With hardly a month left for the Lok Sabha elections, 21 opposition parties have approached the Supreme Court. The reason for the visit was to ask for Electronic Voting Machines to be tinker-proof. The court is scheduled to hear their petitions tomorrow.

The opposition has demanded more safety norms and strict standards for EVMs in the light of EVM tampering cases. They have also asked for 50 percent of VVPAT (Voter Verified Paper Trail Audit Machines) to be tallied with the voting machines.

The opposition parties that went to court include the Congress, Telagu Desam Party, NCP, Aam Aadmi Party, the Left parties, Bahujan Samajwadi Party and Samajwadi Party amongst others.

Since the 2017 assembly elections in which the BJP emerged victorious in Uttar Pradesh with a huge number, the opposition parties had asserted that the EVMs were tampered with. Bahujan Samajwadi Party leader, Mayawati has called for a return to paper ballot system.
