The state agency shall keep a record documenting the provision of the notice provided to each party in accordance with Subsection (a).

(c) If an adversely affected party or the party’s attorney of record does not receive the notice required by Subsections (a) and (b) or acquire actual knowledge of a signed decision or order before the 15th day after the date the decision or order is signed, a period specified by or agreed to under § 2001.144(a), 2001.146, 2001.147, or 2001.176(a) relating to a decision or order or motion for rehearing begins, with respect to that party, on the date the party or the party’s attorney of record receives the notice or acquires actual knowledge of the signed decision or order, whichever occurs first. The period may not begin earlier than the 15th day or later than the 45th day after the date the decision or order was signed.
(d) To establish a revised period under Subsection (c), the adversely affected party must prove, on sworn motion and notice, that:

(e) The state agency or a person authorized to act for the agency must grant or deny the sworn motion not later than the date of the agency’s governing board’s next meeting or, for a state agency without a governing board with decision-making authority in contested cases, not later than the 10th day after the date the agency receives the sworn motion.
(f) If the state agency or a person authorized to act for the agency fails to grant or deny the motion at the next meeting or before the 10th day after the date the agency receives the motion, as appropriate, the motion is considered granted.
(g) If a sworn motion filed under Subsection (d) is granted with respect to the adversely affected party filing that motion, all the periods specified by or agreed to under § 2001.144(a), 2001.146, 2001.147, or 2001.176(a) relating to a decision or order, or motion for rehearing, shall begin for the movant on the date specified in the sworn motion that the movant or the movant’s attorney of record first received the notice required by Subsections (a) and (b) or acquired actual knowledge of the signed decision or order. The date specified in the sworn motion shall be considered the date the decision or order was signed for the movant. The timely filing of a sworn motion for rehearing under Subsection (d) extends the period for agency action on any motion for rehearing until the 100th day after the date the decision or order subject to the motion for rehearing is signed.
