The Great Myth of Parliamentary Supremacy: Why the Common Law is King and Statement of Case

What if one of the most fundamental principles of the UK’s constitution—the absolute supremacy of Parliament—wasn’t a timeless truth, but a myth created and maintained by the courts themselves?

This isn’t a radical conspiracy theory. It’s an argument based on a rigorous application of logic and a close reading of the UK’s own legal history and, is based only on primary sources rather than people’s opinions which are secondary sources. The conclusion is as startling as it is simple: Parliament’s power is not supreme. It is derived from, and therefore subject to, the ultimate authority of the common law—the law of reason and logic that is the true birthright of the people.

The Clue Hiding in Plain Sight: The Courts Created the “Myth”

The conventional view is that Parliament can make or unmake any law it chooses. Yet, the judiciary itself tells a different story. As Lord Hoffmann stated in the

Bancoult case, “The principle of the sovereignty of Parliament, as it has been developed by the courts over the past 350 years, is founded upon the unique authority Parliament derives from its representative character.”¹

This is a critical admission. If the courts “developed” this principle, it cannot be an inherent, self-generating power. Logically, a creator cannot grant an authority greater than its own. The judiciary is subject to the law; therefore, any power it “develops” and recognises must come from a higher source.

The True Source: Common Law as the Foundation of All Authority

That higher source is the common law.

The common law is not just a collection of old cases; by its very definition, it is logic and reason applied to resolve disputes, more commonly known as common law precedent. It predates Parliament and forms the bedrock of the UK’s legal system.

Consider this: Parliament’s power to create statute law is given effect by Royal Assent. This power, the royal prerogative, does not exist in a vacuum. It is explicitly bound by the common law. The Confirmation of the Charters 1297, a foundational constitutional text, states this is “the Common Law”.²

The logic is inescapable:

The Crown’s power to give Royal Assent comes from the common law.
Parliament’s power to legislate depends on Royal Assent.
Therefore, statute law is a product of a power that is itself subject to the common law.

By logical impossibility, a creation (statute law) cannot be superior to its creator (the common law).

What is a Statute? An Equitable Claim, Not an Unchallengeable Command

This reframes what a statute actually is. It is not an unchallengeable command. In law, it can only be understood as an equitable claim—a statutory demand made by Parliament. And like any other act of governance, it must be lawful.

The core principle that “no one is above the law” must apply to Parliament as well. The judiciary’s role is to test the lawfulness of these statutory claims against the higher principles of common law and equity.

The law itself confirms this hierarchy. Section 49 of the Senior Courts Act 1981 explicitly states that where the rules of common law and the rules of equity conflict,

the rules of equity shall prevail.⁵ Equity is, in essence, fairness and justice. This means our courts have a statutory duty to ensure a just outcome, even if it requires deeming an Act of Parliament “unlawful” in its effect.

This isn’t a new idea. In 1610, Chief Justice Coke noted in

Dr Bonham’s Case that “when an Act of Parliament is against common right and reason… the common law will controul it.”⁷ While debated, the core principle—that law must answer to reason—remains.

Your Birthright: The Law is Not What Parliament Says It Is

Constitutional documents like the Bill of Rights 1689 and the Act of Settlement 1700 are not grants of absolute power to Parliament; they are power-sharing agreements that constrain Parliament.

The Act of Settlement 1700 affirms that “the Laws of England are the Birthright of the People thereof”.¹¹ It does not say “statute law” is the birthright. It refers to a higher, pre-existing legal framework that belongs to the people and which binds the monarch and, by extension, the Parliament they authorise.

Conclusion: Reclaiming Reason

The idea that Parliament is the supreme creator of law is a persuasive myth, but a myth nonetheless—one developed by the courts. The ultimate authority is, and has always been, the common law, embodying the logic and reason needed to resolve disputes fairly.

Statute law is not a final command, but an equitable claim that must be lawful and rational. One Parliament cannot bind another for the same reason one person cannot bind another without consent—it violates the principle of equality under the law. ¹⁴

The courts’ true duty is not to blindly enforce the will of Parliament, but to decide cases according to this overarching law. They must ensure that statutes—and the governments that enact them—are held accountable to the evolving truths created by logic, reason, and justice.

STATEMENT OF CASE

IN THE MATTER OF THE NATURE OF PARLIAMENTARY SOVEREIGNTY AND THE HIERARCHY OF LAW IN THE UNITED KINGDOM

Introduction This Statement of Case challenges the conventional understanding of parliamentary supremacy as the supreme and unchallengeable source of law in the United Kingdom. It is submitted that, upon a rigorous application of logic and reason to primary legal authorities, the notion of Parliament as the ultimate, self-originating creator of binding law is revealed to be a judicial construct, a “myth” developed by the courts themselves, and that statute law remains fundamentally subject to the overarching principles of common law and equity.

Parliamentary Sovereignty: A Judicial Creation, Not an Inherent Power

2.1 The foundational claim that Parliament is the supreme legal authority, capable of creating or ending any law, is not derived from an inherent, self-granted power, nor from an external, higher authority. Instead, it is a principle explicitly acknowledged by the judiciary as its own creation. Lord Hoffmann, in R (Bancoult) v Secretary of State for Foreign and Commonwealth Affairs (No 2), directly stated: “The principle of the sovereignty of Parliament, as it has been developed by the courts over the past 350 years, is founded upon the unique authority Parliament derives from its representative character.”¹

2.2 This judicial admission is critical. If parliamentary sovereignty has been “developed by the courts,” it cannot simultaneously be an independent, self-originating power. The judiciary, being subject to law itself, cannot grant an authority greater than that which it possesses or which is derived from the law it upholds.

The Common Law as the Ultimate Source of Authority

3.1 If the judiciary “developed” parliamentary sovereignty, and judicial officers are bound by the same law as everyone else, then the ultimate source of authority for state law must reside in the common law. The common law, embodying logic and reason applied to resolve disputes, predates Parliament and is the true foundation of legal authority.

3.2 The royal prerogative, which is the fountain of authority for Parliament’s creation and the mechanism for Royal Assent (e.g., the Royal Assent Act 1967), derives its authority from the common law. The Confirmation of the Charters 1297 explicitly defines the law by which the royal prerogative is bound as “the Common Law”.² This means that the very power enabling Parliament to enact statute law is derived from, and therefore subject to, the common law.

3.3 Therefore, by logical impossibility, statute law, being a product of the Crown in Parliament, cannot possess a greater authority than that which the Crown itself possesses, which is bound by the common law.

Legislation in law is an Equitable Claim by a Statutory Demand, Subject to Judicial Scrutiny for Lawfulness

4.1 Statute law, or legislation, is not binding outside of Parliament. It is “the highest form of law created by Parliament.”³ It is merely a second constraint on royal prerogative by consent between Parliament and the Crown.

4.2 The principle that “all are equal under the law and no one is above the law”⁴ dictates that legislation, as an act of governance, must be tested for its lawfulness by the independent judiciary.

4.3 Legislation, in this context, in law can only be understood as an equitable claim by a statutory demand by Parliament, which must be tested in the courts as to whether it is lawful. The hierarchy of law is therefore: the rules of equity, which follow the common law to ensure fairness and justice, which the courts can deem Acts of Parliament unlawful, but as the courts did not create statute law, the court cannot strike statute law down, and hence only parliament can repeal or amend statute law as they created it.

4.4 The rules of equity are supreme over the common law in cases of conflict, as legislatively codified common law in s 49 of the Senior Courts Act 1981.⁵ This statutory provision mandates that “wherever there is any conflict or variance between the rules of equity and the rules of the common law with reference to the same matter, the rules of equity shall prevail.”⁶ This means that the courts have a duty to apply the rules of equity to ensure justice, even if it means deeming an Act of Parliament “unlawful” in its application or effect.

4.5 Historically, Chief Justice Sir Edward Coke, in Dr Bonham’s Case, famously stated that “in many cases, the common law will control Acts of Parliament, and sometimes adjudge them to be utterly void [can only be interpreted in law as unlawful and hence void in law]: for when an Act of Parliament is against common right and reason, or repugnant, or impossible to be performed, the common law will controul it, and adjudge such Act to be void.”⁷ While the modern application of this principle has been debated, its underlying logic—that legislation must conform to reason and common right—remains a fundamental common law constitutional principle as common law precedent by definition is the logic and reason applied to resolve a dispute.

4.6 The Supreme Court, in R (Miller) v The Prime Minister; Cherry v Advocate General for Scotland (No 2), explicitly stated that “The Court, having orthodoxly described parliamentary sovereignty as the principle that ‘laws enacted by the Crown in Parliament are the supreme form of law in our legal system, with which everyone, including Government, must comply’ , stressed that this principle entails other principles demanding its efficacy.”⁸ The ratio decidendi of Miller (No 2) and Council of Civil Service Unions v Minister for the Civil Service (the GCHQ case)⁹ is that executive action must be rational and lawful, subject to judicial review. This logic, that governance must be rational and lawful, extends to the lawfulness of legislation itself, as Parliament is part of governance.

Constitutional Documents: Constraints on Parliament, Not Grants of Absolute Power

5.1 The constitutional documents of 1688/89, including the Bill of Rights 1689 and the Act of Settlement 1700, are not grants of absolute supremacy to Parliament. Instead, they are power-sharing agreements that codify common law principles and impose constraints on how royal prerogative to govern will be executed.

5.2 The Bill of Rights 1689 states that “noe Declarations Judgements Doeings or Proceedings to the Prejudice of the People… ought in any wise to be drawne hereafter into Consequence or Example.”¹⁰ This clause, derived from common law, means Parliament cannot act to the prejudice of the people’s ancient rights and liberties.

5.3 The Act of Settlement 1700 affirms that “the Laws of England are the Birthright of the People thereof and all the Kings and Queens who shall ascend the Throne of this Realm ought to administer the Government of the same according to the said Laws.”¹¹ This explicitly states that governance (legislative and executive authority) is subject to “the said Laws,” which are the people’s birthright and predate Parliament. It specifically does not say “govern according to statute law,” admitting the peoples birthright, the law is a higher, pre-existing legal framework. The “birthright” predates Parliament and automatically constrains Parliament unless consent is given.

5.4 The Crown and Parliament Recognition Act 1689, while confirming the validity of the Convention Parliament’s enactments, was specific to that Parliament and its irregularly convened nature.¹² It did not create a general, unconstrained authority for all future Parliaments to make or unmake law without being subject to the common law. Its purpose was to validate specific Acts, not to grant an unlimited power that would invert the established common law hierarchy.

5.5 Parliaments power to make or unmake law is strictly confined to its own creations, and hence one Parliament cannot bind a future Parliament, under the same principle of law that no individual can impose their will upon any other individual without consent.

Conclusion

6.1 The argument that parliamentary supremacy as the supreme creator of binding law is a myth created by the courts themselves is logically compelling and evidenced only from primary sources. Lord Hoffmann’s admission in Bancoult (No 2) confirms that this principle is a judicial development. This is not subject to secondary sources of people’s interpretation or opinions.

6.2 The common law, embodying logic and reason, is the ultimate source of authority, from which the royal prerogative derives and to which legislation is fundamentally subject. The hierarchy of law is therefore: the rules of equity (logic and reason applied to resolve disputes), which correct bad existing common law precedents, and which control statute law.

6.3 While Parliament creates statute law, this legislation in law is merely an equitable claim by Statutory Demand that must be tested in courts for its lawfulness against the common law and principles of equity, ensuring that all are equal under the law and no one is above the law.

6.4 The courts’ duty is to decide cases by this overarching law, ensuring that statute law is subject to the evolving truths created by logic and reason.
