SAN FRANCISCO -- It's a lawsuit that could cost Wal-Mart billions of dollars. And a federal appeals court is allowing the case to be heard.
The huge class-action lawsuit alleges gender discrimination over the way the store chain pays its female workers.
The retailer has fiercely fought the lawsuit since it was first filed in 2001.
The lawsuit alleges that Wal-Mart pays women less then men for the same jobs and that female employees receive fewer promotions and have to wait longer for those promotions than male counterparts.
