Appeal of Pension Board Decision Dismissed for Violation of Court Rules in Use of AI

An Illinois Appellate Court recently dismissed the appeal by a former police officer of a pension board’s denial of pension benefits because he violated Illinois Supreme Court Rules when he filed an appellate brief almost wholly created with the aid of artificial intelligence (AI). Pletcher v. Village of Libertyville Police Pension Board.

The plaintiff was hired as a police officer in 2003, and filed an application for a non-duty disability pension in 2020. He subsequently withdrew his application, and returned to full duty. In 2022, he was placed on a performance improvement plan for certain violations of department orders and policies. Shortly thereafter, he filed a second application for a non-duty disability pension. The pension board held a hearing on the application and ultimately denied his application, finding that the officer’s condition could have been remedied with medication, which the pension board found the officer refused to regularly to take.

The officer filed a complaint for administrative review with the trial court to appeal the pension board’s decision, along with a brief supporting his complaint. In his brief, he cited to several cases that did not exist. At the hearing, the officer also attempted to introduce new evidence and exhibits that were not part of the original hearing. The pension board brought the nonexistent cases to the attention of the trial court and objected to the introduction of new evidence. At the conclusion of the hearing, the trial court upheld the pension board’s denial of his pension application.

The officer then appealed to the Appellate Court. After he filed his brief with the Appellate Court, the pension board filed a response and a motion for sanctions alleging that the officer violated Illinois Supreme Court Rules for fictitious citations to the administrative record, citations to nonexistent cases, and fictitious holdings from actual cases. The Appellate Court noted that all parties in litigation (even pro se litigants) are obligated to comply with court rules and procedures. The Court also noted that the officer had cited five cases in his appellate brief that did not exist, and that the some of the actual cases cited in his brief did not stand for the propositions stated in his brief. The Court stated that the officer’s status as a “pro se” party does not excuse his careless reliance on AI, and that he was aware of the risks of using AI-generated research when this same issue was raised at the trial court and yet he still chose to use AI in this manner in his appellate brief. After holding oral argument on the motion to dismiss the appeal, the Appellate Court granted the pension board’s motion and the officer’s appeal was dismissed.
