National Assembly of South Korea

Introduction

The National Assembly of the Republic of Korea (대한민국 국회) is the unicameral national legislature established under Chapter III (Articles 40–65) of the Constitution. Comprising 300 members elected for four-year terms, the Assembly exercises legislative, budgetary, oversight, and impeachment powers. The Assembly’s institutional role has evolved significantly since democratization, asserting greater independence from executive dominance.

Historical Development

Pre-Democratization Era

Under the First through Fifth Republics (1948–1987), the National Assembly operated under varying degrees of executive domination. During the Yushin Constitution period (1972–1979), one-third of Assembly members were appointed by the President, and legislative powers were severely curtailed.

Post-1987

The 1987 Constitution restored the Assembly’s legislative autonomy. The Assembly has increasingly asserted its oversight powers, including successful presidential impeachments (2004, 2016) and active legislative investigation.

Composition and Elections

Electoral System

The 300 Assembly members are elected through:

• 253 constituency seats: First-past-the-post in single-member districts
• 47 proportional representation seats: Allocated under a mixed-member proportional system

The 2019 electoral reform introduced a more proportional system, requiring voters to cast two ballots (one for constituency candidates, one for parties).

Election Cycle

Elections are held every four years. The National Election Commission (NEC) administers elections independently.

Officers and Leadership

Speaker and Deputy Speakers

The Assembly elects a Speaker and two Deputy Speakers for two-year terms. The Speaker:

• Presides over plenary sessions
• Represents the Assembly
• Maintains order and discipline
• Exercises procedural authority (referring bills to committees, scheduling debates)

Floor Leaders

Each party elects a floor leader who manages party strategy, negotiates with other parties, and coordinates committee assignments.

Committees

The Assembly operates through:

• Standing Committees (16): Permanent committees for specific policy areas (Legislation and Judiciary, Strategy and Finance, Foreign Affairs, etc.)
• Special Committees: Ad hoc committees for specific investigations or issues
• Select Committees: Established by resolution for particular purposes

Committees review bills, conduct hearings, and oversee executive agencies. Committee chairs have significant influence over legislative scheduling and content.

Powers and Functions

Legislative Powers

• Bill introduction, deliberation, and enactment
• Treaty ratification consent
• Constitutional amendment proposal

Financial Powers

• Budget review and approval
• Revenue authorization
• Audit of state finances

Oversight Powers

• Inspection of state affairs (annual and special investigations)

Political Dynamics

The Assembly is characterized by:

• Strong party discipline: Legislative voting follows party lines
• Executive-legislative tension: Conflict between presidential agenda and Assembly opposition
• Filibustering: Extended debate is permitted; the 2017 “filibuster on the National Security Act” lasted 192 hours

Privileges and Immunities

Members of the Assembly enjoy:

• Freedom from arrest: During session, members may not be arrested without Assembly consent (except for flagrant offenses)
• Freedom of speech: Members are not liable for statements made in official Assembly proceedings (Article 45)
• No concurrent offices: Members may not hold other public positions (Article 43)

Conclusion

The National Assembly of South Korea has evolved from a subordinate institution under authoritarian rule to a powerful, assertive legislature that effectively checks executive power. Its legislative, budgetary, and oversight functions are essential to Korean democratic governance.
