Prime Minister of South Korea in the context of "Impeachment of Yoon Suk Yeol"

The government of South Korea is the national government of the Republic of Korea, created by the Constitution of South Korea as the executive, legislative and judicial authority of the republic. The president acts as the head of state and is the highest figure of executive authority in the country, followed by the prime minister and government ministers in decreasing order.

The Executive and Legislative 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 relatively independent chief executive in the form of a president.

The president of the Republic of Korea (Korean: 대한민국 대통령), also known as the president of South Korea (한국 대통령), is the head of state and head of government of South Korea. The president directs the executive branch of the government and is the commander-in-chief of the Republic of Korea Armed Forces.

The Constitution of South Korea and the amended Presidential Election Act of 1987 provide for election of the president by direct, secret ballot, ending sixteen years of indirect presidential elections under the preceding two authoritarian governments. The president is directly elected to a five-year term, with no possibility of re-election. If a presidential vacancy should occur, a successor must be elected within sixty days, during which time presidential duties are to be performed by the prime minister or other senior cabinet members in the order of priority as determined by law. The president is exempt from criminal liability (except for insurrection or treason).

The Republic of Korea has no officially recognized South Korean order of precedence, yet the Office of the President (EOP) once officially declared order of precedence among the chiefs of 6 highest constitutional institutions in year 2006 as following:

1. the President of the Republic of Korea, as both head of state and leader of government
2. the Speaker of the National Assembly, as leader of legislature
3. the Chief Justice of the Supreme Court and the President of the Constitutional Court, as co-leader of the judiciary
4. the Prime Minister, as deputy leader of government
5. the Chairperson of the National Election Commission, as leader of the constitutionally independent agency for national election administration

The May 16 military coup d'état (Korean: 5·16 군사정변) or the May 16 Military Revolution (Korean: 5·16 군사혁명) was a military coup d'état in South Korea in 1961, organized and carried out by Park Chung Hee and his allies who formed the Military Revolutionary Committee, nominally led by Army Chief of Staff Chang Do-yong after the latter's acquiescence on the day of the coup. The coup rendered powerless the democratically elected government of Prime Minister Chang Myon and President Yun Posun, and ended the Second Republic, installing a reformist military Supreme Council for National Reconstruction effectively led by Park, who took over as chairman after Chang's arrest in July.

The coup was instrumental in bringing to power a new developmentalist elite and in laying the foundations for the rapid industrialization of South Korea under Park's leadership, but its legacy is controversial for the suppression of democracy and civil liberties it entailed, and the purges enacted in its wake. Termed the "May 16 Military Revolution" by Park and his allies, "a new, mature national debut of spirit", the coup's nature as a "revolution" is controversial and its evaluation contested.
