KEY PRINCIPLES OF THE U.K. CONSTITUTION

The absolute and unlimited legal authority of parliament reflected in its ability to make, amend and repeal any law. 

'What parliament doth, no power on earth can undo'

It has power over: The absence of a codified constitution makes it the highest law, outranks common law, statute law, case law etc... Parliament cannot make laws that cannot be unmade. However, popular soverignity, the chance of public rebellion and E.U. law being questioned if its sovereign.

The principle that law should 'rule' in the sense that it applies to all conduct or behaviour and covers both private citizens and public officials. 

'Government of law and not a government of men'

An example of this is the Iraq War as they ignored the rule of law. So what is the rule of law? Everyone lives under law (police, politicians). The law is certain, predictable and equally, enforce and means there is justice

How important is it? It affects our everyday life and gives the ability for anyone to access justice (innocent till proven guilty). Equally as rich and poor get treated the same. 

In practice, the rich and powerful people get away with a lot of things. Examples: Margaret Thatcher's using the police as her private army and Tony Bliar and Iraq War
