A US federal judge has ruled that the Trump administration unlawfully blacklisted AI company Anthropic as a national security supply-chain risk, finding that the move amounted to retaliation after the firm publicly opposed Pentagon demands over how its technology could be used.
A US federal judge has ruled that the Trump administration acted unlawfully when it blacklisted AI company Anthropic as a national security supply-chain risk, finding that the move amounted to retaliation over the company's protected speech and violated its First Amendment rights.
US District Judge Rita F. Lin of the Northern District of California mostly sided with Anthropic in its lawsuit against the Trump administration.

The ruling concerns sanctions imposed after Anthropic refused to remove restrictions on how its Claude AI models could be used by the US government.
The administration subsequently designated Anthropic as a national security supply-chain risk and directed federal agencies to stop using its products.
Judge Lin found that the government's action constituted unlawful retaliation against Anthropic for exercising its First Amendment rights.
What triggered the Anthropic-Pentagon dispute?
The dispute centred on Anthropic's safety restrictions for its AI models.
Anthropic had maintained restrictions against using its technology for lethal autonomous warfare without human oversight and mass surveillance of US citizens.
The Department of Defense sought access to Claude for what it described as "all lawful uses". Anthropic declined to remove its restrictions.
The disagreement escalated when the administration moved to blacklist the company.
The court rejected the government's attempt to rely on national security concerns as sufficient justification for its actions.
Judge Lin wrote that "the empty invocation of national security is not a blank check to punish and retaliate against government critics."
The ruling found that Anthropic's public positions on AI safety and ethics, including statements and essays by CEO Dario Amodei, involved matters of public concern and were protected speech.
Government also violated due process, court says
The judge also found problems with the government's procedures.
According to the ruling, Anthropic was not given adequate advance notice, evidence or an opportunity to respond before being designated a supply-chain risk.
The court also found that the Department of Defense had bypassed established statutory procedures for such designations, making the process legally flawed.
What does the ruling mean for Anthropic?
The decision represents a significant legal victory for Anthropic in its dispute with the US government.
It also establishes that the government's national security powers cannot automatically be used to penalise a company because it publicly disagrees with government policy.
The ruling comes amid a broader debate in the US over how powerful AI systems should be deployed for military, surveillance and national security purposes.
Why the case matters for AI companies
The Anthropic case goes beyond one company's commercial dispute with the Pentagon. It raises questions about how far the US government can go when dealing with technology companies whose safety policies conflict with government demands.
The ruling also highlights the tension between AI safety safeguards and military requirements, particularly as governments increasingly seek access to advanced AI systems.
For technology companies, the case could influence how they negotiate contracts with government agencies and defend their own policies on the use of AI in sensitive areas.
