Mr Rohatgi said there were instances that one person was having a number of PAN cards and these fake cards were being used to divert funds to shell companies.
To this, however, the bench asked the Attorney General, "Is this the remedy that you need to have Aadhaar for having PAN? Why has it been made mandatory?"
Responding to the Court’s question, Mr Rohatgi said they had, even earlier, found people procuring SIM cards for mobile phones on basis of fake identity cards and the top court had asked the government to keep a check on it.
Through an amendment to the tax proposals in the Finance Bill of the Budget for 2017-18, the government has made Aadhaar mandatory for filing income tax returns and provided for linking of PAN with Aadhaar to curb tax evasion through use of multiple PAN cards.
