A South Korean court ruled on Wednesday that the 2024 imposition of martial law by then-President Yoon Suk Yeol constituted an act of rebellion as it sentenced his prime minister to 23 years in prison for his involvement.

Ex-Prime Minister Han Duck-soo became the first Yoon administration official convicted of rebellion charges in relation to Yoon’s martial law imposition in December 2024. The verdict is expected to set the stage for upcoming rulings involving Yoon and his other associates, who also face rebellion charges.
