245 U.S. 308 (1917)
DUNCAN TOWNSITE COMPANY
v.
LANE, SECRETARY OF THE INTERIOR.
No. 51.
Supreme Court of United States.
Argued November 15, 1917.
Decided December 10, 1917.
ERROR TO THE COURT OF APPEALS OF THE DISTRICT OF COLUMBIA.
*309 Mr. Charles H. Merillat, with whom Mr. Charles T. Kappler was on the brief, for plaintiff in error.
Mr. Assistant Attorney General Kearful for defendant in error.
MR. JUSTICE BRANDEIS delivered the opinion of the court.
This is a petition for a writ of mandamus brought in the Supreme Court of the District of Columbia to compel the Secretary of the Interior to restore the name of Nicholas Alberson, deceased, to the rolls under the Choctaw-Chickasaw Agreement of July 1, 1902 (32 Stat. 641), and to execute and record a patent for land described in an allotment certificate issued in his name by the Dawes Commission.
Under that act only the names of persons alive September 25, 1902, were entitled to entry on the rolls. Alberson had died before that date. The entry of his name and the issue of the certificate were procured by fraud and perjury. These facts, now conceded, were established by the Commission to the Five Civilized Tribes; and the Secretary of the Interior upon recommendation of the Commission removed Alberson's name from the rolls, held the certificates for cancellation and allotted the land to others. Notice of the hearing before the Commission was given to Alberson's administrator and attorney of record, but not *310 to the relator, who had, under the Oklahoma law, recorded the deed assigning the certificates and was in actual possession of the premises. The certificates had issued on or before April 7, 1906. The notation removing Alberson's name from the rolls was made January 11, 1908. The relator purchased the certificates before January 11, 1908, for value in good faith without knowledge of the fraud or notice of the proceedings for cancellation hereinbefore referred to. The Supreme Court entered judgment for the relator, commanding issue and record of the patent, but making no order in respect to restoring Alberson's name to the rolls. The relator acquiesced in the judgment; but on writ of error sued out by respondent the judgment was reversed by the Court of Appeals (44 App. D.C. 63); and the relator brings the case here on writ of error.
The nature of the Choctaw-Chickasaw Agreement[1] and the rights incident to enrollment and allotment have been frequently considered by this court. Enrollment confers rights which cannot be taken away without notice and opportunity to be heard. Garfield v. Goldsby, 211 U.S. 249. Certificates of allotment, like receiver's receipts under the general land laws, entitle the holder to exclusive possession of the premises; Act of July 1, 1902, § 23, 32 Stat. 641-644; United States v. Detroit Lumber Co., 200 U.S. 321, 337-8. But enrollment and certificates may be cancelled by the Secretary of the Interior for fraud or mistake, Lowe v. Fisher, 223 U.S. 95; because although the equitable title had passed, Michigan Land and Lumber Co. v. Rust, 168 U.S. 589, 593, the land remains subject to the supervisory power of the Land Department, Knight v. Lane, 228 U.S. 6, until issue of the patent, United States v. Wildcat, 244 U.S. 111, unless under the statute the power expires earlier by lapse of time. Ballinger *311 v. Frost, 216 U.S. 240. Under § 5 of the Act of April 26, 1906, c. 1876, 34 Stat. 137, the legal title can be conveyed only by a patent duly recorded. Brown v. Hitchcock, 173 U.S. 473, 478. The provision in § 23 of the Act of July 1, 1902, that "allotment certificates issued by the Commission to the Five Civilized tribes shall be conclusive evidence of the right of any allottee to the tract of land described therein" has relation to rights between the holder and third parties. The title conferred by the allotment is an equitable one, so that supervisory power remained in the Secretary of the Interior.
We are not required to decide whether (as suggested in Lowe v. Fisher, 223 U.S. 95, 107) the power to remove Alberson's name from the rolls had, because of § 2 of the Act of April 26, 1906, expired before the Secretary acted. For the Supreme Court of the District did not order the name restored, and its judgment was acquiesced in by the relator. The claim which the relator makes in this court rests wholly upon the fact that the relator was a bona fide purchaser for value. But the doctrine of bona fide purchaser for value applies only to purchasers of the legal estate. Hawley v. Diller, 178 U.S. 476, 484. It "is in no respect a rule of property, but a rule of inaction." Pomeroy, Equity Jurisprudence, § 743. It is a shield by which the purchaser of a legal title may protect himself against the holder of an equity, not a sword by which the owner of an equity may overcome the holder of both the legal title and an equity. Boone v. Chiles, 10 Pet. 177, 210.
Mandamus is an extraordinary remedial process which is awarded, not as a matter of right, but in the exercise of a sound judicial discretion. It issues to remedy a wrong, not to promote one; to compel the performance of a duty which ought to be performed, not to direct an act which will work a public or private mischief or will be within the *312 strict letter of the law but in disregard of its spirit. Although classed as a legal remedy, its issuance is largely controlled by equitable principles.[1a] The relator having itself only an equity seeks the aid of the court to clothe it with the legal title as against the United States, which now holds both the legal title and the equity to have set aside an allotment certificate secured by fraud. A writ of mandamus will not be granted for such a purpose. See Turner v. Fisher, 222 U.S. 204. The judgment of the Court of Appeals is
Affirmed.
