What Happened

  • The government revealed a three-Bill package ahead of the Special Parliament Session on April 16–17, 2026: (1) Constitution (131st Amendment) Bill, 2026 — expanding Lok Sabha and amending delimitation trigger; (2) Delimitation Bill, 2026 — statutory framework for the new delimitation exercise; (3) a Bill extending women's reservation to Union Territories
  • The 131st Amendment Bill proposes a maximum Lok Sabha of 850 seats (815 from States, 35 from UTs), amending Article 81 — an increase from the current 550 constitutional ceiling (effective strength: 543)
  • The Delimitation Bill, 2026 allows the new Commission to use 2011 Census data, redraw all parliamentary and State Assembly constituencies, and allocate SC/ST reserved constituencies — with legally binding, court-proof orders
  • Article 334A is amended to remove the census-first requirement: women's reservation will take effect immediately after the new delimitation, targeting the 2029 general elections
  • The package represents the first major expansion of Lok Sabha since independence — the current 543-seat House has been in force since the 1971-based delimitation

Constitutional History of Lok Sabha Size

The present Lok Sabha strength of 543 seats was fixed following the 1972 Delimitation Commission (using 1971 Census data). The 42nd Amendment Act (1976) froze seat numbers at their 1971 levels. The 84th Amendment (2001) extended the freeze to post-2026 census, using 2001 Census for boundary adjustments (87th Amendment, 2003) but not for reallocating seats between States. The 104th Amendment (2020) abolished the 2 nominated Anglo-Indian seats, reducing the constitutional ceiling slightly. The 131st Amendment would be the first to actually expand the House since 1977.

  • 1st Delimitation Commission (1952): Used first census data; Lok Sabha had 489 seats
  • 2nd Delimitation Commission (1962): Raised Lok Sabha to 520 seats (using 1961 Census)
  • 3rd Delimitation Commission (1972): Raised to 543 seats (using 1971 Census) — still current strength
  • 42nd Amendment (1976): Froze seat numbers based on 1971 Census until 2001
  • 84th Amendment (2001): Extended freeze to first census after 2026
  • 87th Amendment (2003): Allowed boundary redrawing using 2001 Census without changing seat allocation
  • 104th Amendment (2020): Removed 2 Anglo-Indian nominated seats; current ceiling is effectively 543 elected + 2 nominated (now 0) = 543
  • 131st Amendment (proposed 2026): First actual expansion — ceiling raised to 850

Connection to this news: The 131st Amendment Bill breaks a 50-year status quo on Lok Sabha size, making it constitutionally and historically significant beyond just the women's reservation or delimitation dimensions.

Lok Sabha and State Assembly Seat Allocation — Constitutional Principles

Article 81(2) mandates that the ratio of seats to population be "so far as practicable" the same for all States. This proportionality requirement — designed for democratic fairness — is the root cause of the North-South tension in 2026 delimitation. The proposed expansion to 850 seats uses what analysts call the "grow the pie" approach: expanding the total number so that every State gains absolute seats, even as their proportional shares shift. Combined with a "proportional freeze" that prevents any State from falling below its current seat count, the Bills attempt to soften — but not eliminate — the representational shift.

  • Article 81(2)(a): Seat-to-population ratio must be same "so far as practicable" for all States
  • Article 81(2)(b): Constraints on constituency size (minimum/maximum population per seat)
  • "Grow the pie" approach: Expand total seats so no State loses in absolute terms
  • States gaining most seats (projected): Uttar Pradesh (current 80, could reach ~125-130), Bihar (current 40, could reach ~60-65), Madhya Pradesh (current 29, could reach ~40+)
  • States with minimal absolute change: Tamil Nadu (~39), Kerala (~20), Karnataka (~28) — retain current seats but drop in share

Connection to this news: Understanding Article 81(2)'s proportionality requirement explains why the Bills must expand to 850 — any reallocation within 543 seats would mean some States losing, which is politically unacceptable and constitutionally contested.

Union Territories — Representation and the Third Bill

Union Territories in India have varying forms of governance. Seven UTs exist: Delhi (Full Legislature), Puducherry (Legislature), Jammu & Kashmir (Legislature since 2019), Chandigarh (no legislature), Dadra & Nagar Haveli and Daman & Diu (no legislature), Lakshadweep (no legislature), Andaman & Nicobar Islands (no legislature), and Ladakh (no legislature — administered by LG). For Lok Sabha, UTs are represented through direct elections; the allocation was previously capped at 20 seats. The 131st Amendment raises this to 35 UT seats. The accompanying UT-specific Bill extends women's reservation to these constituencies and their governance structures.

  • UTs with Legislatures: Delhi, Puducherry, Jammu & Kashmir (total 3)
  • J&K reorganised as UT with Legislature: J&K Reorganisation Act, 2019 (effective October 31, 2019)
  • UTs without Legislatures (administered by LG/Administrator): Chandigarh, Dadra & Nagar Haveli and Daman & Diu, Lakshadweep, Andaman & Nicobar Islands, Ladakh (total 5)
  • Current Lok Sabha seats from UTs: 13 (Delhi 7, Puducherry 1, J&K 5 after reorganisation, Chandigarh 1, etc.)
  • Proposed UT Lok Sabha ceiling: 35 (from current constitutional ceiling of 20)
  • Article 239A: Parliament can create legislatures for UTs by law
  • The UT Women's Reservation Bill: Ensures 33% reservation applies to UT constituencies in Lok Sabha and UT legislatures

Connection to this news: The separate UT Bill is a necessary complement to the constitutional amendment — the 106th Amendment covered only Lok Sabha and State Assemblies, so a separate statute is needed to extend women's reservation comprehensively to UT governance structures.
