Organs of government

Where a federation has a bicameral legislature the upper house is often used to represent the component states while the lower house represents the people of the nation as a whole. A federal upper house may be based on a special scheme of apportionment, as is the case in the senates of the United States and Australia, where each state is represented by an equal number of senators irrespective of the size of its population.

Alternatively, or in addition to this practice, the members of an upper house may be indirectly elected by the government or legislature of the component states, as is the case in the German Bundesrat. The lower house of a federal legislature is usually directly elected, with apportionment in proportion to population, although states may sometimes still be guaranteed a certain minimum number of seats.

In Canada, the provincial governments represent regional interests and negotiate directly with the central government. A First Ministers conference of the prime minister and the provincial premiers is the de facto highest political forum in the land, although it is not mentioned in the constitution.

Federations often have special procedures for amendment of the federal constitution. As well as reflecting the federal structure of the state this may guarantee that the self-governing status of the component states cannot be abolished without their consent. An amendment to the constitution of the United States must be ratified by three-quarters of either the state legislatures, or of constitutional conventions specially elected in each of the states, before it can come into effect. In referendums to amend the constitutions of Australia and Switzerland it is required that a proposal be endorsed not just by an overall majority of the electorate in the nation as a whole, but also by separate majorities in each of a majority of the states or cantons. In Australia, this latter requirement is known as a double majority.

In Canada, the provincial governments derive all their powers directly from the constitution. But the territories are subordinate to the federal government and are delegated powers by it.
