Judge pauses Anthropic ban
A judge ruled Anthropic is not a supply‑chain risk and paused Pentagon efforts to bar the company from US military contracts, a decision reported on March 27 (x.com). The ruling removes an immediate legal hurdle to Anthropic’s defense work while the dispute continues to play out (x.com).
U.S. District Judge Rita F. Lin issued a preliminary injunction on March 26, 2026 in the Northern District of California, halting the Pentagon’s supply‑chain designation in a 43‑page order. (Politico.com ) Lin’s order said punishing Anthropic for public criticism of the government’s contracting position amounted to “classic illegal First Amendment retaliation,” language she used to justify blocking the administration’s measures. (CNBC.com ) The judge found Anthropic likely to succeed on three legal theories — First Amendment retaliation, violations of the Administrative Procedure Act, and Fifth Amendment due process — in the company’s challenge to the designation. (TechCrunch.com ) Lin stayed her order for seven days to give the Justice Department time to seek emergency relief and ordered the government to file a report by April 6 detailing how it will comply with the injunction. (Politico.com ) Anthropic filed its suit on March 9, 2026 in case No. 3:26‑cv‑01996, challenging actions taken after President Donald Trump on Feb. 27 directed federal agencies to stop using Anthropic’s Claude and Defense Secretary Pete Hegseth labeled the company a supply‑chain risk. (CourtListener.com USA Today ) The Pentagon’s designation would have forced major defense contractors to certify they do not use Claude — names cited in reporting included Amazon, Microsoft and Palantir — and several agencies, including Treasury and State, began moving to phase out Anthropic tools after the February directive.
