Know all about Delimitation Commission.

By Sudheer Kumar K|Updated : June 23rd, 2021

In June 2021, PM Modi invited J&K leaders which led to speculation of possible scheduling of elections. On August 15, 2020, Prime Minister Narendra Modi said elections would be held in J&K after the delimitation process in the Union Territory was over.

J&K was reorganized into Union Territory and there would a change the population composition. For general elections to the newly formed UT to be held, delimitation of assembly constituencies is essential to reflect the changes in population. Now, let us understand what is Delimitation and Delimitation Commission.

Constitutional Provisions

Articles 82 and 170 of the Indian Constitution provide for the readjustment and division of each State into territorial constituencies of both parliamentary and assembly based on the 2001 census by such authority and in such manner as Parliament may by law determine.

Also, Articles 330 and 332 provide for re-fixing the number of seats reserved for SCs and STs in the Lok Sabha and State Legislative Assemblies based on the 2001 census.

Why Delimitation of Constituencies?

Delimitation of territorial constituencies is essential to ensure fair representation and equal division of territorial constitutions in such a manner that the ratio between the population of each constituency and the number of seats allotted to it is the same throughout the state. That means, to ensure uniformity of representation between different constituencies in the state.

The following are the reasons that would result in changes in sizes of electoral constituencies even within the same State:

  • Uneven growth of population in many constituencies in various parts of the country as well as within the same State
  • Continuous migration of people or electorate from one place to another particularly from rural areas to urban areas


  • Delimitation is the act or process of redrawing the limits or boundaries of territorial constituencies in a country to reflect population changes.
  • In 1950-51, the first delimitation exercise was carried out by the President in consultation with the then Election Commission.
  • In 1952, the first Delimitation Commission Act was passed. Under the Act, Parliament set up the Delimitation Commission in 1952 for the purpose of redrawing the constituencies.
  • The last Delimitation Commission was set up in 2002 under the Delimitation Commission Act 2002.
  • Parliament, through 91st Amdement Act, has frozen the number of seats and state-wide distribution of seats in the Loksabha and state assemblies till 2026.
  • However, a new delimitation commission can adjust the geographical boundaries of each seat within the frozen limits.
  • Since, Census is conducted after 10 years, the next Delimitation Commission would be after 2031 Census.

Delimitation Commission

  • The President of India appoints the Delimitation Commission, which works in tandem with the Election Commission of India.
  • Composition:
    • Retired Supreme Court judge
    • Chief Election Commissioner
    • Respective State Election Commissioners
  • Functions:
    • To determine the number and delineate boundaries of constituencies to make population of all constituencies equal.
    • To identify seats reserved for SCs and STs, wherever their population is relatively large.
  • The orders issued by the Delimitation Commission is final and cannot be challenged in any court.
