The document discusses the justification for monarchies in modern constitutional governments. It argues that monarchies can play an important role in preventing absolutism by allowing different interests in society to participate in government. The document also discusses the concept of a monarch having reserve powers that can be exercised during times of crisis, such as a hung parliament, to stabilize democracy and constitutionalism. These reserve powers are meant to serve as a check on the government and save democracy in cases where other institutions are unable to function properly or deliver good governance.
