Nikko D’Ambrosio v. Meta Platforms Inc.
7th Cir. CA · May 15, 2026
What happened in this matter?
The Seventh Circuit issued an order to show cause for sanctions against a plaintiff and his attorneys after they filed an appellate brief containing fictitious citations, fabricated quotations, and misrepresentations of law. The court emphasized that counsel is responsible for verifying all filings, regardless of whether generative AI tools were used in the drafting process.
- Why the court cared
- The court reasoned that submitting fictitious quotations and citations constitutes a serious dereliction of an attorney's duty as an officer of the court. It held that misrepresenting holdings or citing nonexistent case law is a false statement to the court, and that this responsibility remains with counsel regardless of whether generative AI was used to generate the content.
- Why it matters now
- This case highlights the judiciary's expectation that counsel must independently verify all legal research and citations. It serves as a warning that firms advertising AI integration remain strictly liable for the accuracy of their filings and the professional conduct of their attorneys.

The court found the appeal frivolous and identified that counsel submitted an appellate brief containing fictitious quotations, citations, and misrepresentations of law, specifically regarding the Doxing Act. The court noted that the firm involved had advertised its use of AI in legal practice, though it emphasized that counsel remains responsible for the accuracy of all filings regardless of the tools used. The court ordered the parties to show cause why sanctions, including attorney fees and fines, should not be imposed.
