Ohio v. EPA, No. 22-1081 (D.C. Cir. 2024)
Annotate this Case
The case involves a challenge to a decision by the Environmental Protection Agency (EPA) to reinstate a waiver granted to California under the Clean Air Act. The waiver allows California to set its own standards for automobile emissions, which are stricter than federal standards. The petitioners, a group of states and fuel industry entities, argued that the EPA's decision was not authorized under the Clean Air Act and violated a constitutional requirement that the federal government treat states equally in terms of their sovereign authority.
The lower courts had upheld the EPA's decision, finding that the petitioners lacked standing to challenge the decision. The petitioners appealed to the United States Court of Appeals for the District of Columbia Circuit.
The Court of Appeals affirmed the lower courts' decisions. The court found that the fuel industry petitioners lacked standing to raise their statutory claim, and that the state petitioners lacked standing to raise their preemption claim, because neither group had demonstrated that their claimed injuries would be redressed by a favorable decision by the court. The court also rejected the state petitioners' constitutional claim on the merits, holding that the EPA's decision did not violate the constitutional requirement of equal sovereignty among the states.
