A federal court fight over Donald Trump administration layoffs has become the latest example of AI hallucinations entering the courtroom. Attorney Jason Greaves admitted in a declaration filed Friday that the filing included fabricated quotations generated after he used Anthropic's Claude Console to help prepare the motion.

"Given the tight time constraints I used an enterprise level, data-isolated AI platform, Claude Console, to create an initial draft of the motion. That was a mistake," Greaves wrote. He noted an associate failed to fully verify the citations. Greaves took full responsibility and apologized to the court and opposing counsel.

The case adds to a growing list of AI-related courtroom disputes, including a recent sanction against Sullivan & Cromwell for similar AI-generated fake legal citations. This latest controversy stems from lawsuits against the Trump administration over mass federal layoffs and proposed changes to civil service protections.
