Why should Aadhaar be linked to tax returns?

Will linking Aadhaar card to PAN raise security issues and invade privacy of citizens?

The Centre defended linking Aadhaar with permanent account number (PAN) in the Supreme Court, saying that the government is entitled to ask for identification details of citizens.

Attorney General Mukul Rohatgi argued that petitioners cannot live in a vacuum and cannot ask to remain invisible. People don't live in the Himalayas, he added.

Whereas, opposing Centre's move on Aadhaar, senior counsellor Arvind Datar said that any encroachment on human liberty must be resisted and government's move is draconian in nature.
