Two U.S. judges in separate federal courts scrapped their rulings last week after lawyers alerted them to filings that contained inaccurate case details or seemingly "hallucinated" quotes that misquoted cited cases — the latest in a string of errors that suggest the growing use of artificial intelligence in legal research and submissions.
In New Jersey, U.S. District Judge Julien Neals withdrew his denial of a motion to dismiss a securities fraud case after lawyers revealed the decision relied on filings with "pervasive and material inaccuracies."
The filing pointed to "numerous instances" of made-up quotes submitted by attorneys, as well as three separate instances when the outcome of lawsuits appeared to have been mistaken, prompting Neals to withdraw his decision.
