Brock et al. v. Hamilton County JFS Children Services et al.
S.D. Ohio · May 15, 2026
What happened in this matter?
The Court issued a formal warning to the pro se plaintiff after identifying that she used artificial intelligence to generate fabricated case law citations in her court filings. The judge explicitly cautioned that future misrepresentations of legal precedent would lead to the imposition of sanctions.
- Why the court cared
- The Court reasoned that the plaintiff's reliance on a miscited and misrepresented case (Jansen v. City of Cincinnati) indicated the use of AI tools without proper verification. The Court determined that the citation was factually incorrect and the case content was irrelevant to the plaintiff's claims, necessitating a formal warning regarding future filings.
- Why it matters now
- This case illustrates judicial scrutiny of pro se filings for AI-generated hallucinations. It establishes a clear precedent for courts to issue formal warnings when litigants fail to verify AI-generated legal research, signaling a low tolerance for citation errors.
Why this matter is tracked
In a civil rights action challenging state child custody proceedings, the pro se plaintiff submitted objections to a Magistrate Judge's report and recommendation. The Court found that the plaintiff's legal arguments relied on a fabricated case citation, specifically misrepresenting Jansen v. City of Cincinnati, 904 F.3d 336, as a Sixth Circuit case addressing § 1983 claims against child welfare workers. The Court noted that the cited volume and page actually correspond to a Fifth Circuit habeas case, and the actual Jansen case (904 F.2d 336) concerns city employment quotas. The Court explicitly attributed this error to the plaintiff's use of artificial intelligence tools and issued a formal warning that future misstatements of precedent would result in sanctions.

Tracked discrepancy record

- Fabricated: Case Law | Plaintiff cited Jansen v. City of Cincinnati, 904 F.3d 336, claiming it held that §1983 claims against child welfare workers for fabricating evidence are not barred by Rooker-Feldman; the Court found the citation incorrect (904 F.3d 336 corresponds to Gilkers v. Vannoy, a Fifth Circuit case) and that Jansen is 904 F.2d 336 (1990) and does not address child welfare or that holding.
