"Foes of the Trump administration's Clean Power Plan replacement have lined up to air their grievances in court.

Health groups, blue states and environmental organizations are leading the charge against EPA's Affordable Clean Energy rule in the U.S. Court of Appeals for the District of Columbia Circuit. A smattering of petitions filed by other interests round out the docket.

The ACE rule took effect Friday, closing out the deadline for lawsuits.

Challengers will argue in their consolidated case that Trump's replacement regulation skirts EPA's Clean Air Act responsibilities, undermines state clean energy mandates and threatens public health."
