The Supreme Court will pronounce its judgement tomorrow on a batch of petitions challenging the constitutional validity of a provision in the Income Tax Act making Aadhaar mandatory for filing income tax returns and allotment of PAN.<br/><br/>A bench comprising Justices A K Sikri and Ashok Bhushan had on May 4 reserved the verdict on the pleas, challenging section 139AA of the Income Tax (I-T) Act, which was introduced through the latest budget and the Finance Act, 2017.<br/><br/>This section provides for mandatory quoting of Aadhaar or enrolment ID of Aadhaar application form for filing of income tax returns and making application for allotment of Permanent Account Number with effect from July 1 this year.<br/><br/>While opposing the government's move, the petitioners, including CPI leader Binoy Viswam, contended that the Centre cannot "belittle" the apex court's 2015 order holding the unique identification number as voluntary.<br/><br/>However,the Centre contended that Aadhaar was made mandatory for allotment of PAN to weed out fake cards which were used for terror financing and circulation of black money.<br/><br/>During the hearing, the Supreme Court had observed that it was yet to be tested whether Aadhaar violated protection of life and personal liberty granted under Article 21 of the Constitution, which was pending hearing for an authoritative pronouncement by a five-judge Constitution Bench.
