Joseph Shine v. Union of India

The story

For nearly 158 years, Section 497 of the Indian Penal Code let a husband prosecute his wife's lover for adultery — but never his wife, and never himself if the roles were reversed. Joseph Shine, troubled by a friend's suicide after a false adultery accusation, took the fight to the Supreme Court, arguing the law was a relic that reduced married women to their husbands' possessions. The stakes were high: not just one man's grievance, but the dignity and autonomy of millions of women silenced by a law that assumed they had no sexual agency of their own. In September 2018, a five-judge bench led by then Chief Justice Dipak Misra delivered a resounding verdict, unanimously striking down Section 497. Justice D.Y. Chandrachud wrote powerfully about marital rape-like control embedded in the old law and how the Constitution demands recognition of women as equal, autonomous beings — not chattel. The human moment came in the Court's blunt acknowledgment: fidelity is a matter of personal conscience and civil consequence, not criminal punishment. Adultery remained a valid ground for divorce, but the threat of jail vanished. It was a quiet revolution — one that finally let the law catch up with the idea that marriage is a partnership of equals, not ownership.

The facts

Joseph Shine, a non-resident Keralite, filed a PIL challenging the constitutional validity of Section 497 of the Indian Penal Code, which criminalized adultery. The provision punished a man who had consensual sexual intercourse with a married woman without her husband's consent, but did not permit prosecution of the wife even as an abettor, and gave no similar right to a wife against her husband's infidelity. The law was challenged as archaic, patriarchal, and discriminatory, treating women as the property of their husbands.

The question before the court

Whether Section 497 IPC, read with Section 198(2) CrPC, violates Articles 14, 15 and 21 of the Constitution by discriminating on the basis of sex and denying women agency and equal treatment in matters of marital fidelity.

The holding

A five-judge Constitution Bench unanimously struck down Section 497 IPC and the corresponding procedural provision in Section 198(2) CrPC as unconstitutional, holding that the law was manifestly arbitrary, discriminatory against women, and violative of Articles 14, 15 and 21 of the Constitution. The Court held that adultery, while it may be a ground for civil remedies such as divorce, cannot be treated as a criminal offence, since the provision was founded on outdated notions of a husband's proprietary control over his wife's sexuality and denied women equal agency and dignity.

The principle it stands for

A penal law that singles out one sex for punishment, denies women equal agency and standing, and is grounded in the notion of a spouse as property rather than an autonomous individual, offends the guarantees of equality (Article 14), non-discrimination on the ground of sex (Article 15), and the right to privacy, dignity and autonomy (Article 21). Criminal law cannot be used to enforce personal fidelity within marriage where doing so entrenches gender stereotypes and denies individual autonomy.
