Court Rules Pentagon's Blacklist of Anthropic Unlawful, Citing First Amendment
A federal judge has issued a ruling blocking the Pentagon from designating Anthropic as a supply chain risk, stating that this action likely constitutes illegal retaliation against the AI company. The ruling, delivered by US District Judge Rita F. Lin, found that the Department of Defense's blacklisting of Anthropic appears to violate the First Amendment. In her 43-page opinion, Judge Lin described the government's actions as "classic illegal First Amendment retaliation," emphasizing the distinction between legitimate national security concerns and punitive overreach.
The conflict originated from Anthropic's refusal to comply with Pentagon requests to remove safety guardrails from its AI models. The company declined to permit its technology to be used for surveillance or autonomous lethal weaponry, aligning with its public commitments to AI safety.
On February 27, Defense Secretary Pete Hegseth escalated the situation by formally designating Anthropic as a supply chain risk, a label that had never been applied to a US company before. This designation effectively barred Anthropic from participating in defense contracting, coinciding with negotiations over a $200 million Department of Defense agreement.
In response, Anthropic filed lawsuits in both the Northern District of California and the D.C. Circuit on March 9, arguing that the designation was unlawful retaliation and suffered from procedural defects. Judge Lin sided with Anthropic, granting a preliminary injunction and indicating that the company was likely to succeed on its First Amendment claim. Her opinion pointed to a significant discrepancy between the government's national security rationale and the timeline of events, suggesting retaliation rather than a genuine risk assessment.
Meanwhile, a three-judge panel in the D.C. Circuit denied Anthropic's emergency stay request on April 8, favoring governmental equities and citing ongoing military operations. This ruling did not address the merits of Anthropic's claims but reflected a more deferential stance toward executive authority in defense matters.
This case is unprecedented, as no US company has previously received a supply chain risk designation of this nature, which is typically reserved for foreign adversaries or entities with known security vulnerabilities. At its core, the dispute raises critical questions about the governance of AI and the extent to which the government can impose conditions on companies seeking defense contracts, particularly regarding safety-oriented usage restrictions.
