The PIL filed by the 'Rashtriya Brashtachar Virodhi Janshakti' also requested the high court to monitor such inquiry and direct the authorities to register an FIR against those who have deposited unaccounted wealth in foreign banks.
The petition referred to media reports which claimed that between 2002 to 2006, black money to the tune of Rs 70,00,000 crores have been siphoned off from the country and stashed away in banks abroad.
The NGO said that both the governments had not put in efforts to retrieve the black money lying in foreign banks, which could be used to cover the budget deficit and for the development of the nation.
The PIL will come up for hearing after the summer vacation.
