Mr. Justice Rehnquist
delivered the opinion of the Court.
Appellees, two railroad companies, brought this action in the District Court for the Middle District of Florida to set aside the incentive per diem rates established by appellant Interstate Commerce Commission in a rule-making proceeding. Incentive Per Diem Charges — 1968, Ex parte No. 252 (Sub-No. 1), 337 I. C. C. 217 (1970). They challenged the order of the Commission on both substantive and procedural grounds. The District Court sustained appellees’ position that the Commission had failed to comply with the applicable provisions of the Administrative Procedure Act, 5 U. S. C. § 551 et seq., and therefore set aside the order without dealing with the railroads’ other contentions. The District Court held that the language of § 1 (14) (a) of the Interstate Commerce Act, 24 Stat. 379, as amended, 49 U. S. C. § 1 (14) (a), required the Commission in a proceeding such as this to act in accordance with the Administrative Procedure Act, 5 U. S. C. § 556 (d), and that the Commission’s determination to receive submissions from the appellees only in written form was a violation of that section because the appellees were “prejudiced” by that determination within the meaning of that section.
Following our decision last Term in United States v. Allegheny-Ludlum Steel Corp., 406 U. S. 742 (1972), we noted probable jurisdiction, 407 U. S. 908 (1972), and requested the parties to brief the question of whether the Commission’s proceeding was governed by 5 U. S. C. § 553, or by §§ 556 and 557, of the Administrative Procedure Act. We here decide that the Commission’s proceeding was governed only by § 553 of that Act, and that appellees received the “hearing” required by § 1 (14) (a) of the Interstate Commerce Act. We, therefore, reverse the judgment of the District Court and remand the case to that court for further consideration of appellees’ other contentions that were raised there, but which we do not decide.
I. Background op Chronic Freight Car Shortages
This case arises from the factual background of a chronic freight-car shortage on the Nation’s railroads, which we described in United States v. Allegheny-Ludlum Steel Corp., supra. Judge Simpson, writing for the District Court in this case, noted that “[f]or a number of years portions of the nation have been plagued with seasonal shortages of freight cars in which to ship goods.” 322 F. Supp. 725, 726 (MD Fla. 1971). Judge Friendly, writing for a three-judge District Court in the Eastern District of New York in the related case of Long Island R. Co. v. United States, 318 F. Supp. 490, 491 (EDNY 1970), described the Commission’s order as “the latest chapter in a long history of freight-car shortages in certain regions and seasons and of attempts to ease them.” Congressional concern for the problem was manifested in the enactment in 1966 of an amendment to §1 (14) (a) of the Interstate Commerce Act, enlarging the Commission’s authority to prescribe per diem charges for the use by one railroad of freight cars owned by another. Pub. L. 89-430, 80 Stat. 168. The Senate Committee on Commerce stated in its report accompanying this legislation:
“Car shortages, which once were confined to the Midwest during harvest seasons, have become increasingly more frequent, more severe, and nationwide in scope as the national freight car supply has plummeted.” S. Rep. No. 386, 89th Cong., 1st Sess., 1-2.
The Commission in 1966 commenced an investigation, Ex parte No. 252, Incentive Per Diem Charges, “to determine whether information presently available warranted the establishment of an incentive element increase, on an interim basis, to apply pending further study and investigation.” 332 I. C. C. 11, 12 (1967). Statements of position were received from the Commission staff and a number of railroads. Hearings were conducted at which witnesses were examined. In October 1967, the Commission rendered a decision discontinuing the earlier proceeding, but announcing a program of further investigation into the general subject.
In December 1967, the Commission initiated the rule-making procedure giving rise to the order that appellees here challenge. It directed Class I and Class II line-haul railroads to compile and report detailed information with respect to freight-car demand and supply at numerous sample stations for selected days of the week during 12 four-week periods, beginning January 29, 1968.
Some of the affected railroads voiced questions about the proposed study or requested modification in the study procedures outlined by the Commission in its notice of proposed rulemaking. In response to petitions setting forth these carriers’ views, the Commission staff held an informal conference in April 1968, at which the objections and proposed modifications were discussed. Twenty railroads, including appellee Seaboard, were represented at this conference, at which the Commission’s staff sought to answer questions about reporting methods to accommodate individual circumstances of particular railroads. The conference adjourned on a note that undoubtedly left the impression that hearings would be held at some future date. A detailed report of the conference was sent to all parties to the proceeding before the Commission.
The results of the information thus collected were analyzed and presented to Congress'by the Commission during a hearing before the Subcommittee on Surface Transportation of the Senate Committee on Commerce in May 1969. Members of the Subcommittee expressed dissatisfaction with the Commission’s slow pace in exercising the authority that had been conferred upon it by the 1966 Amendments to the Interstate Commerce Act. Judge Simpson in his opinion for the District Court said:
“Members of the Senate Subcommittee on Surface Transportation expressed considerable dissatisfaction with the Commission’s apparent inability to take effective steps toward eliminating the national shortage of freight cars. Comments were general that the Commission was conducting too many hearings and taking too little action. Senators pressed for more action and less talk, but Commission counsel expressed doubt respecting the Commission’s statutory power to act without additional hearings.” 322 F. Supp., at 727.
Judge Friendly, describing the same event in Long Island R. Co. v. United States, supra, said:
“To say that the presentation was not received with enthusiasm would be a considerable understatement. Senators voiced displeasure at the Commission’s long delay at taking action under the 1966 amendment, engaged in some (merriment over what was regarded as an unintelligible discussion of methodology . . . and expressed doubt about the need for a hearing .... But the Commission’s general counsel insisted that a hearing was needed . . . and the Chairman of the Commission agreed . . . .” 318 F. Supp., at 494.
The Commission, now apparently imbued with a new sense of mission, issued in December 1969 an interim report announcing its tentative decision to adopt incentive per diem charges on standard boxcars based on the information compiled by the railroads. The substantive decision reached by the Commission was that so-called “incentive” per diem charges should be paid by any railroad using on its lines a standard boxcar owned by another railroad. Before the enactment of the 1966 amendment to the Interstate Commerce Act, it was generally thought that the Commission’s authority to fix per diem payments for freight car use was limited to setting an amount that reflected fair return on investment for the owning railroad, without any regard being had for the desirability of prompt return to the owning line or for the encouragement of additional purchases of freight cars by the railroads as a method of investing capital. The Commission concluded, however, that in view of the 1966 amendment it could impose additional “incentive” per diem charges to spur prompt return of existing cars and to make acquisition of new cars financially attractive to the railroads. It did so by means of a proposed schedule that established such charges on an across-the-board basis for all common carriers by railroads subject to the Interstate Commerce Act. Embodied in the report was a proposed rule adopting the Commission’s tentative conclusions and a notice to the railroads to file statements of position within 60 days, couched in the following language:
“That verified statements of facts, briefs, and statements of position respecting the tentative conclusions reached in the said interim report, the rules and regulations proposed in the appendix to this order, and any other pertinent matter, are hereby invited to be submitted pursuant to the filing schedule set forth below by an interested person whether or not such person is already a party to this proceeding.
“That any party requesting oral hearing shall set forth with specificity the need therefor and the evidence to be adduced.” 337 I. C. C. 183, 213.
Both appellee railroads filed statements objecting to the Commission’s proposal and requesting an oral hearing, as did numerous other railroads. In April 1970, the Commission, without having held further “hearings,” issued a supplemental report making some modifications in the tentative conclusions earlier reached, but overruling in toto the requests of appellees.
The District Court held that in so doing the Commission violated § 556 (d) of the Administrative Procedure Act, and it was on this basis that it set aside the order of the Commission.
II. Applicability op Administrative Procedure Act
In United States v. Allegheny-Ludlum Steel Corp., supra, we held that the language of § 1 (14) (a) of the Interstate Commerce Act authorizing the Commission to act “after hearing” was not the equivalent of a requirement that a rule be made “on the record after opportunity for an agency hearing” as the latter term is used in § 553 (c) of the Administrative Procedure Act. Since the 1966 amendment to § 1 (14) (a), under which the Commission was here proceeding, does not by its terms add to the hearing requirement contained in the earlier language, the same result should obtain here unless that amendment contains language that is tantamount to such a requirement. Appellees contend that such language is found in the provisions of that Act requiring that:
“[T]he Commission shall give consideration to the national level of ownership of such type of freight car and to other factors affecting the adequacy of the national freight car supply, and shall, on the basis of such consideration, determine whether compensation should be computed . . .
While this language is undoubtedly a mandate to the Commission to consider the factors there set forth in reaching any conclusion as to imposition of per diem incentive charges, it adds to the hearing requirements of the section neither expressly nor by implication. We know of no reason to think that an administrative agency in reaching a decision cannot accord consideration to factors such as those set forth in the 1966 amendment by means other than a trial-type hearing or the presentation of oral argument by the affected parties. Congress by that amendment specified necessary components of the ultimate decision, but it did not specify the method by which the Commission should acquire information about those components.
Both of the district courts that reviewed this order of the Commission concluded that its proceedings were governed by the stricter requirements of §§ 556 and 557 of the Administrative Procedure Act, rather than by the provisions of § 553 alone. The conclusion of the District Court for the Middle District of Florida, which we here review, was based on the assumption that the language in § 1 (14) (a) of the Interstate Commerce Act requiring rulemaking under that section to be done “after hearing” was the equivalent of a statutory requirement that the rule “be made on the record after opportunity for an agency hearing.” Such an assumption is inconsistent with our decision in Allegheny-Ludlum, supra.
The District Court for the Eastern District of New York reached the same conclusion by a somewhat different line of reasoning. That court felt that because §1(14) (a) of the Interstate Commerce Act had required a “hearing,” and because that section was originally enacted in 1917, Congress was probably thinking in terms of a “hearing” such as that described in the opinion of this Court in the roughly contemporaneous case of ICC v. Louisville & Nashville R. Co., 227 U. S. 88, 93 (1913). The ingredients of the “hearing” were there said to be that “[a] 11 parties must be fully apprised of the evidence submitted or to be considered, and must be given opportunity to cross-examine witnesses, to inspect documents and to offer evidence in explanation or rebuttal.” Combining this view of congressional understanding of the term “hearing” with comments by the Chairman of the Commission at the time of the adoption of the 1966 legislation regarding the necessity for “hearings,” that court concluded that Congress had, in effect, required that these proceedings be “on the record after opportunity for an agency hearing” within the meaning of § 553 (c) of the Administrative Procedure Act.
Insofar as this conclusion is grounded on the belief that the language “after hearing” of § 1 (14) (a), without more, would trigger the applicability of §§ 556 and 557, it, too, is contrary to our decision in Allegheny-Ludlum, supra. The District Court observed that it was “rather hard to believe that the last sentence of § 553 (c) was directed only to the few legislative sports where the words ‘on the record’ or their equivalent had found their way into the statute book.” 318 F. Supp., at 496. This is, however, the language which Congress used, and since there are statutes on the books that do use these very words, see, e. g., the Fulbright Amendment to the Walsh-Healey Act, 41 U. S. C. § 43a, and 21 U. S. C. §371 (e)(3), the regulations provision of the Food and Drug Act, adherence to that language cannot be said to render the provision nugatory or ineffectual. We recognized in Allegheny-Ludlum that the actual words “on the record” and “after . . . hearing” used in § 553 were not words of art, and that other statutory language having the same meaning could trigger the provisions of §§ 556 and 557 in rulemaking proceedings. But we adhere to our conclusion, expressed in that case, that the phrase “after hearing” in § 1 (14) (a) of the Interstate Commerce Act does not have such an effect.
III. “Hearing” Requirement op § 1 (14) (a) op the Interstate Commerce Act
Inextricably intertwined with the hearing requirement of the Administrative Procedure Act in this case is the meaning to be given to the language “after hearing” in § 1 (14) (a) of the Interstate Commerce Act. Appellees, both here and in the court below, contend that the Commission procedure here fell short of that mandated by the “hearing” requirement of § 1 (14)(a), even though it may have satisfied § 553 of the Administrative Procedure Act. The Administrative Procedure Act states that none of its provisions “limit or repeal additional requirements imposed by statute or otherwise recognized by law.” 5 U. S. C. § 559. Thus, even though the Commission was not required to comply with §§ 556 and 557 of that Act, it was required to accord the “hearing^ specified in § 1 (14) (a) of the Interstate Commerce Act. Though the District Court did not pass on this contention, it is so closely related to the claim based on the Administrative Procedure Act that we proceed to decide it now.
If we were to agree with the reasoning of the District Court for the Eastern District of New York with respect to the type of hearing required by the Interstate Commerce Act, the Commission’s action might well violate those requirements, even though it was consistent with the requirements of the Administrative Procedure Act.
The term “hearing” in its legal context undoubtedly has a host of meanings. Its meaning undoubtedly will vary, depending on whether it is used in the context of a rulemaking-type proceeding or in the context of a proceeding devoted to the adjudication of particular disputed facts. It is by no means apparent what the drafters of the Esch Car Service Act of 1917, 40 Stat. 101, which became the first part of § 1 (14) (a) of the Interstate Commerce Act, meant by the term. Such an intent would surely be an ephemeral one if, indeed, Congress in 1917 had in mind anything more specific than the language it actually used, for none of the parties refer to any legislative history that would shed light on the intended meaning of the words “after hearing.” What is apparent, though, is that the term was used in granting authority to the Commission to make rules and regulations of a prospective nature.
Appellees refer us to testimony of the Chairman of the Commission to the effect that if the added authority ultimately contained in the 1966 amendment were enacted, the Commission would proceed with “great caution” in imposing incentive per diem rates, and to statements of both Commission personnel and Members of Congress as to the necessity for a “hearing” before Commission action. Certainly, the lapse of time of more than three years between the enactment of the 1966 amendment and the Commission’s issuance of its tentative conclusions cannot be said to evidence any lack of caution on the part of that body. Nor do generalized references to the necessity for a hearing advance our inquiry, since the statute by its terms requires a “hearing”; the more precise inquiry of whether the hearing requirements necessarily include submission of oral testimony, cross-examination, or oral arguments is not resolved by such comments as these.
Under these circumstances, confronted with a grant of substantive authority made after the Administrative Procedure Act was enacted, we think that reference to that Act, in which Congress devoted itself exclusively to questions such as the nature and scope of hearings, is a satisfactory basis for determining what is meant by the term “hearing” used in another statute. Turning to that Act, we are convinced that the term “hearing” as used therein does not necessarily embrace either the right to present evidence orally and to cross-examine opposing witnesses, or the right to present oral argument to the agency’s decisionmaker.
Section 553 excepts from its requirements rulemaking devoted to “interpretative rules, general statements 'of policy, or rules of agency organization, procedure, or practice,” and rulemaking “when the agency for good cause finds . . . that notice and public procedure thereon are impracticable, unnecessary, or contrary to the public interest.” This exception does not apply, however, “when notice or hearing is required by statute”; in those cases, even though interpretative rulemaking be involved, the requirements of § 553 apply. But since these require-merits themselves do not mandate any oral presentation, see Allegheny-Ludlum, supra, it cannot be doubted that a statute that requires a “hearing” prior to rulemaking may in some circumstances be satisfied by procedures that meet only the standards of § 553. The Court’s opinion in FPC v. Texaco Inc., 377 U. S. 33 (1964), supports such a broad definition of the term “hearing.”
Similarly, even where the statute requires that the rulemaking procedure take place “on the record after opportunity for an agency hearing,” thus triggering the applicability of § 556, subsection (d) provides that the agency may proceed by the submission of all or part of the evidence in written form if a party will not be “prejudiced thereby.” Again, the Act makes it plain that a specific statutory mandate that the proceedings take place on the record after hearing may be satisfied in some circumstances by evidentiary submission in written form only.
We think this treatment of the term “hearing” in the Administrative Procedure Act affords a sufficient basis for concluding that the requirement of a “hearing” contained in § 1 (14) (a), in a situation where the Commission was acting under the 1966 statutory rulemaking authority that Congress had conferred upon it, did not by its own force require the Commission either to hear oral testimony, to permit cross-examination of Commission witnesses, or to hear oral argument. Here, the Commission promulgated a tentative draft of an order, and accorded all interested parties 60 days in which to file statements of position, submissions of evidence, and other relevant observations. The parties had fair notice of exactly what the Commission proposed to do, and were given an opportunity to comment, to object, or to make some other form of written submission. The final order of the Commission indicates that it gave consideration to the statements of the two appellees here. Given the “open-ended” nature of the proceedings, and the Commission’s announced willingness to consider proposals for modification after operating experience had been acquired, we think the hearing requirement of § 1 (14) (a) of the Act was met.
Appellee railroads cite a number of our previous decisions dealing in some manner with the right to a hearing in an administrative proceeding. Although appellees have asserted no claim of constitutional deprivation in this proceeding, some of the cases they rely upon expressly speak in constitutional terms, while others are less than clear as to whether they depend upon the Due Process Clause of the Fifth and Fourteenth Amendments to the Constitution, or upon generalized principles of administrative law formulated prior to the adoption of the Administrative Procedure Act.
Morgan v. United States, 304 U. S. 1 (1938), is cited in support of appellees’ contention that the Commission’s proceedings were fatally deficient. That opinion describes the proceedings there involved as “quasi-judicial,” id., at 14, and thus presumably distinct from a rulemaking proceeding such as that engaged in by the Commission here. But since the order of the Secretary of Agriculture there challenged did involve a form of ratemaking, the case bears enough resemblance to the facts of this case to warrant further examination of appellees’ contention. The administrative procedure in Morgan was held to be defective primarily because the persons who were to be affected by the Secretary’s order were found not to have been adequately apprised of what the Secretary proposed to do prior to the time that he actually did it. Illustrative of the Court’s reasoning is the following passage from the opinion:
“The right to a hearing embraces not only the right to present evidence but also a reasonable opportunity to know the claims of the opposing party and to meet them. The right to submit argument implies that opportunity; otherwise the right may be but a barren one. Those who are brought into contest with the Government in a quasi-judicial proceeding aimed at the control of their activities are entitled to be fairly advised of what the Government proposes and to be heard upon its proposals before it issues its final command.” Id., at 18-19.
The proceedings before the Secretary of Agriculture had been initiated by a notice of inquiry into the reasonableness of the rates in question, and the individuals being regulated suffered throughout the proceeding from its essential formlessness. The Court concluded that this formlessness denied the individuals subject to regulation .-.the “full hearing” that the statute had provided.
Assuming, arguendo, that the statutory term “full hearing” does not differ significantly from the hearing requirement of §1(14) (a), we do not believe that the proceedings of the Interstate Commerce Commission before us suffer from the defect found to be fatal in Morgan. Though the initial notice of the proceeding by no means set out in detail what the Commission proposed to do, its tentative conclusions and order of December 1969, could scarcely have been more explicit or detailed. All interested parties were given 60 days following the issuance of these tentative findings and order in which to make appropriate objections. Appellees were “fairly advised” of exactly what the Commission proposed to do sufficiently in advance of the entry of the final order to give them adequate time to formulate and to present objections to the Commission’s proposal. Morgan, therefore, does not aid appellees.
ICC v. Louisville & Nashville R. Co., 227 U. S. 88 (1913), involved what the Court there described as a “quasi-judicial” proceeding of a quite different nature from the one we review here. The provisions of the Interstate Commerce Act, 24 Stat. 379, as amended, and of the Hepburn Act, 34 Stat. 584, in effect at the time that case was decided, left to the railroad carriers the “primary right to make rates,” 227 U. S., at 92, but granted to the Commission the authority to set them aside, if after, hearing, they were shown to be unreasonable. The proceeding before the Commission in that case had been instituted by the New Orleans Board of Trade complaint that certain class and commodity rates charged by the Louisville & Nashville Railroad from New Orleans to other points were unfair, unreasonable, and discriminatory. 227 U. S., at 90. The type of proceeding there, in which the Commission adjudicated a complaint by a shipper that specified rates set by a carrier were unreasonable, was sufficiently different from the nationwide incentive payments ordered to be made by all railroads in this proceeding so as to make the Louisville Nashville opinion inapplicable in the case presently before us.
The basic distinction between rulemaking and adjudication is illustrated by this Court’s treatment of two related cases under the Due Process Clause of the Fourteenth Amendment. In Londoner v. Denver, cited in oral argument by appellees, 210 U. S. 373 (1908), the Court held that due process had not been accorded a landowner who objected to the amount assessed against his land as its share of the benefit resulting from the paving of a street. Local procedure had accorded him the right to file a written complaint and objection, but not to be heard orally. This Court held that due process of law required that he “have the right to support his allegations by argument however brief, and, if need be, by proof, however informal.” Id., at 386. But in the later case of Bi-Metallic Investment Co. v. State Board of Equalization, 239 U. S. 441 (1915), the Court held that no hearing at all was constitutionally required prior to a decision by state tax officers in Colorado to increase the valuation of all taxable property in Denver by a substantial percentage. The Court distinguished Londoner by stating that there a small number of persons “were exceptionally affected, in each case upon individual grounds.” Id., at 446.
Later decisions have continued to observe the distinction adverted to in Bi-Metallic Investment Co., supra. In Ohio Bell Telephone Co. v. Public Utilities Comm’n, 301 U. S. 292, 304-305 (1937), the Court noted the fact that the administrative proceeding there involved was designed to require the utility to refund previously collected rate charges. The Court held that in such a proceeding the agency could not, consistently with due process, act on the basis of undisclosed evidence that was never made a part of the record before the agency. The Case is thus more akin to Louisville & Nashville R. Co., supra, than it is to this case. FCC v. WJR, 337 U. S. 265 (1949), established that there was no across-the-board constitutional right to oral argument in every administrative proceeding regardless of its nature. While the line dividing them may not always be a bright one, these decisions represent a recognized distinction in administrative law between proceedings for the purpose of promulgating policy-type rules or standards, on the one hand, and proceedings designed to adjudicate disputed facts in particular cases on the other.
Here, the incentive payments proposed by the Commission in its tentative order, and later adopted in its final order, were applicable across the board to all of the common carriers by railroad subject to the Interstate Commerce Act. No effort was made to single out any particular railroad for special consideration based on its own peculiar circumstances. Indeed, one of the objections of appellee Florida East Coast was that it and other terminating carriers should have been treated differently from the generality of the railroads. But the fact that the order may in its effects have been thought more disadvantageous by some railroads than by others does not change its generalized nature. Though the Commission obviously relied on factual inferences as a basis for its order, the source of these factual inferences was apparent to anyone who read the order of December 1969. The factual inferences were used in the formulation of a basically legislative-type judgment, for prospective application only, rather than in adjudicating a particular set of disputed facts.
The Commission’s procedure satisfied both the provisions of §1(14) (a) of the Interstate Commerce Act and of the Administrative Procedure Act, and were not inconsistent with prior decisions of this Court. We, therefore, reverse the judgment of the District Court, and remand the case so that it may consider those contentions of the parties that are not disposed of by this opinion.
It is so ordered.
Me. Justice Powell took no part in the consideration or decision of this case.
Section. 1 (14) (a) provides:
“The Commission may, after hearing, on a complaint or upon its own initiative without complaint, establish reasonable rules, regulations, and practices with respect to ear service by common carriers by railroad subject to this chapter, including the compensation to be paid and other terms of any contract, agreement, or arrangement for the use of any locomotive, car, or other vehicle not owned by the carrier using it (and whether or not owned by another carrier), and the penalties or other sanctions for nonobservance of such rules, regulations, or practices. In fixing such compensation to be paid for the use of any type of freight car, the Commission shall give consideration to the national level of ownership of such type of freight car and to other factors affecting the adequacy of the national freight car supply, and shall, on the basis of such consideration, determine whether compensation should be computed solely on the basis of elements of ownership expense involved in owning and maintaining such type of freight car, including a fair return on value, or whether such compensation should be increased by such incentive element or elements of compensation as in the Commission’s judgment will provide just and reasonable compensation to freight car owners, contribute to sound car service practices (including efficient utilization and distribution of cars), and encourage the acquisition and maintenance of a car supply adequate to meet the needs of commerce and the national defense. The Commission shall not make any incentive element applicable to any type of freight car the supply of which the Commission finds to be adequate and may exempt from the compensation to be paid by any group of carriers such incentive element or elements if the Commission finds it to be in the national interest.”

“(b) When the agency did not preside at the reception of the evidence, the presiding employee or, in cases not subject to section 554 (d) of this title, an employee qualified to preside at hearings pursuant to section 556 of this title, shall initially decide the case unless the agency requires, either in specific cases or by general rule, the entire record to be certified to it for decision. When the presiding employee makes an initial decision, that decision then becomes the decision of the agency without further proceedings unless there is an appeal to, or review on motion of, the agency within time provided by rule. On appeal from or review of the initial decision, the agency has all the powers which it would have in making the initial decision except as it may limit the issues on notice or by rule. When the agency makes the decision without having presided at the reception of the evidence, the presiding employee or an employee qualified to preside at hearings pursuant to section 556 of this title shall first recommend a decision, except that in rule making or determining applications for initial licenses—
“(1) instead thereof the agency may issue a tentative decision or one of its responsible employees may recommend a decision; or
“ (2) this procedure may be omitted in a case in which the agency finds on the record that due and timely execution of its functions imperatively and unavoidably so requires.
“ (c) Before a recommended, initial, or tentative decision, or a decision on agency review of the decision of subordinate employees, the parties are entitled to a reasonable opportunity to submit for the consideration of the employees participating in the decisions—
“(1) proposed findings and conclusions; or
“(2) exceptions to the decisions or recommended decisions of subordinate employees or to tentative agency decisions; and
“(3) supporting reasons for the exceptions or proposed findings or conclusions.
“The record shall show the ruling on each finding, conclusion, or exception presented. All decisions, including initial, recommended, and tentative decisions, are a part of the record and shall include a statement of—
“(A) findings and conclusions, and the reasons or basis therefor, on all the material issues of fact, law, or discretion presented on the record; and
“(B) the appropriate rule, order, sanction, relief, or denial thereof.”
The Court of Appeals for the Ninth Circuit reached a result similar to that which we reach, in Pacific Coast European Conference v. United States, 350 F. 2d 197 (1965). Construing the authority of the Federal Maritime Commission under § 14b of the Shipping Act, 1916, as amended, 46 U. S. C. § 813a, that court observed that “[t]he authority of the Commission to permit such contracts was limited by requiring that the contracts in eight specified respects meet the congressional judgment as to what they should include.” 350 F. 2d, at 201. Notwithstanding these explicit directions that particular factors be considered by the Commission in reaching its decision, the court held that the statute’s requirements of “notice and hearing” were not sufficient to bring into play the provisions of §§ 556 and 557 of the Administrative Procedure Act.
Both district court opinions were handed down before our decision in United States v. Allegheny-Ludlum, Steel Corp., 406 U. S. 742 (1972), and it appears from the record before us that the Government in those courts did not really contest the proposition that the Commission’s proceedings were governed by the stricter standards of §§ 556 and 557.
The dissenting opinion of Mr. Justice Douglas relies in part on indications by the Commission that it proposed to apply the more stringent standards of §§ 556 and 557 of the Administrative Procedure Act to these proceedings. This Act is not legislation that the Interstate Commerce Commission, or any other single agency, has primary responsibility for administering. An agency interpretation involving, at least in part, the provisions of that Act does not carry the weight, in ascertaining the intent of Congress, that an interpretation by an agency “charged with the responsibility” of administering a particular statute does. See United States v. American Trucking Assns., 310 U. S. 534 (1940); Norwegian Nitrogen Products Co. v. United States, 288 U. S. 294 (1933). Moreover, since any agency is free under the Act to accord litigants appearing before it more procedural rights than the Act requires, the fact that an agency may choose to proceed under §§ 556 and 557 does not carry the necessary implication that the agency felt it was required to do so.
See 1 K. Davis, Administrative Law Treatise, §6.05 (1958).
The Interstate Commerce Act was amended in May 1966; the 1946 Administrative Procedure Act was repealed by Act of Sept. 6, 1966, 80 Stat. 378, which revised, codified, and enacted Title 5 of the United States Code, but the section detailing the procedures to be used in rulemaking is substantially similar to the original provision in the 1946 Administrative Procedure Act. See § 4 (b), 60 Stat. 238.
This same language was cited with approval by the Court in Willner v. Committee on Character, 373 U. S. 96, 105 (1963), in which it was held that an applicant for admission to the bar could not be denied such admission on the basis of ex parte statements of others whom he had not been afforded an opportunity to cross-examine.
What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.
