Indiana Code Title 4. State Offices and Administration § 4-21.5-3-31

Sec. 31. (a) An ultimate authority has jurisdiction to modify a final order under this section before the earlier of the following:

(b) A party may petition the ultimate authority for an agency for a stay of effectiveness of a final order.  The ultimate authority or its designee may, before or after the order becomes effective, stay the final order in whole or in part.

(c) A party may petition the ultimate authority for an agency for a rehearing of a final order.  The ultimate authority or its designee may grant a petition for rehearing only if the petitioning party demonstrates that:

The rehearing may be limited to the issues directly affected by the newly discovered evidence.  If the rehearing is conducted by a person other than the ultimate authority, section 29 of this chapter applies to review of the order resulting from the rehearing.

(d) Errors in a final order or other part of the record of a proceeding may be corrected by an ultimate authority or its designee on the motion of any party or on the motion of the ultimate authority or its designee.

(e) An action of a petitioning party or an agency under this section, including a motion to correct error, tolls the period in which a party may object to a second agency under section 30 of this chapter and tolls the period in which a party may petition for judicial review under IC 4-21.5-5.  A new period begins to run on the date a motion to correct error is denied or a new order is issued.  A motion to correct error or motion for a rehearing is deemed denied thirty (30) days after it was filed if there is no ruling on the motion or no hearing is set on the motion.
