Former South Korean President Yoon Suk-yeol appeals his life sentence for leading a 6-hour 2024 martial law coup attempt.

Yoon Suk-yeol, the former president of South Korea, has appealed his life sentence for rebellion after being found guilty of imposing martial law in December 2024, which lasted for six hours before lawmakers overturned it. The Seoul Central District Court declared that his use of police and military force to target political leaders and block the National Assembly was an insurgency and a violation of the constitution. Yoon, who was removed from office in April 2025 after being impeached in December 2024, argues that his actions were required to combat legislative obstruction. His appeal, which was submitted on February 24, 2026, accuses the court of political bias and contests its legal reasoning. At the Seoul High Court, a specialized panel is currently reviewing the case.
