N.D. Illinois · Dec 10, 2025

Direct answer

What happened in this matter?

The court issued a warning to the defendants after identifying that they submitted filings containing inaccurate legal citations, which the court attributed to the use of generative AI. The court cautioned that continued submission of false information or erroneous citations may result in future sanctions.

Why the court cared
Misrepresented: Case Law | Court found 'Rowe v. State of Lombard' exists but the reporter volume and first page were represented inaccurately in the Swanlunds' filing; citation details were misreported. || Misrepresented: Case Law | Court found cases called 'O'Sullivan v. City of Chicago' exist but the Swanlunds misreported reporter volume, first page, date, and court; real O'Sullivan cases do not appear to support the cited proposition.
Why it matters now
Even 'real' cases with wrong reporter cites now draw AI-misuse warnings — verify reporter, page, and holding for every citation.

Why this matter is tracked

In a memorandum opinion and order denying a motion for judgment on the pleadings, the court identified that the defendants, the Swanlunds, submitted filings containing erroneous legal citations. Specifically, the court found that while cases titled 'Rowe v. State of Lombard' and 'O'Sullivan v. City of Chicago' exist, the defendants misreported the reporter volumes, page numbers, dates, and courts for these authorities. Furthermore, the court noted that the cited O'Sullivan cases did not support the propositions for which they were offered. Attributing these errors to the use of generative artificial intelligence, the court issued a formal warning to the defendants, cautioning that future submissions of false information or erroneous citations may result in sanctions.

Operational lesson

Even 'real' cases with wrong reporter cites now draw AI-misuse warnings — verify reporter, page, and holding for every citation.
