Illinois Administrative Review Summons is a court document issued by the Illinois Administrative Review Law (ARL) that requires a respondent to appear in court and defend against a complaint. It is issued to a respondent who has been accused of violating a law or regulation administered by a state agency. The summons is served to the respondent either through personal service or by registered mail. The summons will contain the details of the complaint, the date for the hearing, and any other relevant information. There are two types of Illinois Administrative Review Summons: a Notice of Hearing Summons, which is issued when the respondent has an opportunity to present evidence, and a Summary Judgment Summons, which is issued when the respondent does not have an opportunity to present evidence. Both types of summons require the respondent to appear before the administrative law judge and respond to the complaint.
