A Constitution is a set of fundamental principles and procedures, agreed to by the people or their representatives which form the baisis of government. For example, a constitution will usually contain basic powers a government can use - while detailing what rights a citizen of that country has. In the UK, we have an uncodified constitution. An uncodified constitution means that it isn't necessarily written out in full and has many different sources. These sources are: - Works of Authority - these are textbooks written by academics and parliamentarians. For example, a cornerstone of the British Parliament is a book known as Eskine May after its author. - Common Law - these are judgements made by judges in cases which are used as precidant for future decisions. For example, the crime of Murder is a common law judgement - its illegality doesn't derrive from an act of Parliament. - Acts of Parliament - these are laws passed by Parliament and in some cases the European Parliament. These are not special laws, they are just standard acts of Parliament and can be changed by the same procedures as all other acts. For example, the Human Rights Act 1998 which includes the European Convention on Human Rights into UK law is seen as being constitutionally signnificant. - Tradition and convention - these derrive their power on the basis that we do them because we always have. For example, the power of the Monarch is largely derrived from tradition. - The Royal Perogative - Although the Monarch agrees to abide by the Constitution in the UK, they are able to exercise some powers as head of state. However, over time these have been passed to the Prime Minister (Head of Government) to exercise. For example, the right to go to war.
