The affidavit said that considering the need to impart greater accountability in funding of political parties as well as to maintain the anonymity of the donor, a mechanism of political funding by way of electoral bonds was introduced.
"Under the present system, electoral bonds can be issued only by an authorized bank, being the State Bank of India. All payments made for the issuance of the electoral bonds are accepted only by means of a demand draft, cheque or through the Electronic Clearing System or direct debit to the buyers' account. No Black money can, therefore, be used for the purchase of these bonds," it said.
