Legislation adopted in 1986 authorizes the parole board to retain in custody those inmates considered likely to commit a serious offense before the end of their sentence. Inmates released on mandatory supervision are not permitted to earn remission again if their first release is revoked. To identify high-risk inmates, the Correctional Service will review all cases involving certain specified offenses. A determination of risk potential will consider the following: persistent pattern of violent behavior, psychiatric or psychological evidence that there is a likelihood of committing violent offenses of causing death or serious injury, reliable information that the inmate is planning to commit a violent offense, and the availability of supervision programs offering adequate protection to society. Cases to be reviewed should be referred to the parole board 6 months prior to the possible mandatory supervision release date. Inmates who are ordered to be detained may appeal that decision.
