Summary
Plaintiffs' attorney filed a response to defendants' motion to dismiss in a student disability and harassment case that cited nonexistent cases and attributed unsupported legal propositions to real cases on multiple occasions. Judge Colleen R. Lawless observed in a footnote that certain cited cases "d[id] not appear to exist, along with many others," and that other citations referenced cases where "[a]lthough the case exists, the quote does not, and the proposition the case is cited for was not a point of discussion."

- Generative AI inferred (court did not require formal AI-use finding; cited the AI-fabrication pattern of nonexistent cases and unsupported propositions)
What sanction did the court impose?
No sanction imposed in this order; instead a forward-looking warning: "any future citation to nonexistent cases, cases for legal propositions not discussed or supported, or other false representations to the Court will result in a show cause hearing and consideration of sanctions." The court granted in part and denied in part the defendants' motion to dismiss on other grounds.
Why does Feldman v. District 6 Board of Education matter for law firms using AI?
Feldman v. District 6 Bd. of Educ. is C.D. Ill.’s representative warning-only response to first-occurrence AI-citation conduct, with the warning embedded in a footnote to the merits ruling on the underlying motion to dismiss. Judge Lawless’s framing identifies two distinct AI-pattern problems: nonexistent cases (“d[id] not appear to exist, along with many others”), and misrepresentation of real cases (“[a]lthough the case exists, the quote does not, and the proposition the case is cited for was not a point of discussion”).
The court’s warning is forward-looking: future false citations will trigger a show-cause hearing and consideration of sanctions. The warning does not impose a fee, strike, or formal disclosure requirement on the present filing. This positions Feldman as a template for first-occurrence calibration: counsel can avoid sanctions on first detection if (and only if) subsequent filings comply.
The procedural posture is notable in another way. The court’s AI-pattern observation appears in a footnote to a merits ruling on the motion to dismiss; the AI conduct is not the subject of a separate sanctions proceeding. This footnote-disclosure mechanism makes detection essentially free for the court (the AI citations are noticed during routine motion review) and the warning-or-sanction calibration follows from the court’s discretion at that moment. Counsel handling matters in C.D. Ill. should treat this as a one-strike framework: first occurrence may draw a warning, second will trigger show-cause.
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.
- Lawless's warning-only response on first occurrence is the calibrated end of the C.D. Ill. AI-citation enforcement spectrum. Firms in C.D. Ill. with first-time AI conduct should be prepared to argue for the warning-only template; the precedent is now in place.
- The footnote disclosure mechanism (court flags AI-pattern citations in a footnote to the merits ruling without converting it to a separate sanctions proceeding) is a procedurally light-touch device counsel should anticipate. The cost of detection is functionally zero to the court, which means counsel cannot assume undetected AI conduct will pass through routine motion practice.
- The warning's specificity matters: 'nonexistent cases, cases for legal propositions not discussed or supported, or other false representations' captures both fabrication and misrepresentation. Counsel should treat each prong as independently sanctionable in subsequent filings.
