A federal judge in Mississippi has punished all four lawyers on opposing sides in a civil trial and canceled the proceedings after some of them, relying on artificial intelligence, cited fake legal cases in court filings.

In an order filed on Monday, Sharion Aycock, a senior U.S. District Court judge, wrote that the four lawyers had violated Rule 11 of the Federal Rules of Civil Procedure when they certified that the information in their filings was factual.

I think one concerning thing is that this is the easiest thing to check. I mean, at some point, I assume that someone is going to rig something up to LexisNexis to actually validate the existence of cited cases, because that’s pretty simple and mechanical. Heck, even those lawyers, even if they don’t have any tech people at their fingertips, could have had a paralegal check citations or something.

My bigger concern is that if lawyers are willing to put stuff like this out, they’re presumably also willing to put out information that hasn’t been checked where the errors are subtler and it’s harder to find erroneous material. In the case of citing nonexistent cases, it’s really easy to say “the lawyer clearly didn’t even look at this”, because it’s hard to make that kind of error if you have read over it. But…there’s potential for subtler errors, where it’s harder to tell whether the lawyer just made a basic error, and thus harder to impose punishments for it.
