What Did The Anthropic Pentagon Ban Ruling Actually Say?
The D.C. Circuit Court of Appeals sided 2-1 with the Defense Department, rejecting Anthropic's argument that the designation was arbitrary and unlawful.
Judges Gregory Katsas and Neomi Rao formed the majority, while Judge Karen LeCraft Henderson dissented.
The opinion states that Anthropic builds restrictions into Claude that block certain government tasks, which the panel called ample support for the Anthropic national security risk label, framing Claude national security risk concerns as central to the case.
The Hill reported that undersecretary Emil Michael publicly welcomed the decision.

Circuit Anthropic ruling made it permanent.

Key points from the case so far:
A separate California federal ruled last month that a related designation was unlawful, creating a split outcome.
Anthropic said in a statement it respectfully disagrees and is reviewing options.
The panel gave Anthropic a window before the ruling takes full effect.
