The 11th U.S. Circuit Court of Appeals named attorney Anthony Sabatini in a published opinion and referred him to the court's Committee on Lawyer Qualifications and Conduct for possible discipline after determining his brief contained eight nonexistent case citations. Sabatini, a former Florida state representative and Lake County commissioner, previously filed multiple lawsuits challenging local mask mandates, all of which were dismissed. The court found that the brief he filed in a pandemic-era lawsuit on behalf of aviation workers against Atlas Air and Flight Services International relied on at least eight fabricated decisions, including a citation that appeared to be from the 11th Circuit itself. After opposing counsel highlighted the errors, Sabatini acknowledged the citations were erroneous or unverifiable and moved to withdraw eight cases. The court noted that the eight withdrawn cases did not correspond to any of the fabricated citations and were themselves invented. Judges said that relying on artificial intelligence without verification violates professional competence standards. The opinion quoted Chief Justice John Roberts' 2023 year-end report warning that citing nonexistent cases is always a bad idea. The panel concluded that completely outsourcing legal work to AI software is not competent and constitutes a violation of the client's interests. The referral to the disciplinary committee was issued by separate order through the chief judge, and appellate costs were imposed on Sabatini's clients. The case highlights the risk of AI-generated misinformation in legal practice and underscores the need for attorney oversight.
