D.C. Circuit sides with Department of War in classifying Anthropic as risk to national security per 41 U.S.C. § 4713(a). Contrary to decision on “supply chain risk” per 10 U.S.C.

The U.S. Court of Appeals for the D.C. Circuit ruled 2-1 in favor of the Department of War's classification of Anthropic's model as a risk to national security under 41 U.S.C. § 4713(a), distinguishing Judge Rita Lin's earlier finding in the Northern District of California that the department violated Anthropic's First Amendment rights by labeling its models a "supply chain risk" under 10 U.S.C. § 3252. Anthropic remains engaged in two lawsuits against the Department of War.
