A U.S. federal appeals court has fined two attorneys for submitting false case citations that misrepresent the law. The court found more than two dozen fake citations and misrepresentations of fact in the appeal, which involved an incident at a fireworks show hosted by Athens, Tennessee. The attorneys must pay $15,000 each to the appeals court as a punitive sanction. The decision comes as more courts struggle with errors attributed to generative artificial intelligence platforms, which sometimes fabricate information. Lawyers are not prohibited from using AI tools but are required to safeguard the accuracy of their submissions.
