The Supreme Court, not surprisingly, granted Wal-Mart’s petition for certiorari today, agreeing to review the 500,000-member class certification decision from the Ninth Circuit, which had held 6-5 that the class could be certified, even though, as Judge Kozinski wrote, the class members

held a multitude of jobs, at different levels of Wal-Mart’s hierarchy, for variable lengths of time, in 3,400 stores, sprinkled across 50 states, with a kaleidoscope of supervisors — male and female — subject to a variety of regional policies that all differed depending on each class member’s job, location and period of employment.
