The literature on comparative constitutionalism and citizen participation in constitutional change has highlighted the importance of constitutions as political institutions for societies. This research compared citizen participation mechanisms for constitutional change (CPM-CC) in Latin America based on such specialized literature. Its central question was: which characteristics of these mechanisms’ institutional design enable their democratic implementation? Thus, the paper presented a typology that offers distinction criteria to identify when a CPM-CC potentially has democratic effects. Later, results were compared with the complete mapping of the types of CPM-CC included in the national constitutions currently in effect in eighteen Latin American countries. Finally, conclusions were presented.
