In general, after an offender has been released on parole, the Oklahoma Department of Corrections may issue a warrant when a violation of parole has been established. This process is initiated by an offender’s parole officer, not by the Parole Board. If the parole officer wishes to pursue revocation proceedings, a probable cause (preliminary hearing) is conducted by the Oklahoma Department of Corrections staff. If probable cause is found (by a preponderance of the evidence), the offender is then scheduled for an Executive Revocation Hearing before the Parole Board Administrative Law Judge (ALJ). After passage of State Question 762 the revocation hearing process has been divided into a process for violent offenses and non-violent offenses.
