This chapter highlights the practice of constitutionalism in hybrid regimes. In the contemporary world, constitutionalism is practiced by not only democratic countries but also authoritarian states for the sake of economic development. This chapter addresses the following questions: First, why would authoritarian regimes accept the idea of constitutionalism and legality? Second, what makes authoritarian constitutionalismfunctional and stable and why has it worked in some countries but not others? Third, whether and under what conditions would authoritarian constitutionalism transit towards a more liberal and democratic system down the road? This chapter examines these topics in the context of selected Asian countries and provides literature review and research guidelines for readers of the Oxford Handbook of Constitutional Law in Asia.
