El 17 de noviembre de 2025, E.D. Missouri (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

• Fabricación de jurisprudencia. Liberty Mutual cited a non-existent case 'Chaudhri v. State Auto Prop. & Cas. Ins. Co., 2022 WL 4596697 (E.D. Mo. Sept. 30, 2022)'; the Court found the citation does not exist and the intended Chaudhri decision did not support the asserted proposition.
• Fabricación de jurisprudencia. Liberty Mutual cited a non-existent case 'Goodman v. Liberty Mut. Fire Ins. Co., 2022 WL 4534416 (E.D. Mo. Sept. 28, 2022)' to support its argument; the Court found the citation does not exist and the intended Goodman case did not support the asserted proposition.
• Tergiversación de jurisprudencia. Liberty Mutual mischaracterized and partially misquoted Dhyne v. State Farm, asserting it supported cooperation clauses and EUO requirements when the cited decision does not address those issues as claimed.
• Tergiversación de doctrina. Liberty Mutual cited sections of 30 Mo. Prac., Insurance Law & Practice (§§ 4:2, 4:8, 4:9) as supporting that cooperation clauses/EUO requirements are longstanding and give rise to a presumption of prejudice; the Court found those sections do not contain the claimed statements and were mischaracterized.
