R.G. 48964/2025 (opposizione all'esecuzione)
Trib. Milano · Jun 5, 2026
What happened in this matter?
The court identified fabricated case law citations in the defendant's brief, attributing them to unverified AI usage. As a result, the court penalized the defendant by limiting the recoverable litigation costs to only the study and introductory phases, excluding other phases of the proceeding.
- Why the court cared
- The court reasoned that the inclusion of non-existent or misattributed jurisprudential maxims in the defendant's brief constituted negligence and a failure to verify AI-generated content. Although the court noted this conduct could be considered a violation of art. 88 c.p.c. (duty of loyalty and integrity), it opted to limit the recovery of litigation costs to the study and introductory phases rather than imposing further disciplinary measures, as the underlying defense was otherwise well-founded.
- Why it matters now
- This case illustrates a judicial response to AI-generated hallucinations in legal filings. By limiting recoverable costs, the court established a direct financial consequence for failing to verify AI-assisted research, emphasizing the professional duty of counsel to supervise automated tools.
Why this matter is tracked
In an opposition to execution proceeding, the Tribunale di Milano rejected the debtor's claims regarding the legitimacy of a securitized credit and the representative capacity of the servicer. During the assessment of litigation costs, the court identified that the defendant's brief contained three jurisprudential 'massime' attributed to specific Court of Cassation decisions (Cass. 21432/2021, 7024/2017, and 24058/2004) that did not correspond to the actual content of those rulings. The court attributed these errors to the unverified use of generative AI, characterizing the conduct as negligent. Consequently, while the court awarded litigation costs to the defendant, it limited the recovery to only the study and introductory phases of the proceeding.
