To enforce against a violation of the Act or any rule adopted under this Act by any local government or political subdivision as described in this Act, any interested party may file suit in circuit court in the county where the alleged violation occurred or where any person who is a party to the action resides. Actions may be brought by one or more persons for and on behalf of themselves and other persons similarly situated. If the interested party prevails in its enforcement action, it will be entitled to recover damages of 3 times its attorney's fees and costs, and, in addition, the court or other adjudicating body, at its discretion, may assess punitive damages for any wanton or flagrant violation of the law.
