The Delimitation commission or Boundary commission of India is a commission established by the Government of India under the provisions of the Delimitation Commission Act. The main task of the commission is redrawing the boundaries of the various assembly and Lok Sabha constituencies based on a recent census. The representation from each State is not changed during this exercise. However, the number of SC and ST seats in a state are changed in accordance with the census. The present delimitation of constituencies has been done on the basis of 2001 census under the provisions of Delimitation Act, 2002.

The Commission is a powerful and independent body whose orders cannot be challenged in any court of law. The orders are laid before the Lok Sabha and the respective State Legislative Assemblies. However, modifications are not permitted.

Past Commissions[edit]

Delimitation commissions have been set up four times in the past — 1952, 1963, 1973 and 2002 — under Delimitation Commission Acts of 1952, 1962, 1972 and 2002.

The union government had suspended delimitation in 1976 until after the 2001 census so that states' family planning programs would not affect their political representation in the Lok Sabha. This had led to wide discrepancies in the size of constituencies, with the largest having over three million electors, and the smallest less than 50,000. [1]

Delimitation Commission of 2002[edit]

The most recent delimitation commission was set up on 12 July 2002 after the 2001 census with Justice Kuldip Singh, a retired Judge of the Supreme Court as its Chairperson. The Commission has submitted its recommendations. On December 2007, the Supreme Court on a petition issued notice to the central government asking reasons for non implementation. On 4 January 2008, the Cabinet Committee on Political Affairs (CCPA) decided to implement the order from the Delimitation Commission.[2] The recommendations of the Commission was approved by President Pratibha Patil on 19 February. This means that all future elections in India for states covered by the commission will be held under the newly formed constituencies.[3]

The present delimitation of parliamentary constituencies has been done on the basis of 2001 census figures under the provisions of Delimitation Act, 2002. However, the Constitution of India was specifically amended in 2002 not to have delimitation of constituencies till the first census after 2026. Thus, the present constituencies carved out on the basis of 2001 census shall continue to be in operation till the first census after 2026.[4] The assembly election in Karnataka, conducted in three phases in May 2008, was the first to use the new boundaries as drawn by the 2002 delimitation commission.[5]

Apportionment of Parliamentary and Assembly seats[edit]

Up until 1976, after every Indian Census the seats of Lok Sabha, Rajya Sabha and Vidhan Sabha were re-distributed respectively throughout the country so as to have equal population representation from every seat. The apportionment was done thrice as per 1951, 1961 and 1971 population census. However, during The Emergency, through Forty-second Amendment the government froze the total Parliamentary and Assembly seats in each state till 2001 Census.[6] This was done mainly due to wide discrepancies in family planning among the states and thus giving time to states with higher fertility rates to implement family planning to bring the fertility rates down.[6]

Even though the boundaries of constituencies were altered in 2001 to equate population among the parliamentary and assembly seats; the number of Lok Sabha seats that each state has remained unaltered since 1971 census and may only be changed after 2026 as the constitution was again amended (84th amendment to Indian Constitution) in 2002 to continue the freeze on total number of seats in each state till 2026.[7] This was mainly done as states which had implemented family planning widely like Kerala, Tamil Nadu and Punjab would stand to lose many parliamentary seats representation and states with poor family planning programs and higher fertility rates like Uttar Pradesh, Bihar and Rajasthan would adversely gain many of the seats transferred from better performing states.[8]
