South Korea Court to Rule on Yoon Insurrection Case on Jan 16

By Global Leaders Insights Team | Dec 16, 2025

A South Korean court will deliver its ruling on January 16 in the insurrection case involving former President Yoon Suk Yeol, local broadcaster YTN reported on Tuesday, as the country continues to confront the legal fallout from last year’s political crisis.

Yoon faces insurrection charges stemming from his short-lived declaration of martial law in December 2024, a move that triggered immediate political backlash and constitutional scrutiny.

Prosecutors argue that the declaration constituted an unlawful attempt to deploy state power against constitutional institutions.

Yoon has denied the allegations, maintaining that his actions were taken within the scope of presidential authority.

  • South Korea court to rule on former President Yoon Suk Yeol insurrection case on Jan 16
  • Verdict on Yoon’s martial law declaration to test limits of executive power
  • Insurrection ruling seen as key moment for South Korea’s constitutional accountability

The martial law announcement was overturned within hours after the National Assembly voted to invalidate it, citing constitutional violations. The episode set off weeks of protests, parliamentary proceedings, and legal challenges, culminating in Yoon’s impeachment and removal from office earlier this year following a ruling by the Constitutional Court.

Since then, the insurrection case has proceeded through the criminal courts, drawing sustained public attention and debate. Prosecutors contend that Yoon’s decision undermined democratic governance and posed a serious threat to constitutional order. His legal team has argued that the charges are politically motivated and lack legal foundation.

The upcoming verdict is expected to be a significant moment in South Korea’s judicial system and political landscape. Under South Korean law, insurrection is among the most serious criminal charges, carrying potential penalties ranging from long-term imprisonment to life sentences. The outcome could set an important legal precedent regarding the limits of executive power.

The case has also widened investigations into other government officials and military figures linked to the martial law decision. Several former aides and senior officers are facing separate inquiries or trials related to their roles during the episode.
