ChatGPT's Fake Case Citations Lead to Lawyer Fines

Lawyers from the firm Levidow, Levidow, & Oberman were fined $5,000 and had their lawsuit dismissed after using ChatGPT to research court filings that cited six fake cases invented by the AI tool. The lawyers "abandoned their responsibilities" and "advocated for the fake cases and legal arguments" even after being informed that their citations were non-existent. The judge described the legal analysis in one of the fake cases as "gibberish." The lawyers are required to send letters to six real judges who were "falsely identified as the author of the fake" opinions cited in their legal filings.
