Judge Rules Pentagon Blacklisting of Anthropic Violates First Amendment
A federal judge rules that the Pentagon's blacklisting of Anthropic earlier this year is unconstitutional, delivering the AI lab a significant win in its monthslong battle with the Trump administration. Judge Rita F. Lin of the Northern District of California finds that the administration's actions amount to unlawful retaliation against Anthropic for setting "red lines," or unacceptable military use cases of its AI technology.
In her ruling, Judge Lin writes that "the empty invocation of national security is not a blank check to punish and retaliate against government critics." She adds that Defense Secretary Pete Hegseth's decision to designate Anthropic a supply chain risk is "arbitrary and capricious," noting that while the Department of War is free to select the AI vendor of its choice, the broad measures imposed on Anthropic are illegal and baseless.
The dispute begins this past winter, when Hegseth moves to renegotiate all AI labs' military contracts to allow the Pentagon to use AI for any lawful purpose. Anthropic's refusal to drop its restrictions on military use of its technology sparks the standoff, culminating in the March lawsuit and this week's ruling in the company's favor.
