INTRODUCTION

This is one of the most important decisions concerning the right to privacy and the legality of Aadhaar. Aadhaar is a unique 12-digit identification number available to all residents of India through their biometric and demographic details. These details are obtained through Unique Identification Authority of India (UIDAI). Initially formed in January 2009 under Planning Commission, UIDAI became statutory body in 2016 through Aadhaar Act under Ministry of Electronics & IT. The details contained in an Aadhaar Card include Name, Date of Birth, Aadhaar Number, Gender, Photo, Address and QR Code. The main purpose of the Aadhaar card is to ensure that welfare resources reach poor and needy people of India effectively through the state.

This decision is important because it protects a very fundamental right that is necessary for all. Nobody likes to have their personal lives being unnecessarily disturbed. In today’s technologically advanced world, it becomes all the more necessary to provide such protection.

BRIEF FACTS OF THE CASE:

A plea was filed at the Supreme Court in 2012 by retired High Court’s Judge K.S. Puttaswamy, arguing the constitutionality of Aadhaar on the basis that it violates the right to privacy of an indication. In this Public Interest Litigation, the petitioners question the fact that the scheme violates the fundamental rights of the people of the nation. Up to now, around one billion Indians have enrolled themselves in the Aadhaar scheme wherein the people receive an exclusive 12-digit number depending upon their biometrics including eye scan and fingerprints. The procedure of enrollment in the Aadhaar scheme has become mandatory in order to file for taxes, opening bank accounts, making loans, trading property and even purchasing items above 50,000 rupees. Several decisions had been made before but it was only in 2016 that the Aadhaar Bill was brought into operation after which the petitioners have filed a fresh challenge against the Aadhaar Bill.

In mid 2017, the former union minister and Congress Party leader Jairam Ramesh challenged the decision of Aadhaar bill being a money bill in the Supreme Court. It was finally on 24^th August 2017, a nine judge bench of apex court gave the verdict that the right to privacy considered to be a fundamental right under Article 21 of the Constitution of India.[3]

LEGAL ISSUES

1. Whether the ‘right to privacy’ is an intrinsic right under the ‘right to life and personal liberty under Article 21[4] and the various other freedoms enshrined under Part III of the Indian Constitution?

2. Whether the decision made by the Court in M. P. Sharma and Others Satish Chandra, District Magistrate, Delhi[5], and Others and Kharak Singh v. The State of UP[6] is correct in law?

CONTENTION BY PARTIES ON ISSUES

PETITIONER’S ARGUMENTS:

The individuals who submitted the petition claimed that the way the Aadhaar Act was designed is inherently based on probability. The Act is intended to offer greater support, benefits, and assistance to citizens. However, there is a possibility that instead of reaching the intended groups of people who are meant to receive these benefits, subsidies, and services, they might exclude those individuals and prevent them from accessing the support they require.

The main arguments were that the Act could potentially strip away certain rights and freedoms that are protected under the Indian Constitution. Enforcing the Aadhaar Act rigorously could lead to significant problems because it conflicts with the Fundamental Rights outlined in the Indian Constitution, which are meant to safeguard the rights of the citizens.

The Aadhaar system was seen as contradicting the Constitution and could enable the government to turn into a surveillance state, where it could monitor citizens’ activities. This would occur because the system gathers detailed information from each individual, forming a vast electronic database that could be used for surveillance purposes.[7]

It was also argued that the citizens’ right to privacy was being compromised. The Right to Privacy is a crucial component of Article 21 of the Indian Constitution[8], which guarantees the Right to life and liberty. The Act imposes restrictions that are not justified under Article 19 as reasonable limitations[9]. If any restrictions are imposed, they should satisfy the conditions laid down in Article 14 and Article 19 of the Indian Constitution[10]. It is also essential that the law imposing such restrictions be fair, just, and reasonable.

In this case, the limits set by the government through the Aadhaar Act are not considered reasonable and are instead seen as unfair and not justified. There is no proper way to classify people because the way the law divides society does not connect with the goal of the law. The information asked from the citizens broke their trust and privacy. The purpose of the Act was not connected to the information that the citizens wanted to collect. The Act also grouped people into categories depending on their religion. Classifying people based on their religion not only treated them unfairly but also made them share their religious beliefs, which goes against Article 25 of the Indian Constitution[11]. Also, the Act required people to have Aadhaar Cards in order to get some benefits provided by the government to citizens as per the Act. Mandating Aadhaar Cards will allow the government to keep a close watch on citizens, which could be seen as a violation of their right to privacy as protected by Article 21 of the Constitution[12]. Respecting privacy is a fundamental right protected by the Constitution, and when this right is broken, it seriously harms people’s lives and dignity, which are basic rights everyone should have.[13]

RESPONDENT’S ARGUMENTS:

The people who signed the affidavit said that the reason they introduced the Act was to make sure every citizen who is qualified to get government benefits and subsidies actually receives them and isn’t left out.

The respondents also argued that the Aadhaar Act does not require any information that could infringe on a person’s Right to Privacy. The respondents said that the Act doesn’t ask for much personal information from citizens, which could allow the state to monitor them. The respondents also mentioned that the Act is asking citizens for certain demographic information. Include the name, date of birth, gender, address, mobile number, and email address of the citizens. Citizens could choose whether to give their mobile number and email address to the State. These two details were only needed to send important information to the AMH and to provide a One Time Password (OTP) for verifying their identity. The information that the Act wants to get from the citizens is already available to everyone.

The respondents also mentioned that the Act, under Section 2(k)[14], clearly says that the regulations cannot ask for information such as race, religion, caste, tribe, ethnicity, language, income, records of entitlement, or medical history from citizens. Therefore, according to this Act, citizens cannot be asked for any sensitive information through it. Based on the section mentioned earlier, there is very little room to get more demographic information. Even the biometric data the law wants from citizens is limited to just their fingerprints and an iris scan.

The respondents said that Aadhaar functions as an identity card, and about 92 crore people use it to access different social programs and get benefits from the government for their citizens. It’s a document that many people use, and if it’s limited, it could cause issues for the people who rely on it. Aadhaar is a document that helps the government find and stop duplicate entries and fake identities in lists of people who are supposed to benefit from services. It also allows workers under MONREGA and pensioners to get their wages and pensions every month.

The respondents also disagreed with the privacy concern, explaining that the data collected under the Act is safe because it is encrypted at the source. They also mentioned that all citizens’ biometric information is stored by the government on servers owned by the Government of India. The Indian government’s servers have a security level that is among the best globally. Using an Aadhaar number can help prevent the use of duplicate or fake cards to get government benefits. Citizens are asked to provide their Aadhaar number to avoid this. Aadhaar can also help reduce the role of middlemen who take a share of the government’s subsidies meant for a specific group of people. Government subsidies mostly cover things like food, fertilizer, water, electricity, education, and healthcare. The government often offers these items and services for less money than what people usually pay in the market. To make this initiative work well, Aadhaar can be used. Aadhaar can help make sure that subsidies given by the government reach the right people on time and stop money from being lost or misused. This step can save a huge amount of money that is wasted due to leaks. The government has found millions of duplicate ration cards, and Aadhaar can help ensure that the benefits and subsidies meant for specific groups of people actually reach them.[15]

COURT’S REASONING AND ANALYSIS

The case was heard by a panel of three judges in the Court, which on August 11, 2015, decided to refer the matter to a bigger panel of judges in the Court. On July 18, 2017, a panel of five judges decided that the case should be heard by a larger panel of nine judges, and the final judgment was given on August 24, 2017.

• Chandrachud (on behalf of himself, C.J. Kehar, J. Agrawal and J. Nazeer believed that the Constitution needed to change in order to deal with the challenges people face in a time when technology controls almost every part of our lives. It is crucial for the Courts to understand and define the idea of individual liberty, especially when both the State and other organizations have a major role in shaping different parts of social life that affect a person’s freedom. Everyone, no matter their social or economic situation, has the right to personal privacy, which ensures their intimacy and independence.[16]
• Chelameswar believed that among the fundamental rights given to individuals by the Constitution to protect them from government overreach, some rights are essential to human life itself. Therefore, they are recognized as basic, unalienable rights that are necessary for enjoying freedom. Liberty means a person’s ability to do whatever they want, and having that freedom doesn’t make sense if they don’t also have privacy.
• Bobde believed that natural rights are the rights that safeguard the moral rights that are naturally part of human life. The respect and freedom a person has over their own life are important moral values, which is why privacy is a natural and something you can’t take away. It needs to be recognized as a basic right and given constitutional safeguards, regardless of whether it is based on legal laws or common law.
• Nariman, in his concurring opinion, divided the aspects of privacy into three main areas: not interfering with a person’s body, safeguarding their personal information, and allowing them control over their personal decisions. He believed that the three major dissents by J. Fazl Ali were significant in A.K. Gopalan[17], J. Subba Rao; in Kharak Singh[18], and J. Khanna in ADM Jabalpur[19], the true meaning of Article 21 was highlighted. The dissenting opinion of J. Subba Rao in particular, it has a direct effect on privacy. It states that the right to life and personal liberty under Article 21 covers the freedom from intrusions into one’s private life. Even though the Constitution does not explicitly mention a right to privacy, it is considered a fundamental part of personal liberty.[20]
• Sapre believed that the right to privacy is a natural, unalienable, and complex right that allows a person to live a fulfilling life with dignity, and it should be acknowledged and valued in every society that follows the Rule of Law. It comes from Articles 21 and 19 along with the Preamble. This right can be limited by the state through laws, as long as those limits are reasonable and aimed at protecting important social, moral, or public interests.
• Kaul talked about the right to privacy, focusing on how personal information is protected and the right to keep one’s personal reputation intact. He mentioned that the law should include rules to protect data and also set limits on national security exceptions that let the government access data.

The decision that has been approved by all nine judges is:

1. The decision in MP Sharma[21] The decision by Satish Chandra, which claimed that the right to privacy is not protected under the Constitution of India, has been overturned.
2. The decision in Kharak Singh[22] The position of the Supreme Court of Uttar Pradesh, which holds that the right to privacy is not protected by the Constitution, is overruled.[23]
3. The right to privacy is safeguarded as a fundamental aspect of the right to life and personal freedom under Article 21 of the Indian Constitution, and it is also considered part of the freedoms outlined in Part III of the Constitution.[24]

JUDGEMENT AND RATIO DECIDENDI

Judgement: The Supreme Court of India, with all nine judges agreeing, decided on 24 August 2017 that the right to privacy is a basic right guaranteed by the Indian Constitution. The court rejected the opposing views presented in the cases of M P Sharma v. Satish Chandra[25] and Kharak Singh v. State of Uttar Pradesh[26]. The judgment explained that privacy is protected because it is a natural part of the right to life and personal freedom under Article 21, and it also comes from the freedoms listed in Part III.[27]

Ratio Decidendi: The main point of the decision is that privacy is a basic part of human dignity, autonomy, freedom, and personal liberty, and it is protected by the constitution. Although the Constitution doesn’t directly list a separate fundamental right to privacy, the rights in the Constitution should be understood in a way that protects a person’s personal life and their ability to make decisions about their own life. So, the government can’t just invade someone’s privacy whenever it wants, even if it has some kind of law or says it’s convenient. It has to follow the rules set by the constitution, which means the action must be legal, have a good reason, and not be too extreme for the situation.

The decision focused on the constitutional aspect of privacy and did not automatically settle the legality of all parts of the Aadhaar program. The next legal case about Aadhaar looked at whether the Aadhaar Act follows the rules set by the nine-judge court panel regarding privacy.

CRITICAL ANALYSIS

The main idea behind the Aadhaar program was to help the government of India deliver subsidies, benefits, and services in a more efficient, clear, and focused way, so they can work towards better governance.[28] Several people and groups questioned whether this Act is allowed by the constitution. One of the biggest problems with the Act was that it broke a basic privacy right that belongs to Indian citizens. But the Aadhaar program was one of the biggest projects ever started by the Government of India. The scheme was started with the main goal of helping the poor and less fortunate people in society. It was introduced as a program to give each person in India a special identification number. Because of this, many discussions and legal fights about privacy rights took place. The idea of dignity, people’s right to control their own information, and giving permission were the main reasons people argued for their privacy rights in the Aadhaar program.[29]

CONCLUSION

This important ruling has served as a basis for other major cases like Navtej Johar v. Union of India[30] (decriminalising Section 377)[31] and Joseph Shine v. Union of India[32] (decriminalising adultery)[33]. Although the judges reached a unanimous decision by referencing the writings of many well-known legal experts on privacy, the right to privacy, like other freedoms, isn’t completely without limits. It has certain restrictions that are meant to protect both individual and national security. These limits need to be clearly shown as necessary and reasonable for the goal they are trying to achieve. Keeping individual freedom and what society needs in check is an ongoing effort, especially as new technologies and changing social ideas keep developing. The Puttaswamy judgment not only acknowledged privacy as a basic right but also started a process where courts and lawmakers will continue to work on understanding and protecting this right in the modern world and in the future.[34] Keeping this principle in mind and using it all the time will help create the future of privacy in India.
