delivered the opinion of the Court.
..This is an appeal under section 250 of the Judicial dode, par. 6, from a judgment of the Supreme Court of the District of Columbia, affirmed by the Court of Appeals, granting a mandamus compelling the Secretary of the Interior to consider and allow a claim for net loéses. suffered by Logan Rives, the relator, in producing and preparing to produce manganese at the instance of the Government for war purposes, under section 5 of the Dent Act (March 2, 1919, ch. 94, 40 Stat. 1272).
Relator’s petition shows that he incurred losses aggregating $55,204.15, but that the Secretary awarded him only $23,047.36, refusing to allow him, among other items, $9,600 which he had to expend in obtaining a release from a contract to buy land containing manganese, after the, land had lost most of its value because of the armistice. The mandamus asked is to compel consideration and allowance of the claim for this particular item.
The Secretary’s answer avers that the relator received and accepted the.. $23,047.36 awarded March, 1920, but *177 refused to waive any right to further award under any subsequent legislation which might provide for further payment. The answer further denies that the Secretary refused to consider the claim, but avers that, he did so fully and rejected it. The relator demurred to the answer and on that demurrer judgment followed and the writ issued.
Mandamus issues to compel an officer to perform a purely ministerial duty. It can not be used to compel or control a duty in the discharge of which by law he is given discretion. The duty may be discretionary within limits. He.can not transgress those limits, and if he does so, he may be controlled by injunction or mandamus to keep within .them. The power of the court to intervene, if at all, thus depends upon what statutory discretion he has. Under some statutes, the discretion extends to a final construction by the officer of the statute he is executing. No court in such a case can control by mandamus his interpretation, even if it may think it erroneous. The cases range, therefore, from such wide discretion as •that just described to cases where the duty is purely ministerial, where the officer can do only one thing, which on refusal he may be compelled to do. They begin on one side with
Kendall
v.
United States,
The Dent Act was passed by Congress jn an effort to do justice.and equity to the many persons who could not obtain from the Government compensation for supplies or services furnished or losses incurred in helping the Government during the war, because of a lack of enforceable contracts or equities. As to supplies and services furnished, there was to be a settlement made by the Secretary of War,- and if this did not satisfy the claimant, he was given a right under section 2 to sue in the Court of Claims tó recover greater compensation. Section 3 gave the Secretary powqr to settle fairly and equitably claims of foreign governments and'their nationals for supplies .and' services rendered to' the American Expeditionary forces whether by contract entered into in áccordance with applicable statutory provisions or not. - By section 4, the Secretary was given power to protect sub-cpntractors in his awards.
By section 5, provision was made, not to pay for supplies Qr services rendered directly to the Government, but to relieve a class pf persons who were invited by the Gov- *179 emment to invest money in the production and preparing for the production of certain metals or materials difficult to obtain, and needed for the war, and who had thereupon incurred expense therein and had suffered losses because of the coming of the armistice and the consequent destruction 4f the market for such metals.
The said Secretary was to make adjustments and payments in each case as he should determine to be just and equitable; and the decision of the Secretary was. to be “ conclusive and final.” There were five provisos: The first imposed a limit of total expenditure under the Act. The second limited claims to those filed , within three months after the passage of the Act.
The third proviso declared: “That no claim shall be allowed or paid by said Secretary unless it shall appear to the satisfaction of the said Secretary that the expenditures so made or obligations so incurred’by the claimant were made in good faith for or upon property which contained . . . manganese . . ..in sufficient quantities to be of commercial importance.” The fourth proviso was: “ That no claims shall be paid unless it shall appear to the satisfaction of said Secretary that moneys were invested or obligations were incurred subsequent to April 6, 1917, and prior to November 12, 1918 in a legitimate attempt . to'. produce . . . manganese . . ,. for the prosecution of the war, and that no profits of any kind shall be included in the allowance of any of said claims, and that no investment for merely speculative purposes shall be recognized in any manner by said Secretary.” The 'fifth proviso declared that the settlement of any claim under the section' should not bar the Government through, any authorized^'agency or any Congressional committee thereafter duly appointed from the review .of such settlement, nor thie right to recover any money, paid by the Government to any party under the section if the Government had been defrauded.
*180 The last paragraph of the section declared “That nothing in this section shall be construed to confer jurisdiction upon any court to entertain a suit against the United States” and closed with a'proviso that in’determining the net losses of any claimant, the Secretary should take into consideration and charge to', him .the then market value of any ores or minerals on hand belonging to him, and the salvage or usable value of his machinery or other appliances claimed to' have been purchased to comply with the request of the Government.
On November 23, 1921, after the first .award in this case, section 5 was amended (Ch. 137, 42 Stat. 322) by adding another proviso, that all claimants who in response to the request of any government agency mentioned in the Act expended money “ in producing or preparing to" produce” manganese,, and had mailed their claims in time, “ if the proof in support of said claims clearly shows them to be based upon action taken in response to such request . ' . . shall be reimbursed such net losses as they may have incurred and are in justice and equity .entitled to from the appropriation in said Act. If in claims passed >upon under said Act awards have been denied or made on rulings contrary tó the provisions of this amendment, or through miscalculation, the Secretary of the Interior may award proper amounts or additional amounts.”
This amendment was brought about on the recommendation of the Secretary of the Interior, because he had felt obliged, under section' 5 as it was, to reject some 60Ü claims for failure within the time limit to> show a direct personal request or demand upon the claimant by the government authorities named in the Act and a response thereto by the claimant and because the Comptroller had.refused to pay any changed award of the ‘Secretary made after a.rehearing or to correct fniscalcu-lation.
*181 It is urged that the refusal of the Secretary to allow the loss of $9,600 on the real estate contract is in the teeth of the third proviso, which requires him to allow for expenditures made or obligations incurred “ for and' upon property ” containing manganese in sufficient quantities to be of commercial importance. The Interior Department had held from the beginning that this proviso did not embrace 'money spent for real estate or mining rights. The ruling was .based in part at least on the legislative history of the bill, which showed that it originally contained an express provision for expenditures for real estate as a proper element in calculating the net losses to be reimbursed, and that this provision was objected to as involving too speculative a subject matter and it was stricken out. The Department’s view was that expenditures “ for and upon ” property containing manganese and other metals did not include cost of real estate or mining rights because too speculative under the limitations of the fourth proviso and were intended to.be confined to expenditures for construction, equipment and machinery in development of such property.
We are asked to reject this interpretation as wholly at variance with the natural ‘and necessary meaning of the words and to confirm the courts below in enforcing a view more liberal to the claimant.
The above summary of section 5 clearly shows that Congress was seeking to save the beneficiaries from losses which it would have been under no legal obligation to make good if a private person. It was a gratuity based on equitable and moral considerations.
United
States v.
Realty Company,
Congress was occupying toward the proposed beneficiaries of. section 5 the attitude rather of a benefactor, than óf a debtor at law. Congress intended the Secretary to act for it, .and to construe the meaning of the words used to describe the elements of the net losses to be ascertained and to give effect to -his interpretation without the intervention of the courts.. This statute presents a case of as wide discretion as was held to have been vested in the Secretary of the Navy in the Decatur Case.
. Nor does, the amendment of 1921 change the effect of the Act in this regard.' His counsel 'insist that it was adopted in order to relieve claimants from previous narrow rulings of the • Secretary. There is nothing in the amendment that indicates the Congressional 'purpose to do more than it purports to do,- i. e., to enable the Secretary .to entertain claims for losses incurred at the instance of any government agencies whether direct and personal or by public invitation, and to enable the Secretary to grant rehearings, correct miscalculation and award addi *183 tional amounts. The amendments still left all claims to his sense of justice and equity.
Two cases upon which the relator relies, do not aid him. They depend on the construction of the particular statute. In
Work
v. Mosier,
Ness
v.
Fisher,
Lane
v.
Hoglund,
There is a class of cases in which a relator in mandamus has successfully sought to compel action by an officer who has discretion concededly conferred on him by law. The relator in such cases does not ask for a decision any particular way but only that it be made one way or the other. Such are
Louisville Cement Company
v.
Interstate Commerce Commission,
Our conclusion makes it unnecessary for us to consider the contention of the Government that the relator, here is estopped to urge the present claim by his acceptance of the award already made.
Reversed.
