Residuary Powers (Article 248)

Residuary powers in the Indian constitutional scheme denote the legislative competence over subjects that the framers neither enumerated in the Union List, the State List, nor the Concurrent List of the Seventh Schedule. Article 248 of the Constitution of India assigns this competence exclusively to Parliament, declaring that Parliament has exclusive power to make any law with respect to any matter not enumerated in the Concurrent List or State List, and that such power includes the power of making any law imposing a tax not mentioned in either of those lists. This provision must be read alongside Entry 97 of the Union List in the Seventh Schedule, which functions as the substantive repository of residuary subjects, including any tax not mentioned in List II or List III. The architecture deliberately departs from the United States and Australian models, where residuary powers rest with the states.

The mechanics of Article 248 operate as a constitutional default rule. When a legislative subject arises that no entry in the three lists squarely covers—often because it did not exist or was not contemplated in 1949—the courts must first attempt to locate it within an existing entry through liberal interpretation, since entries are read in their widest amplitude. Only when this exercise fails does the matter fall to the residuary field, and competence vests automatically in the Union Parliament. The Supreme Court has insisted that recourse to the residuary power is a last resort. In Union of India v. H.S. Dhillon (1971), the Court upheld the Wealth Tax Act's levy on agricultural land by reference to the residuary power, holding that if a tax is not traceable to any entry in List II it falls within Parliament's competence under Entry 97 and Article 248.

A distinctive feature of the Indian residuary scheme is that it extends expressly to taxation. The framers, recognising the open-ended nature of fiscal innovation, ensured that any new tax not assigned to the States by List II accrues to the Centre. This was central to the gift-tax and expenditure-tax litigation of the 1960s and 1970s, and underpinned the constitutional basis for service tax before the Forty-Sixth and later the One Hundred and First Amendment (the Goods and Services Tax) reorganised indirect taxation. The pith and substance doctrine governs how courts characterise a contested law, and the residuary power is invoked only after that characterisation excludes the enumerated lists.

Contemporary illustrations make the doctrine concrete. The levy of service tax, introduced by the Union Government through the Finance Act, 1994, was sustained on the residuary power because services as such found no entry in List II; the Supreme Court affirmed this reasoning in cases such as All India Federation of Tax Practitioners v. Union of India (2007). Regulation of cyberspace and information technology, addressed by Parliament through the Information Technology Act, 2000, similarly drew strength from the residuary field, as did emergent subjects such as data governance debated by the Ministry of Electronics and Information Technology in New Delhi through the 2020s. Each instance reflects Parliament filling a gap the 1949 framers could not foresee.

Residuary powers must be distinguished from adjacent federal concepts. They differ from Article 246 read with the Seventh Schedule, which distributes enumerated subjects, because Article 248 governs only the unenumerated remainder. They differ from Article 249, under which the Rajya Sabha may by a two-thirds resolution authorise Parliament to legislate temporarily on a State List subject in the national interest. They differ from Article 252, where two or more States request Parliament to legislate for them, and from Article 254's repugnancy rule resolving conflicts within the Concurrent List. The residuary power is not a mechanism for encroachment on State subjects; it operates only where no list applies at all.

Controversy surrounds the federal asymmetry the provision embodies. Critics, including several State governments and scholars of cooperative federalism, argue that vesting residuary powers in the Centre amplifies the Union's already dominant position—reinforced by a longer Union List and Article 248's tilt. The Sarkaria Commission (1988) examined the matter and recommended that residuary subjects other than taxation could be placed in the Concurrent List, while taxation residue should remain with the Union; the recommendation was not implemented. Defenders note that the framers, mindful of Partition and centrifugal pressures, consciously chose a strong centre, and that the Supreme Court's last-resort doctrine restrains overreach. The line between a strained reading of an existing entry and genuine recourse to Article 248 continues to generate litigation.

For the working practitioner—whether a desk officer drafting legislation, a Union Public Service Commission aspirant mastering GS Paper II, or a policy analyst assessing centre-state legislative relations—Article 248 is indispensable to understanding India's quasi-federal design. It explains why novel fiscal and regulatory subjects gravitate to New Delhi, why the Supreme Court's interpretive method matters in characterising new laws, and why proposals for federal rebalancing repeatedly target the residuary clause. Mastery of the provision requires holding together the text of Article 248, Entry 97, the pith-and-substance and last-resort doctrines, and the contrast with Articles 249 to 254 that complete the constitutional scheme of legislative relations.
