110 ILCS 1005/10
The Board shall make a written report of its findings and recommendations. A copy of the report shall be served upon the accused person, either personally or by registered mail as provided in this Act for the service of the citation. Within 20 days after such service, the accused person may present to the Board his motion in writing for a rehearing, which motion shall specify the particular grounds therefor. If the accused person orders and pays for a transcript of the record as provided in this Section, the time elapsing thereafter and before such transcript is ready for delivery to him shall not be counted as part of such 20 days.
Whenever the Board is satisfied that substantial justice has not been done, it may order a rehearing. Upon the revocation of the certificate, the certificate shall be surrendered to the Board, and upon the holder's failure or refusal so to do, the Board may seize it.
