Wal-Mart Stores issued its first response yesterday to a lawsuit that accuses it of allowing sweatshop conditions at overseas factories, saying that the labor rights group that filed the lawsuit on Tuesday had ''a history of presenting opinions as facts.''
After the group, the International Labor Rights Fund, filed the class-action suit in Los Angeles on behalf of employees for Wal-Mart contractors in China, Bangladesh, Nicaragua, Swaziland and Indonesia, Wal-Mart said it needed to study the lawsuit before responding.
