Understanding The Uk Constitution: Its Functions And Purpose

The UK constitution is a set of rules and principles that govern the country and outline the functions of its institutions and the rights and duties of its citizens. Unlike many other countries, the UK does not have a single written or codified constitutional document. Instead, its constitution is spread across various sources, including specific Acts of Parliament, judicial decisions, conventions, and treaties. This dispersal can make the UK constitution more challenging to understand, but it also offers flexibility and adaptability. The UK constitution has evolved over hundreds of years and is characterised as monarchical, supreme, largely unwritten, and flexible. It enshrines rights and fair labour standards and holds executive power and public bodies accountable under the law.

The UK constitution is largely written but uncodified

The UK constitution is often described as 'unwritten', but this is not entirely accurate. While the UK does not have a 'written' or 'codified' constitution in the traditional sense of a single document, it does have a constitution that is spread across various sources. This dispersal can make it more challenging to identify and understand.

The UK's constitution can be found in specific Acts of Parliament, such as the Bill of Rights 1689, the Acts of Union 1707 and 1800, and the Human Rights Act 1998. It also includes constitutional conventions, which are understandings of how the system should operate, such as the monarch acting on ministerial advice and the Prime Minister sitting in the House of Commons. Additionally, judicial decisions and treaties play a role in shaping the UK's constitution.

The lack of a codified constitution in the UK means that there are no special procedures for amending it. A 'constitutional statute' can be repealed or amended by a simple majority vote in Parliament, unlike in countries with entrenched constitutions, such as the United States. This flexibility has enabled significant changes, such as the introduction of the Human Rights Act and devolution to Scotland, Wales, and Northern Ireland. However, it also means that the UK constitution is more susceptible to frequent changes by the government of the day.

The main disadvantage of an uncodified constitution is its complexity and the ease with which it can be amended compared to codified constitutions with elaborate amendment procedures. On the other hand, this flexibility has allowed for various reforms, as previously mentioned. In the absence of a codified constitution, Parliament acts as the ultimate guardian of the UK's constitution.

Parliamentary sovereignty

The UK constitution is often described as "unwritten" or "uncodified", meaning that it is not contained in a single document. Instead, it is spread across various sources, including specific Acts of Parliament, constitutional conventions, and judicial decisions. This makes the UK constitution different from those of many other countries, which typically have a written or codified constitution.

One of the key features of the UK constitution is the principle of parliamentary sovereignty, which means that Parliament is the supreme law-making body. Parliamentary sovereignty implies that Parliament has the power to make or unmake any law without being limited by a constitutional text. This means that a 'constitutional statute' can be repealed or amended by a simple majority vote in Parliament, unlike in countries with entrenched constitutions, such as the United States, where additional requirements must be met to amend the constitution.

The UK's parliamentary sovereignty has evolved over time, with power shifting away from the monarch and towards Parliament and the prime minister. For example, the Petition of Right, asserted by Parliament in the 17th century, prevented the monarch from imposing taxation without Parliament's consent, and the Habeas Corpus Act 1640 denied the monarch the power to arrest people for failing to pay taxes. Today, while the monarch remains the official "head of state", all prerogative power is exercised by the prime minister, subject to judicial review.

The flexibility of the UK's uncodified constitution has allowed for significant changes to be made, such as the removal of hereditary peers from the House of Lords, the introduction of the Human Rights Act, devolution to Scotland, Wales, and Northern Ireland, and the creation of the Supreme Court. However, some argue that a codified constitution would provide greater clarity and stability, and efforts have been made to explore options for reform.

Constitutional conventions

The UK's constitution is different from that of many other countries in that it is largely unwritten and uncodified, meaning that it is spread across various sources and is not contained in a single legal document. This makes it harder to understand and identify.

While some conventions are well-established and widely accepted, others may be more contested or ambiguous. Some conventions may also change over time as political practices and norms evolve.

The UK's constitutional conventions are often codified in documents such as the Cabinet Manual. This helps to provide a record of these important agreements and procedures, even if they do not carry the same legal weight as statutes or laws.

The flexibility of the UK's uncodified constitution means that it can be relatively easily amended or adapted to changing circumstances. This has allowed for significant reforms such as the introduction of the Human Rights Act and devolution to Scotland, Wales, and Northern Ireland.

Judicial independence

The UK constitution is largely written but uncodified, meaning that while it exists, it is not contained in a single document. Instead, it is spread across various sources, including specific Acts of Parliament, understandings of how the system should operate (constitutional conventions), and decisions made by judges (judicial decisions).

The UK's constitution also includes the principle of parliamentary sovereignty, which means that Parliament is the ultimate guardian of the constitution and can make or unmake any law without being limited by a constitutional text. This means that a 'constitutional statute' can be repealed or amended by a simple majority vote in Parliament, making the UK constitution relatively easy to amend compared to countries with codified constitutions.

The executive branch of the UK government, led by the Prime Minister, is subject to judicial review, further emphasising the importance of judicial independence. The judiciary's role in interpreting and applying the law ensures that executive power and public bodies are held accountable under the law.

In practice, constitutional principles emerge through cases of judicial review. Any public body or private body exercising public functions can be the target of judicial review, including government departments, ministers, and the Prime Minister. Individuals can challenge the decisions of these bodies if they have a "sufficient interest" within three months of the grounds for the cause of action becoming known.

Overall, the dispersal of the UK's constitution across various sources, including judicial decisions, and the principle of parliamentary sovereignty, allow for flexibility and adaptability in the country's governance. The independence of the judiciary, protected by the Constitutional Reform Act, plays a crucial role in upholding the rule of law and ensuring accountability within the UK's constitutional framework.

The UK's constitutional history

The UK's constitution is unique in that it is largely unwritten and uncodified, meaning that it is spread across various sources, including Acts of Parliament, judicial decisions, and conventions, rather than being contained in a single document. This is because the UK has not experienced any major historical turning points, such as revolutions or invasions, that would have necessitated a complete overhaul of its constitutional framework.

Over time, the power of the monarchy was gradually curtailed in favour of a more democratic system of government. The Petition of Right, asserted by Parliament in the 17th century, prevented the monarch from imposing taxation without Parliament's consent, and the Habeas Corpus Act 1640 denied the monarch the power to arrest people for failing to pay taxes. The English Civil War and the execution of Charles I further solidified the settlement of power in the Bill of Rights 1689.

The Act of Union 1707, which united England and Scotland into the Kingdom of Great Britain, and the Act of Settlement 1701, which established the succession of the Hanoverian dynasty, were also significant milestones in the development of the UK's constitution. The emergence of Robert Walpole as the first prime minister during this period further shaped the constitutional landscape.

In more recent times, the UK's constitution has continued to evolve, with the introduction of statutes such as the Human Rights Act 1998, the Scotland Act, the Northern Ireland Act, and the Government of Wales Act 1998, which have devolved power to Scotland, Wales, and Northern Ireland, and established their respective legislative bodies. The Constitutional Reform Act 2005 also played a significant role in safeguarding judicial independence by establishing the Judicial Appointments Commission.

While the UK's uncodified constitution has been criticised for its complexity and lack of a clear framework, it has also been praised for its flexibility and adaptability, allowing for relatively easy amendments and reforms to meet the changing needs of the country.
