"I fully agree with Government of India decision. Every decision will cause some sort of a hardship to the people (in the short-term) but that cannot be a ground to say that we should allow to keep the black money in circulation," he said.

"They (the government) should take some steps (to bring back black money stashed abroad). I heard the Prime Minister as saying they have taken steps, shortly they may get it back but it's two years since they came to power," he said.
Hegde termed banning of cash donations to political parties as a "very good idea", and favoured government making it mandatory for such donors to share their PAN or Aadhaar number.
"It will (then) be easy to cross-check with Income Tax Department whether such a person could have made that much of a donation. Then it becomes extremely difficult for them to give false names and give donations. Some such radical step should be taken to see that this type of black money transactions are stopped," he said.
