Arizona Tribune - US court expedites Anthropic's legal battle with Department of War

"On one side is relatively contained risk of financial harm to a single private company," the three-member appellate panel here reasoned.

"On the other side is judicial management of how, and through whom, the Department of War secures vital AI technology during an active military conflict."

The ruling stems from the Pentagon designating Anthropic, creator of the Claude AI model, as a national security supply chain risk -- a label typically reserved for organizations from unfriendly foreign countries.

The AI startup sought a stay of the action in appellate court here and also sued the Department of War in federal court in Northern California.

The appellate panel stated in its ruling that requiring the Department of War to prolong its use of Anthropic AI directly or through contractors "strikes us as a substantial judicial imposition on military operations."

However, the appeals court agreed that Anthropic raised "substantial challenges" to the sanctions and ordered that proceedings in the underlying case be expedited.

"We're grateful the court recognized these issues need to be resolved quickly and remain confident the courts will ultimately agree that these supply chain designations were unlawful," an Anthropic spokesperson told AFP.

"While this case was necessary to protect Anthropic, our customers, and our partners, our focus remains on working productively with the government to ensure all Americans benefit from safe, reliable AI."

In the suit filed in San Francisco, federal Judge Rita Lin temporarily froze the sanctions, reasoning that President Donald Trump's administration likely violated the law in blacklisting the AI powerhouse for expressing unease about the Pentagon's use of its technology.

In her ruling, she said the government's designation of Anthropic as a supply chain risk was "likely both contrary to law and arbitrary and capricious."

The dispute erupted in February after Anthropic infuriated Pentagon chief Pete Hegseth by insisting its technology should not be used for mass surveillance or fully autonomous weapons systems.

The tech sector has largely supported Anthropic in the wake of the punitive measures.
