Matthew H. Kramer (University of Cambridge; University of Cambridge - Faculty of Law) has posted Puzzles And Disagreements: Responses to "Legal Positivism in the Civil-Law Tradition" on SSRN. Here is the abstract:
This essay is written for a volume Jurisprudence in the Mirror, edited by Michael Green. It responds to a paper by Cristina Redondo Natella and Giovanni Battista Ratti in which they outline the contemporary debates among legal positivists in Continental Europe and Latin America. Among the main foci of my responses are some matters of meta-ethics, the nature of legal positivism, the distinction between deontic conflicts and contradictions, the property of legal validity, and the character of legal interpretation.
