The Trump Administration’s decision to punish Anthropic for its stance forbidding Claude’s use in domestic surveillance and autonomous weapons by identifying it as a supply chain risk to national security was “arbitrary and capricious,” a federal judge ruled on Thursday.
US District Court Judge Rita Lin said federal authorities had no legitimate reason to tell companies with government contracts that they couldn’t work with Anthropic.
“The undisputed record shows that the challenged actions constituted unlawful retaliation in violation of the First Amendment and that Anthropic was denied the pre-deprivation process required under the Fifth Amendment,” Lin said in her ruling, calling the designation “arbitrary and capricious.”
She stressed that the government action seemed punitive, and was not based on legal and national security risks.
The government’s words and deeds “confirm that the challenged actions were based on a desire to make a public example out of Anthropic for its ‘arrogance’ in criticizing the government, not based on any articulable basis to believe that Anthropic would actually sabotage its model,” Lin wrote.
She pointed out, “a few days before the challenged actions began, Secretary Hegseth proposed applying the Defense Production Act to Anthropic, which would mean the company was essential to national security rather than a threat to it. Even now, the government is discussing collaboration with Anthropic on its new model, Mythos, in an array of sensitive contexts. None of that is consistent with a genuine fear that Anthropic is a saboteur [that] would poison its software to harm national security.”
The judge added that the stated government fears made no sense, noting that the usage policy applicable to Pentagon work is a purely contractual limit. “Anthropic is incapable of enforcing it technologically, and does not have direct visibility into how DoW [Department of War] uses its model,” she pointed out.
“Nothing in the Administrative Record describes, even at a high level, what technological means would give rise to the so-called ‘backdoors’ or could otherwise allow Anthropic to ‘disable’ or affect Claude during a DoW operation,” the judge wrote. “Anthropic has submitted unrebutted evidence that it lacks any technological means to access or control deployed models.”
Lawyers, consultants, and analysts who looked at the decision were confident that the case would be appealed, and that it will end up in the US Supreme Court.
Alan Webber, program VP for national security, defense, and intelligence at IDC, said that Lin’s ruling “was that the label [supply chain risk] was retaliation for Anthropic refusing to loosen safety guardrails DoD [Department of Defense, aka the Department of War] wanted lifted, dressed up in national security language. Put another way, a government customer tried to use a supply chain risk designation as leverage in a contract dispute over model behavior and application, and not because of an actual vulnerability.”
Webber said the implications for CIO strategy are concerning.
“If a government CIO is relying on a vendor’s contractual guardrails, this case says those commitments can potentially become the trigger for exactly the kind of blacklisting that risk registers are supposed to protect against,” Webber said, noting that anyone who paused Claude usage or froze a subcontract because of the DoD mandate has a legal basis to resume the initiatives. “But obviously that doesn’t mean they will, or even should, as this will be appealed.”
He added that competing AI vendors have been using the government action as a sales tool, and with this ruling, the argument that Anthropic is a designated supply chain risk ”just got weaker, which could lead to contract award disputes.”
Consultant Brian Levine, executive director of FormerGov, recommended that CIOs do what they should have always done: Evaluate all products based solely on their merits.
“CIOs should focus on using the frontier models that they believe make the most sense for their business, considering factors such as effectiveness, cost, security, safety, and confidentiality,” he said. “Anthropic and the other large frontier models each have too much market share to make retaliation for their use realistic, and the administration seems to have already moved on from this particular battle.”
