<strong>CSS</strong> <strong>152</strong> INTRODUCTION TO NIGERIA CRIMINAL LAW<br />
At common law, there is a legal presumption that an accused person is<br />
innocent until he or she is proved guilty. An <strong>of</strong>fence requires pro<strong>of</strong> <strong>of</strong> a<br />
guilty mind but if the <strong>of</strong>fence is constituted, there is a factual<br />
presumption or presumption <strong>of</strong> fact that pro<strong>of</strong> <strong>of</strong> guilty mind depends on<br />
whether the statute requires such pro<strong>of</strong> or not. In <strong>Nigeria</strong>, every <strong>of</strong>fence<br />
by whatever mode it is constituted, is a statutory <strong>of</strong>fence and must be<br />
written and therefore known to law.<br />
The mens rea doctrine was decided upon in the case <strong>of</strong> Lim Chik Aik v.<br />
R (1963) AC 160. In that case, the Judicial Committee <strong>of</strong> the Privy<br />
Council accepted the immortal words <strong>of</strong> Wright J in the <strong>of</strong>ten cited case<br />
<strong>of</strong> Sherras v. de Rutzen (1895) 1QB 918 to the effect that “there is a<br />
presumption that mens rea or evil intention or knowledge <strong>of</strong> the<br />
wrongfulness <strong>of</strong> the act is an essential ingredient in every <strong>of</strong>fence.<br />
“But that presumption is liable to be displaced either by the words <strong>of</strong> the<br />
statute creating the <strong>of</strong>fence, or by the subject matter with which it deals,<br />
and both must be considered”.<br />
But there are certain <strong>of</strong>fences in which mens rea doctrine is displaced in<br />
which case it will be said that liability is strict. It is strict because in<br />
such <strong>of</strong>fences, the law does not require the pro<strong>of</strong> <strong>of</strong> mental element or<br />
the guilty mind. The pro<strong>of</strong> <strong>of</strong> actus reus or the guilty act is enough for<br />
the conviction <strong>of</strong> the accused person.<br />
Foster Sutton, P. in Am<strong>of</strong> a v. R (1952) 14 WACA 238 said that in order<br />
to determine whether mens rea (that is to say a guilty mind or intention<br />
is essential element <strong>of</strong> the <strong>of</strong>fence charged), it is necessary to look at the<br />
object and terms <strong>of</strong> the law hat creates the <strong>of</strong>fence.<br />
b. <strong>Nigeria</strong>n Law as a Source<br />
The principle that no person should be punished without being guilty is<br />
contained in section 24 <strong>of</strong> the Criminal Code and it states that:<br />
“subject to the express provisions <strong>of</strong> this code relating to<br />
negligent acts and omissions, a person is not criminally<br />
responsible for an act or omission which occurs independently <strong>of</strong><br />
the exercise <strong>of</strong> his will or for an event which occurs by accident.”<br />
Under this category, the accused would have acted or omitted to act<br />
under a condition which is involuntary…. – i.e. independently <strong>of</strong> his/her<br />
will. This defence is separate from the defence <strong>of</strong> accident and should be<br />
treated as such. The defence comes under the generic term ‘auto<br />
