An anonymous reader quotes a report from The Guardian: A US judge ruled on Thursday that the Trump administration broke the law when it designated Anthropic as a supply chain risk earlier this year, finding that the government had unlawfully targeted the AI firm for refusing to comply with defense department demands. "The empty invocation of national security is not a blank check to punish and retaliate against government critics," Judge Rita Lin said in a 59-page decision. Lin's ruling barred the federal agencies named in the lawsuit from enforcing Donald Trump's order to stop using Anthropic's tools and overturned the designation of the company as a "supply chain risk" by the defense secretary, Pete Hegseth. The status, usually reserved for foreign firms, would have blocked government agencies from doing business with Anthropic. The case emerged out of a months-long feud between Anthropic and the Pentagon at the start of the year. Anthropic refused to allow the government to use its Claude AI model for fully autonomous lethal weapons or domestic mass surveillance, resulting in Hegseth accusing the company of "arrogance and betrayal". Lin put a temporary pause on the government's punitive measures in March, stating that the government's actions looked like an attempt to "cripple Anthropic" for exercising its first amendment rights. The ruling this week makes that temporary suspension permanent, although the government may appeal. "We welcome the court's ruling that this supply chain risk designation was unlawful," an Anthropic spokesperson said.Read more of this story at Slashdot.
