The Justice Department filed a notice of appeal to the Ninth Circuit on 26 October 2026 against Judge Rita Lin’s 27 August judgment, which held that the government-wide ban on Anthropic, the bar on military contractors dealing with it and its supply-chain-risk designation were unlawful. The appeal is filed for 35 agencies and officials, among them the Department of War and Secretary Hegseth. In the separate case over the Department’s exclusion order, which a D.C. Circuit panel upheld on 25 September, Anthropic petitioned for rehearing by the full court on 13 October; the court gave the government until 13 November to respond.

Why it matters

The ruling that stopped the government-wide ban on Anthropic now goes to the Ninth Circuit while the D.C. Circuit weighs rehearing on the Pentagon’s exclusion.
