Moral Principles and Legal Validity

Two recent high‐quality articles, including one in this journal, have challenged the Inclusivist and Incorporationist varieties of legal positivism. David Lefkowitz and Michael Giudice, writing from perspectives heavily influenced by the work of Joseph Raz, have endeavored—in sophisticated and interestingly distinct ways—to vindicate Raz's contention that moral principles are never among the law‐validating criteria in any legal system nor among the laws that are applied as binding bases for adjudicative and administrative decisions in such a system. The present article responds to their defenses of Raz's Exclusive Legal Positivism.
