El 28 de agosto de 2025, W.D. Washington (Estados Unidos) conoció un asunto en el que un abogado se apoyó en una herramienta de IA generativa (no identificada en la decisión) y el expediente registró contenido alucinado.

Qué se alucinó

• Citas falsas de jurisprudencia. Quoted language attributed to Meissner v. Simpson Timber Co. could not be located in that existing Washington case (false quotation).
• Citas falsas de jurisprudencia. Quote attributed to 'Blaise v. Underwood' does not appear in the (similarly named) existing case Balise v. Underwood; quoted language not located (false quotation).
• Citas falsas de jurisprudencia. Quotation attributed to Capitol Hill Methodist Church of Seattle does not appear where cited; pincite omitted and quoted language not found (false quotation).
• Citas falsas de jurisprudencia. In re Sheehan cited with incorrect reporter number and omissions; paragraphs from the opinion appear altered and inserted without ellipses or brackets (misquoted/altered case text).
• Citas falsas de jurisprudencia. Scrivener v. Clark College cited with incorrect page and typographical errors; quoted language placement incorrect (misquote/pincite error).
• Tergiversación de jurisprudencia. Cited Supreme Court and Ninth Circuit authorities (Martel v. Clair and United States v. Emmett) used to support an "is regularly applied" formulation in the Ninth Circuit—both cases inapplicable to the asserted Rule 4(m) proposition and do not contain the quoted phrase (misapplied/misrepresented precedent).
• Citas falsas de jurisprudencia. Beecher v. Wallace quotation reproduced with altered punctuation, capitalization, paragraph breaks, and reporter formatting differing from the original opinion (altered quote/formatting).
• Tergiversación de pruebas o escritos. Counsel represented a document at Dkt. 21-3 as a declaration and quoted language that does not appear there; similar language existed in a different docketed declaration filed by Defendant—Counsel misattributed/ misquoted the record (misrepresentation of exhibits).
• Tergiversación de pruebas o escritos. Investigation report from ABC Messenger Service (Exhibit 9) quoted inaccurately—Counsel added language stating the report 'ensur[ed] that each required document was presented' though the filed report does not include that assurance (misquote of exhibit).
