- 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.
