Alicante court asks bar to consider discipline over AI-style fabricated quotation in brief

AI Model: Unspecified generative AI tool

I. Executive Summary

Spanish media reported that the Provincial Court of Alicante (civil section) proposed that the local bar consider disciplinary action after finding a lawyer’s appeal brief attributed a supposed verbatim quotation to a Supreme Court decision that did not appear in the actual ruling. The court stated the problem was consistent with “hallucinations” from artificial intelligence or, alternatively, a willful attempt to mislead. The incident arose in an insolvency-related proceeding and resulted in the court forwarding the matter for potential professional discipline.

II. Key Facts

  • A lawyer’s appellate brief included purported verbatim text attributed to a recent Spanish Supreme Court civil decision.
  • The Provincial Court compared the quoted passage against the underlying decision and found the quotation was not present.
  • The court stated the issue was consistent with AI “hallucinations” or a willful attempt to deceive.
  • The court decided to forward the decision to the Alicante Bar for possible disciplinary action.

III. Regulatory & Ethical Implications

Strengthens the emerging European enforcement pattern: “AI-assisted” does not mitigate a lawyer’s duty of candor and verification. The referral mechanism (court → bar) signals a pathway from procedural misconduct findings to professional discipline, incentivizing law firms to formalize AI governance, citation checking, and audit trails for drafting/research.
