Chapter XVI, Section 377 of the Indian Penal Code is a legislation in India used to criminalise homosexual activity.This was introduced during British rule in india.
Unnatural sexual offenses: Whoever voluntarily has carnal intercourse against the order of nature with any man, woman or animal shall be punished with imprisonment which may extend to ten years, and shall also be liable to fine.
- Explanation: Penetration is sufficient to constitute the carnal intercourse necessary to the offense described in this section.
Because this section bans “carnal intercourse against the order of nature with any man, woman or animal”, treating them as criminals, it has been criticized by groups supporting gay rights.
The movement to repeal Section 377 has been led by the Naz Foundation India Trust, an activist group and is currently under a constitutional challenge at the Delhi High Court
