"A coalition of Republican attorneys general on Wednesday asked the Supreme Court to stay the federal “Good Neighbor” interstate smog rule while they appeal a lower court ruling.
The plaintiffs, led by Dave Yost of Ohio, asked the high court to pause the rule, which regulates the flow of air pollution across state lines from 24 upwind states, during their appeal of an unfavorable opinion by the U.S. Court of Appeals for the District of Columbia Circuit.
“The Court should stay application of this federal plan while many parties — including Ohio, Indiana and West Virginia — challenge this plan in the D.C. Circuit. The challengers are likely to succeed on their claims under the Administrative Procedure Act,” the plaintiffs wrote."
