New Mexico lawyer fined for using AI-generated brief containing fabricated testimony
The New Mexico Supreme Court fined and held defense attorney Stephen Aarons in contempt after he submitted an appeal brief in a murder case that contained fabricated police testimony and invented witnesses generated by ChatGPT. Aarons said he used the AI tool to build what he described as a bulletproof summary, but did not verify the filing's accuracy before submitting it.
Why this matters: A man's murder conviction was being appealed, and his lawyer handed the court made-up witnesses. That is not a tech story. It is a story about someone's freedom resting on fiction that no one caught before it was filed. AI does not know what is true. It produces text that looks authoritative and can be completely wrong. Lawyers have always been responsible for what they file. That has not changed. What has changed is that it is now easy to generate confident-sounding nonsense at speed, and some people are skipping the step where they check.
