Is Doctrine of precedent the same as stare decisis?
Stare Decis (let the decision stand) is the basis of the doctrine of judicial precedent. Arguably they are the same thing in their fundamentals, but the doctrine of JP takes Stare Decis further by the development and evolution of procedures and rules around which the doctrine operates. For example the instances in which the Court of Appeal (Civil Division) can go agaisnt its own previous decisions (from Young v Bristol Aeroplanes I think the case is called) or the Practice Statement 1966 allowing the House of Lords to go against their own previous decisions. These exception that allow the court to go agaisnt their own decisions are part of the doctrine as well.
