KISTLER, P.J.
The Board of Parole and Post-Prison Supervision and the Department of Corrections appeal the grant of a writ of habeas corpus requiring the Lane County Sheriff to release petitioner from custody. The trial court held that, because petitioner's sentence had expired, the Board did not have authority to revoke his parole and return him to custody. We reverse.
The Lane County Sheriff took petitioner into custody on September 6, 2000, because he possessed a controlled substance, because he was in contempt of court, and because the Board had revoked his parole. Petitioner sought administrative review of the Board's revocation order. He argued, among other things, that, because his underlying sentence had expired, the Board lacked authority to revoke his parole. The Board upheld the revocation, finding that his sentence had not expired.
On December 4, 2000, petitioner filed a petition for habeas corpus in Lane County Circuit Court. The court issued the writ, and the Board and the Department of Corrections intervened and filed a motion to dismiss. They argued that petitioner could not seek habeas relief because another adequate remedy was available: Petitioner could seek judicial review of the Board's administrative order affirming the decision to revoke his parole. The trial court disagreed with that procedural argument and also with intervenors' contention that petitioner still had three years to serve on his sentence. It accordingly entered a judgment ordering the sheriff to release petitioner.
Intervenors have appealed, and the initial question on appeal is whether the fact that petitioner could have sought judicial review of the Board's order precludes him from seeking habeas. See Tiner v. Clements, 173 Or.App. 168, 169, 20 P.3d 262, rev. den. 332 *676 Or. 305, 27 P.3d 1045 (2001) (reasoning that a writ of habeas corpus is available only if no other adequate remedy exists).[1] A petitioner may seek habeas relief only if "there is no other timely remedy available to him [or her]" and if there is a "need for immediate judicial scrutiny" of the claim. Gage v. Maass, 306 Or. 196, 204, 759 P.2d 1049 (1988). Here, ORS 144.335(1) permits petitioner to seek judicial review of the Board's action and is an adequate alternative remedy. Cf. Frady v. Morrow, 169 Or.App. 250, 255, 9 P.3d 141 (2000).[2] Additionally, a lieutenant in the sheriff's office had filed an affidavit stating that petitioner was in custody on the parole violation and also on a separate charge of possession of a controlled substance. Thus, petitioner would remain in custody on the separate charge, and would not be entitled to immediate release, even if he prevailed in this case. Petitioner is not entitled to habeas corpus relief on this record.[3]
Reversed.
NOTES
[1]  We note that ORS 34.330(4) now provides that a person may not prosecute a writ of habeas corpus if he or she

"is eligible to seek judicial review of a final order of the State Board of Parole and Post-Prison Supervision under ORS 144.335 but the person fails to seek judicial review of the order in a timely manner."
This subsection, however, was not enacted until 2001, see Or. Laws 2001, ch. 661, § 2, and there is no evidence that the legislature intended it to apply retroactively to persons, such as petitioner, who petitioned for habeas corpus relief before its effective date.
[2]  In Frady, the state argued that the petitioner's ability to seek administrative review of the Board's order setting his release date meant that a timely remedy, other than habeas corpus, was available to him. 169 Or.App. at 255, 9 P.3d 141. We did not dispute the premise of that argument. Rather, we rejected the state's argument because petitioner alleged that he had applied for and exhausted his administrative remedies. Id. We note that, because the petitioner in Frady could not have sought judicial review of the order denying his release date, the precise question presented here was not presented in Frady.
[3]  We have considered petitioner's other arguments and reject them without discussion.
