Introduction
This essay examines whether A.V. Dicey’s traditional perspective on parliamentary sovereignty remains relevant in the context of contemporary UK constitutional law. Dicey, a prominent 19th-century legal scholar, posited that Parliament holds supreme authority to make or repeal any law, and no body can override or set aside its legislation (Dicey, 1885). While this doctrine has long been a cornerstone of the UK’s uncodified constitution, modern developments—such as the influence of European Union (EU) law, devolution, and judicial review—raise questions about its applicability. This essay argues that although Dicey’s view provides a foundational understanding of parliamentary sovereignty, it is increasingly outdated due to evolving constitutional dynamics. The discussion will explore Dicey’s original theory, assess challenges posed by EU membership and devolution, and consider the role of the judiciary in limiting parliamentary power.
Dicey’s Doctrine of Parliamentary Sovereignty
Dicey’s articulation of parliamentary sovereignty, as outlined in his seminal work *Introduction to the Study of the Law of the Constitution*, rests on three key principles: Parliament can legislate on any matter, no Parliament can bind its successors, and no court or other body can question the validity of parliamentary enactments (Dicey, 1885). This view reflects the historical dominance of Parliament within the UK’s constitutional framework, particularly in the absence of a written constitution. Dicey’s theory was grounded in the political and legal context of his time, where parliamentary authority was rarely contested, and external influences were minimal. Indeed, his framework served as a clear expression of the UK’s constitutional hierarchy, placing Parliament at its apex. However, while this model arguably provided clarity in the 19th century, its rigidity fails to accommodate the complexities of modern governance.
Challenges from EU Membership and Brexit
One significant challenge to Dicey’s doctrine emerged with the UK’s membership in the European Union from 1973 to 2020. The European Communities Act 1972 incorporated EU law into domestic legislation, granting it primacy over conflicting UK statutes, as established in landmark cases like *Factortame Ltd v Secretary of State for Transport* (1990). This directly contradicted Dicey’s assertion that no body could override parliamentary law, as EU regulations often superseded national legislation. Even post-Brexit, the retained EU law under the European Union (Withdrawal) Act 2018 continues to influence UK legal norms, indicating a lasting impact on parliamentary sovereignty. Therefore, while Dicey’s view assumes absolute parliamentary control, the reality of international legal obligations has arguably diluted this principle, rendering his perspective outdated in a globalised legal landscape.
Devolution and the Distribution of Power
Devolution further complicates Dicey’s traditional view. The establishment of devolved legislatures in Scotland, Wales, and Northern Ireland through acts such as the Scotland Act 1998 has redistributed legislative authority within the UK. Although Parliament retains the theoretical power to repeal devolution statutes, political realities and conventions—such as the Sewel Convention—limit its ability to legislate on devolved matters without consent. This suggests a practical erosion of parliamentary supremacy, as power is shared rather than centralised. Generally, this shift indicates that Dicey’s absolute conception of sovereignty does not fully align with the UK’s contemporary constitutional arrangements, where power distribution is increasingly fragmented.
The Role of Judicial Review
Finally, the growing role of judicial review challenges Dicey’s assertion that courts cannot question parliamentary enactments. Cases such as *R (Miller) v Secretary of State for Exiting the European Union* (2017) demonstrate the judiciary’s willingness to scrutinise governmental actions and, indirectly, parliamentary decisions. While courts cannot strike down primary legislation, their interpretive role and emphasis on the rule of law impose constraints on parliamentary power. This development highlights a tension between Dicey’s view of unchecked parliamentary authority and the modern expectation of legal accountability, further suggesting that his doctrine may be outdated in addressing the judiciary’s evolving function.
Conclusion
In summary, while A.V. Dicey’s view on parliamentary sovereignty remains a foundational concept in UK constitutional law, it is increasingly outdated in light of modern developments. The influence of EU law, the practical limitations imposed by devolution, and the expanding role of judicial review all demonstrate that parliamentary supremacy is no longer absolute as Dicey envisioned. These changes reflect a more complex constitutional landscape, where power is shared and constrained by both internal and external factors. Consequently, although Dicey’s doctrine retains historical and theoretical significance, its relevance to contemporary governance is limited. Future constitutional discourse must therefore consider these evolving dynamics to fully capture the nature of sovereignty in the UK today.
