Yoon Suk-yeol jailed for unconstitutional martial law, obstruction of justice, and abuse of power
Seoul – South Korea’s former President Yoon Suk-yeol has been sentenced to five years in prison for imposing martial law in December 2024, obstructing justice, and abusing presidential powers.
The ruling by the South Korean judiciary found that Yoon violated the constitution and legal procedures while trying to enforce martial law, deliberately obstructed investigative agencies, and falsified official documents to prevent his arrest. Court records also indicated that Yoon excluded certain cabinet members from key meetings to carry out his plan.
Yoon’s actions, the court stated, undermined the core responsibilities of the presidency, which include protecting the constitution and upholding the rule of law. Prosecutors argued that Yoon and former Defense Minister Kim Yong-hyun had executed a premeditated strategy to maintain control of power.
South Korean media broadcast the verdict live, sparking widespread debate. While civil society groups hailed the decision as a triumph for the rule of law, conservative circles called it politically motivated. Yoon’s legal team rejected the verdict and announced plans to appeal in a higher court, asserting that the martial law was enacted to protect national security, not for personal gain.
The 2024 martial law crisis erupted when Yoon declared emergency powers in response to perceived internal security threats. Parliament rejected the decision, initiating impeachment proceedings and mass protests, including lawyers, students, and labor groups. A crucial turning point came when a large segment of the military refused orders to fire on civilians, leading to a peaceful resolution.
On April 4, 2025, Yoon was officially removed from office following the impeachment vote. He later stated that his martial law decision was made under extreme mental stress and emphasized that he had not authorized the use of force against citizens. On January 15, 2026, Yoon was formally taken into custody, making him the first South Korean president arrested during his term.
The sentencing marks a historic moment for South Korea’s democracy, underscoring accountability at the highest level of government and reinforcing the importance of constitutional limits on presidential authority.
