FORMER South Korean President Yoon Suk Yeol was sentenced to life in prison for his brief imposition of martial law in a dramatic culmination to the country’s biggest political crisis in decades. Yoon was ousted from office after a baffling attempt to overcome an opposition-controlled legislature by declaring martial law and sending troops to surround the National Assembly on December 3, 2024. Judge Jee Kui-youn of the Seoul Central District Court said he found Yoon guilty of rebellion for mobilizing military and police forces in an illegal attempt to seize the liberal-led Assembly, arrest politicians and establish unchecked power for a “considerable” time.

 

Martial law crisis recalled dictatorial past Yoon’s martial law imposition, the first of its kind in more than four decades, harkened back to South Korea’s past military-backed Governments when authorities occasionally proclaimed emergency decrees that allowed them to station soldiers, tanks and armoured vehicles on streets or at public places such as schools to prevent anti-government demonstrations.

 

As lawmakers rushed to the National Assembly, Yoon’s martial law command issued a proclamation declaring sweeping powers, including suspending political activities, controlling the media and publications, and allowing arrests without warrants. The decree lasted about six hours before being lifted after a quorum of lawmakers managed to break through a military blockade and unanimously voted to lift the measure. Yoon was suspended from office on December 14, 2024, after being impeached by lawmakers and was formally removed by the Constitutional Court in April 2025. He has been under arrest since last July while facing multiple criminal trials, with the rebellion charge carrying the most severe punishment. Yoon’s lawyers reject conviction .
