On Saturday last, the Commission had announced that the challenge to hack and tamper with the electronic voting machines (EVMs) would take place on June 3 and the seven recognised national and 49 state parties can apply by May 26, 5 pm, to participate in the challenge.
But till tonight, nobody has applied, Commission sources said.
After the Uttar Pradesh assembly polls, the BSP and the AAP had questioned the reliability of the machines.
A demand of the AAP to tamper with the motherboard of the machine was rejected by the Commission today.
It said change in circuits would mean the EVM is no longer the one used by the Commission.
