The commissioner of water supply, gas and electricity of the city of New York appeals from an order of peremptory mandamus directing the restoration of the petitioner to the position of inspector of pipes and castings in the department of water supply, gas and electricity. The petitioner, having passed a civil service examination, held a position in the competitive class of the classified civil service by appointment, on November 24, 1923, to the position of inspector of pipes and castings. On December 20, 1927, the petitioner was arrested on a charge of homicide committed in New Jersey and, this having come to the attention of the commissioner, he was suspended on that date without pay. On May 8, 1928, the petitioner was declared insane by the courts of New Jersey and was committed as an insane person to the Trenton Hospital. For this reason, on May 17, 1928, he was “ dropped from the rolls of the department,” without the filing of any formal charges and without notice to him, by an interoffice memorandum signed by the commissioner and his place in the department was filled by another employee. On April 8, 1930, the petitioner, having been found to have recovered his sanity and judicially declared to be sane by the courts of New Jersey, was tried for the homicide committed in December, 1927, He was acquitted by the jury, apparently upon the ground that he was insane at the time of the commission of the alleged crime. He thereupon returned to New York city and about six months thereafter, on October 4, 1930, executed and filed an application for the return of accumulated salary deductions paid by him into the New York city employees’ retirement system during the period of his employment by the city. In that application he stated that he “ was dismissed, from my position as Inspector of Pipes & Castings, Department of Water Supply, Gas & Electricity, Bureau Inspection *385on the day of Dec., 1927, and am not now in City service." Upon this application the board of estimate and apportionment on December 5, 1930, authorized the refund to the petitioner of the accumulated deductions amounting to $414.47. On December 17, 1930, the petitioner for the first time seems to have questioned the propriety of his dismissal, for on that date he addressed a letter to the commissioner demanding to know the reason for having been dropped from the department in May, 1928. There followed, in January, 1931, an interview with an official of the municipal civil service commission concerning the petitioner’s dismissal from the service, the substance of which is in dispute. On May 7, 1931, an earlier application for mandamus was made, which on June 4, 1931, was denied upon the ground of laches. In July, 1931, upon motion of the petitioner, the order denying that application was resettled so as to deny it without prejudice to a new application explaining the petitioner’s delay in making the original application for relief. On December 9, 1931, the petition here was verified.
We think it is unnecessary to consider whether the petitioner could be dismissed from the department upon the ground of insanity, and, if so, whether he was entitled to notice and a hearing upon specified charges as provided in section 22 of the Civil Service Law. All these were objections which the petitioner was" at liberty to waive (People ex rel. McLaughlin v. Police Commissioners, 174 N. Y. 450), and it affirmatively appears that he waived any such objections here. With full knowledge of the facts he acquiesced in the dismissal and thereby is precluded from asserting its invalidity. We agree with the court at Special Term that laches cannot be imputed to a person who is insane (People ex rel. Jennings v. Johnson, 161 App. Div. 625), and we, accordingly, exclude from consideration the petitioner’s failure to take action until he was restored to sanity and was acquitted on April 8, 1930, after an absence from municipal employment of about two years and three months. But we find no adequate explanation for his conduct from then until December 17, 1930, when, for the first time, he appears to have questioned the propriety of the action of the commissioner in dropping him from the rolls of the department. It is true that the petitioner says that during this period his health Was impaired and that he was advised by his physician not to report to work until he felt able to do so. But this would not have prevented him, during a period of eight months, from making some protest, verbal or written, against a dismissal which he now claims to have been without authority of law. It does not explain his action on October 4, 1930, in making formal application, under section 1709 of the Greater New York Charter, for refund of salary *386deductions paid into the New York city employees’ retirement system, upon allegations that he had been dismissed from the department in December, 1927, and was not in the city service. The petitioner’s conduct in this respect is entirely inconsistent with his present claim that he has never been dismissed because the action of the commissioner in “ dropping him from the rolls ” was equivalent merely to temporary suspension without pay. When the petitioner filed his formal application for a refund of salary deductions, he must have intended to waive whatever invalidity attended his dismissal from the department and to regard his separation from the city service as valid and permanent. Upon no other theory could he have filed the application under section 1709 of the charter which provides for refunds only where a member has been separated from the city service; upon no other theory could the board of estimate and apportionment have authorized it to be made. The conceded facts, therefore, do not entitle the petitioner to relief, and the application for an order of mandamus, either peremptory or alternative, should have been denied.
The order appealed from should be reversed, with twenty dollars costs and disbursements, and the motion denied.
