225 ILCS 90/23

In any case involving the refusal to issue or renew a license or the taking of disciplinary action against a license, a copy of the Board's report shall be served upon the respondent by the Department, either personally or by mail to the respondent's address of record or email address of record. Within 20 days after such service, the respondent may present to the Secretary a motion in writing for a rehearing, which motion shall specify the particular grounds therefor. If no motion for rehearing is filed, then upon the expiration of the time specified for filing such a motion, or if a motion for rehearing is denied, then upon such denial the Secretary may enter an order in accordance with recommendations of the Board except as provided in Section 22 of this Act. If the respondent shall order from the reporting service, and pay for a transcript of the record within the time for filing a motion for rehearing, the 20-day period within which such a motion may be filed shall commence upon the delivery of the transcript to the respondent.
