A Pennsylvania lawyer has been sanctioned for submitting fabricated legal cases generated by artificial intelligence in a product liability lawsuit involving Colgate-Palmolive Co. The lawyer cited nonexistent case law created by AI, specifically ChatGPT, which led to judicial concern over AI-generated 'hallucinations' in legal filings. The issue escalated when the plaintiff repeatedly referenced fake AI-generated cases in court documents, prompting Amazon to highlight these inaccuracies in a motion to dismiss. The court issued an order to show cause regarding potential sanctions after the lawyer continued to submit fabricated cases. At a hearing, the lawyer admitted that the motion was drafted using AI, and the statement read in court was also AI-generated. This incident has drawn attention to the risks of relying on artificial intelligence tools for legal research and case preparation.
