El 18 de mayo de 2026, W.D. Louisiana (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. Counsel cited Tompkins v. Cyr for a rule about prior settlements/verdicts being irrelevant; the court could not find that language or the referenced topic in Tompkins.
• Citas falsas de jurisprudencia. Counsel relied on Collins v. Wayne Corp. to support the same proposition about prior settlements; the court found Collins unrelated to that issue.
• Citas falsas de jurisprudencia. Brief quoted 'the policy behind Rule 408 is to encourage settlements' and attributed it to Bankcard America; the court found Bankcard America uses 'purpose' not the quoted wording.
• Citas falsas de jurisprudencia. Counsel attributed the phrase 'must have acted in "bad faith"' to King v. Illinois Central R.R.; the court found the phrase is not present in the cited opinion.
• Citas falsas de jurisprudencia. Counsel quoted language about surgery and spoliation attributed to Gilliam v. Uni Holdings; the court found the quoted sentences do not appear at the cited pincite and the correct pages differ.
• Citas falsas de jurisprudencia. Brief quoted 'did not have a duty to delay his surgery' and cited Menges v. Cliffs Drilling Co.; the court found that quoted phrase does not appear in Menges at the cited location.
• Citas falsas de jurisprudencia. Brief quoted a sentence about the 'tortfeasor tak[ing] his victim as he finds him' and cited Lasha v. Olin Corp.; the court found the opinion uses 'defendant' (not 'tortfeasor') and the pincite was incorrect.
