# New Mexico lawyer fined $5,000 over AI-hallucinated witnesses in murder case

*2026-09-11 · Source: [The Verge](https://www.theverge.com/ai-artificial-intelligence/994207/chatgpt-new-mexico-lawyer-fined-murder-appeal)*

New Mexico's Supreme Court fined attorney Stephen Aarons $5,000 and held him in contempt after he submitted an appeal brief containing AI-fabricated witness testimony and false details in a client's murder conviction case. The court said Aarons failed to verify the factual claims and legal authority generated by the AI tool.

**Why it matters:** It's another entry in a growing string of court sanctions over unverified AI-generated legal filings, this time in a serious criminal case, underscoring that courts are increasingly willing to impose real financial and professional penalties rather than warnings.
