GUSS, Doing Business as Photo Sound Products Manaufacturing Company, Appellant,v.UTAH LABOR RELATIONS BOARD. No. ___. March 25, 1957. [Syllabus intentionally omitted] Mr. Peter W. Billings, Salt Lake City, Utah, for appellant. Mr. E. R. Callister, Atty. Gen., of Utah, Salt Lake City, Utah, for appellee. Mr. Chief Justice WARREN delivered the opinion of the Court. 1 The question presented by this appeal and by Amalgamated Meat Cutters, etc. v. Fairlawn Meats, Inc., 353 U.S. 20, 77 S.Ct. 604, and San Diego Building Trades Council v. Garmon, 353 U.S. 26, 77 S.Ct. 607, is whether Congress, by vesting in the National Labor Relations Board jurisdiction over labor relations matters affecting interstate commerce, has completely displaced state power to deal with such matters where the Board has declined or obviously would decline to exercise its jurisdiction but has not ceded jurisdiction pursuant to the proviso to § 10(a) of the National Labor Relations Act.1 It is a question we left open in Building Trades Council v. Kinard Construction Co., 346 U.S. 933, 74 S.Ct. 373, 98 L.Ed. 423. 2 Some background is necessary for an understanding of this problem in federal-state relations and how it assumed its present importance. Since it was first enacted in 1935, the National Labor Relations Act2 has empowered the National Labor Relations Board 'to prevent any person from engaging in any unfair labor practice * * * (defined by the Act) affecting commerce.'3 By this language and by the definition of 'affecting commerce' elsewhere in the Act,4 Congress meant to reach to the full extent of its power under the Commerce Clause. National Labor Relations Board v. Fainblatt, 306 U.S. 601, 606—607, 59 S.Ct. 668, 672, 83 L.Ed. 1014. The Board, however, has never exercised the full measure of its jurisdiction. For a number of years, the Board decided case-by-case whether to take jurisdiction. In 1950, concluding that 'experience warrants the establishment and announcement of certain standards' to govern the exercise of its jurisdiction, Hollow Tree Lumber Co., 91 N.L.R.B. 635, 636, the Board published standards, largely in terms of yearly dollar amounts of interstate inflow and outflow.5 In 1954, a sharply divided Board, see Breeding Transfer Co., 110 N.L.R.B. 493, revised the jurisdictional standards upward.6 This Court has never passed and we do not pass today upon the validity of any particular declination of jurisdiction by the Board or any set of jurisdictional standards.7 3 How many labor disputes the Board's 1954 standards leave in the 'twilight zone' between exercised federal jurisdiction and unquestioned state jurisdiction is not known.8 In any case, there has been recently a substantial volume of litigation raising the question stated at the beginning of this opinion, of which this case is an example.9 4 Appellant, doing business in Salt Lake City, Utah, manufactures specialized photographic equipment for the Air Force on a contract basis. To fulfill his government contracts he purchased materials from outside Utah in an amount 'a little less than $50,000.' Finished products were shipped to Air Force bases, one within Utah and the others outside. In 1953 the United Steelworkers of America filed with the National Labor Relations Board a petition for certification of that union as the bargaining representative of appellant's employees. A consent election was agreed to, the agreement reciting that appellant was 'engaged in commerce within the meaning of Section 2(6), (7) of the National Labor Relations Act.' The union won the election and was certified by the National Board as bargaining representative. Shortly thereafter the union filed with the National Board charges that appellant had engaged in unfair labor practices proscribed by § 8(a)(1), (3) and (5) of the Act.10 Meanwhile, on July 15, 1954, the Board promulgated its revised jurisdictional standards. The Board's Acting Regional Director declined to issue a complaint. He wrote on July 21: 5 'Further proceedings are not warranted, inasmuch as the operations of the Company involved are predominantly local in character, and it does not appear that it would effectuate the policies of the Act to exercise jurisdiction.' 6 The union thereupon filed substantially the same charges with the Utah Labor Relations Board, pursuant to the Utah Labor Relations Act.11 Appellant urged that the State Board was without jurisdiction of a matter within the jurisdiction of the National Board. The State Board, however, found it had jurisdiction and concluded on the merits that appellant had engaged in unfair labor practices as defined by the Utah Act. It granted relief through a remedial order. On a Writ of Review, the Utah Supreme Court affirmed the decision and order of the state administrative agency.12 We noted probable jurisdiction. 352 U.S. 817, 77 S.Ct. 65. 7 On these facts we start from the following uncontroverted premises: 8 (1) Appellant's business affects commerce within the meaning of the National Labor Relations Act and the National Labor Relations Board had jurisdiction. National Labor Relations Board v. Fainblatt, supra. 9 (2) The National Act expressly deals with the conduct charged to appellant which was the basis of the state tribunals' actions. Therefore, if the National Board had not declined jurisdiction, state action would have been precluded by our decision in Garner v. Teamsters Union, 346 U.S. 485, 74 S.Ct. 161, 98 L.Ed. 228. 10 (3) The National Board has not entered into any cession agreement with the Utah Board pursuant to § 10(a) of the National Act. Section 10(a) provides: 11 'The Board is empowered, as hereinafter provided, to prevent any person from engaging in any unfair labor practice (listed in Section 8) affecting commerce. This power shall not be affected by any other means of adjustment or prevention that has been or may be established by agreement, law, or otherwise: Provided, That the Board is empowered by agreement with any agency of any State or Territory to cede to such agency jurisdiction over any cases in any industry (other than mining, manufacturing, communications, and transportation except where predominantly local in character) even though such cases may involve labor disputes affecting commerce, unless the provision of the State or Territorial statute applicable to the determination of such cases by such agency is inconsistent with the corresponding provision of this Act or has received a construction inconsistent therewith.' (Emphasis added.) 12 The proviso to § 10(a), italicized in the quotation above, was one of the Taft-Hartley amendments to the National Labor Relations Act. Timing and a reference in one of the committee reports indicate that it was drafter in response to the decision of this Court in Bethlehem Steel Co. v. New York State Labor Relations Board, 330 U.S. 767, 67 S.Ct. 1026, 91 L.Ed. 1234.13 In Bethlehem foremen in an enterprise affecting commerce petitioned the New York State Labor Relations Board for certification as a bargaining unit. At that time the National Board was declining, as a matter of policy, to certify bargaining units composed of foremen. The Court held that the federal policy against certifying foremen's units must prevail. However, it took occasion to discuss the efforts of the two boards to avoid conflicts of jurisdiction. 13 'The National and State Boards have made a commendable effort to avoid conflict in this overlapping state of the statutes. We find nothing in their negotiations, however, which affects either the construction of the federal statute or the question of constitutional power insofar as they are involved in this case, since the National Board made no concession or delegation of power to deal with this subject. The election of the National Board to decline jurisdiction in certain types of cases, for budgetary or other reasons presents a different problem which we do not now decide.' Id., 330 U.S. at page 776, 67 S.Ct. at page 1031. 14 Three Justices were led to concur specially, because, as it was stated for the three: 15 'I read * * * (the Court's opinion) to mean that it is beyond the power of the National Board to agree with State agencies enforcing laws like the Wagner Act to divide, with due regard to local interests, the domain over which Congress had given the National Board abstract discretion but which, practically, cannot be covered by it alone. If such cooperative agreements between State and National Boards are barred because the power which Congress has granted to the National Board ousted or superseded State authority, I am unable to see how State authority can revive because Congress has seen fit to put the Board on short rations.' Id., 330 U.S. at page 779, 67 S.Ct. at page 1032. 16 Thus, if the opinion of the Court did not make manifest, the concurring opinion did, that after Bethlehem there was doubt whether a state board could act either after a formal cession by the National Board or upon a declination of jurisdiction 'for budgetary or other reasons.' When we read § 10(a) against this background we find unconvincing the argument that Congress meant by the proviso only to meet the first problem, i.e., cession of jurisdiction over cases the National Board would otherwise handle. 17 The proviso is directed at least equally to the type of cases which the Board might decline 'for budgetary or other reasons' to hear as to the type of cases it might wish to cede to the States for policy reasons—if, indeed, there is any difference between the two classes. Cases in mining, manufacturing, communications and transportation can be ceded only where the 'industry' is 'predominantly local in character.' In other industries, which Congress might have considered to be more or less typically local, it put no such limitation on the Board's power. The Senate Committee spelled the matter out: 18 'The proviso which has been added to this subsection (§ 10(a)) permits the National Board to allow State labor-relations boards to take final jurisdiction of cases in borderline industries (i.e., border line insofar as interstate commerce is concerned), provided the State statute conforms to national policy.'14 19 The Committee minority agreed as to the purpose of the proviso and agreed 'with the majority that it is desirable thus to clarify the relations between the National Labor Relations Board and the various agencies which States have set up to handle similar problems.'15 20 We hold that the proviso to § 10(a) is the exclusive means whereby States may be enabled to act concerning the matters which Congress has entrusted to the National Labor Relations Board. We find support for our holding in prior cases in this Court. In Amalgamated Ass'n of St. Elec. Ry. & Motor Coach Employees v. Wisconsin Board, 340 U.S. 383, 397—398, 71 S.Ct. 359, 367, 95 L.Ed. 364, the Court said: 21 'The legislative history of the 1947 Act refers to the decision of this Court in Bethlehem Steel Co. v. New York State Labor Relations Board, 1947, 330 U.S. 767, 67 S.Ct. 1026, 91 L.Ed. 1234, and, in its handling of the problems presented by that case, Congress demonstrated that it knew how to cede jurisdiction to the states. Congress knew full well that its labor legislation 'preempts the field that the act covers insofar as commerce within the meaning of the act is concerned' and demonstrated its ability to spell out with particularity those areas in which it desired state regulation to be operative.' (Footnotes omitted.) 22 In a footnote to the first sentence quoted above the Court cited § 10(a) and described its authorization to cede jurisdiction only where the state law is consistent with the national legislation as insuring 'that the national labor policy will not be thwarted even in the predominantly local enterprises to which the proviso applies.' Id., 71 S.Ct. 367, note 23. See also Algoma Plywood & Veneer Co. v. Wisconsin Board, 336 U.S. 301, 313, 69 S.Ct. 584, 590, 93 L.Ed. 691; People of State of California v. Zook, 336 U.S. 725, 732, 69 S.Ct. 841, 844, 93 L.Ed. 1005. 23 Our reading of § 10(a) forecloses the argument based upon such cases as H. P. Welch Co. v. New Hampshire, 306 U.S. 79, 59 S.Ct. 438, 83 L.Ed. 500, and Missouri Pacific R. Co. v. Larabee Flour Mills Co., 211 U.S. 612, 29 S.Ct. 214, 53 L.Ed. 352, that 'where federal power has been delegated but lies dormant and unexercised,' Bethlehem Steel Co. v. New York State Labor Relations Board, supra, 330 U.S. at page 775, 67 S.Ct. at page 1031, the States' power to act with respect to matters of local concern is not necessarily superseded. But in each case the question is one of congressional intent. Compare H. P. Welch Co. v. New Hampshire, supra, with Napier v. Atlantic Coast Line R. Co., 272 U.S. 605, 47 S.Ct. 207, 71 L.Ed. 432. And here we find not only a general intent to pre-empt the field but also the proviso to § 10(a), with its inescapable implication of exclusiveness. 24 We are told by appellee that to deny the State jurisdiction here will create a vast no-man's-land, subject to regulation by no agency or court. We are told by appellant that to grant jurisdiction would produce confusion and conflicts with federal policy. Unfortunately, both may be right. We believe, however, that Congress has expressed its judgment in favor of uniformity. Since Congress' power in the area of commerce among the States is plenary, its judgment must be respected whatever policy objections there may be to creation of a no-man's-land. 25 Congress is free to change the situation at will. In 1954 the Senate Committee on Labor and Public Welfare recognized the existence of a no-man's-land and proposed an amendment which would have empowered state courts and agencies to act upon the National Board's declination of jurisdiction.16 The National Labor Relations Board can greatly reduce the area of the no-man's-land by reasserting its jurisdiction and, where States have brought their labor laws into confromity with federal policy, by ceding jurisdiction under § 10(a).17 The testimony given by the Chairman of the Board before the Appropriations Committees shortly before the 1954 revisions of the jurisdictional standards indicates that its reasons for making that change were not basically budgetary. They had more to do with the Board's concept of the class of cases to which it should devote its attention.18 26 The judgment of the Supreme Court of Utah is 27 Reversed. 28 Mr. Justice WHITTAKER took no part in the consideration or decision of this case. 29 Mr. Justice BURTON, whom Mr. Justice CLARK joins, dissenting. 30 I believe the Court is mistaken in its interpretation of the proviso which Congress added to § 10(a) of the National Labor Relations Act in 1947.1 It is my view that the proviso was added merely to make it clear that the National Labor Relations Board had the power, by making specific agreements, to cede jurisdiction to state or territorial agencies over certain labor disputes. Congress sought thereby to facilitate state cooperation in the supervision of labor practices affecting interstate commerce. The Court is not justified in interpreting this action as evidencing an unexpressed and sweeping termination of the States' pre-existing power to deal with labor matters over which the Board, for budgetary or other administrative reasons, has declined, or obviously would decline, to exercise its full jurisdiction. 31 The Labor Acts of 1935 and 1947 granted to the Board extensive jurisdiction over labor controversies affecting interstate commerce but neither Act required the Board to assert at all times the full measure of its jurisdiction. In each Act the first sentence of § 10(a) 'empowered,' but did not direct, the Board to prevent unfair labor practices. Likewise, the first sentence of § 10(b) granted the 'power,' instead of imposing the duty, to issue complaints upon receipt of appropriate charges.2 The Board is not a court whose jurisdiction over violations of private rights must be exercised. It is an administrative agency whose function is to adjudicate public rights in a manner that will effectuate the policies of the Act. See Amalgamated Utility Workers v. Consolidated Edison Co., 309 U.S. 261, 60 S.Ct. 561, 84 L.Ed. 738. 32 From the beginning, budgetary limitations and other administrative considerations have prevented the Board from exercising jurisdiction over all cases in which interstate commerce was affected. Congress knew this when, in 1947, it left unchanged the discretionary language of § 10 and added the proviso to § 10(a). Congress has consistently refrained from appropriating funds sufficient to permit the Board to entertain all complaints within its jurisidction. In recent years Congress has repeatedly recognized the Board's jurisdictional practice.3 In National Labor Relations Board v. Denver Bldg. & Trades Council, 341 U.S. 675, 684, 71 S.Ct. 943, 949, 95 L.Ed. 1284, this Court said that 'Even when the effect of activities on interstate commerce is sufficient to enable the Board to take jurisdiction of a complaint, the Board sometimes properly declines to do so, stating that the policies of the Act would not be effectuated by its assertion of jurisdiction in that case.' Courts of Appeals have approved the Board's practice4 and none of the parties to the instant cases question it. 33 Unless restricted by the proviso added to § 10(a), there is title doubt that the States have the necessary power to act in labor controversies within their borders, even when interstate commerce is affected, provided the Federal Government has not occupied the field and the National Board has not taken jurisdiction. Where the Board has declined, or obviously would decline, to take jurisdiction, then federal power lies 'dormant and unexercised.' Bethlehem Steel Co. v. New York State Labor Relations Board, 330 U.S. 767, 775, 67 S.Ct. 1026, 1031, 91 L.Ed. 1234. Unless the proviso stands in their way, the States may then exercise jurisdiction since their action will not conflict with the Board's administration of the Act.5 Substantive provisions of the Act may limit the action of the States. See United Mine Workers v. Arkansas Oak Flooring Co., 351 U.S. 62, 75, 76 S.Ct. 559, 566, 100 L.Ed. 941. But the States are not deprived of all power to act.6 34 By this decision the Court restricts the power of the State to those labor disputes over which the National Board expressly cedes its jurisdiction to the appropriate state agencies. However, the proviso's requirements are so highly restrictive that not a single cession has been made under it.7 The result of this decision is the creation of an extensive no man's land within which no federal or state agency or court is empowered to deal with labor controversies. It is difficult to believe that Congress, sub silentio, intended to take such a step backward in the field of labor relations. 35 The immediate occasion that led to the enactment of the proviso throws light on its proper interpretation. That occasion was this Court's decision in the Bethlehem case, supra, where it was held that a State Board did not have jurisdiction to certify a union of foremen as a collective-bargaining agency because the National Board, by asserting general jurisdiction over foremen's unions, had occupied the field.8 Although an agreement had been negotiated between the National Board and the State Board ceding jurisdiction over certain labor matters, this Court concluded that the agreement did not cede jurisdiction over foremen's unions. Three Justices decried certain overtones they found in the opinion of the Court to the effect that the National Board lacked authority to cede jurisdiction over predominantly local labor matters by agreement with state agencies. It was to clarify the power of the National Board to make such a cession that the proviso was added to § 10(a). 36 While the proviso thus evidenced a congressional purpose to encourage state action, there is no indication that it was intended to wipe out, by implication, the States' recognized power to act when the National Board declined to take jurisdiction. Neither the language of the proviso nor its legislative history discloses a conscious congressional intent to eliminate state authority when the National Board has declined to act. Unequivocal legislative history would be necessary to sustain a conclusion that Congress intended such a drastic result. In the Bethlehem case, supra, the Court did not question the authority of the States to act when the Board, for budgetary or other administrative reasons, declined to exercise its full jurisdiction. The Court expressly refrained from passing on that question9 but three Justices said that they found in the opinion of the Court a 'suggestion that the National Board's declination of jurisdiction 'in certain types of cases, for budgetary or other reasons' might leave room for the State in those situations * * *.' 330 U.S., at page 778, 67 S.Ct. at page 1032. 37 As a matter of fact, in 1947, nearly 40 States lacked labor agencies and comprehensive labor legislation.10 Obviously, those States were ineligible to take advantage of the proviso. It is hard to imagine that Congress meant to make the proviso the exclusive channel for state jurisdiction when so many States would be automatically excluded from using it. The full mission of the proviso was to supply the National Board with express authority to cede jurisdiction over labor disputes by agreement where, as a matter of deliberate judgment, it concluded that due regard for local interests made that course desirable. The Board's jurisdictional yardsticks always have reflected its need to distribute its limited resources so as best to effectuate the policies of the Act. The Board does not 'cede' jurisdiction when it declines to exercise its full jurisdiction; it merely allows the States to exercise their pre-existing authority.11 38 The Court's interpretation of the proviso is contrary to the established practice of the States and of the National Board, as well as to the considered position taken by the Board as amicus curiae. Congress has demonstrated a continuing and deep interest in providing governmental machinery for handling labor controversies. The creation by it of a large, unsupervised no man's land flies in the face of that policy. Due regard for our federal system suggests that all doubts on this score should be resolved in favor of a conclusion that would not leave the States powerless when the federal agency declines to exercise its jurisdiction. As three Justices said in the Bethlehem case, supra: 39 'Since Congress can, if it chooses, entirely displace the States to the full extent of the far-reaching Commerce Clause, Congress needs no help from generous judicial implications to achieve the supersession of State authority. To construe federal legislation so as not needlessly to forbid preexisting State authority is to respect our federal system. Any indulgence in construction should be in favor of the States, because Congress can speak with drastic clarity whenever it chooses to assure full federal authority, completely displacing the States.' 330 U.S., at page 780, 67 S.Ct. at page 1033. 40 I would sustain the jurisdiction of the respective States in these cases. 1 61 Stat. 146, 29 U.S.C. § 160(a), 29 U.S.C.A. § 160(a). 2 49 Stat. 449, as amended, 61 Stat. 136, 29 U.S.C. § 151 et seq., 29 U.S.C.A. § 151 et seq. 3 § 10(a), 49 Stat. 453, left unchanged in this particular by the Taft-Hartley amendments, 61 Stat. 146, 29 U.S.C. § 160(a), 29 U.S.C.A. § 160(a). 4 'The term 'affecting commerce' means in commerce, or burdening or obstructing commerce or the free flow of commerce, or having led or tending to lead to a labor dispute burdening or obstructing commerce or the free flow of commerce.' § 2(7), 49 Stat. 450, left unchanged by the Taft-Hartley amendments, 61 Stat. 138, 29 U.S.C. § 152(7), 29 U.S.C.A. § 152(7). 5 The NLRB's Press Release of October 6, 1950, can be found at 26 LRR Man. 50. 6 The NLRB's Press Release of July 15, 1954, can be found at 34 LRR Man. 75. 7 But see National Labor Relations Board v. Denver Building & Construction Trades Council, 341 U.S. 675, 684, 71 S.Ct. 943, 949, 95 L.Ed. 1284. 8 Members of the Board disagreed as to the impact of the revision. See Breeding Transfer Co., 110 N.L.R.B. 493, 498—500, 506—508. 9 Among the cases in which courts have sustained state jurisdiction where the Board declines or would decline jurisdiction are Garmon v.

The proviso to § 10(a) first appeared when S. 1126, which contained the substance of what was to become the Taft-Hartley Act, was reported out of committee April 17. See S.Rep.

The minority members also said, 'We think the clarification of relations between the Federal and State boards contemplated under section 10(a) a wise solution to a complex problem.' Id., at 41. See also S.Rep. No. 986, 80th Cong., 2d Sess. 30—31. 16 'The effect * * * of the Board's policy of refusing to assert its jurisdiction has been to create a legal vacuum or no-man's land with respect to cases over which the Board, in its discretion, has refused to assert jurisdiction. In these cases the situation seems to be that the Board will not assert jurisdiction, the States are forbidden to do so, and the injured parties are deprived of any forum in which to seek relief.' S.Rep. No. 1211, 83d Cong., 2d Sess. 18. The minority agreed that 'When the Federal Board refuses to take a case within its jurisdiction, the State agencies or courts are nevertheless without power to take jurisdiction, since the dispute is covered by the Federal act, even though the Federal Board declines to apply the act. There is thus a hiatus—a no man's land—in which the Federal Board declines to exercise its jurisdiction and the State agencies and courts have no jurisdiction.' Id., Pt. 2, P. 14. The Committee's bill, S. 2650, was recommitted. 100 Cong.Rec. 6203. 17 The National Labor Relations Board has informed us in its brief amicus curiae in these cases that it has been unable, because of the conditions prescribed by the proviso to § 10(a), to consummate any cession agreements. 18 Hearings before Subcommittee of House Committee on Appropriations, Department of Labor and Related Independent Agencies, 83d Cong., 20 Sess. 309, 315, 323. 1 Section 10(a) of the National Labor Relations Act of 1935, 49 Stat. 453, was amended by the Labor Management Relations Act of 1947 by the addition of the proviso shown below: 'Sec. 10(a) The Board is empowered, as hereinater provided, to prevent any person from engaging in any unfair labor practice (listed in section 8) affecting commerce.

United Construction Workers, etc. v. Laburnum Construction Corp., 347 U.S. 656, 665, 74 S.Ct. 833, 838, 98 L.Ed. 1025. See also, Weber v. Anheuser-Busch, Inc., 348 U.S. 468, 479—480, 75 S.Ct. 480, 487, 99 L.Ed. 546. 6 See Southern Pacific Co. v. Arizona ex rel. Sullivan, 325 U.S. 761, 65 S.Ct. 1515, 89 L.Ed. 1915; Terminal Railroad Ass'n v. Brotherhood of Railroad Trainmen, 318 U.S. 1, 63 S.Ct. 420, 87 L.Ed. 571; H. P. Welch Co. v.

Larable Flour Mills Co., 211 U.S. 612, 29 S.Ct. 214, 53 L.Ed. 352. 7 The National Labor Relations Board in its brief filed in these cases states that— 'It should be noted here that the Board has been unable, because of the prescribed conditions, to consummate any such agreements. Congress has been aware of this situation and considered the feasibility of deleting these conditions in order to reduce the tremendous volume of cases brought before the Board. S.Rep.No. 986, JointCommittee Report, 80th Cong., 2d Sess., 31 (1948). Congress, however, has taken no action in this regard. The advocates of federal preemption argue from this post-legislative history that Congress has thereby manifested its intent to preclude State action in the absence of cession by the Board. Precisely what inference may be drawn from such Congressional inaction is, in our judgment, wholly speculative.' 8 '* * * It (the National Board) made clear that its refusal to designate foremen's bargaining units was a determination and an exercise of its discretion to determine that such units were not appropriate for bargaining purposes. Maryland Drydock Co., 49 N.L.R.B. 733. We cannot, therefore, deal with this as a case where federal power has been delegated but lies dormant and unexercised. '* * * The federal board has jurisdiction of the industry in which these particular employers are engaged and has asserted control of their labor relations in general. It asserts, and rightfully so, under our decision in the Packard case, supra (Packard Motor Car Co. v. N.L.R.B., 330 U.S. 485, 67 S.Ct. 789, 91 L.Ed. 1040), its power to decide whether these foremen may constitute themselves a bargaining unit. We do not believe this leaves room for the operation of the state authority asserted.' 330 U.S., at pages 775, 776, 67 S.Ct. at page 1031. 9 'The National and State Boards have made a commendable effort to avoid conflict in this overlapping state of the statutes. We find nothing in their negotiations, however, which affects either the construction of the federal statute or the question of constitutional power insofar as they are involved in this case, since the National Board made no concession or delegation of power to deal with this subject. The election of the National Board to decline jurisdiction in certain types of cases, for budgetary or other reasons presents a different problem which we do not now decide.' 330 U.S., at page 776, 67 S.Ct. at page 1031. 10 In 1947 only 11 States had comprehensive labor statutes. Of those, eight had established an administrative procedure for the adjudication of unfair labor practices while three had left these matters to conventional law-enforcement agencies—prosecuting attorneys and regular courts. See Killingsworth, State Labor Relations Acts (1948), 1—3, 111—112. Labor legislation in the other 37 States was fragmentary. Killingsworth said of these laws 'that they are aimed exclusively at one or a few union practices, place few or no restrictions on employers, and do not attempt to establish a comprehensive labor relations policy.' Id., at 3. 11 When in 1954 the Board revised upward its jurisdictional yardsticks, it stated that 'a desire to establish broader State jurisdiction is in no wise a factor in our decision.' Breeding Transfer Co., 110 N.L.R.B. 493, 497.
