<A>Introduction

Since the most recent reapportionment of parliamentary seats between states in 1971, India’s population has surged by nearly 1 billion, yet its political map has remained unchanged. In a hastily called special session in mid-April, the government sought to finally tackle the vexing question of delimitation through a trio of bills—but their defeat in Parliament has only sharpened, rather than settled, the debate. If anything, it underscores that the question of how India will redraw its political map—and on what terms—remains unresolved and deeply contested.

At the center of this debate is the prospect of a new delimitation exercise that would trigger a reallocation of seats across states. Such a shift could significantly alter the distribution of political power: If seats were reallocated in proportion to states’ populations, under a strict “one person, one vote” standard, faster-growing, poorer northern states would likely gain representation, while slower-growing, richer southern states would see their relative influence decline. Delimitation would also entail redrawing electoral constituencies within states, an exercise that has come under heightened scrutiny following credible allegations of gerrymandering in recent cases.

The now-defeated bills offered one possible pathway forward but left key questions unanswered. In the lead-up to the special session, the government repeatedly insisted that no state’s share of seats in the Lok Sabha (the lower house of Parliament) would decline, yet the legal text contained no such guarantee. At the same time, the legislative package sought to operationalize the Constitution (One Hundred and Sixth Amendment) Act (commonly referred to as the Women’s Reservation Bill)—passed in 2023 but not yet implemented—reserving one-third of seats for women. While the Women’s Reservation Bill is politically salient in its own right, these bills sought to operationalize it for a distinctly political purpose: The quota for women functioned as a vehicle to push through a broader reengineering of India’s electoral design.

India’s constitutional design privileges national electoral majorities through the powers vested in the Lok Sabha. Yet in practice, its political system has evolved in a more federal direction—reflecting the country’s deep linguistic, regional, and social diversity. The reorganization of states along linguistic lines, the rise of regional parties, and economic liberalization have all deepened this federal character. This evolving federal balance has been central to India’s stability as a diverse yet unified polity. With the legislative pathway now uncertain, the core question is not simply what the government proposes, but what kind of federal bargain India will ultimately strike when delimitation and the balance of representation inevitably return to the political agenda.

Historical Context

The Indian Constitution envisaged the Lok Sabha being organized according to a population-based principle. Under Article 82 of the Constitution, Lok Sabha seats must be reapportioned across, and within, states on the basis of population after each decennial census. Accordingly, delimitation followed nationwide censuses in 1951, 1961, and 1971.
