In any system of government conducted by elected representatives of the people, the relationship between the representative assembly holding the legislative power and the holders of the executive power is of great significance. In a parliamentary system, in which the executive is formed out of the legislative assembly, the relationship is of greater significance. In such a system the executive, the ministry, is supposed to be scrutinised and controlled by the legislature. In practice, in most systems inherited from the United Kingdom, the ministry has come to control the lower house of the legislature through control of disciplined and hierarchical parties. In this situation, as has been observed in Chapter 1, the role of a second chamber like the Senate is crucial, and its relationship with the executive must, if it can, compensate for the usual ministerial dominance of the lower house.
