The Eighth Circuit recently issued a decision reversing class certification for lack of commonality.

In Smith v. ConocoPhillips Pipe Line Co., the Eighth Circuit considered a class action proceeding on a nuisance theory against the owner of a pipeline. The plaintiffs, who owned property near the pipeline and were suing on behalf of a class of landowners, contended that the pipeline was a nuisance because they feared environmental contamination. After the district court certified the class, the Eighth Circuit granted a petition for review and reversed.

The Eighth Circuit explained that without evidence of contamination, "the putative class fear of contamination ... is not a sufficient injury to support a claim for common law nuisance...." And the plaintiff landowners could not bridge the gap by pointing to evidence that other landowners allegedly had experienced actual contamination. The putative class, the court explained, had not experienced the requisite common interest.
