Dismissal of petition challenging BPT determination that defendant suffered from a severe mental disorder and that, as a condition of his parole, he be treated by the Department of Mental Health is affirmed. Once the time has past for the inmate to request a hearing following the initial commitment determintation, and proceedings have been instituted to extend the commitment, the inmate may not contest his mental state at the time of the underlying offense, but rather, he may only challenge the BPT's determination of his current mental status.
