If, under a statute, an agency may review the final order of another agency, the review shall be treated as if it was a continuous proceeding before a single agency. For the purposes of this review and the application of section 3 of this chapter concerning the effectiveness of an order, a final order of the first agency shall be treated as a nonfinal order of an administrative law judge, and the second agency shall review the order under section 29 of this chapter. To preserve an issue for judicial review, a party must comply with section 29(d) of this chapter before the second agency. The ultimate authority for the second agency or its designee may conduct proceedings under section 31 of this chapter.
