To answer the discussion board question, in the Wal-Mart v. Dukes case, the Supreme Court  made a decision that had centered on the idea of “commonality” which was a requirement for class-action lawsuits. The case included over 1.5 million women that had made allegations towards Wal-Mart for their discrimination of women in the workplace through the imbalance of the amount they were paid and decisions regarding their promotions. Commonality in legal terms means the use of common questions of law or fact that affected the class. To proceed with the class, the plaintiffs had to find a basis on their claims of their discrimination that could be solved collectively. In a 5-4 decision that was ruled against the plaintiffs, they decided that there wasn’t a connected link between the corporate policies in the workplace that connected the acts of discrimination to each other. The importance of the court’s decision revealed the challenges that come with facing claims of systemic discrimination under class-action lawsuits. It displays the complex process of addressing that kind of discrimination in that environment.
