VVPATs: Paper trail counting may delay poll results by 3hrs
As the Election Commission prepares for the rollout of VVPATs for elections across India, challenges posed by the process are coming to the fore.
One of the primary ones is delays of three hours or more due to mandatory counting of paper slips in some polling stations.
In this case, initial trends may be delayed to 11am. As of now, trends emerge by 9am.
Delay in results may pose other problems too
This can present other problems, like tension between supporters of different parties who generally gather at counting centres.
An internal EC committee is examining when the counting of paper trail should be scheduled. It is considering making paper trail verification mandatory in 4-5% of stations in each constituency.
The body is likely to release guidelines soon, including on how to choose the polling stations.
AAP had batted for paper trail counting at 25% stations
AAP, which led protests against EVMs, wanted paper trail counting at 25% of polling stations in each constituency. However, it would be impractical "as it would delay counting and declaration of results by as much as 26 hours", an official official.
