A v. B
Florence · Mar 13, 2025
What happened in this matter?
The court declined to impose a financial sanction under Article 96 of the Italian Code of Civil Procedure for the submission of AI-generated fabricated case law. The court accepted the respondent's admission that the errors resulted from unverified AI research conducted by an assistant, and concluded that the threshold for a bad-faith litigation penalty was not met.
- Why the court cared
- The court reasoned that while the submission of fabricated case law was a failure of professional diligence, it did not meet the specific legal requirements for a bad-faith litigation penalty under Article 96 c.p.c. The court noted the respondent's admission that the citations were the result of unverified AI research and accepted the request to strike the references from the record.
- Why it matters now
- Partner liability is real: Italian court stigmatized the lead lawyer for failing to verify ChatGPT output produced by an assistant.
