D.C. Circuit Upholds DoD's Exclusion of Anthropic Claude Models
A D.C. Circuit decision upholding the Defense Department's exclusion of Anthropic's Claude models lands squarely on contractor AI-supply-chain, protest and teaming risk.
Per a Blank Rome client alert, the U.S. Court of Appeals for the D.C. Circuit issued its decision in Anthropic PBC v. U.S. Department of War on Sept. 25, upholding the Defense Department's exclusion of Anthropic's Claude models from its AI portfolio. The available source is a single law-firm alert and its text is truncated, so the panel's reasoning, the standard of review applied to the contracting officer's determinations, and the precise remedial disposition are not established here; the alert also captions the department as the "Department of War," which counsel should confirm against the docket.
Why sophisticated counsel should care: model-vendor access to defense workloads is now mediated by contracting-officer discretion over government-wide AI sourcing, not merely by competitive bidding. Prime contractors and integrators relying on a specific vendor stack face procurement-clause, teaming/subcontract, novation and price-adjustment exposure if that vendor is excluded; protest deadlines and solicitation redesign questions follow quickly. For AI vendors, the decision speaks to the government's latitude to set vendor eligibility criteria for dual-use models.
Watch for the mandate and any stay, GAO or Court of Federal Claims protest activity involving other excluded vendors, and FAR and agency implementation guidance on third-party model certification.
