A recent trial court decision regarding former President Yoon Suk-yeol’s alleged defamation has brought to light significant differences in how two Supreme Court rulings concerning President Lee Jae-myung were applied. The core issue revolves around the legal principle of defamation and its application to statements made by public figures, particularly in the context of political discourse.
Key Differences in Supreme Court Precedents
The Seoul Central District Court’s Criminal Division 2, presided over by Judge Jo Sun-pyo, cited a Supreme Court ruling from May of the previous year (Supreme Court Case No. 2025do4697) six times in its judgment concerning former President Yoon. This specific ruling pertained to statements made by President Lee regarding the Seongnam Development Corporation and allegations of illegal golf outings. In that instance, the Supreme Court found certain statements to be factual falsehoods and remanded the case, effectively classifying them as defamation.
However, the trial court did not apply the legal reasoning from another Supreme Court ruling (Supreme Court Case No. 2019do13328) which acquitted President Lee in a separate defamation case. This discrepancy in applying precedents has become a central point of contention.
The Supreme Court’s Stance on Defamation and Public Statements
The Supreme Court’s 2025do4697 ruling, which was applied in the former President Yoon case, emphasized a comprehensive approach to determining whether a statement constitutes a factual falsehood. The court stated that when assessing the truthfulness of a statement, factors such as the overall context and intent of the speech, the objective content, the common meaning of the words used, and the coherence of the sentences should be considered. The ultimate criterion, the court advised, is the overall impression conveyed to the general public.
Furthermore, the Supreme Court indicated that when verifying the meaning of a statement, it is more important to consider how a general listener would have understood it based on the situation and overall context at the time of the utterance, rather than conducting a meticulous post-hoc analysis of individual expressions. The court also stressed the importance of considering whether the factual inaccuracy, if any, was significant enough to mislead the public’s accurate judgment of a candidate’s qualifications.
The trial court applied this principle to former President Yoon’s case, interpreting statements such as denying introducing a lawyer to former Yongsan District Office head Yoon Woo-jin and denying meeting with lawyer Kim Geon-hee and lawyer Jeon Seong-bae as factual falsehoods, based on the overall impression they would leave on the general public.
The Defense’s Argument and the Court’s Distinction
Lawyers for former President Yoon presented the Supreme Court’s 2020 ruling (Supreme Court Case No. 2019do13328) that acquitted President Lee as the basis for their argument for acquittal. This ruling concerned statements made by President Lee after the 2018 local elections, where he denied attempting to forcibly commit his brother to a psychiatric institution.
In that 2020 ruling, the Supreme Court held that statements made by a candidate during a debate or discussion, in response to questions or during arguments, cannot be punished as factual falsehoods unless there is a specific circumstance where the candidate deliberately and proactively presented false information with the intent to mislead, irrespective of the debate’s topic or context. The court reasoned that such statements are generally made within the flow of a debate, where spontaneity and time constraints can limit the clarity of expression.
The defense argued that the statements made by former President Yoon should be judged under the same principle, as they were also made in response to questions during a public forum.
The Trial Court’s Rationale for Distinguishing the Cases
However, the trial court ruled that the legal principle from the 2020 Supreme Court decision was not directly applicable to former President Yoon’s case. The court explained that the Supreme Court’s reasoning in the 2020 ruling was based on the specific context of candidate debates, where opportunities to speak, speaking order, and time limits are predetermined, ensuring a degree of balance and fairness among candidates. This structured environment, the court noted, inherently limits the precision of spontaneous remarks.
In contrast, the court distinguished the events involving former President Yoon. The debate where the statements about introducing a lawyer were made, although officially titled a ‘debate,’ was a special invitation where only former President Yoon was the candidate, and he was responding to panel questions. Similarly, the interview concerning the lawyer’s case was not a candidate debate at all.
Therefore, while acknowledging the common principle of considering the overall context of a statement from both Supreme Court rulings, the trial court concluded that the nature of a spontaneous exchange in a formal debate differs significantly from a one-on-one interview or a solo presentation responding to questions.
Ambiguity in Legal Standards
The differing interpretations also highlight concerns about the abstract nature of legal standards such as ‘overall impression’ and ‘the perspective of the general public.’ During the deliberation for the May ruling, Justices Lee Heung-gu and Oh Kyung-mi reportedly expressed dissenting opinions, arguing that statements that can be interpreted in multiple ways should be judged in favor of the accused.
As former President Yoon intends to appeal the initial ruling, the scope of applying the two Supreme Court precedents and the legal nature of the Guanhoon Club invitation debate are expected to be key points of contention in the appellate proceedings.
Conclusion
The legal battle surrounding former President Yoon Suk-yeol’s alleged defamation case underscores the complexities of applying legal precedents in cases involving public statements. The court’s decision to differentiate between structured candidate debates and other forms of public address, while referencing the overarching principle of considering the general public’s impression, demonstrates the nuanced approach required in defamation law. The outcome of the appeal will likely further clarify how these legal principles are applied in future cases concerning freedom of speech and defamation in the political arena.
