The Duterte administration (2016–22) marked the return of an authoritarian style of rule in the Philippines. It was also accompanied by an economic recovery that was better than many expected, at least until the onset of the COVID-19 pandemic. Both during and following the Duterte period, the country was buffeted by a series of internal and external shocks that called into question the state’s legal and social policy contract with its citizens. This period of “contesting the Philippines” was an intense, normative and practical struggle to shape (or reshape) some of the Philippines’ most critical institutions: the Constitution, the presidency, the Supreme Court and the rule of law, the free press, regional autonomy and independent regulatory institutions. These developments energized many domestic policy actors: technocrats, the business sector, civil society organizations, the police and the military, armed groups and religious leaders across the spectrum of Filipino politics. This volume considers some key sites of contestation between and among domestic policy actors, including the executive, during this eventful period for political and legal institutions in the Philippines.
