OPINION OF THE COURT
Mercure, J.The premise underlying this proceeding is that Retirement and Social Security Law § 381-b (e), as amended by Laws of 1988 (ch 759), which required that petitioner be retired from his position as Assistant Deputy Superintendent with the Division of State Police at the conclusion of the year in which he attained age 57, violates the Nonimpairment Clause of the NY Constitution (NY Const, art V, § 7)* as applied to him. We disagree and accordingly affirm Supreme Court’s judgment dismissing the petition.
Petitioner began his 33-year service with the Division of State Police in 1963. In 1969, he became a member of a 20-year special pension and retirement program for State Police personnel, created by Laws of 1969 (ch 336) and codified as Retirement and Social Security Law § 381-b (e). That retirement program subjected petitioner, who then held the position of Trooper, to a mandatory retirement age of 55 (see, Retirement and Social Security Law § 381-b [former (e)]). An almost immediate amendment to Retirement and Social Security Law § 381-b (former [e]) provided for a mandatory retirement age of 60 for those holding certain high-ranking positions within the Division of State Police, including the position of Assistant Deputy Superintendent (L 1969, ch 470). Finally, Retirement and Social Security Law § 381-b (e) was again amended in 1988 so as to eliminate the distinction between classes of members and to fix a uniform mandatory retirement age of 57 for all members (see, L 1988, ch 759). Petitioner turned 57 in 1996 and was mandatorily retired effective December 30, 1996 in accordance with Retirement and Social Security Law § 381-b (e).
*237The record establishes that petitioner attained the position of Assistant Deputy Superintendent in 1994, the year in which he turned 55. There is no question that, had there been no amendment to Retirement and Social Security Law § 381-b (e) subsequent to 1969, petitioner’s attainment of one of the positions specified in Retirement and Social Security Law § 381-b (former [e]) prior to the end of 1994 (when he would have been otherwise mandatorily retired at age 55) would have granted him the advantage of the enhanced mandatory retirement age of 60 provided for in Laws of 1969 (ch 470). Therefore, there can be no question that, viewed in the light of petitioner’s circumstances as they subsequently unfolded, the amendment to Retirement and Social Security Law § 381-b (e) by Laws of 1988 (ch 759) had the effect of limiting the term of petitioner’s potential employment with the Division of State Police by three years. Obviously, had they been available to petitioner, those additional three years of service would have enhanced petitioner’s ultimate pension benefits.
Contending just that, petitioner argues that Laws of 1988 (ch 759) diminished or impaired his contractual rights in the pension system and thereby violated the Nonimpairment Clause. In Cook v City of Binghamton (48 NY2d 323), however, the Court of Appeals considered and rejected an essentially identical claim. There, the plaintiffs argued (as here relevant) that 1977 amendments to General Municipal Law § 207-a, which permitted disabled firemen to be involuntarily retired in advance of the general mandatory retirement age, violated the Nonimpairment Clause by impermissibly impairing and diminishing the benefits of their membership in a public retirement system (see, Cook v City of Binghamton, supra, at 332). In rejecting that argument, the Court stated as follows: “It is long settled, however, that the fact that there can be no constitutional impairment of pension system benefits does not create a constitutional right to stay in public employment. To do this would place the regulation of public employment beyond the control of any authority, which certainly was not intended by our Constitution” (id., at 332 [emphasis supplied] [citation omitted]). To the very same end, and employing the rationale that an “expectation of remaining in public employment * * * is not within the scope of protection afforded by the Nonimpairment Clause”, this Court rejected the contention that Laws of 1984 (ch 661) violated the Nonimpairment Clause by causing a disabled firefighter to receive pension benefits that were lower than those he would otherwise have received *238had he remained employed to age 70 (Lake v Regan, 135 AD2d 312, 314, appeal dismissed 72 NY2d 840, lv denied 72 NY2d 807).
We are unpersuaded by the dissent’s efforts to distinguish these controlling cases and reliance upon earlier and, in our view, less closely analogous authority. Notably, the Court of Appeals has already observed that, unlike Cook v City of Binghamton (supra), the cases of Public Empls. Fedn. v Cuomo (62 NY2d 450 [involving the refund of retirement contributions upon retirement]), Kleinfeldt v New York City Employees’ Retirement Sys. (36 NY2d 95 [involving the rate of compensation part of the retirement formula]) and Birnbaum v New York State Teachers Retirement Sys. (5 NY2d 1 [involving the calculation of the annuity portion of the retirement allowance]) all “involved changes directly related to the retirement benefit” (Matter of Lippman v Board of Educ., 66 NY2d 313, 317 [emphasis in original]). Brown v New York State Teachers Retirement Sys. (25 AD2d 344, affd on opn below 19 NY2d 779) is a case, as is the present one, where the constitutional challenge was properly rejected.
We conclude that the subject change in the mandatory retirement age was enacted to further a legitimate public policy goal (see, Lake v Regan, supra) and that, as in Cook v City of Binghamton (supra) and Lake v Regan (supra), petitioner merely seeks to extend the term of his public employment, thereby effecting but a “minor and entirely incidental” influence on his retirement benefits (Cook v City of Binghamton, supra, at 332). We therefore affirm Supreme Court’s judgment dismissing the petition.
NY Constitution, art V, § 7 provides, in relevant part, that: “membership in any pension or retirement system of the state * * * shall be a contractual relationship, the benefits of which shall not be diminished or impaired.”
