I mean you do know the monarchy has a fuckton of power it can legally use? Like when the Queen dismissed a Prime Minister and his government in Australia?
Let me expand on that for you. The
only legal powers that the British Monarchy has over Australia is the ability to dissolve the Parliament and to force the Prime Minister to step down in times of constitutional crisis.
Dissolution is the term used for the action of ending a Parliament or a House of the Parliament. Under the Constitution only the Governor-General has the power to take such action. By convention the Governor-General takes this action only on the advice of the Prime Minister of the day.
The Governor General, His Majesty the King's representative in Australia. may legally dissolve the Senate (the upper house of Parliament) at any time
but only after receiving the request of the Australian Prime Minister to do so. In very limited circumstances under the Constitution the Governor General may perform a Double Dissolution, dissolving both the Senate and the lower house (the House of Representatives). This has happened once in Australia's history.
Dissolution does not happen for shits and giggles. It happens when the Senate and the House of Representatives are deadlocked and unable to function for months. The 'trigger' to do this is very strictly laid out in the Constitution. The Prime Minister can
only request that the Governor General perform a Dissolution if the 'trigger' is strictly met, and the Governor General can
only perform a Dissolution upon receiving this request. Once Dissolution is carried out, elections are held.
So technically yes, HRM can dissolve the Parliament, but only when requested by the Prime Minister, and only in extraordinary circumstances.
There is a second power that the Governor General has, and that is to force the serving Prime Minister/Premier to step down, but that can only be used when either the Prime Minister/Premier has completely lost the backing of his party but is refusing to step down, or else when the Prime Minister/Premier is refusing to request a Dissolution even though the 'trigger' has been met. Then the Governor General will then nominate a caretaker Prime Minister/Premier and elections are held immediately.
HRM
cannot walk into Parliament House and say "Bugger off the lot of yers, yer bogans". He has to be asked to do so nicely by the Prime Minister. He
can remove a Prime Minister and appoint a caretaker Prime Minister in his stead, but again, this can only be done within strict constitutional guidelines, and it's really just to save the Senate the hassle of calling the coppers and having the Prime Minister-in-name-only removed from the building by force.
