After the revision in 2013, the crime of indecent assault in the Military Criminal Act only punishes indecent behavior between male and female soldiers. The majority opinion interprets anal sex according to the ordinary meaning of the word, and since anal sex is an act that can be performed between opposite sexes, it is not limited to acts between men. In other words, the language of the current regulation cannot be interpreted as a regulation punishing the sexual act itself between soldiers of the same sex. However, the opposing opinion interprets the current regulations as still punishing abnormal sexual behavior between male soldiers. In the end, the terminology change to anal intercourse gave room for different interpretations of the meaning of the norm, making the constituent requirements more ambiguous. As a specific example, anal sex itself should contain judgment guidelines for the interpretation of general provisions, but anal sex does not fulfill its function as a specific example for the interpretation of indecent act. In particular, the crime of indecent conduct under the Military Criminal Act does not limit the means or methods of indecent conduct. Thus, indecent acts by mutual agreement not accompanied by coercion can also be subsumed. However, considering the intention of the victim or the sexual moral concept of the times, sexual acts between the same sex themselves cannot be considered indecent. Also, in a sexual act by mutual consent, the actor and the victim cannot be determined. In the Military Criminal Act, the provision of indecent offense is not clear. Although the concepts of anal intercourse and indecent act were used as elements of the crime, in particular, the term indecent act was used, but the necessity and degree of coercion were not clearly defined. It is required that the constituent elements subject to criminal punishment be specifically and clearly defined using a clear and unexpandable concept as much as possible. If the constituent elements of a crime consist of an abstract or ambiguous concept, or if the scope of application is too broad and comprehensive to be unclear, the public will not be able to know what the act is prohibited by law. Ambiguous legal regulations cannot perform a general preventive function, and only increase the possibility of arbitrary interpretation by judges.
