Opinion by
The question before the Court in this appeal is the constitutionality of the Act of December 16, 1965, *256 P. L. 1115, §2, 16 P.S. §4710(b) (Supp. 1967) which reduced to fifty-five the age at which Allegheny County policemen are entitled to receive a retirement allowance after twenty or more years of service. Prior to the enactment of the Act of December 16, 1965, Allegheny County policemen, like all other employees of that county, were entitled to receive retirement allowance after twenty or more years of service only after the age of sixty, Act of July 28, 1953, P. L. 723, §1710, as amended, Act of May 31, 1955, P. L. Ill, §1.
Plaintiff William H. Geary was born on December 9, 1908 and by 1966 had been employed continuously as a member of the police force of Allegheny County for a period in excess of thirty-three years. On May 11, 1966, at the age of fifty-seven, Geary notified the Retirement Board of Allegheny County of his intention to retire voluntarily on June 30, 1966 and made application for a retirement allowance under the provisions of the Act of December 16, 1965. The retirement board denied plaintiff’s application on June 20, 1966 and two days later the instant action of mandamus was instituted by Geary in the Court of Common Pleas of Allegheny County to compel the board to grant his application. The court of common, pleas dismissed plaintiff’s complaint on the ground that the Act of December 16, 1965 violates federal and state constitutional guarantees of due process 1 and prohibitions of the impairment of the obligation of contracts. 2
In support of this conclusion the court below and the retirement board here rely on the opinions of this Court in
Eisenberger v. Harrisburg Police Pension Comm'n,
“1. An employe who has complied with all conditions necessary to receive a retirement allowance can *258 not be affected adversely by subsequent legislation which changes the terms of the retirement contract.
“2. An employe who has not attained eligibility to receive a retirement allowance may be subject to legislation which changes the terms of the retirement contract if the change is a reasonable enhancement of the actuarial soundness of the retirement fund.
“3. An employe who has not attained eligibility to receive a retirement allowance may not be subject to legislation which changes the terms of the retirement contract if the change does not reasonably enhance the actuarial soundness of the retirement fund.” (Footnote omitted.)
The retirement board’s attack on the Act of December 16, 1965 relies chiefly on the formulation of principles in the
Harvey
case. Since the Act reduces the actuarial soundness of the Allegheny County Retirement Fund, the board urges that it “changes the terms” of the retirement contracts of employees presently and in the process of becoming eligible to receive payments within the meaning of the first and third paragraphs of the
Harvey
summary. In other words, the board argues that the Act of December 16, 1965 deprives all nonpolice members of the fund of vested rights and impairs the obligation of their contracts merely because it theoretically reduces the certainty of payment to them.

While it is arguable in the abstract that this theoretical possibility is comprehended by the phrase “changes the terms” used by the Court in
Harvey,
we
*259
believe that reference to the facts of the decisions which
Harvey
attempted to generalize shows that what the Court meant by the phrase was a concrete detriment to the employee rather than the conjectural disadvantage of reduced actuarial soundness. Moreover, the fact that the Court concluded that an enhancement of the actuarial soundness of a fund was sufficient to prevent an increase in the age or length-of-service requirement for employees not yet eligible from being unconstitutional does not mean, as the retirement board suggests, that a decrease in actuarial soundness is by itself sufficient to constitute a deprivation of vested rights or an impairment of contractual rights. Thus, bearing in mind the strong presumption in favor of the constitutionality of legislation, e.g.,
Milk Control Com’n v. Battista,
In this appeal the retirement board also takes the position that the Act of December 16, 1965 is unconstitutional because it unfairly discriminates against nonpoliee employees participating in the Allegheny County Retirement Fund. Relying on the equal protection clause of the Fourteenth Amendment to the Constitution of the United States as well as the prohibition of “special” laws in Article III, §7 of the Constitution of Pennsylvania, the board urges that there is no rational basis for permitting policemen to retire five years earlier than other county employees. We agree with the conclusion of the court below which rejected the board’s argument in this regard. As we have just pointed out in
Baxter v. Philadelphia,
Judgment reversed.

U. S. Const. Art. I, §10; Pa. Const. Art. I, §17.
Appellees also rely on general language in
Retirement Bd. v. McGovern,
It is certainly worth, noting that the court below,- after hearing actuaries testify for each side, concluded that while the Act of December 16, 1965 reduced the actuarial soundness of the retirement fund, “in all probability no employee, not a policeman, retiring in the future, would find his pension reduced even if the act were given effect.” It is also worth noting that the number of policemen participating in the fund is less than two percent of the total number of Allegheny County employees participating.
