United States Supreme Court

In a suit brought by 23 States challenging the Environmental Protection Agency's regulation of power-plant emissions under the Clean Air Act, 42 U.S.C. section 7412, the D.C. Circuit's judgment upholding the EPA's refusal to consider costs in its decision to regulate is reversed where the EPA interpreted section 7412(n)(1)(A) unreasonably when it deemed cost irrelevant to the decision to regulate power plants.
