The Election Commission of India (ECI) recently commenced the process of delimitation of state assembly and parliamentary constituencies of Assam.
The last delimitation in Assam happened in 1976.
The current delimitation exercise is being conducted based on the 1971 Census.
Delimitation is the process of redrawing boundaries of state assembly seats and the Lok Sabha seats to represent the changing population numbers.
The main purpose of the delimitation exercise is to ensure equal representation to equal segments of a population.
Since the population does not increase uniformly, delimitation reflects the changes in the distribution of the population over a period of time.
The Delimitation Commission is an independent commission responsible for conducting delimitation exercises.
It is set up by the Central Government under the Delimitation Commission Act.
This commission jointly works with the Election Commission of India (ECI) to conduct the delimitation.
It includes a retired Supreme Court Judge, the Chief Election Commissioner and the respective state’s State Election Commissioners.
Article 82 of the Constitution requires the Indian Parliament to enact a Delimitation Act after every Census.
Once this Act is in force, the Central Government must set up a Delimitation Commission.
A total of 4 Delimitation Commissions have been set up in the past (1952, 1963, 1973 and 2002).
The 2002 Act did not make any changes in the total number of Lok Sabha seats or their apportionment between various states.
It left out Assam, Arunachal Pradesh, Nagaland and Manipur from the delimitation exercise due to security concerns.
The Indian Government reconstituted the Delimitation Commission for these 4 states and the union territory of Jammu and Kashmir in 2020.
The last delimitation exercise that changed the state-wise composition of the Lok Sabha happened in 1976.
It was conducted based on the 1971 census.
The delimitation exercises were not conducted frequently in the recent past.
This is because the Indian Constitution mandates that the number of Lok Sabha seats allocated to a state should be (as far as it is achievable) same for all states.
To address this issue, the Indian Constitution was amended in 1976 to suspend the delimitation until 2001.
Another amendment was enacted to delay the delimitation exercise further until 2026.
