Panel recommends targeted splitting of seats for next delimitation exercise

UPSC Prelims + Mains Study Note

1. At a Glance

• Delimitation is the process of redrawing boundaries of Lok Sabha and State Legislative Assembly constituencies; it is constitutionally mandated after every census under Articles 81, 82, and 170. [2]
• The Economic Advisory Council to the Prime Minister (EAC-PM) released a working paper in June 2026 proposing a multi-factor, "targeted" approach to splitting constituencies rather than a uniform population-based formula. [1]
• The proposal would expand Lok Sabha from 543 to 824 seats, preserving the current proportional share of seats for all large states — directly addressing the North-South demographic imbalance debate. [1]
• Critical for UPSC because it intersects federalism, representation, census-based apportionment, women's reservation, and constitutional amendment — touching GS-II and GS-I simultaneously. [2]

2. Why in the News

• April 16, 2026: Three delimitation-related Bills introduced in Lok Sabha — (i) Constitution (131st Amendment) Bill, 2026, (ii) Union Territories Laws (Amendment) Bill, 2026, and (iii) Delimitation Bill, 2026 — but failed to pass. [2]
• June 11, 2026: EAC-PM released a new working paper recommending "targeted splitting" of seats with multi-factor criteria as an alternative approach to the stalled legislation. [4]
• The paper is significant because it aligns broadly with the government's April proposal but provides an independent analytical justification with a dataset drawn from Lok Sabha elections 2009–2024. [4]

3. Background & Evolution

• 1950–51: First Delimitation Commission constituted under the Delimitation Commission Act, 1952.
• 1971 Census: Seats allocated to states in Lok Sabha were fixed based on 1971 population data.
• 42nd Constitutional Amendment, 1976: Froze the total number of LS seats per state based on the 1971 census to prevent penalising states with better population control. [3]
• 84th Constitutional Amendment, 2001: Extended the freeze until the first census after 2026 (i.e., the current freeze expires after Census 2031 at the latest, but legislation could trigger earlier action). [3]
• 2002: Last major delimitation exercise for LS constituencies (boundaries redrawn, not seat counts changed), conducted by the Delimitation Commission of India under a retired Supreme Court judge.
• Women's Reservation Act, 2023 (106th Amendment): Linked women's reservation (33%) in LS and state assemblies to a fresh delimitation — making the timing of delimitation politically and legally urgent. [3]
• 2026 (April): Government introduces three Bills to enable delimitation based on 2011 Census (not 2031), expanding LS to up to 850 seats (815 for states + 35 for UTs) — Bills lapse after Rajya Sabha opposition. [2]

4. Core Static Facts

5. Multi-Dimensional Analysis

Legal / Constitutional

• Articles 81 & 82 mandate post-census reapportionment; the 84th CA froze this until after the first census post-2026, making 2026 the trigger point for constitutional action. [3]
• Constitution (131st Amendment) Bill, 2026 would: (a) raise LS maximum to 850; (b) remove the constitutional mandate for post-every-census reapportionment, giving Parliament discretion on which census to use. [2]
• Using the 2011 Census instead of waiting for 2031 Census results is contested — critics argue it perpetuates older demographic data while sidestepping a newer count. [3]

Social / Federal

• Southern states (Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana) fear losing proportional representation if seats are allocated purely on population, since they controlled population growth better than northern states. [4]
• EAC-PM's model explicitly maintains current proportional share for large states — this is its key political selling point, addressing southern states' anxieties. [4]
• SC/ST reservation for constituencies must be recalibrated with any fresh delimitation under Articles 330 and 332; new seats will require fresh reservation determination. [2]
• A new working paper finding: persistent gap in women's turnout in urban areas even after constituency splits — flagged as a governance concern. [4]

Political / Governance

• The April 2026 Bills failed to pass Parliament — indicating opposition from regional parties, especially from the South, fearful of reduced political leverage. [2]
• The Women's Reservation Act, 2023 is effectively dormant until delimitation is completed — creating political pressure to expedite. [2]
• Three-way splits are concentrated in UP (17), Maharashtra (12), Bihar (10), West Bengal (10) — all high-population northern states — further intensifying North-South optics. [1]

Administrative

• A Delimitation Commission must be constituted afresh by Parliament via statute; orders of the Commission are not challengeable in any court (Section 10, Delimitation Act, 2002).
• The last operational Commission (2002) took nearly two years to complete its work; the process is quasi-judicial with public hearings.
• EAC-PM is an advisory body, not a statutory commission; its working paper carries persuasive but not binding weight. [1]

Historical

• India has had four Delimitation Commissions: 1952, 1963, 1973, 2002.
• The 42nd Amendment freeze was a political decision linked to Emergency-era priorities and the need to incentivise family planning without punishing compliant states. [3]

6. Recent Developments (Last 12–18 Months)

• April 16, 2026: Three delimitation Bills introduced in Lok Sabha by the Union Government; failed to pass due to parliamentary opposition. [2]
• April 2026: Constitution (131st Amendment) Bill, 2026 proposes LS maximum of 850 seats (815 states + 35 UTs). [2]
• June 11, 2026: EAC-PM working paper released recommending 824-seat model with multi-factor, targeted splitting; dataset: LS elections 2009–2024. [4]
• June 2026: EAC-PM paper finds that 22 of the 59 two-way splits are concentrated in Kerala and Tamil Nadu under the proposed model. [1]
• Women's reservation implementation continues to be held up pending delimitation (Women's Reservation Act, 2023 enacted but not operative). [2]

8. Mains Relevance

GS Paper II — Indian Polity and Governance:

• Syllabus headings: Parliament and State Legislatures; Representation of People; Constitutional Amendments; Federalism

GS Paper I — Social Issues:

• Syllabus heading: Population and Associated Issues; Women's empowerment

Plausible Mains Question Stems:

1. "The delimitation of Lok Sabha constituencies based on population alone risks penalising states that achieved better demographic transition. Critically examine the multi-factor approach recommended by the EAC-PM and its implications for federal equity." (GS-II, 15 marks)

2. "Discuss the constitutional provisions governing delimitation in India. How does the 'seat-freeze' principle embedded in the 42nd and 84th Constitutional Amendments attempt to balance population-based representation with federal equity?" (GS-II, 10 marks)

3. "The operationalisation of women's reservation under the 106th Constitutional Amendment is contingent on delimitation. Analyse the political and administrative bottlenecks that have delayed this reform." (GS-I/GS-II, 10 marks)

10. Common Errors / Trap Areas

1. Confusing EAC-PM with Election Commission of India (ECI): EAC-PM is an advisory economic body attached to PMO; the Election Commission and a statutory Delimitation Commission actually implement delimitation. The EAC-PM paper is recommendatory only.

2. Wrong amendment for the seat-freeze: Aspirants often attribute the freeze solely to the 84th Amendment — but the 42nd Amendment (1976) first imposed it; the 84th merely extended it to post-2026.

3. Confusing 131st CA Bill (2026) seat ceiling: The government Bill proposes a maximum of 850 seats; the EAC-PM model results in 824 seats. These are different figures from different bodies.

4. Assuming delimitation = boundary changes only: Delimitation can also change the number of seats per state (reapportionment) — the current exercise proposes both boundary redraws and seat increases, unlike 2002 which only redrew boundaries.

5. Women's Reservation activation date: A common misconception is that the 106th CA (2023) immediately activated 33% reservation. It explicitly states reservation kicks in only after delimitation is carried out following the census — making it currently inoperative.
