DOJ Directly Counters Anthropic’s First Amendment Argument — 40-Page Filing (3/17, Key This Week)

The Department of Justice filed a 40-page brief urging the California federal court to reject Anthropic’s preliminary injunction request. Legal battle reaches peak intensity ahead of the 3/24 hearing.

DOJ’s core arguments:

• “Conduct, not speech”: Anthropic’s refusal to accept government contract terms is conduct, not expression protected by the First Amendment
• “Same result even assuming retaliation”: Even if a retaliatory motive existed, the government would have taken the same actions based solely on legitimate national security concerns
• “Terms of service became unacceptable”: Anthropic’s terms became unacceptable to the executive branch after the company insisted on restrictions regarding autonomous weapons and mass surveillance

Pentagon CTO “Pretty Confident” About Life After Anthropic (3/18)

Pentagon Under Secretary (CTO) Emil Michael publicly expressed confidence in replacing Anthropic.

Key quotes:

• “Already deployed OpenAI”: “We’ve already deployed OpenAI in the last few weeks, and we’re going to deploy the others here, [starting] with Gemini”
• “Workflows are very similar”: Claims transition disruption will be minimal due to similar workflows across competing models
• “Single provider was the problem”: “One primary provider doesn’t work for the Department of War”
• Model strengths acknowledged: Claude excels at coding, xAI handles real-time content, Gemini benefits from YouTube integration
• 180-day transition deadline: Defense vendors must certify they are not using Claude in DoD work

• No backdoor or kill switch: Thiyagu Ramasamy declared under oath: “Anthropic has never had the ability to cause Claude to stop working, alter its functionality, shut off access”
• 3/24 hearing D-2: Preliminary injunction hearing before Judge Rita Lin in 2 days
