NextFin News - A South Korean appeals court on Wednesday sentenced ousted President Yoon Suk Yeol to seven years in prison, adding a fresh layer of legal retribution to the leader whose brief attempt to impose martial law in late 2024 nearly dismantled the country’s democratic foundations. The Seoul High Court found Yoon guilty of obstruction of justice and resisting arrest, ruling that he had bypassed mandatory Cabinet protocols and deployed security forces as a "private army" to evade law enforcement in the weeks following his impeachment.
The seven-year term comes on top of a life sentence Yoon received earlier this year on rebellion charges. Judge Yoon Sung-sik, presiding over the Seoul High Court, delivered a scathing verdict, stating that the former president had falsified documents to conceal the fact that he sidestepped a legally required full Cabinet meeting before his December 3, 2024, martial law declaration. The court reversed a lower court’s partial acquittal, finding that Yoon intentionally excluded nine Cabinet members from the decision-making process to simulate a formal meeting with only a select few loyalists.
Financial markets in Seoul showed a measured reaction to the sentencing, as much of the political risk had been priced in since Yoon’s formal removal from office by the Constitutional Court in April 2025. The benchmark KOSPI index edged toward the 6,700 level on Wednesday, primarily driven by robust demand for semiconductor shares rather than political developments. Meanwhile, the South Korean won traded at approximately 1,472.5 per U.S. dollar, reflecting a broader stabilization of the currency after the extreme volatility seen during the height of the constitutional crisis last year.
The sentencing marks a definitive chapter in the political rehabilitation of South Korea under the administration of Lee Jae-myung, who won the early presidential election in June 2025. While Yoon’s legal team, led by attorney Yoo Jeong-hwa, has signaled an intent to appeal to the Supreme Court, the cumulative weight of the rebellion and obstruction convictions suggests a permanent exit from public life for the conservative former prosecutor. The court’s decision to treat the deployment of security officials at the presidential residence as a criminal obstruction of justice sets a significant legal precedent for executive accountability in South Korea.
Despite the severity of the sentence, some legal observers suggest the focus may eventually shift toward the possibility of a future presidential pardon, a recurring theme in South Korean political history. However, the current public sentiment remains largely supportive of the judiciary’s firm stance. The Seoul High Court emphasized that Yoon’s actions not only paralyzed high-level diplomacy and domestic politics but also fundamentally threatened the rule of law by treating state security apparatuses as personal tools for power preservation.
