The surprising fact is that royal assent to legislation has only been refused once since 1708, which sounds reassuring until you notice the power still legally exists. The monarch formally appoints the prime minister, dissolves Parliament, and can refuse bills, and none of that requires anyone's consent. In 1975 a governor-general dismissed Australia's elected government, showing convention is not a safeguard. My opponent will probably say the Crown is purely ceremonial now. But democracy shouldn't depend on an unelected family choosing to keep being ceremonial. That's the drag: real power resting on goodwill rather than consent.
