Week 7 Parliamentary Sovereignty II: Challenges, Legislative Processes, and Constitutional Reform

The Human Rights Act $1998$ and Parliamentary Sovereignty

The Human Rights Act (HRA) $1998$ was designed to give domestic legal effect within the United Kingdom to the rights set forth in the European Convention on Human Rights (ECHR). Prior to this legislation, individuals seeking to rely on ECHR rights were often required to take their cases to the European Court of Human Rights in Strasbourg. Under the HRA $1998$, individuals can now rely on these rights directly within UK courts and tribunals. It is vital to distinguish between the European Union (EU) and the Council of Europe; they are distinct organizations, and the legal framework of the HRA $1998$ relates specifically to the Council of Europe's convention rights, which differs significantly from the mechanics of EU law.

Key provisions of the HRA include Section $2(1)$, which dictates that any court or tribunal determining a question related to a Convention right must "take into account" any judgment, decision, declaration, or advisory opinion issued by the European Court of Human Rights. Section $3(1)$ imposes a strong interpretive obligation, stating that, so far as it is possible to do so, both primary and subordinate legislation must be read and given effect in a way that is compatible with Convention rights. If a court finds it impossible to interpret primary legislation compatibly, Section $4(2)$ allows the court to issue a "declaration of incompatibility." Crucially, such a declaration is not legally binding on Parliament, meaning the legislation remains in force and the court cannot strike it down. This mechanism reflects a delicate balance between parliamentary sovereignty and the protection of human rights, as the final authority to change the law remains with the legislature.

Parliament has historically accepted the need for legal change almost every time a court issues a declaration of incompatibility under Section $4$. However, from a strictly legal standpoint, parliamentary sovereignty remains intact; Parliament can, if it chooses, legislate in contradiction to fundamental human rights principles. The constraints on such actions are considered political rather than legal. Lord Hoffmann, in the case of $ex \text{ p } Simms \text{ and } O'Brien$ [$1999$] UKHL $33$, articulated the "principle of legality," explaining that Parliament must squarely confront what it is doing and accept the associated political costs. Fundamental rights cannot be overridden by general or ambiguous wording; the intention to override such rights must be explicit.

Academic discussion, such as that by Elizabeth Adams in [$2021$], characterizes Section $4$ as a "double filter mechanism." In controversial cases, such as the prisoner voting saga, questions arise as to whether courts should issue multiple declarations of incompatibility on the same issue. While there were previous discussions regarding a British Bill of Rights to replace or amend the HRA, under the current Labour Government, these plans appear to have been abandoned.

The Impact of European Union Membership and the Principle of Supremacy

The United Kingdom's relationship with European Union Law presented significant challenges to the traditional Diceyan view of parliamentary sovereignty. Although the UK left the EU on $31$ January $2020$ at $11$ pm, the legal legacy of this membership remains a central case study in sovereignty. As a "dualist" state, the UK requires treaties ratified by the Government to be incorporated into domestic law via legislation before they can alter domestic laws. This was achieved through the European Communities Act (ECA) $1972$, which acted as a "pipe" for EU law to enter the UK legal system.

The ECA $1972$ established two primary mechanisms: Section $2(1)$ ensured that certain types of EU law, such as treaties and regulations, were directly applicable in the UK without further domestic legislation (the principle of direct effect established in $Van Gend en Loos$). Section $2(2)$ provided delegated powers for ministers to implement EU obligations, such as directives, through secondary legislation known as statutory instruments. The Court of Justice of the European Union (CJEU) established in $Costa \text{ v } Enel$ that EU law is supreme over the national law of member states. This supremacy contradicted Dicey’s tenet that no person or body has the right to set aside Parliamentary legislation and the principle that one Parliament cannot bind its successors, as later Parliaments were effectively restricted from legislating contrary to EU law.

A reconciliation between parliamentary sovereignty and EU law was attempted in the landmark case of $Factortame \text{ (No 2)}$. Lord Bridge argued that any limitation of sovereignty accepted through the ECA $1972$ was entirely voluntary. He maintained that it was the duty of UK courts to override national law in conflict with directly enforceable Community law because Parliament had intended this through the $1972$ Act. Consequently, Parliament retained sovereignty because it could, at any point, repeal the ECA $1972$ to regain full control, as eventually occurred with Brexit. While Professor Wade argued this represented a "constitutional revolution" where judges departed from traditional sovereignty without legal authority, others viewed it as a successful effort to harmonize two competing systems of supremacy.

Parliamentary Sovereignty and the Rule of Law

In the absence of a codified constitution, UK courts often adopt an "expansive approach" to parliamentary sovereignty to ensure it remains effective alongside the rule of law. This interpretation suggests that for sovereignty to function, individuals must have access to justice, legislation must receive authoritative judicial interpretation, and the government must remain accountable to Parliament. Courts will strive to interpret legislation in a way that is compatible with the rule of law, even when faced with "ouster clauses"—provisions intended to preclude judicial review of specific executive decisions.

Case law such as $Privacy International$ (and previously $Anisminic$) demonstrates the tension between the rule of law and parliamentary sovereignty, specifically regarding whether the Investigatory Powers Tribunal's decisions can be subject to judicial review. Similarly, in R \text{ (Evans) \text{ v } Attorney-General, involving the release of letters written by the then-Prince Charles to the government, the court found the Attorney-General's use of a veto power under Section $53$ of the Freedom of Information Act $2000$ to be unlawful. These cases illustrate that UK judges are prepared to interpret legislation narrowly to uphold fundamental aspects of the rule of law and prevent the executive from exercising unchecked power.

The Legislative Process and the Rise of the Executive

The legislative process in the UK involves the creation of primary legislation (Acts of Parliament) and secondary or delegated legislation. The development of policy and the drafting of major Bills are usually handled by the government, with specialist drafters in the Office of Parliamentary Counsel. For a Bill to become an Act, it typically must pass through the House of Commons and the House of Lords and receive Royal Assent. However, the Parliament Acts of $1911$ and $1949$ ensure the House of Lords cannot permanently veto legislation, only delay it.

An ideal legislative cycle begins with a Green Paper for consultation, followed by a White Paper detailing policy and a draft Bill. This is followed by pre-legislative scrutiny, parliamentary scrutiny, the passing of the Act, and eventually post-legislative scrutiny. Despite this structure, there are concerns regarding the "rise of the executive." Because the Government sits within the legislature and controls the Commons, it largely dominates the policy-making and drafting process. Furthermore, UK courts cannot judicially review Acts of Parliament, and modern legislation frequently confers broad discretionary powers upon the government to take executive action or create further rules.

Delegated Legislation and Constitutional Scrutiny

Secondary (or delegated) legislation is law created by ministers or other bodies under authority granted by a "parent" Act of Parliament. The most common form of this is the Statutory Instrument (SI). Parliament relies on delegated legislation because it lacks the time and resources to debate every technical or administrative detail (e.g., road traffic regulations or social security adjustments). It also allows for expert input and the flexibility to address unforeseen practical difficulties. Approximately $3,500$ SIs are made each year, though only about $1,000$ are typically considered by Parliament. Examples include the Motor Vehicles (Driving Licences) (Amendment) (No. $5$) Regulations $2025$ ($SI 2025/1085$) and the Immigration Skills Charge (Amendment) Regulations $2025$.

While primary legislation is immune to judicial review, delegated legislation is not. Courts can declare provisions within delegated legislation invalid if they exceed the powers granted by the parent Act or fail on other grounds of judicial review. However, the Hansard Society and various parliamentary committees have raised serious concerns about the current system. They argue that the powers granted to Ministers are often too broad, allowing them to make substantive policy decisions—such as creating criminal offences or infringing on rights—via SI with minimal scrutiny. Traditionally, SIs were for technical details, but this threshold has shifted.

Scrutiny is often deemed deficient because there is little correlation between the importance of an SI's content and the procedure used to review it. MPs may spend time on uncontroversial SIs while being unable to secure debates on significant ones. Most importantly, Parliament has no power to amend an SI; it is a "take it or leave it" scenario. This acts as a disincentive to scrutiny, as rejecting an instrument in its entirety is seen as a drastic step. Only $16$ SIs have been rejected since $1950$, and the House of Commons has not rejected one since $1979$, leading to a low-risk environment for ministers standing firm against opposition.

The Constitutional Role and Reform of the House of Lords

The House of Lords currently comprises approximately $800$ peers, none of whom are directly elected. The validity of its role was upheld in the case of $Jackson$, which confirmed the legality of the $1949$ Act and the removal of the Lords' veto power. The relationship between the two houses is further governed by the Salisbury-Addison convention, which dictates that the Lords will not vote down a policy contained in a government bill if that bill seeks to fulfill a manifesto commitment.

Recent historical reforms include the House of Lords Act $1999$ and the Constitutional Reform Act $2005$. However, the House of Lords in its current form is frequently described as indefensible in principle. Critics point to its size—it is the second largest parliamentary chamber in the world after China's National People's Congress—and the continued presence of $92$ hereditary peers representing landowning classes.

Proposed reforms vary based on the intended purpose of the chamber. If it is meant to restrain the government, an elected chamber is argued for; if the purpose is revision and scrutiny, other methods of composition might be justified. The Labour Commission on the UK's Future has recommended replacing the House of Lords with an "Assembly of the Nations and Regions." Current legislative efforts, such as the House of Lords (Hereditary Peers) Bill $2024-26$, updated as of $30$ September $2025$, aim to remove the remaining connection between hereditary peerage and membership of the House, abolish the jurisdiction related to hereditary claims, and make provision for resignation.
