Since their promulgation, the Secretary of the Interior has consistently construed Executive Order No. 8979 and Public Land Order No. 487, relating to the disposition of public lands located in the Kenai National Moose Range in Alaska, not to bar the issuance of oil and gas leases. His interpretation has been made a repeated matter of public record, and a number of leases have been developed, at great expense, in reliance on it. If, therefore, his interpretation of the orders is not unreasonable, courts must respect it. Pp. 4-18.

MR. CHIEF JUSTICE WARREN delivered the opinion of the Court.
At issue in this case is the effect of Executive Order No. 8979 and Public Land Order No. 487 upon the Secretary of the Interior's authority to issue oil and gas leases.
Between October 15, 1954, and January 28, 1955, D. J. Griffin and other persons - hereinafter collectively referred to as the Griffin lessees - filed applications for oil and gas leases on approximately 25,000 acres located in the Kenai National Moose Range in Alaska. On August 14, 1958, the respondents filed offers to lease the same lands. Section 17 of the Mineral Leasing Act of 1920 provides, in relevant part, that "the person first making application for the lease who is qualified to hold a lease . . . shall be entitled to a lease of such lands without competitive bidding. . . ." 41 Stat. 443 (1920), as amended by 60 Stat. 951 (1946), 30 U.S.C. 226 (1958 ed.). The Bureau of Land Management of the Department of the Interior determined that the Griffin lessees were the persons who had applied first, and issued to them leases on the tracts, effective September 1, 1958. Respondents' applications were reached for processing in [380 U.S. 1, 3] October 1959, and were rejected on the ground that the lands had been leased to prior applicants. 1
From the rejection of their applications, respondents appealed to the Director of the Bureau of Land Management and then to the Secretary of the Interior, both of whom affirmed the decision. 68 I. D. 256 (1961). Respondents then brought an action in the nature of mandamus, in the United States District Court for the District of Columbia, to compel the Secretary to issue oil and gas leases to them. The District Court granted summary judgment in favor of the Secretary dismissing the complaint. The Court of Appeals for the District of Columbia Circuit reversed, holding that Executive Order No. 8979, the order creating the Moose Range in 1941, and Public Land Order No. 487, issued by the Secretary in 1948, 2 had withdrawn the lands in controversy from availability for leasing under the Mineral Leasing Act, and that the lands remained closed to leasing until they were reopened by a revised departmental regulation on August 14, 1958. The court therefore held that the Griffin applications, filed while the land was closed, were ineffective, rendering the leases issued on them nullities; the respondents, as the persons first making application [380 U.S. 1, 4] after the promulgation of the 1958 regulation, were held to be entitled to the leases. 116 U.S. App. D.C. 379, 324 F.2d 411 (1963). We granted certiorari, 376 U.S. 961 .
We conclude that the District Court correctly refused to issue a writ of mandamus, and accordingly reverse the decision of the Court of Appeals. Since their promulgation, the Secretary has consistently construed both orders not to bar oil and gas leases; moreover, this interpretation has been made a repeated matter of public record. While the Griffin leases and others located in the Moose Range have been developed in reliance upon the Secretary's interpretation, respondents do not claim to have relied to their detriment upon a contrary construction. The Secretary's interpretation may not be the only one permitted by the language of the orders, but it is quite clearly a reasonable interpretation; courts must therefore respect it. McLaren v. Fleischer, 256 U.S. 477, 481 ; Bowles v. Seminole Rock Co., 325 U.S. 410, 413 -414.
The Mineral Leasing Act of 1920, 41 Stat. 437, 30 U.S.C. 181 et seq. (1958 ed.), gave the Secretary of the Interior broad power to issue oil and gas leases on public lands not within any known geological structure of a producing oil and gas field. Although the Act directed that if a lease was issued on such a tract, it had to be issued to the first qualified applicant, it left the Secretary discretion to refuse to issue any lease at all on a given tract. United States ex rel. McLennan v. Wilbur, 283 U.S. 414 . The Act excluded from its application certain designated lands, 3 but did not exclude lands within wildlife refuge areas. [380 U.S. 1, 5]
The Kenai National Moose Range was created in 1941 by Executive Order No. 8979, 6 Fed. Reg. 6471, by which approximately two million acres of the public domain were set aside "as a refuge and breeding ground for moose." The order provided that "[n]one of the above-described lands excepting [a defined area] shall be subject to settlement, location, sale, or entry, or other disposition (except for fish trap sites) under any of the public-land laws applicable to Alaska . . . ." On November 8, 1947, the Secretary promulgated the first general regulation dealing with the issuance of oil and gas leases within wildlife refuges. It provided simply that such leases had to be subjected to an approved unit plan and contain a provision prohibiting drilling or prospecting without the advance consent of the Secretary. 12 Fed. Reg. 7334.
On June 16, 1948, the Secretary issued Public Land Order No. 487, 13 Fed. Reg. 3462:
By an intra-agency memorandum dated August 31, 1953, the Director of the Bureau of Land Management advised the Regional Administrators of the Bureau and managers of the local land offices that "a possible revision of policy and regulations" on leasing in wildlife refuges was being studied, and directed them that "[p]ending the completion of this study and the possible revision of existing regulations, you will suspend action on all pending oil and gas lease offers and applications for lands within such refuges." It is not disputed, and subsequent memoranda make clear, that the 1953 memorandum did not purport to prevent either the issuance of leases with [380 U.S. 1, 7] the approval of the national office or the continued filing of lease offers. 5 During late 1954 and early 1955, a number of individuals filed applications for oil and gas leases in the northern half of the Moose Range; among these applications were those of the Griffin lessees. Action on them was suspended in accordance with the 1953 directive, but none was rejected on the ground that the land in question was closed to leasing. 6
On September 9, 1955, the Secretary issued Public Land Order No. 1212, 20 Fed. Reg. 6795, revoking in its entirety Public Land Order No. 487. After granting certain preferences, it provided:
On December 8, 1955, the anticipated revision of the 1947 refuge-leasing regulation was promulgated. 20 Fed. Reg. 9009. It was more restrictive than the old regulation, and gave increased power to the Fish and Wildlife Service to approve or disapprove oil and gas development of refuges. It listed in an Appendix A a number of refuges (not including Kenai) in which, because of their importance to the preservation of rare species of plant and animal life, no leasing at all would be permitted. In Appendix B it listed certain areas (including a small part of the Moose Range not involved here) "with respect to which the Fish and Wildlife Service reports that oil and gas development might seriously impair or destroy the usefulness of the lands for wildlife conservation purposes . . . ." In such Appendix B areas, leasing was to be permitted only upon the approval by the Director of the Fish and Wildlife Service of "a complete and detailed operating program for the area." In all other wildlife areas the regulation provided that "[o]il and gas leases may be issued" provided they contain specified conditions requiring approval by the Fish and Wildlife Service of the type of prospecting to be conducted, and adoption by the [380 U.S. 1, 9] lessee of a unit plan approved by the Service. Respondents argue that even if it be assumed that (as is clearly the case) the 1955 regulation treated the lands in controversy as open to leasing, the regulation is not probative of the availability of the lands for leasing prior to 1955, and is therefore no evidence that the Secretary viewed the lands as open to leasing at the time the Griffin applications were filed. We think, however, that if the Secretary had been of the opinion that he was changing the status of that part of the Moose Range not covered by Appendix B, rather than merely imposing additional restrictions on leasing therein, he would have done so in terms more express than those used in the 1955 regulation. He did not refer to the Range as a whole; the only reference by name was to those parts of the Range which were specified in order to except them from the general provision that "[o]il and gas leases may be issued" in wildlife refuges. Though this specification supports the inference that the regulation was drafted on the assumption that the remainder of the Range was open to leasing, such indirect implication - however clearly it confirms the preexisting availability of the Range - would have been a technique inappropriate for effecting a change of the Range's status. Moreover, the President's 1952 delegation to the Secretary of power to make or modify withdrawals had directed that "[a]ll orders issued by the Secretary of the Interior under the authority of this order shall be designated as public land orders and shall be submitted . . . for filing and for publication in the FEDERAL REGISTER." Executive Order No. 10355, 17 Fed. Reg. 4831 (emphasis added). It may be that a document not labeled a public land order could in legal effect constitute an exercise of that power; however, if the Secretary had meant to exercise such power, it is likely that he would [380 U.S. 1, 10] have done so in the manner directed by the President's delegation. 7
When bills were introduced in Congress early in 1956 to restrict oil and gas leasing in wildlife refuges, the House Committee on Merchant Marine and Fisheries and the Subcommittee on Merchant Marine and Fisheries of the Senate Committee on Interstate and Foreign Commerce held extensive hearings thereon. The bills as introduced only forbade the Secretary to "dispose of" lands in wildlife refuges, and the question arose during the hearings whether that language would apply to the issuance of oil and gas leases. A representative of the Department asserted, without contradiction, that the granting of an oil and gas lease was not a "disposition" and would not be affected by the language as proposed. Hearings before the House Committee on Merchant Marine and Fisheries on H. R. 5306, etc., 84th Cong., 2d Sess., p. 98. An amendment was accordingly proposed specifically restricting oil and gas leasing. Neither committee reported [380 U.S. 1, 11] favorably on the bills. However, the House Committee submitted a report stating that it had been decided to try, for an experimental period of time, an arrangement whereby each proposed alienation or relinquishment of any interest the Fish and Wildlife Service had in lands under its jurisdiction would be submitted to the Committee, which would within 60 days approve or disapprove the action contemplated. H. R. Rep. No. 1941, 84th Cong., 2d Sess., pp. 12-13. This resolution of the issue suggests that the Committee accepted the Department's view that the Secretary had pre-existing authority to grant oil and gas leases in the Moose Range, and was concerned only with the way in which he exercised his discretion.
Pursuant to the agreement, the House Committee on Merchant Marine and Fisheries held public hearings on July 20 and 25, 1956, on a proposal from the Fish and Wildlife Service for the issuance of 30 oil and gas leases on 71,680 acres in the northern half of the Moose Range - located within the area encompassed by Executive Order No. 8979 - for which lease applications had been filed in 1954 by amicus curiae Richfield Oil Corporation and others. The proposal contemplated that the leases would be subject to the Swanson River Unit plan of operation, which had been approved by the Bureau of Land Management, the Geological Survey and the Fish and Wildlife Service, all branches of the Department of the Interior. At the hearing on the proposal a spokesman for the National Wildlife Federation urged that Executive Order No. 8979 precluded the issuance of the leases. Transcript of Hearing before the House Committee on Merchant Marine and Fisheries, July 20 and 25, 1956, Lease of Portions of Kenai National Moose Range, pp. 17, 19, 24-26. But see id., pp. 35-36; letter, July 24, 1956, Deputy Solicitor, Department of the Interior, to Hon. E. L. [380 U.S. 1, 12] Bartlett, Delegate to Congress from Alaska, following id., p. 30. On July 25, 1956, however, the Committee's Chairman advised the Director of the Fish and Wildlife Service that the Committee unanimously had concluded that issuance of the leases would not be detrimental to the wildlife values of the Moose Range, and had concurred in the proposal to issue the leases. 8
Following the Committee's approval the leases were issued, an exploratory well was drilled and oil was discovered in commercial quantities in July 1957. See Rep. Alaska Gov. 88 (1957); Rep. Secy. Int. 356 (1957); Rep. Secy. Int. 104, 199, 258, 356 (1958). The Swanson River leases soon became again a subject of congressional concern, when the Secretary of the Interior - realizing that although he had authority to issue leases on dry land, he lacked such authority with respect to lands beneath Alaskan inland navigable waters - asked Congress for authority to issue leases on Alaskan water bottoms, and to add to the leases already issued in Alaska and to applications pending there the water bottoms within their [380 U.S. 1, 13] boundaries. 9 The Senate Committee reported favorably on the proposed bill, saying:
Meanwhile, the controversy over the leasing policies to be followed in wildlife refuges was resolved by the adoption, on January 8, 1958, of another complete revision of the regulation. 23 Fed. Reg. 227, 43 CFR 192.9. The revision represented a near-total victory for the conservationists. It altogether prohibited oil and gas leasing, unless necessary to prevent draining, in [380 U.S. 1, 14] wildlife refuges - with two exceptions: lands withdrawn for a dual purpose, and wildlife refuges located in Alaska. As to lands falling within these two excepted categories, the Bureau of Land Management and the Fish and Wildlife Service were to reach agreements specifying the lands which "shall not be subject to oil and gas leasing" and to decide on provisions to be required in leases issued on the remaining lands. The agreements were to become effective upon approval by the Secretary and publication in the Federal Register. The regulation further provided that "[a]ll pending offers or applications heretofore filed for oil and gas leases covering game ranges, coordination lands, and Alaska wildlife areas, will continue to be suspended until the agreements referred to . . . shall have been completed," and that no new lease applications would "be accepted for filing until the tenth day after the agreements . . . are noted on the land office records."
Pursuant to the regulation, there was published in the Federal Register on August 2, 1958, an order of the Secretary announcing the agreement reached with respect to the Moose Range. 23 Fed. Reg. 5883. The order decreed that certain lands within the Range (essentially the southern half) "are hereby closed to oil and gas leasing because such activities would be incompatible with management thereof for wildlife purposes." It then provided:
Soon after the issuance of the regulation and the implementing order, the pending applications were acted upon; within the next two months, 294 leases covering 621,234 acres were issued in the area subject to Executive Order No. 8979, in response to applications (including those of the Griffin lessees) filed in 1954 and 1955. When these figures are added to those covering leases issued prior to 1958 (primarily those in the Swanson River area), it appears that in the area subject to Executive Order No. 8979, the Secretary issued a total of 331 leases covering 696,680 acres on applications filed during the period the Court of Appeals held that the area was closed to leasing. Thus, prior to the commencement of the instant suit, the Secretary had leased substantially the entire area [380 U.S. 1, 16] in controversy; 11 the Solicitor General further assures us that the lessees and their assignees had, in turn, expended tens of millions of dollars in the development of the leases.
When faced with a problem of statutory construction, this Court shows great deference to the interpretation given the statute by the officers or agency charged with its administration. "To sustain the Commission's application of this statutory term, we need not find that its construction is the only reasonable one, or even that it is the result we would have reached had the question arisen in the first instance in judicial proceedings." Unemployment Comm'n v. Aragon, 329 U.S. 143, 153 . See also, e. g., Gray v. Powell, 314 U.S. 402 ; Universal Battery Co. v. United States, 281 U.S. 580, 583 . "Particularly is this respect due when the administrative practice at stake `involves a contemporaneous construction of a statute by the men charged with the responsibility of setting its machinery in motion, of making the parts work efficiently and smoothly while they are yet untried and new.'" Power Reactor Co. v. Electricians, 367 U.S. 396, 408 . When the construction of an administrative regulation rather than a statute is in issue, deference is even more clearly in order.
Moreover, as the discussion in Section I of this opinion demonstrates, the Secretary has consistently construed Executive Order No. 8979 and Public Land Order No. 487 not to bar oil and gas leases.
Executive Order No. 8979, 6 Fed. Reg. 6471, provided:
Respondents' reliance upon Wilbur v. United States ex rel. Barton, 60 App. D.C. 11, 46 F.2d 217 (1930), aff'd sub nom. United States ex rel. McLennan v. Wilbur, 283 U.S. 414 , is misplaced. Involved in Wilbur was the meaning of language contained in the Pickett Act, 36 Stat. 847 (1910), 43 U.S.C. 141 (1958 ed.).
The Mineral Leasing Act of 1920 changed the procedure for acquiring oil and gas rights in public lands: the Secretary was empowered to issue prospecting permits and required, in the event a discovery was made under the permit, to issue a lease which entitled the lessee to extract the mineral, but gave him no right in the land itself. 17 From 1920 on, therefore, the language of the Pickett Act no longer technically encompassed leasing. Nonetheless, it was clear that the Act had been specifically designed to legitimize orders like the 1909 withdrawal order. The Court of Appeals reasonably concluded in Wilbur that the fact that Congress had in 1920 changed the procedure - from "location" to "leasing" - for acquisition of oil and gas rights afforded no reason for concluding that they had thereby intended to cut back the power granted in 1910. 60 App. D.C., at 14-15, 46 F.2d, at 220-221. Thus neither that holding by the Court of Appeals nor this Court's affirmance in any way casts doubt upon the reasonableness of the Secretary's interpretation of the orders at bar, which were drafted long after the Mineral Leasing [380 U.S. 1, 23] Act had done away with location as a means of acquiring oil and gas rights.
The placement of the fish trap exception - "(except for fish trap sites)" - a phrase admittedly not relating to alienation of title to land, does tend to cut against the Secretary's interpretation of Executive Order No. 8979. However, it appears that the exception was designed to assure the Alaskans, whose livelihood is largely dependent on the salmon catch, that they could continue - despite the order - to use fish traps. Cf. Organized Village of Kake v. Egan, 369 U.S. 60 . Since it was a reassurance not technically necessary and therefore not functionally related to any part of the regulation, it is no surprise to find it carelessly placed. Compare Executive Order No. 8857, 6 Fed. Reg. 4287, establishing the Kodiak National Wildlife Refuge. We do not think the position of the fish trap exception is sufficient to justify a court's overturning the Secretary's construction as unreasonable.
Public Land Order No. 487 withdrew the lands it covered from "settlement, location, sale or entry," but contained no reference to "other disposition." Nor did it contain anything analogous to the fish trap exception. The reasonableness of the Secretary's interpretation of Public Land Order No. 487 therefore follows a fortiori from the reasonableness of his construction of Executive Order No. 8979.
[ Footnote 2 ] Public Land Order No. 487 encompassed the land for which respondent Coyle applied; the land for which the other nine respondents filed is covered by Executive Order No. 8979.
[ Footnote 3 ] Section 1 of the Act excludes "lands acquired under the Act known as the Appalachian Forest Act, approved March 1, 1911 (36 [380 U.S. 1, 5] Stat. 961), and those in incorporated cities, towns, and villages and in national parks and monuments, those acquired under other Acts subsequent to February 25, 1920, and lands within the naval petroleum and oil-shale reserves, except as hereinafter provided . . .," 41 Stat. 437-438 (1920), as amended, 60 Stat. 950 (1946), 30 U.S.C. 181 (1958 ed.).
[ Footnote 4 ] See Public Land Order No. 751 of August 29, 1951, 16 Fed. Reg. 9044, which withdrew 160 acres for the Civil Aeronautics Administration, and 88.86 acres for townsite purposes, and Public Land Order No. 778 of December 29, 1951, 17 Fed. Reg. 159, which withdrew a number of tracts, aggregating 4,280 acres, for the use of the Army.
[ Footnote 5 ] See memorandum, February 15, 1954, Director, Bureau of Land Management, to Assistant Secretary of the Interior; memorandum, August 12, 1955, Director, Bureau of Land Management, to Area Administrator, Area 4 (Alaska); 102 Cong. Rec. A6582.
[ Footnote 6 ] In his report for the fiscal year ending June 30, 1955, the Governor of Alaska stated: "Residents of Alaska and major oil companies have continued to file lease applications and send exploratory parties into various parts of the Territory. The Kenai Moose Reserve on the Kenai Peninsula is covered with 325 lease applications awaiting decision of the Secretary of the Interior as to what stipulations for the protection of wildlife should be inserted in leases, if they are issued." Rep. Alaska Gov. 60-61 (1955); see also Rep. Secy. Int. 65 (1953).
[ Footnote 7 ] It appears that the Bureau regarded the amended regulations as automatically vacating the 1953 suspension order; however, upon the almost immediate introduction in Congress of bills further to restrict leasing in wildlife refuges, the field offices were directed once again to withhold final action on lease applications. See Richard K. Todd et al., 68 I. D. 291, 298 (1961). In further support of the claim that the 1955 regulation is worthless as an indication of the pre-existing status of the lands covered thereby, respondents urge that Appendix B listed "wildlife refuges which were closed by the terms of the orders creating them." However, of the 176 refuges listed in Appendix B, respondents point to only one: the Salt Plains in Oklahoma. Moreover, only a small part of the Salt Plains (543 acres out of over 30,000) was specifically withdrawn from appropriation under the mining and mineral-leasing laws Public Land Order No. 144, 8 Fed. Reg. 9430. It is therefore doubtful that a simple listing in Appendix B of the "Salt Plains," large parts of which were admittedly open to leasing prior to 1955, was intended to open the small area closed by Public Land Order No. 144.
[ Footnote 8 ] Respondents seek to capitalize on the fact that although the Swanson River Unit was not located in any of the areas designated in Appendix B of the 1955 regulation, the applicants submitted, and obtained Service approval of, a detailed operating program for the unit. There are at least two possible explanations for the submission of the plan. First, the Fish and Wildlife Service could at any time designate areas not listed in Appendix B in which leasing "might seriously impair or destroy" conservation purposes and accordingly require advance approval of operating programs for them. Submission of a plan as to the Swanson River Unit might have been regarded as a means of insuring that the Service would not so designate the area. Second, the Secretary had directed his subordinates to withhold final action on lease applications pending a further revision of the regulations. The applicants may have submitted the plan in order to persuade the Department and the House Committee that the proposed leasing was consistent not only with existing regulations but also with any that were likely to be adopted.
[ Footnote 9 ] In the hearings before the Senate Committee on Interior and Insular Affairs on the proposed bill, Mr. Gordon Goodwin, attorney for amicus curiae Richfield Oil Corporation, testified: "Well, we have pending, and have had for 2 or 3 or more years, applications for leases in the Kenai moose range, and a few leases were issued in there, and that is where the discovery was made. But, shortly after that time, the Secretary suspended all leasing in the moose range . . . and he has never lifted it yet . . . . So we have not been able to do much business up there except to a very limited extent." Hearings before the Senate Committee on Interior and Insular Affairs on H. R. 8054, 85th Cong., 2d Sess., p. 77.
[ Footnote 10 ] In announcing the order, the Secretary warned that there would be little land available to new applicants: "Most of these lands are now covered by applications that will be adjudicated under the regulations of the Department." Department of the Interior Press Release, July 25, 1958. Respondents point to the fact that in a Press Release dated January 29, 1958, announcing the forthcoming (August) order, the Secretary had indicated that he was "opening" a part of the Moose Range to leasing. The choice of this term is wholly understandable in view of the facts that general instructions to local offices not to take final action on lease applications had been outstanding since 1953, and that the regulations of January 8, 1958, had provided that no new applications would be accepted for filing until a subsequent order was issued specifying the lands which would not be subject to leasing. Therefore, the order of August 2, 1958, did, in these two senses, "open" the Range to leasing.
[ Footnote 11 ] In the area excepted from Executive Order No. 8979 but encompassed by Public Land Order No. 487, the total number of leases issued on applications filed before the revocation of the latter order was 74 covering 116,878 acres.
[ Footnote 13 ] The failure of the court below to attach proper significance to the administrative practice seems to be attributable to the fact that it was misinformed concerning that practice. The respondents' brief in the Court of Appeals stated that "[n]o leases issued for any lands within the Kenai Range between 1941 and 1958" (p. 30), and that "[t]he discovery as well as the increased activity were in areas of the Peninsula outside of the Kenai National Moose Range" (p. 40).
[ Footnote 14 ] This view is taken in Hoffman, Oil and Gas Leasing on the Public Domain, p. 33 (1951).
[ Footnote 15 ] Reference to the language of other withdrawal orders is not very fruitful. Amici curiae list 173 Executive and Public Land Orders issued between 1940 and 1952 which contained language expressly barring mineral leasing. Brief for Marathon Oil Co. and Union Oil Co. of California as amici curiae, pp. 6A-7A. However, respondents list 146 orders issued between 1936 and 1959 expressly permitting mineral leasing. Brief for Respondents, pp. 7a-10a.
[ Footnote 16 ] The Court of Appeals sought to explain the reference to the 1926 and 1927 Acts by construing the phrase "any of the public-land laws applicable to Alaska" to mean laws applicable both throughout the country and in Alaska, and opined that the 1926 and 1927 Acts were specifically added because they had application only in Alaska. However, the Secretary's interpretation of "any of the public-land laws applicable to Alaska" (as including, inter alia, laws relating to public lands located only in Alaska) is at least as natural as the Court of Appeals' interpretation (limiting the phrase to laws applicable throughout the country) and is beyond cavil a "reasonable" interpretation, which is the test the Court of Appeals should have been applying. Moreover, the Court of Appeals' conclusion that "disposition" was meant to include leasing renders the words "or to classification and lease," initiating the reference to the Acts of 1926 and 1927, superfluous.
[ Footnote 17 ] In 1935, the prospecting permit procedure was eliminated and the present direct leasing procedure substituted. Act of August 21, 1935, 49 Stat. 676-677, 30 U.S.C. 223, 226 (1958 ed.). [380 U.S. 1, 24]
