Oregon Revised Statutes Procedure in Criminal Matters Generally § 144.232

(a) Notwithstanding ORS 137.010 or the rules of the Oregon Criminal Justice Commission, the State Board of Parole and Post-Prison Supervision may sanction an offender to the supervision of the local authority for a maximum period of 180 days for any supervision violation. The sanction may be imposed repeatedly during the term of post-prison supervision for subsequent supervision violations.

(b) After release under this section, the board may at any time return the offender to prison and require the offender to submit to a psychiatric or psychological examination as provided for in ORS 144.226. If the board finds that the offender's dangerousness has returned and cannot be adequately controlled with supervision and mental and physical health treatment, or that resources for supervision and treatment are not available to the offender, the board may defer the offender's release from prison for an indefinite period of time. An offender returned to prison under this paragraph is entitled to periodic reviews for possible release to post-prison supervision as provided by subsection (3) of this section.
