(A)   Any person refused a permit to construct or alter a park or a license, or whose license is suspended or revoked, shall have the right to a hearing before the Department. A written notice of a request for such a hearing shall be served upon the Department within 20 days of such refusal of a permit to construct or alter or refusal of a license or suspension or revocation thereof. The Director shall give written notice of such decision, by registered mail, to the park operator or the applicant, as the case may be, within five days of such refusal, suspension or revocation.
   (B)   The hearing shall be conducted by the Director, or a duly qualified employee of the Department designated in writing by the Director as a Hearing Officer.
   (C)   The Director or Hearing Officer may compel by subpoena or subpoena duces tecum the attendance and testimony of witnesses and the production of books and papers, and administer oaths to witnesses. The hearing shall be conducted at such place as designated by the Department, except that hearings concerning the establishment, operation or licensing of a park in a county of 1,000,000 or more inhabitants shall be conducted in such county. The Director shall give written notice of the time and place of hearing, by registered mail, to the park operator or license applicant, as the case may be, at least ten days prior to the hearing.
   (D)   The Director or Hearing Officer shall permit the applicant or licensee to appear in person and to be represented by counsel at the hearing at which time the applicant or licensee shall be afforded an opportunity to present all relevant matter in support of his or her application for license or renewal of license or in resisting the revocation thereof.
   (E)   In the event of the inability of any party, or the Department, to procure the attendance of witnesses to give testimony or produce books and papers, such party or the Department may take the deposition of witnesses in accordance with the law pertaining to the taking of depositions in civil cases in the circuit courts of this state. All testimony taken at a hearing shall be reduced to writing, and all such testimony and other evidence introduced at the hearing shall constitute a part of the record of the hearing.
   (F)   The Director shall make findings of fact in such hearing, and the Director shall render his or her decision within 80 days after the termination of the hearing, unless additional time is required by him or her for a proper disposition of the matter. When the hearing has been conducted by a Hearing Officer, the Director shall review the record before rendering a decision. It shall be the duty of the Director to forward a copy of his or her decision, by registered mail, to the park operator or applicant, as the case may be, within five days of rendering such decision.
   (G)   Technical errors in the proceeding before the Director or Hearing Officer or their failure to observe the technical rules of evidence shall not constitute 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 him or her.
   (H)   All subpoenas issued by the Director or Hearing Officer may be served as provided for in civil actions. The fees of witnesses for attendance and travel shall be the same as the fees for witnesses before the Circuit Court and shall be paid by the party to such proceeding at whose request the subpoena is issued. If such subpoena is issued at the request of the Department, the witness fee shall be paid as an administrative expense.
   (I)   In cases of refusal of a witness to attend or testify, or to produce books or papers, concerning any matter upon which he might be lawfully examined, the Circuit Court of the county wherein the hearing is held, upon application of any party to the proceeding, may compel obedience by proceeding for contempt as in cases of a like refusal to obey a similar order of the Court.
   (J)   The Department shall not be required to certify any record or file any answer or otherwise appear in any proceeding for judicial review unless the party filing the complaint deposits with the Clerk of the Court the sum of $0.95 per page representing costs of such certification. Failure on the part of the plaintiff to make such deposit shall be grounds for dismissal of the action.
