San Francisco federal judge orders sworn explanation after a lawyer files a motion he says Claude Console drafted with three phantom quotations
In the federal lawsuit over the Trump administration's mass layoffs (AFGE v. Trump, Northern District of California), a partner at Binnall Law Group filed an emergency motion on the night of 6 May 2026, in the Eastern District of Virginia, to quash a deposition subpoena directed at a former Homeland Security official the firm represents; that court transferred the motion to the Northern District of California. On 13 May Judge Susan Illston denied the motion. Her order says the court was troubled by multiple citations to case quotations that do not exist in the cases cited, that counsel was unaware of these quotations when questioned at the hearing and had no explanation for them, and it ordered counsel to explain the fabricated quotations in a declaration under penalty of perjury by 15 May. In that declaration the partner said he had used Claude Console, an enterprise AI platform, to create an initial draft, that an associate told him she had checked the citations, and that he did not double-check the quotations. He apologised to the court and opposing counsel and attached a corrected version. The firm's founding partner declared that firm policy prohibits using tools like Claude for legal drafting, that the error breached its policies and training, and that the firm had opened an internal investigation. On 20 Oct 2026 the court administratively closed the related miscellaneous case, saying the motion had been adjudicated and no further filings were anticipated. Neither order read mentions a sanction, and whether one was imposed is not established.
