   • 2025 November 18, Krishnadas Rajagopal, “Kerala approaches Supreme Court to postpone Special Intensive Revision. The State said the 'cumbersome' SIR will coincide with the local bodies election and there are no human resources to conduct SIR and local bodies poll simultaneously”, in The Hindu‎:

     The Kerala government has moved the Supreme Court seeking a direction to the Election Commission (EC) of India to defer the conduct of the Special Intensive Revision (SIR) of the electoral rolls of the State. The State said the conduct of the “cumbersome” SIR process from November 4 to December 4 would coincide with the elections to the local bodies in Kerala. The simultaneous conduct of both exercises would not only strain human resource but also create an “administrative impasse” with no personnel left to take care of the day-to-day functioning of the government. The government said the simultaneous conduct of the SIR and the local body elections would be an “near- impossibility”.
