In the Wal-Mart case, the Supreme Court decided that the group of women suing the company couldn’t move forward as a class-action lawsuit. The Court said the main reason was because there wasn’t enough “commonality” among all their claims. In other words, the women had different experiences and reasons for why they believed they were treated unfairly, so their situations weren’t similar enough to be handled all together in one big case. The Court explained that for a class-action lawsuit to work, everyone’s claim needs to share a common issue that ties them closely together—kind of like how all members of a team have to be playing the same game, not just wearing the same jersey.
