Pizzimenti v. City of Detroit, et al.
E.D. Michigan · Mar 27, 2026
What happened in this matter?
The court issued a formal warning to the pro se plaintiff regarding the inclusion of factitious citations and fabricated quotes in his filings. Although the court did not impose monetary sanctions, it explicitly stated that it would have issued an order to show cause regarding sanctions had the case not been dismissed on other grounds.
- Why the court cared
- The court reasoned that the plaintiff's inclusion of factitious citations and fabricated quotes wasted judicial resources and violated the obligation of litigants to ensure filings are scrupulously accurate. The court noted that while pro se litigants may use AI to offset disadvantages, they remain responsible for the accuracy of their submissions.

Why this matter is tracked
In a civil rights action, the pro se plaintiff submitted filings containing multiple factitious case citations and fabricated quotes, which the court attributed to the potential use of generative AI. The court identified several nonexistent cases, including 'Williams v. City of Cleveland' and 'Thaxton v. City of Pontiac,' as well as misrepresentations of real authority, such as 'Opulent Life Church v. City of Holly Springs.' While the court ultimately dismissed the case on other grounds, it issued a formal warning to the plaintiff, noting that had the case survived the motion to dismiss, it would have initiated proceedings to consider sanctions for the submission of inaccurate and hallucinated legal research.
