Wal-Mart Stores, Inc. v. Dukes
The Supreme Court threw out the certification of a massive class action brought by female Wal-Mart employees who claimed the company's pay and promotion practices discriminated against women nationwide.
The Court ruled the employees had not shown a common question that could be answered the same way for everyone in the class, and separately held that their backpay claims could not be certified under the part of the class-action rule meant for injunctions rather than money damages. The decision made it substantially harder to bring huge, company-wide discrimination class actions.
“Without some glue holding the alleged reasons for all those decisions together, it will be impossible to say that examination of all the class members’ claims for relief will produce a common answer to the crucial question why was I disfavored.”
Explains why the plaintiffs needed unifying proof to certify a companywide discrimination class.
How it got here: A federal district court certified the nationwide class, and the Ninth Circuit largely affirmed; Wal-Mart asked the Supreme Court to review the certification.
The Case in Depth
What happened
Three current or former female Wal-Mart employees—Betty Dukes, Christine Kwapnoski, and Edith Arana—sued the nation's largest private employer, alleging that local managers' broad discretion over pay and promotions disproportionately favored men. They sought to represent about 1.5 million female employees nationwide, seeking injunctive and declaratory relief, punitive damages, and backpay, arguing a corporate culture allowed gender bias to infect thousands of individual employment decisions.
The question before the Court
Could roughly 1.5 million current and former female Wal-Mart employees sue the company together as one class for sex discrimination in pay and promotions?
The Court's answer
No — the Supreme Court ruled that the roughly 1.5 million female employees could not proceed as a single class, because they failed to show a common question capable of producing one classwide answer to the discrimination claim. Wal-Mart's actual companywide policy was to give local managers broad discretion, not a demonstrated practice of bias, so the "glue" needed to tie together millions of individual pay and promotion decisions was missing.
The Court also held that even if the class had cleared that bar, the workers' backpay claims were improperly certified under Rule 23(b)(2), which covers only a single injunction or declaration benefiting everyone alike. Individualized monetary claims like backpay belong instead under Rule 23(b)(3), which comes with stricter procedural protections like notice and the right to opt out.

Why it matters
Employees who believe they were discriminated against by decentralized, discretion-based decision-making at large companies will generally need more concrete, unifying proof of a company-wide policy before they can sue as one giant class. The ruling makes it harder to combine individualized backpay claims with classwide injunctive relief, pushing plaintiffs toward smaller, more targeted class actions or individual lawsuits, particularly in workplace discrimination cases.
What changes now
The class certification is undone, and the massive nationwide class action cannot proceed as structured. Employees may attempt to pursue narrower class actions—for example, limited to particular stores or regions—that can show a genuine common policy, or they may need to bring individual claims. Any backpay claims going forward would have to satisfy Rule 23(b)(3)'s tougher requirements, including notice and the right to opt out.
What this does not decide
The Court did not decide whether monetary relief of any kind can ever be certified under Rule 23(b)(2), since it found the backpay claims here were not incidental to the injunctive relief sought. It also did not rule out smaller, more targeted class actions against Wal-Mart if plaintiffs can show a genuine common discriminatory policy.
Concurrences and dissents
Dissent in part — Justice Ginsburg
“The Court gives no credence to the key dispute common to the class: whether Wal-Mart’s discretionary pay and promotion policies are discriminatory.”Ginsburg's core objection that the majority overlooked the class's shared legal question.
Justice Ginsburg agreed that the backpay claims were wrongly certified under Rule 23(b)(2), but disagreed that the class failed the commonality requirement. She argued the majority improperly imported Rule 23(b)(3)'s demanding 'predominance' analysis into the more lenient Rule 23(a)(2) commonality inquiry, and would have let the case proceed to determine whether the class could satisfy Rule 23(b)(3) on remand.
How the Court got there
The legal reasoning, step by step
- The Court applied Rule 23(a)(2)'s 'commonality' requirement, which asks whether class members share a common question capable of generating one answer that resolves an issue central to every class member's claim.
- Because Title VII claims turn on 'the reason for a particular employment decision,' the Court held that proving commonality here necessarily overlapped with the merits question of whether Wal-Mart followed a pattern or practice of discrimination.
- Drawing on General Telephone Co. of Southwest v. Falcon, a 1982 case describing how to bridge the gap between one worker's claim and an entire class's claim, the Court said plaintiffs needed 'significant proof' that Wal-Mart operated under a general policy of discrimination.
- The Court found no such proof: Wal-Mart's written policy banned sex discrimination, and the plaintiffs' sociologist could not say what percentage of employment decisions, if any, were influenced by stereotyping.
- The only company-wide practice the evidence established was Wal-Mart's policy of giving local managers broad discretion over pay and promotions, which the Court said undercuts rather than supports a claim that everyone suffered from the same discriminatory practice.
- Turning to the backpay claims, the Court held that Rule 23(b)(2) covers only claims for a single, indivisible injunction or declaration benefiting the whole class alike, so individualized monetary claims like backpay must instead meet Rule 23(b)(3)'s stricter procedural requirements.
