Through United Kingdom, Statute and Anglo-Irish Treaty

The constitutional principles of parliamentary sovereignty, the rule of law, democracy and internationalism guide the UK's modern political system. The central institutions of modern government are Parliament, the judiciary, the executive, the civil service and public bodies which implement policies, and regional and local governments. Parliament is composed of the House of Commons, elected by voter constituencies, and the House of Lords which is mostly appointed on the recommendation of cross-political party groups. To make a new Act of Parliament, the highest form of law, both Houses must read, amend, or approve proposed legislation three times. The judiciary is headed by a twelve-member Supreme Court. Underneath are the Court of Appeal for England and Wales, the Court of Appeal in Northern Ireland, and the Court of Session for Scotland. Below these lie a system of high courts, Crown courts, or tribunals depending on the subject in the case. Courts interpret statutes, progress the common law and principles of equity, and can control the discretion of the executive. While the courts may interpret the law, they have no power to declare an Act of Parliament unconstitutional. The executive is headed by the Prime Minister, who must command a majority in the House of Commons. The Prime Minister appoints a cabinet of people who lead each department, and form His Majesty's Government. The King himself is a ceremonial figurehead, who gives royal assent to new laws. By constitutional convention, the monarch does not usurp the democratic process and has not refused royal assent since the Scottish Militia Bill in 1708. Beyond the Parliament and cabinet, a civil service and a large number of public bodies, from the Department of Education to the National Health Service, deliver public services that implement the law and fulfil political, economic and social rights.

Most constitutional litigation occurs through administrative law disputes, on the operation of public bodies and human rights. The courts have an inherent power of judicial review, to ensure that every institution under law acts according to law. Except for Parliament itself, courts may declare acts of any institution or public figure void, to ensure that discretion is only used reasonably or proportionately. Since it joined the European Convention on Human Rights in 1950, and particularly after the Human Rights Act 1998, courts are required to review whether legislation is compatible with international human rights norms. These protect everyone's rights against government or corporate power, including liberty against arbitrary arrest and detention, the right to privacy against unlawful surveillance, the right to freedom of expression, freedom of association including joining trade unions and taking strike action, and the freedom of assembly and protest. Every public body, and private bodies that affect people's rights and freedoms, are accountable under the law.

History

The history of the UK constitution, though officially beginning in 1800, traces back to a time long before the four nations of England, Scotland, Wales and Ireland were fully formed. Before the Roman Empire's conquest, Britain and Ireland were populated by Celtic migrants from the European continent, but ones who left no recorded history of law. Near the end of the Roman Republic in 55 and 54 BC, the former Consul and legion commander Julius Caesar invaded Britain during the broader Gallic Wars. This did not establish permanent occupation, as Caesar returned to Rome, became dictator and was assassinated. The Republic was transformed into an Empire, when Caesar's heir Augustus took power in 27 BC. In the reign of Augustus' grandson, Claudius, Britain was conquered from 43 AD. Under Rome's uncodified constitution, Roman Britain was administered by a governor, usually member of the Senate but appointed by the Emperor for their military record. Londinium was a provincial capital of 60,000 people, and Britain a cosmopolitan society of around 3 million people. Roman law was based upon a slave economy, and highly militarised. Hadrian constructed a wall from 122 as part of the Empire's limits, but this was soon moved north by Antoninus Pius from 142. Constantine the Great was stationed in York in 306 when he left to claim his title to be Emperor. Constantine marched on Rome under the cross in 312, and issued an Edict of Milan in 313. This triggered a series of events where the Church assumed more and more power over the law. But under constant assault, the Empire began to collapse and Britain was abandoned in 407. Neither the Theodosian Code issued in 438, nor the great Corpus Juris Civilis of Justinian I in 534 entered the laws of Britain. In the Dark Ages, during power struggles between Anglo-Saxons, Britons, Danes and Vikings, kings convened regular councils, called the Witan, composed of lords and church leaders. But it was not until the Norman Invasion of 1066 that one common law was established through England under one monarch.

Under William the Conqueror, advised by a King's Council (Curia Regis), the Domesday Book was compiled in 1086 cataloguing all land and labour to levy taxes. Just 12 per cent of people were free, while the feudal system made others serfs, slaves or bordars and cottars. In 1190 Richard the Lionheart, more closely tied with the Pope in Rome, joined the Third Crusade to invade the Holy Land, but at great cost. Taxes levied by Richard I, and his successor King John to pay for the wars led to intense discontent, and the aristocracy forcing the King to sign Magna Carta. This was a commitment to hold 'common counsel' before any taxation, hold courts at a fixed place, hold trials according to law or before an accused's peers, guarantee free movement of people for trade, and give back common land. Failure to abide by Magna Carta led to the First Barons' war, and the popular legend of Robin Hood emerged: a returned crusader who robbed from the rich to give to the poor. The commitments on common land were soon recast in the Charter of the Forest 1217, signed at St Paul's by Henry III. These documents established that the monarch, even with apparent authority from God, was bound by law, and it remains 'the nearest approach to an irrepealable "fundamental statute" that England has ever had.' Throughout the Middle Ages, common land was a source of welfare for common people, peasant labourers bound by a feudal system of control. In 1348, the Black Death struck England, and killed around a third of the population. As peasants lost their lords, and there was a shortage of workers, wages rose. The King and Parliament responded with the Statute of Labourers 1351 to freeze wage rises. This led to the Peasants' Revolt of 1381, where leaders demanded an end to feudalism, and for everything to be held in common. Despite the revolt's violent repression, slavery and serfdom broke down, yet most people remained without any substantial liberty, in political or economic rights. As sheep farming became more profitable than agricultural work, enclosures of common land dispossessed more people, who turned into paupers and were punished. Under Henry VIII, to seal a divorce from Catherine of Aragon and marry Anne Boleyn (who he soon beheaded for supposed infidelity), the Church of England was declared separate from Rome in the Act of Supremacy 1534, with the King as the head. The Law in Wales Act 1535 united Wales and England in one administrative system, while the King became ever more despotic, executing the Lord Chancellor, Sir Thomas More in 1535, and dissolving the monasteries and murdering those who resisted. After Henry VIII died, and power struggles following the death of his boy Edward VI at age 15, Elizabeth I, the daughter of Henry VIII and Anne Boleyn, took the throne in 1558. Half a century of prosperity followed as Elizabeth I avoided wars, but founded corporations including the East India Company to monopolise trade routes. Under her successor, James I, further companies were created to colonise North America, including the London Company and the Virginia Company in 1606, and the Massachusetts Bay Company in 1628. Many religious dissidents left England to settle the new world.

While Elizabeth I maintained a Protestant church, under her successor James, who unified the Scottish and English Crowns, religious and political tensions grew as he asserted a divine right of Kings. This prompted a series of cases from Sir Edward Coke, the Chief Justice of the Common Pleas and then King's Bench courts, which denied that the King could pass judgment in legal proceedings, and held that the royal prerogative was subject to the law and cannot be expanded. Coke CJ went even further in Dr Bonham's case, holding that even that "the common law will control Acts of Parliament". Though supported by some judges, the idea that common law courts could nullify Acts of Parliament was rejected, and the common law was formally placed under the King's control in the Earl of Oxford's case, establishing that equity (then administered by the Lord Chancellor in the House of Lords) was above common law. Coke fell from favour, and was removed from judicial office. When Charles I succeeded to the throne in 1625, and more fervently asserted a divine right, including the ability to levy tax without Parliament, Coke and others presented the Petition of Right 1628. This demanded the King to abide by Magna Carta, levy no tax without Parliament, not arbitrarily commit people to prison, not have martial law in times of peace, and not billet soldiers in private homes. Charles I responded by shutting down or proroguing Parliament and taxing trade (or "ship money") without authority. The country descended into the English Civil War in 1642 culminating in the capture and execution of King Charles I on Whitehall in 1649 by the New Model Army led by Oliver Cromwell. Cromwell, not wishing to become a king, became a de facto dictator. After his death, the monarchy was restored with Charles II in 1660, but his successor James II again attempted to assert divine right to rule. In 1688, Parliament 'invited' a replacement King and Queen, William and Mary of Orange, and after a brief conflict forced James II out. Known as the Glorious Revolution, Parliament proclaimed a new Bill of Rights 1689, with a Claim of Right Act 1689 in Scotland, that cemented parliamentary sovereignty. As well as reaffirming Magna Carta, it says the 'pretended power of suspending laws or the execution of laws by regal authority without consent of Parliament is illegal', that 'election of members of Parliament ought to be free', and that 'Parliament ought to be held frequently'. The justification for government itself, encapsulated by John Locke in his Second Treatise on Government was the protection of people's rights: "lives, liberties and estates."

With parliamentary sovereignty as the cornerstone of the new constitution, Parliament proceeded to set up a system of finance in the Bank of England Act 1694 and the Act of Settlement 1700 created an independent system of justice: judges were salaried and could not be removed except by both Houses of Parliament, no member of the House of Commons could be paid by the Crown, and the Crown had to be Anglican. In 1703, Ashby v White established that the right to vote was a constitutional right. The Act of Union 1707 formally joined the parliaments of England and Scotland, by giving Scottish electors representation in Westminster. The new union was soon faced with disaster as in the War of the Spanish Succession, the Spanish promised the right for British ships to trade (mostly slaves) in the seas around South America. The South Sea Company, duly incorporated to monopolise trade routes, became the object of mass financial speculation, provoked by government ministers interested in its rising share price. When it transpired, contrary to promoters' stories, that no trade was done because the Spanish had revoked their promise the stock market crashed, driving economic chaos. This was made worse by the decision of conservative politicians to endorse the company to take over the national debt as an alternative financier to the government over the Whig dominated Bank of England. The result of the crash was that the Chancellor of the Exchequer was imprisoned in the Tower of London for his corruption, the Postmaster General committed suicide, and the disgraced Lord Chancellor was replaced with Lord King LC who promptly ruled that people in a position of trust must avoid any possibility of a conflict of interest. Out of the chaos, Robert Walpole emerged as a stable political figure who for 21 years held a majority of the House of Commons, and is now considered the first "Prime Minister". In 1765, Entick v Carrington established that the government could do nothing but that which was empowered by law, while the first teacher of English law, William Blackstone represented the standard view in his Commentaries on the Laws of England that slavery was unlawful and that "the spirit of liberty is so deeply ingrained in our constitution" any person enslaved in England must be freed. However, the transatlantic slave trade had accelerated to North American colonies. In 1772, when Lord Mansfield ruled in Somerset v Stewart that slavery was unlawful at common law, this set off a wave of outrage in southern, enslavement colonies of America. Together with northern colonies grievances over taxation without representation, this led to the American Revolution and Declaration of Independence in 1776. The British military failed to hold control. Instead, it began settling Australia from 1788. In 1789, the French Revolution broke out, and the King was deposed with demands for "liberty, equality and fraternity". The British aristocracy reacted with repression on free speech and association to forestall any similar movement. While figures like Jeremy Bentham called natural rights "nonsense upon stilts", Mary Wollstonecraft called for A Vindication of the Rights of Woman as well as men, arguing that unjust gender and class oppression flowed from "the respect paid to property... as from a poisoned fountain". While successful in the Napoleonic wars in defeating France, and cementing union with Ireland in the Act of Union 1800, liberty, freedom and democracy were scarcely protected in the new "United Kingdom".

During this time, with the invention of the steam engine the industrial revolution had begun. Poverty had also accelerated through the Speenhamland system of poor laws by subsidising employers and landowners with parish rates. The Corn Laws from 1815 further impoverished people by fixing prices to maintain landowner profits. While the Great Reform Act 1832 extended the vote slightly, only those with property had any representation in Parliament. Although the Slavery Abolition Act 1833 abolished the slave trade within the British Empire, it only compensated slave owners and made ex-slaves in colonies pay off debts for their freedom for decades after. With the Poor Law Amendment Act 1834, further punishment for poverty was inflicted as people were put into workhouses if found to be unemployed. In R v Lovelass a group of agricultural workers who formed a trade union were prosecuted and sentenced to be transported to Australia under the Unlawful Oaths Act 1797, triggering mass protests. A movement called Chartism grew demanding the right to vote for everyone in free and fair elections. As the great famine hit Ireland and millions migrated to the United States, Chartists staged a mass march from Kennington Common to Parliament in 1848 as revolutions broke out across Europe, and the Communist Manifesto was drafted by German revolutionary Karl Marx and Manchester factory owner Friedrich Engels. While the Crimean War distracted from social reform and Viscount Palmerston opposed anything, the American Civil War of 1860 to 1865 ended slavery in the US, and the UK gradually enabled greater political freedom. In the Second Reform Act 1867 more middle-class property owners were enfranchised, the Elementary Education Act 1870 provided free primary school, and the Trade Union Act 1871 enabled free association without criminal penalty. The Representation of the People Act 1884 reduced the property qualification further, so that around one third of men could vote. Still, outside the UK, liberty and the right to vote were violently repressed across the vast British Empire, in Africa, India, Asia and the Caribbean.

From the start of the 20th century, the UK underwent vast social and constitutional change, beginning with an attempt by the House of Lords to suppress trade union freedom. In response, the labour movement organised to support representatives in Parliament, and in the 1906 general election won 29 seats and supported the Liberal Party's programme of reform. This included a legal guarantee of the right of unions to collectively bargain and strike for fair wages, an old-age pension, a system of minimum wages, a People's Budget with higher taxes on the wealthy to fund spending. After a further election brought by the House of Lords blocking reform, Parliament pass a National Insurance system for welfare, and the Parliament Act 1911 prevented the House of Lords blocking legislation for more than two years, and removed the right to delay any money bills. Despite this, the Liberal government, against the opposition of Labour, armed for and entered World War I. At the end of the War, with millions dead, Parliament passed the Representation of the People Act 1918 which enabled every adult male the vote, although it was only after the mass protest of the Suffragettes that the Representation of the People (Equal Franchise) Act 1928 enabled all women to vote, and that the UK became democratic. The War also triggered uprising in Ireland, and an Irish War of Independence leading to the partition of the island between the Republic of Ireland in the south and Northern Ireland in the Government of Ireland Act 1920. The Versailles Treaty at the end of the War demanded German reparations, beggaring the country through the 1920s and upon the Great Depression leading to a fascist collapse under Hitler.

The failed international law system, after World War II was replaced with the United Nations where the UK held a permanent seat on the UN Security Council. However the British Empire began to crumble as India and nations across Africa fought for democracy, human rights, and independence. To prevent any recurrence of the Holocaust and war, the Council of Europe was established to draft the European Convention on Human Rights in 1950. Further, it was seen that the only way to prevent conflict was through economic integration. The European Economic Community, which became the European Union in 1992, was supported by Winston Churchill with the UK to be "at the centre", although it did not enter until the European Communities Act 1972. Under Margaret Thatcher, significant cuts were made to public services, labour rights, and the powers of local government, including abolishing the Greater London Council. However, some powers were restored with extensive devolution of power in the Scotland Act 1998, Northern Ireland Act 1998, Greater London Authority Act 1999 and the Government of Wales Act 2006. After many years of armed conflict in Northern Ireland, the Good Friday Agreement of 1998 brought peace. The Human Rights Act 1998 empowered courts to apply Convention rights without the need for claimants to take cases to the Strasbourg court. The House of Lords Act 1999 reduced but did not fully eliminate hereditary peers. Since a financial crisis of 2007–2008 brought about by bankers' speculation, a Conservative and Liberal Democrat coalition launched a programme of "austerity" cuts, and cemented their term in the Fixed-term Parliaments Act 2011. After 2015, however, early elections were held anyway in 2017, following a referendum on EU membership that resulted in 51.9 per cent of people favouring to leave, and 48.1 per cent of voters favouring to remain. The United Kingdom formally left the European Union on 31 January 2020.
