Spanish Abstract: El ensayo aborda la cuestion de la justicia constitucional con el fin de superar los modelos historicos norteamericano y europeo, presentando la tesis segun la cual cada modelo de justicia constitucional es diferente de otro, si bien dos modelos pueden presentar caracteres comunes y ser semejantes a los historicos. Diferentes tradiciones y culturas legales de hecho van a influir sobre los rasgos caracteristicos de la justicia constitucional en los diferentes Paises del mundo. Desde esta perspectiva, nos preguntamos si hay factores clave que no varian en los diferentes sistemas de justicia constitucional y la forma en que puede ayudar el uso de la metodologia comparativa funcionalista.English Abstract: The paper attempts to address the issue of constitutional justice in order to overcome the historic American and European models, presenting the argument that each model of constitutional justice is different from another: that could happen even if two models may have common characteristics and be similar to those historical. Different legal traditions and cultures made will influence the characteristics of constitutional justice in different Countries of the World. From this point of view, we wonder if there are basic elements that do not vary in some different systems of constitutional justice and how it can help our analysis the use of functional method of comparative law.
