2. Determination

Therefore, we cannot accept this part of the argument of mistake of facts.

(2) The phrase “act that does not contravene social norms” as prescribed in Article 20 of the Criminal Act refers to an act that can be accepted in light of the overall spirit of legal order or the social ethics or social norms surrounding it. Thus, if a certain act satisfies the requirements such as the motive or legitimacy of the act, the means or method of the act, the reasonableness of the means or method, the balance of the legal interests of the protected interests and infringed interests, urgency, and supplement that there is no other means or method than the act, etc. (see, e.g., Supreme Court Decision 2004Do8530, Feb. 25, 2005). According to evidence duly adopted and examined by the court below, it is recognized that the defendant took a bath against the illegal left-hand turn of the victim.
