Lawyer faces penalty for citing AI-generated fake cases in court.

A lawyer, Steven A. Schwartz, may face sanctions for submitting a brief filled with fake judicial opinions and legal citations, all generated by ChatGPT, an artificial intelligence program. Schwartz apologized and said he had made a "deeply regrettable mistake." The incident has sparked a debate about the dangers of relying on AI tools in legal practice. The case involved a man who sued an airline, but the cases cited in his brief were not real. Schwartz and his law firm have asked the judge not to impose sanctions, saying they have already learned their lesson.
