JUSTICE BRENNAN delivered the opinion of the Court.

The question presented in this case, in which the District Court for the District of Colorado granted preliminary injunctive relief, is whether a "home rule" municipality, granted by the state constitution extensive powers of self-government in local and municipal matters, enjoys the "state action" exemption from Sherman Act liability announced in Parker v. Brown, 317 U. S. 341 (1943).

I

Respondent city of Boulder is organized as a "home rule" municipality under the Constitution of the State of Colorado.^[1] The city is thus entitled to exercise "the full right of self-government in both local and municipal matters," and with respect to such matters the City Charter and ordinances *44 supersede the laws of the State. Under that Charter, all municipal legislative powers are exercised by an elected City Council.^[2] In 1964 the City Council enacted an ordinance granting to Colorado Televents, Inc., a 20-year, revocable, nonexclusive permit to conduct a cable television business within the city limits. This permit was assigned to petitioner in 1966, and since that time petitioner has provided cable television service to the University Hill area of Boulder, an area where some 20% of the city's population lives, and where, for geographical reasons, broadcast television signals cannot be received.

From 1966 until February 1980, due to the limited service that could be provided with the technology then available, petitioner's service consisted essentially of retransmissions of programming broadcast from Denver and Cheyenne, Wyo. Petitioner's market was therefore confined to the University Hill area. However, markedly improved technology became available in the late 1970's, enabling petitioner to offer many more channels of entertainment than could be provided by local broadcast television.^[3] Thus presented with an opportunity *45 to expand its business into other areas of the city, petitioner in May 1979 informed the City Council that it planned such an expansion. But the new technology offered opportunities to potential competitors, as well, and in July 1979 one of them, the newly formed Boulder Communications Co. (BCC),^[4] also wrote to the City Council, expressing its interest in obtaining a permit to provide competing cable television service throughout the city.^[5]

The City Council's response, after reviewing its cable television policy,^[6] was the enactment of an "emergency" ordinance *46 prohibiting petitioner from expanding its business into other areas of the city for a period of three months.^[7] The City Council announced that during this moratorium it planned to draft a model cable television ordinance and to invite new businesses to enter the Boulder market under its terms, but that the moratorium was necessary because petitioner's continued expansion during the drafting of the model ordinance would discourage potential competitors from entering the market.^[8]

Petitioner filed this suit in the United States District Court for the District of Colorado, and sought, inter alia, a preliminary injunction to prevent the city from restricting petitioner's *47 proposed business expansion, alleging that such a restriction would violate § 1 of the Sherman Act.^[9] The city responded that its moratorium ordinance could not be violative of the antitrust laws, either because that ordinance constituted an exercise of the city's police powers, or because Boulder enjoyed antitrust immunity under the Parker doctrine. The District Court considered the city's status as a home rule municipality, but determined that that status gave autonomy to the city only in matters of local concern, and that the operations of cable television embrace "wider concerns, including interstate commerce . . . [and] the First Amendment rights of communicators." 485 F. Supp. 1035, 1038-1039 (1980). Then, assuming, arguendo, that the ordinance was within the city's authority as a home rule municipality, the District Court considered City of Lafayette v. Louisiana Power & Light Co., 435 U. S. 389 (1978), and concluded that the Parker exemption was "wholly inapplicable," and that the city was therefore subject to antitrust liability. 485 F. Supp., at 1039.^[10] Petitioner's motion for a preliminary injunction was accordingly granted.

On appeal, a divided panel of the United States Court of Appeals for the Tenth Circuit reversed. 630 F. 2d 704 (1980). The majority, after examining Colorado law, rejected the District Court's conclusion that regulation of the cable television business was beyond the home rule authority *48 of the city. Id., at 707. The majority then addressed the question of the city's claimed Parker exemption. It distinguished the present case from City of Lafayette on the ground that, in contrast to the municipally operated revenueproducing utility companies at issue there, "no proprietary interest of the City is here involved." 630 F. 2d, at 708. After noting that the city's regulation "was the only control or active supervision exercised by state or local government, and . . . represented the only expression of policy as to the subject matter," id., at 707, the majority held that the city's actions therefore satisfied the criteria for a Parker exemption, 630 F. 2d, at 708.^[11] We granted certiorari, 450 U. S. 1039 (1981). We reverse.

A

Parker v. Brown, 317 U. S. 341 (1943), addressed the question whether the federal antitrust laws prohibited a State, in the exercise of its sovereign powers, from imposing certain anticompetitive restraints. These took the form of a "marketing program" adopted by the State of California for the 1940 raisin crop; that program prevented appellee from freely marketing his crop in interstate commerce. Parker noted that California's program "derived its authority . . . *49 from the legislative command of the state," id., at 350, and went on to hold that the program was therefore exempt, by virtue of the Sherman Act's own limitations, from antitrust attack:

"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." Id., at 350-351.

The availability of this exemption to a State's municipalities was the question presented in City of Lafayette, supra. In that case, petitioners were Louisiana cities empowered to own and operate electric utility systems both within and beyond their municipal limits. Respondent brought suit against petitioners under the Sherman Act, alleging that they had committed various antitrust offenses in the conduct of their utility systems, to the injury of respondent. Petitioners invoked the Parker doctrine as entitling them to dismissal of the suit. The District Court accepted this argument and dismissed. But the Court of Appeals for the Fifth Circuit reversed, holding that a "subordinate state governmental body is not ipso facto exempt from the operation of the antitrust laws," City of Lafayette v. Louisiana Power & Light Co., 532 F. 2d 431, 434 (1976) (footnote omitted), and directing the District Court on remand to examine "whether the state legislature contemplated a certain type of anticompetitive restraint," ibid.^[12]

*50 This Court affirmed. In doing so, a majority rejected at the outset petitioners' claim that, quite apart from Parker, "Congress never intended to subject local governments to the antitrust laws." 435 U. S., at 394. A plurality opinion for four Justices then addressed petitioners' argument that Parker, properly construed, extended to "all governmental entities, whether state agencies or subdivisions of a State,. . . simply by reason of their status as such." 435 U. S., at 408. The plurality opinion rejected this argument, after a discussion of Parker, Goldfarb v. Virginia State Bar, 421 U. S. 773 (1975), and Bates v. State Bar of Arizona, 433 U. S. 350 (1977).^[13] These precedents were construed as holding that the Parker exemption reflects the federalism principle that we are a Nation of States, a principle that makes no accommodation for sovereign subdivisions of States. The plurality opinion said:

"Cities are not themselves sovereign; they do not receive all the federal deference of the States that create them. Parker's limitation of the exemption to `official action directed by a state,' is consistent with the fact that the States' subdivisions generally have not been treated as *51 equivalents of the States themselves. In light of the serious economic dislocation which could result if cities were free to place their own parochial interests above the Nation's economic goals reflected in the antitrust laws, we are especially unwilling to presume that Congress intended to exclude anticompetitive municipal action from their reach." 435 U. S., at 412-413 (footnote and citations omitted).

The opinion emphasized, however, that the State as sovereign might sanction anticompetitive municipal activities and thereby immunize municipalities from antitrust liability. Under the plurality's standard, the Parker doctrine would shield from antitrust liability municipal conduct engaged in "pursuant to state policy to displace competition with regulation or monopoly public service." 435 U. S., at 413. This was simply a recognition that a State may frequently choose to effect its policies through the instrumentality of its cities and towns. It was stressed, however, that the "state policy" relied upon would have to be "clearly articulated and affirmatively expressed." Id., at 410. This standard has since been adopted by a majority of the Court. New Motor Vehicle Board of California v. Orrin W. Fox Co., 439 U. S. 96, 109 (1978); California Retail Liquor Dealers Assn. v. Midcal Aluminum, Inc., 445 U. S. 97, 105 (1980).^[14]

*52 B

Our precedents thus reveal that Boulder's moratorium ordinance cannot be 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, Orrin W. Fox Co., and Midcal. Boulder argues that these criteria are met by the direct delegation of powers to municipalities through the Home Rule Amendment to the Colorado Constitution. It contends that this delegation satisfies both the Parker and the City of Lafayette standards. We take up these arguments in turn.

(1)

Respondent city's Parker argument emphasizes that through the Home Rule Amendment the people of the State of Colorado have vested in the city of Boulder " `every power theretofore possessed by the legislature . . . in local and municipal affairs.' "^[15] The power thus possessed by Boulder's *53 City Council assertedly embraces the regulation of cable television, which is claimed to pose essentially local problems.^[16] Thus, it is suggested, the city's cable television moratorium ordinance is an "act of government" performed by the city acting as the State in local matters, which meets the "state action" criterion of Parker.^[17]

We reject this argument: it both misstates the letter of the law and misunderstands its spirit. The Parker state-action exemption reflects Congress' intention to embody in the Sherman Act the federalism principle that the States possess a significant measure of sovereignty under our Constitution. But this principle contains its own limitation: Ours is a "dual system of government," Parker, 317 U. S., at 351 (emphasis added), which has no place for sovereign cities. As this Court stated long ago, all sovereign authority "within the geographical limits of the United States" resides either with

"the Government of the United States, or [with] the States of the Union. There exist within the broad domain of sovereignty but these two. There may be cities, counties, and other organized bodies with limited legislative *54 functions, but they are all derived from, or exist in, subordination to one or the other of these." United States v. Kagama, 118 U. S. 375, 379 (1886) (emphasis added).

The dissent in the Court of Appeals correctly discerned this limitation upon the federalism principle: "We are a nation not of `city-states' but of States." 630 F. 2d, at 717. Parker itself took this view. When Parker examined Congress' intentions in enacting the antitrust laws, the opinion, as previously indicated, noted: "[N]othing in the language of the Sherman Act or in its history . . . suggests that its purpose was to restrain a state or its officers or agents from activities directed by its legislature. . . . [And] 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 (emphasis added). Thus Parker recognized Congress' intention to limit the state-action exemption based upon the federalism principle of limited state sovereignty. City of Lafayette, Orrin W. Fox Co., and Midcal reaffirmed both the vitality and the intrinsic limits of the Parker state-action doctrine. It was expressly recognized by the plurality opinion in City of Lafayette that municipalities "are not themselves sovereign," 435 U. S., at 412, and that accordingly they could partake of the Parker exemption only to the extent that they acted pursuant to a clearly articulated and affirmatively expressed state policy, 435 U. S., at 413. The Court adopted this view in Orrin W. Fox Co., 439 U. S., at 109, and Midcal, 445 U. S., at 105. We turn then to Boulder's contention that its actions were undertaken pursuant to a clearly articulated and affirmatively expressed state policy.

(2)

Boulder first argues that the requirement of "clear articulation and affirmative expression" is fulfilled by the Colorado Home Rule Amendment's "guarantee of local autonomy." It contends, quoting from City of Lafayette, 435 U. S., at 394, *55 415, that by this means Colorado has "comprehended within the powers granted" to Boulder the power to enact the challenged ordinance, and that Colorado has thereby "contemplated" Boulder's enactment of an anticompetitive regulatory program. Further, Boulder contends that it may be inferred, "from the authority given" to Boulder "to operate in a particular area" — here, the asserted home rule authority to regulate cable television — "that the legislature contemplated the kind of action complained of." (Emphasis supplied.) Boulder therefore concludes that the "adequate state mandate" required by City of Lafayette, supra, at 415, is present here.^[18]

But plainly the requirement of "clear articulation and affirmative expression" is not satisfied when the State's position is one of mere neutrality respecting the municipal actions challenged as anticompetitive. A State that allows its municipalities to do as they please can hardly be said to have "contemplated" the specific anticompetitive actions for which municipal liability is sought. Nor can those actions be truly described as "comprehended within the powers granted," since the term, "granted," necessarily implies an affirmative addressing of the subject by the State. The State did not do so here: The relationship of the State of Colorado to Boulder's moratorium ordinance is one of precise neutrality. As the majority in the Court of Appeals below acknowledged: "[W]e are here concerned with City action in the absence of any regulation whatever by the State of Colorado. Under these circumstances there is no interaction of state and local regulation. We have only the action or exercise of authority by the City." 630 F. 2d, at 707. Indeed, Boulder argues that *56 as to local matters regulated by a home rule city, the Colorado General Assembly is without power to act. Cf. City of Lafayette, supra, at 414, and n. 44. Thus in Boulder's view, it can pursue its course of regulating cable television competition, while another home rule city can choose to prescribe monopoly service, while still another can elect free-market competition: and all of these policies are equally "contemplated," and "comprehended within the powers granted." Acceptance of such a proposition — that the general grant of power to enact ordinances necessarily implies state authorization to enact specific anticompetitive ordinances — would wholly eviscerate the concepts of "clear articulation and affirmative expression" that our precedents require.

III

Respondents argue that denial of the Parker exemption in the present case will have serious adverse consequences for cities, and will unduly burden the federal courts. But this argument is simply an attack upon the wisdom of the longstanding congressional commitment to the policy of free markets and open competition embodied in the antitrust laws.^[19] Those laws, like other federal laws imposing civil or criminal sanctions upon "persons," of course apply to municipalities as well as to other corporate entities.^[20] Moreover, judicial enforcement *57 of Congress' will regarding the state-action exemption renders a State "no less able to allocate governmental power between itself and its political subdivisions. It means only that when the State itself has not directed or authorized an anticompetitive practice, the State's subdivisions in exercising their delegated power must obey the antitrust laws." City of Lafayette, 435 U. S., at 416. As was observed in that case:

"Today's decision does not threaten the legitimate exercise of governmental power, nor does it preclude municipal government from providing services on a monopoly basis. Parker and its progeny make clear that a State properly may . . . direct or authorize its instrumentalities to act in a way which, if it did not reflect state policy, would be inconsistent with the antitrust laws. . . . [A]ssuming that the municipality is authorized to provide a service on a monopoly basis, these limitations on municipal action will not hobble the execution of legitimate governmental programs." Id., at 416-417 (footnote omitted).

The judgment of the Court of Appeals is reversed, and the action is remanded for further proceedings consistent with this opinion.

It is so ordered.

JUSTICE WHITE took no part in the consideration or decision of this case.

*58 JUSTICE STEVENS, concurring.

The Court's opinion, which I have joined, explains why the city of Boulder is not entitled to an exemption from the antitrust laws. The dissenting opinion seems to assume that the Court's analysis of the exemption issue is tantamount to a holding that the antitrust laws have been violated. The assumption is not valid. The dissent's dire predictions about the consequences of the Court's holding should therefore be viewed with skepticism.^[1]

In City of Lafayette v. Louisiana Power & Light Co., 435 U. S. 389, we held that municipalities' activities as providers of services are not exempt from the Sherman Act. The reasons for denying an exemption to the city of Lafayette are equally applicable to the city of Boulder, even though Colorado is a home-rule State. We did not hold in City of Lafayette that the city had violated the antitrust laws. Moreover, that question is quite different from the question whether the city of Boulder violated the Sherman Act because the character of their respective activities differs. In both cases, the violation issue is separate and distinct from the exemption issue.

A brief reference to our decision in Cantor v. Detroit Edison Co., 428 U. S. 579, will identify the invalidity of the dissent's assumption. In that case, the Michigan Public Utility Commission had approved a tariff that required the Detroit Edison Co. to provide its customers free light bulbs. The company contended that its light bulb distribution program was therefore exempt from the antitrust laws on the authority of Parker v. Brown, 317 U. S. 341. See 428 U. S., at *59 592. The Court rejected the company's interpretation of Parker and held that the plaintiff could proceed with his antitrust attack against the company's program. We surely did not suggest that the members of the Michigan Public Utility Commission who had authorized the program under attack had thereby become parties to a violation of the Sherman Act. On the contrary, the plurality opinion reviewed the Parker case in great detail to emphasize the obvious difference between a charge that public officials have violated the Sherman Act and a charge that private parties have done so.^[2]

It would be premature at this stage of the litigation to comment on the question whether petitioner will be able to establish that respondents have violated the antitrust laws. The *60 answer to that question may depend on factual and legal issues that must and should be resolved in the first instance by the District Court. In accordance with my belief that "the Court should adhere to its settled policy of giving concrete meaning to the general language of the Sherman Act by a process of case-by-case adjudication of specific controversies," 428 U. S., at 603 (opinion of STEVENS, J.), I offer no gratuitous advice about the questions I think might be relevant. My only observation is that the violation issue is not nearly as simple as the dissenting opinion implies.

JUSTICE REHNQUIST, with whom THE CHIEF JUSTICE and JUSTICE O'CONNOR join, dissenting.

The Court's decision in this case is flawed in two serious respects, and will thereby impede, if not paralyze, local governments' efforts to enact ordinances and regulations aimed at protecting public health, safety, and welfare, for fear of subjecting the local government to liability under the Sherman Act, 15 U. S. C. § 1 et seq. First, the Court treats the issue in this case as whether a municipality is "exempt" from the Sherman Act under our decision in Parker v. Brown, 317 U. S. 341 (1943). The question addressed in Parker and in this case is not whether state and local governments are exempt from the Sherman Act, but whether statutes, ordinances, and regulations enacted as an act of government are pre-empted by the Sherman Act under the operation of the Supremacy Clause. Second, in holding that a municipality's ordinances can be "exempt" from antitrust scrutiny only if the enactment furthers or implements a "clearly articulated and affirmatively expressed state policy," ante, at 52, the Court treats a political subdivision of a State as an entity indistinguishable from any privately owned business. As I read the Court's opinion, a municipality may be said to violate the antitrust laws by enacting legislation in conflict with the Sherman Act, unless the legislation is enacted pursuant to an affirmative state policy to supplant competitive market forces in the area of the economy to be regulated.

*61 I

Pre-emption and exemption are fundamentally distinct concepts. Pre-emption, because it involves the Supremacy Clause, implicates our basic notions of federalism. Preemption analysis is invoked whenever the Court is called upon to examine "the interplay between the enactments of two different sovereigns — one federal and the other state." Handler, Antitrust — 1978, 78 Colum. L. Rev. 1363, 1379 (1978). We are confronted with questions under the Supremacy Clause when we are called upon to resolve a purported conflict between the enactments of the Federal Government and those of a state or local government, or where it is claimed that the Federal Government has occupied a particular field exclusively, so as to foreclose any state regulation. Where pre-emption is found, the state enactment must fall without any effort to accommodate the State's purposes or interests. Because pre-emption treads on the very sensitive area of federal-state relations, this Court is "reluctant to infer pre-emption," Exxon Corp. v. Governor of Maryland, 437 U. S. 117, 132 (1978), and the presumption is that preemption is not to be found absent the clear and manifest intention of Congress that the federal Act should supersede the police powers of the States. Ray v. Atlantic Richfield Co., 435 U. S. 151, 157 (1978).

In contrast, exemption involves the interplay between the enactments of a single sovereign — whether one enactment was intended by Congress to relieve a party from the necessity of complying with a prior enactment. See, e. g., National Broiler Marketing Assn. v. United States, 436 U. S. 816 (1978) (Sherman Act and Capper-Volstead Act); United States v. Philadelphia National Bank, 374 U. S. 321, 350-355 (1963) (Clayton Act and Bank Merger Act of 1960); Silver v. New York Stock Exchange, 373 U. S. 341, 357-361 (1963) (Sherman Act and Securities Exchange Act). Since the enactments of only one sovereign are involved, no problems of federalism are present. The court interpreting the *62 statute must simply attempt to ascertain congressional intent, whether the exemption is claimed to be express or implied. The presumptions utilized in exemption analysis are quite distinct from those applied in the pre-emption context. In examining exemption questions, "the proper approach . . . is an analysis which reconciles the operation of both statutory schemes with one another rather than holding one completely ousted." Silver v. New York Stock Exchange, supra, at 357.

With this distinction in mind, I think it quite clear that questions involving the so-called "state action" doctrine are more properly framed as being ones of pre-emption rather than exemption. Issues under the doctrine inevitably involve state and local regulation which, it is contended, are in conflict with the Sherman Act.

Our decision in Parker v. Brown, supra, was the genesis of the "state action" doctrine. That case involved a challenge to a program established pursuant to the California Agricultural Prorate Act, which sought to restrict competition in the State's raisin industry by limiting the producer's ability to distribute raisins through private channels. The program thus sought to maintain prices at a level higher than those maintained in an unregulated market. This Court assumed that the program would violate the Sherman Act were it "organized and made effective solely by virtue of a contract, combination or conspiracy of private persons, individual or corporate," and that "Congress could, in the exercise of its commerce power, prohibit a state from maintaining a stabilization program like the present because of its effect on interstate commerce." 317 U. S., at 350. In this regard, we noted that "[o]ccupation of a legislative field by Congress in the exercise of a granted power is a familiar example of its constitutional power to suspend state laws." Ibid. We then held, however, that "[w]e 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 *63 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." Id., at 350-351.

This is clearly the language of federal pre-emption under the Supremacy Clause. This Court decided in Parker that Congress did not intend the Sherman Act to override state legislation designed to regulate the economy. There was no language of "exemption," either express or implied, nor the usual incantation that "repeals by implication are disfavored." Instead, the Court held that state regulation of the economy is not necessarily pre-empted by the antitrust laws even if the same acts by purely private parties would constitute a violation of the Sherman Act. The Court recognized, however, that some state regulation is pre-empted by the Sherman Act, explaining that "a state does got give immunity to those who violate the Sherman Act by authorizing them to violate it, or by declaring that their action is lawful. . . ." Id., at 351.

Our two most recent Parker doctrine cases reveal most clearly that the "state action" doctrine is not an exemption at all, but instead a matter of federal pre-emption.

In New Motor Vehicle Bd. of California v. Orrin W. Fox Co.,
