A South Korean appeals court increased former president Yoon Suk Yeol's prison sentence to seven years on the event date 2026-04-29, according to the supplied evidence, deepening the legal fallout from the political crisis that followed his failed 2024 martial law declaration. The Seoul High Court raised the sentence from five years after reviewing convictions connected to obstruction of justice and abuse of power.
The case centered in part on Yoon's use of presidential security personnel to block his own arrest. The source says a lower court had already found that he used security agents to interfere with the lawful execution of warrants. On appeal, Yoon argued that the warrants were the product of an unlawful investigation, while prosecutors said a 10-year sentence was more appropriate because of the seriousness of the offenses.
The appeals court settled on seven years. In the evidence packet, the judge described Yoon's actions as highly reprehensible and said he not only obstructed lawful warrants but also gave unlawful instructions to members of the presidential security service, treating national civil servants as if they were personal guards. Yoon appeared in court wearing a black suit and white shirt and showed little visible emotion as the verdict was delivered.
The court also upheld his conviction for abuse of power tied to excluding cabinet members from a meeting to plan the imposition of martial law. It overturned a lower-court acquittal on a separate abuse-of-power count involving an order to distribute his defense of martial law to foreign media. At the same time, the appeals court agreed with the lower court that Yoon had prepared falsified documents, though it maintained the finding that he had not actually used them.
His lawyers said he would appeal to the Supreme Court. But even that next appeal unfolds against a much more serious legal backdrop. According to the source, Yoon is already serving a life sentence for leading an insurrection linked to the same broader crisis. In December 2024, he declared martial law in a late-night televised address, invoking North Korean influence and anti-state forces as justification for suspending civilian rule. The move lasted only about six hours before lawmakers reached the assembly and voted it down.
That declaration triggered protests, rattled financial markets and surprised allies including the United States, while also reviving memories of South Korea's earlier periods of military rule. In the aftermath, Yoon was impeached, removed from office and prosecuted across multiple fronts.
The supplied evidence also says he faces a separate trial on charges of aiding the enemy, tied to allegations that he ordered military drones into North Korea earlier in 2024 in an effort to provoke a response that would strengthen his case for martial law. Prosecutors are seeking a 30-year sentence in that matter, while his legal team denies he gave such an order. His wife, former first lady Kim Keon Hee, is also in prison on unrelated corruption charges.
The event dated 2026-04-29 therefore marks not just a sentence increase but another step in the dismantling of a presidency that collapsed into one of the most severe constitutional and criminal reckonings in recent South Korean politics.
