Judge voids Trump administration ban on Anthropic

A U.S. district judge has struck down the Trump administration’s ban on Anthropic, ruling the government’s restriction was unlawful and cannot be enforced.

The court order vacates the specific prohibition the administration had imposed on the San Francisco-based AI company and removes that legal barrier to the company’s activities while the ruling stands.

The judge concluded the executive branch exceeded its statutory authority and failed to meet required administrative procedures. The opinion focused on the scope of legal power to impose the ban and on procedural defects in how the restriction was issued.

The challenged restriction had been justified by the government on national security and safety grounds. Anthropic argued the ban was arbitrary, lacked a statutory basis and was implemented without required procedures. The court resolved the legal questions presented in favor of Anthropic.

The ruling affects contracts, transactions and international collaborations that were paused under the restriction. Entities that suspended dealings with Anthropic can point to the court order as removing the specific legal impediment created by that ban.

The decision addresses only the legality of the particular restriction at issue. It does not prevent the government from pursuing future regulatory or enforcement actions under other authorities or through new procedures.

Anthropic was founded by former AI researchers and develops large language models and related products. The dispute highlights legal questions about how existing statutes govern executive action to restrict technology companies on national security or safety grounds.

Legal filings in the case laid out the administration’s rationale and Anthropic’s challenge; the court’s opinion resolved the parties’ claims as presented in that litigation.
