Introduction
This chapter reviews the growing literature on constitutional unamendability and provides a unique analysis of unamendability in democratic constitutionalism. It looks at the democratic challenge of eternity clauses that goes beyond the old tension between constitutionalism and democracy. It also assesses unamendability in constitution-making and constitutional interpretation. This chapter reveals how eternity clauses are a far more ambivalent constitutional mechanism than hitherto understood, which has greater and more insidious potential for abuse. It offers a novel look at unamendability in democratic constitutions by placing the rise of eternity clauses in the context of other significant trends in recent constitutional practice, such as the rise of participatory constitutional change and the transnational embeddedness of constitution-making and constitutional adjudication.
