"The CPI (M) team expressed complete satisfaction and suggested that commission should hold such demonstration and awareness sessions proactively".
He said, CPI (M) clarified doubts and NCP wanted to participate only in an academic exercise.
Asserting that the EVMs aren't hackable, the Uttarakhand High Court on Friday took strong exception to criticism of the Election Commission by political parties, saying the right to freedom of speech and expression does not permit leveling of unsubstantiated charges against constitutional bodies.
However, the EC today informed it will provide them with one of the 14 EVMs now in their custody, Vandana added. "But you've to prove that they're tampered without opening it under four hours", Bharadwaj said.
The Election Commission today held the EVM hacking challenge, starting with a detailed demonstration on the various security checks in the machine.
"Serial numbers of battery and memory are crucial parts of an Electronic Voting Machine and should have been provided, as it was a specific request and these were very much available with the EC", she said in letter to Chief Election Commissioner Nasim Zaidi on Saturday. The EC will use randomly selected 14 EVMs, which were used in recent Assembly elections in UP, Punjab and Uttarakhand.
After receiving many complaints as regards the usage of EVMs for elections, the Election Commission issued a press release on May 20 in an attempt to allay the parties' fears.
The court pointed out that the work to build EVM machines is done by government agencies and the Election Commission is a constitutional body.
The machines were also at the centre of a controversy in 2004, after the BJP was shocked by the Congress in that year's general elections.
The EVM challenge has been organised by the Commission to clear the doubts of non-NDA opposition political parties who had alleged EVM manipulation.
ECI officials say, the rules and procedures in place regarding such a challenge did not allow that.
