Democracy Prevails: South Korea Upholds Yoon Impeachment

South Korea's Constitutional Court unanimously upheld the impeachment of President Yoon Suk Yeol on April 4, 2025, ending a political crisis that began with his extraordinary declaration of martial law in December 2024. All six sitting justices voted to remove him from office, finding that his invocation of emergency powers had violated the constitution and represented an unacceptable threat to democratic governance. Yoon became only the second South Korean president removed through impeachment, after Park Geun-hye in 2017. Yoon had declared martial law on the evening of December 3, 2024, citing vague national security threats and accusing opposition lawmakers of sympathizing with North Korea. Military units deployed to the streets of Seoul, and soldiers briefly entered the National Assembly building. The martial law declaration stunned the nation and drew immediate comparisons to the military dictatorships that had governed South Korea until the late 1980s. The National Assembly voted to lift martial law within hours, and Yoon rescinded the order, but the damage to his presidency was irreversible. The impeachment motion passed the National Assembly on December 14 with broad bipartisan support. Prime Minister Han Duck-soo assumed the duties of acting president while the Constitutional Court deliberated. Yoon's legal team argued that the martial law declaration, while perhaps ill-advised, fell within the president's constitutional authority and did not warrant removal. Prosecutors countered that Yoon had attempted to suspend democratic governance and prevent the legislature from exercising its constitutional role. The unanimous ruling rejected every defense Yoon's team offered. The court found that the martial law declaration had no legitimate basis, that deploying troops to the National Assembly constituted an attack on legislative independence, and that Yoon's actions demonstrated he could not be trusted with presidential authority. Street demonstrations celebrating the verdict drew hundreds of thousands of people in Seoul. The crisis reinforced the resilience of South Korea's democratic institutions, which had now successfully removed two presidents through constitutional means within a single decade.
