India has a federal system with a division of powers between the central government and the states. The structure of India's federal system can be summarized as follows: 1. List of Subjects: The Constitution of India divides subjects into three lists - Union List, State List, and Concurrent List. The Union List contains subjects exclusively under the central government, the State List contains subjects exclusively under the state governments, and the Concurrent List contains subjects where both the central and state governments have jurisdiction. 2. Central Government: The central government has powers over subjects such as defense, foreign affairs, currency, and communication. It also has the authority to legislate on matters listed in the Concurrent List in case of a conflict or when uniformity is required. 3. State Governments: State governments have powers over subjects such as police, public health, agriculture, and local governance. They have the authority to legislate on matters listed in the State List. However, if a state law conflicts with a central law on a Concurrent List subject, the central law prevails. 4. Residuary Powers: Any matter not explicitly mentioned in the lists falls under the residuary powers of the central government. Overall, the division of powers between the central government and the states is defined by the Constitution of India and other relevant legislation to ensure a balance between national unity and regional autonomy.
