delivered the opinion of the court:
Victor Colletti, an inmate at the State Penitentiary, Joliet, with our permission, filed an original petition for writ of habeas corpus with this court. The respondent is the warden of the penitentiary, Frank J. Pate.
The parties agree on the facts in this case. Petitioner was committed to the penitentiary in 1954 to serve three concurrent sentences. The first sentence was for a term of one to fifteen years, while the second and third were for terms of two to fifteen years. The judgments specifically provided that all three sentences were to be served concurrently. Petitioner has earned good-time credits and under the regulations of the Department of Public Safety has served in full his second and third sentences and is entitled to be discharged therefrom, however he is not eligible for discharge from the first sentence until September 15, 1964. A different schedule of good-time credits applies to the first sentence. The crimes involved in the second and third sentences were committed in 1951; parenthetically, petitioner originally received probation in connection with these offenses which was revoked in 1954 and he was sentenced. The crime involved in the first sentence was committed in 1953. On January 30, 1952, the Department of Public Safety, pursuant to section 1 of the act relating to diminution of sentences (Ill. Rev. Stat. 1951, chap. 108, par. 45,) revised the schedule of good-time credits, decreasing the yearly allowance for all sentences in excess of eight years. The revised schedule applies only prospectively; see our opinion People ex rel. Johnson v. Pate,
Petitioner contends that he should be released from his first sentence as well, because the revised schedule of good-time credits is invalid and the previous schedule still obtains. Petitioner has served the maximum of his first sentence less good-time credits under the former schedule and he argues that he is entitled to be discharged.
Illinois initiated the practice of reducing a convict’s sentence because of good behavior in prison in 1872 (Act of March 19, 1872, Laws of 1871-72, p. 294; Rev. Stat. 1874, chap. 108, pars. 45-49.) The original act contained five sections. The first section prescribed a schedule of yearly credits on account of good time; one month was allowed for the first year and the allowance was increased for each succeeding year until the sixth year when six months was authorized. The annual allowance of good timo remained constant at six months thereafter. The second section prescribed forfeiture of earned good-time credits because of infractions of prison rules; a schedule of time to be forfeited for each infraction was likewise a part of that section. Section 3 provided that consecutive sentences were to be considered for good-time purposes as one continuous sentence. Section 4 provided for the allowance of good time on sentences being served at the time of the adoption of the act. Section 5 authorized the Governor to restore a convict’s rights of citizenship although he violated prison rules.
The original good-time statute was changed in 1925. Section 1 was amended while sections 2 and 4 were repealed. Amended section 1 provided: “The Department of Public Safety is authorized and directed to prescribe reasonable rules and regulations for the diminution of sentences on account of good conduct, of persons heretofore and hereafter convicted of crime, who are confined in the State penal and reformatory institutions.” No schedule of good-time credits was furnished. Section 1 as amended in 1925 is in the same form today. Ill. Rev. Stat. 1963, chap. 108, par. 45.
Petitioner contends, and respondent does not dispute, that between 1925 and 1941 good-time credits were allowed convicts under the schedule of repealed section 1 of the act of March 19, 1872. In 1941 the Department of Public Safety formalized this practice by promulgating a regulation adopting the repealed 1872 statutory schedule. On January 30, 1952, the Department of Public Safety promulgated a new schedule of good-time credits, reducing the annual credit for years of a sentence in excess of eight; three months in the ninth year and four months for each year thereafter. The difference in good-,time credits that a convict might earn serving a fifteen-year maximum sentence, as in the case of petitioner, under the prior and present schedule is one year and three months. It is this extension of which petitioner complains; he contends that the legislature could not constitutionally delegate the duty of fixing good-time credits; that if such duty is delegable the 1925 amendment was ineffectual to do so, because it gave no standards to guide the Department of Public Safety in prescribing good-time credits and lastly if the duty is delegable and there was an effective delegation, the 1952 regulation is invalid because it is arbitrary and discriminatory to convicts like petitioner serving sentences in excess of eight years.
The nature of good-time credit has not been defined by the courts of this State; in People ex rel. Johnson v. Pate,
Not everything affecting a criminal penalty becomes an essential part thereof. The opportunity for parole is an important aspect of a criminal sentence, yet we recently held that parole is a matter of grace which could constitutionally be changed retroactively by the legislature. (People ex rel. Kubala v. Kinney,
The duty to prescribe a schedule of good-time credits may be validly delegated to the Department of Public Safety, as we have just held, but an administrative agency cannot constitutionally be vested with authority to determine what the law shall be. Intelligible standards to guide the agency in its rule-making authority must be supplied by the legislature. (People v. Warren,
Lastly petitioner argues that the regulation decreasing good-time credits on longer sentences is invalid, because it is discriminatory and arbitrary. The basis for this charge is that the change adversely affects petitioner and other convicts serving long sentences. An administrative regulation, like a statute, enjoys a presumption of validity and that presumption is not rebutted by the mere showing that petitioner and others in a like situation are adversely affected thereby.
The schedule of good-time credits as promulgated by the Department of Public Safety is valid. The writ of habeas corpus must therefore be quashed.
Writ quashed.
