The article is a part of a discussion about the meaning of logic in the area of law. The authors treating in a polemic way some common ideas and connotation of the term „legal logic“ – according to them there is a difference between a logic in a formal meaning, dealing with the structure of the nature language and methodology. In a situations, where formal logic seems to be insufficient to provide a solution of problems with the interpretation and/or application, correct methodology is only able to solve such problem. The authors of the outlined purposes briefly explicate core concepts, such as the normative system (as a set of relatively closed binding rules as defined segment of social relations), paying particular attention to the law system, further interpretative rules and methods (with interpretation, in general, is explaining the connection between the facts (actions) or the interpretation or clarification of the meaning of a particular text), logical consistency and inconsistency (a condition where the set of rules may or may not also draw the assertion and also a negation of this assertion). Inconsistency of normative texts can be either a logical inconsistency or methodological inconsistency. In addressing challenging legal matters, it is necessary to pass from the logic to the methodology, which, of course, logic and logical semantics remains necessary armature of reasoning.
