"Legal commentator Eugene Volokh, a professor at UCLA School of Law who tracks AI in litigation, in February reported on the 14th court case he's found in which AI-hallucinated false citations appeared. It was a Missouri Court of Appeals opinion that assessed the offending appellant $10,000 in damages for a frivolous filing.
Hallucinations aren't the only snag, Volokh says. "It's also with the output mischaracterizing the precedents or omitting key context. So one still has to check that output to make sure it's sound, rather than just including it in one's papers.
Echoing Volokh and other experts, ChatGPT itself seems clear-eyed about its limits. When asked about hallucinations in legal research, it replied in part: "Hallucinations in chatbot answers could potentially pose a problem for lawyers if they relied solely on the information provided by the chatbot without verifying its accuracy."
