Mitchell Taylor Button et al. v. John Jimison (1)
W.D. Washington · Oct 17, 2025
What happened in this matter?
The Court sanctioned the Plaintiffs for submitting fabricated case law and quotes, likely generated by AI. The order requires Plaintiffs to include a signed certification on all future filings confirming the validity of every cited decision and the accuracy of all quoted language, under penalty of having non-compliant filings stricken.
- Why the court cared
- The Court determined that Plaintiffs' filings contained multiple non-existent cases and misattributed quotes, violating the duty of accuracy under Federal Rule of Civil Procedure 11. The Court reasoned that a mandatory certification requirement was necessary to ensure the integrity of future submissions and to address the apparent reliance on artificial intelligence for legal research.
- Why it matters now
- This case illustrates the judicial response to AI-generated hallucinations in pro se litigation. It establishes a clear procedural control—a mandatory certification of authority—that courts may impose to mitigate the risk of fabricated citations and ensure compliance with Rule 11.
Why this matter is tracked
In Mitchell Taylor Button et al. v. John Jimison, the U.S. District Court for the Western District of Washington addressed Plaintiffs' use of fabricated case law and non-existent quotes in their reply brief. The Court identified multiple instances where Plaintiffs cited non-existent cases or misattributed language to existing opinions, noting that such errors likely resulted from the use of artificial intelligence. While the Court granted the motion to strike the Defendant's answer to allow for an amended filing, it imposed a specific procedural sanction on the Plaintiffs. The Court ordered that all future filings by Plaintiffs must include a signed certification verifying the validity of every cited decision and the accuracy of all quoted language, warning that non-compliant filings will be stricken.
