1. The Impeachment of Roh Moo-hyun (2004)

Background

Roh Moo-hyun, elected as South Korea's president in 2003, was a reformist leader known for his progressive agenda and efforts to challenge entrenched political norms. However, his administration was fraught with political opposition from conservative lawmakers. In March 2004, Roh became the first president in South Korea's history to face an impeachment vote, following accusations of violating election laws.

Reasons for Impeachment

• Alleged Election Law Violation: Roh openly expressed support for the pro-government Uri Party ahead of the 2004 parliamentary elections, which critics claimed violated laws requiring presidential neutrality.
• Administrative Mismanagement: Conservative lawmakers accused Roh of economic mismanagement and incompetence, although these allegations were secondary to the election law controversy.

Process and Public Reaction

• On March 12, 2004, the National Assembly voted to impeach Roh with 193 votes in favor, suspending him from his duties. Prime Minister Goh Kun assumed interim leadership.
• The impeachment was met with widespread public backlash. Large-scale protests erupted in support of Roh, with many citizens condemning the impeachment as politically motivated.

Outcome

On May 14, 2004, the Constitutional Court dismissed the impeachment, ruling that while Roh violated election laws, his actions were not severe enough to justify removal from office. Roh was reinstated as president, but the incident highlighted the growing divide between progressive and conservative forces in South Korea’s political landscape.

2. The Impeachment of Park Geun-hye (2016-2017)

Background

Park Geun-hye, South Korea’s first female president, was elected in 2012 as a conservative leader. Her presidency began with high public expectations but quickly descended into controversy. By 2016, she was embroiled in a massive corruption scandal involving her confidante, Choi Soon-sil, which led to nationwide protests demanding her resignation.

Reasons for Impeachment

• Corruption and Bribery: Park was accused of colluding with Choi Soon-sil to extort nearly $70 million from major conglomerates, including Samsung, through nonprofit foundations.
• Abuse of Power: She was accused of allowing Choi undue influence over state affairs, including access to confidential government documents.
• Neglect of Duty: Park faced criticism for her failure to properly respond to the Sewol Ferry disaster in 2014, which resulted in the deaths of over 300 people, mostly students.

Process and Public Reaction

• On December 9, 2016, the National Assembly voted overwhelmingly (234 votes in favor) to impeach Park. Millions of South Koreans had participated in peaceful candlelight protests leading up to the vote, demanding her removal.
• Park’s presidential powers were suspended immediately, and Prime Minister Hwang Kyo-ahn served as acting president.

Outcome

On March 10, 2017, the Constitutional Court unanimously upheld the impeachment, making Park the first South Korean president to be permanently removed from office. She was later convicted of corruption and sentenced to 25 years in prison, though she was pardoned in 2021 by President Moon Jae-in. Park's impeachment catalyzed the election of liberal leader Moon Jae-in, signaling a shift in South Korean politics.

3. The Impeachment of Yoon Suk-yeol (2024)

Background

Yoon Suk-yeol, South Korea’s 13th president, took office in 2022 as a conservative leader. By 2024, his presidency faced widespread public and political criticism due to economic mismanagement, escalating political tensions, and controversial decisions. The situation reached a boiling point when Yoon declared martial law in December 2024, sparking accusations of authoritarianism.

Reasons for Impeachment

• Martial Law Declaration (December 3, 2024): Yoon declared martial law, claiming it was necessary to protect the nation from "anti-state forces." The move was widely criticized as an unconstitutional power grab.
• Abuse of Power: Yoon allegedly used presidential veto powers and state authority to suppress dissent and protect personal interests.
• Incitement of Rebellion: The impeachment motion included charges of inciting unrest and ordering unlawful actions tied to the martial law declaration.

First Impeachment Attempt (December 7, 2024)

• The first impeachment motion failed as the ruling People Power Party (PPP) boycotted the vote, resulting in only 195 votes in favor, falling short of the required 200 votes.

Second Impeachment Attempt (December 14, 2024)

• A second impeachment motion was introduced on December 12, 2024, with refined charges. On December 14, the National Assembly successfully passed the motion with 204 votes in favor, exceeding the two-thirds majority requirement.
• Prime Minister Han Duck-soo assumed the role of acting president while the Constitutional Court began deliberating on the impeachment.

Public Reaction

Yoon’s impeachment came after months of public outcry:

• A July 2024 public petition calling for his removal gathered over 1 million signatures, reflecting widespread dissatisfaction.
• In November, 3,000 professors and researchers signed a letter urging his resignation, and 1,466 Catholic priests issued a statement accusing Yoon of abusing his office.

Outcome (Ongoing)

As of December 2024, the Constitutional Court is reviewing the case. With three vacant seats on the court, a unanimous decision among the remaining six judges is required to remove Yoon from office. If the impeachment is upheld, South Korea will hold a snap presidential election within 60 days.

Significance of Impeachment in South Korean Democracy

South Korea's history of presidential impeachments highlights the strength of its democratic institutions and the role of public accountability. While each case arose from unique circumstances, all reflect the following themes:

• Public Engagement: Large-scale protests played a decisive role in both Park and Yoon’s cases, demonstrating the power of civic activism.
• Rule of Law: The Constitutional Court's impartial role ensures that impeachment decisions are based on legal merit rather than political motivations.
