All final administrative decisions of the Director or his representative are subject to judicial review under the Administrative Review Law. The term “administrative decision” is defined as in Section 3-101 of the Code of Civil Procedure. The filing for judicial review shall stay the order of the Director or his representative pending disposition of the order on judicial review. The court, upon its own initiative or upon motion by the Director, may in its discretion, when it deems it necessary to protect the interests involved, require the posting of additional bond in an amount it deems advisable, as a prerequisite to judicial review.
