Missoula judge, public defender clash over AI use

TL;DR

The story at a glance

A Missoula County public defender, Monica Tranel, filed a motion on February 9, 2026, to dismiss a burglary case for client Justin Stroup that contained undisclosed AI-generated text, prompting prosecutor Justin Ekwall to move to strike it for violating Fourth Judicial District rules. Judge John Larson vacated a trial date without ruling on the AI issue, as the defense withdrew the filing and refiled a corrected one. This is being reported now due to a recent follow-up clash over broader AI use in court filings by the public defender's office.[[1]](https://www.msuexponent.com/news/state/defense-attorney-monica-tranel-caught-violating-ai-rules-in-case-filing/article_36e5ed91-42af-5279-90ea-e130115c8b0e.html)

Key points

Details and context

The incident stems from national issues with generative AI "hallucinations" creating fake case citations in hundreds of court filings, prompting districts like Montana's Fourth to mandate disclosures for accuracy and privacy.[[1]](https://www.msuexponent.com/news/state/defense-attorney-monica-tranel-caught-violating-ai-rules-in-case-filing/article_36e5ed91-42af-5279-90ea-e130115c8b0e.html)

Ekwall requested the court order the public defender's office to review past filings for undisclosed AI, disclose tools used, and certify compliance—part of an escalating dispute over AI integration in Missoula courts.[[1]](https://www.msuexponent.com/news/state/defense-attorney-monica-tranel-caught-violating-ai-rules-in-case-filing/article_36e5ed91-42af-5279-90ea-e130115c8b0e.html)

Tranel's memo to staff views AI as a "force multiplier" for client advocacy but stresses discipline and transparency per rules; the burglary case involves a defendant with paranoia and delusions, heightening stakes for reliable filings.[[1]](https://www.msuexponent.com/news/state/defense-attorney-monica-tranel-caught-violating-ai-rules-in-case-filing/article_36e5ed91-42af-5279-90ea-e130115c8b0e.html)

Key quotes

Why it matters

AI tools promise efficiency in overloaded public defender offices but risk errors, fake facts, and data breaches in criminal cases with confidential info.

This means courts must enforce rules strictly to protect defendants' rights and case integrity, while attorneys adapt without compromising security.

Watch for Judge Larson's order to show cause, potential sanctions, and if the district expands AI audits or rules amid rising use.[[1]](https://www.msuexponent.com/news/state/defense-attorney-monica-tranel-caught-violating-ai-rules-in-case-filing/article_36e5ed91-42af-5279-90ea-e130115c8b0e.html)
