AI giant Anthropic has scored a major legal victory after the federal judge temporarily blocked the Pentagon from labelling the company a “national security risk.” According to a report by Business Insider, US district judge Rita Lin has granted Anthropic’s request for a preliminary injunction, halting both the Presidential Directive ordering federal agencies to stop using Anthropic’s technology and defence secretary Pete Hegseth’s designation of the company as a “supply chain risk.” The ruling means the designation cannot take effect while the injunction is in place, allowing Anthropic to continue doing business with defense contractors.Judge Lin criticized the government’s actions, saying they looked like “an attempt to cripple Anthropic” rather than a straightforward decision to stop using its AI tool Claude. She noted that one amicus brief described the Pentagon’s move as “attempted corporate murder.”

Anthropic welcomes the decision

In a statement, Anthropic said: “We’re grateful to the court for moving swiftly, and pleased they agree Anthropic is likely to succeed on the merits. While this case was necessary to protect Anthropic, our customers, and our partners, our focus remains on working productively with the government to ensure all Americans benefit from safe, reliable AI.”

Pentagon’s arguments against Anthropic

As per the BI report, deputy assistant attorney general Eric Hamilton argued in the county that Pentagon has raised questions of Anthropic’s “reliability and trustworthiness,” warning the company could manipulate its AI models or restrict access. Defense officials have accused Anthropic of putting “Silicon Valley ideology above American lives.” US President Donald Trump also attacked the company on Truth Social, calling it a “WOKE COMPANY” and claiming its actions put national security in jeopardy.

“Good afternoon to both of you. Yesterday, I disclosed a list of questions that I asked counsel to be prepared to answer today. Before we go down that list, I thought it might be helpful for the attorneys to hear kind of a general overview of my tentative thoughts on the case so far, and you’re welcome to sit down for that if you’d like. Then, I’ll invite you back up to address the questions.I will say that I do think this case touches on an important debate. On the one hand, Anthropic is saying that its AI product, Claude, is not safe to use for autonomous lethal weapons and domestic mass surveillance. Anthropic’s position is that if the government wants to use its technology, the government has to agree not to use it for those purposes. On the other hand, the Department of War is saying that military commanders have to decide what is safe for its AI to do, not a private company.It’s a fascinating public policy debate, and it’s not my role to decide who’s right in that debate — that is Secretary Hegseth’s call. The Department of War decides what AI product it wants to use and buy. And everyone, including Anthropic, agrees that the Department of War is free to stop using Claude and look for a more permissive AI vendor.I don’t see that as being what this case is about. I see the question in this case as being a very different one, which is, whether the government violated the law when it went beyond that.After Anthropic went public with this contracting dispute, defendants seemed to have a pretty big reaction to that. They took three actions that are the subject of this lawsuit. First, the president announced that every federal agency, not just the Department of War, would immediately ban Anthropic from ever having another government contract. So, that would include the National Endowment for the Arts using Claude to design its website — not allowed.Second, Secretary Hegseth announced that anyone who wants to do business with the US military has to sever their commercial relationship with Anthropic. So, if a company uses Claude to have a customer service chatbot, now they can’t do any defense work.Third, the Department of War designated Anthropic as a ‘supply chain risk.’ That label applies to adversaries of the US government who may sabotage its technology systems. It’s typically directed at foreign intelligence, terrorists, or other hostile actors.What is troubling to me about these three actions is that they don’t really seem to be tailored to the stated national security concern. If the worry is about the integrity of the operational chain of command, DOW could just stop using Claude. It looks like defendants went further than that because they were trying to punish Anthropic.One of the amicus briefs used the term ‘attempted corporate murder.’ I don’t know if it’s murder, but it looks like an attempt to cripple Anthropic. And specifically, my concern is whether Anthropic is being punished for criticizing the government’s contracting position in the press.Defendants say they were doing this because Anthropic’s ‘sanctimonious rhetoric’ was an attempt to ‘strong-arm the government.’ DOW’s records say that it designated Anthropic as a supply chain risk because it was ‘hostile in the press.’ So it looks like DOW’s punishing Anthropic for trying to bring public scrutiny to this contracting dispute, which, of course, would be a violation of the First Amendment. So I have a lot of concern about that, and I would like to hear more from the government about that.I also have a lot of questions about — one, whether Congress gave defendants the authority to do this in the first place, and two, whether defendants violated Anthropic’s due process rights by not giving them notice and an opportunity to respond.The questions I put out yesterday really go more to those latter two topics. So, I want to start going through those questions, but I will just say that at the end of the questions, I’ll give both parties an opportunity to address the court. You can give me your reaction to the tentative thoughts that I gave you, and you can also just let me know anything else you think is important that I know about the case before I take it under submission.So let me just invite counsel back up to the podiums, and we’ll just go through the questions.”
