Information: - 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 '' ) . - A constituent state is a territorial and constitutional entity forming part of a sovereign state. A constituent state holds administrative jurisdiction over a defined geographic territory and is a form of regional government. - A treaty is an agreement under international law entered into by actors in international law, namely sovereign states and international organizations. A treaty may also be known as an (international) agreement, protocol, covenant, convention, pact, or exchange of letters, among other terms. Regardless of terminology, all of these forms of agreements are, under international law, equally considered treaties and the rules are the same. - A federation (also known as a federal state) is a political entity characterized by a union of partially self-governing states or regions under a central (federal) government. In a federation, the self-governing status of the component states, as well as the division of power between them and the central government, is typically constitutionally entrenched and may not be altered by a unilateral decision of either party, the states or the federal political body. Alternatively, federation is a form of government in which sovereign power is formally divided between a central authority and a number of constituent regions so that each region retains some degree of control over its internal affairs. - Symmetric federalism refers to a federal system of government in which each constituent state to the federation possess equal powers. In a symmetric federalism no distinction is made between constituent states. This is in contrast to an asymmetric federalism, where a distinction is made between constituent states. - A confederation (also known as a confederacy or league) is a union of sovereign states, united for purposes of common action often in relation to other states. Usually created by a treaty, confederations of states tend to be established for dealing with critical issues, such as defence, foreign relations, internal trade or currency, with the general government being required to provide support for all its members. Confederalism represents a main form of inter-governmentalism, this being defined as any form of interaction between states which takes place on the basis of sovereign independence. What entity does 'asymmetric federalism' has the relation 'instance of' with?
Answer:
form of government
