In any case involving the refusal to issue or renew or the discipline of a licensee, a copy of the Board’s report shall be served upon the respondent by the Department, either personally or as provided in this Act for the service of the notice of hearing. Within 20 calendar days after the service, the respondent may present to the Department a motion in writing for a rehearing which shall specify the particular grounds for rehearing. If no motion for rehearing is filed, then upon the expiration of the time specified for filing a motion, or if motion for rehearing is denied, then upon denial, the Secretary may enter an order in accordance with recommendations of the Board, except as provided for in Section 120. If the respondent orders a transcript of the record from the reporting service and pays for it within the time for filing a motion for rehearing, the 20 calendar day period within which a motion for rehearing may be filed shall commence upon the delivery of the transcript to the respondent.
