What courts did to lawyers who cited cases that do not exist
5 min read

Sixteen sanctions orders from 2023 to 2026: the court, what was cited, what it ordered and the rule it used. And how to check that a case exists before you file.
The orders
Since Mata v. Avianca, Inc., 678 F. Supp. 3d 443 (S.D.N.Y. 2023), courts have sanctioned lawyers for filing briefs that cite cases which do not exist, most of them written with a generative tool nobody checked. Damien Charlotin's database listed 2,044 such decisions worldwide on 19 September 2026, 1,397 of them American. These are the orders that set the pattern.

What the courts used, and what they ordered
- Rule 11(b)(2) in the district courts: a signature certifies the legal contentions are warranted, and a case that does not exist warrants nothing. Fines ran from $2,000 to $31,100.
- Inherent power and local rules of professional conduct where Rule 11 did not fit, and FRAP 38 and 46 in the courts of appeals, which added punitive amounts and referrals to the chief judge.
- Beyond money: the order sent to the client, letters to the judges named as authors of invented opinions, disqualification from the case, referral to the bar, and in Nebraska suspension pending a hearing.
- The Fifth Circuit considered an AI-specific rule and declined to adopt one; the existing rules already reached the conduct.

How to check that a case exists
- Open the case at its reporter, volume and first page, on Westlaw, Lexis, or free at CourtListener. Not a search for the name: the page.
- Confirm the case name, the court and the year against the parenthetical. A real case at the wrong year or court is the second most common error.
- Find the pincite and read the passage you are citing it for. Fabricated quotations inside real cases were sanctioned in Gauthier, Fletcher and Farris.
- For a Westlaw or Lexis citation, confirm the docket number and date as well; the identifier alone proves nothing.
- Wrong
- Varghese v. China Southern Airlines Co., 925 F.3d 1339 (11th Cir. 2019).
- Right
- No case is reported at 925 F.3d 1339 under that name. Do not cite it.
Questions people ask
- Can you be sanctioned for citing a case that does not exist?
- Yes. Courts have used Rule 11, their inherent power, FRAP 38 and 46, and state analogues, imposing fines, fee awards, disqualification, bar referrals and, in one state, suspension. The orders above are the record.
- How do I verify a citation is real?
- Open the opinion at the reporter, volume and page cited and confirm the name, court, year and the passage you rely on. A name search is not enough; a fabricated citation often borrows a real name.
- Does Rule 11 apply to citations generated by AI?
- Rule 11 applies to the signer, however the brief was written: the signature certifies the legal contentions are warranted. The Fifth Circuit considered an AI-specific rule and declined to adopt one.
