Timeline
The Delimitation Commission of India is the body responsible for redrawing the boundaries of parliamentary and state assembly constituencies so that the number and shape of seats keeps pace with changes in population. It is constituted by the Government of India from time to time and works separately from the Election Commission of India, which conducts the elections held within the constituencies that the Delimitation Commission defines.
What the Delimitation Commission Does
The Commission's core task is to readjust the boundaries of constituencies for the Lok Sabha and state legislative assemblies. This exercise is triggered by fresh Census data, since constituency boundaries are meant to reflect current population distribution rather than the distribution that existed decades earlier.
Commissions Constituted So Far
According to Government of India records, four Delimitation Commissions had been constituted till December 2023. The most recent of these — the Fourth Delimitation Commission — was set up in 2002 under the Delimitation Act, 2002, and carried out its exercise using data from the 2001 Census.
The Fourth Delimitation Commission was headed by a retired judge of the Supreme Court of India as its chairperson, reflecting the quasi-judicial character that the government has attached to the delimitation process.
Finality of the Commission's Orders
A distinctive feature of the delimitation process is that once the Commission's orders are notified, they cannot be challenged in any court of law. This finality is intended to prevent prolonged litigation from delaying the implementation of revised constituency boundaries ahead of elections.
How It Relates to the Election Commission
The Election Commission of India is a separate authority whose primary role is to superintend, direct and control elections to Parliament, state legislatures, and the offices of President and Vice-President. Its functions include issuing the Model Code of Conduct, recognising political parties, administering electoral symbols, and overseeing the declaration of results. The Election Commission is also associated with delimitation-related decisions, which places the redrawing of constituency boundaries within the wider institutional framework that governs how India's elections are organised, even though the dedicated exercise of redrawing boundaries has, in practice, been carried out through separately constituted Delimitation Commissions such as the one set up in 2002.
