2. Determination

A. Determination of misunderstanding of facts and misapprehension of legal principles regarding the crime of obstruction of the performance of official duties: (a) the purport of the crime is to recognize the fact that the other party is a public official who performs his/her duties, and that violence or intimidation is made against it; (b) its recognition is so-called “unwritten intention” even if it is uncertain; and (c) it does not require any intent to interfere with the performance of his/her duties (see, e.g., Supreme Court Decision 2010Do11381, May 24, 2012). According to the statements made by the damaged public official in an investigative agency and the on-site documentary evidence image corresponding thereto, even though the fact that the damaged public official is a public official performing the duties of the office building, it may be recognized that the Defendant committed an assault by priceing the chest part or by hand with the right snow part of the building, and thus, this part of the allegation of facts is without merit, and thus, it does not constitute a legitimate act in light of social ethics or social norms.
