Why this matter warrants attention
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.
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.
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.
