Elections are scheduled for December 13 and 17. Ahmedabad district has 21 Assembly constituencies and 4,856 polling stations.
"We have 9,934 ballot units (BU) and 7,887 control units (CU) and all these have been checked and certified as fit for the elections by the engineers of Bharat Electronic Limited, the manufacturer of EVMs," Nehra said.
On the election day, a "MockPoll" test would be carried out by the officials. After three levels of checking, the EVMs will be sealed in the presence of polling agents of candidates and EC-appointed observers.
"We will be using the kind of tamper-proof EVMs which have never been used anywhere in the world yet and which guarantee free and fair election," Nehra said.
