Wal-Mart v. Dukes, 564 U.S. 338 (2011), was a United States Supreme Court case in which the Court ruled that a group of roughly 1.5 million women could not be certified as a valid class of plaintiffs in a class action for employment discrimination against Walmart. Lead plaintiff Betty Dukes, a Walmart employee, and others alleged gender discrimination in pay and promotion policies and practices in Walmart stores.
The Court agreed to hear argument on whether Rule 23 (b)(2) of the Federal Rules of Civil Procedure which provides for class actions if the defendant's actions make injunctive relief appropriate, can be used to file a class action that demands monetary damages.
