South Korea’s impeached former president Yoon Suk Yeol has been sentenced to five years in prison after being found guilty of abusing power, obstructing justice and falsifying documents linked to his attempted martial law in 2024. Friday’s ruling is the first verdict in a series of four trials related to his controversial decree, which triggered nationwide protests and political unrest. The judge noted that Yoon ‘plunged the country into a political crisis’ and showed ‘no remorse’ for his actions.

Conviction details and charges

Yoon was convicted of using presidential bodyguards to prevent his arrest, failing to consult his full cabinet before declaring martial law and creating then destroying a falsified document claiming support from the prime minister and defence minister. Prosecutors had requested a 10-year sentence, while Yoon argued the arrest and investigation were legally invalid and that consulting all cabinet members was not required. Both sides now have seven days to appeal.

This ruling offers insight into Yoon’s remaining trials, which include charges ranging from abuse of power to campaign law violations. The most serious allegation, insurrection, carries a potential death sentence, with the verdict expected in February.

Public reaction and political impact

Around 100 Yoon supporters gathered outside the courthouse to watch the proceedings on a large screen. Some held banners reading ‘Yoon, again! Make Korea great again,’ while others voiced outrage at the verdict. The trials underscore South Korea’s deep political divisions, as Yoon still has a loyal following despite his failed martial law attempt. A recent survey showed nearly 30% of citizens did not consider his actions an insurrection.

Six months after the martial law attempt, voters elected opposition leader Lee Jae Myung in a decisive win. Analysts say the outcome of Yoon’s ongoing trials will further shape the nation’s political landscape and set precedents for holding leaders accountable for constitutional violations.
