The doctrine of precedent, or stare decisis, forms a cornerstone of the English legal system by requiring courts to follow earlier decisions. This essay examines whether the Court of Appeal should enjoy greater latitude to depart from its own rulings. It considers the existing restrictions under the rule in Young v Bristol Aeroplane Co Ltd, weighs arguments for increased flexibility against the need for certainty, and concludes that the current framework largely preserves the balance between stability and justice.
The Current Legal Framework
The Court of Appeal is generally bound by its previous decisions. In Young v Bristol Aeroplane Co Ltd [1944] KB 718, the court identified three narrow exceptions: where two of its own decisions conflict, where a decision has been impliedly overruled by the Supreme Court (formerly the House of Lords), or where a decision was reached per incuriam. These exceptions are strictly applied, as affirmed in later cases such as Davis v Johnson [1979] AC 264, where attempts to broaden the exceptions were rejected by the House of Lords. The framework therefore maintains a clear hierarchy and promotes consistency across appellate decisions.
Arguments for Greater Freedom
Proponents argue that limited exceptions can produce injustice when earlier decisions are clearly wrong or outdated. Greater freedom would allow the Court of Appeal to correct errors without awaiting Supreme Court intervention, thereby reducing costs and delays for litigants. It could also enable incremental adaptation to social or economic changes, particularly in areas such as family or contract law where rigid precedent may stifle development. A modest expansion might mirror the Practice Statement of 1966 that permits the Supreme Court to depart from its own decisions when it appears right to do so.
Arguments Against Greater Freedom
Nevertheless, widening the scope for departure risks undermining the predictability that precedent provides. Litigants rely on established rulings to assess the strength of their claims; uncertainty could encourage speculative litigation and forum shopping. Furthermore, frequent departures might erode the hierarchical structure of the courts, blurring the distinction between the Court of Appeal and the Supreme Court. The risk of divergent decisions across different divisions of the Court of Appeal could also threaten the uniform application of law across England and Wales.
Conclusion
While the case for limited reform has merit, the potential damage to legal certainty outweighs the benefits. The existing exceptions, though narrow, already accommodate the most pressing instances of injustice. Any further relaxation should therefore be approached with caution, preserving the doctrine’s core function of ensuring consistent and foreseeable outcomes.
