Kid International, LLC v. City National Bank of Florida
In Florida's Fourth District Court of Appeal, counsel for Kid International filed an AI-assisted brief citing a hallucinated case seven times and fabricated quotations from real authorities.

Tapscott v. Fariss
In the Court of Appeals of Iowa, a self-represented appellant's final brief in a protective-order appeal contained multiple hallucinated case citations.

Washington v. Justice
In Florida's Second District Court of Appeal, self-represented appellants filed a brief citing eleven cases the court could not find and likely generated by AI.

2026-10-02Filing struck
Shannon v. Shannon, 322 Neb. 451 (2026)
In Nebraska, the state Supreme Court struck a self-represented divorce litigant's appellate brief for fictitious citations produced by his admitted AI use. Extending Prososki v. Regan to unrepresented parties, it held such briefs sanctionable, reviewed only for plain error, affirmed, and warned that future appeals may be dismissed outright.
2026-09-24Regulatory referral
Cervantes v. Bianco
In California, the state Supreme Court disapproved the improper use of AI tools in the Riverside County sheriff's briefing in a ballot-seizure writ case, after the law firm misquoted Common Cause v. Board of Supervisors to challenge standing. The firm apologised and withdrew the argument; the court referred the matter to the State Bar.

R. M. v. Mohr, 353 Or App 182 (2026), A188092
In Oregon, the Court of Appeals ordered a self-represented restraining-order appellant to pay $250 after his brief cited three fabricated cases he admitted came from AI. The court had threatened $1,500, at $500 per fake authority, but reduced the amount for his apology and limited means, then affirmed on the merits.
2026-09-22Warning
Eric Posey v. Summer Bushnell, Docket No. 52072 (Idaho 2026)
In Idaho, the state supreme court affirmed Eric Posey's defamation judgment after finding Summer Bushnell's pro se appellate briefing relied on fabricated or inaccurate quotations and possibly unverified AI output. The court declined a monetary sanction but warned that AI use does not excuse inaccurate briefing.
2026-09-16Pending
Lisandrillo v. Palozzi
In Florida's Fourth District Court of Appeal, petitioner's counsel Jaclyn R. Soroka filed an emergency writ petition and related filings the court suspected contained AI-generated components, including convoluted false arguments but no fake citations. The court denied relief and ordered counsel to show cause within ten days why sanctions, including Florida Bar referral, should not issue.
