What is delimitation, and why is it important? What challenges are associated with the delimitation exercise in India?

Delimitation is the exercise of redefining the 'territorial boundaries' under Article 82 of constitution. Important why important: (1) "principle of one vote - one value" (2) equitable representation of states in LokSabha (3) mandate under article 52 and article 352C [CSC/ST vej] (4) To ensure the census date is reflected properly (5) The IOTHA - New shall affirmed the change only rules delimitation.

Challenges: 1. Uneven growth of population (Total density rate - TFPI - replacement rate - TFPI) with leading to unequal representation of states in Loksha against South states 2. Leads to unequal in increase of North states against South states - with data showing variations between North(Uttar Pradesh, Haryana, Bihar, MP with +32 seats) and South (Karnataka, Tamil Nadu, Kerala with -19 seats) 3. Census has taken a close leading to drafting of delimitation 4. The order of delimitation cannot be challenged in courts. Thus, solutions like charging the status of experience of delimitation or weightage over system or checking for other 25 years and some modification.
