law: In addition to the more general meaning, prejudice has a very specific meaning when seen in the form without prejudice or with prejudice. Without prejudice means that a lawsuit or proceeding ended without legal conclusions. In a civil case, that means a case could be re-filed in the future as though the proceeding never happened. With prejudice means the lawsuit or proceeding was dismissed and cannot be re-filed by the plaintiff with the same claim.
