A declaratory order has the same status and binding effect as a final order in a contested case proceeding. It is binding on the office, the petitioner and any intervenors and is applicable only in circumstances where the relevant facts and the law involved are indistinguishable from those on which the order was based. As to all other persons, a declaratory order serves only as precedent and is not binding on the office. The issuance of a declaratory order constitutes final office action on the petition.
