The Supreme Court today sought responses from the Centre and the Election Commission of India, ECI on a plea filed by the BSP challenging the use of EVMs without paper trail. A bench headed by Justice J Chelameswar issued notices to the government and the ECI and asked them to respond to the<br/>plea by 8th May, the next date of hearing.<br/><br/>During the hearing, senior advocate P Chidambaram, appearing for the BSP, told the bench that use of EVMs without<br/>voter-verifiable paper audit trail, VVPAT in the elections creates a serious doubt about the accuracy of voting and paper trail was required so that a voter can get a feedback of the vote cast by him. <br/><br/>He said, there were chances of tampering with EVMs as there were reports that both the hardware and software of these machines are vulnerable.<br/><br/>Intervening in the matter on Congress party's behalf, Senior advocate Kapil Sibal told the apex court that nowhere in the world, except in one country, these EVMs are being used, adding that every technology can be hacked.
