" No person shall be deprived of his life or personal liberty except according to the procedure established by law."

Article 21 of the Indian Constitution guarantees the fundamental right to life and personal liberty to every individual. It is one of the most crucial and widely interpreted provisions in Indian jurisprudence. This article not only protects the physical existence of citizens but also encompasses a broader understanding of life, including dignity, privacy, and basic human rights. Over the years, Article 21 has evolved through judicial interpretation to encompass various aspects such as environmental protection, right to education, healthcare, and a fair trial, making it a cornerstone of India's constitutional framework.

Historical Context
During British rule, India faced significant challenges related to civil liberties and human rights. The colonial administration often used arbitrary detention, censorship, and repressive measures to suppress dissent and control the population. Indian freedom fighters and leaders, such as Mahatma Gandhi, Jawaharlal Nehru, and Dr. B.R. Ambedkar, emphasized the importance of individual rights and freedoms in a democratic society.

After India gained independence in 1947, the Constituent Assembly was tasked with drafting the Constitution. The debates in the Constituent Assembly reflected diverse viewpoints on the scope and nature of fundamental rights. Several members, including Dr. B.R. Ambedkar, emphasized the need to protect fundamental rights as essential pillars of democracy. The debates also highlighted the influence of international human rights principles and legal frameworks on the drafting of India's Constitution.

The framers of the Indian Constitution recognized the importance of enshrining fundamental rights to safeguard individual liberties and prevent abuse of state power. The Fundamental Rights chapter, including Article 21, was inspired by the Universal Declaration of Human Rights and other international treaties. Article 21 was specifically included to guarantee the right to life and personal liberty, reflecting the values of justice, equality, and dignity.

Since its enactment, Article 21 has undergone significant interpretation and evolution through judicial pronouncements. The Supreme Court of India has expanded the scope of Article 21 to include a wide range of rights, such as the right to privacy, right to health, right to clean environment, right to livelihood, and right to education. Landmark judgments, including Maneka Gandhi v. Union of India and K.S. Puttaswamy v. Union of India, have shaped the understanding and application of Article 21 in contemporary legal discourse.

Article 21 has had a profound impact on Indian society by empowering individuals to challenge arbitrary state action, seek justice, and assert their rights. It has served as a safeguard against human rights violations, ensuring accountability and transparency in governance. The ongoing interpretation and enforcement of Article 21 continue to shape India's legal framework and contribute to the protection of fundamental freedoms.

The historical background of Article 21 reflects India's journey towards independence, the aspirations for a democratic republic based on the rule of law, and the enduring commitment to protect and uphold fundamental rights.

Right to Privacy
The right to privacy under Article 21 of the Indian Constitution has been a subject of significant legal debate and judicial interpretation. The explicit recognition of the right to privacy as a fundamental right under Article 21 came through a series of landmark judgments by the Supreme Court of India. The case of K.S. Puttaswamy v. Union of India (2017), commonly known as the Aadhaar judgment, marked a pivotal moment where the Supreme Court affirmed that privacy is an integral part of the right to life and personal liberty guaranteed by Article 21.

The Supreme Court's decision in the Puttaswamy case emphasized that privacy is essential for safeguarding individual autonomy, dignity, and personal choices. It recognized privacy as a core value that underpins other fundamental rights, such as freedom of speech, expression, and association.

The right to privacy under Article 21 encompasses various facets, including informational privacy, bodily integrity, spatial privacy, and decisional autonomy. It protects individuals from unwarranted intrusion by the state or private entities into their private lives, communications, personal data, and bodily autonomy. While affirming the right to privacy, the Supreme Court has also recognized that the state may impose reasonable restrictions on privacy rights in the interest of national security, public order, morality, and other legitimate concerns.

The principle of proportionality is often applied to assess the validity of such restrictions and ensure that they are necessary and proportionate to achieve a legitimate aim. The recognition of privacy as a fundamental right has significant implications for data protection laws, surveillance practices, and the use of technology. It has led to discussions and legislative initiatives, such as the Personal Data Protection Bill, aimed at protecting individuals' privacy rights in the digital age.

The Supreme Court's pronouncements on privacy rights under Article 21 have set important precedents for future cases involving privacy violations. Subsequent judgments have built upon the Puttaswamy case, refining the understanding of privacy in various contexts, including surveillance, social media, healthcare, and reproductive rights.

The right to privacy under Article 21 of the Indian Constitution is a vital aspect of individual freedom and dignity. Its recognition and protection by the judiciary have contributed to shaping India's legal landscape and ensuring that privacy rights are upheld in the face of evolving societal challenges and technological advancements.
