Understanding the Basis for 234 Assembly Seats

Have you ever pondered the reasons and processes that led to the establishment of 234 seats in the Tamil Nadu Assembly? This figure was determined by the Delimitation Commission, which executed a redistribution of Lok Sabha and Assembly seats following the 1961 Census.

According to Article 170 of the Constitution and Section 8(b) of the Delimitation Commission Act, 1962, the total number of seats in a State Assembly must be a multiple of the Lok Sabha seats allocated to that specific State.

At that time, among 14 States, there were 481 parliamentary seats, with Madras, the former name for Tamil Nadu, holding 41. Additionally, Jammu and Kashmir had six seats, the Naga Hills-Tuensang Area one seat, the North East Frontier Tract one seat, and the Union Territories held 18 seats, which brought the grand total to 507.

The Delimitation Commission, led by Justice J.L. Kapur and accompanied by members C.P. Sinha and K.V.K. Sundaram, noted that Article 81(1) set the upper limit for directly elected Lok Sabha members at 500. This capped the total number of seats available for distribution among the 14 States at 493.

The Commission pointed out a significant demographic shift, stating, "The total population of these States has increased very considerably during the last ten years, resulting in the average population per parliamentary constituency rising from 732,654 in 1951 to 889,257 in 1961. Furthermore, this increase was not uniformly distributed across all States."

In light of the demographic changes identified in the 1961 Census, the Commission recognized that maintaining the existing 481 seats would unfairly disadvantage larger States like Uttar Pradesh, Andhra Pradesh, and Madras, each of which would have lost three seats, while Bihar would only lose one.

To address this issue, the Commission decided to increase the total from 481 to 490. Even then, larger States faced reductions: Uttar Pradesh, Andhra Pradesh, and Madras each lost two seats, while Bihar retained its allocation. The Commission concluded that even raising the total to the constitutional maximum of 493 would not alleviate the losses experienced by those States.

Consequently, under Order No. 1, Madras’ Lok Sabha representation was decreased from 41 to 39. The next phase involved determining the composition of the Madras Legislative Assembly.

Historically, the State adhered to a multiple of five, meaning each Lok Sabha constituency corresponded to five Assembly segments. Applying this formula would have led to: 39 × 5 = 195 Assembly seats. However, the existing Madras Assembly had 206 elected members, indicating that adhering to the prior multiple would result in a significant reduction in representation.

The Commission contemplated whether adjustments to the multiples were necessary across States. It observed that while the multiples generally increased as population decreased, this trend was not consistent. After careful consideration, it opted to maintain the existing multiple in all States, except for Madras.

In its order dated August 24, 1963, the Commission elaborated, "The Legislative Assembly of this State currently has 206 elective seats. Considering that its representation in the Lok Sabha will be reduced by two, we believe it prudent to raise its multiple from 5 to 6, assigning 234 seats to its Legislative Assembly."

The new calculation thus became: 39 × 6 = 234. Instead of a reduction, the Assembly was expanded, promoting effective representation and legislative balance.

At that time, other States did not experience similar adjustments. For instance, West Bengal maintained its multiple of seven, resulting in 280 Assembly seats. Similarly, Kerala, with 19 Lok Sabha seats, kept its multiple of seven for a total of 133 seats. Assam held onto nine, leading to 126 seats, while Uttar Pradesh continued with a multiple of five, yielding 425 seats.

This decision was not made arbitrarily; it was a strategic structural adjustment intended to uphold proportionality between parliamentary and Assembly representation while preventing a drastic reduction in the size of the State legislature. Even after six decades, the framework established by that 1963 decision remains intact, with the majority mark of 118, alliance dynamics, constituency sizes, and electoral strategies in Tamil Nadu continuing to function within this established structure.
