In her paper, Rundle seeks to develop a normative legal theory that is distinctively public. Building on her book, Forms Liberate, she seeks to bring Fuller’s legal theory into conversation with Arendt’s political theory. In this comment, I present some hesitations with regard to the fruitfulness of this conversation. It concludes with the suggestion to explore how Radbruch’s ‘idea of law’ could be fruitful for the overall jurisprudential project Rundle seeks to develop in her work.

Jeff McMahan, one of the leading contemporary writers on ‘just war thinking’, argues in the book under review, Killing in War, that one of the central tenets of the ‘ius in bello’, namely the moral equality of combatants, is both conceptually and morally untenable. This results from a reflection upon and a departure from two basic assumptions in Walzer’s work, namely the idea that war itself isn’t a relation between persons, but between political entities and their human instruments and the idea that the ‘ius ad bellum’ and ‘ius in bello’ are and should be kept distinct. This book merits serious reflection. However, the disadvantages of McMahan’s position are obvious. If the rights of combatants during war depend on the justice of their cause, the immunity of the civilians on the side of the supposed ‘unjust’ enemy is seriously endangered.
