The current dominant constitutional principle is parliamentary sovereignty, which means that parliament can make any law, there are no legal limitations on its legislative role. Therefore, the doctrine of parliamentary sovereignty is incompatible with a codified constitution, since a codified constitution would be the highest law. Furthermore, codified constitutions tend to arrive after a serious fracture has occurred in the political system of the country concerned; it is seen as a "new beginning". Not since the English Civil War of the 17th century has Britain experienced a serious breakdown in the political system; therefore there has never been a 'constitutional moment' in which the fundamental rules needed to be clarified and transcribed in a single document. One argument in favor of codification is that it would provide a clear and more accessible set of fundamental principles and rules. By collecting the fundamental rules of the Constitution in one place, it could facilitate people's understanding of the Constitution, with a potential educational effect. Furthermore, having a codified constitution could provide greater protection to the fundamental principles of democracy and the rule of law as they would be written and clear. Furthermore, codification could help resolve existing constitutional rules
