Delhi HC Acquits Man in Adultery Case: Section 497 IPC Invalid Retrospectively
Court applies Joseph Shine ruling to past convictions
Equality and liberty reaffirmed in landmark decision
By Legal Reporter
New Delhi: May 15, 2026:
The Delhi High Court has acquitted a man convicted under Section 497 IPC (adultery), ruling that the provision—struck down by the Supreme Court in Joseph Shine v. Union of India (2018)—is unconstitutional with retrospective effect. This judgment confirms that pending or past convictions under Section 497 cannot survive, reinforcing constitutional guarantees of equality and personal liberty.
Background
Section 497 of the Indian Penal Code criminalized adultery, punishing only the man who engaged in sexual relations with another man’s wife without the husband’s consent. The wife herself was not punishable, reflecting a patriarchal notion of women as property. This provision was long criticized as discriminatory and violative of fundamental rights.
In Joseph Shine v. Union of India (2018), a Constitution Bench of the Supreme Court unanimously struck down Section 497 IPC, holding it unconstitutional for violating Articles 14 (equality), 15 (non-discrimination), and 21 (personal liberty). The Court emphasized that autonomy and dignity of women cannot be compromised by archaic laws.
The Delhi High Court Case
In the present matter, a man had been convicted under Section 497 IPC based on allegations of an adulterous relationship. Justice Vimal Kumar Yadav of the Delhi High Court acquitted him, noting that once the Supreme Court declared Section 497 unconstitutional, it ceased to exist in law. Therefore, convictions or pending cases under this provision cannot be sustained.
The Court also drew an analogy with the ancient practice of “Niyog Pratha” from the Mahabharata, where lineage continuation arrangements reflected patriarchal control over women. The judge remarked that Section 497 was a “modern avatar” of such outdated practices, underscoring its incompatibility with constitutional values.
Key Legal Principles
- Retrospective Effect of Constitutional Invalidity:
The Court relied on precedents such as Maj. Gen. A.S. Gauraya v. S.N. Thakur (1986), which held that when a law is declared unconstitutional, it is void ab initio and cannot be enforced even in pending cases. Thus, Section 497 IPC is deemed never to have existed in valid law. - Equality Before Law (Article 14):
Section 497 punished only men, excluding women, thereby creating gender-based discrimination. - Non-Discrimination (Article 15):
The law treated women as passive subjects, denying them agency and reinforcing patriarchal norms. - Right to Privacy and Personal Liberty (Article 21):
Criminalizing consensual adult relationships intruded upon individual autonomy and dignity.
Judicial Observations
The Court highlighted that marriage does not extinguish individual autonomy, and consensual relationships cannot be criminalized. It also criticized the archaic notion of treating wives as property of husbands, a concept incompatible with modern constitutional morality.
Broader Implications
- Final Closure of Adultery Prosecutions:
All pending cases under Section 497 IPC must be quashed, ensuring no one remains convicted under an unconstitutional law. - Strengthening Women’s Rights:
The ruling reinforces women’s autonomy, rejecting patriarchal control embedded in outdated statutes. - Legal Clarity:
The judgment provides certainty that the Joseph Shine ruling applies retrospectively, preventing misuse of Section 497 in any form.
