Wal-Mart Stores, Inc. v. Dukes
The Supreme Court threw out the largest employment discrimination class action ever certified, ruling that 1.5 million female Wal-Mart employees could not sue as a single class because they had not shown a common reason connecting their individual pay and promotion claims.
The Court also ruled that claims for back pay can't be bundled into this kind of class action when the money owed to each worker would require individual proof, cutting off a path some plaintiffs use to avoid the stricter rules that usually apply to group lawsuits for damages.
“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.”
Explaining why proof of a common discriminatory reason was missing across millions of pay decisions.
How it got here: A federal trial court certified the massive class action; a divided en banc Ninth Circuit largely affirmed; Wal-Mart asked the Supreme Court to review the certification.
The Case in Depth
What happened
Three current and former female Wal-Mart employees sued the retailer, claiming local managers' discretion over pay and promotions favored men, producing companywide discrimination against women. They sought to represent roughly 1.5 million female employees nationwide, seeking injunctive relief, punitive damages, and back pay, arguing that Wal-Mart's refusal to limit managers' discretion amounted to illegal discrimination under Title VII.
The question before the Court
Could 1.5 million female Wal-Mart employees sue the company together as one class over pay and promotion decisions made by thousands of different local managers?
The Court's answer
No — the Court ruled that the 1.5 million female employees could not proceed as a single class, because they failed to identify a common policy or practice tying together the millions of individual pay and promotion decisions at issue. Wal-Mart's official policy actually forbade sex discrimination, and giving local managers broad discretion was, if anything, the opposite of a uniform practice that could generate one common answer for the whole class.
The Court also ruled that the workers' back-pay claims could not be certified under the class-action rule they used, because that rule is meant for situations where a single injunction or declaration can resolve things for everyone at once — not for individualized money claims that require proof, and defenses, specific to each worker. The lower court's plan to extrapolate results from a small sample of claims was rejected because it would deny Wal-Mart the chance to fight each claim.

Why it matters
The decision makes it much harder for employees at large, decentralized companies to band together in nationwide discrimination lawsuits unless they can point to a specific company-wide policy or practice tying their claims together. It also limits when workers can seek back pay through a class action instead of proving individual damages, reshaping strategy for future workplace discrimination suits.
What changes now
The Ninth Circuit's approval of the massive class action is undone. The named plaintiffs and other Wal-Mart employees can still pursue individual discrimination claims or attempt to organize narrower class actions -- for example under the rule for money-damages classes, which comes with stricter requirements like proving common questions predominate and giving workers a chance to opt out. This ruling is final on the class-certification question and does not resolve whether any discrimination actually occurred.
What this does not decide
The Court did not decide whether Wal-Mart actually discriminated against its female employees, nor whether monetary claims can ever be certified under the injunctive-relief class rule generally. It also left open whether some kinds of 'incidental' monetary relief might still fit that rule in other cases.
Concurrences and dissents
Dissent in part — Justice Ginsburg
Justice Ginsburg agreed the back-pay claims were wrongly certified under the injunctive-relief class rule, but disagreed that the class failed the more basic 'common question' requirement. She argued the majority improperly imported the stricter money-damages class standard into that threshold test, when the trial court's finding of a common question about Wal-Mart's discretionary pay and promotion policies was reasonable and should have been given deference. She would have sent the case back to let the plaintiffs try to certify a narrower class for monetary relief.
How the Court got there
The legal reasoning, step by step
- The Court explained that to certify a class, plaintiffs must show a common question capable of producing a single, classwide answer to what caused their alleged injury -- not merely that they all suffered some violation of the same law.
- Because Title VII discrimination claims turn on the specific reason behind each employment decision, the Court said the plaintiffs needed some 'glue' connecting the reasons behind millions of separate pay and promotion decisions across thousands of stores.
- Applying the two-path framework from a prior case for bridging the gap between one worker's claim and a whole class of workers, the Court found no biased company-wide testing procedure and no 'significant proof' of a general policy of discrimination -- Wal-Mart's official policy actually forbade sex bias.
- The Court found that giving local managers broad discretion is itself the opposite of a uniform practice, and that a sociologist's testimony about corporate 'culture' could not say how often, if ever, that discretion led to biased decisions, so it fell far short of proving a common discriminatory policy.
- Turning to the back-pay claims, the Court reasoned that this type of group lawsuit is meant for situations where a single order can fix things for the whole class at once, not for money claims that require individualized proof for each worker.
- Because Wal-Mart had a right to raise individual defenses to each employee's back-pay claim, and the lower court's plan to extrapolate results from a small sample of claims would strip away that right, the Court concluded the back-pay claims could not be certified this way either.
