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