- On August 28, U.S. District Judge Rita Lin ruled that the Pentagon's designation of Anthropic as a "supply chain risk" was unlawful retaliation that violated the First Amendment and denied the company due process.
- The Defense Department had ordered all federal agencies, including non-defense ones, to stop working with Anthropic after the company refused to let Claude be used for fully autonomous weapons and mass surveillance of Americans.
- The ruling is Anthropic's first courtroom win in the fight, but a separate case in Washington remains open, and Defense Secretary Pete Hegseth can still challenge the decision.
A judge calls the blacklisting retaliation
A federal court has struck down the Trump administration's move to cut Anthropic out of government contracting. In a ruling issued the evening of August 28, U.S. District Judge Rita Lin found that Defense Secretary Pete Hegseth's designation of Anthropic as a "supply chain risk" was "unlawful retaliation" against the company for publicly defending limits on how its AI could be used.
The dispute began in February 2026, when President Donald Trump and Hegseth accused Anthropic of endangering national security and ordered every federal agency to stop using its products. The trigger was Anthropic's usage policy, which barred the Pentagon from deploying Claude for fully autonomous weapons systems and for mass surveillance of American citizens. The Pentagon argued the company was trying to dictate how the military used models it had already paid for. Anthropic filed two lawsuits in March, one in California and one in Washington.
Judge Lin sided with the company on nearly every point, ruling the designation was "arbitrary and capricious" and that it stripped Anthropic of its Fifth Amendment due process rights. She found the government acted out of a desire to punish, not out of any real belief that Anthropic would sabotage its models.

Why the ruling reaches past Anthropic
The decision matters beyond one company because it tests whether a lab can hold a usage line against its most powerful customer. Anthropic drew a boundary on autonomous weapons and surveillance, and the government responded by trying to end its federal business entirely. By blocking that response, the court has signaled that a safety policy is protected speech, not grounds for a blacklist.
The win is partial. Judge Lin's order is an injunction, the parallel Washington case is unresolved, and the administration retains room to appeal or to recast its objection on narrower grounds. Anthropic, which said it welcomed the ruling that the designation "was unlawful," now has legal cover to keep selling to agencies while the broader question, how far a private company can restrict government use of the AI it sells, moves toward a decision that every frontier lab will be watching.
