To be or not to be is no longer the question. The question has now been pushed into the details \u2014 what form\u00a0should it exist in and how should it be implemented. We're talking about\u00a0Aadhaar \u2014 the controversial, much-debated, biometrics-based identification system for 1.3 Bn Indians.\r\n\r\nAfter months of waiting, the landmark judgement of the\u00a0Supreme Court (SC) on Aadhaar's constitutionality is finally out and, as expected, the ruling is in favour of the Aadhaar Act. The SC ruled that\u00a0Aadhaar is mandatory only for filing income tax returns and for the allotment of PAN.\u00a0It won\u2019t be essential for opening bank accounts or getting SIM cards from telecom operators.\r\n\r\nWelcoming the verdict, Nandan Nilekani, the ex-chairman of UIDAI who coined the term 'Aadhaar',\u00a0tweeted, "This is a landmark judgement in favour of #Aadhaar. More than just opining on the constitutionality of the act, the SC has unequivocally validated the founding principles for Aadhaar. Aadhaar is a unique identity project that is critical to the developmental goals of the nation."\r\n\r\n\r\n\r\nThe constitutional validity of Aadhaar, backed by the Aadhaar Act, remained unquestioned at large with four out of five judges on the SC Constitution bench \u2014 Chief Justice of India Dipak Misra and Justices A K Sikri, A M Khanwilkar, and Ashok Bhushan \u2014 favouring the Aadhaar Act.\u00a0The fifth judge \u2014 Justice Dhananjaya Y Chandrachud \u2014 however, said that Aadhaar is wholly unconstitutional.\r\n\r\nMaking some starkly different observations from the other judges,\u00a0Justice\u00a0Chandrachud stated that it can not be the institutional responsibility of UIDAI to protect the data of citizens.\r\n\r\nThe Aadhaar leaks\u00a0and the right to privacy arguments were not enough to get the bench to declare the Aadhaar Act as unconstitutional.\r\n\r\nWhile the Aadhaar verdict has been viewed as being in favour of the central government and the\u00a0Unique Identification Authority of India (UIDAI), it also provides some relief to the petitioners.\u00a0Constitutional validity notwithstanding, the bench has fine-tuned the Act, striking down some of its provisions.\r\n\r\nThe Court has struck down the Sections 33(2), 47 & 57 Of the Aadhaar Act.\r\n\r\nSatisfied with the defence mechanism improvement against the Aadhaar data leaks, the SC has also defined who has the authority to seek Aadhaar data and who doesn't.\r\n\r\nSpeaking to Inc42, Vivek Wadhwa, Distinguished Fellow, Harvard Law School and\u00a0Distinguished Fellow and professor, Carnegie Mellon University Engineering, Silicon Valley\u00a0responded, "I\u00a0think that the Supreme Court has made a very wise decision. Aadhar is very important, it has provided identity to hundreds of millions of people who lacked this and were left out of the formal economy. But when the private industry started using it and its privacy was compromised, things went too far."\r\nThere needs to be a balance and the judgment mandates this. If Aadhar had been left unchecked, India would have gone the way of China and become a surveillance state, in which both government and industry collude to control and spy on the population, says Wadhwa.\r\nAadhaar Verdict: What\u2019s The Decision?\r\nHere are the salient points of the SC's 1448-page Aadhaar Verdict:\r\n\r\n \tThe SC struck down the provision that prevented individuals from filing cases under the Aadhaar Act. Now, Individuals too can approach courts to file cases under the Act.\r\n \tIt struck down Section 57 of the Aadhaar Act. Now, private companies won\u2019t have the authority to demand people's Aadhaar IDs. In his judgement, Justice Chandrachud instructed telecom operators to delete all data they have collected from users.\r\n \tThe SC struck down Section 33(2), which permits the disclosure of Aadhaar data for national security issues.\r\n \tPeople can't be denied any government benefits on grounds of having an Aadhaar card. So, Aadhaar IDs can't be mandatory for children to avail of midday meals or admission to public schools.\r\n \tAadhaar has been made mandatory only for filing income tax returns and for the allotment of PAN.\u00a0It won\u2019t be essential for opening bank accounts or getting SIM cards from telecom operators.\r\n \tAadhaar-based authentication data should not be stored beyond six months. The current rule that it can be archived for five years has been struck down\r\n\r\nSpeaking of the Aadhaar verdict, Gopal Bohra, Partner, N.A Shah Associates\u00a0told Inc42,\u00a0\u201cThis judgement of Apex Court will set the guidelines on various ongoing controversial areas where the\u00a0use of Aadhaar was made mandatory and consequential concern over data privacy.\u201d\r\n\r\nHe added that the Apex Court has applied balanced approach making mandatory use of Aadhar at certain places such as filing of income tax return atleast for those individuals who are eligible to obtain Aadhar number and also restricting the data sharing with private parties. This ruling making mandatory Linking of Aadhaar with PAN will help the government in curbing tax evasion.\r\n\r\nHowever, as expected, people have come up with mixed reactions over the Aadhaar verdict. A Twitter user pointed out that as per the verdict, Aadhaar IDs won't be essential anymore for opening bank accounts; however, it's been made essential for linking PAN, and PAN is essential for the opening bank accounts. So, the Aadhaar verdict contracts itself.\r\n\r\nBhavin Patel, Co-founder, and CEO LenDEnClub\u00a0told\u00a0Inc42, \u201cThis verdict is really good that the Supreme Court has accepted Aadhaar\u2019s constitutional validity. There have been many questions regarding the data security, the surveillance state, privacy problem etc. and with today\u2019s verdict, the air is now clear around those concerns."\r\n\r\nHowever, "the Supreme Court highlighted some of the flaws in Aadhar law due to which private companies have been barred from using Aadhar for identity verification. This may affect the fintech as well as other financial companies which uses the only Aadhar as their identity verification mechanism," added Patel.\r\n\r\n \r\n\r\nThe Aadhaar Case Hearing\r\n\r\n\r\n\r\nThe timeline has been prepared by Shreya Ganguly\r\n\r\n\r\n \r\n\r\nThe Aadhaar Case hearings ran for 38 days \u2014 the second-longest hearing in India\u2019s judicial history after the Kesavananda Bharati Case of 1973 \u2014 and the case was deliberated for five months.\r\n\r\nIn January 2018, the Constitution bench had started the final hearing on a batch of petitions clubbed with the Puttaswamy case that challenged the Aadhaar Act (introduced in Parliament as the Money Bill) on grounds that it violates an individual\u2019s fundamental right to privacy.\r\n\r\nIt\u2019s worth noting that the government had earlier made Aadhaar mandatory for availing a host of benefits such as schemes for the below poverty line category, LPG subsidies, midday meals in schools, etc. This was followed by the diktat that private companies would have to ask their customers\/users to link their Aadhaar with services such as banking, payments, SIM cards, etc.\r\n\r\nThe Supreme Court later clarified that it had never given any such order.\r\n\r\n\r\n\r\nA former Judge of the Karnakata High Court, Justice K S Puttaswamy, along with a host of other petitioners, opposed the government\u2019s move to make Aadhaar mandatory for availing social security benefits and other services.\r\n\r\nThe Justice K S Puttaswamy case writ petition (civil) no(s) 494\/2012 has already made history as the nine-judge bench of Supreme Court, while hearing the case, recognised the Right to Privacy as a fundamental right last year. Today\u2019s SC judgement has now sealed the legitimacy of\u00a0Aadhaar, while restricting the scope of its uses \u2014 a balanced decision overall.
