All contents of the article written by the Defendant by misunderstanding of facts and legal principles are not false, but the Defendant believed that the content of the article was true at the time, and there was considerable reason to believe that it was true, and also prepared the article for the public interest, and therefore there was no purpose to slander the victim, and thus, each crime against the Defendant is not established in the judgment of the court below.

B. The sentence of the lower court’s improper sentencing (an amount of KRW 3 million) is too unreasonable.

2. Determination
