The Supreme Court on Monday asked the opposition leaders to file their reply on the Election Commission's affidavit within a week on their plea regarding Voter Verifiable Paper Audit Trail (VVPAT) slips in Lok Sabha polls.
The opposition leaders led by Andhra Pradesh Chief Minister Chandrababu Naidu had sought that VVPAT slips of at least 50 per cent of voting machines in each assembly constituency be checked randomly during Lok Sabha polls next month.
A bench headed by Chief Justice Ranjan Gogoi asked senior advocate A M Singhvi, appearing for Opposition leaders, to file the reply by next Monday.
The poll panel had on Friday last sought dismissal of the petition.
In its affidavit, the EC had asserted in the apex court that the opposition leaders have been unable to raise any ground for altering the existing system of random counting of VVPAT slips from one polling booth per assembly segment, which was "found to be most suitable" after due studies and tests.
