Wal-Mart Stores has asked a US federal appeals court to review a judge's order approving class-action status for a sex-discrimination lawsuit.
Wal-Mart has made a request to the US court system because it believes it is being unfairly targeted by this class-action lawsuit.
Wal-Mart would not contest the judges ruling if they though the lawsuit was fair. I think my wording may have confused the system.
