“According to Swiss National Bank statistics, at the end of 2012, Indians had 1.34 billion Swiss francs (Rs 9,000 crore) stashed in the European country’s banks. This doesn’t include money that Indians may hold in Swiss banks in the names of others or trusts.

To be sure, the amount has shrunk from over 2 billion Swiss francs at the end of 2011 after an anti-corruption movement in India focused public anger against black money.” (ET report)

The government of India is telling that despite maximum pressure on these European governments, it is not able to get the name of persons, corporates etc. who have stashed these amounts.
It may be true, may not be true. But one thing is sure that the government is not serious, since many of those who stashed the money are of the highest echelon, may be many of the top politicians also. The government has not published the names of those persons, whose list is already with the government, on the plea that bilateral agreements does not allow them to be published.
What the government is actually doing is giving a chance to these tax evaders and holders of black money to safely change it to other places/countries, where the government has not moved so far. By the time the details of the accounts with the name of holders are received, there will be no money in the accounts for the government to take any action,even if it wants.
