delivered the opinion of the court:
These consolidated appeals bring before us the constitutionality of the mandatory parole provisions of the Unified Code of Corrections (Ill. Rev. Stat. 1975, ch. 38, par. 1001 — 1—1 et seq.). In each case defendant was released upon parole after serving the maximum term of his indeterminate sentence of imprisonment. His parole was subsequently revoked for a violation of a condition, and he was reincarcerated.
In each case defendant applied to the circuit court for a writ of habeas corpus. In cause No. 48431 the circuit court of Massac County held the statutory provisions invalid, and granted the writ. The State filed an appeal to this court. In cause No. 48432 the circuit court of Saline County held the provisions constitutional, and denied defendant’s petition. Defendant appealed to the Appellate Court for the Fifth District, that appeal was transferred here, and the two appeals were consolidated. The public defender of Cook County was given leave to file a brief amicus curiae. He urges the invalidity of the mandatory parole provisions.
Section 5 — 8—1(e) of the Unified Code of Corrections (Ill. Rev. Stat. 1975, ch. 38, par. 1005 — 8—1(e) provides:
“Every indeterminate sentence shall include as though written therein a parole term in addition to the term of imprisonment. Subject to earlier termination under Section 3 — 3—8, the parole term shall be as follows:
(1) for murder or a Class 1 felony, 5 years;
(2) for a Class 2 felony, or a Class 3 felony, 3 years;
(3) for a Class 4 felony, 2 years.”
Section 3 — 3—9(a) of the Code (Ill. Rev. Stat. 1975, ch. 38, par. 1003 — 3—9(a)) provides in pertinent part:
“(a) If prior to expiration or termination of the term of parole, the parolee violates a condition of parole, the Parole and Pardon Board may:
(3) revoke the parole and reconfine the person for a term computed in the following manner:
(i) the recommitment shall be for that portion of the imposed maximum term of imprisonment or confinement which had not been served at the time of parole, less the time elapsed between the parole of the person and the commission of the violation for which parole was revoked, and, in addition, if the person was sentenced on or after the effective date of this Act, the parole term ***.”
We pointed out in People v. Wills (1975),
It is urged without supporting authority that to give the Parole and Pardon Board, an administrative agency, the power to enlarge the period of commitment is to give the Board judicial power in violation of the separation of powers clause of the Illinois Constitution of 1970. But the Board is not imposing a “second” sentence upon defendant for his original crime. The judge imposes the sentence. The sentence to a mandatory parole is a part of the original sentence by operation of law. What causes recommitment to prison of a defendant who is on parole is the revocation of his parole. What causes the revocation is defendant’s violation of one or more conditions of his parole. (See United States v. Rich (8th Cir. 1975),
These appeals differ markedly from People v. Montana (1942),
It is also suggested that the mandatory parole provisions violate due process in that there is no judicial review of revocation by the Board. While the United States Supreme Court held in Morrissey v. Brewer (1972),
The judgment of the circuit court of Massac County is accordingly reversed, and the cause is remanded with directions to deny the petition for a writ of habeas corpus. The judgment of the circuit court of Saline County is affirmed.
48431 — Reversed and remanded, with directions.
48432 — Judgment affirmed.
