In any hearing involving the refusal to issue, renew, or discipline a license or certificate, 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 Secretary a motion in writing for a rehearing. The motion shall specify the particular grounds for the rehearing. If no motion for rehearing is filed, then upon the expiration of the time specified for filing a motion, or if a motion for rehearing is denied, then upon the denial, then the Secretary may enter an order in accordance with recommendations of the Board except as provided in Section 25.6 of this Act.
