Non-binding precedents are those that a judge listening to a given case can ignore or overrule. Generally, the decisions of lower courts are not binding on the higher courts. For instance, the House of Lords, which is the highest court in the land, is not bound by the decisions of any other court in the UK. In fact, it is not bound by its earlier precedents. Therefore, the House of Lords can overrule the decision of other lower courts and even go against its previous rulings.
