'This Handbook offers a comprehensive exploration of the implications of the 'deliberative turn' in legal and political philosophy for the theory and practice of constitutionalism. It investigates not only how deliberation can enhance constitution-making but also, and more innovatively and importantly, how it can improve the everyday working of constitutional systems. Deliberation thereby becomes an important goal of constitutional design. The focus on deliberation also serves to close the gap that is sometimes thought to exist between constitutionalism and democracy. As the authors show, democracy and constitutional law can mutually reinforce their respective deliberative qualities, increasing the legitimacy and justification of each.'
