The Right to Privacy was declared a fundamental right under Article 21 by the Supreme Court in Justice K.S. Puttaswamy v. Union of India (2017), marking a turning point in protecting individual dignity, autonomy, and freedom in the digital age.
📚 Introduction
For decades, India did not explicitly recognize a right to privacy. That changed dramatically in 2017, when a nine-judge bench of the Supreme Court unanimously ruled that privacy is a fundamental right.
In a world of surveillance, data leaks, facial recognition, and social media tracking, this judgment came as a constitutional shield for every Indian citizen.
🧾 Constitutional Basis
The Right to Privacy is not specifically mentioned in the Constitution. But the Supreme Court held that it is implicit in:
-
Article 21 – Right to life and personal liberty
-
Article 19 – Freedom of expression and movement
-
Article 14 – Right to equality and dignity
Privacy is essential for exercising these rights meaningfully. Whether it’s about how we live, who we love, what we browse, or how we vote—privacy protects it all.
⚖️ Landmark Case: Justice K.S. Puttaswamy v. Union of India (2017)
-
Retired judge K.S. Puttaswamy challenged the mandatory Aadhaar linkage, arguing it violated privacy.
-

✅ The Court overruled both and declared:
“Privacy is intrinsic to life and liberty under Article 21.”
The judgment emphasized:
-
Dignity
-
Autonomy
-
Freedom of thought

Bodily integrity

This keeps a balance between individual rights and national interest.
