Majority — Hughes C.J.
delivered the opinion of the Court.
This case presents the questions of the effect of a determination by the Interstate Commerce Commission, for the purposes of the Railway Labor Act, that the respondent is not an interurban electric railway, and of the scope of judicial review of that determination.
The Railway Labor Act, which applies to railroads engaged in interstate commerce, excepts any “interurban” electric railway unless it is operating as a part of a general steam-railroad system of transportation.[1] The Interstate Commerce Commission is “authorized and directed upon request of the Mediation Board or upon complaint of any party interested to determine after hearing whether any line operated by electric power” falls within the exception. At the request of the Mediation Board, the Interstate Commerce Commission after hearing determined that the lines of respondent, the Utah Idaho Central Railroad Company, do not constitute an interurban electric railway. 214 I. C. C. 707 . The Mediation Board ordered respondent to post the formal notice prescribed by § 2, Eighth, of the Railway Labor Act.[2] Respondent did not comply. Failure to publish the notice subjects “the carrier, officer or agent offending” to criminal penalties.[3] Respondent, insisting that its line is an interurban electric railway and thus excepted from the Railway Labor Act, and alleging the invalidity of the Act, brought this suit against the United States Attorney for the District of
The District Court took jurisdiction, permitted respondent to try the question de novo, decided that respondent was an interurban electric railway, and granted a permanent injunction. The Circuit Court of Appeals affirmed. 95 F. 2d 911 . We granted certiorari.
As respondent, however characterized, is engaged in interstate transportation, the question whether it should be subjected to the requirements of the Railway Labor Act relating to the adjustment of labor disputes, was one for the decision of Congress. These requirements were prescribed in the exercise by Congress of its constitutional control over interstate commerce. Texas & New Orleans R. Co. v. Railway Clerks, 281 U. S. 548 ; Virginian Railway Co. v. System Federation No. 40, 300 U. S. 515 . As Congress was free to establish the categories which should be excepted, Congress could bring to its aid an administrative agency to determine the question of fact whether a particular railroad fell within the exception, and Congress could make that factual determination, after hearing and upon evidence, conclusive. St. Joseph Stock Yards Co. v. United States, 298 U. S. 38 , 51. For that purpose Congress could create a new administrative agency or use one already existing. And as the questions of fact involved would relate to methods of railroad transportation, and thus to a field in which the Interstate Commerce Commission had peculiar expertness, Congress could fittingly commit the determination to that body.
Congress did not define the term “interurban.” Despite the desirability of such a definition[4] and the diffi

In the instant case, the Interstate Commerce Commission has made the determination contemplated by the statute and we are not concerned with the questions which might arise in its absence. The Commission’s determination was one of fact. Shannahan v. United States, 303 U. S. 596 , 599. What effect shall be ascribed to it? The argument is pressed that the determination is at best persuasive and not in any wise binding upon the courts. It is urged that the Commission was restricted to determining whether respondent was operated as a part of a general steam-railroad system of transportation, which concededly it was not; that the determination of the Commission was not an “order”; that Congress has not manifested an intention that the determination should be binding in judicial proceedings and that in the nature of things it could not be made binding in criminal prosecutions.
We are unable to agree with the view expressed in the court below that the Commission was confined to determining whether respondent was operated as a part of a
In considering the effect of the Commission’s determination, the fundamental question is the intent of Congress. The language of the provision points to definitive action. The Commission is to “determine.” The Commission must determine “after hearing.” The requirement of a “hearing” has obvious reference “to the tradi-. tion of judicial proceedings in which evidence is received and weighed by the trier of the facts.” The “hearing” is “the hearing of evidence and argument.” Morgan v. United States, 298 U. S. 468 , 480. And the manifest purpose in requiring a hearing is to comply with the requirements of due process upon which the parties affected by the determination of an administrative body are entitled to insist. Interstate Commerce Comm’n v. Louisville & Nashville R. Co., 227 U. S. 88 , 91. The Commission is not only authorized but “directed” to give the hearing and make the determination when requested. We cannot think that a determination so prescribed and safeguarded was intended to have no legal effect. On the contrary, in view of the nature and purpose of the proceeding, we must regard the determination as binding , on both the carrier and the Mediation Board. The latter having obtained the determination could not ignore it; neither could the carrier.
We have held that the determination of the Commission is not an “order” reviewable under the Urgent De

What is the scope of the judicial review to which respondent is entitled? As Congress had constitutional authority to enact the requirements of the Railway Labor Act looking to the settlement of industrial disputes between carriers engaged in interstate commerce and their employees,[12] and could include or except interurban carriers as it saw fit, no constitutional question is presented calling for the application of our decisions[13] with respect

S. 679 , 689; Tagg Bros. & Moorhead v. United States, 280 U. S. 420 , 443, 444; Phillips *185 v. Commissioner, 283 U. S. 589 , 600; Crowell v. Benson, 285 U. S. 22 , 60; State Corporation Comm’n v. Wichita Gas Co., 290 U. S. 561 , 569.
The condition which Congress imposed was that the Commission should make its determination after hearing. There is no question that the Commission did give a hearing. Respondent appeared and the evidence which it offered was received and considered. The sole remaining question would be whether the Commission in arriving at its determination departed from the applicable rules of law and whether its finding had a basis in substantial evidence or was arbitrary and capricious. Id. That question must be determined upon the evidence produced before the Commission'.
Taking that position, petitioners unsuccessfully objected in the District Court to the admission of new evidence. But that evidence was substantially the same
14 See United States v. Chicago North Shore & M. R. Co., 288 U. S. 1 , 13, 14.
It cannot be said upon this evidence, and the related facts summarized in the Commission's report, that the Commission’s determination lacked support or was arbitrary or capricious. Nor is there ground for holding that the Commission in reaching its determination departed from applicable principles of law. There is no principle of law which required such a carrier to be classified as an interurban railway. Failing in its effort to obtain a clarifying definition from Congress, the Commission performed its duty in weighing the evidence and reaching its conclusion in the light of the dominant characteristics of respondent’s operations which were fairly comparable to those of standard steam railroads. Compare Piedmont & Northern Ry. Co. v. Interstate Commerce Comm’n, supra, pp. 308-310; United States v. Chicago North Shore & M. R. Co., supra, p. 10.
We conclude that the District Court erred in permitting a trial de novo of that issue and that the determination of the Commission was within its authority validly exercised. The decree of the Circuit Court of Appeals is reversed and the cause is remanded to the District Court with direction to dismiss the bill of complaint.
Reversed.
Mr. Justice Black concurs in the result.
