Judge rules the government’s measures against Anthropic were unlawful retaliation

Judge Rita Lin granted Anthropic summary judgment on most of its claims, ruling that the government-wide ban, the bar on military contractors dealing with Anthropic and the supply-chain-risk designation were retaliation for protected speech, in violation of the First Amendment, and denied Anthropic due process. She vacated the designation under 10 U.S.C. § 3252 as arbitrary and capricious, vacated the contractor ban and the measures nine agencies took to carry out the President’s directive, and permanently barred the participating agencies from enforcing them. The opinion says the government’s whole rationale is a four-page memorandum and that the government conceded Anthropic has no backdoor access to its deployed models. The judgment leaves the Department of War free to stop using Anthropic and move to other AI providers.

Why it matters

A federal court has found that the government punished Anthropic for criticising it, and has barred most agencies from enforcing the ban.
