A constitutional knot tied in September 2023 continues to draw sharp scrutiny — and Congress MP Dr. Shashi Tharoor is now publicly aligning himself with independent legislative researchers who argue the numbers behind it don't add up. On Thursday, 30 July 2026, Tharoor confirmed on social media that he had already raised the broader constitutional objections in Parliament during the Budget Session, and that he agrees 'entirely' with the analysis put forward by PRS Legislative Research on the structural problems with tying women's reservation to delimitation.

The amendment that made women wait

The 106th Constitutional Amendment Act, 2023 — formally called the Nari Shakti Vandan Adhiniyam — was a landmark moment on paper: one-third of seats in the Lok Sabha and state assemblies reserved for women. But the fine print inserted a condition that critics have called a poison pill. The reservation kicks in only after the next national census and the delimitation exercise that follows it — a process that, given India's census delays, could push actual implementation well into the 2030s.

Tharoor pointed readers to a Budget Session speech in which he had laid out the 'broader arguments' against this constitutional design. His post on 30 July clarifies that today's conversation is specifically about the arithmetic — the numbers — rather than the constitutional philosophy, a distinction that signals a layered, ongoing debate rather than a one-time objection.

Why delimitation is the crux

Delimitation — the redrawing of constituency boundaries based on population — was last conducted in 2002 and has been frozen since. When it is eventually carried out using fresh census data, it is expected to significantly expand the seat count of high-population northern states while potentially reducing the relative weight of southern states that managed lower population growth. That demographic asymmetry has made delimitation one of the most politically charged exercises in Indian federalism.

Linking women's reservation to this exercise means the two controversies are now inseparable. Critics, including the researchers at PRS Legislative Research — a New Delhi-based non-profit known for rigorous, non-partisan legislative analysis — argue that the linkage does double duty: it delays a long-overdue gender equity measure while also deferring a politically explosive federal reckoning.

Decades of deferred promise

The demand for women's reservation in Parliament is not new. The 73rd and 74th Constitutional Amendments of 1992–93 had already mandated one-third reservation for women in panchayats and urban local bodies. A Women's Reservation Bill passed the Rajya Sabha in 2010 but lapsed without ever reaching a Lok Sabha vote. The 2023 amendment finally cleared both Houses — but the implementation trigger has effectively restarted the clock.

Tharoor's alignment with PRS on this point carries weight: he is one of Parliament's most prominent voices on constitutional matters, and his willingness to name a specific researcher and organisation — rather than issue a generic critique — signals that this debate is moving into a more technical, evidence-driven phase.

The next census and the Delimitation Commission's eventual orders will determine whether the Nari Shakti Vandan Adhiniyam becomes a historic milestone or a promise deferred yet again — and Parliament's scrutiny of that timeline is clearly not over.
