Anthropic PBC v. United States Department of War
Issue
In *Anthropic PBC v. United States Department of War*, five civil liberties and technology amici argue that the Pentagon's supply chain risk designation of Anthropic PBC violated the First Amendment on three distinct theories: that the designation compelled Anthropic to alter Claude's design and usage policies (compelled speech), silenced Anthropic's published restrictions on surveillance and autonomous weapons use (compelled silence), and retaliated against Anthropic for protected public criticism of Pentagon demands. The case raises the genuinely unsettled question of whether an AI developer's training choices, published governance documents, and system-level usage policies constitute protected expression — and whether a national security procurement authority can be wielded against a company, at least in part, because of the ideological valence of its product.
What Happened
Filed April 22, 2026, at the merits stage of a D.C. Circuit petition for judicial review under 41 U.S.C. § 4713, this consent amicus brief was submitted on behalf of the Foundation for Individual Rights and Expression, the Cato Institute, the First Amendment Lawyers Association, the Electronic Frontier Foundation, and the Chamber of Progress, all represented by Perkins Coie LLP. The brief argues that Claude's training, Anthropic's published "Claude's Constitution," and its Usage Policy collectively reflect protected editorial judgment analogous to curated media, invoking *Moody v. NetChoice* (2024) and *Hurley* to frame these as constitutionally shielded expressive choices. On retaliation, the amici point to Secretary Hegseth's public characterizations of Anthropic's "ideology" and presidential statements labeling the company "RADICAL" and "WOKE" as facially establishing but-for retaliatory motive under the *NRA v. Vullo* (2024) framework. The brief also contends that the D.C. Circuit's April 8 stay panel applied an erroneously narrow "actual chilling" standard, and urges the merits panel to apply the *Aref v. Lynch* "ordinary firmness" standard instead. Oral argument is scheduled for May 19, 2026.
Why It Matters
This brief pushes the D.C. Circuit toward a significant and unresolved doctrinal question: whether the First Amendment protects not just a developer's written governance documents — which fit comfortably within existing editorial-judgment precedent — but also the design choices embedded in an AI system itself. The retaliation theory, grounded in publicly documented government hostility toward Anthropic's expressed values, is the brief's most legally orthodox argument and tracks the *Vullo* playbook closely enough to warrant serious merits attention. If the D.C. Circuit reaches the AI-expression question, whatever it says will carry substantial weight in future disputes over government leverage over AI developers' product decisions — a dynamic that extends well beyond the procurement context.
