In a historic ruling, the Seoul Central District Court sentenced former South Korean President Yoon Suk Yeol to life imprisonment on Thursday, February 19, 2026.

The court found him guilty of leading an insurrection following his short-lived and controversial declaration of martial law in December 2024. This verdict makes Yoon the first elected head of state in South Korea’s democratic era to receive such a sentence for rebellion.

Key Takeaways​Presiding Judge Jee Kui-youn (also cited as Ji Gwi-yeon) delivered a stern judgment, emphasizing that the former president’s actions were a direct assault on the nation’s constitutional order.

The Insurrection Charge: The court ruled that deploying armed troops to the National Assembly to obstruct the legislative process met the legal definition of an “uprising aimed at excluding state authority.”

Life vs. Death Penalty: While prosecutors had sought the death penalty, the court opted for life imprisonment. The judge noted that while the crime was grave, the plan was “not meticulously prepared” and there was a relative absence of direct physical violence or casualties.

​Lack of Remorse: A significant factor in the heavy sentence was Yoon’s perceived lack of remorse. The court noted he had not offered an apology to the public and had frequently refused to attend hearings during the trial.

Sentences for Co-Defendants​Yoon was not the only high-ranking official sentenced. Several key figures involved in the martial law decree also received significant prison terms:

Kim Yong-hyun (Former Defense Minister): 30 years for his central role in planning and mobilizing the military

Noh Sang-won (Former Intelligence Chief): 18 years.

Cho Ji-ho (Former National Police Agency Commissioner): 12 years.

The political atmosphere in Seoul remains incredibly tense. Thousands of both pro-Yoon and anti-Yoon protesters gathered outside the court, highlighting the deep polarization within the country

Appeals: Yoon’s legal team has already expressed strong disagreement with the ruling, calling it “a collapse of the rule of law,” and is expected to appeal the verdict to a higher court.

Additional Trials: This is just one of several legal battles for the former leader. He is already serving a five-year sentence for separate charges of resisting arrest and fabricating documents, with six more trials still pending.
