Act of Parliament (UK). An Act of Parliament is a statute enacted as primary legislation by the sovereign legislature of the United Kingdom, the Parliament of the United Kingdom. It represents the highest form of law within the British constitution, capable of creating, amending, or repealing any legal rule, and no court can declare an Act invalid. The authority of Parliament to make such law is often summarized by the constitutional principle known as parliamentary sovereignty.

Definition and legal status

An Act of Parliament is a formal written enactment passed by the House of Commons, the House of Lords, and receiving Royal Assent from the Monarch of the United Kingdom. Its legal status is supreme within the British constitution, a principle famously articulated by constitutional theorist A. V. Dicey. This supremacy means that no other body, including the judiciary, can strike down or refuse to apply an Act. This doctrine was historically challenged only by laws from the European Union under the European Communities Act 1972, a position altered by the European Union (Withdrawal) Act 2018. Acts can alter fundamental constitutional arrangements, as seen with the Acts of Union 1707, the Parliament Acts 1911 and 1949, and the Scotland Act 1998.

Legislative process

The process for creating an Act, known as the legislative process, begins with a proposal presented as a Bill. Most government Bills are introduced in the House of Commons by ministers like the Prime Minister or the Chancellor of the Exchequer, following approval by the Cabinet of the United Kingdom. The Bill undergoes several readings and committee stages in each House, with detailed scrutiny often occurring in the House of Commons Public Bill Committee. The Parliament Acts 1911 and 1949 allow the House of Commons to bypass the House of Lords under certain conditions, as occurred with the War Crimes Act 1991. Final approval is signified by Royal Assent, last withheld by Queen Anne in 1708.

Types of Acts

Acts are categorized by their subject matter and scope. Public general acts apply to the general law of the land, such as the Human Rights Act 1998 or the Equality Act 2010. Local and personal acts, now rare, address specific localities, corporations, or individuals, like those enabling major infrastructure projects historically overseen by the London County Council. Private acts confer particular powers or benefits on individuals or entities. Hybrid bills combine elements of both public and private bills, such as the legislation for the High Speed 2 railway. Financially, a Consolidated Fund Act authorizes government expenditure, while a Finance Act implements the budget set by the Chancellor of the Exchequer.

History and development

The evolution of Acts traces from medieval royal assent to written statutes. Key historical statutes include Magna Carta (1215), the Bill of Rights 1689, and the Act of Settlement 1701. The Parliament Acts 1911 and 1949 fundamentally altered the relationship between the House of Commons and the House of Lords, restricting the latter's power. The European Communities Act 1972 marked a significant shift by incorporating European Union law into domestic law, a process reversed by the European Union (Withdrawal) Act 2018. The Human Rights Act 1998 incorporated the European Convention on Human Rights, while devolution Acts like the Scotland Act 1998 and the Government of Wales Act 2006 created the Scottish Parliament and the Senedd.

Application and interpretation

Once enacted, the application and interpretation of an Act is the responsibility of the courts. Judges in the Supreme Court of the United Kingdom, the Court of Appeal, and other senior courts apply rules of statutory interpretation to ascertain Parliament's intention. The traditional approach includes the literal rule, the golden rule, and the mischief rule, but modern practice, influenced by the Human Rights Act 1998, favors a purposive approach. Landmark interpretive cases include those concerning the Dangerous Dogs Act 1991 and the Official Secrets Act 1911. The Law Commission often recommends consolidating or repealing obsolete Acts.

Relationship with other laws

Acts of Parliament sit at the apex of the UK legal system, superseding all other domestic sources including common law, equity, and delegated legislation made by bodies like the Privy Council or Secretary of State. The relationship with international law is dualist; treaties like the European Convention on Human Rights require an Act, such as the Human Rights Act 1998, to have domestic effect. Following Brexit, the relationship with European Union law is governed by the European Union (Withdrawal) Act 2018. In devolved nations, Acts of the Scottish Parliament or the Senedd are subordinate to Acts of Parliament, as established by the Scotland Act 1998 and confirmed by cases like R (Miller) v Secretary of State for Exiting the European Union.
