|Legislatures by country|
In government, unicameralism (Latin uni-, "one" and camera, "chamber") is the practice of having a single legislative or parliamentary chamber. Thus, a unicameral parliament or unicameral legislature is a legislature which consists of a single chamber or house.
Unicameral legislatures exist when there is no widely perceived need for multicameralism. Many multicameral legislatures were created to give separate voices to different sectors of society. Multiple chambers allowed for example for a guaranteed representation of different social classes (as in the Parliament of the United Kingdom or the French States-General). Sometimes, as in New Zealand and Denmark, unicameralism comes about through the abolition of one of two bicameral chambers, or, as in Sweden, through the merger of the two chambers into a single one, while in others a second chamber has never existed from the beginning.
The principal advantage of a unicameral system is more democratic and efficient lawmaking, as the legislative process is simpler and there is no possibility of deadlock between two chambers. Proponents of unicameralism have also argued that it reduces costs, even if the number of legislators stay the same, since there are fewer institutions to maintain and support it financially. Proponents of bicameral legislatures allege that this offers the opportunity to re-debate and correct errors in either chamber in parallel, and in some cases to introduce legislation in either chamber.
The main weakness of a unicameral system can be seen as alleged lack of restraint on the majority, particularly noticeable in parliamentary systems where the leaders of the parliamentary majority also dominate the executive. There is also the risk that important sectors of society[ specify ] may not be adequately represented by the elected singular body.
Approximately half of the world's sovereign states are currently unicameral. The People's Republic of China is somewhat in between, with a legislature and a formal advisory body. China has a Chinese People's Political Consultative Conference which meets alongside the National People's Congress, in many respects an advisory "upper house".
Many subnational entities have unicameral legislatures. These include the state of Nebraska and territories of Guam and the Virgin Islands in the United States, the Chinese special administrative regions of Hong Kong and Macau, the Australian state of Queensland as well as the Northern Territory and the Australian Capital Territory, a majority of the provinces of Argentina, all of the provinces and territories in Canada, all of the German states, all of the regions of Italy, all of the Spanish autonomous communities, both the autonomous regions of Portugal, most of the states and union territories of India and all of the states of Brazil. In the United Kingdom, the devolved Scottish Parliament, the Senedd Cymru, the Northern Ireland Assembly and the London Assembly are also unicameral.
A 2018 study found that efforts to adopt unicameralism in Ohio and Missouri failed due to rural opposition.There was a fear in rural communities that unicameralism would diminish their influence in state government.
Local government legislatures of counties, cities, or other political subdivisions within states are usually unicameral and have limited lawmaking powers compared to their state and federal counterparts.
Some of the 13 colonies which became independent, such as Pennsylvania, New Jersey and New Hampshire had initially introduced strong unicameral legislature and (relatively) less powerful governors with no veto power. Pennsylvania's constitution lasted only 14 years. In 1790, conservatives gained power in the state legislature, called a new constitutional convention, and rewrote the constitution. The new constitution substantially reduced universal male suffrage, gave the governor veto power and patronage appointment authority, and added an upper house with substantial wealth qualifications to the unicameral legislature. Thomas Paine called it a constitution unworthy of America.
In 1999, Governor Jesse Ventura proposed converting the Minnesota Legislature into a single chamber.Although debated, the idea was never adopted.
Seven U.S. states, Arizona, Idaho, Maryland, New Jersey, North Dakota, South Dakota, and Washington, effectively have two-house unicamerals. In these states, districts in the upper house and the lower house are combined into a single constituency, a practice known as nesting.
The U.S. territory of Puerto Rico held a non-binding referendum in 2005. Voters approved changing its Legislative Assembly to a unicameral body by 456,267 votes in favor (83.7%) versus 88,720 against (16.3%). 2⁄3 vote the specific amendments to the Puerto Rico Constitution that are required for the change to a unicameral legislature, another referendum would have been held in the territory to approve such amendments. If those constitutional changes had been approved, Puerto Rico could have switched to a unicameral legislature as early as 2015.If both the territory's House of Representatives and Senate had approved by a
On June 9, 2009, the Maine House of Representatives voted to form a unicameral legislature, but the measure did not pass the Senate.
Because of legislative gridlock in 2009, former Congressman Rick Lazio, a prospective candidate for governor, has proposed that New York adopt unicameralism.
The United States as a whole was subject to a unicameral Congress during the years 1781–1788, when the Articles of Confederation were in effect. The Confederate States of America, pursuant to its Provisional Constitution, in effect from February 8, 1861, to February 22, 1862, was governed by a unicameral Congress.
Though the current Congress of the Philippines is bicameral, the country experienced unicameralism in 1898 and 1899 (during the First Philippine Republic), from 1935 to 1941 (the Commonwealth era) and from 1943 to 1944 (during the Japanese occupation). Under the 1973 Constitution, the legislative body was called Batasang Pambansa, which functioned also a unicameral legislature within a parliamentary system (1973-1981) and a semi-presidential system (1981-1986) form of government.
The ongoing process of amending or revising the current Constitution and form of government is popularly known as Charter Change. A shift to a unicameral parliament was included in the proposals of the constitutional commission created by former President Gloria Macapagal-Arroyo.Unlike in the United States, senators in the Senate of the Philippines are elected not per district and state but nationally; the Philippines is a unitary state. The Philippine government's decision-making process, relative to the United States, is more rigid, highly centralised, much slower and susceptible to political gridlock. As a result, the trend for unicameralism as well as other political system reforms are more contentious in the Philippines.
While Congress is bicameral, all local legislatures are unicameral: the Bangsamoro Parliament, the Sangguniang Panlalawigan (Provincial Boards), Sangguniang Panlungsod (City Councils), Sangguniang Bayan (Municipal Councils), Sangguniang Barangay (Barangay Councils) and the Sangguniang Kabataan (Youth Councils).
In modern politics and history, a parliament is a legislative body of government. Generally, a modern parliament has three functions: representing the electorate, making laws, and overseeing the government via hearings and inquiries. The term is similar to the idea of a senate, synod or congress, and is commonly used in countries that are current or former monarchies, a form of government with a monarch as the head. Some contexts restrict the use of the word parliament to parliamentary systems, although it is also used to describe the legislature in some presidential systems, even where it is not in the official name.
Congresses are formal meetings of the representatives of different countries, constituent states, organizations, trade unions, political parties or other groups. The term originated in Late Middle English to denote an encounter during battle, from the Latin congressus.
A senate is a deliberative assembly, often the upper house or chamber of a bicameral legislature. The name comes from the ancient Roman Senate, so-called as an assembly of the senior and therefore considered wiser and more experienced members of the society or ruling class.
A member of parliament (MP) is the representative of the people who live in their constituency. In many countries with bicameral parliaments, this category includes specifically members of the lower house, as upper houses often have a different title. Member of Congress or Deputy is an equivalent term in other jurisdictions. Another term is Parliamentarian.
Bicameralism is the practice of having a legislature divided into two separate assemblies, chambers, or houses, known as a bicameral legislature. Bicameralism is distinguished from unicameralism, in which all members deliberate and vote as a single group. As of 2015, about 40% of world's national legislatures are bicameral, and about 60% are unicameral.
Legislative assembly is the name given in some countries to either a legislature, or to one of its houses.
The Congress of the Philippines is the bicameral legislature of the Philippines. It consists of the Senate and the House of Representatives, although colloquially, the term "Congress" commonly refers to just the latter.
The chamber of deputies is the lower house in many bicameral legislatures and the sole house in some unicameral legislatures.
Tricameralism is the practice of having three legislative or parliamentary chambers. It is contrasted with unicameralism and bicameralism, both of which are far more common.
The speaker of a deliberative assembly, especially a legislative body, is its presiding officer, or the chair. The title was first used in 1377 in England.
An upper house is one of two chambers of a bicameral legislature, the other chamber being the lower house. The house formally designated as the upper house is usually smaller and often has more restricted power than the lower house. A legislature composed of only one house is described as unicameral.
The Parliaments of the Australian states and territories are legislative bodies within the federal framework of the Commonwealth of Australia.
A state government is the government of a country subdivision in a federal form of government, which shares political power with the federal or national government. A state government may have some level of political autonomy, or be subject to the direct control of the federal government. This relationship may be defined by a constitution.
A Member of the Legislative Assembly (MLA), is a representative elected by the voters of a state constituency to the state legislative assembly of a sub-national jurisdiction.

The legislative districts of the Philippines are the divisions of the Philippines' provinces and cities for representation in the various legislative bodies. Congressional districts are for House of Representatives, while there are districts for Sangguniang Panlalawigan, and some Sangguniang Panlungsod. For purposes of representation, the Senate, most Sangguniang Panlungsod, Sangguniang Bayan, Sangguniang Barangay and Sangguniang Kabataan are all elected at-large, although there were districts for the Senate from 1916 to 1935.
House of Representatives is the name of legislative bodies in many countries and sub-national entitles. In many countries, the House of Representatives is the lower house of a bicameral legislature, with the corresponding upper house often called a "Senate". In some countries, the House of Representatives is the sole chamber of a unicameral legislature.
