The Supreme Court decided that the women in the Wal-Mart v. Dukes case couldn’t move forward as one big class action group. Basically, the Court said there wasn’t enough “commonality” between all their situations. For a class-action lawsuit everyone has to be able to point to one shared issue or one companywide policy that caused the discrimination. In this case Wal-Mart didn’t have one big rule that treated women unfairly. Instead every store manager made their own decisions about pay and promotions. Because of that the Court said the women’s experiences were too different from each other what happened in one store might not be the same as what happened somewhere else. So the Supreme Court’s reasoning was that without a single common policy causing the problem the group didn’t meet the requirements to be considered a class. In other words the claims weren’t similar enough to link all the women together in one lawsuit.
