South Korea Ex-President Yoon Gets Life Sentence

South Korea’s former president Yoon Suk Yeol has been sentenced to life imprisonment after a Seoul court found him guilty of masterminding an insurrection by attempting to impose martial law.

The landmark ruling marks one of the most dramatic chapters in the country’s modern political history and deepens divisions within a nation still grappling with the fallout from the crisis.

The Seoul Central District Court ruled that Yoon’s decision on 3 December 2024 to deploy troops around the National Assembly and order the arrest of political opponents amounted to a deliberate attempt to undermine the constitution.

Presiding judge Ji Gwi-yeon described him as the “insurrectionist leader”, stating that his actions inflicted profound damage on South Korea’s democracy and warranted severe punishment. Prosecutors had sought the death penalty.

Although the judging panel found insufficient evidence to conclude that the martial law order had been premeditated a year in advance, it determined that the events constituted a coordinated effort to subvert constitutional governance.

Yoon remained expressionless as the verdict was read. His legal team immediately criticised the ruling, claiming it lacked evidential backing and accusing the court of delivering a predetermined outcome. Any appeal would move the case to the Supreme Court, potentially prolonging legal proceedings for months.

Yoon stunned the country when he declared martial law during a live television broadcast, claiming the measure was necessary to counter so-called “anti-state” forces aligned with North Korea.

However, critics argue that the move was driven by mounting domestic pressure. The opposition-controlled parliament had significantly curtailed his authority, while corruption allegations surrounding his wife, Kim Keon Hee, further weakened his administration.

Lawmakers forced their way into the National Assembly within hours to overturn the decree, compelling Yoon to rescind the order. What followed was political turmoil, impeachment proceedings, and multiple indictments targeting senior officials.

The insurrection case has ensnared several high-ranking figures. Former prime minister Han Duck-soo received a 23-year prison term, while ex-defence minister Kim Yong-hyun was sentenced to 30 years for advising the imposition of martial law.

Other officials, including former interior minister Lee Sang-min, intelligence commander Roh Sang-won and police chief Cho Ji-ho, have also been jailed. Judges characterised the episode as “an insurrection from the top”, underscoring the scale of institutional involvement.

Yoon is already serving time for abuse of power and obstructing his own arrest. He faces three additional related trials.

Security was tight around the courthouse as thousands gathered ahead of the sentencing. Supporters waved banners reading “Yoon, again”, some visibly distressed by the verdict. Anti-Yoon demonstrators demanded capital punishment.

The ruling Democratic Party, which returned to power following Yoon’s impeachment, criticised the court for not imposing the death penalty. Party leader Jung Chung-rae described the life sentence as inadequate given the severity of the offence.

South Korea has not carried out an execution since 1997, meaning a death sentence would likely have resulted in life imprisonment in practice.

South Korea has a history of former presidents being convicted and later pardoned. Several previous leaders served between two and five years before receiving clemency.

Many political observers believe Yoon could eventually receive similar treatment, though the depth of public division may complicate that prospect.

For now, the life sentence stands as a stark warning about the fragility of democratic institutions and a defining moment in South Korea’s ongoing struggle over constitutional authority and executive power.
