That's the problem with these legal fictions. It is the sovereign's will, but ,of course she exercises it only in accordance with the advice she receives.......from the executive.! The English civil war estabished that parliament was sovereign,so no oversight required! Now, is parliament sovereign or does PM really rule?It’s the Executive’s will. The Executive argued the Queen had no choice therefore there is no remedy for an Executive if it wishes to suspend Parliament for six months, a year or whatever. As there is no effective remedy the court may wish apply one.
The Queen’s problem is that she has no oversight function or power over the Executive as Head of State so all this calls into question what is the Monarch for and would we be better served with an elected Head of State with oversight powers.
Not sure about elected head, more that these constitutional issues need sorting....see Gough Whitlam removal. Don't think my master plan for a federal republic of Britain will be adopted any time soon.
