Doctrine of pith and substance



Published on 10 Sep 2025

  • The Supreme Court recently invoked the Doctrine of Pith and Substance in a case relating to service tax on lottery distributors.

  • SC held that the Centre cannot impose service tax on the distributors engaged in lottery business, as only the state governments have the power to do so.

  • The Supreme Court ruled that lotteries are a form of gambling, not a service, and therefore, the relationship between states and lottery distributors is that of a buyer and seller, not a principal-agent, making service tax inapplicable. 

  • It emphasized that the power to tax betting and gambling, including lotteries, lies exclusively with state legislatures under Entry 62 of List II.

  • This prevents Parliament from imposing service tax through its residuary powers under Entry 97 of List I.

  • The Doctrine of Pith and Substance originated in Canada and was later adopted in India through the Government of India Act, 1935.

  • It helps courts determine the true purpose of a law, even if it overlaps with another jurisdiction. 

  • It applies when a law's legislative authority is in question due to jurisdictional ambiguities. 

  • While minor overlaps are permitted, the doctrine ensures that the law’s core objective remains within the enacting legislature’s domain.
