Membership to  a confederation is deemed voluntary and as a result members exercise more autonomy in decision making. this is unlike in a federation, whereby the government exercises more power over the member states. in a confederation, the authority is also answerable to the member states. in USA for example, the independence constitution established a confederation, whereby member states had more local powers.
