Andrea Faggion (State University of Londrina) has posted Law and Moral Justification on SSRN. Here is the abstract:
Many prominent legal philosophers believe that law makes some type of moral claim in virtue of its nature. Although the law is not an intelligent agent, the attribution of a claim to law does not need to be as mysterious as some theorists believe. It means that law-making and law-applying acts are intelligible only in the light of a certain presupposition, even if a lawmaker or a law-applier subjectively disbelieves the content of that presupposition. In this paper, I aim to clarify what type of moral claim would be suitable for law if law were to make a claim to be morally justified. I then argue that legal practice is perfectly intelligible without moral presuppositions — that is, that the law does not necessarily make moral claims.
