Federal Judge Removes Attorneys From Both Sides After AI-Generated Citations Found in Filings

A federal judge removed attorneys from both sides of a lawsuit after AI-generated legal citations appeared in court filings. The filings contained fictitious case references and false quotations generated by large language models. Judges have previously issued milder sanctions in similar cases, but the simultaneous occurrence on both sides of one matter prompted stronger action.

Attorneys have submitted court documents containing AI-generated citations that do not correspond to actual cases or quotations. The practice occurs when generative AI tools produce fabricated references that lawyers include without verification. Courts have treated earlier incidents with warnings or modest financial penalties.

The current case marks an instance where both parties relied on the same type of erroneous content.

Three patterns have been identified: court detection of both sides' errors, one side reporting the other's errors while unaware of its own, and mutual reporting by both sides. In the reported matter, the court identified the issue independently. The adversarial process assumes each side will review opposing filings for accuracy.

Failure by both sides to detect the fabricated citations contributed to the decision to remove the attorneys.
