AG Bonta Files a Motion for a Preliminary Injunction to Block the Trump Administration’s Unlawful Reclassification of Clean Air Act Waivers

Published Date: Jun 25, 2026

AG Bonta, Governor Newsom, and the California Air Resources Board (CARB) today filed a motion for a preliminary injunction to block the Trump Administration’s recent actions targeting four Clean Air Act preemption waivers previously granted to California.  The U.S. Environmental Protection Agency (EPA) illegally reclassified these waivers as though they are “rules” subject to Congressional disapproval and sent them to Congress in an apparent pursuit of such disapproval.

“The Trump Administration is resorting to a familiar illegal playbook. Its continuous, outright assault on California’s waivers is blatantly politically motivated, and California won’t stand for this. We’re asking the court to stop the Administration’s latest attack on our waivers that threatens both public health and good, green jobs that bolster our economy.” -AG Bonta
