parole violators who have more than one year left to serve and those who have less. He concludes that the distinction is wholly arbitrary and does not rationally serve any legitimate State policy. Because every statutory enactment carries a strong presumption of validity, the burden is on the attacking party to demonstrate its invalidity beyond a reasonable doubt
(Nettleton Co. v Diamond, 27 NY2d 182 , 193;
Fenster v Leary, 20 NY2d 309 , 314;
Matter of Van Berkel v Power, 16 NY2d 37 , 40). Courts will also indulge the presumption "that the Legislature has investigated and found the existence of a situation showing the need for or desirability of the legislation”, and will strike down a statute "only as a last unavoidable result”
(Matter of Van Berkel v Power, supra, p 40 ). Moreover, as the parties agree, the test to be applied on this equal protection challenge is whether the statute has "some rational basis”
(McGinnis v Royster, 410 US 263 , 270; see also,
Dandridge v Williams, 397 US 471 , 487). Subdivision 5 of section
803 of the Correction Law provides, in pertinent part, as follows: "Time allowances granted prior to any release on parole or prior to any conditional release shall be forfeited and shall not be restored if the paroled or conditionally released person is returned to an institution under the jurisdiction of the state department of correctional services for violation of parole, violation of the conditions of release or by reason of a conviction for a crime committed while on parole or conditional release. A person who is so returned may, however, subsequently receive time allowances against the remaining portion of his maximum or aggregate maximum term or period not to exceed in the aggregate one-third of such portion
provided such remaining portion of his maximum or aggregate maximum term or period is more than one year. ” [Emphasis supplied.] The italicized proviso was added by the Laws of 1969 (ch 270, §
2). Its purposes are thoroughly discussed in the memorandum of the division of parole in support of the bill (NY Legis Ann, 1969, pp 31-33). The memorandum indicates that the amendment aimed to restrict the rerelease of parole and conditional release violators who are returned to prison near the ends of their sentences. The memorandum points out that in the absence of some limitation on good time eligibility it would be possible for the violator to demand rerelease for an indefinite number of successively shorter periods of parole supervision. Such would still be true under present law if the one-year limitation were removed. Under section 70.40 (subd 1, par [b]) of the Penal Law, a prisoner under an indeterminate sentence "shall, if he so requests, be conditionally released * * * when the total good behavior time allowed to him, pursuant to the provisions of the Correction Law, is equal to the unserved portion of his maximum * * * term”. An indeterminate-term prisoner is eligible to accrue good time equal to one third of his maximum sentence (Correction Law, §
803, subd 1). Thus, were it not for the one-year limitation on good time eligibility, a parolee returned with six months to serve could qualify for rerelease after four months, after which he would be "under the supervision of the state board of parole” (Penal Law, § 70.40, subd 1, par [b]) for the remaining two months of his sentence. Without some limit on good time eligibility, there would come a point where the period of parole supervision would be so short that the Legislature could rationally find that its rehabilitative value no longer justified the cost. Thus, one justification for the challenged statute is purely economic. A second justification, also discussed in the division of parole memorandum cited, is disciplinary. Since the granting of parole or conditional release no longer interrupts the service of an indeterminate sentence, and since the parolee or conditional releasee no longer forfeits the "street time” served prior to the violation (Penal Law, § 70.40, subds 1, 3; cf.
