Here is the recent judgment by the SC on rape.
An excerpt :
“What constitutes an outrage to female modesty is nowhere defined in IPC. The essence of a woman’s modesty is her sex. The culpable intention of the accused is the crux of the matter. The reaction of the woman is very relevant, but its absence is not always decisive. Modesty in this Section is an attribute associated with female human beings as a class. It is a virtue which attaches to a female owing to her sex. The act of pulling a woman, removing her saree, coupled with a request for sexual intercourse, is such as would be an outrage to the modesty of a woman; and knowledge, that modesty is likely to be outraged, is sufficient to constitute the offence without any deliberate intention having such outrage alone for its object. As indicated above, the word ‘modesty’ is not defined in IPC.”
