Abstract: Normative concepts can play a crucial role in modelling the be- haviour of artificial agents, such as robots. The law may have a prominent role in this regard. Since the law changes in time, tempo- ral aspects of legal dynamics must be considered in reasoning. This paper offers a critical review of recent contributions in the field.
