Opinion
In this case we review the constitutionality of Penal Code section 2900.5 1 which gives credit to persons convicted of felony offenses for time served in custody prior to the commencement of their prison sentence. Subdivision (c) of section 2900.5 makes the credit prospective only, limiting the application of the section to those persons who are delivered into the custody of the Director of Corrections on or after March *545 4, 1972, the effective date of the section. We have concluded that this limitation violates article I, sections 11 and 21, of the California Constitution and the equal protection clause of the Fourteenth Amendment in that it constitutes a legislative classification which is not reasonably related to a legitimate public purpose. We do not invalidate the entire statute, however, but only eliminate the discriminatory classification under subdivision (c) and thus extend the statutory benefits retroactively to those whom the Legislature improperly excluded.
*544 “(b) For the purposes of this section, credit shall be given only where the custody to be credited is attributable to charges arising from the same criminal act or acts for which the defendant has been convicted.
“(c) This section shall be applicable only to those persons who are delivered into the custody of the Director of Corrections on or after the effective date of this section [i.e. March 4, 1972].”
*545 In an information filed on October 22, 1970, petitioner was charged with murder (Pen. Code, § 187), kidnaping for ransom and reward (Pen. Code, § 209), and six counts of robbery (Pen. Code, § 211). In June 1971 he pleaded guilty to two counts of armed robbery and the other counts were dismissed. Petitioner was sentenced on each count to “the term prescribed by law,” with the terms to run concurrently. 2 Petitioner did not appeal and does not now attack the validity of the judgment of conviction; instead he petitions for habeas corpus seeking credit on his term for the 304 days he allegedly remained in custody between the time of his arrest and his receipt by the Department of Corrections. 3
Petitioner, having been delivered to the custody of the Director of Corrections before March 4, 1972, would not be entitled to credit under the provisions of Penal Code section 2900.5, for subdivision (c) of that section provides that its application is to be prospective only. However, petitioner invokes the basic guarantees of equal protection embodied in the Fourteenth Amendment to the United States Constitution and article I, sections 11 and 21, of the California Constitution, which prohibit the state from arbitrarily discriminating among persons subject to its jurisdiction, and require that classifications between those to whom the state accords and withholds substantial benefits must be reasonably related to a legitimate public purpose.
(Hayes
v.
Superior Court,
Petitioner is clearly a member of a class to whom the Legislature has denied a benefit granted to others. Although petitioner is serving terms with a maximum of life, denial of credit affects the date petitioner would first become eligible for parole. Therefore, we must determine whether the classification imposed by subdivision (c) is supported by a rational and legitimate state interest.
Initially, we point out that this case is not governed by cases (e.g.,
In re Estrada,
The People urge that an unconditional presentence jail credit for all present inmates will interfere with the effective operation of the Indeterminate Sentence Law. The People note that the primary purpose of the ISL is to allow the Adult Authority to mitigate punishment and provide rehabilitation on an individual basis. To achieve this purpose, the Adult Authority must undertake a case-by-case analysis of each prisoner, requiring ample opportunity to observe and evaluate that prisoner. (See
In re
Minnis,
*547 The People’s argument discloses, however, a misunderstanding of the manner in which presentence credit is to be applied under section 2900.5. As we interpret that section, the credit operates only to reduce the statutory maximum and minimum commitment terms, but ordinarily would not interfere with the Adult Authority’s discretion in setting the actual parole release date. The credit will advance the parole eligibility date, but would require premature release only in those cases in which the presentence credit combined with the actual prison terms fixed by the Adult Authority exceed the statutory maximum term applicable to the offense.* *** 5 And even though, in rare cases, the discretionary role of the Adult Authority may be curtailed, this result follows from the policy decision already made by the Legislature when it enacted section 2900.5, namely, that for purposes of credit, precommitment detention should be equated with postcommitment imprisonment. Although the state may have a legitimate interest in preserving the discretionary functions of the Adult Authority by differentiating between such detention and imprisonment, the state has waived that interest with respect to inmates received into state prison after March 4, 1972. Accordingly, the People must point to some legitimate public purpose served by excluding from the benefits of section 2900.5 all prisoners received before that time. 6
We do not find persuasive the People’s speculation that the Legislature may have made section 2900.5 prospective under the premise that only recently had rehabilitative facilities at county jails advanced sufficiently to justify granting a credit on prison sentences. As we explained above, such a credit normally would not interfere with the Adult Authority’s discretionary function in determining rehabilitation. Moreover, nothing in the *548 language of section 2900.5 supports such a theory, and the People have furnished us with no empirical data disclosing any such improvement in jail facilities.
Contrary to the People’s assertion in this respect, our holding is consistent with the rationale of the recent decision of the United States Supreme Court in
McGinnis
v.
Royster,
Even if McGinnis had concerned a question of retroactivity it still would not be controlling inasmuch as it dealt with a different kind of credit. McGinnis involved a potential 10 days a month “good-time” credit awarded as a bonus for good conduct and efficient performance of duty while in prison. It did not involve credit for time actually spent in jail, which credit was already specifically provided for by New York law. 7
The People also contend that the prospective application of the presentence jail credit is justified by the state’s legitimate purpose in avoiding unnecessary burdens upon the administration of justice. The People assume *549 that either the Adult Authority or the courts would experience great difficulty in applying the credit to all persons without regard to the date of their prison commitment. Yet the burdens predicted by the People appear illusory. 8
First of all, many of the difficulties posited by the People will not arise since we hold that section 2900.5 must be applied to all felony convictions, and not only to those in which presentence detention occurred as a result of indigency and inability to post bail. 9 Specifically, under our holding, it will be unnecessary to determine whether the person seeking credit was in fact indigent or whether he was otherwise entitled to bail. Furthermore, it does not appear that ascertaining the amount of credit due will constitute an unreasonable burden. Questionnaire forms with regard to “indigency credit” (see fn. 9, ante), have already been prepared by the Department of Corrections and are currently being distributed to inmates and parolees. With slight modification, these forms could be adopted for use in complying with this decision. When completed these forms could be forwarded to the *550 appropriate county sheriff’s office for factual confirmation of presentence jail time. Thereafter, only a simple ministerial adjustment would be required by the Adult Authority so that its records reflect the presentence time served. 10
A final argument offered by the People to justify the limitation of subdivision (c) is that many negotiated pleas may have been agreed upon taking into consideration the period of presentence incarceration. This argument is not persuasive even assuming it may have been a factor in some negotiated pleas. For the most part the presentence jail time would be insubstantial in relation to the statutory punishment.
Having thus concluded that the prospective limitation in section 2900.5, subdivision (c), is invalid, we must consider the validity of the remainder of that section. It is the general rule that although a provision or part of an act may be unconstitutional and beyond the power of the Legislature to enact, the entire act may not be void. “ ‘[Ujnconstitutional provisions will not vitiate the whole act, unless they enter so entirely into the scope and design of the law, that it would be impossible to maintain it without such obnoxious provisions.’ ”
(In re King, supra,
Thus, we conclude that the credit under section 2900.5 should be extended to those incarcerated or on parole for felony offenses regardless of the date of their commitment to state prison. We hereby direct the Adult Authority to take appropriate steps to inform petitioner and all other persons under its custody and supervision of the availability of that credit, to ascertain the amount of credit due and to adjust its records accordingly.
Wright, C. J., Tobriner, J., Mosk, J., and Sullivan, J., concurred.
I dissent. Petitioner is not denied equal protection of the law merely because the statutory right to presentence credit is restricted to those delivered to prison
after
the effective date of the legislation. A
constitutional
rule of criminal procedure is not applied retroactively by the United States Supreme Court unless it goes to jurisdiction in the traditional sense or is so fundamental to the guilt-determining process that its observance probably would have resulted in acquittal.

But even assuming arguendo that limiting section 2900.5 to prospective application requires a “rational and legitimate state interest,” the majority supplies one. In seeking to distinguish cases involving “the application to previously convicted offenders of statutes lessening the
punishment
for a particular offense,” the majority concedes that “[t]he Legislature properly may specify that such statutes are prospective only, to assure that penal laws will maintain their desired deterrent effect by carrying out the original prescribed punishment as written.”
(Ante,
p. 546.) Petitioner will become eligible for parole consideration almost a year early if he is given the presentence credit he claims.
(Ante,
pp. 545-546.) Eligibility for parole consideration is as integral to punishment by imprisonment as length of sentence. For a life prisoner like petitioner, the date he becomes eligible for parole is of paramount importance.

v.
State of North Carolina
(4th Cir. 1971)
Finally, if proposed reforms must be weighed by the Legislature in light of this court’s insistence that the consequences of change shall extend to the past as well as the future, “progressive” legislation will likely be stifled. As a matter of fact, section 2900.5 was not limited to prospective application when it was originally introduced in the 1971 Regular Session as As *553 sembly Bill No. 1237. 5 One well may wonder, therefore, whether the Legislature would have created the right to presentence credit if it had realized it was facing an all-or-nothing choice.
McComb, J., concurred.
Notes
Section 2900.5 provides: “(a) In all felony convictions, either by plea or by verdict, when the defendant has been in custody in any city, county, or city and county jail, all days of custody of the defendant from the date of arrest to the date on which,' the serving of the sentence imposed commences, including days served as a condition of probation in compliance with a court order, shall be credited upon his sentence, or credited to any fine which may be imposed, at the rate of not less than twenty dollars ($20) per day, or more, in the discretion of the court imposing the sentence. If the total number of days in custody exceeds the number of days of the sentence to be imposed, the entire sentence shall be deemed to have been served. In any case where the court has imposed both a prison sentence and a fine, any days to be credited to the defendant shall first be applied to the sentence imposed, and thereafter such remaining days, if any, shall be applied to the fine.
The term prescribed for armed robbery is from five years to life. (Pen. Code, § 211.) The counts to which petitioner pleaded guilty also recited that petitioner was “armed . . . within the meaning of Penal Code sec. 12022.5.” That section imposes an additional five-year minimum term of imprisonment for persons who “use” a firearm during an offense, and petitioner’s sentence was later “clarified” to include a finding that petitioner was armed and used a firearm during the offenses. Although petitioner has in prior proceedings contended that he did not knowingly plead guilty to use of a firearm under section 12022.5, that question is not now before us.
Under Penal Code section 2900 the term of imprisonment fixed by the judgment in a criminal action commences to run only upon the actual delivery of the defendant into the custody of the Director of Corrections at the place designated by the Director of Corrections as a place for the reception of persons convicted of felonies.
According to exhibits filed by the People, the Adult Authority is presently applying presentence credits to reduce both the statutory maximum- and minimum sentences defined in the commitment, and to reduce the minimum eligible parole release date. If petitioner’s contentions are accepted, presentence credits, would be applied in the same manner to those persons convicted of a felony and delivered into the custody of the Director of Corrections before March 4, 1972.
Neither would a retroactive credit necessarily affect the parole termination date of prisoners currently on parole in this state. The parole term is fixed by the Adult Authority to reflect the period of parole supervision deemed appropriate for the parolee to demonstrate his readiness for complete discharge of Department of Corrections custody; that period does not inevitably extend throughout the entire maximum term specified for the particular offense. Rather, as we have said, the goals of the parole system can best be achieved by the liberation of a prisoner on parole at the earliest period permitted by law and when on a consideration of the merits of each individual case, parole ought to be granted in the judgment of the board.

Only in the exceptional case where there is some irreconcilable discrepancy between the facts claimed by an inmate or parolee and those found by the sheriff would it be necessary to burden the courts with resolution of the issue.
The test voiced both by the United States Supreme Court and this court for determining whether a constitutional ruling should be applied retroactively calls for the consideration of three criteria: (1) the purpose of the new rule, (2) the extent of reliance upon the old rule, and (3) the effect retroactive application would have on the administration of justice.

The fact that “[t]he People herein do not contend that retroactive application of section 2900.5 would interfere with the foregoing legitimate public purpose” (ante, p. 546) does not excuse such interference. Although the Attorney General in fact argued vigorously and persuasively that a number of rational and legitimate state interests support purely prospective application of section 2900.5, his failure to do so would have been excusable in light of petitioner’s express disavowal, both in his briefs and at oral argument, that he was relying on section 2900.5 in claiming a constitutional right to presentence credit.
As originally introduced, the bill contained the following language: “This section shall be applicable to all persons in custody on the effective date of this act.”
