Lawyer sanctioned for false AI-generated testimony in brief

The New Mexico Supreme Court held attorney Stephen Aarons in contempt and fined him for submitting a legal brief, prepared with ChatGPT, containing fabricated police testimony and invented witnesses in a murder conviction appeal. The court found Aarons did not verify the AI-generated content or inform his client about the falsehoods. He has been referred to a disciplinary board for further review.
