How do they make laws consitional monarchy?

In a Constitutional Monarchy, laws are made entirely by a Parliament elected by the people.

The Monarch formally signs the acts of this parliament into law and would never withhold royal consent in doing this. Thus while all state power rests with the Monarch, the Monarch never uses these powers directly.

The Monarch is also the only power that can dissolve parliament (on the advice of ministers), triggering new parliamentary elections.
