qualifications are without substance. In such case, he may apply directly to this court for admission. In the final analysis — it being a judicial function — we have the duty of resolving those questions, one way or the other. . . .” (Emphasis supplied.)
In a similar vein, the court stated in Application of Levine, 97 Ariz. 88, 92, 397 P. 2d 205, 207 (1964):
“If the committee fails to recommend the admission of an applicant, he may challenge the committee’s conclusions by an original application to this Court.... This Court will direct the committee to show cause why the applicant has been refused a favorable recommendation and on the applicant’s petition and the committee’s response, using our independent judgment, de novo determine whether the necessary qualifications have been shown.”
See also Application of Kiser, 107 Ariz. 326, 327, 487 P. 2d 393, 394 (1971).
Thus, the Arizona Supreme Court repeatedly has affirmed its responsibility as the final decisionmaker on admissions to the Bar. The dissent, relying on the absence in the record before us of a specific order of the court at the time Ronwin was not admitted, nevertheless would have us hold that the Committee rather than the court made the final decisions as *578to admissions and denials of the applicants who took the examination in February 1974. If the dissent were correct, there would have been no valid action with respect to those who took that examination since, under Arizona law, the Committee had no independent power to act. Ronwin’s complaint makes no such extreme averment, and certainly this Court will not assume that the Supreme Court of Arizona failed to discharge its responsibility. Moreover, as we have noted, supra, at 576-577, Ronwin’s claims were specifically rejected by the court.
It is true, of course, that framing examination questions and particularly the grading of the examinations involved the exercise of judgment and discretion by the examiners. This discretion necessarily was delegated to the Arizona Committee, just as it must be unless state supreme courts themselves undertake the grading. By its Rules, the Arizona Supreme Court gave affirmative directions to the Committee with respect to every nondiscretionary function, reserving the ultimate authority to control the number of lawyers admitted to the Arizona Bar. Ronwin avers a “conspiracy to limit the number” of applicants admitted. He makes no claim of animus or discriminatory intent with respect to himself.
Ronwin apparently would have us believe that grading examinations is an exact science that separates the qualified from the unqualified applicants. Ideally, perhaps, this should be true. But law schools and bar examining committees must identify a grade below which students and applicants fail to pass. No setting of a passing grade or adoption of a grading formula can eliminate — except on multiple choice exams — the discretion exercised by the grader. By its very nature, therefore, grading examinations does not necessarily separate the competent from the incompetent or — except very roughly — identify those qualified to practice law and those not qualified. At best, a bar examination can identify those applicants who are more qualified to practice law than those less qualified.
Justice Stevens’ dissent states that “[a]ny possible claim that the challenged conduct is that of the State Supreme Court is squarely foreclosed by Goldfarb v. Virginia State Bar, 421 U. S. 773 (1975).” Post, at 589. At issue in Goldfarb was a Sherman Act challenge to minimum-fee schedules maintained by the Fairfax County Bar Association and enforced *579by the Virginia State Bar. In Goldfarb, state law did not refer to lawyers’ fees, the Virginia Supreme Court Rules did not direct the State Bar to supply fee schedules, and the Supreme Court did not approve the fee schedules established by the State Bar. To the contrary, the court “directed lawyers not ‘to be controlled’ by fee schedules.” 421 U. S., at 789. Thus, even though the State Bar was a state agency, the Court concluded that “it cannot fairly be said that the State of Virginia through its Supreme Court Rules required the anticompetitive activities of either respondent.” Id., at 790. As is evident from the provisions in the Arizona Supreme Court Rules, this case arises under totally different circumstances, although the relevant legal principles are the same. The dissent’s reliance on Goldfarb simply misreads the decision in that case.
The dissent relies on Boulder, arguing that the “clearly articulated and affirmatively expressed state policy” does not exist in this case. Post, at 594-596. What the dissent overlooks is that the Court in Boulder was careful to say that action is not “exempt from antitrust scrutiny unless it constitutes the action of the State of Colorado itself in its sovereign capacity, see Parker, or unless it constitutes municipal action in furtherance or implementation of clearly articulated and affirmatively expressed state policy, see City of Lafayette....” 455 U. S., at 52. Thus, unlike the dissent here, Justice BRENNAN in Boulder was careful to distinguish between action by the sovereign itself and action taken by a subordinate body.
The dissent also cites Cantor v. Detroit Edison Co., 428 U. S. 579 (1976), and California Retail Liquor Dealers Assn. v. Midcal Aluminum, Inc., 445 U. S. 97 (1980), as presenting situations analogous to the action of the Arizona Supreme Court. This argument overlooks the fundamental difference between this case and the several cases cited by respondent. In each of those cases, it was necessary for the Court to determine whether there had been a clearly articulated and affirmatively expressed state policy because the challenged conduct was not that of the State “acting as sovereign.” Here, as we have noted above, the Arizona Supreme Court, acting in its sovereign capacity, made the final decision to deny admission to Ronwin. See n. 30, supra.
The amicus curiae brief of the National Conference of Bar Examiners points out that many States have bar admission processes like those at issue in this case. See Brief for National Conference of Bar Examiners as Amicus Curiae 1, 2, 8. Typically, the state supreme court is the ultimate decisionmaker and a committee or board conducts the examinations pursuant to court rules. It is customary for lawyers of recognized standing and integrity to serve on these bodies, usually as a public duty and with little or no compensation. See S. Duhl, The Bar Examiner’s Handbook 95, 99 (2d ed. 1980). In virtually all States, a significant percentage of those who take the bar examination fail to pass. See 1982 Bar Examination Statistics, 52 Bar Examiner 24-26 (1983). Thus, every year, there are thousands of aspirants who, like Ronwin, are disappointed. For example, in 1974 (the year Ronwin first took the Arizona bar examination), of the 43,798 applicants who took bar examinations nationwide, 10,440 failed to pass. 44 Bar Examiner 115 (1975). The National Conference of Bar Examiners, in its amicus brief, cautions that affirmance of the Court of *581Appeals in this case could well invite numerous suits. It is no answer to say that, of course, such suits are likely to be frivolous. Ronwin, who failed the bar in 1974, has been litigating his claim for a decade on the basis of a complaint that basically challenges the motive of the Arizona Committee. His claim is that the grading formula was devised for the purpose of limiting competition. If such an allegation is sufficient to survive a motion to dismiss, examining boards and committees would have to bear the substantial “discovery and litigation burdens” attendant particularly upon refuting a charge of improper motive. See Areeda, Antitrust Immunity for “State Action” after Lafayette, 95 Harv. L. Rev. 435, 451 (1981). Moreover, Ronwin has brought a suit for damages under the Sherman Act, with the threat of treble damages. There can be no question that the threat of being sued for damages — particularly where the issue turns on subjective intent or motive — will deter “able citizens” from performing this essential public service. See Harlow v. Fitzgerald, 457 U. S. 800, 814 (1982). In our view, as the action challenged by Ronwin was that of the State, the motive of the Committee in its recommendations to the court was immaterial. We nevertheless think, particularly in view of the decision below, that the consequences of an affirmance should be understood. The consequences of reversal by the Court today will have only a limited effect. Our attention has not been drawn to any trade or other profession in which the licensing of its members is determined directly by the sovereign itself— here the State Supreme Court.
