Anyone who defames another by publicly alleging facts can be punished, even though the facts are true. Because In korean criminal law there are the article, “A person who defames another by publicly alleging facts shall be punished by imprisonment or imprisonment without prison labor for not more than two years or by a fine not exceeding five million won(Art. 307 (1))”. Furthermore, “A person who defames another by publicly alleging false facts shall be punished by imprisonment for not more than five years, suspension of qualifications for not more than ten years, or a fine not exceeding ten million won(Art. 307 (2))”. But If the facts alleged under Article 307 (1) are true and solely for the public interest, the act shall not be punishable(Art. 310). However, there is no rule about the unsettled facts(It’s not sure whether the publicly alleging facts is true or false). In practice, this cases are applied to Art. 307 (2). And the practice deal with the unsettled facts in the field of a mistake of face. But in Art. 307 (2) the “fale facts” is a element of a crime, so that the unsettled facts should be applied not to Art. 307 (2), but Art. 307 (1). Otherwise, the unsettled facts can make misunderstand to the public by the guilty or not guilty of a judge. Because if the judge found the defendant guilty, then the unsetlled fact turn to be a true fact in spite of not proving of the fact. But if the judge found the defendant not guilty, then the unsettled fact turn to be a false fact. Therefore, if a judge can not prove the truth of the unsettled fact, then the Art. 307 (1) must be applied.
