State of UP Vs Babul Nath (1994) 6 SCC 29 Supreme Court

Hon’ble Supreme Court of India observed as under

"To constitute the offence of rape neither Section 375 of IPC nor the Explanation attached thereto require that there should necessarily be complete penetration of the penis into the private part of the victim/prosecutrix. In other words to constitute the offence of rape it is not at all necessary that there should be complete penetration of the male organ with emission of semen and rupture of hymen. Even partial or slightest penetration of the male organ within the labia majora or the vulva or pudenda with or without any emission of semen or even an attempt at penetration into the private part of the victim would be quite enough for the purpose of Sections 375 and 376 of IPC. That being so it is quite possible to commit legally the offence of rape even without causing any injury to the genitals or leaving any seminal stains. But in the present case before us as noticed above there is more than enough evidence positively showing that there was sexual activity on the victim and she was subjected to sexual assault without which she would not have sustained injuries of the nature found on her private part by the doctor who examined her."
