There's a lot of questions on Politics.SE asking if the queen has any decision-making power:
Did the supreme court overrule the monarch?
Can the Queen of the United Kingdom appoint her successor?
Could the Queen overturn the UK Supreme Court ruling regarding prorogation of Parliament?
What governmental power does the Monarch hold in Great Britain?
The actual purview of Her Majesty The Queen's prerogative?
Did the supreme court overrule the monarch?
Can the Queen refuse to suspend the Parliament?
Could the Queen have stopped Brexit?
Can the Queen still cancel Brexit?
What power does the Queen have in the event of a Hung Parliament?
If the elected UK parliament falls into disarray, can the reigning monarch take over?
What kind of legislative power does the British monarchy possess?
Why don't British kings and queens veto laws?
All of them could be closed as duplicates of a single canonical question explaining that the Queen has no personal decision-making authority. Does Meta agree? If so, should we create a new canonical question or reuse an existing one?
