ST. PAUL, Minn. — Contending that “Minnesota unilaterally claimed” a “regulatory authority” over greenhouse gas emissions “when it sued national energy producers in state court for alleged violations of state law,” the United States sued the state in federal court pursuant to the U.S. Constitution and the Clean Air Act (CAA) “to vindicate the supremacy of federal law in matters concerning the regulation of global greenhouse gas emissions and to redress its irreparable injuries.”
