What system of goivernment do the regional governments tell the central government what to do?

The system of government where regional governments have the authority to direct or significantly influence the central government is known as a confederation. In a confederal system, power is primarily held by the individual states or regions, which retain a high degree of autonomy and can dictate certain actions to the central authority. This contrasts with a federal system, where power is more evenly distributed between the central government and the regional entities. Examples of confederations include the European Union and the historical Articles of Confederation in the United States.
