New Delhi, Oct 23 (PTI) In the backdrop of some opposition parties raising doubts about the functioning of Electronic Voting Machines (EVMS), the Election Commission today said no party has been able to prove that the machine could be tampered with.

"We are completely satisfied with the EVMs. If there is a representative or a political party wanting to come and see our demonstration, they are always welcome. Everything this Commission had to explain about EVMs, we have done", Chief Election Commissioner Navin Chawla told reporters when asked about complaints on EVMs by some political parties.

Pointing out that EC had already give many clarifications on the functioning of EVMs, he said the Commission had also made two demonstrations and no political party could prove the tamperability of the machines.

The CEC said the matter was also pending before the Delhi High Court.
