- Florida politician and attorney Anthony F. Sabatini accused of 'blatant and repeated misconduct' for using AI to generate fabricated legal citations in briefs.
- The court specifically faulted Sabatini for multiple instances of AI hallucinations in legal filings representing plaintiffs.
- A study reveals leading AI legal research tools hallucinate 17% to 33% of the time, raising concerns about reliance on AI in legal practice.
- Similar cases, such as Mata v. Avianca, led to sanctions for submitting AI-generated fictitious case citations, underscoring broader risks.
Florida lawyer and politician Anthony F. Sabatini has faced significant judicial criticism for his use of AI-generated legal briefs containing fabricated citations. The court labeled Sabatini's conduct as "blatant and repeated misconduct," pointing to repeated AI hallucinations in briefs filed on behalf of plaintiffs.[Reason]
This case is not isolated. In the 2026 case Mata v. Avianca, Inc., attorneys were sanctioned for submitting briefs with fictitious citations generated by AI tools, illustrating the tangible legal risks of unverified AI content in pleadings.[ABA Litigation Newsletter]
Research indicates leading AI legal research tools hallucinate information 17% to 33% of the time, meaning they often fabricate plausible but false content. This poses clear ethical and professional hazards for attorneys relying on these tools without rigorous fact-checking.[arXiv]
The Sabatini matter highlights the urgent need for lawyers to maintain diligence in verifying AI-generated results. As courts grow increasingly intolerant of AI-induced errors, attorneys must balance AI's efficiency with the profession’s duty to uphold factual accuracy and legal ethics.
By the numbers:
- 17%-33% — Hallucination rate of leading AI legal research tools
