In parliamentary systems, a dissolution of parliament is the dispersal of a legislature at the call of an election.
Usually there is a maximum length of a legislature, and a dissolution must happen before the maximum time. Early dissolutions are allowed in many jurisdictions.
The
House of Representatives, but not the
Senate can be dissolved at any time by the
Governor-General. The House expires 3 years after its first meeting if not earlier dissolved. The Senate can be dissolved by the governor-general only when the
double dissolution provisions are invoked. The convention is that the governor-general must act on the advice of the
Prime Minister. Although to fulfil this 'convention' in 1975 the Governor General dismissed the elected Labour Prime Minister
Gough Whitlam in order to precipitate an early General Election.
The
House of Commons, but not the
Senate, can be dissolved at any time by the
Governor General on the advice of the
Prime Minister. A House of Commons that sits for a full 5 years is automatically dissolved.
A dissolution can only happen if the
Chancellor loses a
vote of confidence, although in
1982,
Helmut Kohl deliberately lost one in order that there could be fresh elections. A similar vote happened in
2005 as a means for Chancellor
Schröder to ask for early elections.
The
House of Representatives, but not the
House of Councillors, can be dissolved at any time by the
Emperor on the advice of the
Prime Minister.
The
Parliament can be dissolved or prorogued at any time in its 3-year term by the
Governor-General, usually on the advice of the
Prime Minister.
The
Oireachtas can be dissolved by the
President if there is a
vote of no confidence in the
Taoiseach, but the president may refuse to dissolve it thus preventing an election and allowing the opposition leader to form a government.
Parliament of the United Kingdom
The
Prime Minister may ask the
monarch to dissolve
Parliament at any time, though it must be dissolved five years after the last
general election as that is the maximum term a parliament may sit by virtue of the
Septennial Act 1715, as amended by the
Parliament Act 1911, which reduced the Septennial Act's seven-year limit.
Scottish Parliament
Under the Scotland Act 1998, ordinary general elections for the Scottish Parliament are held on the first Thursday in May every four years (1999, 2003, 2007 etc.) The date of the poll may be varied by up to one month either way by the Queen on the proposal of the Presiding Officer.
If the Parliament itself resolves that it should be dissolved (with at least two-thirds of the Members voting in favour), or if the Parliament fails to nominate one of its members to be First Minister within certain time limits, the Presiding Officer proposes a date for an extraordinary general election and the Parliament is dissolved by the Queen by royal proclamation.
