Sent. n. 1027/2026
Corte Suprema di Cassazione · Jun 11, 2026
What happened in this matter?
The Corte Suprema di Cassazione declared the appeal inadmissible and ordered the appellant to pay 5,000 EUR to the Cassa delle ammende. The Court explicitly sanctioned the counsel for citing nonexistent, AI-generated case law, noting that such conduct demonstrated a degree of negligence exceeding excusable error and burdened the court's nomophylactic function.
- Why the court cared
- The Court reasoned that the citation of nonexistent jurisprudence generated by AI constitutes a breach of the duty of control and professional negligence. It held that such conduct justifies a higher monetary sanction under art. 616 c.p.p. because it burdens the court's filtering function and violates the minimum reliability required for defensive acts.
- Why it matters now
- This case illustrates the judicial response to the use of AI-generated fake citations in Italian criminal proceedings. It establishes that courts may increase monetary sanctions when counsel fails to verify AI-generated research, viewing such negligence as a breach of the duty of care and an obstruction of judicial efficiency.
Why this matter is tracked
In a criminal execution proceeding, the defence counsel for Aiello Giovanni Battista filed a cassation appeal citing three specific judicial precedents (Cass. pen. n. 18839/2014, n. 53602/2017, and n. 11907/2016) to support arguments regarding procedural validity and the interpretation of an alleged identity error. The Corte Suprema di Cassazione determined that these cited rulings and their attributed principles were nonexistent, characterizing them as 'allucinati' (hallucinated) and likely generated by AI. The Court found the appeal inadmissible due to both the lack of subject identity and the reiterative nature of the claims. Consequently, the Court imposed a monetary sanction of 5,000 EUR in favor of the Cassa delle ammende, citing the counsel's failure to verify sources and the resulting burden on the judicial system.
