New Mexico Supreme Court Fines Defense Attorney $5,000 Over AI-Hallucinated Witnesses in Murder Appeal
The New Mexico Supreme Court has sanctioned defense attorney Stephen Aarons, imposing a $5,000 fine and holding him in contempt after he submitted an artificial intelligence-generated brief containing fictitious witnesses and fabricated police testimony in an appeal for his client's murder conviction. The court's ruling follows a finding that Aarons failed to verify the factual accuracy and legal authority produced by AI tools, which also introduced erroneous descriptions concerning the shooter's appearance and clothing. During proceedings, high court justices, including Justice C. Shannon Bacon, scrutinized the attorney's apparent lack of awareness regarding generative AI hallucination risks. The case marks a significant judicial escalation in penalizing unverified AI usage in high-stakes criminal justice matters.
