Autonomy of constituent units is an important feature of

Autonomy of constituent units refers to the degree of self-governance given to regions, provinces or states within a larger country or state. This means that these units have some level of independence and authority to make their own decisions on matters that concern them. This feature is commonly associated with a confederal or federal government system, where power is shared between the central government and the constituent units. In a confederal government, the constituent units retain most of the power and authority, while in a federal government, there is a balance of power between the central government and the constituent units. A unitary government, on the other hand, is a system where all power and authority is held by the central government, with little or no autonomy given to the constituent units. A parliamentary government is a form of government where the executive branch (Prime Minister and Cabinet) is accountable to the legislative branch (Parliament). Autonomy of constituent units is not a defining feature of a parliamentary government.
