📰 Why is the Constitution (131st Amendment) Bill, 2026 in News?

📚 Background

The issue of women's representation in legislative bodies has remained a subject of constitutional and political debate for several decades. In order to improve women's participation in law-making institutions, Parliament enacted the Constitution (106th Amendment) Act, 2023.

The amendment provides for reservation of one-third of the total seats for women. However, the reservation does not come into effect immediately. Its implementation has been made conditional upon the completion of the next Census and the subsequent delimitation exercise.

👩 Women's Reservation under the Constitution (106th Amendment) Act, 2023

The Constitution (106th Amendment) Act, 2023 provides 33% reservation for women in elected legislative bodies.

The reservation seeks to improve women's participation in governance and strengthen representative democracy. However, the reservation will become operational only after fresh delimitation based on the next Census.

🗺️ Link Between the Bill and Delimitation

The Constitution (131st Amendment) Bill, 2026 has been widely discussed in the context of the upcoming delimitation exercise.

Delimitation refers to the process of redrawing the boundaries of Parliamentary and Legislative Assembly constituencies based on changes in population. It also determines the allocation and redistribution of seats among different States.

Since women's reservation is proposed to be implemented only after delimitation, the Bill has acquired considerable constitutional significance.
