Federal judge denies xAI bid to dismiss NAACP lawsuit over gas turbines at its Colossus data center near Memphis

What happened

A federal judge has denied a motion by xAI to dismiss a lawsuit filed on behalf of the NAACP, TechCrunch reported on October 31, 2026. The suit concerns the gas turbines that power the company's Colossus data center outside Memphis. It accuses the SpaceX-owned AI company of running those turbines without the permits it needed, and with the motion denied, the plaintiffs' claims will proceed.

The Southern Environmental Law Center brought the case for the NAACP. According to TechCrunch, the group alleges that xAI installed and ran at least 35 combustion turbines and other air pollution sources at the Colossus site. The suit says xAI never secured the required preconstruction or operating air permits for that equipment. It also accuses xAI of violating the Clean Air Act.

The arguments xAI made

Claim that the turbines are mobile

TechCrunch reported that xAI argued the turbines did not need permits because they are mobile. Judge Debra M. Brown disagreed. She wrote that the combustion turbines are not "mobile sources" under Mississippi's State Implementation Plan.

Challenge to standing and the citizen suit

The company also argued that the plaintiffs did not have standing to sue and that this type of citizen lawsuit is unconstitutional. Brown found that the plaintiffs have statutory standing under the Clean Air Act. She also concluded that the citizen suit provision does not violate Article II of the Constitution or the private nondelegation doctrine.

On the constitutional question, Brown wrote that citizen suit plaintiffs sue in their own name and seek penalties that address harm to themselves. For that reason, she wrote, "they are not exercising the federal government's executive power."

How the NAACP responded

A second denied motion this month

According to TechCrunch, the Department of Justice also filed a motion to dismiss the case, and the court denied that motion earlier in October. Abre' Connor, the NAACP's director of environmental and climate justice, said in a statement that courts have repeatedly rejected attempts by xAI and the DOJ to dismiss the case.

Connor called the latest ruling "another important victory in our effort to hold xAI accountable." She added, "Our position has been clear: xAI cannot operate gas turbines without the required permits."

The wider data center debate

TechCrunch noted that the case is moving forward as public opinion appears to have turned sharply against data centers. The outlet reported that New York recently passed a moratorium on new data centers. Other state and local governments are considering similar measures.

Company and political reactions

According to TechCrunch, the backlash led Amazon and Microsoft to promise to stop using nondisclosure agreements in their dealings with government agencies. The outlet also reported that the issue could be a significant factor in the imminent U.S. midterm elections.
