Mr. Chief Justice Taft,

after stating the case, delivered the opinion of the court.

The President acted under the 118th Article of War, which provides in part (39 Stat. 619, 650, 669) that,

“No officer shall be discharged or dismissed from the service except by order of the President or by sentence of a general court-martial; and in time of peace no officer shall be dismissed except in pursuance of the sentence of a court-martial or in mitigation thereof.”

*544 This article is only a reenactment of the 99th Article of War contained in the Revised Statutes, § 1342. Both are, therefore, to be read with § 1230, Rev. Stats., which is as follows:

“ When any officer, dismissed by order of the President, makes, in writing, an application for trial, setting forth, under oath, that he has been wrongfully dismissed, the-President shall, as soon as the necessities of the service may permit, convene a court-martial, to try such officer on the charges on which he shall have been dismissed. And. if a court-martial is not so convened within six months from the presentation of such application for trial, or if such court, being convened, does not award dismissal or death as the punishment of such officer, the order .of dismissal by the President shall be void.”

Appellant claims that by the failure to grant him a court-martial, his dismissal under § 1230- was rendered void ab initio and that he is still a Colonel.

The first question is whether he ceased to be a member of 'the Army by the nomination and confirmation of another which filled the complement of officers allowed by law in his rank. It is clear from the reasoning of this court in the case of Blake v. United States, 103 U. S. 227, that the words* “ by order of the President,” in § 1230, Rev. Stats., supra, refer to a dismissal by the President alone, and do not include the removal of an officer by the appointment and confirmation of his successor.

Before the Civil War there was no restriction upon the President’s* power to remove an officer of the Army or Navy. The principle that the power of removal was incident to the power of appointment was early determined by the Senate to involve the. conclusion that, at least in absence of restrictive legislation, the President, though he could not appoint without the consent of the Senate, could remove without such consent in the case of any officer whose tenure was not'fixed by the Constitution. *545 The first legislative restriction upon this power was enacted March 3, 1865, by the very, provision we are here considering (13 Stat. 489), which subsequently became § 1230, Rev. Stats. Thereafterj on July 13, 1866, Congress took away altogether the power of the President to dismiss an officer of the Army or Navy in time of peace, except in pursuance^ of a court-martial sentence or in commutation thereof(c. 176, 14 Stat. 92). After that, in the controversy between President Johnson and the Senate, the tenure of office act was passed which cut down the power of the President to remove civil officers. Act of March 2, 1867, c. 154, 14 Stat. 430. The validity of these acts has never been directly passed on by this court in any case. The question has been expressly saved. Parsons v. United States, 167 U. S. 324, 339.

While, thus,' the validity and effect of statutory restrictions upon the power of the President alone to remove officers of the Army and Navy and civil officers have been the subject of doubt and discussion, it is settled, McElrath v. United States, 102 U. S. 426; Blake v. United States, 103 U. S. 227; Keyes v. United States, 109 U. S. 336; Mullan v. United States, 140 U. S. 240, that the Presidént with the consent of the Senate may effect the removal of an officer of the Army or Navy by the appointment of another to his place, and that none of the limitations in the statutes affects his power of removal when exercised by and with the consent of the Senate. Indeed the same ruling , has been made as to civil officers. Parsons v. United States, 167 U. S. 324.

The question here, then, is whether the Senate joined the President in his removal of the appellant. . That the President intended to separate him from the Army is, of course, plain. What are we to infer from the Senate’s action in confirming appointments by the President which filled the complement of officers of the rank of appellant allowed by law? The appointment of Lieut. Colonel *546 Robert Smith was made two weeks after the announcement in General Orders of the dismissal of appellant and was made to confer the rank as of February 14th, the day after appellant was dismissed. The appointment did not say, as is usual in such cases, vice Wallace dismissed; but the facts of record in the War Department and in General Orders leave no doubt of the intention of the President and the Department in that regard. This raises the inquiry what we should presume as to the knowledge of the Senate in the matter. We can take judicial notice of the fact that nominations to office sent to the Senate are usually referred to the appropriate committee for investigation and 'report. In this case, the nomination would have been sent to the Military Committee which considers each appointment and is, of course, charged with the duty of inquiring into the éxistence of a vacancy to which an appointment can be made, as well as into its wisdom and propriety. Communication between the Department and the Committee dealing with such appointments is easy and frequent. We must presume, therefore, in the absence of any showing to the contrary, that the Senate was advised of the facts in respect to the nomination of Lieut. Colonel Smith and that it intended to supply the vacancy occasioned by the dismissal of appellant. Otherwise we must conclude that the Senate Committee was recommending, and the Senate was deliberately voting, confirmation of a nomination to a place for which there was no provision by law. We must assume that the confirming authorities knew the legal complement of Colonels in the Quartermaster Corps and how many they had already confirmed for that office. They must, therefore, have made inquiry and been assured as to the vacancy which would make Colonel Smith’s nomination and rank from February 14, 1918, proper.

It is urged that if the dismissal of appellant was rendered void ab initio, as contended, the effect was to restore *547 him to office, and he was entitled to pay although the lawful complement of officers had been exceeded. To sustain this view, Quackenbush v. United States, 177 U. S. 20, is cited. It fails entirely to do so. On the contrary, it. shows that in order to authorize pay for an officer whose place has been filled by nomination and confirmation of the Senate, there must be special legislative authority.

This is conclusive and renders it unnecessary to consider whether appellant lost his right to apply for a court martial under § 1230 by waiting five months, a question not free from doubt, considering the exigencies and need for dispatch in time of war. See Norris v. United States, ante, 77, and Nicholas v. United States, ante, 71.

The judgment of the Court of Claims is

Affirmed.
