Constitutional Reform Act 2005

162. This section makes provision as to the effect of decisions of the Supreme Court as judicial precedents. The essence of the provision is that a decision made by the Supreme Court under particular jurisdiction should have the same effect as a decision of the body in which the jurisdiction is currently vested (whether that is the House of Lords or the Judicial Committee of the Privy Council). So in the case of jurisdiction transferred from the House of Lords, a decision of the Supreme Court on an appeal from one jurisdiction within the United Kingdom will not have effect as a binding precedent in any other such jurisdiction, or in a subsequent appeal before the Supreme Court from another such jurisdiction. In the case of the devolution jurisdiction transferred from the Judicial Committee of the Privy Council, a decision of the Supreme Court will be binding in all legal proceedings except for subsequent proceedings before the Supreme Court itself.
