Decided
March 10, 2026

Summary

Pro se plaintiff Michael Platt filed a response brief opposing Volunteers of America Ohio & Indiana's Motion for Leave to File Amended Answer that cited at least one nonexistent case (Bodine v. Warwick Valley Central School District, 2015 WL 1298999) and attributed a quotation to Williams v. Board of Education of City of Chicago, 982 F.3d 495 (7th Cir. 2020) that does not appear in that decision. After VOA's reply brief flagged the defects, Mr. Platt's surreply did not concede fabrication; he argued instead that even if Bodine did not exist it was immaterial to the motion. Magistrate Judge Kellie M. Barr independently searched Westlaw, Lexis, and PACER, confirmed the citations did not exist or were misrepresented, and stated that "The Court suspects that Mr. Platt did so" referring to AI use. The order surveys the S.D. Ind. AI-citation line (Mid Central v. HoosierVac $6,000 sanction; Virgil v. Experian $10,000 recommendation; Davis v. Marion Cnty.; Tsupko v. Kinetic Advantage) and explicitly cites the 7th Circuit's 2026 holding in Jones v. Kankakee County Sheriff's Department that pro se litigants are not excused from Rule 11 compliance.

What sanction did the court impose?

In consideration of Mr. Platt's pro se status, the court declined to issue a Rule 11 show-cause order at this time. Instead, the court STRUCK Mr. Platt's response brief at Dkt. 21 sua sponte and granted him leave to refile within 14 days. The court formally ADMONISHED Mr. Platt that all future filings must FULLY COMPLY with the Federal Rules of Civil Procedure and the Local Rules, with the warning that failure may result in sanctions, "up to and including dismissal of his case." VOA's reply brief at Dkt. 22 and Mr. Platt's surreply at Dkt. 23 will not be considered further. VOA was given 14 days from the refiling to file a new reply.

Why does Platt v. Volunteers of America Ohio & Indiana matter for law firms using AI?

Platt v. Volunteers of America Ohio & Indiana is a clean S.D. Ind. magistrate-judge brief-strike order against a pro se plaintiff whose response to a motion for leave to amend an answer contained nonexistent and misrepresented citations. Magistrate Judge Kellie M. Barr’s March 10, 2026 order is procedurally significant for two reasons. First, the court did not require a Rule 11 motion or sanctions request from VOA; it acted sua sponte under inherent authority once the citations were independently verified to be fabricated. Second, the order operates as a survey of S.D. Ind. AI-citation jurisprudence, citing Mid Central Operating Engineers v. HoosierVac (the foundational $6,000 attorney sanction), Virgil v. Experian (the $10,000 recommendation), Davis v. Marion County Juvenile Detention, and Tsupko v. Kinetic Advantage as the warning-then-sanction pattern for pro se filers.

The remedy here is admonishment plus leave to refile within fourteen days. The court explicitly tied that disposition to Mr. Platt’s pro se status, applying the Tsupko warning-first model. The Jones v. Kankakee County citation matters: the Seventh Circuit’s 2026 holding that pro se litigants “shoulder responsibility too” and cannot include misrepresentations they “reasonably know or should know” exist is now binding authority in the district. A future S.D. Ind. magistrate facing the same pattern from a pro se filer with prior notice could escalate to a Rule 11 show-cause hearing without disturbing the Platt warning model.

For an Indiana firm representing organizational defendants, the operational implication is that a defendant flagging fabricated citations in a reply brief is sufficient to trigger sua sponte striking by the magistrate, even without a separate Rule 11 motion. That’s a low-friction escalation path. It also means the firm’s brief-finalization workflow has to verify each cited case exists in a primary database; the Platt court’s independent Westlaw/Lexis/PACER search is now the documented baseline practice for the district.

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.

  • Cite Platt as the recent S.D. Ind. authority on the admonishment-and-leave-to-refile remedy for first-occurrence pro se AI fabrications, distinct from the higher monetary sanctions imposed on counsel in HoosierVac and Virgil.
  • Document a citation-verification workflow that confirms each cited case exists in Westlaw, Lexis, or PACER before any filing leaves the firm; the Platt court explicitly performed this check independently.
  • Train staff that S.D. Ind. magistrate judges will act sua sponte on fabricated citations, even where opposing counsel has only flagged the issue without moving for sanctions.
