Former President Yun Seok-yeol Sentenced to 30 Years in Prison

A district court in Seoul, South Korea, found former President Yun Seok-yeol guilty and sentenced him to 30 years in prison on charges of power abuse related to a drone flight into North Korea in 2024.

If he does not succeed in his appeal, this sentence will be added to a life sentence he received back in February. This earlier sentence stemmed from a failed attempt to impose martial law in December 2024, which he defended as necessary for restricting citizens’ rights due to perceived threats. This martial law was short-lived; lawmakers rapidly voted to repeal the order after briefly encountering soldiers enforcing it. Yun was arrested shortly thereafter, leading to his impeachment and a chaotic period for South Korea, which saw five different presidents in just six months.

The situation stabilized with elections in mid-2025, bringing current President Lee Jae-myung, who had been Yun’s rival in the 2022 presidential race, into power. President Lee, a former leader of the Democratic Party, has indicated his intent to hold those responsible for the martial law accountable and has shifted the country’s foreign policy to foster better relations with North Korea and China, despite the ongoing technical state of war between South Korea and the North.

According to reports, the Seoul Central District Court concluded that Yun’s actions in flying the drone into North Korean airspace in October 2024 exacerbated tensions between the two nations. The court found him guilty of both abuse of power and “gaining the enemy.” While active conflict was paused with a 1953 armistice, making it more of a tense standoff, the court argued that Yun deliberately worsened relations with North Korea to create the rationale for declaring martial law, which he did approximately two months after the drone incident.

The ruling asserted, “The defendants provoked North Korea’s provocation under the guise of a military operation in order to create an environment for emergency martial law.”

Following the drone flight, North Korea announced military preparations aimed at South Korea, citing the act as an aggression. Their Ministry of Foreign Affairs accused South Korea of committing severe offenses, including anti-North demonstrations, during that period.

Unlike his predecessor, Moon Jae-in, who attempted to build a rapport with North Korea’s Kim Jong-un, Yun adopted a much tougher approach. He even briefly considered a nuclear weapons program for South Korea to counter the North’s threats, though this was later reconsidered after discussions with then-President Joe Biden regarding the provision of a nuclear submarine to South Korea.

The chain of events that led to Yun’s downfall began on December 3, 2024, when he announced on television plans to declare military rule, claiming it was essential for protecting the Republic of Korea from the North Korean army. He expressed frustration at the Democratic Party’s majority in the National Assembly, arguing their resistance to conservative initiatives constituted a national security risk.

However, this declaration faced strong opposition from most of the public, including members of his own party. Soon after, lawmakers stormed the National Assembly in a dramatic bid to vote down martial law, encountering little resistance from the military.

Martial law was overturned that night, sparking significant online discussions. Following this, Yun was quickly impeached, succeeded by various interim leaders until Lee took office in 2025.

Yun ultimately faced various charges related to the martial law crisis, the most notable being insurrection. The court’s ruling on the drone incident this week added to a conviction for sedition he received a few months earlier, resulting in a life sentence, with prosecutors even seeking the death penalty at one point.

Judge Ji Kwi-young, in the court’s explanation, emphasized that Yun’s actions aimed to undermine the Constitution, such as by deploying the military to the National Assembly and disrupting its functions. He noted that while martial law restricts the powers of other government branches, simply declaring it doesn’t inherently equate to an insurrection. The judge concluded that Yun’s actions had the potential to disturb peace not just across the country but particularly in the Seoul metropolitan area, where the National Assembly is located.
