Abstract

Take two positions, both of which we take to be popular ways of thinking about law. First, some norm N is part of the law only if, and in virtue of, N being ultimately recognized or validated by the rule of recognition. Call this Hartian Orthodoxy. Second, statements about legal rights are best understood as claims about the existence of moral rights according to law. Call this legal perspectivalism. Here we show that the two are incompatible. Our argument is that, to account for certain arguments that mix legal and factual claims, perspectivalism must close the legal perspective according to some inference rule. As it happens, however, the only defensible candidates render perspectivalism incompatible with Hartian Orthodoxy.
