New constitutional horizons: towards a pluralist constitutional theory

New Constitutional Horizons is a solid and innovative contribution to a debate that has acquired a central position for decades in political and legal theory, but that nonetheless has left many unsolved issues along the evolution of constitutionalism. It is what Cormack Mac Amhlaigh calls the debate around ‘circumstances of constitutional pluralism, as establishing the conditions for theorizing contemporary legal and political practices’ beyond the monist manner of understanding state law and authority. In the background of these circumstances, there is a constitutional plurality, that is, a plurality of legal norms and political authoritative claims. The book is not a descriptive enterprise of the history of constitutional pluralist cases, but rather it focuses on the methodological ‘effects’ that constitutional pluralism has on our traditional state-based constitutional theory, enhancing its normative grasp of such plurality. In particular, the theory of constitutional pluralism ‘looks at the ways in which the constitutional tradition can be pluralized to provide a normative standard of legitimate decision-making’, within a multi-level dimension – sub-statal, statal, transnational and international.
