South Korea Appeals Court to Rule on Ex-President Yoon Suk Yeol’s Martial Law Case on January 26 After Prosecutors Again Seek Death Penalty

Introduction

A Seoul appeals court will deliver its verdict on January 26 in the insurrection case against former President Yoon Suk Yeol, setting a date for the ruling that will decide whether South Korea’s most serious punishment for a leader who turned the military on his own parliament is life in prison or death. The Seoul High Court announced the date on Thursday, November 5, after closing arguments in Yoon’s appeal concluded, bringing the long legal reckoning over his failed December 2024 martial law declaration to the edge of its final judgment. Prosecutors have again demanded the death penalty, arguing that the life sentence imposed at the first trial was too lenient for a president who, in their case, tried to seize the legislature, arrest his opponents and rule without check. Yoon, in a final statement lasting one hour and twenty minutes, told the court that his declaration was a constitutional power, not an insurrection, and that a decree that ended within hours without a single injury cannot be punished as a rebellion. The case has already produced one of the most consequential verdicts in South Korean democratic history, and the appeal now asks three judges to decide whether the first court’s reasoning survives — and whether its mercy does too. That is the question at the heart of the Yoon Suk Yeol martial law appeal verdict January 26 death penalty November 2026 case now heading for its final ruling.

1. What the Seoul High Court decided on November 5

1.1 The January 26 verdict date

The Seoul High Court said on Thursday, November 5, that it will deliver its verdict on January 26, 2027, at 2:30 p.m., in the insurrection case against the former president. The announcement came as the appeal proceedings reached their closing stage, with the court’s Criminal Division 12-1 hearing the final arguments from both sides. The date gives the panel, presided over by high court judges Lee Seung-cheol, Cho Jin-gu and Kim Min-a, nearly twelve weeks to weigh a record that spans the night of the declaration, the first trial’s reasoning and the prosecution’s renewed demand for the maximum sentence. Yonhap reported the announcement the same day, and Korean court reporting confirmed that the verdict date was fixed only after Yoon delivered his final statement to the court. For a case that has moved through investigation, indictment, detention, trial and appeal in less than two years, the January date is the last scheduled milestone before the appellate ruling itself.

1.2 What the panel said about the timetable

The court’s decision to fix the verdict date at the close of the November 5 hearing follows the ordinary course of a major South Korean appeal, in which the panel sets the ruling date once closing arguments and the defendant’s final statement are complete. No further hearings are scheduled before the verdict, and the January 26 date now frames everything that follows: the prosecution’s case, the defence’s answer and the court’s own judgment on whether the first trial was right. The panel has not indicated that it will take further evidence, and the reporting from Seoul describes the case as closed to new argument until the ruling is handed down. That timetable matters because the appeal is not a retrial of the facts alone; it is a test of whether the district court’s conclusion — that deploying troops to the National Assembly amounted to leading an insurrection — holds under the prosecution’s challenge to the sentence and the defence’s challenge to the conviction itself.

2. The death penalty demand, renewed

2.1 What special counsel Cho Eun-suk argued

The special counsel team led by Cho Eun-suk renewed its demand for the death penalty for Yoon on October 29, at the Seoul High Court, repeating the same request it made at the first trial. The prosecution said there was, in its words, no reason to hesitate and no room for misjudgment of the facts, presenting the case as the highest level of treason and arguing that the life sentence handed down in February was too lenient for the ringleader of an insurrection. The demand was made during closing proceedings in the appeal, and it was reported the same day by Yonhap and the Korea Herald. It is the second time prosecutors have asked a court to sentence a former South Korean president to death for the martial law declaration, and the second time they have framed the case as one in which only the maximum penalty fits the crime charged.

2.2 Why prosecutors say life was too lenient

The prosecution’s argument is built on a direct challenge to the three findings that led the first court to choose life imprisonment instead of death. The district court had found that the martial law operation did not appear meticulously planned, that it ended quickly, and that the use of force was restrained — and on those grounds it spared Yoon the death penalty. The special counsel team challenged all three findings in the appeal, arguing that the brevity of the decree and the restraint shown on the night do not diminish the gravity of what was attempted. In the prosecution’s account, Yoon declared emergency martial law on December 3, 2024, and deployed soldiers and police to the National Assembly with orders to seize the legislature, arrest political opponents and establish unchecked rule. That account, if accepted in full, is the prosecution’s case for why the sentence should be raised rather than confirmed.

3. Yoon’s final statement: martial law as a constitutional power

3.1 The 80-minute address to the court

Yoon used his final statement at the closing hearing on November 5 to make his case directly to the three judges, speaking for one hour and twenty minutes. He told the court that his martial law declaration was an exercise of a constitutional power, not an insurrection, and that the decree must be judged as a presidential act rather than as a rebellion. Korean press reporting of the hearing describes a detailed address in which the former president defended the declaration as a lawful response to what he has called anti-state forces, and insisted that the operation was never intended to overthrow the constitutional order. The statement was the last word from the defendant before the panel retired to consider its verdict, and it closed a hearing that had already heard the prosecution’s renewed demand for his execution.

3.2 The defence case: two hours, no injuries

The core of the defence argument is that a martial law declaration that ended in just two hours, without a single injury, cannot be punished as an insurrection. The defence has argued that the decree was lifted after the National Assembly voted against it, that no one was harmed in the operation, and that the absence of violence or sustained seizure of power means the legal elements of insurrection were never met. That framing stands in direct opposition to the prosecution’s case, which treats the intent and the orders given on the night as the crime, regardless of how quickly the attempt collapsed. The appeal judges must now decide between those two readings of the same night: a failed and bloodless decree that never became a rebellion, or an attempted seizure of power that failed only because the legislature and the public resisted it.

4. The night of December 3, 2024

4.1 The declaration and the troops at the National Assembly

On the night of December 3, 2024, Yoon declared emergency martial law in a late-night televised address, deploying soldiers and police to the National Assembly in Seoul. Prosecutors say the troops were sent with orders to seize the legislature, arrest political opponents and establish unchecked rule, and they have built their case on the orders given and the movements of forces that night. Yoon justified the declaration at the time as a measure to eliminate what he called anti-state elements, a claim his critics have always rejected as a pretext for holding on to power. The images of soldiers entering the parliament building and of lawmakers pushing past troops to vote became the defining pictures of the crisis, and they remain the central evidence in a case that turns on what the president intended when he gave the order.

4.2 How the six-hour martial law ended

The martial law decree did not survive the night. Lawmakers gathered at the National Assembly and voted to lift it, and the decree was withdrawn within hours, ending the shortest martial law declaration in South Korean history. Yoon was impeached by the National Assembly on December 14, 2024, and removed from office by the Constitutional Court in April 2025. He was indicted and detained in January 2025 on charges of staging a riot with the aim of subverting the constitution, including by declaring emergency martial law and deploying troops to the National Assembly. The speed of the decree’s collapse is now doing double work in the case: the defence cites it as proof that no insurrection occurred, while the prosecution cites it as proof only that the attempt was thwarted.

5. The first trial: conviction and life imprisonment

5.1 The February 2026 verdict

On February 19, 2026, the Seoul Central District Court found Yoon guilty of leading an insurrection and sentenced him to life imprisonment. The court found that the deployment of troops to the National Assembly met the elements of insurrection — the purpose of subverting the constitution and the staging of a riot — and convicted the former president as its ringleader. It was the first time a former South Korean president had been convicted of leading an insurrection, and the verdict closed a trial that had examined the orders, the troop movements and the president’s stated reasons for the decree in exhaustive detail. Yoon appealed the conviction, and the case moved to the Seoul High Court, where the prosecution has now asked the appellate panel to replace the life sentence with death.

5.2 Why the court chose life over death

Prosecutors had sought the death penalty at the first trial as well, and the district court chose life instead. Its reasoning rested on three findings: that the operation did not appear meticulously planned, that martial law ended quickly, and that the use of force was restrained. Those findings did not acquit Yoon — the court still convicted him of the most serious charge available — but they drew a line between the crime and the maximum punishment. The special counsel team has now challenged all three findings on appeal, arguing that none of them justifies sparing the ringleader of an insurrection. The appellate panel’s verdict on January 26 will show whether it accepts that challenge, and whether the life sentence survives or is replaced.

6. The co-defendants and the separate drone case

6.1 Kim Yong-hyun and Noh Sang-won

Yoon was not the only defendant in the case. The special counsel team also sought life imprisonment for former Defense Minister Kim Yong-hyun and a 30-year prison sentence for former Defense Intelligence Commander Noh Sang-won over their alleged roles in the martial law operation. Both were indicted alongside Yoon on charges including performing important duties in an insurrection, and their fates are tied to the same verdict date. The prosecution’s case treats the operation as a coordinated effort in which the president gave the orders and his senior officials carried them out, and the sentences it has sought reflect that hierarchy: death for the ringleader, life for the defence minister, and thirty years for the intelligence commander.

6.2 The 30-year drone incursion term

Separately, the special counsel is seeking a 30-year prison term for Yoon over alleged drone incursions in 2024 that prosecutors say were meant to provoke North Korea and create a pretext for martial law at home. That case runs alongside the insurrection appeal and adds a second front to the former president’s legal exposure, alleging that the groundwork for the December decree was laid months earlier through operations designed to heighten tensions across the border. The wider investigation continues as well: the Serious Crime Investigation Agency and police have formed a joint team to pursue unresolved cases tied to the martial law bid, and a three-year prison term has been finalised for a former security chief who blocked Yoon’s arrest. The legal reckoning, in other words, extends well beyond the one defendant and the one night.

7. What a death sentence would mean in practice

7.1 The three penalties in the criminal code

Under South Korea’s criminal code, the ringleader of an insurrection faces only three possible penalties: death, life imprisonment, or life imprisonment without forced labour. There is no lesser sentence available for the charge, which is why the prosecution’s demand and the defence’s plea for acquittal sit so far apart. If the Seoul High Court accepts the prosecution’s case in full, the choice it faces is the starkest in Korean criminal law. If it upholds the first trial, Yoon remains in prison for life. The code leaves the panel no middle ground, and that rigidity is part of why the January verdict carries such weight: the court must either confirm a life sentence, impose a death sentence, or acquit a man already convicted of leading an insurrection.

7.2 South Korea’s execution moratorium since 1997

Even if the court imposed the death penalty, an execution is unlikely in practice. South Korea has not carried out an execution since December 1997 and effectively maintains a moratorium, and the country is widely regarded as abolitionist in practice even though capital punishment remains on the statute books. That reality does not make the prosecution’s demand symbolic — a death sentence would still be the heaviest judgment a Korean court can pass, and it would place Yoon among the condemned rather than the merely imprisoned — but it does mean the practical difference between the sentences the court can impose is narrower than the legal difference. The debate over the penalty is therefore as much about the historical record as about Yoon’s fate: whether the courts will record a president’s attempt to seize power as a crime deserving of death, or as one deserving of life behind bars.

8. What remains unconfirmed and what to watch next

8.1 The questions the verdict will answer

The January 26 verdict will answer the questions that have defined the appeal. It will show whether the panel accepts the prosecution’s challenge to the three findings behind the life sentence, and whether it agrees that the sentence should be raised to death. It will show whether the defence’s argument — that a decree which ended within hours without injury cannot be an insurrection — persuades the court to overturn the conviction or reduce the sentence. And it will determine the fates of Kim Yong-hyun and Noh Sang-won, whose sentences were argued alongside Yoon’s. None of those outcomes can be predicted from the closing hearing alone, and the panel has given no public indication of its direction.

8.2 What to watch next

The date to watch is January 26, 2027, at 2:30 p.m., when the Seoul High Court hands down its ruling. After that, either side is expected to be able to take the case to the Supreme Court, and the drone incursion case and the joint investigation team’s work will continue regardless of the appeal’s outcome. The political consequences will also be watched closely: the martial law crisis reshaped South Korean politics, ended a presidency and produced a trial without precedent, and the final sentence will become part of how the country remembers it. The coming weeks will provide the answers.
