The doctrine of judicial precedent, or stare decisis, is a cornerstone of the English legal system, ensuring that the law is applied consistently and predictably. A key element of this doctrine is the rigid rule that the Court of Appeal is, with limited exceptions, bound by its own previous decisions. This principle promotes certainty but has been criticised for potentially perpetuating incorrect or outdated law, forcing costly appeals to the Supreme Court. This essay will discuss the arguments for and against granting the Court of Appeal greater freedom to depart from its own precedent. It will argue that while the certainty provided by the current rule is vital, a modest increase in flexibility could improve the administration of justice without unduly harming the legal system’s stability.
The current position was definitively established in Young v Bristol Aeroplane Co Ltd [1944] KB 718. In this case, the Court of Appeal held that it was bound to follow its own previous decisions, as well as those of courts of co-ordinate jurisdiction. Lord Greene MR laid out three exceptions to this rule. The Court of Appeal is not bound if: (1) there are two conflicting decisions of its own, in which case it must decide which to follow; (2) its own previous decision has been implicitly overruled by a later decision of the Supreme Court (or the House of Lords before it); or (3) the decision was made per incuriam, meaning it was made in ignorance of a relevant statutory provision or binding precedent (Slapper and Kelly, 2017). The per incuriam exception is interpreted very narrowly, as seen in Morelle Ltd v Wakeling [1955] 2 QB 379, making it difficult to invoke successfully. The Criminal Division of the Court of Appeal operates with slightly more flexibility, given that "the liberty of the subject is at stake" (R v Taylor [1950] 2 KB 368).
The primary argument for retaining the strict rule in Young is the need for legal certainty. The doctrine of precedent ensures that similar cases are treated in a similar way, promoting fairness and allowing lawyers to advise their clients on the likely outcome of a case with a degree of confidence. This predictability is essential for both individuals and businesses. Furthermore, granting the Court of Appeal the power to freely depart from its own decisions could undermine the hierarchical structure of the English courts. The Supreme Court is the apex court, and its role, under the 1966 Practice Statement, is to develop the law for the entire country. If the Court of Appeal, which often sits in different divisions, were able to create conflicting lines of authority by choosing when to follow its own precedents, it could lead to significant legal confusion and uncertainty. This was the view of the House of Lords in Davis v Johnson [1979] AC 264, where it strongly rebuked Lord Denning’s attempt to claim a wider power for the Court of Appeal to depart from its past decisions, reaffirming the importance of certainty and the court’s hierarchical role.
Conversely, there are compelling arguments for greater flexibility. The main criticism of the current rule is that it can perpetuate injustice. If a previous Court of Appeal decision is widely considered to be wrong, but does not fall into one of the narrow Young exceptions, the parties in a later case are bound by it. Their only recourse is a further, often prohibitively expensive and time-consuming, appeal to the Supreme Court. For many litigants, the Court of Appeal is their final court in practice, as they may lack the funds or legal grounds for a further appeal. Allowing the court to correct its own clear errors would therefore provide a more accessible and efficient route to justice (Harris, 2002). This would also relieve some of the caseload pressure on the Supreme Court, allowing it to focus on cases of the greatest public and constitutional importance.
In conclusion, the debate over the Court of Appeal’s adherence to its own precedent involves a fundamental conflict between the values of certainty and flexibility. The strict rule in Young v Bristol Aeroplane Co Ltd provides a stable and predictable legal framework, which is crucial for the rule of law. However, its rigidity can lead to individual injustices and procedural inefficiency. To grant the Court of Appeal complete freedom to depart from its decisions would be a radical step that could disrupt the judicial hierarchy and create widespread legal uncertainty. A more moderate reform, perhaps a slight widening of the per incuriam rule or the introduction of a new, tightly controlled exception for cases of clear and acknowledged error, could strike a better balance. This would allow the court to correct manifest injustices without dismantling the valuable certainty that the doctrine of precedent provides.
