Judge Rules Trump Administration Illegally Retaliated Against Anthropic

US district judge Rita Lin said the Defense Department acted unlawfully when it told firms to boycott the AI company

A US judge has ruled that the Trump administration illegally retaliated against the AI company Anthropic, which has been at loggerheads with the Pentagon over the use of AI by the US military.

In its lawsuit, Anthropic argued that Defense Secretary Pete Hegseth had overstepped his authority. In February, the Pentagon designated the company as a supply-chain risk, a law typically reserved for companies based in countries that pose a threat to the US. It was the first time an American company had been publicly designated in this way. The move followed Anthropic's refusal to allow the military to use its AI models for purposes including surveillance or autonomous weapons.

US district judge Rita Lin said in the ruling that citing national security "is not a blank check to punish and retaliate against government critics". She said the Defense Department had acted unlawfully when it ordered firms that do business with the military to boycott Anthropic. In an earlier round in the case, she said the government was trying to "cripple" the company and "chill public debate", adding: "This appears to be classic First Amendment retaliation."

The Claude-maker said its models were not reliable enough to be used safely in weapons systems, and that it opposed their use for domestic surveillance as a violation of rights. The Pentagon said at the time that private companies should not be able to constrain military action, and argued that Anthropic's refusal to accept new contract terms raised concerns about what the company could do with its technology.

Anthropic welcomed the ruling. A spokesperson told the BBC the company was focused on "working productively with the government to harness AI for our national security so all Americans benefit from this technology". The BBC has contacted the Pentagon and the White House for comment.
