Tribunale di Mantova, Sentenza n. 165/2026
Trib. Mantova · Mar 24, 2026
What happened in this matter?
The court sanctioned the plaintiff for gross negligence after finding that multiple legal precedents cited in the plaintiff's brief were misattributed and did not support the arguments presented. The court inferred the use of AI in the drafting process due to the nature of the errors and ordered a monetary penalty under Article 96, paragraph 3 of the Italian Code of Civil Procedure.
- Why the court cared
- The court reasoned that the plaintiff's reliance on multiple non-existent or misattributed precedents constituted gross negligence. It specifically noted that the plaintiff failed to verify the content of the cited rulings despite the defendant having previously challenged the accuracy of these citations. The court concluded that the systematic nature of the errors, which were central to the plaintiff's argument, warranted a sanction under art. 96/3 c.p.c. to compensate the defendant for the burden of addressing the erroneous submissions.
- Why it matters now
- This case illustrates the judicial response to AI-assisted legal drafting where counsel fails to verify the accuracy of generated citations. It highlights that courts may infer AI usage from patterns of misattribution and impose monetary sanctions for gross negligence under procedural rules.
Why this matter is tracked
The Tribunale di Mantova sanctioned a plaintiff for submitting a brief containing multiple misattributed legal precedents. The court verified the cited Cassazione rulings against the official database and found that none of the cited decisions contained the propositions attributed to them by the plaintiff. The court characterized these errors as a failure to verify the accuracy of the research, noting that the pattern of misattribution suggested the use of artificial intelligence in drafting the brief. Consequently, the court applied Article 96, paragraph 3 of the Italian Code of Civil Procedure, finding the plaintiff acted with gross negligence. The court ordered the plaintiff to pay a monetary penalty and adverse costs to the defendant.
