(a) Except in connection with interim appeals of orders or questions certified to an agency by an administrative law judge, as permitted by law, a state agency that has referred a matter to the office in which the office will conduct a hearing may not take any adjudicative action relating to the matter until the office has issued its proposal for decision or otherwise concluded its involvement in the matter. The state agency may exercise its advocacy rights in the matter before the office in the same manner as any other party.
(b) If the office issues a proposal for decision in a matter referred to the office by a state agency, the referring agency shall send to the office an electronic copy of the agency’s final decision or order in the matter.
