All polities around the world—whether they are federal or unitary—are by default de facto asymmetric as they embody differential political units with varying size, resource endowments, demography, culture, language, nationality, and so on. Yet, not all polities envision de jure asymmetric institutional arrangements. This is plausible given that asymmetric federalism, as a normative idea and as a de jure asymmetric institutional arrangement, supports the recognition and institutional accommodation of territorially mobilised groups by envisioning ‘self-rule’ for them within the framework of ‘shared-rule’.
Driven by the majoritarian impulse to assimilate difference and establish a homogenous nation-state, integrationists are not favourable to this as they contend that asymmetric federalism reifies identities and leverages centrifugal tendencies in the long run. The cases of the former Yugoslavia and USSR are cited as exemplars to reinforce integrationists’ argument that asymmetric federalism constitutes the building block of centrifugal force which eventually led to secessionism and state break-up. On the contrary, accommodationists, who advocates asymmetric federalism, contend that it is a morally defensible idea and one of the most effective institutional arrangements to ‘hold together’ deeply divided societies like Belgium, Canada, Spain and India, and simultaneously promote peace and stability. They contend that it is not federalism per se, but the lack of democracy and genuine federalism which lies at the heart of states’ failure in eastern Europe and the USSR.
