This is an appeal from a district court order granting a petition for an injunction filed by a Regional Director of the N.L.R.B. pursuant to section 10 (l) of the National Labor Relations Act, as amended.1 The petition alleged, and the lower *239court found, there was reasonable cause to believe appellant Local 459 was engaging in conduct violative of section 8(b) (4) (ii) (B) of the Act.2
The evidence disclosed that certain members of appellant employed by Remington Rand Univac Division, Sperry Rand Corporation (Rand), as tabulating service mechanics have been on strike since September, 1961. In the course of this strike, appellant began distributing handbills at the premises of certain businesses which lease equipment, such as tabulators and computors, from Rand. Some, or perhaps all, of this equipment is serviced by Rand employees who are thus performing the struck work. One firm, Macy’s Department Store, also sells consumer products produced by Rand. There is no evidence in the record to indicate whether the other businesses sell Rand products or whether their relations are limited solely to the leasing and servicing of equipment. The handbills appealed to the public not to patronize these firms.
The district judge found there was “reasonable cause,” within the meaning of section 10 (i), to believe the hand-billing violated section 8(b) (4) (ii) (B). Because there is no dispute as to the material facts in evidence and because we are faced solely with questions of law, we need decide only whether the judge below “was wrong, not whether he was ‘clearly’ so.” Empressa Hondurena de Vapores, S. A. v. McLeod, 300 F.2d 222 (2 Cir., Jan. 12, 1962). We believe the injunction should not have been granted because previous Board decisions construing the so-called “publicity proviso” would preclude it from finding an unfair labor practice in this case. Under these circumstances, injunctive relief under section 10 (i) cannot be granted without usurping the function of the Board and violating the congressional intent behind that provision. We must, therefore, reverse.
Prior to the enactment of section 10 (I), federal courts were without jurisdiction to issue injunctions in “labor disputes” under the broad prohibitions of the Norris-LaGuardia Act.3 Passed in 1932, that statute was a manifestation of strong congressional disapproval of the per*240formance of federal courts in labor disputes.4 It was believed the temporary-restraining order and preliminary injunction were inappropriate remedies for such use because they often settled the dispute under the guise of merely preserving the status quo.5 Moreover, Congress believed the federal courts, through the injunctive process, had set themselves up as economic arbiters of labor strife, a function which Congress believed they were institutionally ill-equipped to undertake and which could lead only to the tarnishing of judicial prestige.6 The Legislature believed the formulation of labor policy was essentially a political question and belonged to it.7 The statute, therefore, “was prompted by a desire * * * to withdraw federal courts from a type of controversy for which many believed they were ill-suited and from participation in which, it was feared, judicial prestige might suffer.” 8
When Congress wrote the Taft-Hartley Act in 1947, however, it believed NorrisLaGuardia to be so broad that certain of the new provisions of section 8(b), creating union unfair labor practices, would be rendered nullities without some use of the injunctive process. Section 10 (l), essentially a compromise measure, was enacted to fill this need. Attempts to restore power to the federal courts to issue injunctions in certain labor disputes upon petition by purely private parties were abandoned because “opposition to restoring the injunctive process * * * seemed to be so strong * * * ” that other provisions of the bill were endangered.9 One of the principal arguments employed to defeat these attempts was that the federal courts would once again become too deeply involved in labor disputes without the aid of initial adjudication by an expert agency.10 It is against this background that section 10 (0 must be read.
*241Section 10(£) was designed by Congress to provide a means by which temporary injunctive relief could be obtained “pending the final adjudication of the Board.” Sen.Rep.No. 105 (80th Cong. 1947), p. 27. H.R.Conf.Rep.No.510 (80th Cong.1947), p. 57. It does not provide relief beyond that stage, for Sections 10(e), (f) specify the procedure to be followed after the Board has rendered a decision. These sections allow temporary relief pending appeal or petition for enforcement, but only in aid of the Board order. Those attempting to upset a decision by the Board cannot obtain such relief pending their appeal. It is clear, therefore, that if the Board holds the present case does not involve an unfair labor practice, the injunction affirmed here must be dissolved forthwith, regardless of whether the charging party decides to appeal.
Because section 10 (l) injunctions have only this limited purpose, a finding of “reasonable cause” must be premised on a belief there is a reasonable possibility of the Board sustaining the unfair labor practice charge. But previous Board decisions preclude it from finding an unfair labor practice here without reversing field, and, needless to say, there has been no showing there will be such a reversal. In Lohman Sales Co., 132 N.L.R.B. No. 67, the Board construed the words “product” or “produced,” as used in the so-called “publicity proviso,” to encompass all forms of labor or service and rejected a literal interpretation which would limit them to actual consumer goods. The Board further indicated it would not construe the proviso to “attach special importance to one form of labor over another.” Under this interpretation, the handbilling here would be protected by the “publicity proviso.” Subsequent cases have consistently adhered to this rationale11 and have bolstered the assertion of the dissenter in Lohman that “[t]he net result of this interpretation is to sanction the indiscriminate hand-billing of virtually any business.”
The Regional Director, however, believes the anticipation the Board will abandon this rationale “reasonable,” because, in his view, every factual situation yet ruled upon by the Board involved a “direct connection” between services provided by the primary employer and products distributed by the secondary business.12 He contends there is no such connection here between the tabulators and computors and the products distributed by the handbilled firms.13 We do not believe, however, the Board decisions in question allow for such a distinction. In Golden Dawn Foods, 134 N.L.R.B. No. 73, the Board was faced with two disputes involving two primary employers and one secondary business. The first dispute involved a refrigeration installation and maintenance contractor who employed non-union workers to install and service the refrigeration equipment in the secondary employer’s super market. The Regional Director contends the refrigeration equipment makes eer*242tain products saleable and is thereby “directly connected” with them. Even if we were able to accept this as a viable distinction, it would not dispose of the other dispute which involved an electrical contractor who did all the electrical work in the building. Here indeed was the Board’s golden opportunity to expound upon the “direct connection” test, for the electricity in the building had no such connection with products distributed by the secondary employer. The Board, however, merely said handbilling in both disputes was protected by the publicity proviso “[f]or the reasons stated in the Lohman Sales case * * * ”. Nor has the Regional Director said why Northwestern Construction of Washington, 134 N.L.R.B. No. 46, is distinguishable on the grounds there is a “direct connection” between construction work on a building and products ultimately sold in that building.
In meeting the issues before us, we must be mindful of a key fact relating to the internal structure of the agency itself. Because the prosecutory and judicial functions have been separated within the Board,14 the General Counsel (or his representative, here the Regional Director) acts upon his own authority in issuing unfair labor practice complaints and seeking injunctions. If the General Counsel disagrees with the Board’s interpretation of the statute, there is little to stop him from continuing to issue complaints in the hope of having the Board reverse itself. The decision in Golden Dawn indicates the General Counsel in fact did seek to have Lohman overruled. Whether this is such a case or not is irrelevant, for the danger is there. While we must give great weight to a Regional Director’s finding of reasonable cause, we should not usurp the functions of the Board itself in doing so. The preliminary injunction is of critical importance to participants in labor disputes, for it may have as great an effect upon the dispute as the ultimate outcome of the litigation.15 A careless interpretation of section 10(1), therefore, may make the General Counsel and the federal district courts the actual focal points of unfair labor practice adjudications. But this is precisely the result Norris-LaGuardia and section 10(1) were designed to avoid in their deliberate minimization of the role of the courts in these matters. We must, therefore, defer to the clear purport of Board precedents, whether we believe them right or wrong,16 and dismiss the petition.17
The charging party, Rand, contends the handbills distributed are untruthful and, therefore, not protected by the “publicity proviso.” Because the Regional Director has not relied upon this in his petition or argument, we believe the question governed not by section 10(1), but by the Norris-LaGuardia Act. We lack jurisdiction, therefore, to grant relief. Section 10(1) is operative only upon the filing of a petition by a Regional Director of the Board. This limitation was imposed in order to restrict the potential *243involvement of federal courts in labor disputes. For that reason, we do not read it to allow consideration of issues not raised by the Regional Director. To do otherwise would not only increase the danger of over-involvement on the part of the federal courts but would also ignore the expertise which section 10 (Í) commands us to attribute to the Regional Director. It is his view of the facts and law the district judge is to evaluate in a section 10 (i) proceeding.18 The courts are not free to roam at will over every aspect of a labor dispute upon the request of the charging party. We are mindful of the fact the statute allows the charging party to appear by counsel and present relevant testimony. We believe, however, the principal role in these proceedings is to be played by the Regional Director acting in the public interest, and while the charging party is free to aid him in the course of the litigation, the charging party may not substitute itself as the principal complainant. The reversal here is not a bar to a further petition based upon the alleged untruthful nature of the handbills. The only relief available, of course, would be the enjoining of handbills which are untruthful, not, as the charging party seems to contend, an injunction against all handbilling.

That section provides in part:
“Whenever it is charged that any person has engaged in an unfair labor practice within the meaning of paragraph (4) (A), (B) or (C) of section 158(b) of this title, or section 158(e) of this title or section 158(b) (7) of this title, the preliminary investigation of such charge shall be made forthwith and given priority over all other cases except cases of like character in the office where it is filed or to which it is referred. If, after such investigation, the officer or regional attorney to whom the matter may be referred has reasonable cause to believe such charge is true and that a complaint should issue, he shall on behalf of the Board, petition any United States district court within any district where the unfair labor practice in question has occurred, is alleged to have occurred, or wherein such person resides or transacts business, for appropriate injunctive relief pending the final adjudication of the Board with respect to such matter. Upon the filing of any such petition the district court shall have jurisdiction to grant such injunctive relief or temporary restraining order as it deems just and proper, notwithstanding any other provision of law: Provided further, That no temporary restraining order shall be issued without notice unless a petition alleges that substantial and irreparable injury to the charging party will be unavoidable and such temporary restraining order shall be effective for no longer than five days and will become void at the expiration of such period. * * * Upon filing of any such petition the courts shall cause notice thereof to be served upon any person involved in the charge and such person, including the charging party, shall be given an opportunity to appear by counsel and present any relevant testimony.”

In both Houses of Congress the debate over the passage of Norris-LaGuardia focused on the role of the courts. Senator Norris observed:

“This judge-made law has developed in the past 40 years. The judges have themselves enforced the penalties for the violations of the laws made by them * * * It is because of this development of law made on the bench that our federal courts have lost a great deal of respect.” 75 Cong.Rec. 5463 (1932) (Remarks of Representative O’Connor).

“The public policy laid down in the bill, I think, is essential, because there should be some standard by which the courts may know, at a time when they are in such confusion, what it is proper to do.

. In effect, the Regional Director would have us ignore what was said in Lohman as mere dictum. Even without the subsequent decisions discussed herein, we might well be hard pressed to find it “reasonable” to expect the Board to abandon a rationale recently expressed and clearly designed to govern its consideration of future cases. In any event, we do not believe the lack of a decision precisely on point is by itself sufficient to constitute reasonable cause. Penello v. Local Union No. 59, Sheet Metal Workers, 195 F.Supp. 458, 473 (D.Del.1961).
. The Regional Director’s position in this respect is not abundantly clear. He introduced no evidence to show the relations between Rand and the handbilled firms were limited solely to the leasing and servicing of equipment. Apparently he contends this factor is irrelevant because the handbills made no reference to such products. Because the Board has held in the clearest possible fashion “that the publicity proviso was intended to permit a consumer boycott of a secondary employer’s entire business and not merely a ‘product,’ ” Middle South Broadcasting Co., 133 N.L.R.B. No. 165, we believe such proof was essential to any action premised on the so-called “direct connection” test.
. See generally 2 Davis, Administrative Law §§ 13.01-13.11 (1958).
. The present case is almost a classical example of this. The injunction, coming at the peak of the Christmas season, prevented handbilling at the very time it would have its greatest effect. Our reversal, however, cannot restore the parties to the power relationship existing at that time.
. We express no opinion as to the conflicting interpretations of the statute delineated in Lohman or as to the proper disposition by the Board of the present case. Our decision is limited solely to the role of federal judges issuing injunctions under section 10 (Z). These other issues may be appropriately determined only under section 10(e) and (f).
. We do not hold a district court’s sole inquiry under section 10(Z) is whether anticipation of Board relief is reasonable. We say only that in the absence of such a finding, no relief is obtainable. Having made such finding, however, the court must further find reasonable cause to be-believe that a Board decision finding an unfair labor practice will be enforced by a Court of Appeals. Conversely, the Regional Director must demonstrate some support, both factual and legal, for every element of his case.
. The district judge in this ease was aware of these restrictions and made no findings as to whether the handbills were untruthful.
