Whether the proposed nationwide class satisfied Rule 23(a)(2)’s commonality requirement.
Holding
No. The plaintiffs failed to show a common question capable of generating a common answer central to all class members’ Title VII claims.
Reasoning
Rule 23(a)(2) requires more than a shared legal label or a list of questions phrased at a high level of generality. The class members must share a common contention whose truth or falsity can resolve a central issue for every member “in one stroke.” Because a Title VII claim ordinarily turns on why a particular employment decision was made, plaintiffs seeking to litigate millions of pay and promotion decisions together needed a factual and legal “glue” linking the reasons for those decisions.
A certification court must conduct a rigorous analysis and may need to examine merits-related evidence when that evidence bears on Rule 23’s requirements. Rule 23 is not merely a pleading standard; the party seeking certification bears the burden to prove actual compliance with its prerequisites.
Wal-Mart’s official policy forbade sex discrimination. The plaintiffs therefore needed significant proof that the company nevertheless operated under a general policy of discrimination, or that it used a common biased employment practice affecting the class. Their sociological expert did not provide that proof: he testified only that Wal-Mart’s culture was vulnerable to gender bias and could not say how frequently stereotypes actually influenced employment decisions.
The only companywide policy convincingly shown was Wal-Mart’s delegation of discretionary pay and promotion decisions to local managers. But a policy of local discretion is not itself a uniform discriminatory practice; it is a policy against uniform decisionmaking. Different managers could use different criteria, make decisions for different lawful reasons, or, in some instances, discriminate. Showing that one manager exercised discretion unlawfully would not establish that another did so.
The plaintiffs’ statistical evidence did not bridge that gap. Regional and nationwide disparities could not establish a uniform pattern at every one of Wal-Mart’s thousands of stores, and the evidence did not identify a specific common employment practice beyond delegated discretion. Likewise, approximately 120 anecdotes drawn from a class of 1.5 million women and a limited number of stores were too sparse and geographically concentrated to demonstrate a companywide policy of discrimination.
