ISRAEL FINE vs. CONTRIBUTORY RETIREMENT APPEAL BOARD.

ABRAMS, J. The Contributory Retirement Appeal Board (CRAB) appeals from a decision of a judge in the Superior Court that the plaintiff's classification as a Group 4 employee subject to retirement at age sixty-five, G. L. c. 32, Section 3 (2) (g) (1986 ed.), violates the plaintiff's "constitutional right to equal protection under the law." The judge ordered the plaintiff's reassignment to Group 1 of the State employees' retirement system "with all statutory rights that flow therefrom." [Note 1] We transferred the case to this court on our own motion. We reverse.

The facts, which are not in dispute, are as follows. The plaintiff, Israel Fine, was born on August 1, 1915. At the time of the hearing, the plaintiff testified that he had been employed by the Registry of Motor Vehicles for twenty-nine years. On July 1, 1979, the plaintiff became a supervising hearing officer for the registry, pursuant to G. L. c. 90, Section 29 (1986 ed.). As a supervising hearing officer, the plaintiff conducted hearings; recommended the suspension or revocation of licenses or registrations; revoked or suspended licenses and registrations when necessary; initiated investigations of complaints of motor vehicle law violations; examined motor vehicle operators' records to determine appropriate action; interpreted court decisions; and answered inquiries from law enforcement officials concerning the status of motor vehicle operators. The plaintiff had no police powers and did not perform any hazardous duties.

On October 16, 1979, the State board of retirement notified the plaintiff that he had been placed in Group 4 for retirement purposes. A Group 4 employee must retire on the last day of the month in which he or she attains age sixty-five. The plaintiff knew at the time he was appointed supervising hearing officer that his appointment placed him in Group 4. [Note 2] The plaintiff appealed this classification to CRAB. In 1980, the division of hearings officers conducted a hearing for CRAB. Before the hearing officer issued her decision, the plaintiff filed a complaint in the Superior Court seeking a declaration as to the constitutionality of G. L. c. 32, Section 3 (2) (g), as applied to him, and an injunction against his involuntary retirement on August 31, 1980. The Superior Court issued the injunction pending the outcome of the plaintiff's appeal. The hearing officer thereafter issued findings and recommended that the plaintiff be classified as a member of Group 4 for retirement purposes, thereby affirming the decision of the board of retirement. CRAB accepted the hearing officer's findings of fact and recommendation.

The plaintiff sought judicial review of CRAB's decision in the Superior Court, pursuant to G. L. c. 30A, Section 14 (1986 ed.), [Note 3] claiming that his classification as a Group 4 employee deprived him of rights secured by the equal protection clause of the Fourteenth Amendment to the United States Constitution and by art. 10 of the Massachusetts Declaration of Rights. [Note 4] The judge agreed with the plaintiff's claim and ordered the plaintiff's classification as a Group 1 employee subject to mandatory retirement at age seventy.

In analyzing equal protection claims, this court has held that statutes which do not involve either a suspect group or a fundamental right only need be supported by a conceivable, rational basis. Aronson v. Commonwealth, ante 244, 254 (1987). Lee v. Commissioner of Revenue, 395 Mass. 527, 529-530 (1985). Blue Hills Cemetery, Inc. v. Board of Registration in Embalming & Funeral Directing, 379 Mass. 368, 371 (1979). See Massachusetts Bd. of Retirement v. Murgia, 427 U.S. 307, 312 (1976); New Orleans v. Dukes, 427 U.S. 297, 303 (1976). The plaintiff does not claim that his assignment to Group 4 involves a fundamental right or a suspect classification. See Blue Hills Cemetery, Inc., supra at 371 n.6. See also Murgia, supra at 313. Thus, the retirement classifications enacted in G. L. c. 32, Section 3 (2) (g), are constitutional unless the plaintiff proves that the statute "cannot be supported upon any rational basis of fact that reasonably can be conceived to sustain it." Sperry & Hutchinson Co. v. Director of the Div. on the Necessaries of Life, 307 Mass. 408, 418 (1940). See Klein v. Catalano, 386 Mass. 701, 707 (1982). See also Shell

Oil Co. v. Revere, 383 Mass. 682, 690 (1981); Zayre Corp. v. Attorney Gen., 372 Mass. 423, 432 (1977). The plaintiff has not met his burden.

The plaintiff argues that his classification as a Group 4 employee discriminates among similarly situated employees because the plaintiff's supervisor, the deputy registrar, as well as his immediate subordinates, all are assigned to Group 1 and thereby subject to retirement at age seventy. The plaintiff concedes that, unlike the supervising hearing officers, none of these employees conducts hearings on behalf of the registry. CRAB argues that, while perhaps not physically arduous, the duties of supervising hearing officers demand exacting levels of judgment and other mental capabilities which may decline with age. Assuring the high quality of supervising hearings officers is a legitimate, rational objective. CRAB concludes that the classification therefore has a rational basis. We agree. "A line drawn at [a specified age] eliminates the anguish, time, delay, expense, and embarrassment of the supervision and removal of older [hearing officers] of failing competence . . ." Apkin v. Treasurer & Receiver Gen., ante 427, 435-436 (1988).

Furthermore, CRAB argues that because the risk of disabling illness and death increases with age, mandatory retirement of supervising hearing officers at age sixty-five reduces delays in the administration of hearings at the registry, which might be caused by a supervising hearing officer's incapacity or death. Similarly, CRAB notes that a supervising hearing officer may be entrusted with overseeing a branch of the registry, and that early retirement therefore decreases the possibility that the operations of an entire branch office may be disrupted by the supervising hearing officer's disability or death. [Note 5] The statute has a rational basis, and therefore it is not unconstitutional. [Note 6]

The plaintiff asserts his Group 4 classification works invidious discrimination because his position as a supervising hearing officer is similar to that of a judge, and judges in the Commonwealth may serve until age seventy. "It is well settled that `a State retains broad discretion to classify as long as its classification has a reasonable basis,' " McCarthy v. Sheriff of Suffolk County, 366 Mass. 779, 786 (1975), quoting Graham v. Richardson, 403 U.S. 365, 371 (1971), and the fact that the Group 4 designation may be somewhat over-inclusive or under-inclusive or perhaps not entirely coextensive with similar positions is not fatal to an equal protection analysis. See Murgia, supra at 316. "A statute or ordinance is not rendered unconstitutional merely because the evidence of record suggests that the `ultimate efficacy' of achieving the statutory process is in question, or that the means to achieve the statutory end is rough, illogical or not the best available, or that the means stated in the statute is not perfectly consistent with the desired result. The success of the Legislature's choice need not be guaranteed" (footnotes omitted). Shell Oil Co. v. Revere, supra at 687.

The plaintiff suggests that Group 4 has no coherence. Group 4, in fact, includes a wide array of job descriptions. However, the fact that Group 4 is not entirely homogenous may be the result of an incremental process of legislative definition, [Note 7] which

Page 644

does not, in this case, offend against equal protection principles. "States are accorded wide latitude in the regulation of their local economies under their police powers, and rational distinctions may be made with substantially less than mathematical exactitude. Legislatures may implement their program step by step . . . in such economic areas, adopting regulations that only partially ameliorate a perceived evil and deferring complete elimination of the evil to future regulations" (citation omitted). New Orleans v. Dukes, supra at 303.

Accordingly, we conclude that the classification of the plaintiff as a Group 4 employee for retirement purposes is supported by a plausible, rational basis, and does not violate the plaintiff's rights to equal protection of the laws as guaranteed by the United States Constitution and by the Massachusetts Declaration of Rights. The judgment is reversed and this matter is remanded to the Superior Court for entry of a judgment affirming the decision of CRAB.

So ordered.
