Legislating on Residuary Subjects in Federalism
Federalism divides the powers between the central government and state governments. Residuary subjects are those matters not specifically mentioned in the Constitution, and the power to legislate on these subjects is an important aspect of federalism.

Who has the power to legislate on residuary subjects?
In a federal system like India, the power to legislate on residuary subjects lies with the central government. This means that if a matter is not explicitly mentioned in the Constitution as being under the jurisdiction of the states, it falls under the authority of the central government.

Key Concepts in Federalism
1. Distribution of Powers: Federalism involves the distribution of powers between the central government and state governments. This division is outlined in the Constitution and determines which level of government has authority over specific matters.
2. Residuary Subjects: Residuary subjects are those matters not assigned to either level of government explicitly. In India, these subjects fall under the jurisdiction of the central government.
3. Importance of Residuary Powers: The central government's authority over residuary subjects ensures that there are no gaps in legislation and that all matters are effectively governed. This centralization of power helps maintain uniformity and coherence in the legal framework.
4. Balance of Power: The distribution of powers, including residuary subjects, aims to strike a balance between the central government's authority and the autonomy of state governments. This balance is essential for a functioning federal system.
In conclusion, the power to legislate on residuary subjects in federalism rests with the central government to ensure comprehensive governance and maintain the balance of power between different levels of government.
