In Chapter 5 the definition of political institutions drives us to a discussion of the main ‘institutes’ that constitute them. Individual and atomistic political norms and rules are so many over space and time that a detailed discussion is impossible. While norms/rules identify micro political institutions, with the term ‘political institute’ I identify those clusters of norms-rules that preside over the solution to a functional political problem, namely: norms and rules of selection, responsibility, inclusion, representation, decision, competence, accountability, devolution and redress. In my view, these nine institutes cover and exhaust the field of political normativity. Each of them is discussed analytically and historically in the chapter.
