The Virginia Parole Board shall by regulation divide each calendar year into such equal parts as it may deem appropriate to the efficient administration of the parole system. Unless there be reasonable cause for extension of the time within which to review and decide a case, the Board shall review and decide the case of each prisoner no later than that part of the calendar year in which he becomes eligible for parole, and at least annually thereafter, until he is released on parole or discharged, except that upon any such review the Board may schedule the next review as much as three years thereafter, provided there are ten years or more or life imprisonment remaining on the sentence in such case. Such reviews shall include a live interview of the prisoner by a Board member or a staff member designated by the Board. Such interviews may be conducted in person or by videoconference or telephone at the discretion of the Board. Absent imminent death of the prisoner or other extraordinary circumstances, which shall be documented by the Board in the prisoner’s file, the Board shall not grant parole to any prisoner who has not received a live interview within the prior calendar year. Notwithstanding any other provision of this article, in the case of a parole revocation, if such person is otherwise eligible for parole, the Board shall review and decide his case no later than that part of the calendar year one year subsequent to the part of the calendar year in which he was returned to a facility as provided in § 53.1-161. Thereafter, his case shall be reviewed as specified in this section. The Board, in addition, may review the case of any prisoner eligible for parole at any other time and may review the case of any prisoner prior to that part of the year otherwise specified. In the discretion of the Board, interviews may be conducted by the Board or its representatives and may be either public or private.
