Dissolution of parliament

Dissolution of a legislative assembly (or parliament) is the mandatory simultaneous resignation of all of its members, in anticipation that a successive legislative assembly will reconvene later with possibly different members. In a democracy, the new assembly is chosen by a general election. Dissolution is distinct on the one hand from abolition of the assembly, and on the other hand from its adjournment or prorogation, or the ending of a legislative session, any of which begins a period of inactivity after which it is anticipated that the same members will reassemble. For example, the "second session of the fifth parliament" could be followed by the "third session of the fifth parliament" after a prorogation, but the "first session of the sixth parliament" after a dissolution. In most Continental European countries, dissolution does not have immediate effect – that is, a dissolution merely triggers an election, but the old assembly itself continues its existing term and its members remain in office until the new assembly convenes for the first time. In those systems, ordinarily scheduled elections are held before the assembly reaches the end of a fixed or maximum term, and do not require a dissolution. In most Westminster systems, however, a dissolution legally ends the existence of the assembly, resulting in a temporary power vacuum, which may be filled in special circumstances by recalling the old assembly if need be. Because of this peculiarity, Westminster systems also have automatically-triggered dissolutions when the assembly reaches the end of a fixed or maximum term, since the act of dissolution itself is synonymous with the end of the assembly's term, and elections cannot be held in anticipation of a dissolution. Early dissolutions may be possible in parliamentary and semi-presidential systems, to resolve conflicts between the executive and the legislature; either a "snap election" called by an executive seeking to increase its legislative support, or an election triggered by parliament withholding confidence and supply from the government.
