In the Walmart v. Dukes case, the Supreme Court ultimately ruled that the women involved couldn’t move forward as a class. The main reason was the issue of “commonality”. In order to bring a class-action lawsuit, the group needs to show that everyone was affected in the same way by the same policy–but the court said that wasn’t the case here. Walmarts structure allowed store managers a lot of freedom when it came to pay and promotion decisions, as a result that, the discrimination claims were too different from each other to be treated as one big case. Instead of showing one clear and concise company-wide rule that hurt all the women similarly, the lawsuit was based on thousands of separate decisions made by different managers that were in different places.
