SG Mehta takes the bench through a report by ADR on sources of donations to political parties in 2018.

SG Mehta: Every political parties need clean money to show expenditure etc. How do they do that? I deposit 100 cr as a party saying that so many 1000 people donated 19,000 rs to me each. If it is below 20,000 I'm not supposed to reveal identity of donor.
