Union Home Minister Amit Shah chaired the 31st [1] Southern Zonal Council meeting at a seaside resort on the outskirts of Chennai, Tamil Nadu.

The gathering serves as a critical platform for the central government and southern states to resolve inter-state disputes and align on regional development.

Shah led the discussions with the participation of five [2] southern states and three [3] Union Territories. Key attendees included chief ministers C. Vijay, D. K. Shivakumar, and Chandrababu Naidu.

A primary focus of the meeting involved water sharing and infrastructure projects. Discussions specifically addressed the Cauvery water dispute and the Mekedatu project, which remain points of contention between neighboring states.

Delimitation of parliamentary constituencies also dominated the agenda. Karnataka representatives raised concerns regarding the potential redistribution of seats based on population changes. The discussion touched upon the historical freeze of the Lok Sabha at 543 seats [5], a measure that lasted for 25 years [6].

Some participants discussed the possibility of using the 1971 Census [4] as the basis for delimitation to ensure that states with successful population control measures are not penalized with fewer representatives in parliament.

The council meeting aimed to provide a structured dialogue to mitigate friction between the Centre and the southern administrations on these systemic issues.

The 31st Southern Zonal Council meeting focused on water sharing, infrastructure projects, and delimitation.

The focus on the 1971 Census and the 543-seat freeze highlights a deep-seated tension between northern and southern India. Southern states have historically implemented more effective population control; using current population data for delimitation would likely shift political power toward the more populous northern states, reducing the southern region's influence in the Lok Sabha.
