Quick Summary
Caroline Behrend and others (plaintiffs) sued Comcast Corporation (defendant), alleging antitrust violations in Philadelphia’s cable market. The dispute centered on whether damages could be calculated for the entire class using one common methodology.
The Supreme Court ruled that the class was improperly certified because the plaintiffs’ damages model did not adequately measure damages specific to their single accepted theory of antitrust impact.
Facts of the Case
Caroline Behrend and other plaintiffs (plaintiffs) initiated a class-action lawsuit against Comcast Corporation and its subsidiaries (defendants), alleging violations of federal antitrust laws. The plaintiffs accused Comcast of attempting to monopolize the cable market in Philadelphia through a series of transactions with other cable providers that led to less competition and higher prices for consumers.
The plaintiffs sought to certify a class under Federal Rule of Civil Procedure 23(b)(3), proposing four theories of antitrust impact and presenting an expert’s damages model. The district court accepted one theory, the overbuilder theory, which suggested Comcast’s actions deterred competitors from entering the market.
The plaintiffs’ expert designed a regression model to estimate damages, which the district court found could be applied on a classwide basis. Comcast appealed, challenging the sufficiency of the damages model in representing the class’s claims. The appeals court affirmed the district court’s decision, leading to Comcast’s petition for certiorari to the Supreme Court.

I.R.A.C. Format
Issue
Whether the class action was improperly certified under Federal Rule of Civil Procedure 23(b)(3) due to the plaintiffs’ failure to establish that damages could be measured on a classwide basis using a common methodology.
Rule of Law
To certify a class action under Rule 23(b)(3), plaintiffs must demonstrate that legal or factual questions common to class members predominate over individual questions and that damages are measurable on a classwide basis through a common methodology.
Reasoning and Analysis
The Supreme Court conducted a rigorous analysis to determine if the requirements for class certification were met. The Court noted that at the certification stage, a damages model must measure only those damages attributable to the theory of antitrust impact accepted for class-action treatment.
The plaintiffs’ model, which did not isolate damages linked to overbuilder deterrence, could not establish that damages were uniform across the class. Consequently, questions of individual damages calculations would overshadow common questions, failing to meet the predominance requirement of Rule 23(b)(3).
The Court found that both the district court and the appeals court erred by not requiring a proper connection between the single theory of antitrust impact and the calculation of damages. This misstep led to the conclusion that the class was improperly certified, as it did not adhere to the standards set by Rule 23(b)(3).
Conclusion
The Supreme Court reversed the judgment of the Court of Appeals, holding that the class action was improperly certified under Rule 23(b)(3).
Dissenting Opinions
Justices Ginsburg and Breyer filed a dissenting opinion, in which Justices Sotomayor and Kagan joined, arguing that the case was unfit for Supreme Court review due to procedural issues and that the majority’s decision did not create new standards for class certification under Rule 23(b)(3).
Key Takeaways
- Class certification under Rule 23(b)(3) requires proof that common questions predominate over individual ones and that damages can be measured on a classwide basis.
- A damages model must align with the theory of antitrust impact that forms the basis of the plaintiffs’ claims.
- Failure to demonstrate that damages can be calculated uniformly across all class members can result in denial of class certification.
Relevant FAQs of this case
What criteria must a class action meet under Rule 23(b)(3) to be certified?
The criteria for a class action under Rule 23(b)(3) include numerosity, commonality, typicality, and adequacy of representation. Importantly, claims must predominate over any questions affecting only individual members, and class resolution must be superior to other methods for fair and efficient adjudication.
- For example: A consumer rights case where a large number of people are overcharged by a utility company in a similar manner would meet these criteria for a class action.
How should damages be calculated to ensure uniformity across all class members?
Calculation of damages for class members requires a common methodology that is capable of demonstrating the extent of damages through legally relevant metrics applicable to the whole class without significant individual variations.
- For example: In a product liability case, if a defective product caused similar harm to all consumers, a common formula could be used to calculate individual reparations based on the extent of each claimant’s use or injury.
How do courts determine whether common legal or factual questions 'predominate' in a class-action lawsuit?
Courts assess whether common questions ‘predominate’ by evaluating if the proposed class members have been harmed in similar ways by the same legal or factual issues, and if these shared questions are more substantial than the issues that pertain only to individual class members.
- For example: In a labor law case where employees were systematically denied overtime pay due to an employer’s policy, this common illegal practice would likely predominate over individual differences in work hours or roles.
