Petitioner, an inmate in the Oregon State Penitentiary, seeks review of a final order of the Superintendent that placed him in disciplinary segregation until he complied with an order to enter administrative segregation.1 We conclude that imposing a potentially unlimited confinement in disciplinary segregation is unauthorized and, therefore, reverse and remand.

The facts are not in dispute. On his final day in disciplinary segregation for a disciplinary violation, petitioner refused to enter the administrative segregation unit voluntarily. A misconduct report was immediately filed that alleged that he had failed to comply with a valid order. That evening, petitioner received notification that a hearing concerning the misconduct report would be held the following day. When he did not appear at the hearing, the Disciplinary Committee ruled that his non-appearance constituted a waiver of his right to at least 24 hours’ notice of the hearing and his right to present evidence. The committee, after accepting the misconduct report, found that petitioner had refused to comply with a valid order and that he had continued to refuse to comply with the order. It therefore held that he had violated Disciplinary Rule 10,2 and the committee recommended that he

“be retained in [the Disciplinary Segregation Unit] until such time that he complies with the order.”

The Superintendent approved the committee’s findings and recommendations.

Petitioner contends that the committee lacked authority to place him in disciplinary segregation for an indefinite period. A period of confinement in disciplinary segregation must be set in accordance with OAR 291-105-053, which lists only discrete periods of time for which an inmate may be confined. It does not explicitly or implicitly allow confinement *9for an indefinite period. The Superintendent therefore erred in adopting the committee’s recommended unlimited confinement.3

Reversed and remanded for reconsideration.
