Second Special Counsel Says Insurrection Ended at Yoon Impeachment Vote, Indicts Ex-President

On Wednesday, August 12, 2026, South Korea’s second comprehensive special prosecutor team clashed publicly with the separate insurrection special counsel over when former President Yoon Suk Yeol’s martial-law crisis legally ended — and used its own answer, December 14, 2024, the day the National Assembly passed his impeachment motion, to bring new charges and widen scrutiny of ruling-party lawmakers who resisted his removal.

The team led by Special Prosecutor Kwon Chang-young indicted Yoon for allegedly ordering officials to justify the December 3, 2024 emergency martial-law declaration to foreign allies. It also indicted former National Security Adviser Shin Won-sik, charged ex-public broadcaster chief Lee Eun-woo with insurrection propaganda, and sent written questionnaires to People Power Party (PPP) lawmakers about boycotting the first impeachment vote. The rival insurrection probe, led by Cho Eun-seok, rejected Kwon’s timeline the same day.

Editor’s note: This article draws on reporting from The Korea Times, Korea JoongAng Daily, Seoul Economic Daily, Yonhap, and Korean court filings, August 12–13, 2026. Legal interpretations may evolve as trials proceed.

What happened on August 12

Kwon’s office announced several moves that together reframed the insurrection’s endpoint around impeachment, not the lifting of martial law:

Action	Target	Charge / purpose
Indictment	Former President Yoon Suk Yeol	Abuse of power for ordering justification messages to allies
Indictment	Former NSA Shin Won-sik	Key role in insurrection; abuse of power (no detention)
Earlier indictment (basis for timeline)	Lee Eun-woo, ex-KTV chief	Insurrection propaganda through Dec. 14
Written questionnaires	PPP lawmakers	Why they skipped the Dec. 7 impeachment vote
Witness summons	Former PPP leader Han Dong-hoon	Dec. 4 meeting at prime minister’s residence (he refused to appear)

The comprehensive team is investigating unresolved allegations left after three earlier special counsel probes — into the insurrection, former first lady Kim Keon Hee, and the death of a Marine corporal. Its mandate runs through August 23, 2026, with final results expected August 24.

Two teams, two end dates

The legal fight centers on a single question: when did the insurrection stop?

Position	Team	End date	Rationale
Extended timeline	Kwon Chang-young (comprehensive)	Dec. 14, 2024	Impeachment passed; Yoon suspended from office
Original timeline	Cho Eun-seok (insurrection)	Dec. 4, 2024	Martial law lifted; violent coercion ceased

When indicting Lee Eun-woo on August 11, Kwon’s team said the insurrection “did not end” when the Assembly voted to lift martial law on December 4. Prosecutors argued Lee used his post at the Korea Policy Broadcasting Institute (KTV) to spread information justifying the decree through December 14, when lawmakers approved impeachment and Yoon was suspended.

On August 12, Cho’s insurrection team issued a direct rebuttal. It said its investigation and indictments had been based on the view that the crisis ended when Yoon announced martial law’s lifting. Cho cited Supreme Court precedent in military-mutiny cases, arguing that treating martial law’s withdrawal as the endpoint of insurrection acts is consistent with established legal principles.

A prosecutor who worked on Cho’s team told Korea JoongAng Daily that continuing an insurrection after December 4 is hard to square with investigations that began immediately after martial law ended — but added that if the insurrection truly continued, efforts to keep Yoon in office or block impeachment could themselves constitute participation.

Why the impeachment vote matters

Moving the endpoint from December 4 to December 14 is not a technical dispute. It expands who could face insurrection-related liability.

Under Kwon’s theory:

• Conduct between martial law’s lifting and impeachment — including messaging, meetings, and parliamentary tactics — can be treated as part of the same insurrection.
• Lawmakers who boycotted, opposed, or delayed impeachment could potentially be investigated for playing a key role in the insurrection, not merely for obstructing Yoon’s arrest.
• Officials who justified martial law to domestic or foreign audiences after December 4 may face insurrection propaganda or key-role charges rather than lesser offenses.

The team has already sent PPP lawmakers questionnaires asking why they did not participate in the first impeachment vote on December 7, 2024, and what changed before they joined the second vote on December 14, according to legal sources cited by Korean media.

Yoon indicted over messages to allies

Wednesday’s indictment marked the first time Kwon’s team charged Yoon directly. Prosecutors allege that immediately after declaring martial law on December 3, Yoon instructed the National Security Office and Foreign Ministry to send messages to the United States, Britain, Japan, and European Union partners portraying the decree as a constitutional measure to defend liberal democracy.

Messages reportedly described martial law as defending democracy and framed Yoon as opposing “pro-North Korea leftists and anti-Americanism,” according to Seoul Economic Daily.

Shin allegedly executed the order with then-deputy Kim Tae-hyo through the National Intelligence Service on December 4. Kim was indicted last month; prosecutors asked courts to merge the three men’s trials.

Because Yoon is already on trial as the alleged ringleader of insurrection — and now faces eight separate trials after the Supreme Court finalized a seven-year term for obstructing detention — prosecutors applied only the abuse-of-power charge in this indictment. Shin was indicted without detention; prosecutors viewed his involvement as less central than Kim’s.

The comprehensive team argued that spreading justification abroad was itself participation in insurrection by seeking international legitimacy for martial law.

Lee Eun-woo and the propaganda charge

Lee, former head of state-funded broadcaster KTV, was indicted without detention on insurrection propaganda. Prosecutors say he used his position to disseminate material defending the martial-law declaration in the days after December 3.

Lee had already been convicted in a separate abuse-of-authority case for ordering a subordinate on December 4 to delete news coverage critical of martial law; a first-instance court sentenced him to one year in prison, suspended for two years, in June 2026.

The propaganda charge depends on Kwon’s extended timeline: if the insurrection ended December 4, post-lifting broadcasts might not qualify.

Han Dong-hoon summons and the Dec. 4 meeting

The team also summoned former PPP leader Han Dong-hoon as a witness about a December 4 meeting at the prime minister’s residence involving ruling-party, government, and presidential officials. Han refused to appear, saying he had “no intention of helping a politically motivated investigation.”

If investigators treat the insurrection as ongoing on December 4, participants in that meeting could face scrutiny over whether discussions aimed to keep Yoon in office — even though martial law had already been lifted.

The Constitutional Court previously ruled in an impeachment case involving former Justice Minister Park Sung-jae that merely meeting at a presidential safe house after martial law ended was insufficient to prove insurrection involvement. Cho’s team had dismissed related safe-house allegations without indictment; Kwon’s team has pursued overlapping figures under its broader timeline.

Credibility concerns and what’s next

Legal experts quoted in Korean media warn that dueling conclusions between parallel special counsels could undermine public confidence in both probes and complicate ongoing insurrection trials.

Kwon’s team has been more aggressive — preparing to send roughly 50 people to trial, more than double the 24 indicted by Cho’s insurrection probe, according to earlier reports. The teams have clashed before over the Yoon arrest investigation and evidence handling.

With less than two weeks left on Kwon’s mandate, further indictments are expected, including figures linked to National Intelligence Service involvement in the insurrection and cases tied to Kim Keon Hee.

Discussion

1. Should blocking an impeachment vote ever be treated as part of an insurrection?

Kwon’s team argues the crisis continued until lawmakers removed Yoon. Critics say impeachment politics and violent subversion are different acts. Where would you draw the line?

2. Can two special prosecutors investigating the same event reach opposite conclusions without damaging the cases?

Cho and Kwon now disagree on a foundational fact. Does that help accountability — or make convictions harder to defend?

If you follow South Korean politics, how do you read the December 14 end date: a faithful reading of what insurrection means, or a tool to reach more defendants?
