Decisions of the Court of Appeal itself are binding on the High Court and the county courts.
COURT OF APPEAL (CRIMINAL DIVISION)
In principle there is no difference in the application of stare decisis in the civil and criminal divisions of the Court of Appeal. In practice, however, in addition to the Young exceptions, because a person's liberty may be at stake, precedent is not followed as rigidly in the criminal division.
In R v Taylor  2 KB 368 the Court of Appeal held that in 'questions involving the liberty of the subject' if a full court considered that 'the law has either been misapplied or misunderstood' then it must reconsider the earlier decision.
