The UK Parliament is based on the principle of parliamentary Sovereignty. The Parliamentary Sovereignty is the most important feature of the UK Constitution. The Parliament is the supreme legal authority in the UK and it can change, create or destroy a law. The Courts do not have the power to overrule the legislations of the Parliament. No Parliament can make a Law that cannot be changed by a later Parliament because Laws are made in accordance with the relevant time and necessity.
The UK Constitution and the Parliamentary Sovereignty
Although it is known that the Constitution is unwritten, it is not completely true. The UK Constitution is not written in huge texts like that of USA or Germany but most of it are written from the laws passed in the Parliament and known as “Statute Laws”. Thus the UK Constitution is known as a partly written and wholly codified Constitution.
Growths affecting Parliamentary Sovereignty
Down the years, the UK Parliament has passed laws that have itself put limitations to parliamentary Sovereignty. These are laws that reflect political situations both within and outside UK.
The Scottish Parliament and the Welsh Assembly to which power has been devolved by the UK Parliament.
Human Right Acts of 1998
The entry of UK in the European Union in 1972
The decision to set up a Supreme Court in UK by 2009, which will end the function of the House of Lords as the apex court of the country.
However, in reality, the Parliament can repeal any Law that implement changes.
