(a) In any hearing to refuse to issue, restore, or renew a license or to discipline a licensee or registrant, a copy of the Committee’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 such service, the respondent may present to the Department 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 or rehearing is denied, then upon such denial the Secretary may enter an order in accordance with recommendations of the Committee except as provided in Section 20.7. 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.
     (b) Whenever the Secretary believes that substantial justice has not been done in the disciplinary proceeding, the Secretary may order a rehearing by the same or different hearing officer.
     (c) Upon the suspension or revocation of a registration or license, the registrant or licensee shall be required to surrender to the Department the registration or license issued by the Department, and upon failure or refusal so to do, the Department may seize it.
