India’s Parliament promised, in September 2023, that one in every three seats in the Lok Sabha and every state legislative assembly would go to a woman. Three years later, that promise is a constitutional provision that is formally in force and practically dormant — and it is now the subject of a fresh Supreme Court petition, filed in the shadow of a failed constitutional amendment that tried, and failed by 54 votes, to make the promise real before the 2029 general election.

On July 17, 2026, the Supreme Court issued notice to the Union government in Yogamaya MG v. Union of India, a public interest litigation seeking implementation of the Women’s Reservation Act ahead of the 2029 Lok Sabha election without waiting for a fresh nationwide delimitation exercise. The plea, heard by a Bench of Justices B.V. Nagarathna and R. Mahadevan, argues that reservation should be operationalised using existing 2001 or 2011 Census data rather than deferred indefinitely to a census that has not yet even been scheduled. It notes that women currently hold only about 13.6% of Lok Sabha seats and roughly 14% of Rajya Sabha seats — well below the global average — a gap the 2023 law was meant to close.

This is not an abstract grievance. Only three months before the petition was filed, Parliament itself tried and failed to solve exactly this problem through legislation, and the fallout from that failure is precisely what the petitioners are now asking the Court to fix.

The Promise: What the Nari Shakti Vandan Adhiniyam Actually Does

The Constitution (One Hundred and Sixth Amendment) Act, 2023 — popularly the Nari Shakti Vandan Adhiniyam, or Women’s Reservation Act — received presidential assent on September 28, 2023. It inserts Article 330A (reserving one-third of Lok Sabha seats, including those reserved for Scheduled Castes and Scheduled Tribes, for women), Article 332A (the equivalent reservation in state legislative assemblies), and amends Article 239AA for the Delhi Assembly. Crucially, it also inserts Article 334A, the provision that has become the story’s real battleground.

The Catch Written Into Article 334A

Article 334A does not let the reservation take effect on assent, or even on notification. It ties commencement to two sequential events: the publication of population figures from “the first Census taken after the commencement of this Act,” and a delimitation exercise carried out on the basis of those figures. Only after both have happened does the one-third reservation actually apply to any election.

For three years, that made the Act’s substantive promise entirely theoretical, since no census had been conducted after 2023 and none was scheduled with a fixed date. The government did eventually notify the Act’s commencement — but only on April 16, 2026, per LiveLaw’s reporting, meaning the constitutional text is now technically in force while its operative reservation mechanism remains switched off, waiting on a census-and-delimitation sequence with no committed timeline. Absent intervention, analysts had projected actual implementation could slip as far as 2034 — two general elections after the law was enacted.

April 2026: A Notification, and a Bill That Failed by 54 Votes

The day after that notification, the government tried to solve the timing problem legislatively. The Constitution (131st Amendment) Bill, 2026 proposed to expand the Lok Sabha from 543 to 850 seats (815 for states, up to 35 for Union Territories) and, critically, to let Parliament delimit constituencies using the already-available 2011 Census rather than wait for a fresh headcount — which would have let the one-third women’s reservation take effect as early as the 2029 election instead of 2034.

Introduced alongside it were the companion Delimitation Bill, 2026 (which would have specified the 2011 Census as the operative basis and set up a new Delimitation Commission) and the Union Territories Laws (Amendment) Bill, 2026.

None of it survived the vote. Because it amended the Constitution, the 131st Amendment Bill needed the special majority under Article 368 — a majority of the House’s total membership and two-thirds of members present and voting. On April 17, 2026, it secured 298 votes in favour against 230 opposed, out of 528 members present and voting — 54 short of the 352 required, as LiveLaw and Drishti IAS both reported. Union Minister Kiren Rijiju withdrew the two companion bills the same day, since both were premised on the constitutional amendment passing.

Why the Bill Failed: A North-South Fault Line

The opposition to using 2011 Census data was not about women’s reservation itself, which enjoyed near-universal rhetorical support across party lines. It was about what that Census basis would do to seat shares. Members from southern and north-eastern states — which have controlled population growth more successfully since the 1970s freeze on delimitation — argued that population-linked reallocation of seats would penalise exactly the states that met national family-planning goals, permanently diluting their voice in Parliament relative to higher-fertility northern states. Several opposition MPs pressed for reservation to be delinked entirely from delimitation, rather than tied to any census basis, so that women’s seats could be carved out of existing constituencies without redrawing the map. That delinking is essentially what the new Supreme Court petition now asks the Court to compel by judicial direction, having failed in the House by four dozen votes.

The Petition Now Before the Court

Yogamaya MG v. Union of India asks the Supreme Court to read Article 334A in a way that does not require the delimitation exercise the political process could not deliver. The plea’s core argument is that nothing in the Constitution requires India to wait for a Census that may not be conducted, still less completed and translated into delimitation, before 2029 — when perfectly usable 2001 and 2011 Census figures already exist and were, in fact, the very numbers Parliament itself proposed to use in the defeated 131st Amendment Bill. If the government’s own bill treated 2011 data as good enough for delimitation, the argument runs, there is no principled reason it cannot be good enough to operationalise reservation now, by ordinary legislation or executive notification, without a constitutional amendment at all.

The Union government’s response to the July notice will need to explain why a path it was itself willing to legislate in April cannot simply be implemented administratively — a question the Bench of Justices Nagarathna and Mahadevan will now have to weigh against Article 334A’s plain text, which the government will likely argue leaves no room for anything short of a constitutional amendment or an actual post-2023 census.

This is not the first time this petitioner has pushed the Court toward gender-representation reform where the legislative or regulatory process stalled. In a separate matter, the Supreme Court in December 2025 directed that every State Bar Council reserve at least 30% of its seats, including office-bearer posts, for women, instructing the Bar Council of India to treat its existing election rules as amended in that spirit pending a formal rule change — a judicially engineered quota imposed precisely because the professional body had not moved on its own. Whether the Court is prepared to take a comparably direct approach to a constitutionally entrenched provision like Article 334A, rather than a subordinate election rule, is a different and much harder question, and one the pending notice does not resolve on its own.

What This Means in Practice

For now, nothing has changed on the ground: no delimitation exercise is underway, no census date is fixed, and the one-third reservation remains, as a practical matter, unenforceable in any election held today. What has changed is that the question of when it becomes enforceable has moved from a parliamentary vote count to a judicial docket.

For Indian legal professionals, the case is a live test of how far constitutional courts will go in supplying a timeline that the political process was constitutionally required — a two-thirds vote — but unable, to deliver. A ruling that reads urgency into Article 334A, or directs the government to use existing census data, would be a significant instance of judicial timeline-setting on a matter the Constitution itself left to Parliament’s legislative and administrative discretion. A ruling that defers to the government’s position — that only a fresh census, delimitation, or another constitutional amendment can trigger the reservation — would leave the 2029 election as the earliest realistic window only if the political process succeeds where it failed in April 2026, and 2034 as the more likely default.

For citizens, and particularly for the women’s groups and political parties that had pushed some version of this bill since it was first introduced in 1996 — 27 years before it finally became law — the case is a reminder that a constitutional amendment’s passage is not the same as its operation. Few pending pieces of Indian litigation carry stakes as directly countable: roughly a third of Lok Sabha seats, either from the 2029 election or from whichever one follows it.

Frequently Asked Questions

Is the Women’s Reservation Act actually in force right now?

Yes and no. The Constitution (106th Amendment) Act, 2023 was formally notified into force on April 16, 2026, so its text is now part of the Constitution and operative. However, the specific one-third reservation of seats it creates does not apply to any election yet, because Article 334A makes that reservation contingent on a census and delimitation exercise that have not occurred.

What was the Constitution (131st Amendment) Bill, 2026, and why did it fail?

It was a government bill that would have let Parliament base delimitation on the existing 2011 Census instead of waiting for a fresh post-2023 census, which would have allowed women’s reservation to take effect by the 2029 election. It needed a two-thirds majority of members present and voting in the Lok Sabha under Article 368, and secured 298 of the 352 votes required on April 17, 2026, falling short by 54 votes, largely due to opposition from southern and north-eastern states worried about losing relative seat share.

What is Yogamaya MG v. Union of India actually asking the Supreme Court to do?

The petition asks the Court to direct the Union government to implement the one-third women’s reservation using already-available 2001 or 2011 Census data, rather than waiting indefinitely for a fresh census and delimitation exercise under Article 334A, so the reservation can apply from the 2029 Lok Sabha election.

Could the Supreme Court order the government to implement reservation without a census?

It is legally uncertain. Article 334A’s text links reservation squarely to a post-2023 census and subsequent delimitation, and courts are generally reluctant to rewrite an express constitutional condition. The petitioners point to the government’s own April 2026 bill, which proposed using 2011 Census data, as evidence that such an approach is administratively workable; the government is expected to argue that only Parliament, through legislation or a fresh constitutional amendment, can substitute one census basis for another.

When will women’s reservation in Parliament realistically take effect?

There is no fixed date. If the pending litigation, a future bill, or an administrative notification does not change the current framework, implementation depends on the next Census after 2023 being conducted and a delimitation exercise following it — a sequence that had been informally projected to land around 2034, two general elections after the law’s enactment, absent the kind of legislative fix Parliament rejected in April 2026.

Does this affect the separate move to reserve seats for women in Bar Councils?

Not directly. The Bar Council reservation — a Supreme Court direction from December 2025 requiring State Bar Councils to reserve at least 30% of seats, including office-bearer posts, for women — rests on the Court’s own supervisory order over a professional regulatory body’s election rules, not on Article 334A or the 106th Amendment. It is relevant mainly as an example of the same broader push for institutional gender representation, brought in part by the same petitioner.
