The U.S. District Court for the Northern District of [Mississippi](/locations/mississippi-usa.md) denied [xAI](/companies/xai.md)'s motion to dismiss the NAACP's Clean Air Act lawsuit over the gas turbine power plant in [Southaven](/locations/southaven-mississippi.md), Mississippi that supports the Colossus 2 data center, which the NAACP says operates without required permits. The court held that the plant is not a mobile source and so is not exempt from Clean Air Act permitting, and it rejected xAI's argument that citizen suits are unconstitutional. The court has yet to rule on the NAACP's motion for a preliminary injunction.
