Thus, the precedent should be deemed as ‘judicial practice rather then a doctrine’ . However, the maintenance of this practice should be described in order to discuss its’ value.
The doctrine of precedent is usually defined by the Latin phrase, which has formed the doctrine of precedent as it stands now: stare decisis et non quieta movere. That is ‘to stand by decisions and not to disturb settled matters’, in other words, previous cases may be binding for the consequent cases. The doctrine consists of some elements, the first of which is the role of the judicial hierarchy. To be more precisely, lower courts are bounded by superior courts’ decisions (vertical aspect) and decisions of courts of equal level of the hierarchy (horizontal aspect). These are binding precedents. However, persuasive precedents (decisions of lower courts, Scottish and northern Irish courts, foreign courts in common law) cannot be disregarded .
However, these general statements are not able to tell the judge whether the doctrine should be applied when two cases are similar. The further complexity here is the fact that the particular data changes from case to case and no identical cases can be founded.
