50. Joseph Shine v. Union of India
The Case That Decriminalised Adultery and Reaffirmed Equality, Privacy and Individual Autonomy
Citation
Joseph Shine v. Union of India
[2018] 11 SCR 765
(2019) 3 SCC 39
AIR 2018 SC 4898
Bench Strength: 5 Judges, Constitution Bench
Decision: Unanimous
Judgment Delivered: 27 September 2018
The Supreme Court struck down Section 497 of the Indian Penal Code, 1860 and the corresponding procedural provision under Section 198 of the Code of Criminal Procedure, 1973.
Background
Section 497 IPC made adultery a criminal offence.
But the provision did not treat men and women equally.
Under the statutory scheme, a man could be prosecuted for having s*xual in*******se with a married woman without the consent or connivance of her husband.
The woman herself could not be punished as an abettor.
More fundamentally, the law treated the husband as the person whose consent mattered.
The wife was effectively placed within a legal framework that treated her s*xual autonomy as subordinate to her husband’s authority.
Section 198 CrPC complemented Section 497 by determining who could initiate a prosecution for adultery.
The constitutional challenge therefore raised a much deeper question than whether adultery should be criminalised:
Can the State enforce a criminal law founded upon an unequal and patriarchal conception of marriage?
Issues Before the Court
The Constitution Bench considered:
1. Whether Section 497 IPC violated Articles 14, 15 and 21?
2. Whether the provision discriminated against women on the basis of s*x?
3. Whether treating the husband as the legally aggrieved person violated women’s dignity and autonomy?
4. Whether criminalising adultery amounted to an unconstitutional intrusion into the privacy of marriage?
5. Whether Section 198 CrPC, which governed prosecution for adultery, was constitutionally valid?
6. Whether adultery could legitimately remain a criminal offence when it could continue to operate as a civil ground for divorce?
Arguments
Petitioner’s Arguments
The petitioner argued that Section 497:
* Created an unconstitutional gender distinction.
* Treated women as subordinate to their husbands.
* Denied women equal s*xual and personal autonomy.
* Violated Articles 14, 15 and 21.
* Permitted the State to intrude excessively into the private sphere of marriage.
* Was based upon outdated patriarchal assumptions.
Union of India’s Position
The Union defended the provision primarily on the basis that criminalisation of adultery served to protect the sanctity and stability of marriage.
The constitutional question was therefore whether preserving marital stability could justify a criminal law that itself operated through gender inequality and intrusion into individual autonomy.
Judgment
The Supreme Court unanimously held that adultery should not be treated as a criminal offence.
It struck down Section 497 IPC as unconstitutional and also invalidated Section 198 CrPC insofar as it dealt with prosecution for the offence of adultery.
The Court overruled earlier decisions including Sowmithri Vishnu v. Union of India and V. Revathi v. Union of India, which had upheld the constitutional validity of the adultery regime.
The judgment did not declare adultery morally acceptable or abolish its consequences in matrimonial law.
Adultery could continue to have civil consequences, including serving as a ground for divorce under applicable matrimonial law.
The critical distinction was:
A wrong in a marriage does not automatically have to become a crime against the State.
Major Holdings
1. Section 497 Violated Article 14
The provision created an irrational and discriminatory classification.
It treated the husband as the person whose consent could determine whether an offence existed.
The wife had no equivalent legal authority.
The Court found the provision manifestly arbitrary and inconsistent with constitutional equality.
2. The Law Was Based on Patriarchal Assumptions
Section 497 effectively proceeded on the assumption that a wife was subject to her husband’s control.
The Court rejected this conception.
A constitutional democracy cannot treat a woman as the property or subordinate of her husband.
3. Women’s Dignity and Autonomy Matter
The Court connected equality with individual dignity and autonomy.
Women cannot be constitutionally treated as passive subjects whose choices are controlled by husbands or by paternalistic State legislation.
4. Adultery Falls Within the Sphere of Privacy
The Court recognised the intensely private nature of matrimonial relationships.
Turning adultery into a criminal offence enabled the State to intrude deeply into the intimate sphere of marriage.
Such criminalisation was not constitutionally justified.
5. Adultery Is Not Necessarily a Crime
The Court made an important distinction between:
Moral wrong
and
criminal wrong.
A person’s conduct may be morally objectionable or may provide a basis for civil consequences without necessarily justifying imprisonment or criminal punishment.
The Five Principles Laid Down
1. Marriage Does Not Destroy Individual Autonomy
Marriage does not transfer an individual’s constitutional identity or liberty to the spouse.
2. Women Are Equal Constitutional Citizens
The law cannot treat a wife as subordinate to her husband.
3. Privacy Protects the Intimate Sphere
The State must have compelling constitutional justification before entering deeply into private relationships.
4. Morality Alone Cannot Justify Criminalisation
Not every moral wrong should become a criminal offence.
5. Constitutional Morality Rejects Patriarchy
Traditional social assumptions cannot override equality, dignity and individual autonomy.
Constitutional Provisions
Article 14
Equality Before Law
Section 497 created an irrational and discriminatory legal framework based on gender and marital status.
Article 15(1)
Prohibition of Discrimination
The provision reflected discriminatory gender stereotypes and unequal treatment.
Article 21
Life, Personal Liberty, Dignity and Privacy
Criminalisation of adultery interfered with individual dignity, autonomy and the privacy of intimate relationships.
Ratio Decidendi
Section 497 IPC is unconstitutional because it violates Articles 14, 15(1) and 21 by treating women as subordinate to their husbands, denying equal autonomy and dignity, and permitting excessive State intrusion into the private sphere of marriage. Adultery may have civil consequences, but it cannot constitutionally be treated as a criminal offence on the basis of the patriarchal assumptions embedded in Section 497.
Why Section 497 Was Particularly Problematic
The structure of the offence revealed its underlying assumption.
A husband could effectively consent to another man having s*xual relations with his wife, and that consent could prevent the offence from arising.
The wife, however, had no corresponding power.
This led the Court to identify the deeper problem:
The law was not simply regulating adultery. It was regulating the husband’s proprietary interest in his wife.
That conception was incompatible with constitutional equality and dignity.
Joseph Shine and Transformative Constitutionalism
The judgment fits into the Supreme Court’s broader movement toward transformative constitutionalism.
The Court rejected the idea that historical existence alone can justify a law.
A provision may have existed for decades and still be unconstitutional.
Constitutional interpretation must respond to contemporary understandings of:
Equality
Dignity
Privacy
Autonomy
Individual liberty
The Court expressly treated the criminalisation of adultery as inconsistent with this constitutional transformation.
Key Precedents
Sowmithri Vishnu v. Union of India
Earlier upheld the constitutional validity of Section 497.
Overruled in Joseph Shine.
V. Revathi v. Union of India
Previously upheld the procedural framework surrounding prosecution for adultery.
Overruled in Joseph Shine.
Justice K.S. Puttaswamy v. Union of India (2017)
Recognised privacy as a Fundamental Right and strengthened the constitutional protection of personal autonomy.
Navtej Singh Johar v. Union of India (2018)
Reaffirmed dignity, autonomy, equality and constitutional morality in the context of intimate personal choices.
Shayara Bano v. Union of India (2017)
Strengthened constitutional scrutiny of practices rooted in discriminatory or arbitrary structures.
Why It Matters
Joseph Shine is not a judgment about encouraging adultery.
It is a judgment about the limits of criminal law.
The State cannot convert every moral or relational wrong into a crime.
More importantly, it cannot criminalise conduct through a legal framework founded on the assumption that:
a husband owns his wife’s s*xuality.
The constitutional transformation is therefore profound:
From ownership to autonomy.
From patriarchy to equality.
From morality imposed by the State to individual constitutional liberty.
Examination Takeaway
Rule to Remember
Section 497 IPC criminalising adultery was struck down as unconstitutional for violating Articles 14, 15(1) and 21. Marriage does not extinguish individual autonomy, and adultery may remain a civil or matrimonial wrong without being a criminal offence.
One-Line Memory Formula
Joseph Shine (2018): Adultery may be a matrimonial wrong, but it is not a crime; marriage does not destroy equality, dignity, privacy or individual autonomy.
