"Supreme Court Rebuffs Trump Admin Bids To Pause EPA Cases"

"The Clean Air Act battles are expected to be argued later this term."

"In a setback for the Trump administration, the Supreme Court has rejected requests to freeze proceedings in a set of pending cases, including one involving California’s long-standing authority to set strict tailpipe emissions for vehicles.

The court, without elaborating, said Thursday it would deny the acting solicitor general’s request to pump the brakes on Diamond Alternative Energy v. EPA, as well as other cases that center on jurisdiction over Clean Air Act litigation.

The challenge to California’s Clean Air Act waiver is still in the briefing stage. Briefs for the government are due Feb. 26."
