What Happened
In Whiting v. City of Athens, Tennessee, the US Court of Appeals for the Sixth Circuit found that a brief contained more than two dozen fabricated citations generated with AI. On 13 March 2026 the court awarded attorney fees, doubled costs, imposed $15,000 in punitive damages on each responsible attorney, and referred them for disciplinary proceedings. The same 2026 review catalogues an escalating pattern: a Fifth Circuit sanction of $2,500 in Fletcher v. Experian on 18 February 2026 involving 16 fabricated quotations and an attorney who misled the court about generative AI use, plus public admonishments in Fourth Circuit and Eastern District of North Carolina matters.

Sports Illustrated published product reviews under fake AI-generated authors with AI headshots
Futurism reported in November 2023 that Sports Illustrated published product-review content under fabricated author personas — for example 'Drew Ortiz,' whose headshot was bought from an AI-portrait site and who had no real existence — supplied by third-party vendor AdVon Commerce. After inquiries, the fake authors vanished from the site. Publisher The Arena Group denied the articles themselves were AI-written but acknowledged pseudonyms; the episode damaged SI's credibility.
New York City's official 'MyCity' business chatbot told entrepreneurs they could break the law
NYC's MyCity chatbot, launched October 2023 to help business owners, was found by The Markup (March 2024) to give dangerously inaccurate legal guidance — telling users that landlords could refuse Section 8 voucher holders, that employers could take a cut of workers' tips, and that there were no limits on residential rent, all illegal under NYC/NY law. The city initially kept the bot online with a disclaimer; it was ultimately taken down.
Mississippi federal judge removed all four lawyers from a case after both sides filed AI-hallucinated citations
In the contract dispute between Tom Withers III and the City of Aberdeen, both legal teams filed briefs containing fabricated legal citations produced by generative AI. On 8 June 2026 US District Judge Sharion Aycock of the Northern District of Mississippi issued a sanction order finding Rule 11 violations and removed all four attorneys from the case: Kathleen Wilson, Shauncey Hunter Ridgeway, Mark McClinton and Kathryn Young Williams. Two of them, Ridgeway and McClinton, were barred from appearing before Northern District of Mississippi courts for two years. Judge Aycock wrote that their practice of blindly relying on technology resulted in the hallucinatory citations in their filings, and at a January 2026 hearing attorney Kathleen Wilson testified she did not know AI could hallucinate sources.
