The Election Commission of India (ECI) on Thursday directed the chief electoral officers of 16 states and 3 Union Territories to commence the third phase of the Special Intensive Revision (SIR) of electoral rolls, a controversial exercise that will cover 367 million people between the end of May and the beginning of December as part of a staggered schedule.The Election Commission announced the rollout of the SIR Phase III of electoral rolls across 16 states and 3 UTs (Hindustan Times)Himachal Pradesh, Jammu & Kashmir and Ladakh were kept out of the current phase due to ongoing census operations and weather conditions in snow-bound areas, as per the official order issued by the ECI.First launched in Bihar late last year, SIR triggered a major electoral and legal controversy, especially after it led to the disenfranchisement of 2.71 million people in West Bengal during assembly polls last month.“I appeal to all electors to enthusiastically participate in the Phase III of Special Intensive Revision and fill their Enumeration Forms. SIR is being conducted with the objective to ensure that only eligible voters are included in the electoral roll and no ineligible names are included,” said chief election commissioner Gyanesh Kumar.Also Read: Why Election Commission left out J&K, Ladakh and Himachal from SIR rolloutDelhi is among the regions where SIR will be conducted.In the Capital, the exercise will start on June 30, the draft roll released on August 5, and the final roll on October 7.Delhi currently has 14.8 million people on its voter rolls.
