Summary

However, this outline contained “bogus AI-generated research” when it was sent to a separate law firm, K&L Gates, which added the information to a brief. “No attorney or staff member at either firm apparently cite-checked or otherwise reviewed that research before filing the brief,” Judge Milner writes. The lawyer who created the outline admitted to using Google Gemini, as well as the AI legal research tools in Westlaw Precision with CoCounsel. A judge also found that lawyers suing a Colombian airline included a slew of phony cases generated by ChatGPT in their brief. “The initial, undisclosed use of AI products to generate the first draft of the brief was flat-out wrong,” Judge Milner writes.
