New Delhi: The Supreme Court on Friday will hear the plea filed by the Bahujan Samaj Party (BSP) and lawyer Manohar Lal Sharma, seeking a thorough investigation into the tampering of the Electronic Voting Machines (EVMs) by US-based scientists.

In his petition, Sharma claimed that in the April Assembly elections of five states, the EVMs were allegedly tampered.

Earlier, the top court had issued a notice to the Union Government seeking a reply into Sharma`s plea.

If any specific allegation with material facts is presented, it (the allegations) will be looked into with all seriousness on administrative sides.
