(1) The reviewing court’s decision under ORS 183.482 or 183.484 may be mandatory, prohibitory, or declaratory in form, and it shall provide whatever relief is appropriate irrespective of the original form of the petition. The court may:
(a) Order agency action required by law, order agency exercise of discretion when required by law, set aside agency action, remand the case for further agency proceedings or decide the rights, privileges, obligations, requirements or procedures at issue between the parties; and
(b) Order such ancillary relief as the court finds necessary to redress the effects of official action wrongfully taken or withheld.
(2) If the court sets aside agency action or remands the case to the agency for further proceedings, it may make such interlocutory order as the court finds necessary to preserve the interests of any party and the public pending further proceedings or agency action.
(3) Unless the court finds a ground for setting aside, modifying, remanding, or ordering agency action or ancillary relief under a specified provision of this section, it shall affirm the agency action.
