On January 16, 2026, the Seoul Central District Court sentenced former South Korean President Yoon Suk Yeol to five years in prison for obstructing authorities from arresting him after his failed attempt to impose martial law in December 2024. The court found him guilty of mobilising the presidential security service to block investigators, fabricating official documents, and bypassing the legal requirement that martial law must be discussed in a formal cabinet meeting. The ruling, delivered in televised proceedings, marked the first conviction tied to his botched martial law declaration. Judges noted that Yoon had abused his presidential influence to prevent the execution of legitimate warrants, effectively turning state officials into instruments of personal protection. Yoon, 65, appeared slimmer and listened silently as the verdict was read in a packed courtroom filled with supporters, showing no reaction when the sentence was announced. His lawyer, Yoo Jung-hwa, immediately vowed to appeal, calling the decision politicised, while prosecutors declined to comment on whether they would also appeal. In a separate trial, prosecutors have sought the death penalty, accusing Yoon of masterminding an insurrection by attempting to impose military rule and suspend parliament.
Yoon’s downfall began in January 2025 when he barricaded himself inside his residence and ordered security forces to block investigators, leading to a dramatic arrest involving more than 3,000 police officers—the first time a sitting South Korean president had ever been arrested. Parliament swiftly overturned his martial law decree, impeached him, and suspended his powers, and in April 2025 the Constitutional Court formally removed him from office for violating his presidential duties. Though his martial law bid lasted only six hours, it sent shockwaves through South Korea, a key U.S. ally and one of Asia’s largest democracies. Outside the court, dozens of supporters gathered under tight police security, holding placards claiming Yoon was the victim of a political witch hunt and insisting “history will be the judge.” His case adds to South Korea’s long history of presidents facing criminal convictions, echoing the fate of former general Chun Doo-hwan, who was sentenced to death in 1996 for the brutal Gwangju crackdown but later pardoned
