UNITED STATES ex rel. DUNLAP v. BLACK, COMMISSIONER OF PENSIONS. UNITED STATES ex rel. ROSE v. SAME. UNITED STATES ex rel. MILLER v. SAME. ERROR TO THE .SUPREME COURT OF THE DISTRICT OF COLUMBIA. Nos. 991, 992, 993. Argued October 12, 1888. Decided October 22, 1888. The courts will not interfere by mandamus with the executive officers of the government in the exercise of their ordinary official duties, even where those duties require an interpretation of the law; no appellate power»being given them for that purpose. When an executive officer of the government refuses to act at all in a case in which the law requires him to act, or when, by special statute, or otherwise, a mere ministerial duty is imposed upon him, that is, a service which he is bound to perform without further question, if he refuses mandamus lies to compel him to his duty. The Commissioner of Pensions by receiving the application of a pensioner for an increase of his pension under the act of June 16, 1880, 21 Stat. ’ 281, c. 236, and by considering it and the evidence in support of it, and by deciding adversely to the petitioner, performs the executive act which , the law requires him to perform in such case; and the courts have no appellate power over him in this respect, and no right to review his decision. A decision of the Commissioner of Pensions adverse to the application of a pensioner for an increase of pension, under a statute granting an increase v in certain cases, being overruled by the Secretary of the Interior on the ground that the applicant comes under the meaning of the law granting the increase, and the Commissioner refusing to carry out the decision of his superior, the pensioner is entitled to a rule upon the Commissioner to show cause why a writ of mandamus should not issue to compel him to obey the decision of the Secretary of the Interior. ■These cases came here on writs of error to the Supremp Court of thé District of Columbia to review several judgments of that court refusing orders upon the Commissioner of Pensions to show cause why in- each case a writ of mandamus should not issue, requiring him to increase the pension of the petitioner.
