A landmark case, or landmark decision, is a court decision which is published by an appeals court or by the Supreme Court, on some matter that is serious or important to a large number of people. A landmark case, once decided, shows the usual way in which the court will rule on such issues in the future, and sometimes sets how lower courts must rule in the case of the same or a similar matter coming before them. It is sometimes referred to as a precedent setting case.
