Prorogation in the context of "Prorogatio"

In ancient Rome, a promagistrate (Latin: pro magistratu) was a person who was granted the power via prorogation to act in place of an ordinary magistrate in the field. This was normally pro consule or pro praetore, that is, in place of a consul or praetor, respectively. This was an expedient development, starting in 327 BC and becoming regular by 241 BC, that was meant to allow consuls and praetors to continue their activities in the field without disruption.

By allowing veteran commanders to stay in the field rather than being rotated out for someone who may not have had much experience in the theatre, the practice helped increase the chances of victory. Whether a commander, however, would be kept was largely decided politically and often motivated by commanders' ambitions. However, the effect of prorogation was to allow commanders to retain their positions as long as political support existed, weakening the republican check of the annual magistracy (and the rotation that implied) over commanders' activities.

The Parliament of Pakistan is the supreme legislative body of the Islamic Republic of Pakistan. It is a bicameral federal legislature, composed of the Senate and the National Assembly, with the President of Pakistan as the head of the legislature. The president, upon the advice of the Prime Minister, has full powers to summon and prorogue either house or a joint session of Parliament or to dissolve the National Assembly.

The parliament's both houses convene at the Parliament House within the governmental Red Zone of Islamabad, the federal capital. Both houses of the parliament have their own separate chambers; and in case of a joint session, the National Assembly chamber is used.

The dissolution of a legislative assembly (or parliament) is the simultaneous termination of service 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 would be followed by 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.

A legislative session is the period of time in which a legislature, in both parliamentary and presidential systems, is convened for purpose of lawmaking, usually being one of two or more smaller divisions of the entire time between two elections. A session may last for the full term of the legislature or the term may consist of a number of sessions. These may be of fixed duration, such as a year, or may be determined by the party in power. In some countries, a session of the legislature is brought to an end by an official act of prorogation, in others by a motion to adjourn sine die. In either event, the close of a session generally brings an end to all unpassed bills in the legislature, which would have to be introduced anew to continue debate in the following session.
