Super-Sized WalMart Class Action Case before Supreme Court

Crowds began to form outside the US Supreme Court building at two this morning Washington time, in hopes of getting into the courtroom for arguments about the rules for class-action lawsuits. The issue involves as many as one million women who have worked for America's largest retailer. A federal appeals court has ruled that WalMart's female employees can sue as a class, and that's the issue the Supreme Court has agreed to decide. Robert Barnes covers the court for the Washington Post.
