New Mexico lawyer fined $5,000 for AI-fabricated testimony in murder appeal
The New Mexico Supreme Court fined defense lawyer Stephen Aarons $5,000 and held him in contempt after he filed an appeal brief containing fake police testimony and nonexistent witnesses generated by ChatGPT. Aarons said he did not know the chatbot could invent facts. The court is also requiring him to notify his client and other parties about the fabricated content.
WHY IT MATTERS ↘Sanctions like this establish that liability for unverified model output falls on the professional who files it, not the vendor, which raises the cost of deploying general-purpose chatbots in regulated work and strengthens demand for retrieval-grounded tools that cite verifiable sources. It also gives courts a template for graduated penalties that other jurisdictions and regulators are likely to copy.
