Ioio v. City of New York
U.S. Court of Appeals for the Second Circuit · 2d Cir. · Connecticut bar guidance , New York bar guidance , Vermont bar guidance
Conduct
Here the appellants' corrected opening brief cited two New York state decisions that the panel said do not appear to exist, and no near-match suggested a typo.
Consequence
Merits affirmed; no fine, but the panel referred attorneys Jo Saint-George and Tricia S. Lindsay to the Second Circuit's Grievance Panel under Local Rule 46.2.
Lesson
Here a short citation finding in an unpublished summary order produced a grievance referral, and a later S.D.N.Y. court relied on it in sanctioning one of the lawyers.

Summary
Dozens of plaintiffs, represented by Jo Saint-George of Women of Color for Equal Justice, appealed an Eastern District of New York order (Komitee, J.) that dismissed most of their claims challenging the City's COVID-19 vaccine mandates and denied their motion for Rule 11 sanctions against the defendants. In the part of the corrected opening brief arguing that a violation of a federal civil rights statute is per se a violation of the New York City Human Rights Law, the appellants cited two "leading" New York state court decisions. The panel wrote that "[t]he two citations provided for those two decisions, however, do not appear to exist, nor could we locate decisions resembling those citations closely enough to suggest mere typographical errors," and quoted Park v. Kim that Rule 11 requires attorneys to "read, and thereby confirm the existence and validity of, the legal authorities on which they rely." The panel also pointed to a separate problem from the district court record: a letter from Mark Whitsett, whom counsel had purported to represent as a plaintiff, stating that he had told Saint-George he was not interested in participating before she filed the case.
- AI tool:
- Unidentified (the summary order says two citations in the opening brief "do not appear to exist" but does not mention AI or any tool)
- Amount or terms:
- None imposed; attorneys Jo Saint-George and Tricia S. Lindsay referred to the Second Circuit's Grievance Panel under Local Rule 46.2
How did the court address the AI-related conduct?
In a summary order, the panel affirmed the district court: claims under the Occupational Safety and Health Act fail because the Act gives employees no private right of action, the constitutional claims fail under circuit precedent upholding COVID-19 vaccine mandates, and the NYCHRL claim fails with them. It held it lacked jurisdiction over the recusal and class-certification rulings, which the notice of appeal did not designate, and found no abuse of discretion in the denial of sanctions against the Appellees. It then stated that "[t]here is evidence, however, that Appellants' counsel used false citations in their opening brief to this Court and purported to represent as a plaintiff in this action someone who expressly asked not to be involved," and referred attorneys Jo Saint-George and Tricia S. Lindsay to the court's Grievance Panel under Local Rule 46.2 "for further investigation, and for consideration of a referral to the Committee on Admissions and Grievances." The order imposes no fine or other sanction itself.
Why does Ioio v. City of New York matter for law firms using AI?
The Second Circuit’s treatment of the citations takes up two sentences and a footnote in an otherwise routine affirmance of a COVID-19 vaccine-mandate dismissal. Addressing the appellants’ argument that a federal civil rights violation is automatically a violation of the New York City Human Rights Law, the panel noted that the appellants had asserted “in conclusory fashion” that two “leading” New York state court decisions supported that point, and then that the citations “do not appear to exist, nor could we locate decisions resembling those citations closely enough to suggest mere typographical errors.” The panel did not name the citations, did not ask how they were produced, and did not mention artificial intelligence.
The consequence is a referral rather than a sanction. The panel found no abuse of discretion in the district court’s refusal to sanction the Appellees, then turned to the appellants’ own counsel: “There is evidence, however, that Appellants’ counsel used false citations in their opening brief to this Court and purported to represent as a plaintiff in this action someone who expressly asked not to be involved.” It referred both Jo Saint-George and Tricia S. Lindsay to the Grievance Panel under Local Rule 46.2 for investigation and possible referral to the Committee on Admissions and Grievances. The order cites Park v. Kim for the Rule 11 duty; see Park v. Kim for that court’s own referral. The order pairs the citation problem with a client-authority problem drawn from the district court record, so the referral does not rest on the citations alone.
The order’s reach shows up in a later case. In Jimenez-Fogarty v. Fogarty, Magistrate Judge Gorenstein of the Southern District of New York quoted this referral paragraph, examined the two flagged citations himself, and treated Lindsay’s filing of the Second Circuit brief after his show-cause orders as evidence of bad faith in the $2,500 Rule 11 sanction he imposed on her there.
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 every authority cited for a contested proposition. The panel tested the two cases offered for the NYCHRL point, could not find them or anything close enough to suggest a typographical error, and cited Park v. Kim's rule that attorneys must confirm the existence and validity of the authorities they rely on.
- Document client consent before naming a person as a plaintiff. The same referral paragraph relied on a letter from Mark Whitsett, whom counsel had purported to represent as a plaintiff, who said he had declined to participate before the case was filed.
- Consider that an appellate referral can travel. The S.D.N.Y. court in Jimenez-Fogarty v. Fogarty quoted this order when it found bad faith and sanctioned Tricia S. Lindsay in a separate matter.

- AI attribution: the summary order does not mention artificial intelligence; it says only that the two citations 'do not appear to exist.' This case is not in the Charlotin tracker, so no tracker inference exists either. The entry is included because the order itself addresses nonexistent citations and refers counsel to the Grievance Panel.
- The order does not identify the two nonexistent citations by name, and it does not say which of the two referred attorneys signed or drafted the brief; it lists only Jo Saint-George as counsel for the appellants.
