On 2026-03-30, U.S. District Court for the Northern District of Illinois ordered counsel to file a statement explaining the nonexistent quotations, the Engquist misstatement, and whether the same source caused other errors. Counsel submitted a response brief with two false quotations, fabricated or nonexistent authorities and mischaracterized authorities.
- Disposition
- The court denied the Board's motion to dismiss the ADEA claim, granted the motion to dismiss the other claims without prejudice, set pleading and discovery deadlines, and required Williams's counsel to file a statement explaining the misquotations and misrepresentation.
- Recorded conduct
- Williams's response brief contained two nonexistent quotations attributed to EEOC v. University of Chicago Hospitals and Doe v. Village of Arlington Heights, cited Engquist for a class-of-one theory even though it held public employees cannot bring such claims, and misrepresented other holdings. — outcome: pending; actor: lawyer
- Canonical record
- Incident tracker entry — verified outcome, regulator disposition and related rules
What the court wrote
Verbatim from the court's document (public domain). Ellipses mark omitted text; nothing is paraphrased.
Arlington Heights, 782 F.3d 911, 917 (7th Cir. 2015): “not every governmental activity that might incidentally prevent crime constitutes ‘police protection service’ within the meaning of section 4-102.’” Pl.’s Resp. Br. at 9. But this quote does not exist. This kind of totally made-up quotations might very well be hallucinated quotations from generative artificial intelligence. What’s more, the brief severely misrepresents the holdings of several other cases, well beyond just an aggressive reading of a holding. For instance, the brief cites Engquist v. Oregon Department of Agriculture, 553 U.S. 591, 598 (2008), to support Williams’s “class-of-one” equal-protection claim. Pl.’s Resp. Br. at 7. But Enquist held that public employees like Williams cannot bring class-of-one claims. Perhaps there are reasonable explanations for how these problems came to be. But because these issues appear throughout the response brief, the Court requires Williams’s counsel to provide a Statement of Explanation to explain (1) how the three identified problems happened (the two non-existent quotations and the citation to Engquist); and (2) whether the source of the problems caused other similar problems in the response brief. The Statement is due by April 13, 2026. V.
