Hmm, but the sentence here is very vague. Cos it just said that
as long as they are man and wife, its not rape. But what if its
against her will or w/o her consent? Then you will have violated
section (a) and (b). The sentence below is just to make it legal
between them to have sex w/o violating the law.
375. A man is said to commit rape who, except in the case
hereinafter excepted, has sexual intercourse with a woman under
circumstances falling under any of the 5 following
descriptions:
(a) against her will;
(b) without her consent;
(c) with her consent, when her consent has been obtained by putting
her in fear of death or hurt;
(d) with her consent, when the man knows that he is not her
husband, and her consent is given because she believes that he is
another man to whom she is or believes herself to be lawfully
married or to whom she would consent;
(e) with or without her consent, when she is under 14 years of
age.
Explanation.
Penetration is sufficient to constitute the sexual intercourse
necessary to the offence of rape.
Exception.
Sexual intercourse by a man with his own wife, the
wife not being under 13 years of age, is not rape.
