Spain AI-generated legal citation sanctions

Overview

In late July 2026, Spain’s Supreme Court flagged the first known instance of an AI‑generated “hallucination” in a legal brief, where a lawyer cited non‑existent jurisprudence. The court ordered the attorney to verify every citation within three days, highlighting the need for rigorous review of AI‑produced text.

A week later, the Penal Chamber of the Canary Islands’ Superior Court imposed an €840 fine on a lawyer whose appeal contained dozens of fabricated Supreme Court and Constitutional Court citations generated by AI. The ruling emphasized that lawyers remain fully responsible for verifying sources, and it referenced an earlier similar fine in February, underscoring a growing judicial crackdown on AI‑driven misinformation in legal filings.

By late August, the High Court of Justice of the Canary Islands issued another sanction, fining a lawyer €450 for including 48 non-existent Supreme Court rulings and a fictitious report from the General Council of the Judiciary. The lawyer attributed the errors to ChatGPT but failed to verify the data against the official Cendoj database. The court characterized the incident as a result of “blind trust in generative AI” rather than malicious intent. This fine, calculated to be roughly half the annual cost of a specialized legal AI subscription, serves as a pedagogical warning that AI tools do not replace the professional responsibility to verify primary legal sources.
