ORS § 305.285
Whenever any property tax matter is appealed to the Department of Revenue, Oregon Tax Court or Supreme Court, and during the pendency of the appeal, no appeal is filed for a subsequent year or years, the taxpayer may, on or before December 15 of the year in which a final determination is made by the last body or tribunal to pass on the matter or within six months of the final determination, whichever is later, request the department to order the officer in charge of the rolls for the intervening years to correct all tax and assessment rolls for those years with respect to the property affected by the final determination. The department may require a hearing and the submission of evidence necessary to determine the correction, if any, that should be made for each intervening year in view of the holding in the final determination. Notwithstanding any time limit in ORS 305.288, 306.115 or 311.205, the department shall order the corrections it deems necessary.
