 While sovereignty is vested in the nation as a whole, represented in the central institutions of government, the nation has, in variable degrees, devolved power to the communities, which, in turn, exercise their right to self-government within the limits set forth in the constitution and their autonomous statutes.Each community has its own set of devolved powers; typically those communities with a stronger local nationalism have more powers; this type of devolution has been called "asymmetrical".Some scholars have referred to the resulting system as a federal system in all but name, or a "federation without federalism".
