$31,000 Sanction in Lacey v. State Farm Tied to Purportedly Undisclosed Use of LLMs and Erroneous Citations

2025-04-15

In the case of Lacey v. State Farm, two law firms were sanctioned $31,000 after submitting a legal brief containing reportedly erroneous citations generated using AI tools. The court reportedly found that the lawyers failed to disclose the use of AI, neglected to verify its output, and refiled a revised brief with additional inaccuracies. Judge Michael Wilner deemed the conduct reckless and issued sanctions for what he described as "improper" and "misleading" legal filings.
