# US Appeals Court Upholds Anthropic's National Security Threat Status

## 🎯 Key Points

- The Washington court upheld Anthropic's national security threat designation.
- The dispute arose from the company's refusal to use AI for battlefield target selection.
- A California court previously ruled in favor of the startup, creating a legal contradiction.
- Anthropic retains the right to appeal the verdict to the U.S. Supreme Court.

A federal appeals court in Washington has issued a landmark ruling, upholding the designation of artificial intelligence developer Anthropic as a national security threat source. This verdict marks a new twist in the prolonged legal standoff between the tech startup and the U.S. Department of Defense, which unfolded against the backdrop of company leaders refusing to integrate their advanced language models into military planning processes and battlefield targeting.

The conflict between the agency and the developers began in March of this year when the Pentagon first officially assigned the startup this status. This resulted in the immediate termination of existing contracts and the imposition of strict bans prohibiting all military contractors from using Anthropic's developments for the U.S. military. The stance of the startup's founders, including Dario Amodei, based on their fundamental reluctance to hand over control of AI solutions to the military without veto power, drew sharp condemnation from the country's political leadership.

### Contradictory Data

The situation regarding the company's legal status has become convoluted due to conflicting rulings from different judicial instances. In late August, a federal appeals court in California sided with Anthropic, ruling the Pentagon's actions illegal and unjustified. However, for full rehabilitation and cancellation of sanctions, the startup needed to achieve success in two independent legal battles. Unlike the California verdict, the Washington court voted two-to-one to support the Department of Defense's position, deeming the agency's arguments regarding supply chain risks and information security entirely convincing.

During the court session, Presiding Judge Gregory Katsas and Judge Neomi Rao agreed with Defense Secretary Pete Hegseth's arguments regarding the unacceptability of AI control by independent entities capable of deactivating systems or interfering in military operations at any moment. The court pointed out that such risks pose a real threat to the state's defense capability. At the same time, the Washington court's ruling has not yet entered into legal force, as Anthropic's legal team retains the option to petition for a rehearing by an en banc panel or appeal to the U.S. Supreme Court.
