Tribunal Superior de Xustiza de Galicia (Sala do Social, A Coruña)
Auto 61/2026 — Recurso de Suplicación 5472/2025
Sanctioned · 7 July 2026
What was fabricated
Of 32 case citations in the appeal, 24 (75%) were fabricated or wrong — non-existent Supreme Court, Constitutional Court and Court of Justice of the EU rulings, several with invented verbatim quotations, all verified false against the CENDOJ case database. The lawyer used a free generative-AI tool without verification and admitted responsibility. Independently corroborated 5 Aug 2026 by four Spanish outlets, all reporting 24 fabricated references and the EUR1,800 fine; Iberley additionally confirms the auto reference (Auto n. 00061/2026, A Coruna, 7 July 2026, recurso de suplicacion 5472/2025) and the 75% proportion. The raw total of 32 is stated in the auto and follows arithmetically from the two corroborated figures.
What happened as a result
€1,800 fine for breach of procedural good faith (art. 75.4 LJS); referred to the A Coruña Bar (ICACOR) for disciplinary action. The court set the fine by reference to the annual cost of a verified legal-AI research subscription (naming tools such as Sof-IA/Tirant, GenIA-L/Lefebvre, K+/Aranzadi and Harvey AI — €1,500–3,000/yr), reasoning that such a paid tool, or a free CENDOJ check, would have prevented the hallucinations. Follows the TSJ Canarias precedent of 10 Feb 2026.
