Each legal regulation must contain content. How to prescribe a service for regulating relationships between people must be expressed over time. Regulations are expressed using forms that are defined in both social culture and the legal order. In the legal order, as well as in the social culture, expression has differentiated itself. Given the need for nomotechnics, it can be classified into these areas: linguistic expression, logical expression, political interpretation, and credible interpretation in the right regulations. Linguistic interpretation through the understanding of words, their interconnections are exchanged to find out the general content, but also the very meaning of the legal rule. For linguistic interpretation, we can also say that it is an initial interpretation that the moralist must use if he wants to find out the meaning and content of legal norms. Legal regulation must be meaningful that it should not be opposed to logical reasoning. Legal logic is the means by which logical operations create a rule of law and are interpreted correctly by logical reasoning. Right is not an end in itself, as has sometimes been claimed in literature. It is the right instrument for achieving the goals of social policies. It is generally probable that the interpretation of the law could be defined as the interpretation of certain provisions of the law, due to the error of misinterpretation in practice, which, at the proposal of the authorized proponents, was passed by the legislator or the legislature. is credibly interpreted. On June 19, 2015, the Croatian Parliament adopted Uniform Rules that seek to ensure a uniform methodology, to properly use and equalize the expression in the acts adopted by the Croatian Parliament.
