The US Justice Department has filed motions to block a private lawsuit seeking to shut down a massive artificial intelligence facility in Southaven, Mississippi. The actions, taken by the Justice Department’s Environment and Natural Resources Division, side with xAI and its subsidiary, MZX Tech LLC. Private citizens brought the lawsuit, alleging that the facility’s power source violates Clean Air Act permitting requirements.

Background

However, the State of Mississippi—the government entity responsible for running the state’s permitting program—had already officially determined that no permit was required. Federal officials argue the lawsuit threatens critical infrastructure. The Southaven data center trains and develops new AI models used by both the civilian economy and the Department of War.

The private plaintiffs are seeking damages and an injunction to halt operations, which the DOJ warns would cut off critical power during an energy emergency and hinder national defense. Associate Attorney General Stanley Woodward stated, “Ultimate responsibility for enforcing federal law belongs to the Executive Branch, not private interest groups.”

Constitutional Implications

The federal intervention points to a recently issued executive order by President Donald J. Trump, titled “Promoting Advanced Artificial Intelligence Innovation and Security.” The order directs federal agencies, committees, and officials to prioritize AI development and security across the government. According to government filings, the Clean Air Act grants the federal government the authority to intervene in citizen-led lawsuits, while the US Constitution gives the president the responsibility to enforce laws and exercise enforcement discretion in the national interest.
