The Director, after notice and opportunity for hearing to the applicant, license holder, or registrant, may deny, suspend, or revoke a license or registration in any case in which he or she finds that there has been a substantial failure to comply with the provisions of this Act or the standards, rules, and regulations established under this Act.
Notice shall be provided by certified mail or by personal service setting forth the particular reasons for the proposed action and fixing a date, not less than 20 days from the date of the mailing or service, within which time the applicant or license holder must request in writing a hearing. Failure to serve upon the Department a request for hearing in writing within the time provided in the notice shall constitute a waiver of the person's right to an administrative hearing.
The hearing shall be conducted by the Director or by an individual designated in writing by the Director as a hearing officer to conduct the hearing. The Director or hearing officer shall give written notice of the time and place of the hearing, by certified mail or personal service, to the applicant, license holder, or registrant at least 10 days prior to the hearing. On the basis of the hearing, or upon default of the applicant, license holder, or registrant, the Director shall make a determination specifying his or her findings and conclusions. A copy of the determination shall be sent by certified mail or served personally upon the applicant, license holder, or registrant. The decision of the Director shall be final on issues of fact and final in all respects unless judicial review is sought as provided in this Act.
The procedure governing hearings authorized by this Section shall be in accordance with rules promulgated by the Department. A full and complete record shall be kept of all proceedings, including the notice of hearing, complaint, and all other documents in the nature of pleadings, written motions filed in the proceedings, and the report and orders of the Director and hearing officer.
The Department at its expense shall provide a court reporter to take testimony. Technical error in the proceedings before the Department or hearing officer or their failure to observe the technical rules of evidence shall not be grounds for the reversal of any administrative decision unless it appears to the Court that such error or failure materially affects the rights of any party and results in substantial injustice to them.
The Department or hearing officer, or any parties in an investigation or hearing before the Department, may cause the depositions of witnesses within the State to be taken in the manner prescribed by law for depositions in civil actions in courts of this State, and compel the attendance of witnesses and the production of books, papers, records, or memoranda.
The Department shall not be required to certify any record to the Court or file any answer in Court or otherwise appear in any Court in a judicial review proceeding, unless there is filed in the Court with the complaint a receipt from the Department acknowledging payment of the costs of furnishing and certifying the record. Such cost shall be paid by the party requesting a copy of the record. Failure on the part of the person requesting a copy of the record to pay the cost shall be grounds for dismissal of the action.
