AI Hallucination Cases

The court granted Plaintiff's motion to strike portions of the Opening Brief after Defendant raised concerns that the brief included a non-existent quotation attributed to an existing case, a mischaracterization of an existing case, a citation to a non-existent case, and a miscitation of a case that did not address the asserted issue. The court noted counsel had been sanctioned in a separate case for citation-related deficiencies consistent with AI-generated hallucinations. The stricken portions were removed and the ALJ decision was affirmed.

The court issued an Order to Show Cause, and the plaintiff's Counsel acknowledged responsibility but did not explicitly admit to using AI. The court determined that the counsel violated Rule 11(b)(2) by failing to verify the accuracy of the citations and imposed several sanctions:

• "The pro hac vice status of Counsel shall be revoked and Counsel will be removed from this case;
• Plaintiff’s Opening Brief shall be stricken;
• Counsel will be ordered to promptly serve a copy of this Order on Plaintiff, who will in turn be afforded time to engage new counsel or proceed as a self-represented litigant;
• Counsel will be ordered to write a letter to the three Judges to whom she attributed fictitious cases, [...], notifying them of her use of fake cases with their respective names attached;
• Counsel will be ordered to transmit a copy of this Order to every Judge who presides over any case in which Counsel is attorney of record; and
• The Clerk of Court’s Office will be directed to serve a copy of this Order on the Washington State Bar Association, of which Counsel is a member. If Counsel is a member of any other state’s bar, she shall serve a copy of this Order on that state’s bar office."
