Comer v. Murphy Oil U.S.A.   (5th Circuit)

Whether global warming lawsuit is a political question

The NAM and other organizations supported an appeal of an adverse decision by the U.S. Court of Appeals for the Fifth Circuit in a global warming public nuisance case. The plaintiffs, Mississippi residents and property owners, alleged that the emissions from more than 150 energy and manufacturing companies increased global warming and contributed to the severity of damages resulting from Hurricane Katrina. Our brief in support of the appeal argued that the plaintiffs' theory of liability would dramatically expand tort law beyond anything ever recognized because of the tenuous link between the alleged conduct and the alleged harm. In addition, this case involves a complex regulatory matter requiring the balancing of economic, environmental and international interests, and is constitutionally the domain of the political branches of government, not the courts.

The trial court had dismissed the case on these grounds, but a three-judge panel of the Fifth Circuit reversed, allowing the case to proceed. The NAM and the defendants wanted all the judges of the Fifth Circuit to review this ruling. That court did agree to review the 3-judge ruling, and arguments were scheduled for May 24, 2010.

On May 10, the NAM filed an additional brief arguing to a larger group of judges that the goal of this lawsuit is less to obtain compensation than to achieve the regulation of greenhouse gas emissions through litigation. We described how plaintiffs have tried to define a "nuisance" broadly to encompass the kind of claims that have largely been rejected by other courts. In addition, these kinds of political questions should be handled as a public policy debate, not as an adversarial proceeding in court.

Subsequently, the court announced that another judge had been recused from the case, destroying the quorum. On May 28, the court dismissed the appeal, and since it had previously vacated the 3-judge panel's ruling, the trial court's decision dismissing the lawsuit stands. This very unusual procedural development means that the appellate ruling that the NAM opposed was nullified without a formal opinion from a majority of the judges. The case was appealed to the Supreme Court, which declined to review it.

The plaintiffs later filed a similar suit, but the district court dismissed it because the claims had already been dismissed in the first case. In addition, the judge found that the parties had no standing to sue, since they cannot show a sufficient connection between the defendants' emissions and the plaintiffs' property damage. The court also found the claims non-justiciable political questions that have no "judicially discoverable and manageable standards for resolving" them, and because these policy determinations are entrusted to the EPA.
