Judge rules US DoD acted unlawfully against AI firm Anthropic

A U.S. district judge today declared the Department of Defense’s designation of AI startup Anthropic as a supply‑chain risk illegal and based on an unjustified overreach of authority.

The ruling follows the company’s lawsuit, which argued that Defense Secretary Pete Hegseth overstepped his power by denying the Pentagon the right to use Anthropic’s models—an act that the firm said was not “reliable enough for weapons systems” and would violate civil‑rights protections if used for domestic surveillance.

Judge Rita Lin said the Pentagon’s reliance on “national security” was “not a blank check to punish and retaliate against government critics.” The court highlighted that the agency was essentially “trying to cripple” the company to chill public debate about AI in the military, labeling the conduct “classic First Amendment retaliation.”

Anthropic welcomed the decision and stated it is dedicated to working with the U.S. government to harness AI for national security in a responsible manner. The judge’s findings are expected to shape future government interaction with technology firms and may provide a precedent for defending civil‑speech rights in the tech sector.
