The Seventh Schedule is a crucial constitutional provision that defines the distribution of legislative powers between the Union and State governments in India. Its origin lies in the need to establish a clear framework for a quasi-federal system, ensuring national integration while accommodating regional diversity. The Schedule was included in the Constitution of India at its commencement in 1950 to prevent jurisdictional overlap and maintain a functional balance of power.
The mechanism of the Seventh Schedule is based on Article 246 of the Constitution, which divides subjects into three lists. List I, the Union List, originally contained 97 subjects and now has 100, on which Parliament has exclusive power to legislate, such as Defence and Foreign Affairs. List II, the State List, originally had 66 subjects and now has 61, on which State Legislatures generally have exclusive power, covering matters like Public Order and Police. List III, the Concurrent List, originally had 47 subjects and now has 52, on which both the Parliament and State Legislatures can make laws, with the Central law prevailing in case of conflict. Furthermore, Article 248 grants Parliament exclusive residuary powers to legislate on any matter not enumerated in the three lists.
The Schedule has undergone significant changes, notably through the 42nd Amendment Act, 1976, which shifted five subjects, including Education and Forests, from the State List to the Concurrent List. More recently, the 101st Amendment Act, 2016, introduced Article 246A, which makes special provisions for the Goods and Services Tax (GST), empowering both Parliament and State Legislatures to make laws with respect to GST, effectively operating outside the traditional list framework for this specific tax. This amendment significantly reshaped India's fiscal federalism.
