A lawyer in New Mexico was fined $5,000 and held in contempt of court for submitting a legal brief that contained AI-hallucinated witnesses (false information generated by an AI model that seemed plausible but was completely made up) and fake testimony in a murder case appeal. The court ruled that he failed to verify the facts and legal citations in his AI-generated document before submitting it to the court.
