What are some disadvantages of a constitutional monarchy?

Answer 1

It depends entirely on how much power operates independently of the monarch. There are some constitutional monarchies like Morocco and Jordan, where the King has a few restraints and needs parliament's rubber stamp on some things, but primarily operates as an absolutist. There are other constitutional monarchies like Britain and Spain, where the King is effectively a remnant of the Ancien Régime and weilds no real power as concerns politics. And there are intermediate cases. The disadvantages of a constitutional monarchy derive directly from the type of constitutional monarchy that is being discussed.

In the Strong Monarch constitutional monarchy, some disadvantages are: (1) lack of popular consensus, (2) instability and inconsistency between rulers, (3) no rule of law for the King

In the Weak Monarch constitutional monarchy, the disadvantages are the same for any other democracy, such as: (1) indecisiveness of parliaments hold up the implementation of new laws, (2) short election cycles incentivize short term gains as opposed to long term benefits, (3) the King is an effective waste of taxpayer money because he does not do anything.
