- The upcoming delimitation exercise poses a serious federal dilemma for India, pitting principles of population-based representation against states that successfully controlled population growth (particularly in Southern India). - States that prioritized family planning and population stabilization fear facing a reduction in their political weightage and representation in Parliament, leading to concerns of marginalization. - The freeze on delimitation based on 1971 census data (extended through the 84th Constitutional Amendment) was designed to avoid penalizing states for family planning, but its upcoming expiration brings these tensions back to the forefront. - A balanced approach is needed to reconcile democratic equity (one person, one vote) with federal integrity and cooperative federalism, ensuring states are not penalized for effective social policy implementation. **Introduction** The article explores the federal dilemma surrounding the impending delimitation of parliamentary constituencies in India.
