Majority — Frankfurter J.
delivered the opinion of the' Court.
We brought these two cases here, 310 U. S. 617 , because they raise questions of importance touching the distribution of judicial authority under the Communications Act of 1934. (Act of June 19, 1934, 48 Stat. 1064 , as amended by the Act of June 5, 1936, 49 Stat. 1475 , and by the Act of May 20, 1937, 50 Stat. 189 ; 47 U. S. C. § 151 et seq.)
Insofar as action of the Federal Communications Commission is subject to judicial review, the Act bifurcates access to the lower federal courts according to the nature of the subject matter before the Commission. Barring the exceptions immediatelv to be noted. § 402 (a) assimi
■ Our problem, then, is to apply this scheme of jurisdiction to the situation before us. Acting under § 310 (b). of the Communications Act, the Commission refused consent to an assignment to the Columbia Broadcasting ' System of California of a radio station license held by the ^Associated Broadcasters. Columbia arid Associated ' thereupon sought in the Court of AppealsTor the District review of the Commission’s denial of consent. The Commission moved to dismiss the appeals for want of jurisdiction. The court below,, with one justice dissenting, ■deniéd the motions, arid entertained jurisdiction. 71 App. D. C. 206 ; 108 F. 2d 737 .
The crux of the controversy is whether an order of the Commission, in the .'exercise of its authority under § 310 •(b), denying consent to an assignment of a radio station ' license is an order “refusing an application ... for.
Primarily, our task is to read what Congress has written. As a matter of common speech, the excepted types of orders which alone can come before the Court of Ap peals for -the District of Columbia do not include an order refusing the consent required by § 310 (b). Refusing “an application .-. . for a radio station license” is-hardly an apt way to characterize refusal to assent to the transfer of such a license from an existing holder. - Nor is there, anything to indicate that the peculiar idiom of the industry or of administrative practice has modified
1 Sec. 402:'“(a) The provisions of the Act of October 22, 1913 ( 38 Stat. 219 ), relating to the enforcing or setting .aside of the'orders of' the Interstate Commerce Commission, are hereby made applicable-to suits to enforce, enjoin, sét aside, annul, or suspend any order of the Commission under this Act (except any order of the Commission granting or refusing an application for a construction permit for a radio station,- or for a radio station license, or for renewal of an existing radio station license, or for modification of an existing radio station license, or suspending a radio operator’s license) and such ’.suits are hereby authorized to be brought as provided in that Act. - . - “(b) An appeal may be taken, in' the maimer hereinafter provided, from decisions of the Commission to the Court Of Appeals of the Dis-tricf of Columbia in any of the following cases: “(1) By any applicant for a construction permit for a- radio station, or for a radio station license, or for renewal of an existing radio station license, or for modification of an existing radio station license, whose application is refused by the Commission. “(2)’ By any other person aggrieved or whose interests are adversely affected by any decision of the Commission granting or refusing any such application. v(3) By any radio operator whose license has been suspended by the Commission.” If the assignee is covered § 402 (b) (1) the assignor' would be within § 402 (b) (2).
• A sensible reading of the jurisdictional provisions in the context of the. substantive provisions to which they relate gives no warrant for denying significance to the classification made by Congress between those orders for which review can only come before the local district courts, and" those five types of orders, explicitly characterized, which alone can come before the Court of. Appeals for the District. And an order denying consent to an application for a transfer is not one of those five, for it is not an application for “a radio station license” in any fair intendment of that category.
Whát thus appears clear from a reading of the Communications Act itself is not modified by the collateral materials which have been pressed upon us. That both, sides invoke the same extrinsic aids, one to fortify and the other to nullify the conclusion we have reached, in itself proves what dubious light- they shed. What was said in Committee Reports, and some remarks by the proponent of the measure in the Senate, are sufficiently ambiguous insofar as this narrow-issue is concerned, to invite mutually destructive dialectic, but not strong enough either to strengthen or weaken the force of what
