National Assembly (South Korea)

The National Assembly of the Republic of Korea (Korean: 대한민국 국회) is the unicameral national legislature of South Korea. Elections to the National Assembly are held every four years. The latest legislative elections were held on 10 April 2024. The current National Assembly held its first meeting, and also began its current four year term, on 30 May 2024. The current Speaker was elected 5 June 2024. The National Assembly has 300 seats, with 253 constituency seats and 47 proportional representation seats; 30 of the PR seats are assigned an additional member system, while 17 PR seats use the parallel voting method.
The unicameral assembly consists of at least 200 members according to the South Korean constitution. In 1990 the assembly had 299 seats, 224 of which were directly elected from single-member districts in the general elections of April 1988. Under applicable laws, the remaining seventy-five representatives were elected from party lists. By law, candidates for election to the assembly must be at least thirty years of age. As part of a political compromise in 1987, an earlier requirement that candidates have at least five years' continuous residency in the country was dropped to allow Kim Dae-jung, who had spent several years in exile in Japan and the United States during the 1980s, to return to political life. The National Assembly's term is four years. In a change from the more authoritarian Fourth Republic and Fifth Republic (1972–81 and 1981–87, respectively), under the Sixth Republic, the assembly cannot be dissolved by the president.
The main building in Yeouido, Seoul, is a stone structure with seven stories above ground and one story below ground. The building has 24 columns, which means the legislature's promise to listen to people 24/7 throughout the year.
The constitution stipulates that the assembly is presided over by a Speaker and two Deputy Speakers, who are responsible for expediting the legislative process. The Speaker and Deputy Speakers are elected in a secret ballot by the members of the Assembly, and their term in office is restricted to two years. The Speaker is independent of party affiliation (to compared to the two vice-speakers who are affiliated with the two leading political parties), and the Speaker and Deputy Speakers may not simultaneously be government ministers.
The Secretary General of the National Assembly is the head of the Secretariat of the National Assembly, which is the department that oversees the affairs of the National Assembly. They are government officials and are treated as ministers. (Ministerial level). As with the President of the National Assembly, party membership is limited and he must be affiliated to no political party during his term in the Assembly.
Parties that hold at least 20 seats in the assembly form floor negotiation groups (Korean: 교섭단체, Hanja: 交涉團體, RR: gyoseop danche), which are entitled to a variety of rights that are denied to smaller parties. These include a greater amount of state funding and participation in the leaders' summits that determine the assembly's legislative agenda.
In order to meet the quorum, the United Liberal Democrats, who then held 17 seats, arranged to "rent" three legislators from the Millennium Democratic Party. The legislators returned to the MDP after the collapse of the ULD-MDP coalition in September 2001.
For a legislator to introduce a bill, they must submit the proposal to the Speaker, accompanied by the signatures of at least ten other assembly members. A committee must then review the bill to verify that it employs precise and orderly language. Following this, the Assembly may either approve or reject the bill.
There are 17 standing committees which examine bills and petitions falling under their respective jurisdictions, and perform other duties as prescribed by relevant laws.
The National Assembly has 300 seats, with 254 constituency seats under FPTP and 46 proportional representation seats. With electoral reform taken in 2019, the PR seats apportionment method was replaced by a variation of additional member system from the previous parallel voting system. However, 17 seats were temporarily assigned under parallel voting in the 2020 South Korean legislative election.
Per Article 189 of Public Official Election Act, the PR seats are awarded to parties that have either obtained at least 3% of the total valid votes in the legislative election or at least five constituency seats. The number of seats allocated to each eligible party is decided by the formula:
n initial = ⌊ ( n Assembly − n ineligibles ) × PR votes ratio − n obtained constituencies + 1 2 ⌋ {\displaystyle n_{\text{initial}}=\left\lfloor {\frac {(n_{\text{Assembly}}-n_{\text{ineligibles}})\times {\text{PR votes ratio}}-n_{\text{obtained constituencies}}+1}{2}}\right\rfloor }
where
If the integer is less than 1, then ninitial is set to 0 and the party does not get any seats. Then the sum of initially allocated seats is compared to the total seats for the additional member system and recalculated.
n remainder = ( n ams − ∑ n initial ) × PR votes ratio {\displaystyle n_{\text{remainder}}=\left(n_{\text{ams}}-\sum n_{\text{initial}}\right)\times {\text{PR votes ratio}}}
n final = { n initial + n remainder , if ∑ n initial < n ams n ams × n initial ∑ n initial , if ∑ n initial > n ams {\displaystyle n_{\text{final}}={\begin{cases}n_{\text{initial}}+n_{\text{remainder}},&{\text{if }}\sum n_{\text{initial}}<n_{\text{ams}}\\n_{\text{ams}}\times {\dfrac {n_{\text{initial}}}{\sum n_{\text{initial}}}},&{\text{if }}\sum n_{\text{initial}}>n_{\text{ams}}\end{cases}}}
Final seats are assigned through the largest remainder method, and if the remainder is equal, the winner is determined by lottery among the relevant political parties.
The voting age was also lowered from 19 to 18 years old, expanding the electorate by over half a million voters.
From 2004 to 2009, the assembly gained notoriety as a frequent site for legislative violence. The Assembly first came to the world's attention during a violent dispute on impeachment proceedings for then President Roh Moo-hyun, when open physical combat took place in the assembly. Since then, it has been interrupted by periodic conflagrations, piquing the world's curiosity once again in 2009 when members battled each other with sledgehammers and fire extinguishers. The National Assembly since then has taken preventive measures to prevent any more legislative violence.
Elections for the assembly were held under UN supervision on 10 May 1948. The First Republic of Korea was established on 17 July 1948 when the constitution of the First Republic was established by the Assembly. The Assembly also had the job of electing the president and elected anti-communist Syngman Rhee as president on 10 May 1948.
Under the first constitution, the National Assembly was unicameral. Under the second and third constitutions, the National Assembly was to be bicameral and consist of the House of Representatives and the House of Councillors, but in practice, the legislature was unicameral because the House of Representatives was prevented from passing the law necessary to establish the House of Councillors.
