- Appeal (Bloomberg, Oct 26, 2026, paywalled; read through search summaries): on Oct 26 the Justice Department filed a notice of appeal with the 9th Circuit against Judge Rita F. Lin’s August ruling that the administration had not justified barring federal agencies from using Anthropic’s technology. The government’s earlier appeal of Lin’s March 26 preliminary injunction had been stayed on April 27 pending the D.C. Circuit case, where Anthropic is seeking en banc review of the 2–1 September ruling
What happened
The ruling followed the March 26 preliminary injunction in Anthropic’s suit against the Defense Department.
