A federal judge in the District of Connecticut sanctioned solo practitioner Hilary B. Miller $3,500 and referred her to the Federal Grievance Committee for potential disciplinary action after filings she submitted in a trademark dispute misstated case holdings and contained erroneous citations. Miller had used three separate AI tools, including Claude and ChatGPT, to help draft the filings. The judge found that although Miller expressed remorse and promised to change her verification process, her conduct still showed subjective bad faith, and the affected filings were struck from the docket.
