New Delhi, Aug. 18 -- The Election Commission of India (ECI) on Sunday called the Opposition's allegations of "vote theft" over the Special Intensive Revision (SIR) of Bihar's electoral rolls false and baseless, saying that the public is being misled and the Constitution undermined through these charges, even as it again called upon Congress leader Rahul Gandhi to provide proof of the alleged voter fraud or withdraw his remarks.
