In a special session in September 2023, Parliament passed the Nari Shakti Vandan Adhiniyam — the Constitution (106th Amendment) Act — reserving one-third of seats for women in the Lok Sabha and state legislative assemblies. The bill passed with rare unanimous support. Yet as of September 2026, not a single seat has actually been reserved under it. The reason lies in one word buried in the law’s machinery: delimitation.

What the law says

The Act mandates 33 per cent reservation for women in the Lok Sabha and all state assemblies, with a sub-quota for women within the seats already reserved for Scheduled Castes and Scheduled Tribes. Reserved constituencies will rotate after each delimitation exercise, so that the same seats are not permanently earmarked. It is the most ambitious expansion of women’s political representation since the 73rd and 74th Amendments reserved seats for women in panchayats and municipalities in the early 1990s.

Once delimitation is notified, one-third of the constituencies in each state will be reserved for women, and the reserved set will rotate in the next delimitation cycle — so no constituency stays reserved forever, and every constituency can expect to be reserved in turn. Within the seats already reserved for Scheduled Castes and Scheduled Tribes, one-third will be reserved specifically for women from those communities, creating a layered quota.

The delimitation catch

The 2023 law tied implementation to a fresh delimitation based on the next census. But the 2021 Census was delayed by the pandemic and never conducted, leaving the timeline open-ended — under the original law, the quota would not have been enforceable before 2034. The Union Law Ministry notified the Act as coming into force on April 16, 2026, but officials confirmed it could not apply to the current House. To break the deadlock, the government introduced three bills in 2026 — the Constitution (131st Amendment) Bill, the Delimitation Bill and the Union Territories Laws (Amendment) Bill — aiming to complete delimitation using 2011 Census data and implement the quota before the 2029 general elections. Prime Minister Narendra Modi publicly affirmed 2029 as the deadline in April 2026.

The three 2026 bills and what each is meant to do:

• The Constitution (131st Amendment) Bill, 2026 — amends the reservation provision to delink it from the pending census
• The Delimitation Bill, 2026 — provides the legal framework for the fresh delimitation exercise
• The Union Territories Laws (Amendment) Bill, 2026 — extends the changes to assemblies in Union Territories

The southern states’ worry

Delimitation redistributes parliamentary seats by population, which alarms southern states — Tamil Nadu, Kerala, Karnataka, Andhra Pradesh and Telangana — that controlled population growth through effective family planning. A strictly population-based carve-up could shrink their relative representation in favour of high-growth northern states. The government’s answer is to expand the total Lok Sabha strength — figures around 816 seats have been discussed — rather than merely redistributing the existing 543, protecting southern states’ numbers while adding seats elsewhere.

Southern leaders have demanded explicit assurances that their states will not be punished for successful population control, turning delimitation into a wider federal debate about how representation should be shared between fast-growing and slow-growing states. The Centre’s position is that expanding the House, rather than redistributing existing seats, protects every state’s current strength.

Where things stand

The amendment bills remain under parliamentary debate. The Opposition, while backing the 2029 goal, attacked the April 2026 notification’s timing — the Congress called it “absolutely bizarre” that the original Act was enforced mid-debate on amending it. Until the bills pass and delimitation is completed, the 33 per cent promise remains a law in force but not yet in effect.

The Union Cabinet’s April 2026 decision to use 2011 Census figures as the delimitation baseline was the crucial unlock: it removed the open-ended wait for a new census, which has no announced date, and gave the delimitation exercise a demographic anchor it can proceed on immediately. The question now is purely legislative — whether the three 2026 bills can clear Parliament in time for the machinery to finish before 2029.
