First Amendment Preliminary Injunction

Anthropic PBC v. U.S. Department of War

🏛 U.S. District Court for the Northern District of California · 📅 2026-03-09

Issue

Whether the Executive Branch violated the First Amendment by retaliating against Anthropic — through an unprecedented supply-chain-risk designation and government-wide blacklisting — because of Anthropic's public advocacy for safe and responsible AI use and its refusal to remove contractual restrictions on use of its AI model for lethal autonomous warfare and mass surveillance.

What Happened

Anthropic filed suit alleging that after it declined to remove contract terms restricting use of its frontier AI model for lethal autonomous warfare and mass surveillance of Americans, the President issued a directive targeting the company for its purportedly "Radical Left" and "WOKE" views, and the Secretary of War designated Anthropic as a supply-chain risk under 10 U.S.C. § 3252 — the first such designation ever applied to an American company — and ordered defense contractors to immediately cease doing business with Anthropic. In this reply brief in support of its motion for a preliminary injunction, Anthropic argues it is likely to prevail on three grounds: (1) the government's actions constituted First Amendment retaliation targeting protected speech (Anthropic's public advocacy, CEO statements, legislative testimony, and contract negotiating positions); (2) the Secretary's designation and secondary-boycott directive violated the APA as arbitrary, procedurally flawed, and in excess of statutory authority; and (3) the Presidential Directive violated due process and separation of powers by blacklisting Anthropic without statutory or constitutional authority. Anthropic invokes NRA v. Vullo and the three-part retaliation framework, arguing the government's own documents confirm that the adverse actions were expressly motivated by Anthropic's "rhetoric" and "ideology."

Why It Matters

This case presents a direct application of the government-coercion/retaliation doctrine — rooted in Bantam Books, Backpage v. Dart, and NRA v. Vullo — to an AI developer being punished by the Executive Branch for its expressed views on AI safety policy, extending the jawboning framework beyond platform moderation contexts to government contracting retaliation against a major AI company. If the court grants the injunction, it will be a significant precedent establishing First Amendment limits on the government's use of procurement and supply-chain authority to punish AI companies for their public policy positions and product design choices.
