Dukes: Common Answers, Local Discretion, and the Wrong Class Route for Individualized Backpay

Wal-Mart Stores, Inc. v. Dukes, 564 U.S. 338 (2011), contains two distinct class-certification holdings. A majority found the proposed nationwide class lacked the required commonality on the evidence presented. The Court also held that the individualized backpay claims could not be certified under Rule 23(b)(2). Combining those holdings into a general ban on employment classes obscures both.

The official opinion reversed the Ninth Circuit's judgment affirming certification. The commonality analysis divided the Justices; the treatment of the individualized monetary claims was unanimous. Reporter-page citations below identify the respective parts.

Their claims must depend upon a common contention

564 U.S. at 350 (excerpt).

The proposed class spanned many discretionary decisions

The plaintiffs proposed a class of roughly 1.5 million female employees and challenged pay and promotion practices across Wal-Mart's operations. Local managers exercised substantial discretion. The plaintiffs offered statistical evidence, employee accounts, and social-framework testimony to connect those decisions to an alleged companywide pattern. See 564 U.S. at 342–347.

The critical question was how the asserted discrimination operated across that breadth. Sharing an employer and a protected characteristic did not alone show that a common contention would resolve an issue central to each class member's claim. The scope of the proposed class magnified the need for evidence connecting local decisions.

Commonality required a contention capable of a common answer

At 564 U.S. at 349–352, the majority explained that Rule 23(a)(2) requires more than questions stated at a high level of generality. The truth or falsity of the common contention must resolve a central issue in one stroke. The required rigorous analysis may overlap with merits issues when the evidence of a common practice is itself central to the asserted liability.

This does not authorize deciding every merits question at certification. It means a court cannot avoid the proof required for Rule 23 simply because that proof also bears on the claim. A proposed class must identify the shared mechanism and explain how common evidence can answer the material question it presents.

Discretion was not categorically immune from a class claim

The majority found the showing insufficient to connect the challenged local discretion to a general discriminatory policy. Its discussion of statistical, anecdotal, and expert evidence appears at 564 U.S. at 352–360. A policy of allowing discretion did not, on that record, supply the common direction necessary for the proposed class.

The holding should not be stated as “discretion can never be challenged on a class basis.” A shared direction governing how discretion is exercised can pose a different case. The evidentiary gap in Dukes concerned the connection between the practices alleged and the classwide answer sought. Nor should commonality be confused with the separate predominance inquiry under Rule 23(b)(3).

Rule 23(b)(2) did not fit individualized backpay

The Court's separate remedy analysis focused on Rule 23(b)(2), which addresses conduct warranting injunctive or declaratory relief for the class as a whole. The provision's indivisible-relief structure did not accommodate the individualized backpay claims presented. See 564 U.S. at 360–365.

Rule 23(b)(3) supplies additional safeguards for monetary class claims, including predominance, superiority, notice, and opt-out rights. A plaintiff cannot avoid those protections merely by attaching a request for an injunction to claims requiring individual monetary determinations. The Court left open the broader question of whether some incidental monetary relief could ever fit (b)(2); its holding concerned the claims before it.

The rejected trial-by-formula proposal implicated substantive defenses

At 564 U.S. at 365–367, the Court rejected a proposed approach that would determine outcomes for a sample and extrapolate to the class while preventing Wal-Mart from presenting individual statutory defenses. Rule 23 could not abridge those substantive rights through a procedural shortcut.

The point is not that every statistical technique is forbidden. It is that the proposed method must respect the elements, defenses, and individual determinations required by the substantive law. A class plan needs to explain how claims will be adjudicated, not merely how an aggregate number might be estimated.

The dissent illuminates the dispute without changing the holding

The partial dissent disagreed with the majority's commonality analysis and would have allowed further consideration of a different certification route. See 564 U.S. at 367–378. It did not make the rejected Rule 23(b)(2) backpay structure valid. Distinguishing the opinions prevents a citation to a dissenting argument from being presented as the Court's rule.

For another employment case, the practical sequence is to define the challenged practice, identify the common answer, match the evidence to the proposed class, and choose a rule suited to the requested relief. Our cross-location evidence guide applies that sequence to records collection. A failed nationwide class does not decide the merits of every individual's discrimination claim or the viability of every narrower class.

Practical implications: Preserve individual claim records while counsel evaluates commonality, the proper class route, and the requested remedy.

Frequently asked questions

What were the two principal holdings?

The proposed class lacked commonality on the evidence presented, and the individualized backpay claims could not proceed under Rule 23(b)(2).

Did the Court decide that no monetary relief can ever fit Rule 23(b)(2)?

It rejected the individualized claims presented and left open the broader question of some incidental monetary relief.

Why was sampling a problem in this proposed plan?

The rejected plan would have deprived the defendant of individual statutory defenses. A procedural class device cannot abridge substantive rights.
