California Judge Fines Law Firm $31,000 Over AI-Generated Fake Citations

Los Angeles, CA — A federal judge has sanctioned a prominent law firm $31,000 after discovering it submitted a legal brief riddled with fictitious citations generated by artificial intelligence.

The controversy began several weeks ago when U.S. Magistrate Judge Michael Wilner, based in California, noticed irregularities in a filing submitted by attorneys from the high-profile firm Ellis George. Curious about the arguments presented, Judge Wilner attempted to verify the cited sources—only to find that the referenced articles did not exist.

In response to the judge’s concerns, the law firm filed a second brief. Instead of resolving the issue, it introduced even more inaccuracies, prompting Judge Wilner to order sworn declarations from the attorneys involved.

According to a court filing dated May 6, one of the attorneys admitted to using generative AI tools, including Google Gemini and other law-focused AI platforms, to help draft the original submission. These tools produced fabricated legal citations that were passed off as legitimate.

Calling the incident a “real-life cautionary tale,” Judge Wilner imposed a $31,000 penalty on the firm, citing a failure to meet the basic duty of factual accuracy in court proceedings.
