Does law have moral value? Is there a moral obligation to obey the law? According to the author, these questions characterize the problem of normativity of law –understood as that of its moral value– which, together with the problem posed by the concept of law, constitute the questions which philosophy of law has traditionally dealt with. The author holds that raising these questions –as a legal ... [Show full abstract] philosopher– makes no sense as they are pseudo-problems, because the question respecting the moral obligation to obey the law must be answered by moral philosophy, rather than by legal philosophy as it is a problem which lies within the sphere of the former discipline and not the latter. The author makes a clear distinction between the concept of moral validity and another concept of legal validity (applicability), and comes to the conclusion that legal norms possess only legal, not moral validity. He claims that theory of law lacks an answer to the problem of applicability of law, only answering that of its identification, because legal obligations, unlike moral obligations, do not constitute conclusive reasons for action.
