Section 377 IPC: Unnatural Offences under Indian Penal Code 1860
Section 377 of the Indian Penal Code, 1860 dealt with what the statute described as "unnatural offences." Its original wording was broad, but the constitutional scope of the provision was substantially restricted by the Supreme Court in Navtej Singh Johar v. Union of India in 2018. This article explains Section 377 as it stood in law immediately before the Bharatiya Nyaya Sanhita, 2023 came into force.
- The statutory provision dealt with voluntary carnal intercourse described as being "against the order of nature" with a man, woman or animal.
- The statutory punishment was imprisonment for life, or imprisonment of either description for a term which could extend to ten years, and fine.
- Penetration was sufficient for the carnal intercourse required by the statutory explanation.
- From 6 September 2018, consensual sexual conduct between competent adults in private was outside the enforceable scope of Section 377.
What did Section 377 IPC provide?
The statutory text of Section 377 criminalised specified voluntary carnal intercourse with a man, woman or animal and prescribed imprisonment for life or imprisonment up to ten years, together with fine. Its explanation stated that penetration was sufficient to constitute the carnal intercourse necessary for the offence.
Essential statutory components
Voluntary act: The section used the expression "voluntarily has carnal intercourse."
Nature of intercourse: The statute used the expression "against the order of nature."
Person or animal: The statutory wording referred to intercourse with any man, woman or animal.
Penetration: The explanation provided that penetration was sufficient to constitute the carnal intercourse required by the section.
Punishment under Section 377 IPC
| Provision | Punishment stated in Section 377 IPC |
|---|---|
| Section 377 | Imprisonment for life, or imprisonment of either description for a term which may extend to ten years, and liability to fine. |
The reference to "imprisonment for life" replaced the earlier expression "transportation for life" through Act 26 of 1955, with effect from 1 January 1956.
Effect of Navtej Singh Johar on Section 377
Accordingly, immediately before commencement of the Bharatiya Nyaya Sanhita, the bare wording of Section 377 could not be read in isolation. Its operation had to be understood subject to the constitutional ruling in Navtej Singh Johar.
What was no longer an offence under Section 377 after 2018?
Consensual sexual acts between competent adults in private could not be criminalised under Section 377 merely because the conduct fell within the expressions used in the original statutory text. The Supreme Court's ruling applied irrespective of the sex or sexual orientation of the consenting adults.
What remained within the scope of Section 377?
The Supreme Court did not invalidate Section 377 in its entirety. The provision continued to have legal operation outside the protected sphere of consensual sexual conduct between competent adults. In particular, its remaining field included non-consensual sexual acts falling within the provision and sexual acts involving animals.
Meaning of consent in the post-Navtej context
The constitutional protection recognised in Navtej Singh Johar concerned consensual sexual conduct between competent adults in private. It did not create immunity for conduct lacking consent, involving a person legally incapable of giving valid consent, or involving an animal. Depending on the facts, other provisions of the IPC or special criminal laws could also apply.
Section 377 and other sexual-offence provisions
Section 377 operated alongside other IPC provisions concerning sexual offences. For example, Section 375 IPC defined rape and Section 376 IPC prescribed punishment for rape. The applicable offence depended on the nature of the act, the victim, consent, age, and other circumstances.
Section 377 and offences involving children
Where a child was involved, the Protection of Children from Sexual Offences Act, 2012 could apply according to the facts. The POCSO Act is a special statute dealing with sexual offences against persons below eighteen years of age. The constitutional protection recognised for consensual conduct between competent adults did not extend to sexual conduct with children.
Position immediately before Bharatiya Nyaya Sanhita 2023
Immediately before the new criminal laws came into force on 1 July 2024, Section 377 remained part of the IPC but had to be applied subject to the binding constitutional limitation imposed in Navtej Singh Johar. Therefore, describing all conduct covered by the literal wording of the old section as criminal would be legally inaccurate for the post-2018 period.
Historical statutory text and current interpretation
The original page reproduced the bare statutory wording of Section 377. That wording remains important for understanding the historical provision, but for the period from 6 September 2018 until the IPC was replaced by the new criminal-law framework, the statutory text must be read together with the Supreme Court's constitutional ruling.
Note: This page explains the IPC position before commencement of the Bharatiya Nyaya Sanhita, 2023. The law applicable to a particular case depends on the date of the alleged act, the facts, the age and capacity of the persons concerned, consent, and any applicable special statute.
