Which of the following is true about the Appellate Courts in Illinois?

The Appellate Courts in Illinois primarily handle appeals from Circuit Courts, making this statement correct. In the legal system, the Appellate Courts do not conduct trials or hear new evidence; instead, they review the decisions made by lower courts, such as the Circuit Courts, to determine if there were legal errors that may have affected the outcome of a case.

This appellate review process is an essential function as it ensures that individuals have a means to challenge and seek redress against potential mistakes or misinterpretations of the law that may have occurred at the trial level.

Other options present concepts that do not accurately reflect the structure and function of the Appellate Courts in Illinois. For instance, conducting jury trials is not within their role; they review briefs and documents, often based on the record from the trial court. Furthermore, the Appellate Courts are not the lowest level of courts; that designation belongs to the Circuit Courts. Finally, their jurisdiction is much broader than just family law; they deal with a wide range of legal issues, including criminal, civil, and administrative matters.
