delivered the opinion of the court:
This is an appeal from a judgment of the circuit court of Cook county granting the writ of mandamus on petition of James J. Miller, appellee, by which it was commanded that appellants place the name of said Miller upon the police *417pay-roll of the city of Chicago as lieutenant of police, with the right to continue thereon and receive a salary the same as prior to the time of his removal. After various amendments to the pleadings the case was heard by the court, jury being "waived, on the petition as amended, answer and replication thereto, and the court on November 25, 1907, entered a judgment and order in favor of appellee and granted the writ as above stated. From this judgment an appeal was prayed to this court.
Appellants asked the trial court to hold the following proposition of law: “The provision of section 12 of the Civil Service act providing that charges against an officer or employee in the classified service shall be investigated by or before the civil service commission, or some officer or board appointed by said commission to conduct said investigation, is not void as delegating a judicial power, contrary to the provisions of the constitution of" the State of Illinois.” The trial judge made the following notation on this proposition : “Denied because that part of section 12 which authorizes the commission to delegate judicial power to an officer or board is unconstitutional.” The case is broúght directly to this court because the constitutionality of this provision of the statute is questioned.
That part of the provision of section 12 of the City Civil Service act now in force in the city of Chicago involved in this questipn reads as follows: “No officer or employee in the classified civil service of any city who shall have been appointed under said rules and after said examination, shall be removed or discharged except for cause, upon written charges and after an opportunity to be heard in his own defense. Such charges shall be investigated by or before said civil service commission, or by or before some officer or board appointed by said commission, to conduct such investigation. The finding and decision of such commission or investigating officer or board, when approved by said commission, shall be certified to the appointing offi*418cer, and shall be forthwith enforced by such officer,” etc. Hurd’s Stat. 1905, p. 395.
This court has held in People v. Kipley, 171 Ill. 44, that the Civil Service act here in question is not unconstitutional, as delegating judicial power to the civil service commissioners; that the legislature has the power to control municipalities created by it, and may direct how officers shall be elected or appointed by such cities and how they may be removed. This court in the recent decision of City of Aurora v, Schoeberlein, 230 Ill. 496, held that section 12 in .the act of 1903, providing for the appointment of police and fire commissioners in certain cities, (Hurd’s Stat. 1905, p. 390,) which gave such commissioners pow.er to remove the officers in the department under them for cause, was not unconstitutional, as delegating judicial power to such board. The powers given the police and fire commissioners under that act are very similar to those given to the civil service commissioners under this act. The removal of an officer is not the exercise of a judicial power, as there is no such thing as title or property in a public office. Donahue v. County of Will, 100 Ill. 94; Stern v. People, 102 id. 540.
The charges against appellee were not heard, in the first instance, by the civil service commission, but by a trial board of the police department designated by the civil service commission for that purpose, in accordance with its rules. Appellee was charged with being absent from duty without permission of the general superintendent or his commanding officer. On the hearing before the trial board these charges were found to be true, and the following finding was made: “Upon investigation of within charges we find said James J. Miller guilty of being absent from duty without permission of the general superintendent of police or his commanding officer, and decide that he be discharged from his position of lieutenant- of police,” etc., which finding of the trial board was thereafter approved by the civil service commission.
*419As we understand the ruling of the trial court on the proposition of law in question, it was held that the part of section 12 of said Civil .Service act which authorizes the civil service commission to allow the investigation to be conducted before an officer or board appointed by it, rather than by the commission itself, was a delegation of judicial power and therefore unconstitutional. If the civil service commission, in hearing such charges, would not exercise judicial functions, it is difficult to see how it delegates judicial functions to the board or officer designated "to investigate the charges, when such board or officer exercises no greater power in the investigation than would the commission itself. Indeed, this trial board did not exercise as great a power as the commission, as it only had authority to hear the charges and recommend action, subject to approval or disapproval by the commission. Said section 12 specifically provides that these investigations may be conducted by such boards or officers, and the reasoning of this court in People v. Kipley, supra, and City of Chicago v. People, 210 Ill. 84, is conclusive as to the constitutionality of this provision. A very similar provision in the New York Civil Service law has been upheld by the highest court of that State. People ex rel. v. Board of Police Comrs. 93 N. Y. 97.
The evidence before the trial board was taken down in shorthand and was shown on this hearing not to have been written up and read by the civil service commission before the recommendation of the trial board was acted upon, and it is insisted that all this ¡evidence must be read by the commission in order to comply with the law and justify the removal. We cannot agree with this contention. The intent of the law is that the civil service commission shall exercise its own judgment in reaching a conclusion as to whether the recommendation of the trial board shall be approved or disapproved. The law does not require, however, that the evidence before the trial board shall be taken down *420in shorthand, and even if such evidence be taken down, the law does not require that it shall be written up and read by the commission before it makes its finding on the recommendation. The civil service commission is not required to review in any specific manner the evidence before the trial board, call witnesses, notify the accused or give him an opportunity to be heard before the commission itself, previous to approving or disapproving the finding of the trial board. What examination or investigation was made by the civil service commission is not disclosed by the record, but it must be presumed to have been in accord with the law unless the contrary be shown. It may be noted that in this case the trial board was composed of two members of the civil service commission—a majority of the latter body.
The petition of appellee alleges that appellee was denied the right of having counsel before the trial board. The evidence does not support this contention and appellee does not here insist upon this point.
It is most earnestly insisted that the charges against the appellee were not proven before the trial board and that he was removed without cause. This court, in City of Chicago v. People, supra, stated (p. 92) : “After a trial is held, in the manner pointed out by the statute, before the proper board, and evidence is taken tending to show the guilt of the person charged, we are of the opinion that the action of the civil service commission, based on the finding of the board, is final and not reviewable by the courts. * * * The statute does not contemplate a review of the action of the commission which results in the discharge of an officer or employee of the city, after a lawful trial before the proper board, by any tribunal whatsoever.”
Appellee contends that the decision just referred to is not conclusive here, because there was not in the case now at bar a proper trial. We held in Wilcox v. People, 90 Ill. 186, that where the law has vested quasi judicial power (such as that of removal of civil service employees here in *421question) even in subordinate administrative officers, the courts will not inquire whether an officer has acted within the power and will not attempt to substitute their own judgment or discretion for that of the officer, and will not supply any other conditions to the exercise of his discretionary power than those the law has provided. Where acts and duties necessarily call for the exercise of judgment and discretion on the part of an officer, body or person at whose hands performance is required, mandamus will not lie to direct how such discretion shall be exercised. (High on Ex. Legal Remedies,—3d ed.—sec. 24; 2 Spelling on Ex. •Relief, sec. 1384.) Even granting that the courts have power, by mandamus, to review the findings of such civil service commissioners where their discretionary power has been grossly abused or exercised for selfish and unworthy motives or in an arbitrary or capricious manner, which we do not here decide, yet there is nothing in this record which tends to show that the discretion of the trial board, as approved by the civil service commission, was not exercised in a proper manner.
Under the decisions of this court we think the finding of the trial board, approved by the civil service commission, as shown by this record, cannot be set aside by the courts. (City of Chicago v. People, supra; Kenneally v. City of Chicago, 220 Ill. 485; Kammann v. City of Chicago, 222 id. 63.) The contention of appellee in this regard, if upheld, would practically amount to a review of the evidence by the courts in all investigations conducted by the civil service commission or under its direction. This is not the law. As was said in City of Aurora v. Schoeberlein, supra, (p. 504,) such a review by the courts “would be the exercise of executive powers, which the separation of departments of the government precludes the court from exercising.”
Other points have been discussed in the briefs, but what we have already said in the opinion disposes of these questions and renders unnecessary further discussion thereon.
*422For- the reasons heretofore set out the circuit court erred in entering the judgment restoring the appellee to the police roster as lieutenant of police.
The judgment will be reversed and the cause remanded, with directions to the trial court to dismiss the petition.
Reversed and remanded, with directions.
