Summary
Attorney Christopher Cervantes of Cervantes Law, P.C., representing plaintiff Vita Law Offices in a referral-fee dispute against Lockridge Grindal Nauen, filed a brief containing fabricated case quotations generated by Microsoft Copilot. Among the invented passages was a quotation attributed to Carden v. Arkoma Associates, 494 U.S. 185 (1990), purportedly addressing diversity jurisdiction. Judge Brian E. Murphy issued an order to show cause after identifying multiple fabricated quotes, and Cervantes acknowledged that he had used Copilot without verifying its output against the underlying authorities.
