**Denver, CO** – Two Colorado lawyers are facing potential disciplinary action and sanctions after submitting a legal brief riddled with errors generated by artificial intelligence. The brief, filed on behalf of MyPillow CEO Mike Lindell in a defamation lawsuit, contained nearly 30 defective citations, including misquotes, misrepresentations of legal principles, and citations to non-existent cases.

Judge Nina Wang of the Colorado district court identified the issues and ordered attorneys Christopher Kachouroff and Jennifer DeMaster to explain why they should not face disciplinary proceedings. Kachouroff admitted to using AI to draft the brief but claimed he did not verify the citations. Initially, the lawyers claimed they were unaware of the errors. However, in a subsequent filing, they attributed the issues to mistakenly submitting an earlier, flawed draft. They provided an alternate version and an email exchange as evidence.

While the lawyers argue that using AI in legal work is acceptable when done properly, their explanation has not appeased the court. The judge’s order demands an explanation for why they should not be sanctioned alongside Lindell and their firm. This incident follows a string of similar cases involving lawyers using AI tools like ChatGPT and Google Bard to generate legal filings, resulting in the citation of fabricated cases. Despite warnings from legal professionals and firms, this case highlights the ongoing challenge of responsibly integrating AI into legal practice. The lawyers have requested permission to refile a corrected brief and the dismissal of potential disciplinary action. The court will determine the next steps in the coming weeks.
