Judge Rita Lin of the US District Court for the Northern District of California granted Anthropic a preliminary injunction against the measures taken after it refused to drop its limits on mass surveillance and fully autonomous weapons: the President’s order that every federal agency stop using Anthropic, Secretary Hegseth’s order that companies doing business with the military cut commercial ties with Anthropic, and the Department of War’s supply-chain-risk designation. The order says the Department may stop using Claude and choose another vendor, and that the case is about whether the government broke the law when it went further. The injunction was stayed for seven days so the government could seek a stay from the court of appeals.

Why it matters

A federal judge found Anthropic likely to win its claim that the government-wide ban was unlawful, and barred agencies from carrying it out for now.
