Chamber of Commerce of the US, et al v. EPA, No. 09-1237 (D.C. Cir. 2011)Annotate this Case
The Chamber of Commerce and the National Automobile Dealers Association petitioned for review of a decision by the Environmental Protection Agency ("EPA") granting California a waiver from federal preemption under the Clean Air Act ("CAA"), 42 U.S.C. 7543(a). At issue was whether Article III of the Constitution granted the court jurisdiction to decide the case. The court dismissed the petition for review without reaching its merits and held that even if the EPA's decision to grant California a waiver for its emissions standards once posed an imminent threat of injury to petitioners, the agency's subsequent adoption of federal standards eliminated any independent threat that may have existed.
