Judges in New Jersey and Mississippi Admit AI Tools Produced Erroneous Federal Court Filings

June 30, 2025

Two U.S. federal judges, Julien Neals (D.N.J.) and Henry Wingate (S.D. Miss.), admitted that staff in their chambers used AI tools, ChatGPT and Perplexity, to draft rulings containing purportedly fabricated quotes, cases, and parties. The erroneous filings were reportedly docketed before review, leading to Senate and judicial inquiries, ultimately resulting in the retracting of both rulings. This incident underscores the importance of trustworthy AI practices and responsible AI governance within our legal system.
