1. In Wal-Mart v. Dukes, the Supreme Court decided that the group of 1.5 million female employees could not proceed together as a single class action lawsuit which meant that each woman would have to bring their case individually rather than as part of one large class-action. The Court justified its decision based on the legal requirement of “commonality” which means that everyone  must have  common problems and can be handled collectively in a single lawsuit. It was argued that the women’s experiences were too disparate because they worked in different stores under different managers and were affected by different decisions indicating there was no accurate policy or single decision-maker accountable for all the alleged discrimination.
