ABSTRACT

However, a few theoretical ground rules can be established, which at least place the operation of the doctrine of precedent within a context: (1) judges at all levels of the court hierarchy must follow decisions of the higher

courts; (2) judges in the higher courts must follow previous decisions of their own courtor

that of a higher court if the case was similar, and does not fall into any allowed exceptions. It is accepted, however, that in the Court of Appeal, a more relaxed attitude can be taken in relation to criminal appeals;

(3) since a Practice Statement by the Lord Chancellor in 1966, judges in the House of Lords have the freedom to decline to follow their own previous decisions (Practice Direction (Judicial Precedent) [1966] 3 All ER 77). This freedom is exercised sparingly-but in a more relaxed way in its criminal jurisdiction than in its civil jurisdiction.
