South Korea Appeals Court Extends Ex-President Yoon's Sentence to Seven Years

The South Korean appeals court handed down a seven-year sentence to former President Yoon Suk Yeol on April 29, 2026, an increase from the five years imposed by a lower court in January. The appellate judges found Yoon guilty of more charges related to his 2025 martial law declaration, notably mobilizing the presidential security service to prevent his arrest.

This judicial decision follows the failed martial law declaration in late 2025. The appeals court's conviction on additional charges, including the use of military and security forces to suppress opposition and interfere with the judicial process, signifies a firm stance against alleged anti-constitutional activities. The ruling is seen as a testament to South Korea's democratic institutions and reinforces that executive power remains subject to constitutional law, even when invoked under national security pretexts. It may prompt further reforms concerning presidential emergency powers.

• Defendant: Former President Yoon Suk Yeol
• New Sentence: Seven years imprisonment
• Core Charges: Martial law declaration, abuse of power, obstructing justice
• Legal Precedent: Accountability for high executive office during constitutional violations
