A federal judge has ruled that the US Department of Defense acted unlawfully when it designated artificial intelligence startup Anthropic a supply chain risk, finding the move violated the company's constitutional rights and was taken as retaliation for its public criticism of the government.
US District Judge Rita Lin issued the ruling on 27 August, determining that Defense Secretary Pete Hegseth lacked adequate legal basis for the designation and that citing national security concerns
is not a blank check to punish and retaliate against government critics. According to reporting on the decision, the judge found evidence that the government had taken the action to make a
public exampleof Anthropic for its opposition to military use of its technology.
The Claude-maker had challenged the designation in court, arguing that Hegseth exceeded his authority. The company refused to allow the military to deploy its AI models for surveillance or autonomous weapons systems, citing both technical limitations and ethical concerns. The judge found that Hegseth's designation violated the governing statutory scheme and was arbitrary and capricious.
What was the supply chain risk designation?
The Pentagon invoked a law designed to protect military systems from foreign sabotage when it branded Anthropic a supply chain risk. This marked the first time an American company had been publicly designated in this manner. The government argued that private companies should not be able to constrain military action, and the White House characterized Anthropic as
a radical left, woke companyattempting to control military activity, asserting that
the military was beholden to the US Constitution, not any woke AI company's terms of service.
How did this case begin?
Anthropic filed its lawsuit in March 2026, alleging that the Trump administration violated its First Amendment rights and exceeded the scope of the supply-chain-risk law by weaponizing the designation against the company. The company's executives estimated that the move could cost billions of dollars in lost business and reputational harm. In June 2026, Hegseth denied Anthropic's request for internal reconsideration, clearing the way for judicial review of the designation.
The ruling came after months of escalating tensions between the AI firm and federal authorities. The court ordered the Trump administration to lift the ban on Anthropic's AI technology for federal agencies. The company had previously suspended public access to its advanced Claude Fable 5 model following government restrictions on foreign access and security concerns about potential vulnerabilities.
What happens next?
The case remains in further court proceedings beyond the preliminary injunction phase, with the broader lawsuit continuing toward final resolution. The ruling represents a significant legal victory for Anthropic in its dispute with the federal government over the company's right to refuse military applications of its technology.
