Petitioner, the prevailing party in Cook v. Employment Division, 47 Or App 437, 614 P2d 1193, rev den 290 Or 157 (1980), moved for an award of attorney fees under ORS 183.495.1 Initially we denied the petition without stating reasons. Petitioner now moves for reconsideration, which we grant in order to explain our reasons.
The Employment Division, after receiving information that petitioner was not unemployed, undertook an investigation to determine whether petitioner was ineligible for benefits during a 19-week period in which he was reportedly employed in cutting and selling firewood. After a hearing, the agency assessed an overpayment of $2,261 against petitioner and imposed a penalty period of 26 weeks of ineligibility.
On judicial review on the merits, we decided that substantial evidence did not support the agency’s finding that petitioner was employed in 16 of the 19 weeks for which he was disqualified. We found that the evidence supported a finding that petitioner was employed part-time making deliveries of firewood in only 3 of the 19 weeks. 47 Or App at 443-44.
The present issue is whether the agency should be compelled to pay, out of its appropriated funds, petitioner’s attorney fees in successfully defending against a proceeding intended to fulfill the agency’s obligation to enforce the provisions of the Unemployment Compensation Act. We have not addressed this question, but recently we held that an award of attorney fees is inappropriate where the agency has acted as a disinterested adjudicatory tribunal. Davidson v. Employment Division, 51 Or App 219, 625 P2d 162 (1981). That principle is inapplicable here because the agency is an adversary of petitioner in enforcement proceedings. In Brown v. Adult and Family Services, 45 Or App 263, 608 P2d 197 (1981), we held that an award of attorney fees under ORS 183.495, given the legislative *310history and purpose of that provision, was not warranted where the agency action was not an arbitrary one. The theory is that an award of attorney fees would be justified if the agency acts in an arbitrary or capricious manner, because the risk of incurring that additional expense would tend to deter such action.
That rationale, however, is inappropriate when the agency is attempting to carry out its statutory duty of enforcing the Act it is established to administer. The risk of depleting its budget if, on judicial review, it is determined that the agency is wrong might tend to make the agency timorous in undertaking enforcement proceedings. Such a result would be contrary to the legislative scheme and, we believe, hot within the purpose underlying ORS 183.495 granting this court discretion in assessing such costs on judicial review. Frequently, evidence of disqualification for benefits is circumstantial and may depend on the credibility of witnesses, all of which may be viewed differently by different persons.2
*311We hold, therefore, that as a general proposition an award of attorney fees in agency enforcement proceedings is inappropriate. In doing so, we recognize that there may be extraordinary circumstances in a given case which would justify an exception to that general proposition. Such a case would be sui generis, and this case is not in that category.
Petition for reconsideration granted; the application for attorney fees is denied.3
