"Pluralism is the raison d’être of federalism. Federal systems are, by definition, plural: plurality of actors, plurality of powers and institutions, plurality of policies. Moreover, sharing common features, federal-type arrangements are anchored in distinct realities that invite a plurality of nuanced and contextualized analysis. This collection takes us on a journey through philosophical, theoretical, institutional and policy approaches to the multifaceted federal phenomenon, with pluralism as a method and general theme. With an impressive team of emerging and established scholars – whose work are anchored in politics, law, economics, history, philology – as guides, the volume meanders between federal structures and fundamental rights, immigration, climate change, referenda, constitutional justice, asymmetry, fiscal redistribution, political parties, local government, secession, gender equality, linguistic protection, power-sharing arrangements that both include and exclude certain groups. The result is a rich kaleidoscope of insights about the potential and pitfalls of federalism as a normative and institutional response to the challenge and promise of pluralism<i>.</i><i>" </i>(<b>J</b><b>ohanne Poirier</b>, Peter Mackell Chair in Federalism, Faculty of Law, McGill University, Canada) <p></p><p></p>
