(1)Nothing is an offence which is done by a person who, at the time of doing it, by reason of unsoundness of mind, is —

(a)incapable of knowing the nature of the act;

(b)incapable of knowing that what he is doing is wrong; or

(c)completely deprived of any power to control his actions.

(2)Subsection (1)(b) applies only if the person is incapable of knowing that his act —

(a)is wrong by the ordinary standards of reasonable and honest persons; and

(b)is wrong as contrary to law.

Illustration

A, while labouring under a delusion, believes that he has received divine instructions to kill Z and that it is morally right for him to do so. A however knows that it is contrary to law to kill Z. A kills Z. Here, the defence of unsoundness of mind is not available to A as he is capable of knowing that it is contrary to law to kill Z.
