Detail

1. What delimitation is and why it is needed

  • Delimitation means two jobs:
  • deciding how many seats each state gets in the Lok Sabha and in its assembly;
  • drawing the boundaries of each constituency (the area that elects one member).

  • Goal: equal value of each vote. Each seat should have roughly the same population.

  • Without delimitation, one MP might represent 5 lakh people and another 25 lakh.
  • A vote in the bigger seat would then count for one-fifth of a vote in the smaller seat.

  • This is the idea of "one person, one vote, one value": every citizen's vote should carry equal weight.

  • Delimitation also decides which seats are reserved for Scheduled Castes (SC) and Scheduled Tribes (ST). Seats are reserved where their share of the population is highest (NCERT Class 11, Ch 3).

2. Constitutional basis

Provision What it says
Art. 81 Sets the size of the Lok Sabha. The current maximum is 550 members: up to 530 from states and up to 20 from Union Territories [3]. Each state gets seats in proportion to its population, as far as practicable.
Art. 82 After each census, seats and boundaries must be readjusted by an authority that Parliament sets up by law.
Art. 170 Does the same for state Legislative Assemblies (minimum 60, maximum 500 members).
Arts. 330 and 332 Reserve seats for SCs and STs in the Lok Sabha and the assemblies, in proportion to their population.
Art. 329(a) Courts cannot question laws on delimitation or on the allotment of seats.

3. The Delimitation Commission

  • Delimitation Commission: an independent body that Parliament creates by law to redraw seats. It works separately from the government of the day.
  • Four commissions so far, each under its own Delimitation Act:
Delimitation Act Census used Note
1952 1951 Before the first full redrawing
1963 1961 —
1973 1971 Last change in each state's number of seats
2002 2001 Chaired by Justice Kuldip Singh; orders in force from 2008
  • Why no commission between 1973 and 2002? Because of the freeze explained in Section 4 below (this is the iest107 question).
  • Composition under the Delimitation Act, 2002:
  • Chairperson: a retired Supreme Court judge;
  • the Chief Election Commissioner (CEC), or an Election Commissioner whom the CEC nominates;
  • the State Election Commissioner of the state concerned;
  • associate members: 5 MPs and 5 MLAs from each state. They give advice but cannot vote.

  • Procedure (in order): 1. The commission prepares draft proposals. 2. The drafts are published in the Gazette of India and in local newspapers. 3. The public sends objections and suggestions, and public sittings (hearings) are held in the state. 4. The final order is published in the Gazette. 5. The order is placed before the Lok Sabha or the assembly, but they cannot change it.

  • Legal force:

  • Its orders have the force of law.
  • Art. 329(a) shields them from court challenge. In Meghraj Kothari v. Delimitation Commission (1967), the Supreme Court held that once an order is published, courts cannot question it.
  • A 2024 Supreme Court ruling held that courts can review an order that is manifestly arbitrary (plainly unreasonable) or against constitutional values.

  • Gerrymandering means drawing constituency boundaries to help one party or group, for example by splitting a community's voters across many seats. India prevents it by giving the job to an independent commission, not to the ruling party.

4. The freeze on delimitation

  • Freeze on delimitation: a constitutional rule that stops the number of seats per state from changing, even after a new census.
  • Why: states that controlled their population, mostly in the south, should not lose seats to states whose population grew faster. Otherwise success in family planning would be punished.
Amendment What it did
42nd Amendment, 1976 Froze each state's number of Lok Sabha and assembly seats at the 1971 census level until 2000.
84th Amendment, 2001 Extended the freeze until the first census after 2026. Allowed boundaries and SC/ST reserved seats to be redrawn inside each state, based on the 1991 census.
87th Amendment, 2003 Changed the basis of that redrawing to the 2001 census.
  • Results:
  • The Lok Sabha has had 543 elected seats since 1976.
  • The 2002 commission (Kuldip Singh) could only redraw boundaries within states. It could not move seats between states.
  • So constituency sizes are now very unequal across states, because 1971-based seat shares no longer match today's population.

5. Special cases

  • North-east deferral (2008): delimitation in Assam, Arunachal Pradesh, Manipur and Nagaland was put off because of security concerns and court cases.
  • Assam (2023):
  • The Election Commission of India (ECI) itself did the delimitation under Section 8A of the Representation of the People Act, 1950. This section lets the ECI delimit states where it was deferred [7].
  • It published the final order on 11 August 2023, using the 2001 census [7].
  • Seats stayed the same: 126 assembly seats and 14 Lok Sabha seats [7].
  • It received 1,222 representations (objections and suggestions) and held three days of public hearings in Guwahati in July 2023 [7].

  • Jammu & Kashmir (2020-22):

  • The J&K Delimitation Commission was chaired by Justice Ranjana Prakash Desai and worked under the J&K Reorganisation Act, 2019.
  • It set 90 assembly seats: 43 in Jammu and 47 in Kashmir.
  • It created ST-reserved seats in J&K for the first time.

6. The coming decision: Census 2027

  • Census 2027 will be the first census after 2026. So it is the census that will end the freeze.
  • The government notified its plan to hold the census in the Gazette on 16 June 2025 [6].
  • Reference date (the moment the count describes): 00:00 hours, 1 March 2027 [6].
  • For Ladakh and the snow-bound areas of J&K, Uttarakhand and Himachal Pradesh, it is 00:00 hours, 1 October 2026 [6].
  • It will be held in two phases and will also count castes [6].

  • The problem: a purely population-based reallocation would move seats from the south to the north.

  • Projections under the 2026 Bills (2011 census, House size kept the same): Tamil Nadu 39 → 32; Uttar Pradesh 80 → 89; Bihar 40 → 46 [2].
  • UP and Bihar together would rise to 25% of all seats, up from 22%. Kerala and Tamil Nadu would be the main losers [5].

  • Options:

  • Enlarge the House so that no state loses seats. The new Lok Sabha chamber can seat 888.
  • Extend the freeze again. In March 2025, Tamil Nadu led a Joint Action Committee of states demanding this.
  • Use a weighted formula, mixing population with other factors.

7. The Delimitation Bills of 2026 (failed attempt)

  • On 16 April 2026, three Bills were introduced in the Lok Sabha together [2][3]:
  • the Constitution (131st Amendment) Bill, 2026;
  • the Delimitation Bill, 2026;
  • the Union Territories Laws (Amendment) Bill, 2026.

  • What the 131st Amendment Bill proposed [3]:

  • Remove the freeze. Each state would get seats in proportion to its population, and seats within a state would have equal population.
  • Remove the duty to delimit after every census. Parliament would decide by law which census to use, as long as its figures had been published.
  • Raise the maximum size of the Lok Sabha from 550 to 850: up to 815 from states and up to 35 from UTs.
  • Delink women's reservation from "the first census after 2023". Women's reservation could then begin through this delimitation.

  • Delimitation Bill, 2026 [2]:

  • Use the latest census whose figures were published when the commission is set up. In practice this meant the 2011 census.
  • The commission would be: a sitting or retired Supreme Court judge as chairperson, the CEC or an EC the CEC nominates, and the State Election Commissioner.

  • Government's case: under a 50% increase in House size, the Lok Sabha would grow from 543 to 816, and the southern states' seats from 129 to 195. Their share would stay at about 24% [8].

  • Outcome:
  • The 131st Amendment Bill was negatived (voted down) in the Lok Sabha on 17 April 2026 [4].
  • The other two Bills became infructuous (pointless), because they depended on it [2][4].

  • Why it was hard to pass:

  • Amending the Constitution under Art. 368(2) needs a special majority in each House. This means a majority of the House's total membership and two-thirds of members present and voting.
  • A change to the "representation of States in Parliament" also needs ratification by at least half of the state legislatures.

  • Where things stand now: the 84th Amendment's freeze still applies. It ends once the figures of Census 2027 are published. Parliament must then pass a new Delimitation Act or amend the Constitution again.

8. Links to other topics

  • Women's reservation (106th Amendment, 2023):
  • It reserves one-third of seats in the Lok Sabha and state assemblies for women.
  • It begins only after a delimitation based on the first census after 2023 [3].
  • Since the 2026 Bill failed, this link still holds. So women's reservation now depends on delimitation after Census 2027.

  • Finance Commission: a similar debate exists in fiscal federalism (how money is shared between the Centre and states). Using population as a weight for sharing central taxes can likewise "punish" states that controlled population.

Prelims Hooks

  • Art. 82 = readjustment after each census by an authority that Parliament provides. Art. 170 = the same for assemblies. Art. 329(a) = courts cannot question delimitation laws.
  • 42nd Amendment (1976) froze seats on the 1971 census till 2000. 84th (2001) extended the freeze till the first census after 2026. 87th (2003) moved boundary redrawing to the 2001 census.
  • Four Delimitation Commissions: 1952, 1963, 1973, 2002. None between 1973 and 2002 because of the freeze.
  • Kuldip Singh = 2002 Delimitation Commission. Ranjana Prakash Desai = J&K Delimitation Commission (90 seats: 43 Jammu, 47 Kashmir).
  • Meghraj Kothari (1967): delimitation orders cannot be challenged in court once published.
  • Section 8A, RPA 1950: the ECI delimits deferred states. Assam's final order (11 August 2023) kept 126 assembly seats and 14 Lok Sabha seats, using the 2001 census [7].
  • Census 2027 reference date: 1 March 2027; 1 October 2026 for Ladakh and snow-bound areas [6].
  • Trap: the Constitution (131st Amendment) Bill, 2026 (maximum Lok Sabha size 850) was negatived on 17 April 2026. It is not law. The current maximum is still 550 [3][4].
  • Trap: associate members (MPs and MLAs) of the Delimitation Commission cannot vote.

Mains Points

  • Equality vs. federal fairness:
  • "One person, one vote, one value" calls for seats by population.
  • Federal fairness says states that met national population goals should not lose political voice.
  • A middle path: enlarge the House so that no state loses seats [8], or use weighted formulas.

  • Risks of a bigger House:

  • An 850-member Lok Sabha [3] would still shift relative power northward (UP and Bihar from 22% to 25% of seats) [5].
  • It may also make debate harder and give each MP less time to speak.
  • The Rajya Sabha or decentralisation could be used to balance this.

  • Lessons from the 2026 failure [4]:

  • Delimitation changes need wide consensus. The special majority and state ratification under Art. 368 protect against change by one region alone.
  • A road map agreed with all parties, such as an inter-state dialogue, is a reform option.

  • Delinking women's reservation:

  • Under the 106th Amendment, women's reservation is held up until the delimitation dispute is settled.
  • Separating the two would let women's reservation begin sooner.
