Indiana Code Title 4. State Offices and Administration § 4-21.5-3-32

Sec. 32. (a) Each agency shall make all written final orders available for public inspection and copying under IC 5-14-3.  The agency shall index final orders that are issued after June 30, 1987, by name and subject.  An agency shall index an order issued before July 1, 1987, if a person submits a written request to the agency that the order be indexed.  An agency shall delete from these orders identifying details to the extent required by IC 5-14-3 or other law.  In each case, the justification for the deletion must be explained in writing and attached to the order.

(b) An agency may not rely on a written final order as precedent to the detriment of any person until the order has been made available for public inspection and indexed in the manner described in subsection (a).  However, this subsection does not apply to any person who has actual timely knowledge of the order.  The burden of proving that knowledge is on the agency.
