Lawyers blame ChatGPT for tricking them into citing bogus case law

A judge is deciding whether to sanction two lawyers who blamed ChatGPT for tricking them into including fictitious legal research in a court filing. The lawyers apologized at a hearing Thursday in Manhattan federal court for their roles in written submissions that seemed to leave Judge P. Kevin Castel both baffled and disturbed at what happened. The filing was in a lawsuit against an airline and included references to past court cases that Steven A. Schwartz thought were real. They were actually invented by the artificial intelligence-powered chatbot. Castel repeatedly expressed his dismay as he questioned Schwartz about his decision to use ChatGPT. He did not immediately rule.
