El 29 de septiembre de 2025, Upper Tribunal (Reino Unido) conoció un asunto en el que un abogado se apoyó en la herramienta de IA Microsoft Copilot y el expediente registró contenido alucinado.

Qué se alucinó

• Fabricación de jurisprudencia. Grounds cited a Honduras country guidance decision that does not exist; judge found the MN Honduras CG [2016] authority fabricated.
• Fabricación de jurisprudencia. Grounds cited an Eritrea appellate decision that does not exist (YH (Eritrea) [2008] UKAIT 00070); judge accepted counsel's concession that case was fictional.
• Tergiversación de jurisprudencia. HK v SSHD [2006] EWCA Civ 1037 was cited as supporting 'trauma-informed principles' but judge found the case does not discuss that; citation misapplied.
• Tergiversación de jurisprudencia. MA (Somalia) v SSHD was referenced but counsel produced the Supreme Court decision instead of the Court of Appeal authority relied upon; judge found no support for the asserted proposition.
• Tergiversación de jurisprudencia. A citation labelled 'SC (Protection) [2020] UKSC 9' did not match the case title; judge found a citation mismatch and irrelevant authority was cited for internal relocation principles.
• Tergiversación de jurisprudencia. R (YH) v SSHD [2010] EWCA Civ 116 was deployed in grounds but judge noted ChatGPT has recently wrongly deployed that case in similar submissions; authority was misused.
