New Mexico’s Supreme Court has fined lawyer Stephen Aarons $5,000 and held him in contempt after he submitted an appeal brief containing AI-generated witnesses and fabricated police testimony. The filing for his client’s murder conviction included false statements about the shooter’s clothing and appearance because Aarons failed to verify the factual claims and legal authority in his AI-generated brief. Justice C. Shannon Bacon noted during an August hearing that Aarons should have been aware of the risks posed by artificial intelligence. The court ruled that the brief contained false testimony from wholly fabricated witnesses, which undermined the integrity of the legal process. This penalty marks a specific consequence for relying on unverified machine output in high-stakes litigation rather than a broad policy shift.
The ruling highlights the immediate danger of treating AI summaries as factual records in criminal proceedings. It forces attorneys to confirm every detail before submission. The case serves as a warning against automated drafting without human oversight.
