GS-II covers Parliament and State Legislatures. It also includes the representation of the people and electoral processes.
Introduction
The proposed constitutional amendment package was defeated in April 2026. Consequently, post-Census seat redistribution remains unresolved, even as Census 2027 approaches. Therefore, delimitation is a process that involves equal representation, federal balance, and democratic legitimacy.
Scope and Process of Delimitation
The delimitation process follows a legal sequence. It involves allocating seats, revising boundaries, reserving seats, and public adjudication.
- Population basis: Published census figures form the demographic basis for revision.
- Seat allocation: Parliamentary and Assembly seats are distributed as per the applicable constitutional framework.
- Boundary drawing: Constituencies are redrawn to ensure geographical compactness and population balance.
- Reservation mapping: Scheduled Caste and Scheduled Tribe seats are located based on population concentration.
- Public process: Draft proposals are made public. They invite objections and public sittings before final orders are passed.
- Final publication: Delimitation Commission orders gain legal force upon their publication.
Constitutional and Legal Provisions
The Constitution distributes delimitation authority. This power is shared among Parliament, the President, and an independent Commission. It also limits ordinary judicial interference in this process.
- Article 81: Governs the composition and territorial representation in the Lok Sabha.
- Article 82: Requires readjustment after each census. This is done through parliamentary law.
- Article 170: Provides for the readjustment of State Legislative Assembly constituencies.
- Articles 330 and 332: Govern the reservation of seats for Scheduled Castes and Scheduled Tribes.
- Article 327: Authorises Parliament to legislate on elections and delimitation.
- Article 329(a): Bars courts from questioning the validity of delimitation laws.
- Delimitation Act, 2002: This Act governed the latest nationwide delimitation exercise.
Meghraj Kothari (1967) ruled that final delimitation orders have the force of law.
The Supreme Court ruled this. Article 329(a) protects delimitation laws and duly published orders. They cannot be challenged in ordinary courts. This rule ensures electoral certainty. Therefore, transparency before finalisation becomes very important.
Evolution
India's delimitation history shows two main patterns. It involves periodic readjustments and constitutional freezes. These freezes aim to protect federal incentives.
- 1952: The first Delimitation Commission drew the initial constituency map after independence.
- 1963: The second Commission used data from the 1961 Census.
- 1973: The third Commission used data from the 1971 Census.
- 1976: The 42nd Amendment froze the allocation of seats among states. This was done to prevent penalising states for their population control performance.
- 2001: The 84th Amendment extended this freeze. It would now last until the first census conducted after 2026.
- 2002: The 87th Amendment allowed for constituency readjustment. This used the 2001 Census data. Crucially, it did not change the Lok Sabha seat shares for each state.
- 2002–2008: The fourth Commission redrew most constituencies using 2001 Census data.
- 2023: The 106th Amendment linked women's reservation to a future delimitation. This delimitation will occur after the first census taken following the amendment's enactment.
April 2026 — Parliament rejected the proposed 131st Amendment package.
The Constitution (131st Amendment) Bill proposed increasing the Lok Sabha ceiling to 850 seats. Of these, up to 815 seats were intended for states and 35 for Union Territories. The constitutional Bill failed. Consequently, the connected Delimitation Bill and Union Territory amendment Bills became infructuous. Therefore, the overall proposal did not become law.

Issues and Challenges
The core challenges concern federal redistribution, vote equality, institutional trust, representation design, and implementation capacity.
Federal Balance
Population-based redistribution may penalise states with lower fertility.
States that achieved earlier demographic transition fear losing relative parliamentary influence to faster-growing states. Therefore, the dispute is about incentives and federal voice, not opposition to equal representation itself.
The freeze creates unequal population-to-seat ratios across states.
The continued use of 1971 population shares for inter-state allocation means an MP represents very different numbers of citizens in different states. This weakens the democratic principle of broadly equal vote value.
Representation and Design
Very large constituencies weaken voter access and legislative responsiveness.
Population growth has expanded the average electorate without increasing Lok Sabha seats. MPs must serve more citizens and manage complex urban-rural territories, which reduces constituency contact.
Women’s reservation makes timing and sequencing constitutionally consequential.
The 106th Amendment ties implementation to delimitation after a future census. Therefore, any delay in census publication or delimitation also postpones the reserved-seat framework.
Process and Capacity
Limited post-notification review increases the cost of procedural error.
Article 329(a) protects finality. Therefore, draft maps, reasons, hearings, and accessible data must be robust before publication. Public legitimacy depends on demonstrably neutral criteria.
Seat expansion requires physical and procedural redesign of Parliament.
More members affect chamber capacity, committee composition, speaking time, staffing, and digital systems. Numerical expansion without institutional reform may not improve deliberation.
Recommendations and Reforms
For a lasting solution, vote equality must be balanced with federal fairness. This requires consensus, transparent criteria, and institutional redesign.
Build a Federal Compact
Use an all-party and Inter-State Council process before legislation.
States need advance clarity on the population base, seat formula, transition, and safeguards. Negotiating the principles before appointing the Commission can reduce claims that the exercise is predetermined.
Separate democratic representation from fiscal reward for population control.
Finance Commission transfers and scheme design can reward demographic performance. This can be done without permanently freezing unequal constituency sizes. Therefore, federal reassurance should combine representation rules with fiscal safeguards.
Choose a Transparent Representation Model
Consider S.Y. Quraishi’s 543-seat boundary-only approach.
The former Chief Election Commissioner has argued that constituency boundaries can be revised. This can be done while retaining the Lok Sabha’s present strength. This approach reduces immediate inter-state redistribution. However, it does not fully resolve unequal state-wise vote value.
If seats expand, publish the formula and transition in advance.
Any enlargement should specify the population year, rounding method, state floor, and Union Territory treatment. The defeated 850-seat proposal is a historical proposal. It is not the current constitutional position. PRS Bill record
Protect Procedural Legitimacy
Require reasoned draft orders, machine-readable maps and accessible hearings.
Public data should show population deviation, geography, administrative boundaries, and reservation criteria for each proposal. The Election Commission’s delimitation portal can anchor a common disclosure framework.
Review parliamentary procedures alongside constituency size.
Stronger committees, research support, constituency offices, and structured speaking time can make a larger House functional. Representation gains should translate into better deliberation, not only more seats.

| Data point | Figure / fact |
|---|---|
| Delimitation Commissions | 1952, 1963, 1973 and 2002 |
| Current boundary basis | Largely the 2001 Census |
| Inter-state allocation basis | Frozen on 1971 population shares until the first census after 2026 |
| Lok Sabha strength | 543 elected seats |
| Key bar | Article 329(a) |
| 2026 proposal | Ceiling of 850 seats; defeated and not law |
Answer Framework
- Introduction: Use Census 2027 and the unresolved April 2026 package to frame the tension.
- Body: Explain the process and constitutional provisions before analysing federal, representational, and procedural concerns.
- Legal anchor: Use Articles 82 and 170 with Meghraj Kothari (1967).
- Conclusion: Recommend a transparent federal compact that combines vote equality, demographic fairness, and institutional capacity.
