The Concurrent List is a constitutional provision that defines the shared legislative jurisdiction between the Union Parliament and the State Legislatures in India. It is formally known as List III in the Seventh Schedule of the Constitution of India. The concept was adopted from the Australian Constitution and was created to solve the problem of balancing national uniformity with regional flexibility in a federal structure. The list was debated and included in the Constitution, which came into effect on January 26, 1950, to ensure that both the Centre and the States could legislate on subjects of common interest.
The mechanism is detailed in Article 246(2), which grants both Parliament and the State Legislatures the power to make laws on the subjects enumerated in the Concurrent List. The list originally contained 47 subjects but now has 52 entries. Key subjects include Education, Forests, Criminal Law, Marriage and Divorce, and Economic and Social Planning. The list connects directly to the other two lists in the Seventh Schedule: the Union List (List I) and the State List (List II).
A crucial provision is the rule for resolving conflicts: in case of a repugnancy between a Central law and a State law on a Concurrent List subject, the Central law prevails. This principle is enshrined in Article 254. The list has undergone significant change, notably with the 42nd Amendment Act of 1976, which transferred five subjects from the State List to the Concurrent List. These five subjects were Education, Forests, Protection of wild animals and birds, Weights and Measures, and Administration of Justice (except the Supreme Court and High Courts). This amendment expanded the Centre's legislative domain on these subjects, while the fundamental mechanism of shared power with Union supremacy in conflict remained the same.
