Show answer

Answer: (C) Article 21

In K.S. Puttaswamy v. Union of India (2017),

the Supreme Court unanimously held that Right to Privacy is a Fundamental Right under Article 21 (Right to Life and Personal Liberty).

Privacy is an intrinsic part of life and liberty.

This overruled earlier decisions (M.P. Sharma and Kharak Singh cases).

Article 15 = non-discrimination.

Article 19 = freedom of speech.

Article 29 = minority rights protection.

Answer: (c).

Why this was asked

The 2017 Puttaswamy judgment established privacy as a fundamental right under Article 21, overruling decades of previous Supreme Court decisions that had denied this protection.

This question appeared in 2021 UPSC because the Puttaswamy verdict was directly relevant to the Aadhaar debate and data protection laws being discussed in Parliament around that time.

UPSC is testing whether students know that Article 21 has been expanded by judicial interpretation beyond just physical life to include dignity, privacy, and quality of life.

Right to Privacy: Article 21 & Puttaswamy Judgment

Must know

Right to Privacy is protected under Article 21 (Right to Life and Personal Liberty)

K.S. Puttaswamy v. Union of India (2017) - landmark 9-judge bench judgment establishing privacy as fundamental right

Privacy is an intrinsic part of life and liberty - not separately enumerated but constitutionally protected

Good to know

Overruled M.P. Sharma (1954) and Kharak Singh (1963) cases that denied privacy as fundamental right

Constitutional Foundation

The Right to Privacy is not explicitly mentioned in the Constitution but has been read into Article 21 through judicial interpretation. The Supreme Court established that privacy is an intrinsic part of the right to life and personal liberty, making it a fundamental right enforceable against the state.

Question Context

This question tests knowledge of which specific Article protects privacy rights. While Articles 19, 15, and 29 protect other fundamental rights, only Article 21 has been interpreted to include privacy through the Puttaswamy judgment.

Exam traps

Trap: Article 19 seems logical since it covers freedoms, but privacy falls under life and liberty (Article 21)

Trap: Privacy is not explicitly written in any Article - it's a judicial interpretation of Article 21

Trap: Don't confuse with Article 15 (non-discrimination) or Article 29 (minority rights protection)

Trap: M.P. Sharma and Kharak Singh cases denied privacy as fundamental right - Puttaswamy overruled them
