225 ILCS 310/14
Upon the motion of either the Department or the Board, or upon the verified complaint in writing of any person setting forth facts which, if proven, would constitute grounds for refusal, suspension, or revocation of registration under this Act, the Board shall investigate the actions of any person, hereinafter called the "registrant", who holds or represents that he holds a certificate of registration. All such motions or complaints shall be brought to the Board.
The Director shall, before suspending, revoking, placing on probationary status, or taking any other disciplinary action as the Director may deem proper with regard to any registration, at least 30 days prior to the date set for the hearing, notify the registrant in writing of any charges made and the time and place for a hearing on the charges before the Board. The Board shall also direct the registrant to file his written answer to the charges with the Board under oath within 20 days after the service on him of such notice, and inform him that if he fails to file such answer, his certificate of registration may be suspended, revoked, placed on probationary status or other disciplinary action may be taken with regard thereto, as the Director may deem proper.
The written notice and any notice in such proceeding may be served by delivery personally to the registrant, by email, or by registered or certified mail to the address specified by the registrant in his last notification to the Director.
The Department, at its expense, shall preserve a record of all proceedings at the formal hearing of any case involving the refusal to issue or renew a registration, or discipline of a registrant. The notice of hearing, complaint, and all other documents in the nature of pleadings and written motions filed in the proceedings, the transcript of testimony, the report of the Board, and the orders of the Department shall be the record of such proceedings.
