Akerlund v. Atlas Air, Inc.
U.S. Court of Appeals for the Eleventh Circuit · 11th Cir. · Alabama bar guidance , Florida bar guidance , Georgia bar guidance
Conduct
Counsel filed an opening brief with at least eight hallucinated cases, then 'withdrew' eight different cases that were also hallucinated.
Consequence
Dismissal affirmed in a published opinion finding counsel violated his duties to client and court; referral to the Eleventh Circuit's discipline committee announced.
Lesson
A correction filing needs the same verification as the original: here the reply listed eight cases to withdraw that matched none of the originals and were themselves hallucinated.

Summary
Employees in the commercial aviation business sued Atlas Air, Inc. and Flight Services International, LLC over their pandemic-era masking, testing, and vaccination policies, asserting Title VII hostile work environment, Federal Food, Drug, and Cosmetic Act, constitutional, and Florida tort claims. The district court dismissed the third amended complaint. On appeal, the Eleventh Circuit found that plaintiffs' counsel Anthony F. Sabatini "filed multiple briefs replete with fake and hallucinated citations. Even after being warned." His opening brief relied on at least eight nonexistent cases, including one purportedly decided by the Eleventh Circuit. After the defendants identified the problem, Sabatini's untimely proposed reply brief acknowledged that those citations were "erroneous or unverifiable" and sought to withdraw reliance on eight listed cases. In the Court's words, "things go from bad to worse: the eight cases Sabatini 'withdrew' did not match a single one of the eight hallucinated cases in his opening brief." The Court added that all eight withdrawn cases were also hallucinated.
- AI tool:
- AI tools, not named (the Court found counsel was "outsourcing his legal work to an AI algorithm" and filed "briefs generated by AI tools")
- Amount or terms:
- None imposed in the opinion; the Court stated that, in a separate order, it will, through the Chief Judge, refer the matter to the Committee on Lawyer Qualifications and Conduct
How did the court address the AI-related conduct?
In a published opinion by Judge Grant, the panel affirmed the dismissal of the third amended complaint for lack of personal jurisdiction over Flight Services International and for failure to state a claim against Atlas Air. In Part V, the Court held that "completely outsourcing one's legal work to artificial intelligence software is not competent," called it "a dramatic violation of the client's interests," and concluded that by signing briefs filled with hallucinated citations "not once but twice," Sabatini "violated his professional obligations, both to his clients and to this Court." It stated that "[i]n a separate order, this Court, through the Chief Judge, will refer the matter to the Committee on Lawyer Qualifications and Conduct," citing 11th Cir. Rules, Addendum 8, Rule 2(C). The opinion itself imposes no monetary sanction, fee award, or strike.
Why does Akerlund v. Atlas Air, Inc. matter for law firms using AI?
Akerlund is a merits affirmance with a disciplinary coda, and the coda is written for other lawyers to read. Judge Grant opens the opinion by explaining why it is “more candid than usual” about the weakness of the claims: “because the plaintiffs’ counsel Anthony F. Sabatini has not been candid with us.” The opinion then saves its account of the briefing “for last,” describing it as “blatant and repeated misconduct” of a kind that is “rare to see.”
The facts in Part V are what make the case distinctive. The opening brief relied on at least eight hallucinated cases. When the defendants pointed this out, counsel’s untimely proposed reply acknowledged that the citations were “erroneous or unverifiable” and listed eight cases he was withdrawing. None of the eight matched the hallucinated cases in the opening brief, and all eight of them were hallucinated too. A footnote adds that one case appeared in both filings but was attributed to a different court in the reply.
The Court’s reasoning rests on competence and on the lawyer’s role as an officer of the court. It cited Model Rule 1.1 and ABA Formal Opinion 512 for the proposition that “completely outsourcing one’s legal work to artificial intelligence software is not competent,” and it explained what is lost when a lawyer “is willing to sign his name on whatever a machine churns out without so much as checking it for accuracy.” “Whatever the merits of artificial intelligence,” the Court wrote, “it is no substitute for actual intelligence.” When lawyers use AI tools, “there is no way to get around the obligation to verify that the software got it right.” Firms documenting compliance may wish to consider that the remedy here was a published, named rebuke and a referral, not a fine.
Implications for your firm
Operational steps a firm reading this case may wish to consider documenting. Strategic and rule-application calls belong to your firm's attorneys.
- Verify any correction or withdrawal filing against the original brief. The Court found the eight cases counsel withdrew matched none of the eight hallucinated cases in the opening brief, and were themselves hallucinated.
- Document review of AI output before signature. The Court held that 'completely outsourcing one's legal work to artificial intelligence software is not competent,' citing Model Rule 1.1 and ABA Formal Opinion 512.
- Consider the client-facing consequences. The Court described completely outsourcing one's legal work to artificial intelligence software as 'a dramatic violation of the client's interests,' and wrote that if counsel 'thinks these claims are not worth the effort, he should either tell his clients they fall short or advise them to hire another lawyer.'
- Train lawyers that published criticism can follow even without a monetary sanction. The opinion names counsel and announces a disciplinary referral by separate order.
