Can you believe that a former president was sentenced to life imprisonment for treason in a South Korean court? On February 19, 2026, that unbelievable moment became reality, with Judge Ji Gui-yeon at its heart. The 25th Criminal Division of the Seoul Central District Court ruled in former President Yoon Seok-yeol’s case that beyond the superficial measure of declaring “martial law,” the exercise of force with the purpose of obstructing and paralyzing the functions of the National Assembly constituted treason aimed at subverting the national order under criminal law.

This ruling left a strong impression because Judge Ji Gui-yeon clearly distinguished between ‘motive’ and ‘purpose.’ Arguments like overcoming a national crisis are merely motives, which cannot justify the illegal purpose of undermining constitutional order by, for example, shutting down the National Assembly. The phrase featured in the verdict, “You cannot steal candles simply because you claim to be reading the Bible,” succinctly encapsulates this logic, ensuring that readers (and the public) grasp the core issue intuitively.

Another crucial point was the direct answer to the age-old question, “Can a president be held liable for treason?” Judge Ji Gui-yeon traced the evolution of legal systems from Roman times to modern sovereign states, establishing as a legal principle that it is not the individual holder of power but any act that infringes on the nation’s fundamental order and parliamentary sovereignty that is subject to punishment. As a result, this case transcended a simple guilty verdict, marking a landmark ruling reaffirming the principles of power checks and accountability in Korean constitutional history.

The Core of Judge Ji Gui-yeon’s Treason Ruling: Distinguishing Justification from Purpose

“You cannot steal a candle just because you are reading the Bible.” This sentence, cited by Chief Judge Ji Gui-yeon in her ruling, is not merely a metaphor but a condensed expression of the crucial standard that determines the establishment of treason. The reason readers pause at this statement is clear: even if someone’s words seem plausible, the principle that an act cannot be justified once it exceeds the law strikes intuitively.

Chief Judge Ji’s logic can be summarized in one sentence: Justification (motive) and purpose (intended outcome) are different, and treason is judged not by ‘noble words’ but by the ‘actual intended purpose.’ Claims such as overcoming national crises or restoring order can be motives. However, the court holds that regardless of the motive, if force was exercised to obstruct or paralyze the function of the National Assembly, it meets the criminal law’s definition of intent to disrupt the constitutional order.

This distinction is also what determines the persuasiveness of the ruling. Political rhetoric or crisis discourse can always appear, but the law returns to these questions:

• What was the justification presented outwardly?
• What was the real purpose sought to be achieved?
• What kind of ‘force’ was exercised to achieve that purpose?

Ultimately, the candle metaphor targets one point: No matter how noble the justification may be, if the means and purpose undermine the constitutional order, the judgment of crime does not change. At this juncture, Ji Gui-yeon’s ruling pulls treason out of abstract political controversies and reanchors it within a legal framework of purpose, act, and effect.

Exploring with Ji Gui-yeon: Can a President Commit Treason? A Legal and Historical Deep Dive

From ancient Rome to the modern era, the question of “Can those in power be guilty of treason?” has served as more than mere legal text interpretation—it has acted as a mirror reflecting the structure of political systems. The responsibilities of kings, emperors, and presidents may seem similar but have crucially evolved. This is precisely why Chief Judge Ji Gui-yeon extensively invoked historical context in her ruling.

An Era When Power Was Identical to the State: “Opposing the Emperor Is Opposing the State”

In ancient Rome, crimes equivalent to treason targeted acts disrupting the fundamental order of the state. However, during the imperial era, the perception that the state and the monarch were one grew stronger, leading to rebellion against the emperor being equated with crimes against the state. At that time, the very idea that “the ruler himself could undermine state order” was nearly inconceivable—the state’s face was the ruler.

The Medieval Misconception: The Idea That “The Monarch Cannot Commit Treason”

Moving into the medieval period, another fallacy emerged. As the premise of the king embodying the state strengthened, paradoxically, the notion that the king could not be the subject of rebellion or treason took hold. In legal terms, those who disrupted state order were considered “enemies outside the state,” and the monarch was inherently excluded from this category. This idea risked functioning more as a justification for power abuse than as a punishment mechanism.

The Modern Shift: Sovereignty Moves from “King” to “People and Parliament”

The 18th and 19th centuries brought a fundamental change. The idea that sovereignty was not ‘vested’ in the king but delegated from the people became established, and parliament became more than an advisory body—it became the institutional embodiment of sovereignty. From this point, whether king or president, actions that attack or paralyze parliamentary functions could be interpreted as violations of sovereignty. In other words, those in power were no longer the state itself but temporarily entrusted with exercising state authority.

Chief Judge Ji Gui-yeon’s Verdict: “A President Can Also Commit Treason”

Building on this historical trajectory, Chief Judge Ji Gui-yeon decisively broke the long-standing belief that a president cannot be the subject of treason. The core argument is unambiguous:

• Treason is established not by status but by purpose and action.
• Especially, the use of force to obstruct or paralyze the parliament’s function can constitute treason aimed at disrupting the constitutional order.

Ultimately, in a modern democracy, the responsibility of those in power does not lighten with greater authority—instead, it is held to stricter standards precisely because of their power. Whether king or president, the moment they shake the fundamental order of the state, their position no longer grants immunity but grounds for accountability.

The Power of Investigative Authority and Evidence: The Boundary Between Legitimacy and Trust—The Standard Set by Judge Ji Gui-yeon

In cases where investigative authority clashes among the Corruption Investigation Office (CIO), prosecutors, and the police, judgments risk being swallowed by “procedural disputes.” Yet, Chief Judge Ji Gui-yeon did not center her ruling around the battle over jurisdiction. She changed the question. Instead of who conducted the investigation, she shifted the trial’s focus to what was proven and how convincingly.

The core was twofold. First, she recognized the CIO’s authority to investigate charges of insurrection, thereby establishing a foundation of procedural legitimacy. This laid the legal groundwork so that disputes over jurisdiction would not directly invalidate evidence. Second, more decisively, she drew a clear line by stating that “even excluding the CIO’s investigation,” the evidence secured by the prosecutors and police alone suffices for a guilty verdict. This layered approach to evidence prevented jurisdictional conflicts from becoming a ‘single switch’ that could dismantle the entire ruling.

This approach holds significant meaning for building trust in trials. As jurisdictional battles intensify, the public tends to interpret verdicts as “a win for one institution over another.” However, Judge Ji’s ruling grammar places front and center the court’s process of reaching truth through evidence rather than institutional power struggles. Ultimately, the conclusion in this section is simple: no matter how fierce the dispute over investigative authority, a guilty verdict stands firm when evidence is thorough and independently corroborated—a boundary this trial scene clearly demonstrated.

The Historical Significance of the Ji Guiyeon Ruling and the Future of Democracy: A Warning and Promise for the Rule of Law

Beyond a simple guilty verdict, the Ji Guiyeon ruling poses a profound question: what truly sustains democracy? When the language of power is cloaked in the pretext of “crisis response,” how far can the law permit such justification? The message this case sends is clear: no one has the authority to halt the constitutional order simply because the rationale sounds plausible.

Judging the ‘Purpose’ Behind Actions Targeting the Core of Democracy

The historical significance of this ruling lies not in the outcome (life imprisonment), but in how the nature of the act was defined. Chief Judge Ji Guiyeon held that even if emergency measures were formally adopted, if their substance was an exercise of force aimed at obstructing or paralyzing the National Assembly’s function, then the crime of rebellion with the intent to disrupt the constitutional order is established. This cuts off the dangerous misconception that “power exercised with procedural formality can be justified.” Democracy does not stand on formality, but rather on operational checks and balances—a declaration close to this.

Institutional Implications of "The President is No Exception"

The Ji Guiyeon ruling historically reaffirmed that the president’s position cannot serve as immunity that lessens responsibility. It heralds two shifts in South Korea’s judicial history:

• Setting a benchmark for cases involving powerful figures: Even for cases involving the highest authorities, precedents accumulate emphasizing judgment based on legal elements before “political interpretation.”
• Strict boundaries against violations of the constitutional order: When frameworks of national crisis such as martial law or emergency measures arise, attempts to paralyze democratic institutions (especially the National Assembly) will face quicker and stronger legal condemnation.

A Message from the Judiciary: From Punishment to ‘Language of Prevention’

The deepest resonance this case leaves in Korean society is not “who won” but “what changes next.” The Ji Guiyeon ruling reestablished the crime of rebellion not as a relic of the past but as a legal tool to control present dangers. Democracy can be shaken at any moment, but the moment its shaken state is buried under the label “crisis,” it collapses even further. This ruling precisely pinpoints that moment and demonstrates that Korea’s rule of law can renew itself.
