Fundamentally, a constitution is the basis for the organization of the state. The state is the mechanism through which a society provides for the exercise of political, administrative, and judicial powers in order to ensure law and order, the protection of the rights of the people, and the promotion and regulation of the economy. As the notion of the sovereignty of people has superseded other beliefs about the source of ultimate authority, the constitution has come to be regarded as a contract among the people on how they would like to be governed. In most cases this is a fiction, as the people may have had no substantive role in making, or even influencing the decisions about, the new constitution. However, due to the notion of people’s sovereignty and the fundamental right of the people to participate in public affairs, there is a tendency, indeed a compulsion, to promote people’s participation in constitution-making (which is part of the inspiration for this handbook).
But the idea of a constitution as a social contract derives from another recent development—a contract not among the people to which each individual is a party, but among diverse communities in the state, often relatively new, where the bonds among the different communities are few and weak. Communities decide on the basis for their coexistence, which is then reflected in the constitution, based not only on the relations of the state to citizens but also on its relations to communities, and the relationships of the communities among themselves. In such situations, the constitution sometimes provides for “partnerships” among the communities in government and other forms of communal power sharing.
