Nearly 150 Retired Judges Join Anthropic’s Legal Battle Against the Pentagon Over AI Policy

In a surprising display of bipartisan legal solidarity, almost 150 former federal and state judges have signed an amicus curiae brief supporting the artificial‑intelligence startup Anthropic in its lawsuit against the U.S. Department of Defense. The brief, filed with the U.S. Court of Appeals for the D.C. Circuit, argues that the Pentagon’s current AI policy violates constitutional limits and threatens the nation’s technological edge. The move has attracted attention from lawmakers, tech advocates, and defense analysts alike, raising questions about the future of AI governance in the military.

Who Is Anthropic and Why the Case Matters

Anthropic, founded in 2021 by former OpenAI researchers, positions itself as a leader in “AI safety” and “aligned intelligence.” The company’s mission is to build large language models that can be reliably controlled and that pose minimal risks to society. Anthropic’s flagship model, Claude, has already been adopted by several Fortune 500 firms for internal use.

In March, Anthropic filed a lawsuit against the Pentagon, alleging that the Department’s AI strategy—particularly its “AI‑Enabled Warfare” directive—fails to meet constitutional standards and undermines the U.S.’s competitive advantage. The company claims that the Pentagon’s approach encourages the rapid deployment of untested AI systems in combat scenarios, potentially violating the First Amendment’s protection of free speech and the Fourth Amendment’s safeguards against unreasonable searches and seizures. Anthropic also argues that the policy creates a “regulatory vacuum” that could allow the U.S. to fall behind China and other rivals in AI‑driven defense capabilities.

The Pentagon’s AI Policy and the Legal Challenge

The Department of Defense’s AI policy, released in early 2024, outlines a framework for integrating artificial intelligence into military operations. Key provisions include:

• Rapid Deployment: The directive encourages the quick fielding of AI systems in the battlefield to maintain a technological edge.
• Minimal Oversight: Oversight mechanisms are limited, with the emphasis placed on operational commanders rather than civilian review boards.
• Export Controls: The policy relaxes certain export restrictions to facilitate joint operations with allied nations.
• Ethical Guidelines: While the policy references ethical considerations, it lacks enforceable standards for AI safety and accountability.

Anthropic’s lawsuit contends that these provisions create a legal environment where AI can be deployed without adequate safety checks, potentially leading to violations of constitutional rights. The company also points to the lack of a clear, enforceable framework for AI accountability, arguing that this could result in the misuse of autonomous weapons and the erosion of civil liberties.

Judges Rally: What Their Amicus Brief Says

The amicus brief, signed by judges from across the political spectrum, emphasizes several key arguments:

• Constitutional Safeguards: The brief stresses that the First and Fourth Amendments impose limits on how the government can use AI, especially in contexts that affect free speech and privacy.
• Precedent from Civil Rights Law: The judges cite landmark cases such as Brown v. Board of Education and Roe v.
