Asymmetric federalism

Asymmetric federalism or asymmetrical federalism is found in a federation or confederation in which different constituent states possess different powers: one or more of the states has considerably more autonomy than the other substates, although they have the same constitutional status. The division of powers between substates is not symmetric. This is in contrast to symmetric federalism, where no distinction is made between constituent states. As a result, it is frequently proposed as a solution to the dissatisfactions that arise when one or two constituent units feel significantly different needs from the others, as the result of an ethnic, linguistic or cultural difference.

The difference between an asymmetric federation and federacy is indistinct; a federacy is essentially an extreme case of an asymmetric federation, either due to large differences in the level of autonomy, or the rigidity of the constitutional arrangements. An asymmetric federation, however, has to have a federal constitution, and all states in federation have the same formal status ("state"), while in a federacy independent substate has a different status ("autonomous region").

Asymmetrical federalism can be divided into two types of agreements or arrangements. The first type resolves differences in legislative powers, representation in central institutions, and rights and obligations that are set in the constitution. This type of asymmetry can be called de jure asymmetry (Brown 2). The second type reflects agreements which come out of national policy, opting out, and (depending on one’s definition of the term) bilateral and ad hoc deals with specific provinces, none of which are entrenched in the constitution. This type of asymmetry is known as de facto asymmetry. The Canadian federation uses a combination of these, which make up its asymmetrical character.

The Constitution of Canada is broadly symmetric but contains certain specific sections that apply only to certain provinces. In practice, a degree of asymmetry is created as a result of the evolution of the Canadian federal experiment, individual federal-provincial agreements, and judicial interpretation. Asymmetrical federalism has been much discussed as a formula for stability in Canada, meeting the aspirations of French-speaking Quebec for control over its cultural and social life without removing it from the national federation, where it coexists with nine largely English-speaking provinces.
