Case citation: (2019) 3 SCC 39, AIR 2018 SC 4898
Name of the Court: Supreme Court of India
Month/Year: September 2018
Brief Facts of the case:
The case revolved around the challenge to the constitutionality of Section 497 of the Indian Penal Code (IPC), a provision that criminalized adultery. According to this law, a man who had sexual relations with a married woman without the consent of her husband could be prosecuted, but the woman herself was exempt from prosecution. The provision also allowed only the husband of the married woman to file a complaint, completely ignoring the woman’s consent or agency. Joseph Shine, the petitioner, filed a public interest litigation under Article 32 of the Indian Constitution, arguing that the law was discriminatory and violated fundamental rights, including the right to equality (Article 14), the prohibition of discrimination based on sex (Article 15), and the right to life and personal liberty (Article 21). He contended that the law was archaic and rooted in patriarchal notions that treated women as the property of their husbands, depriving them of individuality and autonomy. Furthermore, the petitioner argued that adultery was a matter of personal morality and did not warrant criminalization, suggesting instead that marital issues arising from adultery should be addressed through civil remedies, such as divorce or separation, rather than criminal prosecution. The case was heard by a five judge Constitution Bench of the Supreme Court, which closely examined the provision’s compatibility with evolving constitutional principles of gender equality, individual dignity, and personal freedom.
Legal Issues[1]
- Violation of Article 14 – Right to Equality:
- Section 497 IPC treated men and women unequally by holding only men criminally liable for adultery, while women were considered victims, even if they were willing participants.
- The law did not grant women the right to prosecute their adulterous husbands, creating an imbalance in legal remedies available to spouses.
- The Supreme Court had to determine whether this gender-based distinction was justified under the Constitution.
- Violation of Article 15 – Prohibition of Discrimination:
- Article 15(1) prohibits discrimination on the basis of sex. Section 497 was based on outdated gender stereotypes that viewed women as passive participants in adultery and as the property of their husbands.
- The Court had to examine whether this classification was constitutionally valid or if it reinforced patriarchal notions contrary to gender justice.
- Violation of Article 21 – Right to Life and Personal Liberty:
- Criminalizing adultery was argued to interfere with an individual’s right to privacy, personal liberty, and autonomy.
- The law allowed a husband to have control over his wife’s fidelity, treating her as lacking agency.
- The Court had to decide whether the right to dignity and personal choice in relationships was being infringed by this law.
- Arbitrariness and Lack of Rational Nexus:
- The doctrine of arbitrariness states that laws must have a rational nexus to their objectives.
- Section 497 IPC criminalized adultery only when a married woman was involved, and only if it occurred without the husband’s consent. This implied that the husband’s consent could legitimize extramarital relationships, making the provision arbitrary.
- The Court had to assess whether this arbitrary distinction failed the test of reasonable classification under Article 14.
- Adultery as a Criminal vs. Civil Issue:
- In a modern legal framework, the criminal law is meant to address offenses against the State, while adultery is primarily a private issue between spouses.
- The Supreme Court had to decide whether criminalizing adultery served any legitimate public purpose or if it should be treated solely as a ground for divorce under civil laws.
- Impact on Marital Autonomy and Individual Rights:
- The law treated marriage as an institution where a husband exercised control over his wife’s choices.
- The Court had to determine whether such a provision was in line with the principles of equality, personal liberty, and dignity in a democratic society.
Judgement
The Supreme Court of India, in a historic and unanimous judgment on September 27, 2018, declared Section 497 of the Indian Penal Code (IPC) unconstitutional, striking down the 158-year-old provision that criminalized adultery[2]. The five-judge Constitution Bench, led by Chief Justice Dipak Misra and comprising Justices R.F. Nariman, A.M. Khanwilkar, D.Y. Chandrachud, and Indu Malhotra, held that the law was arbitrary, outdated, and violative of fundamental rights, particularly Articles 14, 15, and 21 of the Indian Constitution. The Court observed that Section 497 was rooted in patriarchal notions, treating women as mere property of their husbands rather than as independent individuals with equal rights. The law penalized only men for engaging in adultery while exempting women, thereby creating a gender-based discrimination that failed the test of equality under Article 14. Furthermore, the judgment emphasized that Article 15, which prohibits discrimination based on sex, was violated as the law was based on outdated stereotypes that denied women agency in their marital relationships. Additionally, Article 21, which guarantees the right to life and personal liberty, was infringed as the provision undermined an individual’s right to privacy, dignity, and autonomy by criminalizing a private act between consenting adults. The Court held that marriage does not mean the loss of autonomy for either spouse and that personal choices in intimate relationships should not be subject to criminal law. The Bench ruled that adultery, while morally wrong, should not be a criminal offense but rather a civil matter that could serve as grounds for divorce. Justice D.Y. Chandrachud, in his separate but concurring opinion, highlighted that the state should not interfere in the personal affairs of individuals and that punishing adultery disproportionately burdened men while infantilizing women, denying them equal rights in marriage. Justice Indu Malhotra also noted that criminal law should not be used to enforce morality or regulate private relationships. The verdict marked a significant milestone in India’s legal and social history, reinforcing gender equality, personal liberty, and the progressive interpretation of fundamental rights. The decision was widely regarded as a step forward in dismantling archaic laws that no longer aligned with the principles of the Indian Constitution.
Impact of the case
The Supreme Court’s decision to strike down Section 497 of the IPC had a far-reaching impact on India’s legal and social landscape. The judgment was a major step toward gender equality, personal liberty, and individual autonomy. Below are some key impacts of the ruling:
- Advancement of Gender Equality
The verdict reaffirmed the constitutional principle of equality (Article 14) by ensuring that women were no longer treated as the property of their husbands. It eliminated a law that punished only men for adultery while treating women as passive participants, thereby removing gender-based discrimination in the legal framework.
- Strengthening of Individual Autonomy and Privacy
The Court emphasized that personal relationships and choices in marriage are a private matter and should not be regulated by criminal law. By citing Article 21 (Right to Life and Personal Liberty), the ruling reinforced the right to privacy, dignity, and autonomy in personal relationships.
- Decriminalization of Morality-Based Laws
The judgment set a precedent against criminalizing personal choices based on outdated moral standards. The Court acknowledged that adultery, though a ground for divorce, should not be a criminal offense as it does not harm society at large. This principle could influence future legal reforms in India regarding morality-based laws.
- Marriage and Family Laws Remain Intact
While adultery was decriminalized, the Supreme Court clarified that it could still be used as a ground for divorce under personal laws. This ensured that spouses could seek legal recourse in cases of infidelity without resorting to criminal prosecution.
- Shift in the Role of the State in Personal Matters
The ruling marked a shift in the state’s role in regulating personal relationships. It emphasized that laws should not interfere in private affairs unless they cause actual harm to society. This could have implications for future legal challenges to laws that interfere with personal freedoms.
- Influence on Other Legal Reforms
The judgment set a progressive legal precedent, influencing discussions on other laws that impact women’s rights, marriage, and personal freedom. It reinforced the idea that laws should be gender-neutral and uphold constitutional principles rather than outdated social norms.
- Public and Societal Reactions
The verdict received mixed reactions. While legal experts, women’s rights activists, and progressives welcomed it as a step toward gender justice, some traditional and conservative groups opposed it, arguing that it might weaken the institution of marriage. However, over time, the ruling has been seen as a progressive step toward modernizing India’s legal system.
Conclusion
This case marked a transformative moment in India’s legal history. By decriminalizing adultery, the Supreme Court upheld individual liberty, gender equality, and personal autonomy. The judgment recognized that marriage is based on trust, not legal enforcement through criminal laws. It aligned Indian jurisprudence with modern progressive values, emphasizing dignity and freedom of choice. This ruling not only safeguarded constitutional rights but also reinforced the evolving nature of societal norms, ensuring that personal relationships remain a matter of personal conscience rather than state intervention.
