The National Labor Relations Board applied to the district court for orders *428to enforce certain subpoenas duces tecum and ad testificandum which the Board claimed to have issued pursuant to Section 11(1) of the National Labor Relations Act.1 The jurisdiction of the district court was based on Section 11(2) of the Act.2 The district court “quashed” the subpoenas upon the grounds, (1) that they were unreasonable, burdensome and oppressive and (2) that they were not issued upon application of a “party” to the proceedings before the Board. It failed to pass upon a third ground to the effect that the applications for enforcement were premature because the Board had not itself, under Section 11(1) [footnote (1), supra], considered and ruled on petitions to revoke each of said subpoenas. If the third ground is good, then there has been no such final administrative action as is prerequisite to judicial review or enforcement,3 and, as a matter of law, there has been no “contumacy or refusal to obey a subpoena.” Section 11 (2) [Footnote (2), supra]. At the threshold, therefore, we give consideration to the third ground.
Each and all of the respondents, ap-pellees, had filed with the National Labor Relations Board petitions to revoke the subpoenas together with requests for permission to file briefs and present oral arguments in support of their petitions. • The Board, calling attention to Section 102.58(c) of its Rules, 29 C.F.R., § 102.58(c),4 refused to entertain the pe*429titions. The hearing officer undertook to deny the petitions to revoke. The respondents did not request “special permission of the Board” to appeal.5
One of the subpoenas directed to ap-pellee Oliver Jenkins was a subpoena ad testificandum, as to which there appears no provision in the Act for a petition to revoke [see Section 11(1), Footnote (1), supra], and hence the application for its enforcement was not premature on that ground.
All of the other subpoenas were subpoenas duces tecum and the petitions to revoke, while not couched in the language of the statute, sufficiently raised the point of relevancy, that is, that “the evidence whose production is required does not relate to any matter under investigation or any matter in question in such proceedings.” Section 11(1), Footnote (1), supra. As to the subpoenas duces tecum, then, the primary question is whether the Act empowers the Board to delegate to hearing officers the power to pass upon such petitions to revoke.
We think that that question is answered in the negative by the carefully worded provisions of Section 11(1) of the Act, Footnote (1), supra. There the gradations in authority are explicitly delimited. “The Board, or its duly authorized agents or agencies” are given access to and the right to copy evidence. Upon the application of any party, “the Board, or any member thereof” is required “forthwith” to issue subpoenas. At that stage there is no discretion. However, any person served with a subpoena duces tecum “may petition the Board to revoke, and the Board shall revoke, such subpena if in its opinion” etc. (Emphasis supplied.)
It may be, as stated in N. L. R. B. v. Pesante, D.C.S.D.Cal., 119 F.Supp. 444, 450, 451, 452, that the legislative history of the Act further supports such construction. We think, however, that the language itself of Section 11(1) of the Act is plain, and that a different construction is not authorized by any other part of the Act nor by the Act as a whole.
The Seventh Circuit’s remarks about petitions to revoke in N. L. R. B. v. John S. Barnes Corp., 7 Cir., 178 F.2d 156, 160, were necessarily dicta as it does not appear that any such petition was filed in that case.
An administrative remedy under which any person served with a subpoena duces tecum may seek protection from the *430Board itself to make certain that the evidence is described with sufficient particularity and is relevant to the inquiry should not, we believe, prove unduly burdensome to the Board. If it does the remedy lies with Congress, not with the courts. In most cases, methods less burdensome to the respondents than subpoenas duces tecum are available to the Board, such as the right of “the Board, or its duly authorized agents or agencies” to have access to and to copy any evidence, supplemented if need be by the use of subpoenas ad testificandum, required to be issued upon the application of any party.
The reasoning of the Supreme Court in Cudahy Packing Co. v. Holland, 315 U.S. 357, 363, 62 S.Ct. 651, 86 L.Ed. 895, is highly persuasive that the Board has no authority to delegate its power to revoke a subpoena:
“Unlimited authority of an administrative officer to delegate the exercise of the subpoena power is not lightly to be inferred. It is a power capable of oppressive use, especially when it may be indiscriminately delegated and the subpoena is not returnable before a judicial officer. Under the present Act, the subpoena may, as in this case, be used to compel production at a distant place of practically all of the books and records of a manufacturing business, covering considerable periods of time. True, there can be no penalty incurred for contempt before there is a judicial order of enforcement. But the subpoena is in form an official command, and even though improvidently issued it has some coercive tendency, either because of ignorance of their rights on the part of those whom it purports to command or their natural respect for what appears to be an official command, or because of their reluctance to test the subpoena’s validity by litigation. All these are cogent reasons for inferring an intention of Congress not to give unrestricted authority to delegate the subpoena power which it has in terms granted only to the responsible head of the agency.” 315 U.S. at pages 363-364, 62 S.Ct. at page 655.
Nothing in the later case of Fleming v. Mohawk Co., 331 U.S. 111, 67 S.Ct. 1129, 91 L.Ed. 1375, seems to us to lead toward a different construction of the Act now under consideration.6
Under the Act, we think that the Board’s jurisdiction to pass on petitions to revoke subpoenas duces tecum is original, not appellate, that the denial of the petitions by the hearing officer was a mere nullity, and that the respondents were not required to request “special permission of the Board” to appeal. The petitions to revoke were addressed to and filed with the Board itself, and until the Board has passed upon the petitions one way or the other, there is no “contumacy or refusal to obey a subpena” [see 11(2) of the Act, Footnote (2), supra], and the matter of the enforcement of the subpoenas is not ripe for consideration of the court. We hold, therefore, that the district court should have declined to rule upon the enforcement of the subpoenas duces tecum.7
The subpoena ad testificandum directed to appellee Oliver Jenkins is not claimed to be oppressive or burdens*431ome.8 Was it properly quashed because not issued upon the application of a “party” to the proceedings before the Board? The subpoena was sought in a representation proceeding brought under Section 9(c) of the Act, 29 U.S.C.A. 159(c) (l).9 The labor organization and the employer are usually adversely interested in such a proceeding. The proceeding is, however, an “investigation.” 10 “The employer is, in theory at least, not much concerned, since the employees are to choose their representative unhindered.” N. L. R. B. v. Whittier Mills Co., 5 Cir., 111 F.2d 474, 478. The Board is charged with the responsibility of conducting the representation investigation, and the express terms of the statute authorize the Board to use subpoenas in aid of its investigations.11 Section 102.8 of the Board's Rules and Regulations, 29 C.F.R., Sec. 102.8, 1956 Supp., defines “party” as including “the regional director in whose region the proceeding is pending,”12 though we do not consider that important to a decision of the present question. The language of the statute authorizing the use of subpoenas in investigations, while requiring their issuance upon the application of any “party,” may appear to be conflicting but the purpose is clear.
Contrary to the district court in N. L. R. B. v. Pesante, supra, 119 F.Supp. at page 457, we can see no objection to the Board member-furnishing the subpoenas under his signature to the Regional Director to be used by the Director in such investigations as required. We think that the district court erred in declining to enforce the subpoena ad testificandum directed to Oliver Jenkins, and in not declining to rule upon the enforcement *432of the subpoenas duces tecum. One-sixth of the cost of appeal is taxed against the appellees, and the other five-sixths against the appellant. The judgment is reversed and the cause remanded for further proceedings not inconsistent with this opinion.
Reversed and remanded.
