Petitioner seeks review of an order which found that he had violated an institutional rule. He was ordered to serve one month in segregation and to pay a $50 fine.

His only contention on review is that the superintendent had no authority to assess a fine. The state concedes error. Watson v. OSP, 90 Or App 85, 750 P2d 1188 (1988).

Reversed as to fine; otherwise affirmed.
