The concept of dual sovereignty is fundamental in federal systems, where power is shared between a central authority and regional governments. Each level of government operates independently within its jurisdiction while simultaneously being subject to a constitution that delineates their respective powers. This structure allows for local governance to address regional issues effectively, fostering political decentralization. Dual sovereignty also encourages competition and innovation in policy, though it can lead to conflicts regarding authority and jurisdiction, necessitating a robust framework for conflict resolution between state and federal entities.
