Request for 11-Judge Review Could Set Stage for Supreme Court Challenge
In a significant move within the realm of artificial intelligence, Anthropic, a prominent AI lab, has officially filed an appeal against a decision made by the U.S. Department of Defense that resulted in the company’s blacklisting. This legal push underscores Anthropic’s stance that the implications of this case extend far beyond its immediate context, prompting the lab to request a hearing from the entire U.S. Court of Appeals for the District of Columbia Circuit. The argument is that such a case is of “exceptional importance,” warranting a review by all eleven judges of the court.
This request for an en banc hearing—where all judges of the circuit court would rehear the case—represents a common stage in the appeals process, which often precedes elevating a case to the Supreme Court. Anthropic seeks to ensure that the full spectrum of judicial perspectives is considered before potentially taking their fight to the highest court in the land.
Earlier in September, a three-judge panel of the appeals court had issued a 2-1 ruling against Anthropic, asserting that the Pentagon had accurately followed the Federal Acquisition Supply Chain Security Act (FASCSA) in labeling the AI firm as a “supply-chain risk.” The majority opinion, articulated by Judge Gregory Katsas, expressed concerns about whether Anthropic might manipulate its Claude AI models, which led to the controversial decision.
The blacklisting by Defense Secretary Pete Hegseth occurred after negotiations between the department and Anthropic soured, primarily due to Anthropic’s refusal to permit its Claude models to be employed in fully autonomous lethal weapon systems or for mass domestic surveillance.
Anthropic’s legal representatives have stressed that if the ruling from the earlier panel is upheld, it would govern all future interpretations of FASCSA provisions. They argue that such a precedent would require contractors to concede to government demands, fundamentally altering the landscape for AI firms and potentially stifling innovation and competition within the defense sector.
The implications of the court’s ruling are positioned as “immediate and far-reaching,” transcending the defense sector. In the appeal, Anthropic has suggested that the recent decision deviates from previous cases addressed by the Supreme Court, positioning itself as a critical player in a legal narrative that could redefine the powers and limitations placed upon government contracts.
In the event that the D.C. court ultimately denies the en banc rehearing, Anthropic retains the option to escalate its arguments to the Supreme Court. However, the judicial body is notoriously selective, typically agreeing to examine only 1% to 2% of all petitions submitted.
Opinions regarding the strategic nature of Anthropic’s appeal have been shared by experts in the field. Kathleen Farley, who leads litigation at the Chamber of Progress, a center-left industry group, remarked that Anthropic’s move appears to be calculated to bolster the likelihood of a Supreme Court review. She noted that petitioning for an en banc rehearing is part of standard procedure and may also serve to enhance the chances of the Supreme Court granting further review, especially if dissenting opinions emerge from circuit court judges advocating for an en banc hearing.
It is worth noting that the ruling from the D.C. Circuit diverges sharply from an earlier ruling from the U.S. District Court for the Northern District of California, which had previously sided with Anthropic. That court had concluded that the Trump administration’s actions against the firm represented unlawful retaliation, violating First Amendment rights—an essential precedent that highlights the contentious nature of this dispute.
This ongoing legal battle signifies a pivotal moment within the interaction of government policy and technological innovation, raising fundamental questions about the future of artificial intelligence in defense applications and the overarching principles governing vendor relationships with the state.
