MyPillow Defense Lawyers in Coomer v. Lindell Reportedly Sanctioned for Filing Court Document Allegedly Containing AI-Generated Legal Citations

Judge fines Mike Lindell’s attorneys for filing AI-generated motion during defamation case
denver7.com · 2025

A judge fined two attorneys for MyPillow CEO Mike Lindell $3,000 apiece Monday for filing a motion riddled with AI-generated errors in a case that resulted in a jury finding Lindell liable for defamation over false claims that the 2020 presidential election was rigged.

Judge Nina Y. Wang, of the U.S. District Court in Denver, found attorneys Christopher I. Kachouroff and Jennifer T. DeMaster violated court rules when they filed a motion that featured numerous errors, including misquotes from caselaw and citations from nonexistent cases.

Kachouroff acknowledged using generative artificial intelligence to draft a motion during a pretrial hearing after the mistakes were found.

Kachouroff initially argued that the error-ridden motion was filed by mistake. However, the version that Kachouroff said was the correct one still contained “substantive errors,” including some that weren’t in the filed version of the motion, and it had timestamps that did not align with his claims, Wang found.

She said “contradictory statements and the lack of corroborating evidence” failed to persuade her that the AI-assisted filing was an inadvertent error, versus sanction-worthy negligence.
