Legislative session

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. In each country the procedures for opening, ending, and in between sessions differs slightly.

Common procedure

Historically, each session of a parliament would last less than one year, ceasing with a prorogation during which legislators could return to their constituencies. In more recent times, development in transportation technology has permitted these individuals to journey with greater ease and frequency from the legislative capital to their respective electoral districts (sometimes called ridings) for short periods, meaning that parliamentary sessions typically last for more than one year, though the length of sessions varies. Legislatures plan their business within a legislative calendar, which lays out how bills will proceed before a session ceases, although related but unofficial affairs may be conducted by legislators outside a session or during a session on days in which parliament is not meeting.

While a parliament is prorogued, between two legislative sessions, the legislature is still constituted – i.e. no general election takes place and all Members of Parliament thus retain their seats. In many legislatures, prorogation causes all orders of the body – bills, motions, etc. – to be expunged.[1] Prorogations should thus not be confused with recesses, adjournments, or holiday breaks from legislation, after which bills can resume exactly where they left off. In the United Kingdom, however, the practice of terminating all bills upon prorogation has slightly altered; public bills may be carried over from one legislative session to the next.

This break takes place so as to prevent the upper house from sitting during an election campaign and to purge all upper chamber business before the start of the next legislative session. It is not uncommon for a session of parliament to be put into recess during holidays and then resumed a few weeks later exactly where it left off. Governments today end sessions whenever it is most convenient, and often, a new session will begin on the same day that the previous session ended. In most cases, when parliament reconvenes for a new legislative session, the head of state, or a representative thereof, will address the legislature in an opening ceremony.

In both parliamentary and presidential systems, sessions are referred to by the name of the body and an ordinal number – for example, the 2nd Session of the 39th Canadian Parliament or the 1st Session of the 109th United States Congress.

Procedure in Commonwealth realms

In Commonwealth realms, legislative sessions can last from a few weeks to over a year; between general elections, there are usually anywhere from one to six sessions of parliament before a dissolution by either the Crown-in-Council or the expiry of a legally mandated term limit. Each session begins with a speech from the throne, read to the members of both legislative chambers either by the reigning sovereign or a viceroy or other representative. Houses of parliament in some realms will, following this address, introduce a pro forma bill as a symbol of the right of parliament to give priority to matters other than the monarch and his or her words (always written by the cabinet of the day).[2]

United Kingdom

In the parliament of the United Kingdom, prorogation is immediately preceded by a speech to both legislative chambers, with procedures similar to the Throne Speech. The monarch usually approves the oration—which recalls the prior legislative session, noting major bills passed and other functions of the government[3]—but rarely delivers it in person, Queen Victoria being the last to do so. Instead, the speech is presented by the Lords Commissioners and read by the Leader of the House of Lords. When King Charles I dissolved the Parliament of England in 1628, after the Petition of Right, he gave a prorogation speech that effectively cancelled all future meetings of the legislature, at least until he again required finances.


Prior to 1977, it was common for the federal Parliament to consist of between one and three sessions, with Parliament being prorogued at the end of each session and recalled at the beginning of the next. This was not always the case, for instance the 10th parliament ran from January 1926 to October 1928 and was not prorogued at any time. The practice of having multiple sessions in the same Parliament gradually fell into disuse, and all Parliaments since 1978 have had a single session. Since 1990, the Parliament has been prorogued on the same day that the House is dissolved so that the Senate will not be able to sit during the election period.[4][5]


In the Canadian parliamentary systems, the legislature is typically prorogued upon the completion of the agenda set forth in the Speech from the Throne, called in the UK the legislative programme, and remain in recess until the monarch, governor general, or lieutenant governor summons parliamentarians again. In Canada, however, prorogations have triggered speculation that they were advised by the sitting prime minister for political purposes: for example, in the 40th Parliament, the first prorogation occurred in the midst of a parliamentary dispute, in which the opposition parties expressed intent to defeat the minority government, and the second was suspected by opposition Members of Parliament to be a way to avoid investigations into the Afghan detainees affair and triggered citizen protests.[6][7] Similarly, the provincial legislature for Ontario in Canada was prorogued in October 2012 under similar circumstances, and is alleged to have happened to avoid scrutiny on a number of issues.[8]

Bills are numbered within each session; for example, each period's government House Bills are numbered from C-2 to C-200 (for the House of Commons) and S-2 to S-200 (for the Senate), returning again to C-2 and S-2 following a prorogation (C-1 and S-1 always being the aforementioned pro-forma bill).

Procedure in the United States

In the United States, some state legislatures meet only part of the year. Depending upon limitations of the state's constitution, if business arises that must be addressed before the next regular session, the governor may call a special session.

In the US Congress, when the leaders of the majority party in each house have determined that no more business will be conducted by that house during that Congress, a motion is introduced to Adjourn Sine Die, literally, adjourn "without a day", effectively dissolving that house. Typically, this is done at some point after the general congressional election in November of even-numbered years. If the party in power is retained, it may happen as early as mid-November and members return to their districts for the holiday season. However, when the party in power is ousted or if important business, such as approval of appropriations bills, has not been completed Congress will often meet in a "lame-duck" session, adjourning as late as December 31, before the newly elected Congress takes office on January 3.
