A South Korean court has sentenced former president Yoon Suk Yeol to life imprisonment after finding him guilty of masterminding an insurrection linked to his failed attempt to impose military rule in December 2024.
The court ruled that Yoon’s declaration of martial law — which lasted only six hours before lawmakers intervened — destabilised the government, polarised the country, and triggered a constitutional crisis.
He had earlier been impeached, arrested, and charged with multiple offences stemming from the episode.
Supporters gathered outside the courthouse in Seoul following the verdict, with some calling for an appeal while others expressed shock and disappointment.
Analysts say the ruling is unlikely to end the legal and political saga surrounding the former leader, who still faces additional trials related to the martial law order.
Correspondents report that Yoon is expected to challenge the decision in higher courts, a process that could take months.
He also retains the option of seeking a presidential pardon, though that appears unlikely under the current administration led by Lee Jae Myung.
The case has deepened political divisions within South Korea, where the brief imposition of martial law continues to shape national debate about democracy, security, and executive power.
Other officials linked to the incident have also been convicted, including former cabinet members and security chiefs accused of supporting the failed attempt.
Observers say the verdict underscores the judiciary’s determination to hold public officials accountable for actions seen as threatening constitutional order.
