Dukes v. Wal-Mart Stores, Inc.

Dukes v. Wal-Mart Stores, Inc. was a landmark class-action lawsuit where female employees alleged that Wal-Mart’s pay and promotion policies discriminated against women. The plaintiffs argued that the company's practices resulted in widespread gender discrimination across many stores. The case raised important questions about whether large groups of employees could sue as a class. In 2011, the Supreme Court ruled that the women’s lawsuit did not meet the legal standards for class certification because they couldn’t demonstrate uniform discrimination across all stores, emphasizing the need for plaintiff groups to show commonality in their claims.
