Comcast Corp. v. Behrend

by
Comcast and its subsidiaries allegedly “cluster” cable television operations within a region by swapping their systems outside the region for competitor systems inside the region. Plaintiffs filed a class-action antitrust suit, claiming that Comcast’s strategy lessens competition and leads to supra-competitive prices. The district court required them to show that the antitrust impact of the violation could be proved at trial through evidence common to the class and that damages were measurable on a classwide basis through a “common methodology.” The court accepted only one of four proposed theories of antitrust impact: that Comcast’s actions lessened competition from “overbuilders,” i.e., companies that build competing networks in areas where an incumbent cable company already operates. It certified the class, finding that the damages from overbuilder deterrence could be calculated on a classwide basis, even though plaintiffs’ expert acknowledged that his regression model did not isolate damages resulting from any one of the theories. In affirming, the Third Circuit refused to consider Comcast’s argument that the model failed to attribute damages to overbuilder deterrence because doing so would require reaching the merits of claims at the class certification stage. The Supreme Court reversed: the class action was improperly certified under Rule 23(b)(3). The Third Circuit deviated from precedent in refusing to entertain arguments against a damages model that bore on the propriety of class certification. Under the proper standard for evaluating certification, plaintiffs’ model falls far short of establishing that damages can be measured classwide. The figure plaintiffs’ expert used was calculated assuming the validity of all four theories of antitrust impact initially advanced. Because the model cannot bridge the differences between supra-competitive prices in general and supra¬competitive prices attributable to overbuilder deterrence, Rule 23(b)(3) cannot authorize treating subscribers in the Philadelphia cluster as members of a single class.
