The reason that the Conservative Libertarian Party of the United Kingdom (TCLP-UK) has in its Constitution the provision that the Monarchy should be put to a referendum of all 21 year adults once every 21 years is that unless the State is revamped from time to time to reflect the priorities of the next generation, long-term maliase sets in in the functioning of the State. Out with the old and in with the new is thus the fundamentals of democracy wherein the State has a fresh chance to assess and provide the structure and functioning of society.
This happens in Parliamentary Democracy in the United Kingdom when there is a general election once every five years or sooner if the Prime Minister of the day needs fresh mandate in light of political imperatives. But that is not enough. The Constitution needs to respond to the needs of the next generation and within that Parliamentary democracy should function.
TCLP-UK is not a Republican movement in the strictest defininition of the term for cultural tradition of the United Kingdom should be adhered to as the culture is what the country projects to the wider humanity so that people across the world knows who they are dealing with when it comes to business and tourism both into the country and internationally.
Every Monarch should have the right to the provision that he or she manages Parliamentary Democracy with as much or as little interference that the Monarch sees as being necessary as the Head of State whose prime responsibility is the need to look after the State. Some Monarchs exert more powers and others less. It is not for the Courts to decide what these should be. If a Monarch is acting dictarorially the next generatlon will have the chance to dismiss him or her in the national referendum and the next in line to the throne will then come into the position as Head of State.
This is how the State gets revamped and maiaise is avoided. When there are unlimited tenures for the Monarch, the State is hindered from nationalism and patriotism ceases in the individual citizens who become subjects to the Monarch. This causes conflicts for differnt generations place different emphasis on how much freedom they should like to have, the rights that they should enjoy, and so forth.
