Petitioner seeks review of a final order of the Superintendent of the Oregon State Penitentiary that found him guilty of violating a disciplinary rule and imposed, inter alia, a $100 fine. He contends that there is not sufficient evidence to support the finding that he had violated a disciplinary rule. There is. However, we agree with respondent’s concession that the fine is invalid. Watson v. OSP, 90 Or App 85, 750 P2d 1188 (1988).

Fine vacated; otherwise affirmed.
