How many Delimitation Commissions have been constituted by the Government of India till December 2023 ?

The Government of India has constituted four Delimitation Commissions to date—in 1952, 1963, 1973, and 2002—under the respective Delimitation Commission Acts passed after decennial censuses. A common misconception is that there have been more, but the 2020 commission for Jammu & Kashmir and specific North-Eastern states was a limited exercise and not a fifth nationwide commission under a new Act. This question tests the core concept of Article 82 and Article 170, which govern the periodic readjustment of electoral boundaries to ensure equal representation.
