If a federal discrimination case was dismissed without prejudice, is new info a reason for reopening the case.?

A federal discrimination case was dismissed because of mistakes by the attorney, who incidentally had limited knowledge and not enough to fight with. The new evidence comes from an EEOC case that was issued a right to sue letter. I heard that new evidence was a reason to get a case reopened.If a federal discrimination case was dismissed without prejudice, is new info a reason for reopening the case.?
