delivered the opinion of the Court.
The question in this case is whether the National Labor Relations Act (NLRA), 29 U. S. C. §151 et seq., pre-empts a Wisconsin statute debarring certain repeat violators of the Act from doing business with the State. We hold that it does.
I
Wisconsin has directed its Department of Industry, Labor and Human Relations to maintain a list of every person or firm found by judicially enforced orders of the National Labor Relations Board to have violated the NLRA in three separate cases within a 5-year period. See Wis. Stat. § 101.245 (1983-1984). 1 State procurement agents are statu *284 torily forbidden to purchase “any product known to be manufactured or sold by any person or firm included on the list of labor law violators.” §16.75(8). 2 A name remains on the violators’ list for three years. § 101.245(4).
*285 Appellee Gould Inc. is a Delaware corporation with its principal place of business in Illinois. In 1982, Wisconsin placed Gould on its list of labor law violators following the judicial enforcement of four Board orders against various divisions of the company, none of which was located in Wisconsin and none of which Gould still owned at the time of its debarment. The State informed Gould that it would enter into no new contract with the company until 1985. The State also announced that it would continue its current contracts with Gould only as long as necessary to avoid contractual penalties, and that while Gould was on the list the State would not purchase products containing components produced by the company. At the time, Gould held state contracts worth over $10,000, and had outstanding bids for additional contracts in excess of $10,000.
Gould filed this action for injunctive and declaratory relief, arguing that the Wisconsin debarment scheme was preempted by the NLRA and violated the Due Process and Equal Protection Clauses of the Fourteenth Amendment.

The United States District Court for the Western District of Wisconsin granted Gould summary judgment on the preemption claim, and did not reach the arguments pertaining to the Fourteenth Amendment.
II
It is by now a commonplace that in passing the NLRA Congress largely displaced state regulation of industrial relations. Although some controversy continues over the Act’s pre-emptive scope, certain principles are reasonably settled. Central among them is the general rule set forth in
San Diego Building Trades Council
v.
Garmon,
*287
Consequently, there can be little doubt that the NLRA would prevent Wisconsin from forbidding
private parties
within the State to do business with repeat labor law violators. Like civil damages for picketing, which the Court refused to allow in
Garmon,
a prohibition against in-state private contracts would interfere with Congress’ “integrated scheme of regulation” by adding a remedy to those prescribed by the NLRA.
Wisconsin does not assert that it could bar its residents from doing business with repeat violators of the NLRA. It contends, however, that the statutory scheme invoked against Gould escapes pre-emption because it is an exercise of the State’s spending power rather than its regulatory power. But that seems to us a distinction without a difference, at least in this case, because on its face the debarment statute serves plainly as a means of enforcing the NLRA. The State concedes, as we think it must, that the point of the statute is to deter labor law violations and to reward “fidelity to the law.” Tr. of Oral Arg. 4, 6; Brief for Defendants in Support of Motion for Summary Judgment in No. 83-C-1045, (WD Wis.), p. 18. No other purpose could credibly be ascribed, given the rigid and undiscriminating manner in which the statute operates: firms adjudged to have violated the *288 NLRA three times are automatically deprived of the opportunity to compete for the State’s business. 5
Because Wisconsin’s debarment law functions unambiguously as a supplemental sanction for violations of the NLRA, it conflicts with the Board’s comprehensive regulation of industrial relations in precisely the same way as would a state statute preventing repeat labor law violators from doing any business with private parties within the State. Moreover, if Wisconsin’s debarment law is valid, nothing prevents other States from taking similar action against labor law violators. Indeed, at least four other States already have passed legislation disqualifying repeat or continuing offenders of the NLRA from competing for state contracts. 6 Each additional statute incrementally diminishes the Board’s control over enforcement of the NLRA and thus further detracts *289 from the “integrated scheme of regulation” created by Congress.
That Wisconsin has chosen to use its spending power rather than its police power does not significantly lessen the inherent potential for conflict when “two separate remedies are brought to bear on the same activity,”
Garner,
Ill
Wisconsin notes correctly that state action in the nature of “market participation” is not subject to the restrictions placed on state regulatory power by the Commerce Clause. See
White
v.
Massachusetts Council of Constr. Employers, Inc.,
In any event, the “market participant” doctrine reflects the particular concerns underlying the Commerce Clause, not any general notion regarding the necessary extent of state power in areas where Congress has acted. In addition to authorizing congressional action, the Commerce Clause limits state action in the absence of federal approval. The Clause restricts “state taxes and regulatory measures impeding free private trade in the national marketplace,” but “[t]here is no indication of a constitutional plan to limit the ability of the States themselves to operate freely in the free market.”
Reeves,
Nothing in the NLRA, of course, prevents private purchasers from boycotting labor law violators. But government occupies a unique position of power in our society, and its conduct, regardless of form, is rightly subject to special restraints. Outside the area of Commerce Clause jurisprudence, it is far from unusual for federal law to prohibit States from making spending decisions in ways that are permissible for private parties. See,
e. g., Elrod
v.
Burns,
*291
We do not say that state purchasing decisions may never be influenced by labor considerations, any more than the NLRA prevents state regulatory power from ever touching on matters of industrial relations. Doubtless some state spending policies, like some exercises of the police power, address conduct that is of such “peripheral concern” to the NLRA, or that implicates “interests so deeply rooted in local feeling and responsibility,” that pre-emption should not be inferred.
Garmon,
The judgment of the Court of Appeals is affirmed.
It is so ordered.
Notes
Section 101.245 provides in relevant part:
“(1) The department [of industry, labor and human relations] shall maintain a list of persons or firms that have been found by the national labor relations board, and by 3 different final decisions of a federal court within a *284 5-year period as determined under sub. (lm), if the 3 final decisions involved a cumulative finding of at least three separate violations, to have violated the national labor relations act, 29 U. S. C. 151 et seq., and of persons or firms that have been found to be in contempt of court for failure to correct a violation of the national labor relations act on 3 or more occasions by a court within a 5-year period as determined under sub. (lm) if the 3 contempt findings involved a cumulative total of at least 3 different violations.
“(lm) On or before July 1 of each year the department shall compile the list required under sub. (1) based upon the 5-year period which ended on September 30 of the year preceding.
“(2) This list may be compiled from the records of the national labor relations board.
“(3) Whenever a new name is added to this list the department shall send the name to the department of administration for actions as provided in s. 16.75(8).
“(4) A name shall remain on the list for 3 years.”
The statute was enacted as 1979 Wis. Laws, ch. 340, § 3. It became effective May 21, 1980.
Section 16.75(8) provides in relevant part:
“The department [of administration] shall not purchase any product known to be manufactured or sold by any person or firm included on the list of labor law violators compiled by the department of industry, labor and human relations under s. 101.245. The secretary may waive this subsection if maintenance, repair or operating supplies are required to maintain systems or equipment which were purchased by the state from a person or firm included on the list prior to the date of inclusion on the list, or if the secretary finds that there exists an emergency which threatens the public health, safety or welfare and a waiver is necessary to meet the emergency.”
We are advised that the statutory ban applies only to purchases by the State and not to purchasing decisions of counties, municipalities, or other political subdivisions of the State. Tr. of Oral Arg. 4.
In addition to disqualifying repeat violators of the NLRA, Wisconsin provides statutory preferences to bids from Wisconsin companies, minority businesses, employers of disabled workers, and prison industries. See Wis. Stat. §§ 16.75(1)(a), (3m)(b), (3s)(a), and (3t)(c) (1983-1984).
The original complaint also sought monetary damages, but Gould apparently abandoned this request in its motion and briefs for summary judgment. See
Although Gould’s debarment was scheduled to end in 1985, Wisconsin does not contend that the case is moot. At a minimum, the problem presented is “capable of repetition, yet evading review.”
E. g., Dunn
v.
Blumstein,
The complaint named as defendants three state agencies, including the Department of Industry, Labor and Human Relations, and four state officials. The District Court dismissed the agency defendants under the Eleventh Amendment but, pursuant to
Ex parte Young,
The conflict between the challenged debarment statute and the NLRA is made all the more obvious by the essentially punitive rather than corrective nature of Wisconsin’s supplemental remedy. The regulatory scheme established for labor relations by Congress is “essentially remedial,” and the Board is not generally authorized to impose penalties solely for the purpose of deterrence or retribution.
