Petitioner seeks review of a final order of the Superintendent of the Oregon State Penitentiary which imposed a $100 fine for violation of a disciplinary rule. He contends, inter alia, that the fine is invalid. We agree. Watson v. OSP, 90 Or App 85, 750 P2d 1188 (1988).

The other claim of error has no merit.

Fine vacated; order otherwise affirmed.
