Chapter 1 focuses on constitution-making and constitutional reform processes. After providing a brief historical overview of the four waves of constitution-drafting in the Arab world, this chapter examines closely the post-Arab Spring constitution-making and constitutional reform processes, focusing on the following elements: The body in charge of drafting the constitution and the role played by the ruling regime (“bottom-up” vs. “top-down” processes); the degree of openness and transparency of the process; the duration of the process; the role played by political parties; the role of civil society; the role played by external actors; the influence of previous domestic constitutions and their “reactivation”; and the influence of foreign constitutional models. The chapter shows that the vast majority of these processes were characterized by major flaws and shortcomings, a fact that had a negative impact on the legitimacy and sense of ownership of these texts and, ultimately, on the transition processes as a whole. Although it should not be idealized, the process that led to the adoption of the 2014 Tunisian Constitution was to a large extent a positive exception.
