South Korea's former President Yoon Suk-yeol has been found guilty of masterminding an insurrection and sentenced to life in prison over his imposition of short-lived martial law in 2024. "The declaration of martial law resulted in enormous social costs, and it is difficult to find any indication that the defendant has expressed remorse for that," Presiding Judge Ji Gwi-yeon told the court on Thursday. "As to defendant Yoon Suk-yeol, the crime of insurrection leadership is established," the judge said. "We sentence Yoon to life imprisonment." The Seoul Central District Court ruled that Yoon was the leader of the December 3, 2024 insurrection in a case where prosecutors had sought the death penalty for the disgraced ex-president, who was impeached and removed from office over his declaration of martial law.
