Reflexiones sobre los conceptos de validez y existencia de las normas jurídicas
Abstract: The he aim of this work is to analyze some of the issues raised by the concepts of validity and existence of the rules in the legal order. About validity, I maintain that the multiple meanings that such a notion has in legal theory could be eliminated in favour of the concept of validity as legality. In this sense, a statement on validity is an interpretative one, and, in many cases, it has a value nature. Unlike the validity (which is a feature that the rules may or may not have), the existence poses a different question: to determine under what conditions it can be said that we have a legal rule or, to put it another way, when a legal rule exists. For this purpose, I analyze two concepts on existence: formal existence and conventional existence.
