"The government should come out with the names. The German and French authorities have already given a list of around 500 names to the Centre. I don't know why they are concealing things," Jethmalani told the media here.
"There is a steadied attempt not to disclose names," he added.
Earlier in the day, the SC asked the government to release all the names of the people who have stashed their black money in accounts abroad. The government has meanwhile indicated its willingness to place the entire list of names before the apex count by Wednesday morning.
The government is building pressure particularly on Switzerland, seeking details of Indians who have parked unaccounted for money in the Alpine country's highly secretive banks. It has quickly implemented a Supreme Court directive to set up a high-powered special investigation team, headed by retired judge MB Shah, to look into the issue.
While there are no official estimates, Global Financial Integrity (GFI), a Washington-based think-tank, has estimated that Indians had parked USD 462 billion in overseas tax havens between 1948 and 2008.
