Calvin Bradley v. Matthew Eichhorn, et al.
S.D. Ohio · Sep 11, 2025
What happened in this matter?
The court issued a formal warning to a pro se litigant after identifying that the plaintiff submitted inaccurate case law citations, which the court suspected were generated by AI. The court cautioned that future reliance on non-existent or inaccurate authorities could lead to sanctions.
- Why the court cared
- The court reasoned that the cited cases (State v. Parker and State v. Gonzales) did not support the plaintiff's propositions, were misidentified by district/court level, and were irrelevant to the legal issue of post-legalization K-9 searches. The court linked these errors to the known propensity of generative AI to hallucinate.
- Why it matters now
- This case illustrates judicial scrutiny of pro se filings for AI-generated hallucinations. It establishes that courts are actively monitoring for AI-sourced inaccuracies and will issue formal warnings to deter the submission of fabricated legal authority.
Why this matter is tracked
In a pro se civil rights action, the Magistrate Judge conducted an initial screening of the complaint under 28 U.S.C. § 1915(e)(2). The court identified that the plaintiff cited two non-existent or mischaracterized Ohio appellate cases to support a legal argument regarding K-9 searches. The court noted an influx of pro se filings using generative AI and suspected the plaintiff's inaccurate citations resulted from AI hallucination. Consequently, the court issued a formal warning to the plaintiff, cautioning that future submissions relying on inaccurate or non-existent authorities may result in sanctions, while simultaneously recommending the dismissal of several claims for failure to state a claim.
This case illustrates judicial scrutiny of pro se filings for AI-generated hallucinations. It establishes that courts are actively monitoring for AI-sourced inaccuracies and will issue formal warnings to deter the submission of fabricated legal authority.

Parker, 2018-Ohio-4210, 2d Dist." for the proposition that K-9 alerts cannot establish probable cause post-legalization; the court found the citation actually corresponds to State v.
