A little over a year ago, the U.S. Supreme Court rejected a class action suit filed by 1.5 million women against their employer, Wal-Mart. The 5-4 decision in Wal-Mart v. Dukes ruled that the employees failed to prove a common, company-wide practice of discrimination to maintain their class claim. Although surely a monumental decision, its long-term effects are still unclear.

Ballard Spahr partner Steven Suflas, who focuses his practice on labor and employment, analyzed the results. One immediate effect, he says, was that a lot of employers with pending class-action suits filed reconsideration motions and, overall, were successful.

Despite successful reconsideration motions, the Dukes ruling hasn’t quelled employers’ worries in the long run. The number of class-action suits hasn’t decreased but, rather, the nature of the suit filed has changed.

The plaintiffs are also filing cases in different venues, such as state courts, but it is not clear if they will have more success there. “It’s hard to say if it’s working for employees to file in state courts, as it’s only been one year,” Mr. Suflas says, “but it’ll be interesting to see what happens in the Dukes cases themselves moving forward.”
