A federal judge in California has ruled that the government's decision to label Anthropic a supply chain risk was unlawful, marking an important legal milestone for the AI company.
U.S. District Judge Rita Lin said the designation amounted to unlawful retaliation and violated constitutional protections, including the First and Fifth Amendments. In her view, the measure was not supported by solid evidence and did not meet the standard of fair process.
The dispute began after the Defense Department and the Trump administration restricted federal agencies from working with Anthropic, the maker of Claude. The company had set clear safety boundaries around how its models could be used, especially in areas involving autonomous weapons and mass surveillance.
Judge Lin also noted that the government's own actions appeared inconsistent with the risk label, pointing to continued interest in working with Anthropic on cybersecurity and other defense-related uses. She wrote that national security cannot be used as a blanket justification to punish criticism.
Anthropic said it welcomed the ruling and remained open to productive collaboration with the government on AI systems that can serve public interests. The company's separate case in Washington, D.C. is still ongoing.
This ruling may help shape how governments and AI companies negotiate safety, accountability, and innovation in the years ahead.
