Introduction

Parliamentary sovereignty and the rule of law are conventionally regarded as the twin pillars of the UK constitution (Dicey, 1885). Yet these two principles increasingly pull in opposite directions. Parliamentary sovereignty, in its orthodox formulation, holds that Parliament may enact any law whatsoever and that no body may override or set aside an Act of Parliament. The rule of law, by contrast, demands that all power — including legislative power — be exercised within limits set by fundamental legal principles. The tension between these doctrines is not merely theoretical: it has generated significant judicial dicta, scholarly disagreement, and practical constitutional friction, particularly since the enactment of the Human Rights Act 1998 (HRA), the Constitutional Reform Act 2005, and the United Kingdom’s withdrawal from the European Union.

This essay argues that parliamentary sovereignty and the rule of law remain formally compatible in the UK constitution, but that this compatibility is increasingly strained and depends upon a set of constitutional conventions, institutional self-restraint, and interpretive practices that are themselves contestable and fragile. The orthodox Diceyan synthesis — in which sovereignty and the rule of law coexist because Parliament legislates within a legal framework administered by independent courts — conceals a deeper structural tension. Where Parliament exercises its sovereign power to curtail access to justice, oust judicial review, or override fundamental rights, the two doctrines collide. The compatibility thesis survives only because the judiciary has, to date, preferred creative statutory interpretation and obiter warnings over outright constitutional confrontation. Whether this equilibrium can endure in the face of growing executive dominance of Parliament, the removal of EU law constraints, and legislative challenges to judicial independence is the central question of contemporary UK public law.

The Orthodox Position: Dicey’s Reconciliation of Sovereignty and the Rule of Law

The starting point is A.V. Dicey’s Introduction to the Study of the Law of the Constitution (1885), which treated parliamentary sovereignty and the rule of law as complementary rather than conflicting. For Dicey, parliamentary sovereignty meant that Parliament had “the right to make or unmake any law whatever; and, further, that no person or body is recognised by the law of England as having a right to override or set aside the legislation of Parliament” (Dicey, 1885, p. 39). The rule of law, in Dicey’s tripartite formulation, required the absence of arbitrary power, equality before the law, and the derivation of constitutional principles from the ordinary law as enforced by the courts (Dicey, 1885, pp. 107–122).

Dicey reconciled these principles by assigning them different functions. Sovereignty described the source of law; the rule of law described the manner of its administration. Parliament made law; the courts applied it impartially and ensured that government action was authorised by law. On this view, there is no conflict: Parliament may change any legal rule, but until it does, the existing law governs everyone, including the executive. The rule of law operates within the framework set by sovereign legislation, rather than as an external constraint upon Parliament itself.

This synthesis has been remarkably durable. In Madzimbamuto v Lardner-Burke [1969] 1 AC 645, Lord Reid famously observed that it was “often said that it would be unconstitutional for the United Kingdom Parliament to do certain things… but that does not mean that it is beyond the power of Parliament to do such things” (at 723). The orthodox view thus treats the rule of law as a principle governing the executive and the judiciary, but not Parliament in its legislative capacity. Parliament’s compliance with the rule of law is a matter of political convention and self-restraint, not legal obligation.

However, the persuasiveness of Dicey’s reconciliation depends on assumptions that have become increasingly difficult to sustain. Dicey assumed a Parliament that would not, in practice, legislate in ways fundamentally destructive of the rule of law. He also assumed that judicial independence and access to justice were sufficiently protected by constitutional convention. Both assumptions are now open to serious question.

The Rule of Law as a Substantive Constitutional Principle

A significant development has been the gradual judicial recognition that the rule of law is not merely a descriptive feature of the constitution but a substantive legal principle with normative force. This shift is critical to the compatibility question because, the more robust the constitutional content of the rule of law, the greater the potential for conflict with parliamentary sovereignty.

The most significant judicial articulation of this position is Lord Bingham’s account in R (Bingham) v Secretary of State for the Home Department — though it is Lord Bingham’s extra-judicial writing that provides the fullest statement. In The Rule of Law (2010), Lord Bingham identified eight sub-principles, including that the law must be accessible, intelligible and predictable; that questions of legal right and liability should ordinarily be resolved by law and not by the exercise of discretion; that the law must afford adequate protection of fundamental human rights; and that the state must comply with its obligations in international as well as national law (Bingham, 2010, pp. 37–129). Lord Bingham explicitly acknowledged the tension with parliamentary sovereignty, observing that if Parliament were to enact “a grossly unjust or oppressive statute,” the rule of law would require the courts to give effect to it, yet such legislation would itself represent “a violation of the rule of law” (Bingham, 2010, p. 167).

This acknowledgement is revealing. It concedes that the Diceyan reconciliation breaks down at the extremes. If Parliament enacts legislation that is itself contrary to the rule of law — for example, legislation that retrospectively criminalises conduct, ousts all judicial review, or permits indefinite executive detention without charge — the two principles are placed in direct opposition. The courts must either enforce the statute (upholding sovereignty at the expense of the rule of law) or refuse to enforce it (upholding the rule of law at the expense of sovereignty).

The Constitutional Reform Act 2005, s 1, provides that the Act “does not adversely affect… the existing constitutional principle of the rule of law.” This statutory recognition is significant, though its precise legal effect remains debated. Craig (2007) argues that the provision does not elevate the rule of law above parliamentary sovereignty, since it is itself a product of statute and could be repealed. Elliott (2004) contends, by contrast, that the rule of law operates as a constitutional principle that the courts may invoke to inform interpretation of legislation, and potentially to impose limits on what counts as valid law. The provision is, at minimum, an acknowledgement by Parliament itself that the rule of law is a foundational principle capable of constraining the exercise of public power.

Judicial Review and the Common Law Constitution: R (Jackson) v Attorney General

The most direct judicial engagement with the compatibility question arose in R (Jackson) v Attorney General [2005] UKHL 56. The case concerned the validity of the Hunting Act 2004, enacted under the Parliament Acts 1911 and 1949 without the consent of the House of Lords. Although the majority upheld the Act’s validity on conventional grounds, several Law Lords made obiter observations of extraordinary constitutional significance.

Lady Hale stated that “the courts will treat with particular suspicion (and might even reject) any attempt to subvert the rule of law by removing governmental action affecting the rights of the individual from all judicial scrutiny” (at [159]). Lord Steyn went further, suggesting that the doctrine of parliamentary sovereignty was “a construct of the common law” and that the courts could, in extreme circumstances, qualify it. He stated: “the supremacy of Parliament is still the general principle of our constitution. It is a construct of the common law. The judges created this principle. If that is so, it is not unthinkable that circumstances could arise where the courts may have to qualify a principle established on a different hypothesis of constitutionalism” (at [102]). Lord Hope similarly observed that parliamentary sovereignty “is no longer, if it ever was, absolute” and that the rule of law “enforced by the courts is the ultimate controlling factor on which our constitution is based” (at [107]).

These dicta represent a fundamental challenge to the orthodox position. If parliamentary sovereignty is a common law creation, then the common law — interpreted and applied by the judiciary — may in principle modify or limit it. This reasoning inverts Dicey’s hierarchy: rather than the rule of law operating within sovereign legislation, sovereignty itself operates within the rule of law as judicially understood. The implications are radical, although they remain, for the moment, confined to obiter dicta rather than binding holdings.

Allan (2011) has argued that parliamentary sovereignty and the rule of law are not merely compatible but conceptually interdependent: sovereignty is only intelligible as a legal concept within a system governed by the rule of law, and legislation that destroys the conditions for the rule of law thereby undermines the very framework that gives sovereignty its legal meaning. This is an elegant theoretical synthesis, but it has been criticised by Goldsworthy (2010), who argues that the orthodox doctrine of sovereignty is a political fact recognised by the legal system rather than a common law construct that the courts are free to revise. On Goldsworthy’s view, the judiciary has no authority to override a clear and unambiguous Act of Parliament, however objectionable its content, because sovereignty is a foundational commitment of the constitutional order that precedes and conditions the authority of the courts.

The Human Rights Act 1998: Structured Mediation Between Sovereignty and the Rule of Law

The enactment of the Human Rights Act 1998 represents the most significant institutional attempt to mediate the tension between parliamentary sovereignty and the rule of law. The HRA incorporates most of the rights contained in the European Convention on Human Rights (ECHR) into domestic law, but does so in a manner expressly designed to preserve parliamentary sovereignty.

Under s 3(1), courts must read and give effect to primary legislation “in a way which is compatible with the Convention rights,” “so far as it is possible to do so.” Under s 4, where a court cannot interpret legislation compatibly, it may issue a declaration of incompatibility, which does not affect the validity, continuing operation or enforcement of the provision in question (s 4(6)). Parliament may, but is not obliged to, amend the law in response. This structure preserves the formal supremacy of Parliament: the courts cannot strike down or disapply primary legislation on human rights grounds.

In practice, however, the s 3 interpretive obligation has been used to produce readings of legislation that depart significantly from their ordinary meaning. In Ghaidan v Godin-Mendoza [2004] UKHL 30, the House of Lords read the Rent Act 1977, Sch 1, para 2 as if the words “as his or her wife or husband” included same-sex partners — a reading that would have been impossible under ordinary principles of statutory interpretation. Lord Steyn observed that s 3 required the court to adopt an interpretation that was “linguistically possible” even if it was not the “most natural” reading (at [44]–[49]). This approach effectively allows the courts to rewrite legislation to achieve Convention compliance, albeit under the formal rubric of interpretation rather than invalidation.

The HRA thus creates a de facto system of weak-form judicial review (Tushnet, 2008), in which the courts protect fundamental rights but the final legislative word remains with Parliament. This structure is widely regarded as the most successful reconciliation of sovereignty and the rule of law in the modern constitution (Kavanagh, 2009). However, its success depends on two conditions: first, that the s 3 interpretive power is exercised with restraint, so that it does not become a disguised form of judicial legislation; and second, that Parliament takes declarations of incompatibility seriously and acts upon them. Where either condition fails, the mediation breaks down. If the courts stretch s 3 too far, they encroach on sovereignty; if Parliament ignores declarations of incompatibility, the rule of law is diminished.

The record on declarations of incompatibility is mixed. Research conducted by the Ministry of Justice indicates that successive governments have generally responded to declarations by amending the offending legislation (Ministry of Justice, 2022). Nevertheless, there is no legal obligation to do so, and the political climate surrounding human rights adjudication has become increasingly hostile. The proposal to replace the HRA with a “British Bill of Rights” — manifested in the Bill of Rights Bill 2022, which was subsequently withdrawn — illustrated the fragility of the existing settlement. Had that Bill been enacted in its original form, it would have significantly curtailed the s 3 interpretive obligation and limited the circumstances in which declarations of incompatibility could be issued, thereby reducing the courts’ capacity to enforce the rule of law against sovereign legislation (Joint Committee on Human Rights, 2022).

Ouster Clauses and Access to Justice: The Sharpest Point of Conflict

The most acute conflict between parliamentary sovereignty and the rule of law arises in relation to ouster clauses — statutory provisions that purport to exclude or restrict judicial review of executive action. If Parliament is truly sovereign, it can enact an effective ouster clause; if the rule of law requires access to independent adjudication, such clauses are constitutionally suspect.

The leading authority remains Anisminic Ltd v Foreign Compensation Commission [1969] 2 AC 147, in which the House of Lords held that a clause providing that “the determination [of the Commission] shall not be called in question in any court of law” did not protect a determination that was a nullity by reason of jurisdictional error. The effect of Anisminic was to render most ouster clauses ineffective by classifying any legal error as jurisdictional, thereby taking the impugned decision outside the scope of the ouster. The reasoning rested on a presumption that Parliament does not intend to exclude judicial review of unlawful action — a presumption that is itself a manifestation of the rule of law operating as an interpretive principle within the framework of sovereignty.

The more recent decision in R (Privacy International) v Investigatory Powers Tribunal [2019] UKSC 22 reaffirmed and extended the Anisminic principle. The Supreme Court held, by a majority, that an ouster clause in the Regulation of Investigatory Powers Act 2000, s 67(8), did not exclude judicial review for errors of law. Lord Carnwath, delivering the leading majority judgment, treated the rule of law as the “ultimate controlling factor” and stated that Parliament was presumed not to intend to immunise unlawful action from judicial scrutiny (at [131]). Lord Sumption, dissenting, argued that the majority had effectively rewritten the statute and that the true constitutional position required the courts to give effect to a clear ouster clause (at [196]–[210]). The disagreement between the majority and the dissent crystallises the fundamental tension: the majority prioritised the rule of law; the dissent prioritised parliamentary sovereignty.

The significance of Privacy International extends beyond the individual case. If the courts will always read down ouster clauses on rule of law grounds, then parliamentary sovereignty is, in practice, limited: Parliament cannot effectively exclude judicial review regardless of the clarity of its statutory language. This is precisely the conclusion that critics such as Ekins (2019) resist. Ekins argues that the rule of law does not empower judges to override clear legislative choices and that the judicial approach to ouster clauses amounts to an illegitimate assertion of judicial supremacy. By contrast, Elliott (2020) contends that the judicial approach is a legitimate exercise of the interpretive function, operating within — not against — sovereignty, by giving effect to Parliament’s presumed intention to legislate consistently with fundamental constitutional principles.

The practical significance of this debate was highlighted by the Judicial Review and Courts Act 2022, which introduced a statutory presumption in favour of prospective-only quashing orders and suspended quashing orders (ss 1 and 2). Although these provisions stop short of a full ouster clause, they represent an attempt to constrain the remedial discretion of the courts in judicial review proceedings. The Independent Review of Administrative Law, chaired by Lord Faulks, concluded that no fundamental reform of judicial review was necessary (Independent Review of Administrative Law, 2021). The government’s subsequent legislative response went further than the panel had recommended, suggesting an executive-driven desire to limit judicial oversight that is itself in tension with the rule of law.

The Impact of EU Withdrawal: Sovereignty Regained, Rule of Law Diminished?

The United Kingdom’s withdrawal from the European Union represents a significant shift in the relationship between parliamentary sovereignty and the rule of law. Membership of the EU operated as a form of constitutional constraint on parliamentary sovereignty, most visibly through the doctrine of supremacy of EU law as recognised in R v Secretary of State for Transport, ex parte Factortame Ltd (No 2) [1991] 1 AC 603. The House of Lords in Factortame accepted that directly effective EU law took priority over inconsistent Acts of Parliament — a position that was formally incompatible with orthodox sovereignty but was justified as a consequence of the European Communities Act 1972, s 2(1).

The European Union (Withdrawal) Act 2018 repealed the European Communities Act and provided for the retention of EU-derived law as “retained EU law” (s 2). The Retained EU Law (Revocation and Reform) Act 2023 subsequently established a mechanism for the executive to revoke, replace or restate retained EU law by statutory instrument, with a sunset provision for specified categories of retained law. The constitutional significance of this legislation lies in the transfer of what was formerly primary or directly effective law into a form that can be modified or abolished by ministerial action, subject to limited parliamentary scrutiny.

From the perspective of parliamentary sovereignty, EU withdrawal has removed an external legal constraint on Parliament’s legislative competence. From the perspective of the rule of law, however, the withdrawal raises concerns. The broad delegated powers conferred by the withdrawal legislation permit the executive to alter substantive legal rights — including employment rights, environmental protections, and consumer protections derived from EU law — without primary legislation. This transfer of legislative power from Parliament to the executive diminishes parliamentary accountability and reduces the scope for judicial oversight, both of which are essential components of the rule of law (Elliott and Thomas, 2020, pp. 275–278).

The broader constitutional implication is that the restoration of formal parliamentary sovereignty has not been accompanied by a corresponding strengthening of rule of law safeguards. On the contrary, the mechanisms chosen for managing the post-Brexit legal landscape have concentrated power in the executive, weakened parliamentary scrutiny, and created legal uncertainty — precisely the conditions that the rule of law is intended to prevent.

The Prorogation Case: A Constitutional Moment

The decision of the Supreme Court in R (Miller) v The Prime Minister [2019] UKSC 41 (the prorogation case) provides a further illustration of the tension between sovereignty and the rule of law. The Court unanimously held that the Prime Minister’s advice to the Queen to prorogue Parliament for five weeks was unlawful and void. The constitutional basis of the decision was that prorogation had the effect of frustrating Parliament’s ability to carry out its constitutional functions, including its function of holding the executive to account.

Lady Hale and Lord Reed, delivering the judgment of the Court, grounded the decision in two constitutional principles: parliamentary sovereignty and parliamentary accountability. They held that the executive could not use the prerogative power to prorogue Parliament in a way that prevented Parliament from performing its legislative and scrutiny functions without reasonable justification (at [50]). Notably, the Court presented sovereignty and the rule of law not as conflicting principles but as jointly requiring the conclusion that the prorogation was unlawful.

The prorogation case is significant for the compatibility question because it demonstrates that the judiciary is willing to intervene to protect the constitutional conditions for the exercise of sovereignty — even against the wishes of the executive acting through the prerogative. The rule of law, on this approach, is not merely a constraint on the legislature but a principle that protects the legislature from executive overreach. This is a powerful reconciliation of the two doctrines, but it depends on a conception of the rule of law that extends beyond formal legality to encompass constitutional accountability. Critics such as Finnis (2019) argued that the Court had exceeded its proper constitutional role by adjudicating an inherently political question. Defenders, including Elliott (2019), argued that the case was a straightforward application of the principle that executive power must be exercised within legal limits.

Theoretical Perspectives: Can the Tension Be Resolved?

The academic literature reveals three broad approaches to the compatibility question. The first, associated with the orthodox or “political constitutionalist” tradition exemplified by Dicey and later by Griffith (1979), holds that parliamentary sovereignty is the foundational principle and that the rule of law operates within the framework it establishes. On this view, compatibility is maintained because the rule of law makes no claim to override parliamentary sovereignty; it merely requires that government operates according to law as Parliament has enacted it. The principal weakness of this position is that it provides no legal remedy where Parliament itself legislates contrary to the rule of law.

The second approach, associated with common law constitutionalism and advanced by Laws (1995), Allan (2001) and, in judicial form, by Lord Steyn in Jackson, holds that the rule of law is the more fundamental principle and that parliamentary sovereignty is a common law construct that may be qualified where necessary to protect fundamental rights and constitutional essentials. This position provides a stronger protection for the rule of law but faces the objection that it is democratically illegitimate: unelected judges would be empowered to override the decisions of the elected legislature on the basis of judicially determined constitutional values.

The third approach, associated with what Kavanagh (2009) terms “collaborative constitutionalism,” holds that sovereignty and the rule of law are best reconciled through institutional dialogue rather than hierarchy. On this view, the HRA model — in which courts interpret legislation in light of fundamental rights, issue declarations of incompatibility, and leave the final word to Parliament — represents the most defensible accommodation of the two principles. The strength of this approach is that it avoids the extremes of either unconstrained sovereignty or judicial supremacy. Its weakness is that dialogue depends on good faith and institutional self-restraint on both sides. Where the political branches refuse to engage — or actively seek to undermine the courts’ capacity to protect the rule of law — dialogue becomes a polite fiction.

A fourth, less prominent but intellectually important perspective is offered by Poole (2015), who argues that the dichotomy between sovereignty and the rule of law is itself misleading. Poole contends that both concepts are internally complex and contested, and that the real question is not which principle “wins” in the event of a conflict but how the constitution distributes authority among institutions in a way that maintains an acceptable balance of power. This institutional perspective has the merit of directing attention away from abstract doctrinal hierarchies and towards the practical mechanisms — parliamentary procedure, judicial review, conventions, political culture — through which constitutional government is actually maintained.

Contemporary Pressures: Executive Dominance and Legislative Challenges to the Judiciary

The practical compatibility of sovereignty and the rule of law is currently under strain from a number of developments that merit brief examination. First, the growing dominance of the executive over the legislative process means that parliamentary sovereignty increasingly functions as a vehicle for executive power rather than as an independent expression of legislative will. Where the government commands a reliable parliamentary majority and controls the legislative timetable, Acts of Parliament may more accurately be described as acts of the executive enacted through Parliament (Tomkins, 2005, p. 89). This has implications for the rule of law because it undermines the assumption — central to Dicey’s reconciliation — that Parliament acts as an independent check on executive power.

Second, recent legislative proposals have directly challenged the capacity of the courts to enforce the rule of law. The Illegal Migration Act 2023, for example, imposes duties on the Secretary of State to remove individuals who arrive in the UK without prior authorisation, and restricts the circumstances in which courts and tribunals can grant interim relief to prevent removal. The Rwanda policy, as considered in R (AAA) v Secretary of State for the Home Department [2023] UKSC 42, resulted in the Supreme Court finding that removal to Rwanda would expose individuals to a real risk of refoulement contrary to Article 3 ECHR. The government’s response — the Safety of Rwanda (Asylum and Immigration) Act 2024 — sought to override the Supreme Court’s finding of fact by legislatively declaring Rwanda to be a safe country (s 1). This legislation represents a direct attempt by Parliament to override a judicial finding on rule of law grounds, and it raises profound questions about the limits of parliamentary sovereignty. If Parliament can legislate to declare facts that the courts have found to be untrue, the rule of law — which depends on the independent determination of factual and legal questions by the judiciary — is fundamentally compromised.

The Safety of Rwanda Act is arguably the clearest modern example of legislation in which parliamentary sovereignty and the rule of law are brought into direct conflict. The Act does not merely change the legal rules; it purports to change reality by legislative fiat. Craig (2024) argues that such legislation undermines the constitutional division of function between Parliament and the courts: Parliament’s role is to make law; the courts’ role is to determine facts and apply law to facts. Where Parliament legislates to override judicial findings of fact, it trespasses on the judicial function in a manner that is incompatible with the rule of law.

The Compatibility Thesis Reconsidered

Drawing the threads together, the compatibility of parliamentary sovereignty and the rule of law in the modern UK constitution depends on which conception of each principle is adopted and on the institutional conditions in which they operate. If sovereignty is understood in its strongest orthodox sense — that Parliament may enact any law whatsoever — and the rule of law is understood in a substantive sense — that all power must be exercised consistently with fundamental rights and the principles of legality — then the two principles are, at the margins, incompatible. A Parliament that enacts legislation ousting judicial review, overriding judicial findings of fact, or authorising arbitrary executive detention exercises its sovereignty in a manner that is destructive of the rule of law.

The two principles have, in practice, been held in equilibrium by a set of mediating devices: the principle of legality, which requires clear words before fundamental rights will be taken to have been overridden (R v Secretary of State for the Home Department, ex parte Simms [2000] 2 AC 115, per Lord Hoffmann at 131); the interpretive obligation under HRA s 3; the declaration of incompatibility mechanism under HRA s 4; the judicial presumption against ouster clauses; and the political conventions that discourage Parliament from legislating in ways that are fundamentally offensive to the rule of law. Each of these devices is a compromise that preserves the formal structure of sovereignty while giving practical effect to the rule of law.

The difficulty is that each of these mediating devices depends on contested interpretive choices and political goodwill. The principle of legality is a presumption that can be displaced by sufficiently clear statutory language. Section 3 of the HRA can be repealed or curtailed. Declarations of incompatibility can be ignored. Ouster clauses can be drafted with increasing specificity to overcome judicial resistance. And constitutional conventions can be broken without legal sanction. In short, every rule of law safeguard in the UK constitution is vulnerable to the exercise of parliamentary sovereignty. The compatibility of the two principles is not a structural feature of the constitution but a contingent achievement that depends on the choices of political actors and the willingness of the judiciary to defend constitutional values.

Conclusion

The doctrine of parliamentary sovereignty remains formally compatible with the rule of law in the UK constitution, but this compatibility is conditional, contested, and increasingly precarious. The Diceyan synthesis, in which sovereignty and the rule of law occupy complementary roles, was always more fragile than its elegant simplicity suggested. The modern constitution has developed a sophisticated set of mediating mechanisms — the HRA, the principle of legality, the presumption against ouster clauses, and the institutional dialogue between courts and Parliament — that enable the two principles to coexist in practice. However, these mechanisms operate as interpretive conventions and statutory frameworks, not as entrenched constitutional guarantees. They depend on a political culture that respects the independence of the judiciary, the accessibility of justice, and the protection of fundamental rights.

The strongest reason for concluding that the two doctrines remain compatible is that the judiciary has, even in its most adventurous moments, stopped short of claiming the power to invalidate primary legislation. The obiter dicta in Jackson and the reasoning in Privacy International suggest a judicial willingness to defend the rule of law at the interpretive level, but no UK court has yet struck down an Act of Parliament on constitutional grounds. Sovereignty retains its formal primacy. Yet the growing willingness of the political branches to legislate in ways that directly challenge the rule of law — ousting judicial review, overriding judicial findings, and concentrating legislative power in the executive — places this equilibrium under unprecedented stress. The compatibility of sovereignty and the rule of law is not an inherent feature of the UK constitution; it is a political achievement that requires constant defence. The extent to which it endures will depend less on doctrinal analysis than on the institutional resilience of Parliament, the courts, and the broader constitutional culture within which they operate.
