Hello. I am Attorney Lee Kyung-jun of Cheongchul Law Firm.

Insult crime (모욕죄) complaints have been rising sharply in Korea. Disputes at apartment residents' representative meetings, parent group chat rooms, internet comments, and live broadcasts have all become frequent triggers. Yet whether a given expression actually meets the threshold for criminal punishment has been judged inconsistently by investigators and courts.

Against this backdrop, the Supreme Court has issued a ruling that once again sets out clear standards for the limits of insult crime: Supreme Court Decision 2025Do3012, rendered on May 8, 2026 (대법원 2026. 5. 8. 선고 2025도3012 판결). The Court reversed and remanded a lower-court conviction concerning rough language used at an apartment residents' meeting, providing concrete criteria for what does and does not constitute insult crime. This article summarizes the facts, legal reasoning, and practical implications of the ruling.

1. Overview of the Case

The defendant, at an apartment residents' representative meeting and in front of other residents, directed remarks at the victim such as "Hey, hey, are we friends? Where does a young punk get off being so arrogant?" and was prosecuted for insult crime. The remarks came as the defendant expressed displeasure when the victim used informal speech (반말) toward him during the meeting.

The trial and appellate courts found the remarks to satisfy the elements of insult crime under Article 311 of the Criminal Act (형법 제311조) and convicted the defendant. The Supreme Court, however, held that the lower courts misapplied the law on insult crime and reversed and remanded the case.

2. The "External Reputation" Protected by Insult Crime

Article 311 of the Criminal Act provides that "a person who publicly insults another shall be punished by imprisonment for not more than one year, or by a fine not exceeding two million won." The legal interest protected by insult crime is generally explained as the social evaluation of a person's personal worth, i.e., "external reputation" (외부적 명예).

The key point is that what insult crime protects is external reputation, not subjective "feelings of honor" (명예감정). The mere fact that the listener felt subjectively offended or wounded does not, by itself, establish insult crime. The expression must objectively be capable of lowering the social evaluation of the other party before the elements of insult crime are met.

3. The Supreme Court's Standards for Judging Insult Crime

A. Objective and Strict Assessment

The Supreme Court held that whether an expression constitutes an "insult" under the insult crime statute must be judged not by the subjective feelings of the listener, but strictly by objective circumstances such as the relationship between the parties, the background to the expression, the manner of expression, and the surrounding situation, examining whether the expression is capable of harming the other party's external reputation.

Because insult crime is a criminal punishment provision, the Court made clear that punishment cannot turn on the listener's emotions alone. The same words may be evaluated differently depending on who the recipient is, the context in which they were uttered, and the tone and atmosphere of the exchange.

B. Rude or Minor Profanity Generally Does Not Constitute Insult Crime

Even more significant is the Court's standard for when expressions do not amount to insult crime. The Court held that absent special circumstances, an expression does not satisfy the elements of insult crime where it (i) does not seriously threaten an individual's personal rights, and (ii) is not a hateful expletive that destroys the listener's dignity, but is merely rude or impolite enough to make the listener uncomfortable, or amounts to a minor abstract expression or expletive used to convey negative or critical opinions or feelings (citing Supreme Court Decision 2019Do7370 of August 31, 2022, among others).

The Court also cited a Constitutional Court ruling, holding that in evaluating whether the elements of insult crime are met, courts should consider the overall content and context of the expression rather than dissected individual words, taking into account whether the expression was made impulsively, whether it was somewhat exaggerated, the background and nature of the conversation or debate, and the relationship between the speaker and the listener (citing Constitutional Court En Banc Decision 2012Heonba37 of June 27, 2013).

C. Discriminatory and Hateful Expressions Are Assessed Separately and Strictly

Notably, the Court did not simply hold that "minor profanity is not punishable." In the same ruling, the Court also expressly stated that even idiomatic or impulsive expressions may, in themselves, be recognized as capable of harming external reputation when they amount to aggressive, hostile, or contemptuous expressions of discrimination or hatred based on gender, race, ethnicity, disability, region of origin, sexual orientation, and the like.

In other words, even rough expressions of similar intensity may be treated differently depending on whether they are momentary and impulsive outbursts of anger, or expressions targeting the listener's identity or attributes through discrimination or hatred. This carries significant implications for the punishment standards for hate speech cases currently drawing social concern.

4. Why the Supreme Court Denied Insult Crime in This Case

Applying these principles, the Supreme Court found that considering the relationship between the defendant and the victim, the background to the remarks, the overall context, and the manner, meaning, and degree of the expression, the remarks in this case were merely a somewhat rough expression of discomfort about the victim's use of informal speech, and did not objectively constitute insulting conduct capable of lowering the social evaluation of the victim's personal worth.

The Court further explained that expressions venting the speaker's own dissatisfaction or anger, idiomatic, isolated, or impulsive expletives, and similar conduct that infringe on the listener's subjective feelings of honor or personal rights may give rise to civil tort liability, but cannot by themselves be deemed to constitute expressions lowering social evaluation that entail criminal responsibility. The Court emphasized that expressions amounting to momentary emotional outbursts may often be left to society's own self-evaluation and control mechanisms or regulated through civil liability, and that the exercise of criminal punishment power therefore requires caution.

5. The Practical Significance of the Ruling

Until now, insult crime cases have often been viewed through vague assumptions such as "if there is profanity, it is insult crime" or "if the victim claims humiliation, the defendant will be punished." As a result, ordinary disputes and emotional arguments have often escalated into criminal cases, and even sufficiently defensible matters have led to indictment.

This Supreme Court ruling has great practical significance because it organizes the elements of insult crime along three axes: (i) insult crime protects "external reputation," not "feelings of honor"; (ii) whether an expression amounts to insult must be judged strictly by objective circumstances, not by the listener's subjective view; and (iii) however, expressions based on discrimination or hatred may themselves constitute insult.

From a practical standpoint, the room to actively contest non-prosecution or acquittal in insult crime cases has widened considerably. Rather than isolating particular words and asking whether each is profane, defense practice must thoroughly analyze the overall context, background, the parties' relationship, the manner of expression, and tone to dispute whether the speech objectively lowered social evaluation. Conversely, complainants should not simply emphasize "I felt offended" but should specifically organize the context, the audience, and whether any element of discrimination or hatred was involved.

6. Key Items to Check in Insult Crime Cases

When advising clients in insult crime cases, the first thing to verify is the situation, audience, and tone in which the disputed expression was made. Simply describing "these words were used" is not enough. In light of the Supreme Court's standards above, the following items should be organized together with objective evidence.

① The time, place, and nature of where the expression occurred (official meeting, private gathering, online space, etc.); ② what conversation or conduct preceded the expression and the context in which it arose; ③ the speaker's tone, expression, and gestures; ④ the scope of the audience and how they perceived the expression; and ⑤ whether the expression contains elements of discrimination or hatred are the central items for review.

In addition, insult crime is a complaint-based offense (친고죄) that requires the victim's complaint for prosecution, and procedural requirements such as the six-month complaint period (from the day the offender becomes known) are strict. These factors must be considered together when setting the direction of the case.

7. Conclusion

This Supreme Court ruling clearly rejects the simplistic view that "any expression containing profanity is insult crime," and requires practitioners to reexamine the scope of insult crime with precision. At the same time, the ruling should not be read as meaning "minor profanity is never punishable" — when an expression contains elements of discrimination or hatred or reaches a level that destroys the listener's dignity, it may still be punished as insult crime.

Insult crime cases are an area where everyday disputes can quickly escalate into criminal matters, and once a case is filed, its trajectory tends to harden. If you have been charged with insult crime, or conversely if you have suffered harm from insulting remarks, it is important to consult with a criminal defense attorney (형사전문변호사) as early as possible, examine your case carefully against the standards of this Supreme Court ruling, and set the right direction of response.
