Key Facts
- District Judge Rita Lin ruled that the Pentagon illegally designated Anthropic as a supply chain risk to national security.
- The 59-page written order was issued on Thursday night.
- The designation was the first time a US company has been publicly labelled a supply-chain risk under an obscure procurement statute.
- Anthropic executives have said the ban could cost the company billions of dollars in lost business.
The Court Order
District Judge Rita Lin ruled that the Department of Defense acted illegally when it designated Anthropic a supply chain risk to national security. The 59-page written order was issued on Thursday night. Lin wrote that the empty invocation of national security is not a blank check to punish and retaliate against government critics. Lin, an appointee of former President Joe Biden, described the government's position as really troubling and at odds with the First Amendment during a July 30 hearing.
Anthropic's Lawsuit
Anthropic's lawsuit in a California federal court alleges that Defense Secretary Pete Hegseth overstepped his authority when he designated the company a national security supply-chain risk. Hegseth's move, which blocked Anthropic from military contracts, followed the company's refusal to allow the military to use its Claude AI models for US surveillance or autonomous weapons. Anthropic argues that AI models are not reliable enough for autonomous weapons and opposes domestic surveillance. The Pentagon maintains that private companies should not constrain military action.
Government Response
The government is expected to fight the ruling. Department of Justice lawyers argued that the nature of AI models is so staggeringly enormous and opaque that the Pentagon cannot evaluate them like physical hardware. Anthropic welcomed the ruling, stating it remained focused on working productively with the government to harness AI for national security.
