The document provides an overview of the distribution of legislative powers between the central and state governments in India based on the country's federal structure as outlined in the constitution. It discusses the territorial jurisdiction of each, as well as the three lists that divide legislative authority - the Union List (for central government), State List (for states), and Concurrent List (for both). The central government has residual powers for any matter not addressed in the other two lists. The document also examines principles for interpreting the scope of each list, such as giving broad interpretations and determining "pith and substance" when laws overlap areas of authority.
