NEW DELHI, June 3 - As many as 13 political parties had questioned the reliability of the EVMs, but when the Election Commission threw open a challenge to prove that the machines could be tampered with none turned up for the dare.
The two parties � CPI(M) and NCP, which had accepted the challenge and appeared for the event held here today, also backed out at the last minute.
In a post-event conference, Chief Election Commissioner Nasim Zaidi maintained that the EVMs used by the EC are �non-tamperable� and with 100 per cent use of paper trail machines in all future elections the issue of tamperability of the machines �stands closed�.
With these remarks Zaidi made it clear that there would be no such challenge in future to test the reliability of the electronic voting machines (EVMs) used by the poll-conducting body.
The CPI(M) said it would not like to participate in the challenge, while the NCP too decided to opt out after raising some questions regarding EC�s �failure� to provide it with some details it had sought.
The NCP, however, has been extended another chance to return at a later date to hack the machines as an �academic exercise�, the CEC said.
The BSP and AAP had alleged that the machines used in the recent assembly elections were tampered with and favoured the BJP.
Over a dozen opposition parties, including the Congress, BSP, SP, DMK, JDU and the Left had urged the EC in April to revert to the paper ballot system in future elections, saying tampering allegations have created �trust deficit� on the reliability of the voting machines. � PTI
