"This book uses Niklas Luhmann's systems theory to explore how the legal system operates as one of modern society's subsystems. The authors demonstrate how this theory alters our understanding of some of the most important and controversial issues within law: the nature of judicial communication and legal argument; the claim that it can be right to disobey law; the character of legal pluralism and globalisation; time and its construction within law; the significance of the rule of law and human rights and the role of appeals to, and within, law"--P.
