Former South Korean President Yoon Suk Yeol Sentenced to 30 Years

South Korea’s former President Yoon Suk Yeol received a 30-year prison sentence as the Seoul Central District Court found him guilty of ordering drone flights over Pyongyang in 2024. These actions aimed to escalate tensions with North Korea to justify declaring martial law domestically.

The court also sentenced Yoon’s former defense minister, Kim Yong Hyun, for aiding an adversary and abusing their power. They attempted to provoke North Korea into launching attacks or other severe provocations, creating a perceived national emergency. This conduct reportedly damaged South Korea’s military interests by exposing its capabilities and prompting North Korea to strengthen its defenses.

Previously, Yoon faced a life sentence for rebellion related to his imposition of martial law in December 2024. The court’s recent ruling stems from accusations by North Korea, alleging Seoul flew drones over Pyongyang multiple times in October 2024, distributing propaganda leaflets. Despite vague denials from South Korea’s Defense Ministry, tensions heightened, though no military clashes occurred.

Yoon’s legal defense criticized the ruling. They argued that the drone flights came as a response to North Korean provocations earlier in 2024. They expressed concerns that a guilty verdict could weaken South Korea’s security but have not announced plans for an appeal.

Special prosecutor Cho Eun-suk led investigators seeking a 30-year term for Yoon. They accused him of instigating warlike scenarios as part of an authoritarian plot to eradicate political rivals and concentrate power. Investigators also pursued a 25-year term for Kim Yong Hyun, a close associate of Yoon, who aided in planning and executing the martial law declaration.

Yoon implemented martial law late on December 3, 2024, delivering a televised speech accusing liberal lawmakers of being North Korean sympathizers. His grievances included their impeachment efforts against officials and cuts to his budget. This martial law lasted only about six hours before lawmakers repealed it, breaking through military and police blockades at the National Assembly. Yoon’s cabinet was thus forced to retract the measure.

Following these events, Yoon was suspended, impeached, and removed from office by the Constitutional Court. He was arrested in July 2025, and numerous criminal trials continue. The most serious case, involving rebellion, remains under appeal by both Yoon and prosecutors who initially sought a death sentence.
