(2) If a dispute arises regarding the necessity or reasonableness of expenses charged to or allocated to the fee paid by an applicant, and if the dispute is not resolved by the directors of the affected agencies, the applicant may seek judicial review in circuit court of the amount of expenses charged or allocated as provided in ORS 183.480, 183.484, 183.490 and 183.500. If the applicant establishes that any of the charges or allocations are unnecessary or unreasonable, the amount found to be unnecessary or unreasonable shall be refunded to the applicant. The applicant shall not waive the right to judicial review by paying the portion of the fee or expense in dispute. [1997 c.449 §34]
