The Justices actually agreed that the class – several hundred thousand women who claimed Wal-Mart discriminated against them because of their sex – was too big. That their claims were not all similar enough. The four liberal Justices did differ with the five conservatives in accepting the evidence that there was widespread sexual discrimination at Wal-Mart. But that issue really wasn’t reached.
The women will have to decide if they want to pursue their cases in smaller groups, or individually. This is a big relief for Wal-Mart.
