Overview

The National Assembly is the single‑chamber national legislature of the Republic of Korea. It comprises 300 members who serve four‑year terms and performs the principal lawmaking and oversight functions in South Korea's democratic system. The institution sits in Seoul and acts as the principal forum for debate, enactment of statutes, budget approval and scrutiny of the executive branch.

Composition and organization

The Assembly's membership is drawn from two complementary election methods. A majority of seats are filled by representatives elected from single‑member constituencies across the country, while a set number of seats are allocated by party list through proportional representation. As a collective body the Assembly elects a presiding speaker and organizes its work into standing committees that consider proposed legislation and conduct investigations.

Powers and functions

The National Assembly performs a mix of legislative, budgetary and oversight duties. Its core responsibilities include:

  • Drafting, debating and passing laws that govern national policy.
  • Reviewing, amending and approving the national budget and public accounts.
  • Examining treaties and international agreements submitted by the executive.
  • Conducting hearings, interpellations and inquiries to hold ministers and agencies accountable.
  • Initiating or participating in constitutional procedures such as impeachment and removal of public officials under the constitutional framework.

Electoral system

Members are elected for four‑year terms. The legislature combines constituency representation with party list proportional seats to balance local accountability and broader party proportionality. The exact allocation rules and any recent reforms determine how proportional seats are distributed among parties. Regular legislative elections are held on a fixed cycle, and changes in party strength within the Assembly influence government policy and oversight intensity.

History and development

The National Assembly traces its origins to the founding of the modern Korean state in the mid‑20th century and has evolved through periods of political change. Over successive constitutions and political transitions it has shifted from constrained roles during authoritarian eras to a stronger oversight and representative body in the democratic era. Its procedures, committee system and electoral arrangements have been adjusted over time to respond to changes in political practice and electoral law.

Practical importance and notable facts

As the chief representative organ, the Assembly shapes domestic policy, approves public spending and provides a constitutional check on executive power. It is the venue where parties negotiate legislation and where citizens' representatives raise regional and national concerns. The Assembly's public sessions, committee hearings and confirmation or oversight activities are key mechanisms for transparency and political accountability. The National Assembly Building, located on the Yeouido island of Seoul, houses plenary sittings and committee rooms and is a frequent focal point for civic demonstrations and media coverage.
