Introduction
This essay critically examines Lord Steyn’s statement in R (Jackson) v Attorney General [2005] UKHL 5 at [102], where he questions the absolute nature of parliamentary sovereignty in the modern United Kingdom, suggesting that it is a common law construct potentially subject to judicial qualification under certain circumstances. His remarks invite a deeper exploration of the tension between parliamentary sovereignty—the cornerstone of the UK constitutional framework—and the rule of law, a fundamental principle ensuring legal governance and accountability. This discussion will assess the historical and theoretical foundations of parliamentary sovereignty, evaluate the evolving role of the judiciary in shaping constitutional principles, and consider how the rule of law might challenge or complement this doctrine. Ultimately, the essay argues that while parliamentary sovereignty remains a central tenet, its interaction with the rule of law and judicial oversight indicates a shifting constitutional landscape that may necessitate re-evaluation of traditional assumptions.
The Doctrine of Parliamentary Sovereignty: Historical and Theoretical Foundations
Parliamentary sovereignty, often described as the bedrock of the UK constitution, holds that Parliament possesses the ultimate legal authority to make or repeal any law, without limitation by higher authority or prior legislation (Dicey, 1885). This principle, articulated by A.V. Dicey, implies that no court or other body can question the validity of an Act of Parliament, positioning it as the highest source of law. Historically, this doctrine emerged from the Glorious Revolution of 1688-89 and the subsequent Bill of Rights 1689, which established Parliament’s dominance over the monarchy and entrenched its legislative supremacy.
However, Lord Steyn’s statement challenges the purity of this doctrine, describing it as “out of place” in the modern UK. He suggests that the absolute nature of sovereignty, as Dicey envisioned, does not fully align with contemporary constitutional realities shaped by membership in international frameworks (such as the European Union at the time of the Jackson case), the Human Rights Act 1998, and devolution arrangements. Indeed, the Factortame litigation, notably R v Secretary of State for Transport, ex parte Factortame Ltd (No 2) [1991] 1 AC 603, demonstrated that UK courts could disapply domestic legislation conflicting with EU law, thereby qualifying Parliament’s unfettered authority (Wade, 1996). This development illustrates that parliamentary sovereignty, while still a general principle, operates within a broader context that imposes practical constraints.
Parliamentary Sovereignty as a Common Law Construct
Lord Steyn’s assertion that parliamentary sovereignty is a “construct of the common law” created by judges is particularly significant. This perspective underscores the judiciary’s role in defining and sustaining the doctrine. Historically, judicial pronouncements in cases such as Dr. Bonham’s Case (1610) 8 Co Rep 107a, where Sir Edward Coke suggested that common law could control Acts of Parliament contrary to reason, hinted at early judicial influence over legislative power, though this view was later overtaken by Diceyan orthodoxy (Loveland, 2018). Nevertheless, Steyn’s view aligns with the argument that sovereignty is not an inherent or immutable truth but a principle shaped and upheld by judicial recognition.
If sovereignty is a judicial creation, as Steyn posits, it follows that judges retain the capacity to adapt or qualify it in response to changing constitutional hypotheses. This possibility raises questions about the balance of power between Parliament and the courts. For instance, in the Jackson case itself, concerning the validity of the Hunting Act 2004 passed under the Parliament Acts 1911 and 1949, the House of Lords affirmed Parliament’s legislative authority while subtly acknowledging potential limits. Lord Steyn’s obiter remarks suggest that in extreme circumstances—perhaps involving a grave violation of constitutional norms—courts might intervene to redefine sovereignty’s scope, highlighting a critical intersection with the rule of law.
The Rule of Law and Its Tension with Parliamentary Sovereignty
The rule of law, a principle championed by Dicey alongside parliamentary sovereignty, demands that all are subject to the law, including the government, and that laws must be clear, accessible, and applied consistently (Dicey, 1885). In theory, parliamentary sovereignty and the rule of law should coexist harmoniously, as Parliament’s legislative power enables the creation of laws that uphold legal certainty and fairness. However, in practice, tensions arise when Parliament enacts legislation that undermines fundamental rights or legal principles, as arguably occurred with certain anti-terrorism measures post-9/11, such as indefinite detention provisions challenged in A v Secretary of State for the Home Department [2004] UKHL 56 (Bingham, 2007).
Lord Steyn’s suggestion that courts might “qualify” sovereignty under exceptional circumstances reflects the judiciary’s growing willingness to protect the rule of law against potential parliamentary overreach. For example, in Anisminic Ltd v Foreign Compensation Commission [1969] 2 AC 147, the House of Lords effectively nullified an ouster clause attempting to shield administrative decisions from judicial review, reinforcing the judiciary’s role as guardian of legality. More recently, R (Miller) v Secretary of State for Exiting the European Union [2017] UKSC 5 underscored the judiciary’s insistence on parliamentary involvement in significant constitutional changes, such as triggering Article 50, thereby ensuring adherence to legal and democratic processes (Elliott, 2017). These cases illustrate that while parliamentary sovereignty remains paramount, the rule of law serves as a counterbalance, potentially justifying judicial qualification of sovereignty in extreme scenarios.
Critical Evaluation: Balancing Sovereignty and Judicial Oversight
While Lord Steyn’s remarks are thought-provoking, they must be approached with caution. Critics might argue that any judicial attempt to qualify parliamentary sovereignty risks undermining democratic legitimacy, as Parliament, representing the electorate, should retain ultimate authority (Goldsworthy, 2010). Indeed, the unelected nature of the judiciary raises concerns about their mandate to override legislative decisions, potentially leading to accusations of judicial overreach. Conversely, proponents of Steyn’s view contend that the rule of law necessitates judicial intervention in exceptional cases to prevent tyranny or gross injustice, particularly in the absence of a codified constitution to constrain parliamentary power (Allan, 2013).
Furthermore, the practical likelihood of courts qualifying sovereignty remains speculative. Despite Steyn’s hypothetical, no UK court has explicitly refused to enforce an Act of Parliament on substantive grounds, indicating a deep-rooted deference to parliamentary authority. Nonetheless, the evolving constitutional landscape, shaped by international obligations and domestic human rights commitments, suggests that sovereignty is not as absolute as once thought. This tension underscores the need for a nuanced understanding of constitutionalism, where sovereignty and the rule of law are not mutually exclusive but interdependent principles requiring careful balance.
Conclusion
In conclusion, Lord Steyn’s statement in R (Jackson) v Attorney General [2005] UKHL 5 at [102] challenges the traditional absolutism of parliamentary sovereignty, highlighting its status as a common law construct potentially subject to judicial qualification. This essay has explored the historical roots and theoretical underpinnings of sovereignty, the judiciary’s role in shaping constitutional principles, and the critical interplay with the rule of law. While sovereignty remains the general principle of the UK constitution, cases such as Factortame and Miller demonstrate that it operates within a broader framework of legal and political constraints. Steyn’s remarks, though speculative, invite important reflection on the judiciary’s responsibility to uphold the rule of law, particularly in exceptional circumstances. Arguably, this dynamic relationship between sovereignty and the rule of law reflects a maturing constitutional order, necessitating ongoing dialogue about the limits of legislative power and the judiciary’s protective role. The implications of this debate are profound, shaping how the UK navigates future constitutional challenges in an increasingly complex legal environment.
