Justice O’Connor
delivered the opinion of the Court.
In 1976, the citizens of New Jersey amended their State Constitution to permit the legislative authorization of casino [494]*494gambling within the municipality of Atlantic City.1 Determined to prevent the infiltration of organized crime into its nascent casino industry and to assure public trust in the industry’s integrity, the New Jersey Legislature enacted the Casino Control Act (Act), N. J. Stat. Ann. § 5:12-1 et seq. (West Supp. 1983-1984), which provides for the comprehensive regulation of casino gambling, including the regulation of unions representing industry employees. Sections 86 and 93 of the Act specifically impose certain qualification criteria on officials of labor organizations representing casino industry employees. Those labor organizations with officials found not to meet these standards may be prohibited from receiving dues from casino industry employees and prohibited from administering pension and welfare funds. The principal question presented by these cases is whether the National Labor Relations Act (NLRA), as amended, 29 U. S. C. § 141 et seq., precludes New Jersey from imposing these criteria on those whom casino industry employees may select as officials of their bargaining representatives. We hold that it does not.
I
A
The advent of casino gambling in New Jersey was heralded with great expectations for the economic revitalization of the [495]*495Atlantic City region, but with equally great fears for the potential for infiltration by organized crime. The state legislature conducted extensive hearings and, in cooperation with the Governor, commissioned numerous studies on how best to prevent infiltration by organized crime into the casino industry.2 These studies confirmed the fact that the vast amount of money that flows daily through a casino operation and the large number of unrecorded transactions make the industry a particularly attractive and vulnerable target for organized crime. The New Jersey Commission of Investigation (NJCI), for example, found that there was a “well-organized highly functional organized crime network in [New Jersey]” which had become more interested in investing funds in legitimate enterprises.3 The NJCI feared that such an incursion by organized crime into the Atlantic City casinos might also be accompanied by extortion, loansharking, commercial bribery, and tax and antitrust violations. It was on the basis of these hearings and empirical studies that New Jersey finally adopted the Act, a comprehensive statutory scheme that authorizes casino gambling and establishes a rigorous system of regulation for the entire casino industry.
In order to promote “public confidence and trust in the credibility and integrity of the regulatory process and of [496]*496casino operations,” the Act “extend[s] strict State regulation to all persons, locations, practices and associations related to the operation of licensed casino enterprises and all related service industries.” N. J. Stat. Ann. § 5:12 — 1(b)(6) (West Supp. 1983-1984). The Casino Control Commission (Commission), an independent administrative body, possesses broad regulatory authority over the casinos and other related industries, §§5:12-63 to 5:12-75. The Division of Gaming Enforcement (Division), a part of the Attorney General’s Office, is charged with the responsibility for investigating license and permit applicants and for prosecuting violators of the Act, §§5:12-76 to 5:12-79.
The Act imposes strict licensing requirements on any business seeking to own and operate a casino hotel, §§5:12-84(a)-(c); on suppliers of goods and services to casino hotels, §§5:12-12, 5:12-92; on all supervisory employees involved in casino operations, §§5:12-9, 5:12-89; and on all employees with access to the casino floor, §§5:12-7, 5:12-90. The Act requires registration, rather than licensing, for employees of casino hotels. Casino hotel employees include those performing “service or custodial duties not directly related to operations of the casino, including, without limitation, bartenders, waiters, waitresses, maintenance personnel, kitchen staff, but whose employment duties do not require or authorize access to the casino.” §5:12-8. Most relevant to this litigation, § 93(a) of the Act also requires labor organizations that represent or seek to represent persons employed in casinos or casino hotels to register annually with the Commission, §5:12-93(a).
All those entities and persons required to be licensed or registered are subject to the disqualification criteria set forth in § 86 of the Act. Section 86 specifically lists criteria for the disqualification of casino licensees. The Commission is authorized to revoke, suspend, limit, or otherwise restrict the registration of any casino hotel employees who would be disqualified for a casino license. N. J. Stat. Ann. §§ 5:12-86, 5:12-91(b) (West Supp. 1983-1984). All industries offering [497]*497goods or services to the casinos are also subject to the disqualification criteria of § 86. § 5:12-92.
Section 93(b) directly subjects registered labor organizations to the §86 disqualification criteria and imposes two express penalties for noncompliance:
“No labor organization, union or affiliate registered or required to be registered pursuant to this section and representing or seeking to represent employees licensed or registered under this act may receive any dues from any employee licensed or registered under this act and employed by a casino licensee or its agent, or administer any pension or welfare funds, if any officer, agent, or principal employee of the labor organization, union or affiliate is disqualified in accordance with the criteria contained in section 86 of this act. The commission may for the purposes of this subsection waive any disqualification criterion consistent with the public policy of this act and upon a finding that the interests of justice so require.”
The disqualification criteria referred to in §86 include convictions for a list of enumerated offenses or “any other offense which indicates that licensure of the applicant would be inimical to the policy of this act and to casino operations.” N. J. Stat. Ann. § 5:12 — 86(c)(4) (West Supp. 1983-1984). Disqualification may also result if an individual is identified “as a career offender or a member of a career offender cartel or an associate of a career offender or career offender cartel in such a manner which creates a reasonable belief that the association is of such a nature as to be inimical to the policy of this act and to gaming operations.” § 5:12-86(f ).4
[498]*498B
Appellee Hotel and Restaurant Employees and Bartenders International Union Local 54 (Local 54) is an unincorporated labor organization within the meaning of § 2(5) of the NLRA, 29 U. S. C. § 152(5). Local 54 represents in collective bargaining approximately 12,000 employees, 8,000 of whom are employed in casino hotels in Atlantic City. All of Local 54’s casino hotel employees work in traditional hotel and restaurant service-related positions; none are employed in direct gambling operations. Appellee Frank Gerace is the president of Local 54.
In 1978, Local 54 began filing with the Commission the annual registration statement required by § 93(a) of the Act. Following a lengthy investigation, the Division in 1981 reported to the Commission that, in its view, Local 54's President Gerace, Secretary-Treasurer Robert Lumio, and Grievance Manager Frank Materio were disqualified under the criteria of §86. Pursuant.to that section, the Commission scheduled a hearing on the Division’s allegations. When Local 54 raised objections to the constitutionality of §86 and §93, the Commission ruled that it lacked the authority to consider such challenges to its enabling statute. In response, appellees filed a complaint in District Court,5 seeking declaratory and injunctive relief on the grounds that §86 and § 93 impermissibly regulate areas which are preempted by the NLRA, the Employee Retirement Income Security Act (ERISA), 29 U. S. C. §1001 et seq., and the Labor-Management Reporting and Disclosure Act of 1959 [499]*499(LMRDA), 29 U. S. C. §401 et seq., and that § 86(f) violates the Constitution because it is both overbroad and vague. Appellees also filed a motion for preliminary injunctive relief alleging irreparable injury from being forced to participate in further Commission proceedings.
After a hearing, the District Court denied the motion for a preliminary injunction, concluding that appellees were unlikely to succeed on the merits of their claims.6 536 F. Supp. 317 (NJ 1982). Since no preliminary injunction was entered, the Commission went forward with its disqualification hearing. The Commission concluded that Gerace and Materio were disqualified under § 86(f) because they were associated with members of organized crime in a manner inimical to the policy of the Act and to gaming operations. Local 54’s Business Agent, Karlos LaSane, was also held disqualified under § 86(c) because he had been convicted in 1973 of extortion from persons doing business with Atlantic City while he was a City Commissioner.7 On the basis of its findings, the Commission ordered that these individuals be removed as officers, agents, or principal employees of Local 54, failing which Local 54 would be barred from collecting dues from any of its members who were licensed or registered employees under the Act. See App. to Juris. Statements 206a-207a. The Commission later issued a supplemental decision, determining that the prohibition against dues collection would suffice to effectuate the removal of the three union officials and that it was therefore unnecessary to invoke the additional sanction of prohibiting the disqualified officials from administering pension and welfare funds. Id., at 208a-215a.
[500]*500Subsequent to the Commission’s decision, a divided panel of the United States Court of Appeals for the Third Circuit issued a ruling concluding that the District Court had erred in refusing to grant the preliminary injunction. 709 F. 2d 815 (1983). Reaching the merits of the underlying complaint, the court decided that § 93 of the Act is pre-empted by § 7 of the NLRA insofar as it empowers the Commission to disqualify elected union officials and is pre-empted by ERISA insofar as it empowers the Commission to prohibit administration of pension and welfare funds.8
We noted probable jurisdiction, and consolidated the separate appeals of the Commission and the Division to consider the pre-emption issue, 464 U. S. 990 (1983).9
II
When federal pre-emption is invoked under the directive of the Supremacy Clause, it falls to this Court to examine the presumed intent of Congress. See Fidelity Federal Savings & Loan Assn. v. De la Cuesta, 458 U. S. 141, 152-153 (1982). [501]*501Our task is quite simple if, in the federal enactment, Congress has explicitly mandated the pre-emption of state law, see Shaw v. Delta Air Lines, Inc., 463 U. S. 85, 95-100 (1983), or has adequately indicated an intent to occupy the field of regulation, thereby displacing all state laws on the same subject, Rice v. Santa Fe Elevator Corp., 331 U. S. 218, 230 (1947). Even in the absence of such express language or implied congressional intent to occupy the field, we may nevertheless find state law to be displaced to the extent that it actually conflicts with federal law. Such actual conflict between state and federal law exists when “compliance with both federal and state regulations is a physical impossibility,” Florida Lime & Avocado Growers, Inc. v. Paul, 373 U. S. 132, 142-143 (1963), or when state law “stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress,” Hines v. Davidowitz, 312 U. S. 52, 67 (1941). See Michigan Canners & Freezers Assn., Inc. v. Agricultural Marketing and Bargaining Board, 467 U. S. 461, 469 (1984); Fidelity Federal Savings & Loan Assn. v. De la Cuesta, supra.
These pre-emption principles are no less applicable in the field of labor law. Section 7 of the NLRA, 49 Stat. 452, as amended, 29 U. S. C. §157, the provision involved in this case, neither contains explicit pre-emptive language nor otherwise indicates a congressional intent to usurp the entire field of labor-management relations. See New York Telephone Co. v. New York State Dept. of Labor, 440 U. S. 519, 540 (1979); Garner v. Teamsters, 346 U. S. 485, 488 (1953) (“The national. . . Act. . . leaves much to the states, though Congress has refrained from telling us how much”). The Court has, however, frequently applied traditional preemption principles to find state law barred on the basis of an actual conflict with §7. If employee conduct is protected under § 7, then state law which interferes with the exercise of these federally protected rights creates an actual conflict and is pre-empted by direct operation of the Supremacy Clause. [502]*502See, e. g., Nash v. Florida Industrial Comm’n, 389 U. S. 235, 239-240 (1967) (invalidating state unemployment compensation law); Bus Employees v. Missouri, 374 U. S. 74, 81-82 (1963) (striking down state statute prohibiting peaceful strikes against public utilities); Bus Employees v. Wisconsin Board, 340 U. S. 383, 394 (1951) (same); Automobile Workers v. O’Brien, 339 U. S. 454, 458-459 (1950) (invalidating state “strike-vote” legislation).
Appellants argue that the appropriate framework for preemption analysis in these cases is the balancing test applied to those state laws which fall within the so-called “local interests” exception to the pre-emption doctrine first set forth in San Diego Building Trades Council v. Garmon, 359 U. S. 236, 243-244 (1959). They contend that because New Jersey’s interest in crime control is “so deeply rooted in local feeling and responsibility,” ibid., the Act may yet be sustained as long as the magnitude of the State’s interest in the enactment outweighs the resulting substantive interference with federally protected rights. See Operating Engineers v. Jones, 460 U. S. 669, 683 (1983). This argument, however, confuses pre-emption which is based on actual federal protection of the conduct at issue from that which is based on the primary jurisdiction of the National Labor Relations Board (NLRB). See, e. g., Railroad Trainmen v. Terminal Co., 394 U. S. 369, 383, n. 19 (1969). In the latter situation, a presumption of federal pre-emption applies even when the state law regulates conduct only arguably protected by federal law. Such a pre-emption rule avoids the potential for jurisdictional conflict between state courts or agencies and the NLRB by ensuring that primary responsibility for interpreting and applying this body of labor law remains with the NLRB. See Motor Coach Employees v. Lockridge, 403 U. S. 274, 286-289 (1971); San Diego Building Trades Council v. Garmon, supra, at 244-245. This presumption of federal pre-emption, based on the primary jurisdiction rationale, properly admits to exception when unusually “deeply rooted” [503]*503local interests are at stake. In such cases, appropriate consideration for the vitality of our federal system and for a rational allocation of functions belies any easy inference that Congress intended to deprive the States of their ability to retain jurisdiction over such matters. We have, therefore, refrained from finding that the NLRA pre-empts state court jurisdiction over state breach of contract actions by strike replacements, Belknap, Inc. v. Hale, 463 U. S. 491 (1983), state trespass actions, Sears, Roebuck & Co. v. Carpenters, 436 U. S. 180 (1978), or state tort remedies for intentional infliction of emotional distress, Farmer v. Carpenters, 430 U. S. 290 (1977).
If the state law regulates conduct that is actually protected by federal law, however, pre-emption follows not as a matter of protecting primary jurisdiction, but as a matter of substantive right. Where, as here, the issue is one of an asserted substantive conflict with a federal enactment, then “[t]he relative importance to the State of its own law is not material ... for the Framers of our Constitution provided that the federal law must prevail.” Free v. Bland, 369 U. S. 663, 666 (1962). We turn, therefore, to consider whether New Jersey’s Act actually conflicts with the casino industry employees’ § 7 rights.
Ill
Section 7 guarantees to employees various rights, among them the right “to bargain collectively through representatives of their own choosing.” 29 U. S. C. §157. In a straightforward analysis, the Court of Appeals found that this express right of employees to choose their collective-bargaining representatives encompasses an unqualified right to choose the officials of these representatives. Because § 93(b) of the Act precludes casino industry employees from selecting as union officials individuals who do not meet the §86 disqualification criteria, the Court of Appeals determined that this provision clearly and directly conflicts with [504]*504§ 7 and, under traditional pre-emption analysis, must be held pre-empted.
The Court of Appeals relied heavily on this Court’s decision in Hill v. Florida ex rel. Watson, 325 U. S. 538 (1945), as support for the threshold proposition that § 7 confers an unfettered right on employees to choose the officials of their own bargaining representatives. Hill involved a Florida statute that provided for state licensing of union business agents and prohibited the licensing of individuals who had not been citizens for more than 10 years, who had been convicted of a felony, or who were not of “good moral character.” The statute also required the unions to file annual reports. Pursuant to this law, the Florida Attorney General obtained injunctions against a union and its business agent, restraining them from functioning until they had complied with the statute.
On review, the Court found that Florida’s statute as applied conflicted with § 7, explaining:
“The declared purpose of the Wagner Act, as shown in its first section, is to encourage collective bargaining, and to protect the ‘full freedom’ of workers in the selection of bargaining representatives of their own choice. To this end Congress made it illegal for an employer to interfere with, restrain or coerce employees in selecting their representatives. Congress attached no conditions whatsoever to their freedom of choice in this respect. Their own best judgment, not that of someone else, was to be their guide. ‘Full freedom’ to choose an agent means freedom to pass upon that agent’s qualifications.” 325 U. S., at 541.
The decision in Hill does not control the present cases, however, because Congress has, in our view, subsequently disclaimed any intent to pre-empt all state regulation which touches upon the specific right of employees to decide which individuals will serve as officials of their bargaining representatives. As originally enacted, and as interpreted by the [505]*505Court in Hill, § 7 imposed no restrictions whatsoever on employees’ freedom to choose the officials of their bargaining representatives. In 1959, however, Congress enacted the Labor-Management Reporting and Disclosure Act (LMRDA), designed in large part to address the growing problems of racketeering, crime, and corruption in the labor movement. See S. Rep. No. 187, 86th Cong., 1st Sess., 12-16 (1959); H. R. Rep. No. 741, 86th Cong., 1st Sess., 9-12 (1959). Title V of LMRDA imposes various restrictions on labor union officials and defines certain qualifications for them. Specifically, 29 U. S. C. § 504(a) provides in pertinent part:
“No person. . . who has been convicted of, or served any part of a prison term resulting from his conviction of [a series of enumerated crimes] shall serve ... as an officer, director, trustee, member of any executive board or similar governing body, business agent, manager, organizer ... of any labor organization ... for five years after such conviction or after the end of such imprisonment . . . .”
By enacting § 504(a), Congress has unmistakably indicated that the right of employees to select the officers of their bargaining representatives is not absolute and necessarily admits of some exception. Of course, a strong counterargument can be made that Congress intended § 504(a) to be the very measure of the exception, thereby cutting back on the pre-emptive effect of § 7 only to that extent and no more. Although this is certainly a conceivable reading of congressional intent, we are, however, not persuaded by it.
As the Court has already recognized, another provision of LMRDA, § 603(a),10 is “an express disclaimer of pre-emption [506]*506of state laws regulating the responsibilities of union officials, except where such pre-emption is expressly provided . . . De Veau v. Braisted, 363 U. S. 144, 157 (1960) (plurality opinion); see also id., at 160-161 (Brennan, J., concurring in judgment) (LMRDA “explicitly provides that it shall not displace such legislation of the States”)-11 In affirmatively preserving the operation of state laws, § 603(a) indicates that Congress necessarily intended to preserve some room for state action concerning the responsibilities and qualifications of union officials. Moreover, §504 itself makes clear that Congress did not seek to impose a uniform federal standard on those who may serve as union officials. An individual is disqualified from holding office for five years under § 504 only if he has been convicted of certain state law crimes. His eligibility for union office may be restored earlier depending on the various state laws providing for the restoration of citizen rights to convicted felons. See 104 Cong. Rec. 10991-10994 (1958) (remarks of Sen. McNamara). Thus, the federal law’s disqualification criteria themselves are premised on state laws which of course vary throughout the Nation. Finally, our conclusion that Congress might not view such state regulation as necessarily interfering with national labor policy is buttressed by consideration of the concerns that led Congress to enact LMRDA in the first place. Congress was prompted to take action in large part because the governmental machinery was not “effective in policing specific abuses at the local level” and in “stamping] out crime and corruption [in [507]*507unions].” S. Rep. No. 187, supra, at 6. Consistent with this overarching legislative purpose, we can more readily presume that Congress would allow a State to adopt different and more stringent qualification requirements for union officials to effectuate this important goal.
In De Veau v. Braisted, supra, this Court first squarely confronted the issue of post -Hill congressional intent in the context of a challenge to §8 of the New York Waterfront Commission Act. The New York statute prohibited any labor organization representing waterfront employees from collecting dues if any of its officers or agents had been convicted of a felony and had not subsequently been pardoned or cleared by the parole board. The statute had been enacted in furtherance of an interstate compact betweeen New York and New Jersey, establishing a bistate commission intended to combat crime and corruption on the States’ mutual waterfront. The compact had been expressly approved by Congress pursuant to Art. I, § 10, of the Federal Constitution. The argument urged upon the Court was that the New York statute was pre-empted by §7 of the NLRA as conflicting with Hill’s guarantee of “complete freedom of choice in the selection of [waterfront employees’] representatives.” 363 U. S., at 152. In an opinion for a four-justice plurality, Justice Frankfurter rejected this pre-emption argument and upheld the challenged statute.
The plurality opinion began by noting that the NLRA “does not exclude every state policy that may in fact restrict the complete freedom of a group of employees to designate 'representatives of their own choosing.’” Ibid. The plurality reasoned:
“It would misconceive the constitutional doctrine of preemption — of the exclusion because of federal regulation of what otherwise is conceded state power — to decide this case mechanically on an absolute concept of free choice of representatives on the part of employees, heed[508]*508less of the light that Congress has shed for our guidance. The relevant question is whether we may fairly infer a congressional purpose incompatible with the very narrow and historically explained restrictions upon the choice of a bargaining representative embodied in §8 of the New York Waterfront Commission Act. Would Congress, with a lively regard for its own federal labor policy, find in this state enactment a true, real frustration, however dialetically plausible, of that policy?” Id., at 153 (emphasis added).
After thus framing the inquiry, the plurality concluded that the Court need not in fact “imaginatively summon” a hypothetical congressional response since, in light of Congress’ express approval of the compact, federal pre-emption could not be found. Ibid.
DeVeau’s direct relevance for these cases lies less in its approach to determining § 7’s pre-emptive scope than in its focus on the indicia of congressional intent that can be garnered from Congress’ approval of the compact. At congressional hearings, labor union officials testified against the compact’s ratification on the specific ground that the New York statute conflicted with federal labor policy and that approval of the compact would therefore appear to sanction all such state restrictions. See 363 U. S., at 151 (citing to testimony of International Longshoremen’s Association). In approving the compact over such objections, Congress apparently concluded that, at least where the States were confronted with the “public evils”12 of “crime, corruption, and racketeering,”13 more stringent state regulation of the qualifications of union officials was not incompatible with the national labor policy as embodied in §7.14
[509]*509In short, given Congress’ intent as expressed in its enactment of LMRDA and its approval of the bistate compact at issue in De Veau, it can no longer be maintained that § 7 necessarily and obviously conflicts with every state regulation that may restrict the right of employees to select certain individuals to serve as the officials of their bargaining representatives. Nor can we find that New Jersey’s imposition of its disqualification criteria in any way “stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress.” Hines v. Davidowitz, 312 U. S., at 67. In its enactment of LMRDA and its awareness of New York’s comparable restrictions when approving the bistate compact, Congress has at least indicated both that employees do not have an unqualified right to choose their union officials and that certain state disqualification requirements are compatible with § 7. This is particularly true in the case of New Jersey’s disqualification criteria, the purpose of which is identical to that which motivated those New York restrictions implicitly approved by Congress: Both statutes form part of comprehensive programs designed to “vindicate a legitimate and compelling state interest, namely, the interest in combatting local crime infesting a particular industry.” DeVeau v. Braisted, supra, at 156. In the absence of a more specific congressional intent to the contrary, we therefore conclude that New Jersey’s regulation of the qualifications of casino industry union officials does not actually conflict with § 7 and so is not pre-empted by the NLR A.
We emphasize that this conclusion does not implicate the employees’ express § 7 right to select a particular labor union as their collective-bargaining representative, but only their subsidiary right to select the officials of that union organization. While the Court in Hill v. Florida ex rel. Watson, [510]*510apparently assumed that the two rights were undifferentiated and equally protected, our reading of subsequent legislative action indicates that Congress has since distinguished between the two and has accorded less than absolute protection to the employees’ right to choose their union officials. In this litigation, the casino industry employees’ freedom in the first instance to select Local 54 to represent them in collective bargaining is simply not affected by the qualification criteria of New Jersey’s Act.
1 — 1 <J
Although the NLRA does not preclude § 93(b)’s imposition of qualification standards on casino industry union officials,15 also at issue is the separate validity of that provision’s dues collection ban imposed by the Commission to effect the removal of these disqualified persons from their union positions. As in Hill v. Florida ex rel. Watson, a sanction for noneom-pliance with an otherwise valid state regulation must, for pre-emption purposes, be assessed independently in terms of its potential conflict with the federal enactment. The Court in Hill concluded that Florida’s filing requirement, while itself unobjectionable, could not be enforced by an injunction against the union’s “functioning as a labor union” without contravening the NLRA. See 325 U. S., at 543. Appellees vigorously contend that imposition of the § 93(b)’s dues collection sanction will similarly prohibit Local 54 from functioning [511]*511as the employees’ bargaining representative, thereby directly abridging the employees’ separate § 7 rights to organize and bargain collectively. According to affidavits submitted in the District Court, 85% of Local 54’s monthly income comes from membership dues paid by casino hotel employees. Without these payments, Local 54 claims that it could no longer process employee grievances, administer collective-bargaining agreements, bargain for new agreements, organize the unorganized, or perform the other responsibilities of a collective-bargaining agent. See Brief for Appellees 23-24, and n. 11.
Unfortunately, because of the procedural posture of this litigation, we cannot decide this issue. Appellees’ factual allegations were never addressed by the District Court and the Court of Appeals. We are thus confronted with a situation comparable to that presented in Alabama State Federation of Labor v. McAdory, 325 U. S. 450 (1945), in which the Court declined to decide whether the NLRA pre-empted a state filing requirement for unions because the statute had not been “construed to operate ... by its penal sanctions . . . to prevent [the unions]. . . from functioning within the state for non-compliance ...” Id., at 466. We follow the same course here, and remand so that the District Court can make the requisite findings of fact to determine whether imposition of the dues collection ban will so incapacitate Local 54 as to prevent it from performing its functions as the employees’ chosen collective-bargaining agent.
We observe that even a finding that § 7 prohibits imposition of the dues collection sanction need not imply that New Jersey’s disqualification standards are not otherwise enforceable by the Commission. The Act, for example, apparently grants broad powers to the Commission to impose sanctions directly on disqualified persons and to limit or restrict a labor organization’s registration. See N. J. Stat. Ann. §5:12-64 (West Supp. 1983-1984). The Act also provides that the Commission “may exercise any proper power or authority [512]*512necessary to perform the duties assigned to it by law,” and that “no specific enumeration of powers in this act shall be read to limit the authority of the commission to administer this act.” §5:12-75. The Commission itself has implicitly construed the Act as granting it the statutory authority to fashion different and less severe sanctions than those expressly enumerated in § 93(b). See App. to Juris. Statements 206a; 536 F. Supp., at 330. If the Commission has correctly interpreted state law, an issue we of course do not decide, it could then enforce § 93(b)’s disqualification criteria by numerous other means.
Finally, we also decline to reach the validity of §93(b)’s second sanction — prohibition of a union’s administration of its pension or welfare funds — despite the Court of Appeals’ unanimous holding that the sanction is expressly pre-empted by § 514(a) of ERISA, 29 U. S. C. § 1144(a). In its supplemental decision, the Commission asserted its general authority to impose this sanction on Local 54, but, exercising its broad discretion, chose not to do so at that time. That decision rested both on the Commission’s assumption that the dues collection sanction alone would suffice to ensure Local 54’s compliance with the disqualification order and on its determination that it lacked adequate information as to whether Local 54 in fact administers pension and welfare funds within the meaning of § 93(b) as well as to the manner in which such a prohibition might impact the membership. See App. to Juris. Statements 214a; supra, at 499. Because the Commission never imposed this sanction on Local 54, we are presented with no concrete application of state law. The issue is hence not ripe for review, and the Court of Appeals’ holding that the federal ERISA pre-empts this sanction must therefore be vacated. See, e. g., Longshoremen v. Boyd, 347 U. S. 222, 224 (1954).
V
We find that § 93 of New Jersey’s Act is not pre-empted by § 7 of the NLRA to the extent that it imposes certain limi[513]*513tations on whom casino industry employees may choose to serve as officials of their bargaining representatives. On remand, the District Court should determine whether imposition of § 93(b)’s sanction of prohibiting the collection of dues from casino industry employees will effectively prevent the union from performing its statutory functions as bargaining representative for its members. The judgment of the Court of Appeals is therefore vacated, and the cases are remanded to the Court of Appeals with instructions to remand to the District Court for further proceedings consistent with this opinion.
It is so ordered.
Justice Brennan and Justice Marshall took no part in the decision of these cases.
