Introduction
The doctrine of parliamentary supremacy, as classically articulated by A.V. Dicey in the 19th century, posits that Parliament holds absolute legislative authority, capable of making or unmaking any law without legal limitation. However, Lord Steyn’s assertion in R (Jackson and Others) v. Attorney General [2005] UKHL 56 suggests that this traditional view is increasingly untenable in the contemporary United Kingdom. This essay explores the evolving nature of parliamentary supremacy, examining how constitutional developments, judicial attitudes, and international influences have challenged Dicey’s ‘pure and absolute’ conceptualisation. By considering key arguments and evidence, it evaluates whether this doctrine remains relevant or is, indeed, ‘out of place’ in the modern legal landscape.
The Traditional Doctrine of Parliamentary Supremacy
Dicey’s seminal work outlined parliamentary supremacy as a cornerstone of the UK’s unwritten constitution, asserting that Parliament’s legislative power is unlimited and that no court can question the validity of an Act of Parliament (Dicey, 1885). This principle, often seen as a safeguard of democratic governance, historically ensured that elected representatives could enact laws reflecting the will of the people. For instance, the ability of Parliament to repeal or amend any legislation, as demonstrated in cases like Burmah Oil Co Ltd v. Lord Advocate [1965] AC 75, reinforced the notion of absolute sovereignty. However, this classical view presupposes a static constitutional framework, arguably failing to account for the dynamic political and legal changes that have since emerged.
Challenges from Constitutional Developments
Several constitutional developments have eroded the absoluteness of parliamentary supremacy. The UK’s membership in the European Union, until Brexit in 2020, introduced a significant limitation through the European Communities Act 1972, which mandated that EU law took precedence over domestic legislation in areas of conflict, as seen in Factortame Ltd v. Secretary of State for Transport (No.2) [1991] 1 AC 603. Although Brexit has restored some legislative autonomy, the European Court of Human Rights’ influence under the Human Rights Act 1998 continues to challenge Dicey’s vision by empowering courts to issue declarations of incompatibility when Acts of Parliament contradict Convention rights. These mechanisms, while not nullifying legislation, indicate a shift towards a more balanced constitutional order where parliamentary power is no longer wholly unassailable.
Judicial Attitudes and the Rule of Law
Judicial pronouncements, such as Lord Steyn’s in Jackson, reflect growing unease with unchecked parliamentary power, particularly when it conflicts with fundamental principles like the rule of law. In Jackson, the House of Lords debated whether the Hunting Act 2004, passed under the Parliament Acts, could be challenged, with some judges suggesting that extreme legislation undermining democracy might not be upheld (R (Jackson and Others) v. Attorney General [2005] UKHL 56). Furthermore, Lord Hope’s comments on the potential limits of parliamentary sovereignty in AXA General Insurance Ltd v. Lord Advocate [2011] UKSC 46 signal a judicial willingness to reconsider Dicey’s absolutist stance in light of modern constitutional values. This evolving judicial perspective highlights a tension between traditional doctrine and contemporary expectations of rights protection.
Conclusion
In summary, while Dicey’s doctrine of parliamentary supremacy remains a foundational concept in UK public law, its ‘pure and absolute’ nature is increasingly questioned. Constitutional innovations, such as the Human Rights Act and historical EU membership, alongside shifting judicial attitudes, demonstrate that parliamentary power is no longer unconstrained. Lord Steyn’s observation in Jackson aptly captures this tension, suggesting that the classic account struggles to accommodate the complexities of the modern UK constitution. The implications of this evolution are significant, pointing towards a future where parliamentary supremacy may need to coexist with other principles, such as the rule of law, to ensure a balanced and just legal framework.
