This vague of norm sparks the different decisions affecting the subject in a family, and such a difference inflicts uncertainty on whether a decision is deemed valid or invalid from the outset when it is linked to Article 197 of Act Number 8 of 1981 concerning Criminal Code Procedures. Keywords: criminal offense, domestic violence, family scope
