Delimitation: Between constitutional statesmanship and political expediency

By M K Stalin (Chief minister of Tamil Nadu)
Delimitation is not a mechanical exercise in arithmetic. It must reconcile the equality of citizens with the dignity of states and preserve the delicate federal equilibrium of a diverse Union. The moment calls for deliberation, not haste. “In the legislature, promptitude of decision is oftener an evil than a benefit.” —Alexander Hamilton, TheFederalist No. 70 (1788)

A Constitution is no ordinary instrument; it is the enduring charter of a people. Its amendment must be undertaken with restraint, sobriety, and deep deliberation. If haste is undesirable even in ordinary legislation, it is wholly out of place in altering constitutional fundamentals. Measures grounded in sound policy do not fear scrutiny; it is those driven by narrow, self-serving objectives that seek refuge in speed. Statesmanship invites scrutiny; it does not evade it.

A stark illustration is the proposed consideration of the One Hundred and Thirty-first Constitution Amendment Bill, 2026, the Delimitation Bill, 2026, and the Union Territories Laws Amendment Bill, 2026, in a special Parliamentary session convened between April 16 and 18 —barely a fortnight after the conclusion of the Budget Session on April 2 with the bills circulated to MPs scarcely two days in advance. These bills raise serious concerns for democratic legitimacy and India’s federal balance.

Architecture of representation

Few constitutional processes in India are as consequential — and as insulated from scrutiny — as delimitation. It determines how citizens are represented in the Lok Sabha and state legislative assemblies, and thereby shapes the distribution of political power. Yet once completed, its outcomes are virtually immune from challenge — therein lies the rub.

The Constitution envisages delimitation as a periodic, post-Census exercise. Articles 81 and 82 prescribe a two-stage process for the Lok Sabha. First, seats are allocated among the states so that population and representation remain broadly proportional “so far as practicable”, with special protection given to smaller states. Second, each state is divided into territorial constituencies of roughly equal population. Article 170 applies the same logic to state legislative assemblies. In R C Poudyal vs Union of India (1993), Supreme Court affirmed that proportionality is a guiding principle, not a mathematical straitjacket, permitting deviations to preserve federal balance.

Parliament enacts a Delimitation Act after each Census and entrusts the exercise to an independent delimitation commission appointed by the Union govt. The Delimitation Acts of 1952, 1962, and 1972 realigned representation with population growth.

The great freezeThe total fertility rate (TFR) — the average number of children a woman is expected to bear over her lifetime — offers a clear index of demographic change, with 2.1 regarded as the replacement level (zero growth). According to the sample registration system (SRS) data for 1971, India’s TFR was 5.2, ranging from 6.1 in Uttar Pradesh to 3.9 in Tamil Nadu. By 2001, it had declined to 3.1, yet disparities persisted — from 4.5 in Uttar Pradesh to 1.8 in Kerala.

Clearly, demographic transitions across states were profoundly uneven. Some states, through sustained investments in education, public health and women’s empowerment, achieved early fertility decline; others, particularly in the populous Hindi heartland, lagged behind. Since representation translates directly into influence over constitutional change, legislation, fiscal transfers, and language policy, a strict population-based redistribution would have penalised success and rewarded inaction.

This concern is compounded by the design of the Rajya Sabha. Though conceived as a council of states, its population-based composition renders it a near-replica of the Lok Sabha. In most federations, bicameralism balances two principles: equality of citizens in the Lower House and equality of constituent units in the Upper House. The United States (two senators per state), Australia (12 per state), Brazil (three per state), and Switzerland (two per canton) follow the same logic. India’s departure from this model leaves smaller states vulnerable to marginalisation.

An alternative model is degressive proportionality, in which smaller units are guaranteed a minimum number of seats, larger ones are subject to ceilings, and representation increases with population, but not strictly in proportion. For instance, the European Parliament allocates a minimum of six seats for the smallest member-states (Malta, Luxembourg, etc) and a maximum of 96 seats for Germany. Brazil guarantees every state a minimum of eight deputies while capping São Paulo at 70 — forcing it to forfeit nearly 40 seats it would mathematically otherwise deserve. Such calibrated asymmetry preserves the voice of smaller units.

In the absence of such structural safeguards, the Forty-second Constitutional Amendment of 1976 froze inter-state Lok Sabha seat allocation at 1971 Census levels for 25 years. The Eighty-fourth Constitutional Amendment of 2001 extended this freeze by a further 25 years, until the first Census after 2026. These were not expedients, but considered acts of constitutional statesmanship, crafted to preserve federal equilibrium. While the Fourth Delimitation Commission (2002) redrew intra-state constituencies based on the 2001 Census, the relative political weights of states remained anchored to 1971. The resulting 50-year freeze has ensured that national population policy did not yield unintended — and inequitable — shifts in political power.

Continuing validity of the freeze

In 1971, Tamil Nadu and present-day Bihar had comparable populations — about 41 million–42 million — and similar Lok Sabha representation (39 and 40 seats respectively). By 2025, Tamil Nadu’s population is estimated at around 76 million, while Bihar’s has risen to nearly 123 million. On this basis, Bihar’s representation would increase to 50 seats, while Tamil Nadu’s would decline to 29.

A similar divergence is evident between Rajasthan and present-day Andhra Pradesh. In 1971, both had comparable populations and identical representation (25 seats each). Based on the 2025 population, Rajasthan’s strength would increase to 31 seats, while Andhra Pradesh’s would fall to 20.

To reward Bihar and Rajasthan with additional Lok Sabha seats while penalising Tamil Nadu and Andhra Pradesh is akin to demoting the employee who met his targets and promoting the one who failed to do so.

According to the SRS data for 2023, India’s TFR has declined to 1.9, yet significant regional disparities persist. States in the Hindi heartland — Bihar (2.8), Uttar Pradesh (2.6), Madhya Pradesh (2.4), Rajasthan (2.3), and Chhattisgarh (2.2) — continue to record higher fertility rates. Kerala, Karnataka, AP, Telangana, Punjab, and Jammu & Kashmir are now in the “1.5 TFR Club”, while Delhi (1.2), Tamil Nadu (1.3), West Bengal (1.3) and Maharashtra (1.4) have achieved even lower levels.

Two conclusions follow. First, despite a nationwide decline in fertility, the Hindi heartland states remain several decades behind much of the rest of the country in the demographic transition. Second, mere decline is insufficient; the appropriate trigger for lifting the freeze is demographic convergence, with state TFRs falling within a narrow band (say, ±10%) of the national average. Given the slow pace of convergence, Tamil Nadu calls for extending the freeze on inter-State Lok Sabha seat allocation for another 25 years — until 2051 — or until such convergence is achieved, whichever is earlier.

Perils of the proposed framework

The third proviso to Article 82 and the proviso to Article 170(2) mandate that the next delimitation be undertaken on the basis of the published figures of “the first Census taken after 2026.” This was widely understood to refer to the 2031 Census. However, the postponement of the 2021 Census altered this expectation, raising the possibility that the exercise may instead be anchored to the 2026–27 enumeration.

The proposed 131st Constitution Amendment Bill, 2026 marks a more fundamental shift. It seeks to redefine “population” as that “ascertained at such census as Parliament may by law determine,” and proposes the deletion of the provisos to Articles 82 and 170(2) referred to above. Thereby, it delinks delimitation from the latest Census and signals the discontinuance of the long-standing 1971 Census-based freeze, despite the enduring force of its rationale.

The proposal is apparently to undertake delimitation on the basis of the 2011 Census, ostensibly because the latest Census figures may not be ready in time for the 2029 general elections. Such a course would be constitutionally incongruous and normatively indefensible. Having mandated that delimitation rely on the first Census after 2026, it would be impermissible to revert to outdated 2011 data when a fresh Census enumeration is already underway.

Equally problematic is the proposal to increase the maximum strength of the Lok Sabha from 550 to 850 seats on the premise that no state should lose its existing representation. In a parliamentary democracy, power lies not in absolute numbers but in relative weight— a state’s percentage share of the total strength of the House. Thus, Kerala may retain its 20 seats in the expanded Lok Sabha, yet its relative weight would fall from 3.68%(20/543) to 2.35% (20/850). Tamil Nadu may increase from 39 to 49 seats, but its relative weight would decline from 7.18% to 5.78%. Conversely, Bihar’s Lok Sabha seats would increase from 40 to 79 and its relative weight from 7.37% to 9.32%. Uttar Pradesh’s seats would rise from 80 to 143 and its relative weight from 14.73% to 16.86%.

A more equitable approach would be to preserve each state’s existing percentage share and apply these proportions to the enlarged House. While such an assurance has been orally made by Union ministers Amit Shah and Piyush Goel, its absence from the text of the Constitution Amendment Bill renders the proposal constitutionally fragile and unacceptable.

There is also a strong institutional case against expanding the Lok Sabha. With a sanctioned strength of 550, it is already among the largest elected lower houses in the world. A House of 850 members would be unwieldy, with many MPs scarcely getting an opportunity to speak over a five-year term. It would erode meaningful debate, weaken committee effectiveness, and increase reliance on party whips and executive control. Global experience favours restraint: the US House has remained at 435 since 1929 even as the population nearly tripled; Italy reduced its Chamber of Deputies from 630 to 400; and Japan is planning reduction from 465 to 420.

Finally, the 131st Constitution Amendment Bill proposes to amend Article 334A — introduced by the 106th Amendment (2023) — which provides for one-third reservation for women but ties its implementation to a post-Census delimitation. This linkage is unnecessary and misleading. There is no constitutional barrier to implementing women’s reservation within the existing 543-seat Lok Sabha through a system of rotation. The invocation of women’s empowerment in this context is obviously a smokescreen to mask the lifting of the 1971 seat freeze and to legitimise an inequitable exercise that could unsettle the carefully maintained federal balance.

Legislative scrutiny and judicial review

Quite apart from the serious risks the proposed bills pose to democratic legitimacy and the federal compact, they also expose deeper structural infirmities in the constitutional design of delimitation that demand careful reconsideration.

Under the Delimitation Acts, including the proposed Delimitation Bill, 2026, the Delimitation Commission’s orders acquire the force of law upon publication in the Gazette. They require no approval from Parliament, State Legislatures, or even the Union Council of Ministers. Read with Article 329(a), which bars judicial interference in delimitation matters, this framework effectively places the process within a constitutional “black box”, insulated from executive, legislative, and judicial scrutiny. In Kishorchandra Chhanganlal Rathod vs Union of India (2024), the Supreme Court clarified that Article 329(a) does not confer absolute immunity. Limited judicial review remains available to correct manifest arbitrariness, provided such intervention does not disrupt the electoral timetable.

In the name of insulating delimitation from “political interference”, the present design, in fact, privileges the Union govt, which retains exclusive authority to appoint the chairperson and members of the Delimitation Commission. The result is an unaccountable body whose decisions are final, largely non-justiciable, and effectively immune from correction. Such an arrangement is difficult to justify in a foundational constitutional process affecting the distribution of political power.

Comparative international experience demonstrates that independence in delimitation need not come at the cost of accountability. In the United States, electoral boundaries are enacted through state legislation and remain fully justiciable, with courts actively intervening to curb gerrymandering and racial discrimination.

In Canada, the reports of independent federal commissions — one for each province — are tabled in Parliament, where committees examine objections raised by MPs and convey them to the commissions, with the commissions retaining final decision-making authority. Their determinations are, however, subject to judicial review. Provinces follow similar arrangements for their legislative assemblies.

In Germany and Japan, delimitation is fundamentally a legislative function guided by expert advisory commissions. Electoral boundaries acquire legal force only through parliamentary enactment, while courts retain authority to review malapportionment.

Recognising that delimitation must be independent, yet contestable and corrigible, the Justice Kurian Joseph Committee on Union–State Relations, constituted by the Government of Tamil Nadu, recommended in Part I of its Report (Feb 2026) that Articles 82, 170, and 329(a) be amended to introduce limited but meaningful institutional checks.



The committee proposed that draft delimitation orders be subject to time-bound scrutiny by Parliament and state legislatures. Drawing on Canada’s “dialogue model”, legislative committees would examine objections and convey them to the commission, which would then publish reasoned responses before finalising its orders. The final decision would remain with the commission, ensuring that legislatures have a voice, but not a veto. It further recommended stage-sensitive judicial review on constitutional and jurisdictional grounds before elections are notified, while preserving the bar once the electoral process has commenced. Pending constitutional amendments, at a minimum, the new delimitation law should incorporate these safeguards (legislative scrutiny and reasoned responses). The Tamil Nadu govt endorses these recommendations.

In the Constituent Assembly, H V Kamath had urged that no constitutional amendment be finally passed until at least six months had elapsed, so as to permit informed public debate. India’s constitutional history has, regrettably, witnessed episodes of undue haste—but none more disquieting than the 131st Constitution Amendment Bill, 2026. The Union govt would do well to withdraw it, along with the related legislation, and introduce a fresh bill in the light of these concerns. Such a bill should be placed in the public domain for at least three months, inviting wide, informed, and meaningful consultation.

In the final analysis, delimitation is not a mechanical exercise in arithmetic, but an act of constitutional statesmanship. It must reconcile the equality of citizens with the dignity of states and preserve the delicate federal equilibrium of a diverse Union. The moment calls for reflection, not expediency; deliberation, not haste. If the Constitution is to endure as a charter of trust, its amendment must be guided by principle — anchored in fairness, restraint, and fidelity to the Republic’s enduring integrity.Get real-time updates and result insights on the CBSE 12 Result 2026.
