Constitution of the United Kingdom in the context of "Uncodified constitution"

A constitution, or supreme law, is the aggregate of fundamental principles or established precedents that constitute the legal basis of a polity, organization or other type of entity, and commonly determines how that entity is to be governed.

When these principles are written down into a single document or set of legal documents, those documents may be said to embody a written constitution; if they are encompassed in a single comprehensive document, it is said to embody a codified constitution. The constitution of the United Kingdom is a notable example of an uncodified constitution; it is instead written in numerous fundamental acts of a legislature, court cases, and treaties.

John (24 December 1166 – 19 October 1216) was King of England from 1199 until his death in 1216. He lost the Duchy of Normandy and most of his other French lands to King Philip II of France, resulting in the collapse of the Angevin Empire and contributing to the subsequent growth in power of the French Capetian dynasty during the 13th century. The baronial revolt at the end of John's reign led to the sealing of Magna Carta, a document considered a foundational milestone in English and later British constitutional history.

John was the youngest son of King Henry II of England and Duchess Eleanor of Aquitaine. He was nicknamed John Lackland (Norman: Jean sans Terre, lit. 'John without land') because, as a younger son, he was not expected to inherit significant lands. He became Henry's favourite child following the failed revolt of 1173–1174 by his brothers Henry the Young King, Richard, and Geoffrey against their father. John was appointed Lord of Ireland in 1177 and given lands in England and on the continent. During the reign of his brother Richard I, he unsuccessfully attempted a rebellion against Richard's royal administrators while the King was participating in the Third Crusade, but he was proclaimed king after Richard died in 1199. He came to an agreement with Philip II of France to recognise John's possession of the continental Angevin lands at the peace treaty of Le Goulet in 1200.

Constitutional monarchy, also known as limited monarchy, parliamentary monarchy or democratic monarchy, is a form of monarchy in which the monarch exercises their authority in accordance with a constitution and is not alone in making decisions. Constitutional monarchies differ from absolute monarchies (in which a monarch is the only decision-maker) in that they are bound to exercise powers and authorities within limits prescribed by an established legal framework. A constitutional monarch in a parliamentary democracy is a hereditary symbolic head of state (who may be an emperor, king or queen, prince or grand duke) who mainly performs representative and civic roles but does not exercise executive or policy-making power.

Constitutional monarchies range from countries such as Liechtenstein, Monaco, Morocco, Jordan, Kuwait, Bahrain and Bhutan, where the constitution grants substantial discretionary powers to the sovereign, to countries such as the United Kingdom and other Commonwealth realms, the Netherlands, Spain, Belgium, Denmark, Norway, Sweden, Lesotho, Malaysia, Thailand, Cambodia, and Japan, where the monarch retains significantly less, if any, personal discretion in the exercise of their authority. On the surface level, this distinction may be hard to establish, with numerous liberal democracies restraining monarchic power in practice rather than written law, e.g., the constitution of the United Kingdom, which affords the monarch substantial, if limited, legislative and executive powers.

The Constitution of Canada (French: Constitution du Canada) is the supreme law in Canada. It outlines Canada's system of government and the civil and human rights of those who are citizens of Canada and non-citizens in Canada. Its contents are an amalgamation of various codified acts, treaties between the Crown and Indigenous Peoples (both historical and modern), uncodified traditions and conventions. Canada is one of the oldest constitutional monarchies in the world.

The Constitution of Canada comprises core written documents and provisions that are constitutionally entrenched, take precedence over all other laws and place substantive limits on government action; these include the Constitution Act, 1867 (formerly the British North America Act, 1867) and the Canadian Charter of Rights and Freedoms. The Constitution Act, 1867 provides for a constitution "similar in principle" to the largely unwritten constitution of the United Kingdom, recognizes Canada as a constitutional monarchy and federal state, and outlines the legal foundations of Canadian federalism.

Parliamentary sovereignty is a longstanding concept central to the functioning of the constitution of the United Kingdom, but which is also not fully defined and has long been debated. Since the subordination of the monarchy under parliament, and the increasingly democratic methods of parliamentary government, there have been the questions of whether parliament holds a supreme ability to legislate and whether or not it should.

Parliamentary sovereignty is a description of the extent to which the Parliament of the United Kingdom has absolute and unlimited power. It is framed in terms of the extent of authority that parliament holds, and whether there are any sorts of law that it cannot pass. In other countries, a written constitution often binds the parliament to act in a certain way, but there is no codified constitution in the United Kingdom. In the United Kingdom, parliament is central to the institutions of state. The concept is exclusive to the UK Parliament and therefore does not extend to the Scottish Parliament, the Senedd and the Northern Ireland Assembly.

A convention, also known as a constitutional convention, is an uncodified tradition that is followed by the institutions of a state. In some states, notably those Commonwealth states that follow the Westminster system and whose political systems derive from British constitutional law, most government functions are guided by constitutional convention rather than by a formal written constitution. In these states, actual distribution of power may be markedly different from those the formal constitutional documents describe. In particular, the formal constitution often confers wide discretionary powers on the head of state that, in practice, are used only on the advice of the head of government, and in some cases not at all.

Some constitutional conventions operate separately from or alongside written constitutions, such as in Canada since the country was formed with the enactment of the Constitution Act, 1867. In others, notably the United Kingdom, which lack a single overarching constitutional document, unwritten conventions are still of vital importance in understanding how the state functions. In most states, however, many old conventions have been replaced or superseded by laws (called codification).

"No taxation without representation" is a political slogan that originated in the American Revolution, and which expressed one of the primary grievances of the American colonists for Great Britain. In short, many colonists believed that as they were not represented in the distant British parliament, any taxes it imposed on the colonists (such as the Stamp Act and the Townshend Acts) were unconstitutional and were a denial of the colonists' rights as Englishmen since Magna Carta.

The firm belief that the government should not tax a populace unless that populace is represented in some manner in the government developed in the English Civil War, following the refusal of parliamentarian John Hampden to pay ship money tax. In the context of British taxation of its American colonies, the slogan "No taxation without representation" appeared for the first time in a headline of a February 1768 London Magazine printing of Lord Camden's "Speech on the Declaratory Bill of the Sovereignty of Great Britain over the Colonies," which was given in parliament. The British government argued for virtual representation, the idea that people were represented by members of Parliament even if they didn't have any recourse to remove then if they were unsatisfied with the representation, i.e. through elections.
