Some legal theorists deny that states can conceivably act extra-legally, in the sense of acting contrary to domestic law. This position finds its most robust articulation in the writings of Hans Kelsen, and has more recently been taken up by David Dyzenhaus in the context of his work on emergencies and legality. This paper seeks to demystify their arguments and, ultimately, contend that we can intelligibly speak of the state as a legal wrongdoer or a legally unauthorized actor.

This paper investigates the relations between the concepts of moral harm and moral responsibility, arguing for a circularity between the two. On this basis the conceptual soundness of descriptivism, on which consequentialist and non-consequentialist arguments are often grounded, is questioned. In the last section a certain version of ascriptivism is defended: The circularity is relevant in order to understand how a restricted version of ascriptivism may in fact be well founded.
