Judge rules Pentagon’s supply chain risk designation against Anthropic was unlawful

A U.S. District Court judge in Northern California ruled that the Department of Defense’s designation of Anthropic as a supply chain risk was unlawful, finding the company’s AI products posed no meaningful threat to national security. Judge Rita Lin concluded the Pentagon’s actions amounted to unlawful retaliation and violated Anthropic’s Fifth Amendment due process rights, including the requirement for pre-deprivation process.

The dispute centered on the Pentagon’s use of Anthropic’s technology in agency missions, including mass surveillance and autonomous weaponry. Lin’s judgment stated that the Pentagon’s broad measures against Anthropic were ‘illegal and baseless,’ rejecting the argument that the company’s products justified its exclusion from government contracts.

The ruling also addressed the Pentagon’s public statements, which Anthropic argued reflected retaliation for the company’s concerns about how its technology was used. Lin found that the administration’s invocation of national security was not a ‘blank check’ to punish critics, emphasizing that an IT vendor does not become an adversary simply for advocating for specific contracting terms or questioning government use cases.

Anthropic welcomed the decision, with a spokesperson stating the company remains focused on collaborating with the government to advance national security applications of AI. The Pentagon did not respond to requests for comment by publication time.

The case underscores broader uncertainty among technology vendors regarding government contracting practices under the Trump administration. Industry groups, such as the Information Technology Industry Council, hailed the ruling as a step toward clarifying the boundaries of executive authority in disqualifying vendors.

The ruling arrives amid heightened scrutiny of AI vendors’ relationships with the Pentagon, including concerns about single-vendor dependencies. Defense Under Secretary for Research and Engineering Emil Michael previously stated the Pentagon would ‘never again’ rely on a single AI vendor, a remark referenced in the judgment.
