delivered the opinion of the Court.

Three cases, consolidated for hearing in the court below, raise the issue of the effect of the Freedom of Information Act (FOIA), 5 U. S. C. § 552, upon proceedings pending under the Renegotiation Act of 1951, c. 15, 65 Stat. 7, as amended, 50 U. S. C. App. § 1211 et seg. In particular, they concern the jurisdiction of a federal district court to enjoin the renegotiation process until an FOIA claim is resolved.

I

The three respondents, Bannercraft Clothing Company, Inc., Astro Communication Laboratory, a division of Aiken Industries, Inc., and David B. Lilly Co., Inc., successor to Delaware Fastener Corporation, all possessed national defense contracts with a “Department” of the United States, as defined in § 103 (a) of the Renegotiation Act, 50 U. S. C. App. § 1213 (a). These agreements, therefore, under § 102 of that Act, 50 U. S. C. App. § 1212, were subject to renegotiation.

A. Bannercraft. In 1966 and 1967, this respondent manufactured uniforms at a plant in Philadelphia. Its fiscal year was the calendar year. Because most of its production was subject to renegotiation, the company, for each of the two years, timely filed with the Renegotiation Board the financial statement required under § 105 (e)(1) of the Act, 50 U. S. C. App. § 1215 (e)(1). Rep*4resentatives of the Eastern Regional Renegotiation Board then reviewed Bannercraft’s operations and conferred with its president. On February 20, 1970, the Regional Board, by letter, advised the contractor that it was recommending that Bannercraft in 1967 had realized excessive profits in the amount of $1,400,000, subject to the usual adjustment for state taxes measured by income and for any tax credit to which the contractor was entitled under § 1481 of the Internal Revenue Code of 1954, 26 U. S. C. § 1481.1

Bannercraft promptly requested that it be furnished, pursuant to 32 CFR § 1477.3 (1970),2 with a “written summary of the facts and reasons” upon which the determination was based. It asserted, however, that “it is not possible to state [as the Regulation’s proviso required] whether all relevant evidence has been submitted since we have never had in writing the basis upon which you made this determination.” The Regional Board replied that because “the statement required by the regulation” was not submitted, “your request for a summary is defective.”

Bannercraft’s response was that it had “submitted all of the evidence which it believes to be relevant to the *5renegotiation proceedings,” but that this was “without prejudice to an opportunity to offer evidence on the issues disclosed by the [Regional Board's] Summary of Facts and Reasons” and that the required statement was “somewhat meaningless when we do not have a written statement of the issue upon which you have made your finding.”

On March 16, Bannercraft, pursuant to the FOIA, made a written request of the Renegotiation Board that six categories of documents be produced.3 No response to this request was forthcoming.

In late April, the Board, by letters, notified Banner-craft of its determinations that the contractor had realized excessive profits in the amount of $75,000 for 1966 (the same figure determined by the Regional Board) and *6$1,450,000 for 1967 (an increase of $50,000 over the Regional Board's determination).

Bannercraft then went to court. On May 1, it filed a complaint against the Board in the United States District Court for the District of Columbia, praying that the Board be enjoined from withholding the documents requested and from conducting any further renegotiation proceedings with Bannercraft for 1966 and 1967 until the documents were produced. The Board opposed the application for temporary relief and moved to dismiss. Judge Smith issued a temporary restraining order and, thereafter, a preliminary injunction, each without opinion, and stayed further Board proceedings.

In May, the Board issued a Statement of Facts and Reasons for Bannercraft’s years 1966 and 1967. Ban-nercraft then made a further request for documents related to the factual basis for the Board’s conclusions reflected in the Statement. In July, the Board responded. It produced some documents and, with respect to others, claimed exemption under 5 U. S. C. § 552 (b) 4 or asserted that the information sought was not covered by the Act.5

*7On August 4, the Board moved to dissolve the preliminary injunction. It took the position that its response to Bannercraft’s requests fulfilled its obligations under the FOIA. The District Court denied the motion. The Board then appealed.

B. Astro. This respondent’s factual case is essentially the same as Bannercraft’s. The year at issue is the fiscal year ended September 30, 1967. Astro, pursuant to the FOIA, requested production by the Board of five categories of material.6 At a conference held on May 12, 1970, Astro was advised that the Board had made a tentative determination of excessive profits for the year in the amount of $225,000. In July, the Board denied Astro’s FOIA request.

*8On August 12, Astro filed its complaint against the Board in the United States District Court for the District of Columbia. It prayed for relief similar to that sought by Bannercraft. Judge Pratt enjoined the Board from continuing renegotiation proceedings with Astro. The court also ordered the Board to allow Astro, within 30 days, to inspect and obtain copies of all documents requested by Astro that the Board had no objection to turning over, and to submit to the court, in camera, all documents the Board objected to producing, with a statement of reasons for each objection. The Board appealed.

C. Lilly. This respondent’s case is similar to the other two. In June 1970, Lilly and its predecessor in interest, Delaware Fastener Corporation, were advised by their renegotiator that he had made determinations of excessive profits for 1967 for Lilly in the amount of $200,000 and for Fastener in the amount of $500,000.7 On June 29, the two corporations asked the Board to furnish certain categories of information.8

No response was immediately forthcoming from the Board. On July 9, Lilly filed its complaint against the Board in the United States District Court for the Dis*9trict of Columbia, praying for an order compelling the Board to produce the documents demanded and restraining the Board from acting and, in particular, from requiring the contractors to elect a procedure until the documents had been produced and the contractors had been given a reasonable time to study them. Thereafter, the Board denied the request for information.

On July 31, Judge Jones issued an order temporarily restraining the Board from continuing renegotiation with Lilly and Delaware. Subsequently, the Board moved to dismiss the complaint or, in the alternative, for summary judgment. On September 1, a preliminary injunction was issued. The Board appealed.

The three appeals were consolidated and heard together in the United States Court of Appeals for the District of Columbia Circuit. The Court of Appeals, one judge dissenting, affirmed all three decisions. 151 U. S. App. D. C. 174, 466 F. 2d 345 (1972). It held that the District Court possessed jurisdiction under the FOIA to enjoin administrative proceedings before the Board and to order the production of appropriate documents. It concluded that, “although it is undeniably true that Congress was principally interested in opening administrative processes to the scrutiny of the press and general public” when it enacted the FOIA, “Congress was also troubled by the plight of those forced to litigate with agencies on the basis of secret laws or incomplete information.” Id., at 181, 466 F. 2d, at 352. The court then described this latter congressional concern as a “subsidiary statutory purpose,” citing excerpts from S. Rep. No. 813, 89th Cong., 1st Sess., 7 (1965), and from H. R. Rep. No. 1497, 89th Cong., 2d Sess., 8 (1966), and also citing 5 U. S. C. § 552 (a)(2). See infra, at 12 n. 9. It reasoned that, despite “the fact that the Act nowhere in terms authorizes . . . injunctions” against agency proceedings, in enacting the statute Congress intended to confer broad *10equitable jurisdiction upon the district courts, and that “temporary stays of pending administrative procedures may be necessary on occasion to enforce the policy” of the FOIA. 151 U. S. App. D. C., at 181-183, 466 F. 2d, at 352-354.

The court then turned to the exhaustion-of-administrative-remedies question. It observed that there is no general rule that it is always improper for a court to interfere with pending administrative proceedings, citing McKart v. United States, 395 U. S. 185, 193 (1969). It concluded that “when the purposes of the doctrine are individually measured against the facts of these cases, it is plain that no legitimate judicial policy would be served by depriving these appellees of the relief they seek.” 151 U. S. App. D. C., at 184, 466 F. 2d, at 355. In effect, the court reasoned that contractors need exhaust only their administrative remedies under the FOIA, and not their administrative remedies under the Renegotiation Act, as a condition precedent to requesting injunctive relief against renegotiation proceedings. The court found the contractors’ remedies before the Board and de novo proceedings in the Court of Claims inadequate to prevent irreparable harm.

The dissenting judge began with the accepted proposition that federal courts have only limited jurisdiction and stated that the majority’s observation, to the effect that the “existence of present need for judicial intervention does have a bearing on both jurisdiction and exhaustion,” is “an error bordering on constitutional dimensions,” for the appellees’ need “is wholly irrelevant to determination of the jurisdiction of the District Courts in these cases.” Id., at 191, 466 F. 2d, at 362.

The dissent then turned to the principle that where a statute creates a right and provides a special remedy, that remedy is exclusive. Thus, in the FOIA, Congress *11gave the general public an express right of access to all Federal Government information not within the exempted categories. This right was enforceable by “the specific, narrow, remedies of an injunction against withholding agency records and an affirmative order to produce such records improperly withheld.” Ibid. The dissent concluded that no jurisdiction to grant any other remedy was conferred by Congress and that the District Court, therefore, was without jurisdiction to enjoin the proceedings before the Renegotiation Board. Nothing in the congressional reports cited by the majority justified its contrary conclusion. The dissent further concluded that there was no suggestion that Congress had any concern with litigants before the administrative agencies, and that what they were concerned with was to make information available “to any member of the public without requiring any showing of need therefor.” Id., at 192, 466 F. 2d, at 363.

The dissent also was at odds with the majority’s disposition of the exhaustion issue. It asserted that the majority seriously misconstrued the intended functioning of the Renegotiation Board’s procedures, namely, that controlled access to information concerning the Government’s position plays a significant role in the administrative process; that interruption of the administrative proceedings totally destroys the balance of negotiating strength; and that the attempt to enjoin the ongoing negotiations was really not a request for relief under the FOIA but was a challenge to the Board’s procedures themselves. Id., at 194-195, 466 F. 2d, at 365-366.

We granted certiorari, 410 U. S. 907 (1973), because of the importance of the issue of the impact of the FOIA upon long-established procedures of the Renegotiation Board.

*12II

Before considering the issue of the District Court’s jurisdiction to enjoin a proceeding pending in the Renegotiation Board, it is helpful to review the provisions of the FOIA and of the Renegotiation Act of 1951:

A. The FOIA. This statute, 5 U. S. C. § 552, was enacted in 1966, 80 Stat. 383, as a revision of § 3 of the Administrative Procedure Act, 5 U. S. C. § 1002 (1964 ed.). S. Rep. No. 813, 89th Cong., 1st Sess., 3-4 (1965); H. R, Rep. No. 1497, 89th Cong., 2d Sess., 1-6 (1966). It was amended by Pub. L. 90-23, adopted June 5, 1967, 81 Stat. 54. '

Section 552 (a) states, “Each agency shall make available to the public” certain information of enumerated categories. This covers virtually all information not specifically exempted by § 552 (b). Section 552 (a) (2) 9 provides the sanction that a “final order, opinion, statement of policy, interpretation, or staff manual or instruc*13tion” may not be relied upon as precedent by the agency against a party unless “it has been indexed and either made available or published,” or unless a party has “actual and timely notice of the terms thereof.” Section 552 (a) (3) specifically vests the District Court with jurisdiction “to enjoin the agency from withholding agency records and to order the production of any agency records improperly withheld.” It places the burden on the agency to sustain its action; it empowers the District Court to punish the responsible employee for contempt in the event of noncompliance; and it provides that the FOIA suit generally is to take precedence on the court's docket and is to be expedited on the calendar.10

B. The Renegotiation Act of 1951.11 This statute, 50 U. S. C. App. §§ 1211-1233, enacted shortly after the close of World War II and at the height of the Korean conflict, recites that Congress had made available “extensive funds” for the execution of the national defense program and that “sound execution” of the program requires “the elimination of excessive profits from contracts made with the United States, and from related subcontracts.” § 101, 50 U. S. C. App. § 1211. The Renegotiation *14Board is established as an independent agency in the Executive Branch to accomplish this objective. § 107, 50 U. S. C. App. § 1217 (a). The Board’s functions are excluded from the operation of the Administrative Procedure Act (5 U. S. C. § 551 et seq., and § 701 et seq.) except the public information section thereof (5 U. S. C. § 552). § 111, 50 U. S. C. App. § 1221.

The Board operates primarily by informal negotiation with the contractor and not by formal hearing. It is directed to “endeavor to make an agreement with the contractor . . . with respect to the elimination of excessive profits.” § 105 (a), 50 U. S. C. App. § 1215 (a). The contractor subject to the Act must file, for its fiscal year, a detailed financial statement. §105 (e)(1), 50 U. S. C. App. § 1215 (e)(1). On the basis of this statement an initial determination of excessive profits is made. From the date of filing of the statement, the Board has one year to commence proceedings12 and, with stated exceptions, the renegotiation is to be completed within two years following its commencement or “all liabilities of the contractor ... for excessive profits with respect to which such proceeding was commenced shall thereupon be discharged.” 13 § 105 (c), 50 U. S. C. App. § 1215 (c).

If the Board and the contractor do not agree, the Board by order determines the excessive profits. § 105 (a), 50 U. S. C. App. § 1215 (a). At the request of the contractor, the Board shall furnish it “with a statement of such determination, of the facts used as a basis *15therefor, and of its reasons for such determination.” Ibid. The contractor then may initiate a de novo proceeding in the Court of Claims,14 which has exclusive jurisdiction to determine the contractor’s excessive profits. § 108, 50 U. S. C. App. § 1218 (1970 ed., Supp. II). The action “shall not be treated as a proceeding to review the determination of the Board,” ibid., and the Board’s statement “shall not be used in the Court of Claims as proof of the facts or conclusions stated therein,” § 105 (a), 50 U. S. C. App. § 1215 (a) (1970 ed., Supp. II).

The renegotiation process itself is initiated by notice to the contractor and by assignment of the contractor’s report to the appropriate Regional Board. 32 CFR § 1472.2 (1972).15 Personnel of the Regional Board then prepare a “Report of Renegotiation” which includes a “recommendation with respect to the amount, if any, of excessive profits for the fiscal year under review.” 32 CFR § 1472.3 (d). This is only the first of several steps within the agency structure. Thereafter the statement is reviewed, successively, by a panel of the Regional Board, by the Regional Board itself, and finally by the Renegotiation Board. At each level there is consultation with the contractor, the preparation of a report and analysis, and submission to the next higher level of a recommendation as to excessive profits. 32 CFR §§ 1472.3 (d) and (f)-(i), and §§ 1472.4 (b)-(d). At each stage, the contractor is entitled to a statement of the basis for the recommendation. Each level is free to make new findings and no level is bound by the deter*16mination of the level below; the recommended settlement may decrease or increase at each level. Ibid.

Ill

It is clear, we think, that the Renegotiation Board, as an entity, is not exempt from applicable provisions of the FOIA. The Board, of course, is an “independent establishment” in the Executive Branch. § 107 (a) of the Renegotiation Act, 50 U. S. C. App. § 1217 (a). But “agency” is broadly defined to mean “each authority of the Government of the United States,” except the Congress, the courts, territorial governments, the government of the District of Columbia, and, with respect to 5 U. S. C. § 552, certain other specifically described entities and functions. 5 U. S. C. §551 (1). The Renegotiation Board is not among those excepted. Further, the House Committee’s discussion of the requirement of § 552 (a)(2), that an agency’s concurring and dissenting opinions, as well as final opinions, be made available, discloses that a reason for this provision was that “a recent survey indicated that five agencies— including . . . the Renegotiation Board — do not make public the minority views of their members.” H. R. Rep. No; 1497, supra, at 8. Thus, despite its unique operational methods, the Board falls within the definition of “agency” in § 551 (1).16

So to conclude, however, does not provide automatically the answer to the question whether the FOIA authorizes a district court to enjoin Renegotiation Board *17proceedings until the court determines that the contractor is or is not entitled to information it claims under the FOIA.

As to this question, the respondent contractors assert that, although the FOIA does not grant this injunctive power in express terms, the power is to be implied from the court's inherent capacity to provide appropriate equitable relief. The Board, on the other hand, emphasizes that Congress in the Act expressly authorized the court to compel the production of agency records improperly withheld, placed the burden on the agency to sustain its action, and directed precedence on the docket for suits under the Act “over all other causes” and expedition of those suits “in every way.” 5 U. S. C. § 552 (a)(3). The Board then contends that these provisions constitute the exclusive method for enforcing the disclosure requirements of the Act and that any implication of other injunctive power, at the behest of a litigant before the agency, would be inconsistent with the statutory language.

Clearly, as the Court of Appeals held, 151 U. S. App. D. C., at 181, 466 F. 2d, at 352, the Congress “was principally interested in opening administrative processes to the scrutiny of the press and general public when it passed the Information Act.” The Second Circuit has described the Act’s “ultimate purpose” as one “to enable the public to have sufficient information in order to be able, through the electoral process, to make intelligent, informed choices with respect to the nature, scope, and procedure of federal governmental activities” (footnote omitted). Frankel v. SEC, 460 F. 2d 813, 816, cert. denied, 409 U. S. 889 (1972). The Senate Report, too, expressed concern for “an informed electorate.” S. Rep. No. 813, 89th Cong., 1st Sess., 3 (1965).17

*18The FOIA, 5 U. S. C. § 552 (a)(3), explicitly confers jurisdiction18 to grant injunctive relief of a described type, namely, “to enjoin the agency from withholding agency records and to order the production of any agency records improperly withheld from the complainant.” In addition, it provides a specific remedy for noncompliance.

This primary purpose of the FOIA, and this express grant of jurisdiction to enjoin in a specific way, coupled with a limited sanction, might suggest that the Act’s provision for compelled production was intended to be the exclusive enforcement method. It has been held that “where a statute creates a right and provides a special remedy, that remedy is exclusive.” United States v. Babcock, 250 U. S. 328, 331 (1919). And “Congress for reasons of its own decided upon the method for the protection of the 'right’ which it created. It selected the precise machinery and fashioned the tool which it deemed suited to that end.” Switchmen’s Union v. NMB, *19320 U. S. 297, 301 (1943). See National Railroad Passenger Corp. v. National Assn. of Railroad Passengers, 414 U. S. 453, 458 (1974). One therefore may argue, as the Board has argued here, that this is not a situation where “Congress has utilized ... the broad equitable jurisdiction that inheres in courts and where the proposed exercise of that jurisdiction is consistent with the statutory language and policy, the legislative background and the public interest.” Porter v. Warner Holding Co., 328 U. S. 395, 403 (1946).

There is significant authority, however, that points to the opposite conclusion. Porter itself, although recognizing the kind of situation to which Babcock is applicable, 328 U. S., at 403, upheld broad equitable power in the District Court under a statute authorizing the court to grant injunctive and restraining relief “or other order,” and did so, not only because of the presence of the “other order” language, but because of the “traditional equity powers of a court.” Id., at 400. Emphasis on broad equity power, even in the face of a silent statute, also appears in Mitchell v. Robert DeMario Jewelry, Inc., 361 U. S. 288, 290-291 (1960); Scripps-Howard Radio, Inc. v. FCC, 316 U. S. 4 (1942); Arrow Transportation Co. v. Southern R. Co., 372 U. S. 658, 671 n. 22 (1963); see L. Jaffe, Judicial Control of Administrative Action 659 (1965), and is sometimes related to the All Writs Act, 28 U. S. C. § 1651 (a). FTC v. Dean Foods Co., 384 U. S. 597, 603-604 (1966).

The broad language of the FOIA, with its obvious emphasis on disclosure and with its exemptions carefully delineated as exceptions; the truism that Congress knows how to deprive a court of broad equitable power when it chooses so to do, Scripps-Howard, supra, 316 U. S., at 17; and the fact that the Act, to a definite degree, makes the district courts the enforcement arm of the statute, 5 U. S. C. § 552 (a) (3), persuade us that the Babcock and *20Switchmen’s Union principle of a statutorily prescribed special and exclusive remedy is not applicable to FOIA cases. With the express vesting of equitable jurisdiction in the district court by § 552 (a), there is little to suggest, despite the Act’s primary purpose, that Congress sought to limit the inherent powers of an equity court.

IY

We find it unnecessary, however, to decide in these cases, whether, or under what circumstances, it would be proper for the District Court to exercise jurisdiction to enjoin agency action pending the resolution of an asserted FOIA claim. We hold only that in a renegotiation case the contractor is obliged to pursue its administrative remedy and, when it fails to do so, may not attain its ends through the route of judicial interference. The nature of the renegotiation process mandates this result, and, were it otherwise, the effect would be that renegotiation, and its aims, would be supplanted and defeated by an FOIA suit.19

Before the adoption of the FOIA this Court consistently held that the design of the Renegotiation Act was to have renegotiation proceed expeditiously without interruption for judicial review, and that the Board’s proceedings were not to be enjoined prior to the exhaustion of the administrative process. This was the result where the proceedings were challenged on constitutional grounds, Aircraft & Diesel Equipment Corp. v. Hirsch, 331 U. S. 752 (1947); Lichter v. United States, 334 U. S. 742, 789-793 (1948), on statutory grounds, Macauley v. Waterman S. S. Corp., 327 U. S. 540 (1946), and on procedural grounds, Lichter, 334 U. S., at 791. The *21Court’s emphasis was on the absence of any “lawful function” on the part of the courts “to anticipate the administrative decision with their own,” Aircraft, 331 U. S., at 767; on the availability of a due process hearing in the post-administrative de novo proceeding in the Tax Court, Macauley, 327 U. S., at 543, where constitutional as well as nonconstitutional issues could be resolved, Aircraft, 331 U. S., at 769 n. 30, citing 89 Cong. Rec. 9930 (1943),20 and at 771; and on the Act’s provisions for expeditious settlement in informal negotiation free “from the tedious burden of litigation.” Id., at 770.

In Aircraft the Court rejected arguments substantially the same as those advanced by the respondents here, id., at 758 n. 12 (inability to participate effectively because of lack of information upon which the Board had relied, see No. 95, O. T. 1946, Tr. of R., Vol. I, p. 141), and refused to permit renegotiation to be enjoined. “To countenance short-circuiting of the Tax Court proceedings here would be, under all the circumstances but more especially in view of Congress’ policy and command with respect to those proceedings, a long overreaching of equity’s strong arm.” 331 U. S., at 781.

Reflection upon the nature of the Renegotiation Board’s process fortifies these conclusions. The character and the entire atmosphere of the process is negotiation — that is, renegotiation — of an existing contract. And negotiation is a bargaining process, with give and *22take, and with stress upon and use of the strengths of one’s own position and the weaknesses of the position of the other party. It is in a process such as this where the phrase "leading from strength” has been so effectively transferred in practical application from the card table to the world of commerce. It is part of the warp and woof of production. It is pure bargaining — permitted by the statute with respect to contracts already made — the same kind of bargaining that produces the union-employer agreement or the transfer of substantial property from the willing seller to the interested buyer.

We see nothing in the adoption of the FOIA in 1966 that impinges upon the settled law of the Aircraft-Lichter-Macauley cases or that warrants an exception to the principle they espouse. Nothing new by way of due process emerged with the FOIA. Nothing therein indicates that Congress wished to change the Renegotiation Act’s purposeful design of negotiation without interruption for judicial review. FOIA’s stress was on disclosure, to be sure, but it was on disclosure for the public, EPA v. Mink, 410 U. S. 73, 80 (1973), and not for the negotiating self-interested contractor. Id,., at 86; see K. Davis, Administrative Law Treatise § 3A.4, p. 120, § 3A.29, p. 171 (Supp. 1970). And when Congress in 1971 reviewed the Renegotiation Act and substituted the Court of Claims for the Tax Court, no other significant change in the existing process was effected. See S. Rep. No. 92-245 (1971), accompanying. H. R. 8311, which became the amending statute, Pub. L. 92-41, 85 Stat. 97.

It is no answer to say, as Bannercraft and Astro urge, that Aircraft, Lichter, and Macauley relate only to issues on the merits over which Congress had vested jurisdiction in the first instance in the Board and then in the Tax Court. We read those decisions otherwise.

*23Seeking injunctive relief during the pendency of renegotiation encourages delay through resort to preliminary litigation over an FOIA claim. The delay is not imaginary or without ultimate consequence. The present cases provide an example of this, for each has been pending now for more than three years. The Government is foreclosed from taking action to recover excessive profits until the Board’s final order is entered; even then, interest does not begin to run until 30 days after the entry of that order. 50 U. S. C. App. §§ 1215 (b)(1) and (2). The contractor, by delay, has little to lose and much to gain.

There is no limitation or denial of the contractor’s normal litigation rights when the renegotiation process is at end. The contractor may institute its de novo proceeding in the Court of Claims, unfettered by any prejudice from the agency proceeding and free from any claim that the Board’s determination is supported by substantial evidence. There the usual rights of discovery are available.21 And there the parties are not bound by a prior determination made at any level of the Renegotiation Board structure. 50 U. S. C. App. § 1218. That proceeding is the judicial remedy at law provided by the Renegotiation Act and is adequate protection against injury. Note, 41 Geo. Wash. L. Rev. 1072, 1084 (1973). We note that a contractor does not become obligated to remit excessive profits until termination of the Court of Claims suit, if it elects that course. The injury suffered, absent an injunction, is no more than the risk of being *24unsuccessful in the de novo bargaining process and the incurrence of the expense incident to renegotiation.22 Mere litigation expense, even substantial and unrecoupable cost, does not constitute irreparable injury. Myers v. Bethlehem Shipbuilding Corp., 303 U. S. 41, 51-52 (1938); L. Jaffe, Judicial Control of Administrative Action 429 (1965). Without a clear showing of irreparable injury, see Virginia Petroleum Jobbers Assn. v. FPC, 104 U. S. App. D. C. 106, 111, 259 F. 2d 921, 926 (1958), failure to exhaust administrative remedies serves as a bar to judicial intervention in the agency process. Myers, supra; Sears, Roebuck & Co. v. NLRB, 153 U. S. App. D. C. 380, 382, 473 F. 2d 91, 93 (1972).

Interference with the agency proceeding opens the way to the use of the FOIA as a tool of discovery, see Sears, Roebuck & Co. v. NLRB, 433 F. 2d 210, 211 (CA6 1970), over and beyond that provided by the regulations issued by the Renegotiation Board for its proceedings. See 32 CFR §§ 1480.1-1480.12 (1972).23 Discovery for litigation purposes is not an expressly indicated purpose of the Act. Protection for the contractor in the renegotiation process is afforded through the injunctive power specifically bestowed by 5 U. S. C. § 552 (a)(3).

The Renegotiation Act and its predecessors obviously emerged from congressional awareness that, with the vastness of defense expenditure, overcharging and misappropriation of public funds by unscrupulous contractors and those fortuitously placed to perform needed work were almost inevitable. The target of the legis*25lation was excessive profit, not the fair and reasonable one. The latter was anticipated and accepted. The line between a reasonable profit and excessive profit is not always easily ascertained or brightly lit. But the ascertainment of excessive profits was a duty vested by the Congress in the Renegotiation Board in the first instance. The Board thus is the fulcrum of a process that enables the Government initially to consult a contractor, to make a contract with it, and then to have the contract subject to modification for excessive profits, whenever they materialize, without violation of the Due Process Clause of the Fifth Amendment. The disgorging of excessive profits is not by way of a tax, .but the process is not unlike the imposition of a tax equivalent to the excessive profits. Congress’ initial placing of the contractor-initiated final proceeding in the Tax Court is indicative of the relationship.

Of course, there is uncertainty in the renegotiation process. And, of course, that uncertainty is lessened or eliminated if the contractor, like the poker player, is able to ascertain all the cards in the Board’s hand. There is risk, also, when the contractor accepts the determination of excessive profits made at any level of the renegotiation process. These risks, however, are the same risks that are inherent in the negotiation and voluntary settlement of any dispute. The one who pays possibly might pay less if he resorts to the factfinder instead of making the settlement. But he might pay more. That is the calculated risk he takes. It is the calculated risk provided for by Congress in the administrative process it prescribed in the Renegotiation Act. It is not a risk ungenerously laid upon the contractor, for it is counterbalanced by the profound interest of the public in the recapture of excessive profits that may flow to the contractor under its government contracts.

*26We stress, in conclusion, that the merits are not before us. They are yet to be decided by the District Court. Whether any demand made by these contractors is so vague as not to constitute a “request for identifiable records,” 5 U. S. C. § 552 (a) (3), or is for material exempt from disclosure under 5 U. S. C. § 552 (b), are questions that remain open for decision on remand.

The judgment of the Court of Appeals is reversed, and the case is remanded for further proceedings consistent with this opinion.

It is so ordered.

with whom Mr. Justice Stewart, Mr. Justice Marshall, and Mr. Justice Powell concur, dissenting.

The Court reverses the Court of Appeals, saying that respondent-contractors had not exhausted their administrative remedies. At issue is whether data in possession of the Renegotiation Board and relevant to the controversy between respondents and that Board should be disclosed to respondents. That raises a question under the Freedom of Information Act. It is, I submit, clear that respondents had exhausted every known way to obtain those data through administrative channels. Nothing remained to be done at that level. The District Court is the enforcement arm of the FOIA. Today’s decision, however, says that court cannot act. Hence respondents are without remedy. The end result is to make the FOIA a dead letter in this area. Hence my dissent.

The nature of the so-called administrative law aspects of the problems under the Renegotiation Act is unique. The aim, of course, is the elimination of excessive profits of contractors and subcontractors in the national defense program, 50 U. S. C. App. § 1211. Detailed financial information must be filed with the Re*27negotiation Board, id., § 1215 (e)(1). If on the basis of those data the Board decides to proceed, it refers the case to a Regional Renegotiation Board which determines tentatively the amount of excessive profits, 32 CFR § 1472.3 (e).1 A conference with the contractor is then arranged. It may agree with the Regional Board's determination or contest it. If the latter, a second conference is held with a panel of the Regional Board which hears the arguments of the contractor and submits its recommendations to the Regional Board which may be for a greater or lesser amount than the original tentative determination, id., §§ 1472.3 (f), (h), (i). Thereupon the Regional Board makes its recommendation, id., § 1472.3 (i). If the contractor is still dissatisfied, it can appeal to the Renegotiation Board itself. In that event the case is assigned to a division of the Board which is not bound by or limited to any finding or determination of the Regional Board, id., § 1472.4 (b). The division studies the case de novo and makes a recommendation to the Board which then makes a determination greater than, equal to, or less than any of the prior determinations, id., § 1472.4 (d). Even then the renegotiation process continues, the Board seeking to obtain the contractor’s voluntary agreement. Only if that effort fails is a final order determining the amount of excessive profits made, ibid.

That is the end of the administrative road; but the contractor still has an appeal to the Court of Claims which may redetermine de novo what the excessive profits are, 50 U. S. C. App. § 1218 (1970 ed., Supp. II); and from the Court of Claims certiorari may be sought here, id., § 1218a (1970 ed., Supp. II).

*28The history of the Act makes plain what can be inferred from the nature of the administrative process just described — that Congress chose negotiation, not confrontation or traditional adjudication, as the desirable route. The Act requires the Board to “endeavor to make an agreement with the contractor or subcontractor with respect to the elimination of excessive profits,” id., § 1215 (a). The pressure is on the contractor to settle, as at each successive step in the procedure its liability may be increased. The standards are rather vague and imprecise, §§ 1213 (e)(1)-(6),2 the regulations stating that “[reasonable profits will be determined in every case by over-all evaluation of the particular factors present and not by the application of any fixed formula with *29respect to rate of profit, or otherwise,” 32 CFR § 1460.8. The vagueness of the standards and the risk of an increase in liability at every level of the administrative process have a powerful coercive influence. Approximately 88% of the Board’s cases are ended by voluntary agreement, coercive orders being entered in only 12% of the cases. See Fifteenth Annual Report, Renegotiation Board 13 (1970).

In the three cases involved in this litigation the District Court entered its stay orders before the contractors had run the gantlet of the administrative process in the limited sense that each of them had another opportunity to negotiate a lower settlement with the Board, not counting a de novo hearing before the Court of Claims.

The documents which the contractors want are in possession of the Board. These documents, it is said, will reveal the strength or weakness of the Board’s case against the contractors and the facts or assumptions on which the Board relies in assessing liability. Without those documents, it is said, any meaningful negotiation, envisioned by the Act, is difficult or impossible. Future de novo review is not meaningful, it is said, since the contractors are completely in the dark as to the practical considerations which could end the dispute, if the documents were made available. Disclosure of the documents aids negotiation, which is the aim of the Act, and disclosure is necessary and appropriate to carry out the purposes of the Act.

The Court properly holds that the Renegotiation Board is an “agency” within the meaning of the Freedom of Information Act, 5 U. S. C. §552 (a). The Court also properly holds that §552 (a)(3), which grants the district court jurisdiction “to enjoin the agency from withholding agency records and to order the production of any agency records improperly withheld from the complainant,” makes that court the en*30forcement arm of the FOIA. But it denies relief here on the ground that these contractors are obliged to pursue their “administrative remedy” before going to court for an enforcement order.

The Court relies on Aircraft & Diesel Equipment Corp. v. Hirsch, 331 U. S. 752, and other decisions of that vintage which established a judicial “hands off” policy in renegotiation cases until the case had reached the Tax Court (now the Court of Claims) stage. But those cases antedated the FOIA. That Act, contrary to what the Court says, had as one of its purposes “discovery for litigation purposes.” Congress was concerned not only with the press and the general public when it lifted the veil of secrecy surrounding federal agencies but also with litigants. According to the Senate Report, the new FOIA was designed in part to “prevent a citizen from losing a controversy with an agency because of some obscure and hidden order or opinion which the agency knows about but which has been unavailable to the citizen simply because he had no way in which to discover it,” S. Rep. No. 813, 89th Cong., 1st Sess., 7.

The FOIA deals with problems of discovery, to use a lawyer’s term, and it does not leave the formulation of precise rules of discovery exclusively to the agencies themselves but, as noted, makes the district court the enforcement arm of the Act.

Exhaustion of administrative remedies has skeins of various colors, McKart v. United States, 395 U. S. 185, 193-194. Ordinarily courts do not interfere until the agency has completed its action, id., at 194, “or else has clearly exceeded its jurisdiction,” ibid. The present case does not entail supplanting administrative expertise on the merits. The issues tendered concern only administrative procedure.

The court errs in saying that the contractors did not exhaust their administrative'remedies. They strenuously *31sought the information mandated by the FOIA and exhausted all administrative procedure for obtaining it. That right to full disclosure, if not granted now, is forever lost. For as these contractors seek relief at a higher tier of the administrative process, the reviewing body will not consider whether the contractors could have negotiated settlements of a lesser amount if they had had access to the documents whose discovery is involved here. As Judge J. Skelly Wright said below:

“[I]t should be apparent here that if the contractors are to be granted relief at all they must have it now before the administrative momentum carries their cases beyond the point where the harm can be undone. If we take Congress’ declaration of purpose seriously, then the parties are supposed to negotiate over excess profits at the lower administrative levels. The seemingly endless de novo reviews were intended to make the negotiating process work, not to provide a substitute for negotiation. If the negotiating process fails to occur, the opportunity is lost forever. To say that compulsory awards imposed by the Board or the Court of Claims at the end of the process provide an adequate remedy is to ignore the difference between an agreement freely arrived at, as preferred by Congress, and a judgment imposed by a court of law.” 151 U. S. App. D. C. 174, 186, 466 F. 2d 345, 357.

The proceeding in the Court of Claims proscribes review of the Board. Title 50 U. S. C. App. § 1218 (1970 ed., Supp. II) states:

“A proceeding before the Court of Claims to finally determine the amount, if any, of excessive profits shall not be treated as a proceeding to review the determination of the Board, but shall be *32treated as a proceeding de novo.” (Emphasis added.)

There is no power, as I see it, for the Court of Claims to remand the case to the Board to cure any irregularity in its procedures. If these contractors are to have the remedy of full disclosure, it is now or never.

A procedure that accelerates settlements furthers the policy of the Renegotiation Act. The Board judges the profits of the contractors involved in the present case with the profits of other contractors in determining whether their profits are excessive. The relative prices, costs, and profits of those other companies are germane to the ultimate issue to be resolved. One oi these contractors has a low “front office” overhead, as the executive officer is the president who has only a secretary. The rest of the employees are engaged in production. The contractor who has a low “front office” expense is penalized for efficiency, if its profits are reduced to the scale allowed contractors who have a high “front office” expense. The Board in its Regulations under the FOIA makes “available for public inspection and copying summaries of facts and reasons issued by the Board,” 32 CFR § 1480.5 (a). But an agency making decisions has no right to make secret the basis of those decisions,3 if the FOIA is to have any real meaning in the *33activities of the Renegotiation Board. If a contractor does not know the reasons why the Board or any of its agencies cuts the profits of a contractor 95%, it has no meaningful criteria to determine whether it should settle with the Board or continue to pursue its remedies up the escalator of the hierarchy. It is as if a court could rule for the plaintiff or for the defendant without ever having to disclose its reasons.

The result of today’s decision is to put the citizen, in a game of “blind man’s buff” with the Renegotiation Board. Enforcement of the policy of full disclosure under the FOIA is no intrusion in the determination of the merits of the controversy before the Board. The expertise of the Board does not relate to the FOIA but only to the Renegotiation Act. The FOIA merely describes some of the procedure to be followed by the Board. Aircraft concerned the intrusion of the judiciary into the administrative process by a suit to declare the whole renegotiating procedure unconstitutional prior to any adjudication of the merits of the contractor’s claim. Granting the relief asked in that case would have gutted the statutes. Granting the relief here would merely make the rules of discovery, established by Congress, applicable to the Renegotiation Board. Denial of the relief establishes a regime of secrecy when Congress has demanded disclosure and gives the Renegotiation Board a degree of administrative absolution4 at war with the philosophy of the FOIA.

*34The trend at the federal level has been the evolution of administrative agencies as principalities of power. The Administrative Procedure Act, 60 Stat. 237, was passed as an antidote to that development. It contained a provision in § 3, 5 U. S. C. § 1002 (1964 ed.), for disclosure of information by the agencies. But it was soon criticized because it was “full of loopholes which allow agencies to deny legitimate information to the public. It has been shown innumerable times that information is often withheld only to cover up embarrassing mistakes or irregularities and justified by such phrases . . . as — 'requiring secrecy in the public interest,’ 'required for good cause to be held confidential,’ and 'properly and directly concerned.’ ” S. Rep. No. 1219, 88th Cong., 2d Sess., 8. As the House Report stated in support of supplanting § 3 of the Administrative Procedure Act with the FOIA “Government agencies whose mistakes cannot bear public scrutiny have found good cause’ for secrecy.” 5 H. R. Rep. No. 1497, 89th Cong., 2d Sess., 6. As respects the role of the courts the House Report stated:

“The proceedings are to be de novo so that the court can consider the propriety of the withholding instead of being restricted to judicial sanctioning of agency discretion. The Court will have authority whenever it considers such action equitable and appropriate to enjoin the agency from withholding its records and to order the production of agency records improperly withheld. The burden of proof is placed upon the agency which is the only party able to justify the withholding. A private citizen *35cannot be asked to prove that an agency has withheld information improperly because he will not know the reasons for the agency action.” Id., at 9.

The reluctance of the Court to require this administrative agency to live under the law calls to mind the admonition of Mr. Justice Stone speaking for the Court in United States v. Morgan, 307 U. S. 183, 191:

“Court and agency are the means adopted to attain the prescribed end, and so far as their duties are defined by the words of the statute, those words should be construed so as to attain that end through coordinated action. Neither body should repeat in this day the mistake made by the courts of law when equity was struggling for recognition as an ameliorating system of justice; neither can rightly be regarded by the other as an alien intruder, to be tolerated if must be, but never to be encouraged or aided by the other in the attainment of the common aim.”

I would affirm the judgment below.
