The topic of this article is the strong theory of social rights, which is described as an unifying theory on the grounds, the normative structure and the procedures for protecting different types of rights and, in particular, social rights and liberty rights. Some aspects of that theory are criticized, namely, some of its moral assumptions, its political and constitutional consequences, its troublesome economic effects, the way it presents the normative structure of rights which is considered flawed, and the model of judicial guarantee proposed for social rights which it is said to be counterproductive.
