"despite mainly focusing on the Italian case, the book is clearly ambitious in its scope and its significance goes beyond one country. All contributors bring new evidence and offer original insights to debates on federalism, regionalism and decentralization. …one key lesson can be drawn from this collection of studies: a regional state can provide a flexible (and original) model of autonomy and territorial governance for countries that seek to accommodate cultural or socio-economic diversity without formally splitting sovereignty."Davide Vampa, Publius: The Journal of Federalism 52:1, e5`The book is … warmly recommended not just to scholars interested in Italian constitutional law, but to a global audience of federalists, regionalists and others dealing with the constitutional accommodation of diverse territories in a nation state.’ Anna Gamper, European Public Law 28, no. 2 (2022): 321–32
