The relator, a patrolman in the police department of the city of New York, has been charged *176with “conduct unbecoming an officer and committing a criminal offense.” The specification is that on February-21, 1912, while in the sitting room of the thirty-ninth precinct station house he “ did take from the hip pocket of Patrolman Thomas J. Fitzpatrick * * * a 38 calibre regulation revolver, and by the careless handling of said revolver caused the same to be discharged, inflicting injuries on said Patrolman Fitzpatrick from which death ensued. ”
The relator and Fitzpatrick were brother officers and friends. Their tour of duty was over, and they went to the dormitory to change their clothes. Fitzpatrick showed the relator a revolver, and said that it was out of order. The relator pulled the trigger and found that it would not work. Fitzpatrick took the revolver back and put it, so the relator says, in his hip pocket. The relator then dressed and went down stairs, and found Fitzpatrick at the washstand. Protruding from the hip pocket was a revolver, which the relator supposed was the broken one. In fact it was another revolver. The broken one, if it had been put in that pocket at all, had been taken out and was in the pocket of a coat. The relator urged Fitzpatrick to hurry up; and going to the washstand, drew the protruding revolver out of his friend’s hip pocket and pulled the trigger. The next instant there was a loud report, and Fitzpatrick was shot. On the day following he died.
These facts are not disputed. The police commissioner held that they sustained the charge and dismissed the relator from the force. The Appellate Division, by a divided court, reversed his determination and directed that the relator be reinstated. The grounds of the decision are not stated in the order. A memorandum opinion states, however, that the determination is annulled on the ground that it is against the evidence. Since the evidence is not contradicted, this must mean that the relator’s conduct did not justify his dismissal.
*177In our opinion, the ruling of the Appellate Division is not to be sustained. We have nothing to do with the measure of the punishment inflicted on the relator. That is a matter for the commissioner. Our concern is solely with the question of the relator’s guilt. To sustain his reinstatement we must be prepared to hold that even a fine would have been unwarranted. That he did the acts charged against him in the specifications is not disputed. That those acts might properly be found by the commissioner to make out official delinquency does not seem to us to be doubtful. The relator shot and killed a brother officer by the careless use of a revolver. The discharge of loaded firearms in the innocent belief that they are not loaded, or that for some other reason they are harmless, is notoriously a frequent occasion of the loss of life and limb. The relator’s conduct would have been culpable in any one; it was doubly culpable in view of his position as a member of the police force. It is surely not too much to ask of the guardians of the lives and safety of the citizens of New York that they shall show a discretion and a caution that would have made this disaster impossible. We are not to overlook, moreover, the place in which it happened. There must be some limit to the horseplay allowed to officers within the walls of the station house. It does not seem unreasonable to hold that the limit has been passed when the horseplay involves the discharge of firearms with fatal consequences. At all events, it is not for the court, reversing the judgment of the commissioner, to pronounce such conduct consistent with order and discipline. The conduct itself was admitted. In determining that it was of such a nature as to require the punishment of the relator, to the end that the morale of the department might be preserved, the commissioner exercised a discretion not subject to judicial review.
It is true that under section 2140 of the Code of Civil Procedure the Appellate Division has the power in cer*178tiorari proceedings to determine “whether there was any competent proof of all the facts, necessary to be proved, in order to authorize the making of the determination,” and also, “if there was such proof, whether there was, upon all the evidence, such a preponderance of proof, against the existence of any of those facts, that the verdict of a jury, affirming the existence thereof, rendered in an action in the Supreme Court, triable by a jury, would be set aside by the court, as against the weight of evidence.” Broad as are the powers thus conferred, they are not so broad as to sustain the court’s ruling in this case. There was here neither conflict of proof as to the existence of any facts, nor conflict as to the inferences to be drawn from them. Accepting the relator’s own statement, and the most favorable deductions to be drawn from it, a case was none the less exhibited where the commissioner had the right to say that the discipline of the department demanded his dismissal. In this respect, the case is similar to that of People ex rel. Masterson v. French (110 N. Y. 494, 499). There the relator was intoxicated. He admitted his intoxication, but pleaded palliating circumstances. The General Term of the Supreme Court ordered his reinstatement. - In reversing that decision, tips court held that the case stood as if the relator “had pleaded guilty to the charge, and alleged the extenuating circumstances in mitigation of the punishment,” and that “when a dereliction of duty on the part of an officer has been proved, the sufficiency of an excuse therefor, presents no question of law or fact for the courts, but is addressed solely to the judgment and discretion of those who are primarily charged with the duty of maintaining the discipline and efficiency of the force.”
We conclude, therefore, that there was nothing in this record to call for the exercise by the Appellate Division of its discretionary powers; that the relator on the uncontradicted evidence was guilty of the acts stated in the *179specifications; and that the extent of the penalty to follow is not subject to judicial review.
The order of the Appellate Division should be reversed, and the writ dismissed, with costs to the appellant in all courts.
