Federal Judge Rules Pentagon’s Anthropic Blacklist Illegal and Baseless

U.S. District Judge Rita F. Lin ruled that Pentagon measures designating Anthropic a national-security supply-chain risk and barring federal agencies and defense contractors from using the company violated the Constitution and federal law. The 59-page order granted Anthropic summary judgment on its First Amendment, due-process and principal Administrative Procedure Act claims. Lin found the government’s four-page rationale lacked a valid factual basis and that officials acted to make an example of Anthropic for criticizing the government. She called the measures “illegal and baseless” and said a separate order on relief would follow.
