A Miami federal judge has rejected a discrimination lawsuit by women employees of Wal-Mart Stores Inc. in the Southeast, saying they were improperly “piggybacking” on a national class action that was rejected by the U.S. Supreme Court.

But an attorney for the 11 women named in the lawsuit said he will ask U.S. District Judge Robert Scola to certify a question to the U.S. Court of Appeals for the Eleventh Circuit that could lead to reconsideration of the dismissal.
