In any case involving the refusal to issue or renew a license 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 days after 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 the motion, or if a motion for rehearing is denied, upon the denial, the Secretary may enter an order in accordance with recommendations of the Board, except as provided in Section 115 of this Act. If the respondent orders from the reporting service and pays for a transcript of the record within the time for filing a motion for rehearing, the 20-day period within which the motion may be filed shall commence upon the delivery of the transcript to the respondent.
