delivered the Opinion of the Court.
The petitioner, Larry Wayne White (White), appeals from the district court’s order denying his pro se petition for a writ of habeas corpus. In his petition, White alleges that the Colorado State Parole Board (Parole Board) erred in denying his application for re-parole and violated his constitutional rights by requiring him to participate in a sex offender treatment program (SOTP). The district court held that White did not allege that he was illegally detained and denied the petition without holding an eviden-tiary hearing. We affirm.
I
White entered a plea of guilty to rape on September 24,1975, and was sentenced to an indeterminate sentence of commitment— from a minimum of one day to a maximum of life imprisonment — pursuant to the Colorado Sex Offenders Act. § 16-13-203, 8A C.R.S. (1986). In September, 1985, White was paroled. Subsequently, his parole was revoked because he committed a new offense.
II
A writ of habeas corpus is a proper remedy to determine whether a defendant is being unconstitutionally denied the opportunity to be considered for parole. Naranjo v. Johnson,
White contends an evidentiary hearing is necessary because his confinement is invalid and his fundamental constitutional rights are being denied.
A
Implicit in the district court’s decision to deny White’s petition for habeas corpus is the fact that White failed to establish a prima facie ease that he is being detained unlawfully. White’s petition for habeas corpus does not set forth a prima facie case of invalid confinement.
White alleges a number of facts which he contends prove his confinement is 'unlawful. He asserts: (1) his inmate file contains unfavorable and inaccurate information which is based on the opinion of incompetent medical personnel; (2) he is being denied proper treatment because the Department of Corrections (DOC) has made faulty transfer decisions; and (3) the Parole Board’s decision that he should not be re-paroled is incorrect and based on arbitrary and capricious standards.
White’s first contention relates to his classification as a sex offender and the information the DOC maintains in White’s personnel file. The determination of how to monitor an offender’s progress and what, if any, weight the Parole Board chooses to place on the evidence before it are matters solely for the Parole Board’s consideration and discretion. Thiret v. Kautzky,
White also challenges the DOC’s transfer decisions. Habeas corpus relief is not an available remedy to contest prison transfer and placement decisions. Deason,
White’s final assertion is that the Parole Board erred in refusing to re-parole him. Because White committed a sex offense, the consideration of his application for parole is a matter entrusted solely to the discretion of the Parole Board. See § 17-2-201(5)(a), 8A C.R.S. (1986); Thiret,
All three of White’s grounds for granting an evidentiary hearing allege that the Parole Board abused its discretion. We have recognized that the Parole Board’s discretion is plenary and is not subject to judicial review. In re Question Concerning State Judicial Review,
B
White has also alleged that his constitutional rights were violated and, as a result, an evidentiary hearing is required. One of the Parole Board’s reasons for not re-paroling White is the Board’s belief that he needs to obtain more treatment, including participation in a SOTP. White asserts that the Parole Board cannot require him to participate in a SOTP as a requirement for parole. A state is not required to establish a parole system. If a state chooses to do so, it is free to establish and define conditions that must be complied with in exchange for parole. Greenholtz,
There is no constitutional or inherent right of a convicted person to be conditionally released before the expiration of a valid sentence. Greenholtz,
Similarly, the requirement that he participate in a SOTP does not violate the Ex Post Facto Clause even though the program did not exist when White was sentenced. It is true that punishment cannot be retroactively increased. Aue v. Diesslin,
White also contends that requiring him to enter into a SOTP violates the Equal Protection Clause because the program forces him to serve a longer period of imprisonment after his parole violation than other inmates who have violated the conditions of their parole. Because White is a sex offender, he is not similarly situated to other inmates. See People v. Kibel,
Because White is not entitled to parole, the requirement that he attend a SOTP before he receives the privilege of parole does not violate the Due Process, Ex Post Facto, or Equal Protection Clauses of the Constitution.
Ill
White has not alleged any facts that demonstrate invalid confinement or infringement on a fundamental constitutional right. White’s petition does not establish a prima facie case for relief and the district court did not err in denying White’s petition without a hearing. We therefore affirm the district court’s order denying White’s petition for habeas corpus.
Notes
. White filed a pro se petition for writ of habeas corpus which challenged the revocation of parole. The district court denied White's petition without an evidentiary hearing. We reversed the district court's decision and remanded with directions to hold an evidentiary hearing. White v. District Court,
On September 2, 1992, the United States District Court for the District of Colorado denied a petition for habeas coipus that contested the parole revocation. White v. McKinna, No. 91-Z-650 (D.Colo. September 2, 1992). White has appealed the ruling to the United States Court of Appeals for the Tenth Circuit where the matter is pending.
. We specifically stated: "If the statutory duties of the Board have been performed ... then it would appear that [the defendants'] claims are that the Board abused its discretion in denying their applications for parole. There would be no judicial review of such denial in state courts of Colorado.” In re Question Concerning State Judicial Review,
. White also contends he is being required to incriminate himself in violation of the protection guaranteed by the Fifth Amendment to the Constitution. White has already been convicted of being a sex offender. If he were to admit he is a sex offender. White would not be subject to any additional prosecution. See Hoffman v. United States,
