   THORNTON, J.

In this petition for judicial review of the decision of the disciplinary committee of the Oregon State Penitentiary petitioner appeals from his conviction of Major Rule 3 — “Present in an Unauthorized Area.”

Petitioner alleges that the disciplinary committee violated Rule IY(5)(d) regarding the admissibility of evidence obtained through an unidentified informant. Additionally, he contends that there was insufficient evidence to support the committee’s decision.

Respondent concedes that Rule IY(5)(d) was not complied with, however it argues that no prejudice resulted.

We agree. The evidence of motivation was not necessary to the proof of the violation charged, namely, that petitioner was present in an unauthorized area. The committee’s finding of fact made no reference to petitioner’s motivation and made no conclusion based thereon. We are of the opinion that the other evidence in the record was sufficient to support the finding of the guilt. Bonney v. OSP, 16 Or App 509, 519 P2d 383, aff'd 270 Or 79, 526 P2d 1020 (1974).
