An assistant U.S. attorney filed a court response containing fabricated quotations and false case citations, which may have been generated by AI, leading to a show-cause hearing and potential sanctions.
Assistant U.S. Attorney Rudy Renfer from the Eastern District of North Carolina filed a response brief in a case involving TRICARE weight loss medication policy that included fabricated quotations and misstatements of case holdings from multiple circuit court opinions, as well as fabricated quotes from the Code of Federal Regulations. U.S. Magistrate Judge Robert Numbers identified these issues after they were flagged by the opposing party, retired Air Force Colonel Derence Fivehouse, who is representing himself pro se. When confronted, Renfer claimed he 'inadvertently included incorrect citations to caselaw' and attributed the errors to 'inadvertent filing of an unfinalized draft document.' Judge Numbers expressed serious concerns about the accuracy of quotations and representations in Renfer's filings and the explanation offered. The incident comes amid increasing reports of attorneys using AI tools that generate fabricated legal citations, though it is not explicitly confirmed whether AI was used in this case. Judge Numbers ordered senior leaders from the U.S. Attorney's Office to appear at a show-cause hearing to explain why the office shouldn't be held jointly responsible and why Renfer shouldn't be sanctioned. Potential sanctions range from fines to contempt proceedings or suspension from practicing before the court.
