A United States federal judge on Thursday blocked the Pentagon from enforcing its controversial blacklisting of artificial intelligence company Anthropic. District Judge Rita Lin issued a detailed ruling declaring the Department of Defense designation illegal and baseless. The legal conflict erupted after Defense Secretary Pete Hegseth labeled the Claude chatbot maker a national security supply chain risk. This unprecedented procurement action followed Anthropic refusing military demands to utilize its software for fully autonomous weapons systems and domestic surveillance operations. The court found that the government violated constitutional free speech protections by retaliating against the firm for public criticism. Furthermore, the judge ruled that officials breached due process rights by denying the company a proper administrative hearing. While the court vacated the supply chain risk designation and ordered directives revoked, the judge stayed enforcement for seven days to allow potential government appeals. Meanwhile, a separate legal challenge concerning civilian contracts remains.
