It said the moves harmed South Korea's military interests by exposing its capabilities, undermining its ability to conduct future operations and prompting North Korea to strengthen its defence posture.The same court earlier sentenced Yoon to life in prison for a rebellion conviction over his short-lived imposition of martial law in December 2024.North Korea accused Seoul of flying drones over Pyongyang to drop propaganda leaflets three times in October 2024. Kim, who was South Korea's defence minister at the time, issued a vague denial before the Defence Ministry said it could neither confirm nor deny the allegations. Tensions rose sharply but did not lead to any military clashes.WATCH | Yoon was sentenced earlier this year on separate charges:South Korea’s former president sentenced to life in prison | About ThatFebruary 20|Duration 1:31Andrew Chang explains why Yoon Suk Yeol, former president of South Korea, was sentenced to life in prison after being found guilty of leading an insurrection with his 2024 declaration of martial law.Yoon's lawyers appealed Friday's ruling and criticized it, saying the drone flights were a response to North Korea flying thousands of trash-carrying balloons into the South earlier in 2024. They argued that a guilty verdict would undermine South Korea's security interests.Investigators led by special prosecutor Cho Eun-suk had sought a 30-year prison term for Yoon, accusing him of trying to create a warlike situation between the Koreas while plotting an authoritarian push to remove his political opponents and "monopolize" power. They had sought a 25-year prison term for Kim, a key confidant of Yoon who helped plan and mobilize forces for Yoon's martial law declaration.Yoon proceeded with the declaration late in the night of Dec. 3, 2024, delivering a televised address in which he accused liberal lawmakers of being North Korea-sympathizing "anti-state" forces. He cited a range of grievances, but particularly the opposition's impeachments of senior officials and cuts to his government's budget bill.Kim Yong Hyun is shown speaking during a news conference in Ottawa on Nov. 1, 2024, just weeks before the stunning declaration of martial law in South Korea. Kim, the former defence minister, has faced numerous court proceedings in the past 18 months. (Adrian Wyld/The Canadian Press)Martial law lasted about six hours until lawmakers broke through a blockade of soldiers and police at the National Assembly and voted to overturn it, forcing Yoon's Cabinet to lift the measure.Yoon was quickly impeached, suspended from office, and formally removed by the Constitutional Court. He was arrested in July 2025 and several criminal trials are ongoing.The verdict in the most serious case, of rebellion, has been appealed both by Yoon and prosecutors, who had sought a death sentence.
