Federal Court Overturns Trump-Era Ban on Anthropic, Citing Retaliation

A federal district court in the Northern District of California has invalidated the Trump administration’s placement of artificial intelligence company Anthropic on the National Security Supply Chain Risk List. In a ruling issued last March, Judge Rita Lin determined the action was unlawful and constituted unconstitutional retaliation against the company for its public objections to how its technology could be deployed.

What the court found unconstitutional

Judge Lin concluded that the government’s move violated the First Amendment of the U.S. Constitution, which protects freedom of expression. She stated that the administrative record in the case demonstrated the decision was not grounded in legitimate national security concerns but instead amounted to unlawful retaliation for Anthropic’s stated policy positions.

The court held that the administration could not formally invoke national security justifications to penalize a company solely because it publicly objected to certain terms of use for its technology. The ruling explicitly voided federal directives that had imposed a permanent ban on all federal agencies’ use of Anthropic’s products and prohibited Department of Defense contractors from engaging with the company—even for work unrelated to military operations.

Background of the dispute

The legal challenge stems from negotiations between Anthropic and the Pentagon that took place last February concerning expanded use of the Claude large language model in defense and intelligence missions. Anthropic did not oppose military collaboration in principle; rather, it had already served as one of the leading AI model suppliers to sensitive U.S. government entities, with its technology applied in information analysis, operational planning, simulation, and cyber operations.

During those talks, Anthropic maintained two specific conditions: first, that Claude would not be used for mass surveillance of Americans within the United States; second, that it would not power fully autonomous weapons systems capable of selecting and engaging targets without human intervention.

The court’s decision marks a significant judicial rebuke of executive authority to restrict commercial AI firms under national security pretexts when those restrictions appear tied to protected speech.
