On March 17, 2026, approximately 150 retired federal and state judges filed a bipartisan amicus curiae brief in the Northern District of California supporting Anthropic's challenge to the Pentagon's supply chain risk designation. The filing represented an extraordinary intervention by members of the judiciary in a dispute between a private company and the executive branch, underscoring the degree to which the legal community viewed the case as raising fundamental questions about government overreach and the rule of law.
The judges' brief raised two principal concerns. First, it argued that the supply chain risk designation — a tool created under the Federal Acquisition Supply Chain Security Act to address threats from foreign adversaries like Huawei and ZTE — was never intended to be used against domestic American companies as a form of policy enforcement. The brief warned that repurposing the designation in this manner would give the executive branch an unchecked ability to destroy any company that refused to comply with policy demands, bypassing the normal regulatory and legislative processes. Second, the judges raised alarm about government coercion of private companies, arguing that the blacklist functioned as an unconstitutional condition: comply with our demands on surveillance and autonomous weapons, or face economic destruction.
The bipartisan character of the filing was notable. The signatories included judges appointed by presidents from both parties, spanning decades of federal and state service. Several had backgrounds in national security law and emphasized that they were not questioning the government's legitimate authority to set procurement standards, but rather its use of a punitive designation to coerce a company into abandoning safety positions. CNN Business reported that legal scholars described the brief as one of the largest judicial amicus filings in a technology case in recent memory, reflecting a growing consensus within the legal establishment that the Anthropic dispute had implications far beyond the AI industry.
