Chief Election Commissioner Sunil Arora on Wednesday ruled out voting through paper ballot after some parties asked him to consider their demand at a meeting with the commission in Mumbai ahead of the Assembly polls.

"A few political parties have asked about voting through paper ballot. We have told them it is not possible, it's history now," he said while interacting with media persons at the state guest house Sahyadri. "The EVMs cannot be tampered with. It is a standalone machine — different from other machines," said the CEC. Opposition parties have been asking for going back to ballot papers. The united opposition had even planned a protest march in Mumbai, but it didn't take place.
