This chapter examines how laws, constitutions, and federalism provide structure to the context of political life. It first considers the importance of constitutions in determining the basic structure of the state and the fundamental rights of citizens that they establish before asking whether the Universal Declaration of Human Rights is Western-centric. It then explores different ways in which states may attempt to realize justice in applying the law, with particular emphasis on differences between Islamic and Western practice. It also discusses the importance of constitutional courts, the ways that the institution of federalism contains the powers of the state and manage diverse societies, and consociationalism as an alternative approach to managing such diversity. Finally, it comments on the increasing legalization of political life.
