Anthropic and DoD Face Three-Judge Appeals Panel
The hearing between Anthropic and the DoD is scheduled for Tuesday, May 19, 2026, at 9:30 a.m. ET at a federal appeals court in Washington, D.C. A three-judge panel, made up of Karen LeCraft Henderson, Gregory G. Katsas, and Neomi Rao, will hear arguments from both sides.
Each side will have only 15 minutes to present its case. This means the judges are expected to focus primarily on core legal questions rather than detailed evidence. The panel may also directly question attorneys representing both Anthropic and the Department of Defense.
A written ruling will follow after the court takes the case under advisement. After the hearing, the court will then issue a written ruling for its final decision. The outcome of the dispute could have significant implications on the AI sector.
DoD Brief Warns of National Security Risks From AI Controls
The dispute began in March 2026, when the Pentagon labeled Anthropic a supply-chain risk after the AI firm refused to provide unrestricted access to its Claude models. Anthropic challenged the label, arguing that it was not driven by genuine security concerns but was a retaliation for its refusal to weaken safety constraints on Claude.
In a court filing ahead of the upcoming hearing, the DoD argued that Anthropic could “encode limitations” into its models to prevent misuse. However, it warned that doing so could still create an “untenable national-security risk.” Officials, including Secretary Pete Hegseth, also said Anthropic had “undermined the trust required” for cooperation.
He further argued that the company-imposed restrictions could interfere with military operations. Meanwhile, Anthropic rejected these claims in their own brief.
The company noted that reliably embedding such safety limits into future models is unrealistic and does not justify blacklisting it. Its lawyers also argue that the DoD exceeded its authority and violated constitutional protections. They are now asking the court to declare the designation unlawful.
