Government of South Korea

The Government of South Korea is divided into executive, judicial, and legislative branches. The executive and judicial branches operate primarily at the national level, although various ministries in the executive branch also carry out local functions. Local governments are semi-autonomous, and contain executive and legislative bodies of their own. The judicial branch operates at both the national and local levels. The South Korean government's structure is determined by the Constitution of the Republic of Korea. This document has been revised several times since its first promulgation in 1948 (for details, see History of South Korea). However, it has retained many broad characteristics; with the exception of the short-lived Second Republic of South Korea, the country has always had a presidential system with a relatively independent chief executive. The current structure is a semi-presidential system.

As with most stable three-branch systems, a careful system of checks and balances is in place. For instance, the judges of the Constitutional Court are partially appointed by the executive, and partially by the legislature. Likewise, when a resolution of impeachment is passed by the legislature, it is sent to the judiciary for a final decision.
