The word 'democracy' is derived from ancient Greek and means, literally, 'rule by the people'. The system of State government in Western Australia is parliamentary democracy broadly based on the British Westminster model. There are three arms of government; the Parliament (the legislature), the Executive, and the Judiciary. Under this system the people of the State elect the legislature (the Members of Parliament) and from them an Executive (the Ministry) is formed. The Executive is responsible for proposing, implementing and administering the laws passed by Parliament and is accountable to the Parliament for it actions. Ours is, therefore, a democratic system because government derives its authority from the people through an elected Parliament.
