The Nature and Sources Of The UK Constitution In A Level Politics | Everything You Need To Know

This video will explain the nature and sources of the UK Constitution, including its historical development and recent changes, crucial for A-Level politics. It will cover key specifications, potential essay questions, and debates, providing all the necessary knowledge and analytical points.

The UK Constitution is uncodified, meaning it's not a single document like the US Constitution, and unentrenched, allowing for easy changes with a simple parliamentary majority, making it flexible but vulnerable. It is traditionally unitary, with power centralized in the UK Parliament, though recent devolution has sparked debate on whether it remains truly unitary or has become a 'Union state' or 'quasi-federal'.

Parliamentary sovereignty, as coined by AV Dicey, means the UK Parliament is the supreme law-making and amending body, can legislate on any subject, cannot bind future parliaments, and its laws cannot be struck down by courts. The rule of law dictates that no one is above the law, including politicians and judges, and everyone is treated equally, with rights to fair trials and neutral judges.

The Westminster Model describes the UK's constitutional and governmental form, characterized by parliamentary sovereignty, the fusion of the executive and legislature (government members also being MPs), and centralized principal power.

Seven key historical documents shaped the UK Constitution: Magna Carta (1215) set out principles of liberty and due process; Bill of Rights (1689) included provisions for regular parliaments, free elections, and freedom of speech; Act of Settlement (1701) established Parliament's right to determine succession; Acts of Union (1707) united England and Scotland under one parliament, centralizing power; Parliament Acts (1911 and 1949) decreased the House of Lords' power, increasing democratization; European Communities Act (1972) confirmed UK's entry into the EEC, giving precedence to EU law; and the UK Withdrawal Agreement (2020) removed the UK from the EU, restoring parliamentary sovereignty. This gradual, organic development is unique due to the absence of a fundamental transformative change like a revolution.

The UK Constitution draws from five main sources: treaties (international agreements the UK has signed, making it partly codified and more entrenched, e.g., European Convention on Human Rights, UK Withdrawal Agreement); statute law (laws passed by Parliament, the most important source, making the constitution flexible due to simple majority requirements); authoritative texts (books explaining the political system, shaping behavior but not legally binding, e.g., AV Dicey's 'Law of the Constitution'); common law (legal principles laid down by judges in court cases that provide precedence, important for clarifying statute law); and conventions (unwritten customs and practices about government behavior, not legally binding but broadly accepted over time, e.g., individual ministerial responsibility, Royal assent, use of referendums).

Recent decades have seen a perceived decrease in parliamentary sovereignty due to EU membership (now reversed with Brexit), devolution of power to other bodies, and the Human Rights Act giving judges power to review legislation. The 2019 prorogation of Parliament case notably strengthened the principle of executive accountability to Parliament, with the Supreme Court ruling the prorogation unlawful and reinforcing the foundational principle of parliamentary sovereignty.
