Anthropic Faces Legal Setback as Appeals Court Upholds Pentagon Blacklisting
Anthropic, the AI company behind the Claude model, has suffered a significant legal blow in its battle with the U.S. Government. A federal appeals court in Washington, D.C., has denied the company’s request to pause the Department of Defense’s (DOD) decision to blacklist the firm as a supply chain risk.
- A D.C. Federal appeals court refused to block the Pentagon’s “supply chain risk” designation of Anthropic.
- The ruling allows the DOD to continue excluding Anthropic from defense contracts.
- A separate San Francisco court ruling previously barred the Trump administration from banning Claude’s use across the broader federal government.
- The appeals court prioritized national security and military operations over the financial harm to the private company.
A Divided Judicial Landscape
The legal battle between Anthropic and the U.S. Government is currently split between two different courts ruling on two different supply-chain laws. This has created a complex environment where the company is simultaneously restricted and permitted in different areas of government operations.
The D.C. Appeals Court Ruling
On Wednesday, a three-judge appellate panel in Washington, D.C., ruled that Anthropic failed to meet the “stringent requirements” necessary to temporarily lift its supply-chain-risk designation. The court emphasized that the “equitable balance” favored the government, noting that the risk of financial harm to a single company was outweighed by the need for the Department of War to secure AI technology during an active military conflict. According to CNBC, the court stated it would not “lightly override” military judgments on national security.
The San Francisco Preliminary Injunction
In a contrasting development, a judge in a San Francisco federal court granted Anthropic a preliminary injunction in a separate but related case. This ruling barred the Trump administration from enforcing a ban on the use of the Claude model. As reported by Wired, the San Francisco judge found that the DOD likely acted in bad faith, driven by frustration over Anthropic’s proposed limits on how its technology could be used and the company’s public criticism of those restrictions.
Current Operational Impact
Because of these conflicting rulings, Anthropic’s ability to work with the U.S. Government is currently fragmented:
- Department of Defense: Anthropic remains excluded from DOD contracts. Defense contractors are prohibited from using Claude in their work specifically for the agency.
- Other Federal Agencies: Due to the San Francisco injunction, Anthropic can continue working with other government agencies, and access to its AI tools has been restored throughout the rest of the federal government.
Why This Matters
This case is described as “unprecedented” because Anthropic is the first U.S. Company to be designated as a supply-chain risk under laws typically reserved for foreign businesses that threaten national security. The outcome of this litigation will likely set a precedent for how the U.S. Government manages “unwanted vendors” of critical AI services and the extent to which the judiciary will defer to military judgment during active conflicts.
Frequently Asked Questions
What is a “supply chain risk” designation?
It is a sanction used by the government to identify vendors that may pose a risk to national security, effectively blacklisting them from receiving government contracts.
Can the military still use Claude?
While the broader federal government can use the tools, the D.C. Appeals court ruling ensures that the Pentagon’s blacklist remains in effect, restricting the military’s use of Anthropic’s services.
What happens next?
The litigation continues as both sides fight over the merits of the supply-chain designations. The conflict between the San Francisco, and D.C. Rulings remains a point of legal uncertainty.
