Navtej Singh Johar Case (2018) – Decriminalisation of Homosexuality

Section 377 decriminalised is how the Supreme Court's 2018 ruling in Navtej Singh Johar v. Union of India is best remembered — the judgment that struck down the colonial-era provision criminalising consensual sexual acts between adults of the same sex. It stands today as one of the defining Article 21 judgments on dignity, privacy and non-discrimination.

What the case was about

Section 377 of the Indian Penal Code criminalised "carnal intercourse against the order of nature," a provision historically used to prosecute consensual homosexual conduct between adults. In Navtej Singh Johar v. Union of India (2018), the Supreme Court examined whether this provision, insofar as it criminalised consensual sexual acts between adults of the same sex, was constitutionally valid.

The Court's ruling

The Supreme Court partly struck down Section 377, holding that the provision is unconstitutional to the extent it criminalises consensual sexual acts between adults of the same sex. The Court found that this part of the provision violated several fundamental rights together:

• Article 14 — the right to equality, since the provision arbitrarily and unreasonably targeted a class of citizens based on their sexual orientation.
• Article 15 — the right against discrimination, extended to cover discrimination on the ground of sexual orientation.
• Article 19(1)(a) — the right to freedom of expression, which the Court held includes the freedom to express one's sexual identity.
• Article 21 — the right to live a life of dignity and privacy, core aspects of which had already been recognised in the Court's 2017 privacy judgment.

The Court held that members of the LGBT (lesbian, gay, bisexual and transgender) community are entitled to the same fundamental rights as any other citizen, and that criminalising private, consensual conduct between adults on the basis of sexual orientation could not be reconciled with the Constitution's guarantees of equality, dignity and privacy.

The link to the right to privacy judgment

The reasoning in Navtej Singh Johar built directly on the Supreme Court's earlier decision in K.S. Puttaswamy v. Union of India (2017), which recognised the right to privacy as a fundamental right forming part of Article 21, subject to reasonable restrictions tested against standards of legality, need and proportionality. The Puttaswamy judgment's treatment of privacy and personal autonomy went on to influence several subsequent rulings, including the case on entry of women into the Sabarimala temple, the case decriminalising adultery, and Navtej Singh Johar itself — all decided in 2018.

Part of the wider Article 21 story

Navtej Singh Johar fits within the Supreme Court's long-running practice, beginning with Maneka Gandhi v. Union of India (1978), of reading Article 21's guarantee of "life" and "personal liberty" expansively to include dignity, privacy and autonomy — rather than confining it to the narrow, purely physical sense used in the Constitution's early years. Each addition to this list, from the right to livelihood to the right to privacy, has widened the practical reach of the fundamental rights chapter.

UPSC Relevance

Prelims: Know that Navtej Singh Johar (2018) partly struck down Section 377 IPC; the articles invoked were 14, 15, 19 and 21; and the case built on the 2017 Puttaswamy privacy judgment.

Mains: Useful for GS2 answers on judicial protection of dignity and privacy, the evolving interpretation of Article 21, and the relationship between constitutional morality and social change. Can also be cited alongside the Puttaswamy and Joseph Shine (adultery) judgments as part of the 2017–2018 cluster of rulings expanding personal liberty and autonomy.

FAQ

Q1. What did the Navtej Singh Johar case decide? It held Section 377 of the Indian Penal Code unconstitutional to the extent it criminalised consensual sexual acts between adults of the same sex.

Q2. Which fundamental rights were held to be violated? Articles 14 (equality), 15 (non-discrimination), 19(1)(a) (freedom of expression) and 21 (dignity and privacy).

Q3. How is this case connected to the right to privacy judgment? The 2017 Puttaswamy judgment recognised privacy as part of Article 21; this reasoning directly supported the Court's finding in Navtej Singh Johar that criminalising private, consensual conduct violated dignity and privacy.

Q4. Did the judgment strike down Section 377 entirely? No — only to the extent that it criminalised consensual sexual acts between adults of the same sex; the provision otherwise continues to apply, for instance to non-consensual acts.
