New Mexico lawyer fined for using AI-generated brief containing fabricated police testimony

Stephen Aarons said he tried to use ChatGPT to create a'bulletproof summary' during a murder conviction appeal A defense lawyer appealing his client's murder conviction submitted a legal brief containing made-up police testimony and witnesses fabricated by OpenAI's ChatGPT, New Mexico's highest court said. The New Mexico supreme court on Wednesday fined the attorney, Stephen Aarons, and held him in contempt for failing to verify the accuracy of the court filing, which Aarons said he prepared with help from the artificial intelligence ( AI) application. The filing "contained false testimony from wholly fabricated witnesses", the court said. The panel also said Aarons had "demonstrated a lack of remorse and a lack of concern for his client". The justices fined Aarons $5,000 and said they will refer him to an attorney disciplinary board for investigation.
