Shashi Tharoor questions Govt's delimitation push: 'No established democracy does this'
Debate continued over the government's push to expand the Lok Sabha from its current strength of 543 to 850 seats through a delimitation exercise, months after the Constitution (131st Amendment) Bill, 2026 — which would have enabled this expansion — was defeated in the Lok Sabha on 17 April 2026, falling 54 votes short of the two-thirds majority required for a constitutional amendment (298 in favour, 230 against, against a threshold of 352).
The defeat of the 131st Amendment Bill also led to the withdrawal of dependent legislation, including the Delimitation Bill, 2026 and the Union Territories Laws (Amendment) Bill, 2026, which had been contingent on the constitutional amendment passing.
Concerns have been raised regarding whether the government's mathematical justification for expansion — that Lok Sabha strength has stayed frozen since 1971 while the population has more than doubled — adequately accounts for the institutional consequences of a much larger legislature, including how effectively such a chamber could function as a forum for scrutiny, debate, and individual member participation.
Separately, the proposed expansion is linked to the operationalisation of the 33% women's reservation in the Lok Sabha and state assemblies, which under the enabling law can only take effect after a fresh delimitation following a census conducted after the amendment's commencement.
Article 82 and the Delimitation Mechanism
Article 82 of the Constitution requires Parliament to enact a Delimitation Act after every Census, under which the allocation of Lok Sabha seats among the states, and the division of each state into territorial constituencies, is readjusted. Delimitation is thus constitutionally meant to be a recurring, census-linked exercise ensuring that representation keeps pace with population change.
Key Details
- Delimitation is carried out by a Delimitation Commission constituted under a Delimitation Act (most recently the Delimitation Act, 2002), typically comprising a retired or sitting Supreme Court judge as chairperson, the Chief Election Commissioner (or an Election Commissioner nominated by the CEC), and the concerned State Election Commissioners, with Members of Parliament and state legislators from the affected states as non-voting associate members.
- Delimitation covers two distinct functions: allocating the total number of seats among states (inter-state allocation) and redrawing individual constituency boundaries within a state (intra-state boundaries).
- The last Delimitation Commission (2002–2008) redrew constituency boundaries using 2001 Census data but did not alter the total number of seats allotted to each state, which has remained based on the 1971 Census since 1976.
The 850-seat expansion proposal would be the first change to the inter-state allocation of Lok Sabha seats since 1971, which is precisely why it required a constitutional amendment (the 131st Amendment Bill) rather than an ordinary Delimitation Act.
The Seat Freeze — 42nd, 84th, and 87th Amendments
Since 1976, the total number of Lok Sabha seats and their allocation among states has been frozen, a deliberate policy shift away from the plain reading of Article 82 in order to avoid penalising states that achieved faster demographic transition through effective population control.
Key Details
- The 42nd Amendment Act, 1976 froze the total number of Lok Sabha seats and their state-wise allocation on the basis of the 1971 Census, originally until the first census after 2000, so that states with lower population growth (mainly in the south) were not disadvantaged in Parliament relative to states with higher population growth.
- The 84th Amendment Act, 2001 extended this freeze on state-wise allocation and total seats until the first census taken after 2026.
- The 87th Amendment Act, 2003 permitted intra-state constituency boundaries to be redrawn using the 2001 Census (rather than 1971), but explicitly without changing the total number of seats allotted to each state — allowing constituency boundaries to be updated for population shifts within a state while keeping the freeze on inter-state seat shares intact. (This is distinct from the 91st Amendment Act, 2003, which instead capped the size of the Council of Ministers and tightened the anti-defection law — the two are sometimes confused because they were enacted in the same year.)
The 850-seat proposal required amending the Constitution again because both the 42nd and 84th Amendments' freeze provisions would otherwise keep total Lok Sabha strength tied to the 1971 Census until the first census after 2026 — a freeze the defeated 131st Amendment Bill sought to lift early by linking delimitation to the 2011 Census instead.
Degressive Representation and the Federal Balance Concern
Degressive representation is the principle, used in several federations and supranational legislatures, under which more populous units are given proportionally fewer seats per capita than less populous ones, so that smaller or slower-growing units are not swamped in a purely population-proportional system.
Key Details
- India's current freeze (1971 Census-based allocation) already functions as a form of degressive representation in practice: southern states that reduced population growth faster than northern states retain a Lok Sabha seat share larger than their current population share would justify under a strict per-capita formula.
- If delimitation were based on a more recent census without a corresponding degressive adjustment, seat shares would shift toward the more populous northern and eastern states, reducing the relative representation of southern and some other states — the central institutional objection raised against an early, uncapped population-based reallocation.
- Comparable degressive-representation models exist internationally, such as the European Parliament's allocation among member states, which is often cited in this debate as a possible template for balancing population-based representation with protection for smaller units.
The institutional objection to the 850-seat proposal centres on this federal-balance concern — that reallocating seats strictly by current population, without a degressive safeguard, could shift political weight away from states that met national population-stabilisation goals.
Women's Reservation and the Census-Delimitation Trigger
The Constitution (106th Amendment) Act, 2023 — the Nari Shakti Vandan Adhiniyam — inserted Articles 330A and 332A to reserve one-third of seats for women in the Lok Sabha and state legislative assemblies, but made its commencement conditional on a specific sequence: a census must first be conducted after the Act's commencement, and delimitation must then be carried out on that census before the women's quota can take effect.
Key Details
- The reserved seats are to rotate among constituencies after each delimitation exercise, and the reservation is initially valid for 15 years from commencement, extendable by Parliament.
- Because the reservation's activation is legally tied to a post-2023 census followed by delimitation, delays or defeats in the delimitation process (such as the 131st Amendment Bill's failure) directly delay when women's reservation can take effect.
- The government's stated goal linked to this timeline is implementing the women's quota from the 2029 general elections, which was part of the rationale offered for seeking to advance delimitation ahead of the standard post-2026-census schedule.
The stalled delimitation-expansion push therefore also affects the timeline for operationalising the women's reservation law, making the debate consequential for two separate constitutional commitments simultaneously.
- Current Lok Sabha strength: 543 seats, based on the 1971 Census allocation frozen since the 42nd Amendment (1976).
- Constitution (131st Amendment) Bill, 2026 proposed expanding the Lok Sabha to 850 seats (815 from states, 35 from Union Territories), linking delimitation to the 2011 Census.
- The Bill was defeated in the Lok Sabha on 17 April 2026: 298 votes in favour, 230 against, out of 528 members present — 54 votes short of the 352 needed for the required two-thirds special majority under Article 368.
- Following the defeat, the dependent Delimitation Bill, 2026 and Union Territories Laws (Amendment) Bill, 2026 were withdrawn.
- 84th Amendment Act (2001): extends the Lok Sabha seat freeze until the first census after 2026; 87th Amendment Act (2003): allows intra-state constituency redrawing on 2001 Census data without altering total state-wise seat shares.
- Women's reservation under the 106th Amendment Act, 2023 is contingent on a post-2023 census followed by delimitation; the government's associated target is implementation from the 2029 general elections.
