I think the commission was authorized to adopt the provision contained in subdivision 4 of rule 29 of the Buffalo municipal civil service rules, adopted in February, 1917, which requires as a condition of eligibility to enter a promotional examination, that the person desiring promotion must have been continuously employed for a specified period (in the police department twelve months) immediately preceding such examination, in a next lower position, the duties of which are such as would naturally and properly tend to fit him for the duties of the position to which he seeks promotion. (Matter of Ricketts, 111 App. Div. 669.)
I do not think that this is contrary to the spirit' of rule 30 of the Buffalo police department, adopted by the council, which provides that Vacancies in the positions of captains and lieutenants shall be filled by appointment of a member *297of the force. This does not mean that all members of the force are entitled to take the examination, but only such as are permitted under the reasonable rules promulgated by the civil service commission. Experience and seniority in service are elements to be considered upon the question of fitness to promotion. The Civil Service Law (Consol. Laws, chap. 7 [Laws of 1909, chap. 15], § 16) so declared.
Neither do I think that the commission is required to adopt the classification of the council. It is true that government and discipline in the department is to be prescribed by the council. (Laws of 1914, chap. 217, § 250.) But that does not prevent the commission from making rules for the classification of the offices, and for appointments and promotions therein and examinations therefor. Express authority is given the commission to do so. (Civil Service Law, § 11, as amd. by Laws of 1916, chap. 357.)
I think the application of the detective sergeants to enter the examination for captain, without having been a lieutenant, should have been denied.
As to the desk sergeants, I am of the opinion that the grading of the commission made under rule 29 excluding desk sergeants should not stand. Merely because a patrolman is detailed as a desk sergeant and not doing patrol duties immediately preceding the examination, should not deprive him of the right to take the examination for promotion which he would be entitled to take if he were doing patrol work.
It can hardly be assumed that only inefficient patrolmen are appointed desk sergeants. The presumption is quite to the contrary if the patrolman has attained to the rank of the first grade. While it is true that a good clerk may not make a good patrolman, it does not follow that a good patrolman may not also make a good clerk, and if the good of the service require that he be detailed as a desk sergeant, that should not bar him from promotion to the position of lieutenant to which he would have been eligible if he had remained on patrol duty. If that were so a detail at any time within the year immediately preceding the promotional examination would bar a patrolman from such promotion, however efficient his services as a patrolman may have been, and well fitted he may be for the position of lieutenant.
*298I am, therefore, of the opinion that the order granting the writ as to the desk sergeants should be affirmed, with costs, but that the order denying the writ as to the detective sergeants should be reversed and the writ dismissed.
Ail concurred.
In the first and second cases orders reversed and writs dismissed, with costs. In the third and fourth cases orders affirmed, with costs.
