Smaller house of parliament.
500 seats using mixed member proportional representation.
Sometimes more due to overhang seats.
Elected in votes every four years (at predetermined times).
The 250 seats allocated to allow for proportional representation are appointed from party lists. These party lists are subject to stringent rules as to who can go on them.
Age and experience outside of politics, academia, and the media are emphasised. As such party list members must be at least 30 years old and hold a post-graduate qualification in a numerical subject.
500 seats allocated to any adult (>=18 years old) citizen on a random basis every two years. The intention is to provide a house that accurately reflects the views of normal people.
The People's house reviews legislation and can veto any bill passed to it by the Party House, if a bill is passed back in this manner then the Party House can override with a two thirds majority.
