Law360 reports 7th Circ. Fines Deported Migrant's Atty For ChatGPT Misuse -- The Seventh Circuit has rejected a Mexican citizen's petition challenging an immigration court's removal order on the merits, while sanctioning his attorney $5,000 for filing two legal briefs "riddled with" fabricated quotes and case citations hallucinated by ChatGPT. Opinion here.
"Roughly half of the cases cited in the brief either do not exist or were falsely labeled as Seventh Circuit cases. Moreover, nearly every quotation in the brief could not be traced to a real opinion — hallmarks of AI hallucinations."
