American Power Company, Inc., et al. v. Connecticut, et al., 131 S. Ct. 2527 (U.S. Sup. Ct. 2011), rev'g., 582 F.3d 309 (2nd Cir. 2009)

(federal courts do not have jurisdiction to hear federal common law nuisance claims relating to greenhouse gas emissions; authority to regulate such gases delegated to EPA and courts' job to review EPA regulations, not decide what the regulations are to be in the first place; Clean Air Act and EPA actions displaced any federal common law right to seek relief sought; CAA directs EPA to list categories of air pollution and establish emission standards; Court unanimously reverses Second Circuit opinion authored by Justice Sotomayor who took no part in the Court's opinion on review).
