India's women's reservation law and the wait for delimitation

What the law does

The Constitution (106th Amendment) Act, 2023, known by its Hindi name the Nari Shakti Vandan Adhiniyam, reserves one-third of the seats in the directly-elected Lok Sabha, the state legislative assemblies and the Delhi legislative assembly for women, according to the amendment’s provisions. The reservation applies within the seats already reserved for Scheduled Castes and Scheduled Tribes — so one-third of SC and ST seats are reserved for women from those categories. Reserved seats are to rotate after each future delimitation, and the reservation carries a 15-year sunset from the date it takes effect, subject to extension by Parliament. The Act does not cover the Rajya Sabha or the state legislative councils.

Parliament passed it with near-unanimity in a special session: the Lok Sabha cleared it on 20 September 2023 and the Rajya Sabha on 21 September 2023, with the President giving assent on 28 September 2023. It was the culmination of a debate reaching back to a first women’s reservation bill in the 1990s, versions of which repeatedly lapsed, as explained by Drishti IAS.

Why nothing has changed yet

The law is on the books but the quota is not in effect. The Act ties commencement of the reservation to a delimitation exercise carried out on the basis of the first census taken after the Act comes into force, per its own text. On 16 April 2026 the Ministry of Law and Justice notified that date as the commencement of the Act, as reported by LawBeat, but that only started the clock: with no fresh census figures yet published and no delimitation done, the one-third reservation remains inoperative.

The relevant census is the 2027 Census, whose house-listing phase began on 1 April 2026, with population enumeration scheduled for February 2027 and a reference date of 1 March 2027, according to the census schedule. A delimitation redrawing of constituency boundaries follows the publication of census data. The Down To Earth analysis characterises the earliest realistic application of the quota as the 2029 general election, and possibly later, since the sequence of census, then delimitation, then a rotation of reserved seats has not been completed and the government has notified only the enabling framework, not the quota itself.

The April 2026 attempt to move faster

In April 2026 the government moved to compress that wait. It brought a package of three bills before Parliament: the Constitution (131st Amendment) Bill, 2026, the Delimitation Bill, 2026 and the Union Territories Laws (Amendment) Bill, 2026. The design, as set out in the PRS bill track, was to let delimitation — and with it the women’s reservation — proceed on the basis of the 2011 Census, the latest published count, rather than waiting for the 2027 figures. The 131st Amendment Bill would have raised the maximum size of the Lok Sabha from 550 to 850 seats and removed the requirement that women’s reservation rest on the first census after the 2023 Act, so the quota could apply on the basis of a delimitation using the 2011 count, per the PRS bill track.

A constitution amendment requires a special majority of not less than two-thirds of members present and voting, and the 131st Amendment Bill was negatived in the Lok Sabha on 17 April 2026. As a direct consequence the Delimitation Bill, 2026 was recorded as “infructuous” on 17 April 2026, per PRS — it lapsed without being passed. With the fast-track route closed, the default position under the existing law stands: the next delimitation, and therefore the reservation, waits on the 2027 Census.

The contested part: delimitation and the North–South divide

The opposition to the fast-track package was rooted less in women’s reservation itself — which enjoys broad cross-party backing — than in the delimitation it would have triggered. Southern states argued that redrawing Lok Sabha seats on population lines would shift parliamentary weight toward faster-growing northern states and shrink the South’s relative representation, a concern set out in the Outlook explainer, which reported that the governments of Tamil Nadu, Karnataka, Kerala and Telangana opposed the exercise. The government’s stated case, as reported by Down To Earth, was that using the already-available 2011 data would let the quota apply from the 2029 general election rather than being deferred further; the government’s stated timeline, recorded alongside the 16 April 2026 notification, is to implement the reservation from the 2029 general election, per LawBeat. The two positions are therefore not “for or against women’s reservation” but a dispute over which census, on what timeline, with what consequence for federal balance — and that dispute is why the reservation remains legally live but practically pending as of 6 July 2026.

What the ministry runs in the meantime

The reservation law sits alongside the day-to-day welfare machinery that the Ministry of Women and Child Development actually operates. For 2025-26 the ministry was allocated about ₹26,890 crore, a 16% rise over the previous year’s revised estimates, distributed across its three umbrella missions, according to the PRS Demand for Grants analysis:

• Saksham Anganwadi and Poshan 2.0 (~₹21,960 crore, ~82% of the budget) — the nutrition mission delivered through roughly 14 lakh anganwadi centres, which absorbed the Integrated Child Development Services, POSHAN Abhiyaan and the adolescent-girls scheme.
• Mission Shakti (~₹3,150 crore, ~12%) — women’s safety and empowerment, under its Sambal (safety) and Samarthya (empowerment) sub-components, which subsumed Beti Bachao Beti Padhao and the maternity-benefit scheme.
• Mission Vatsalya (~₹1,500 crore, ~6%) — child protection and adoption, replacing the earlier Child Protection Services scheme.

PRS also records that the ministry has underspent its allocation in successive years, attributing part of the gap to delays in state cost-sharing under centrally-sponsored schemes. These schemes — not the reservation quota — are the ministry’s live operational footprint, and they are described on the WCD ministry’s portal.

Who owns this topic (and why we’re here)

A search for “Nari Shakti Vandan Adhiniyam” or “women’s reservation India” today returns two kinds of pages: exam-prep explainers (Drishti IAS, StudyIQ, Civilsdaily and similar) written for aspirants, which are strong on the constitutional mechanics but frozen at the 2023 passage and rarely track the 2026 gazette notification or the failed fast-track bills; and primary or encyclopaedic sources (PRS bill tracks, PIB releases, Wikipedia) that are accurate but scattered across the reservation law, the 2027 census and the delimitation debate as separate threads. What is missing is a single maintained state-of-play that holds all three together with provenance intact — the law, the reason it is still dormant, the April 2026 attempt to accelerate it, and the child-welfare schemes the ministry runs alongside — anchored to a structured Ministry of Women and Child Development dossier. That is the gap this brief fills.
