The vast majority of contemporary constitutions describe the basic principles of the state, the structures and processes of government and the fundamental rights of citizens in a higher law that cannot be unilaterally changed by an ordinary legislative act. This higher law is usually referred to as a constitution.
International IDEA’s Constitution-Building Primers are designed to assist in-country constitution-building or constitutional-reform processes by helping citizens, political parties, civil society organisations, public officials, and members of constituent assemblies make wise constitutional choices.
