Many
parliaments or other
legislatures consist of two 'chambers': an
elected lower house, and an
upper house or
Senate which may be appointed or elected by a different mechanism from the lower house. This style of two houses is called
bicameral. Legislatures with only one house are known as
unicameral.
The lower house is almost always the originator of
legislation, and the upper house is the body that offers the "second look" and decides whether to
veto or approve the
bills. In the
United Kingdom legislation can be originated in either house, but the lower house can ultimately prevail if the two houses repeatedly disagree. In most countries the lower house, regarded as more particularly the representatives of the people, has sole or predominant control over matters to do with
finance and
taxation.
A parliament's lower house is usually composed of at least 100
members, in countries with populations of over 3 million. The number of seats rarely exceeds 400, even in very large countries. In the United Kingdom however, the lower house (the
House of Commons) has 650 members. The upper house customarily has anywhere from 20, 50, or 100 seats, but almost always significantly less than the lower house. In the United Kingdom however, the upper house (the
House of Lords) currently has slightly more members than the lower house, and at one time (before the exclusion of most of the
hereditary peers) had considerably more.
Merging of chambers
Until
1971, the
Riksdag in
Sweden was similarly divided into the ''Första kammaren'' and ''Andra kammaren'', but has since been a
unicameral legislature. The
Norwegian parliament (''Storting'') is officially divided in two chambers, but functions as a single chamber in practice, a situation called
Qualified unicameralism.
Floor and Committee
The ''
Floor'' is the name for the full Assembly, and a ''
Committee'' is a small deliberative Assembly that is usually subordinate to the floor.
