Lawyer faces sanctions for using ChatGPT to create fake case citations

A lawyer in New York was caught using the ChatGPT chatbot to cite legal cases that the chatbot made up during deliberations on a lawsuit. The court was surprised to find that the cited cases did not exist or were "bogus." The lawyer's colleague cited ChatGPT in an affidavit to the court, stating that he was "unaware of the possibility that its content could be false" and that he had no intent to deceive the court. The lawyer expressed regret and promised to never use AI to supplement legal research without absolute verification of its authenticity.
