Voluntary / Self induce intoxication is not define in the Penal Code
It involves deliberate or intentional consumption of drinks or drugs to an amount that can produce a state of intoxication
The law of intoxication laid down in Beard (1920) states that:-
Facts: Arthur Beard was indicated for murder having ravished a 13 year old girl and in furtherance of the act of rape placed his hand upon her mouth and his thumb open her throat hereby causing death by suffocation. The defence was drunkenness. On the facts there was no evidence that he was too drunk to from the intention of committing rape
The House of Lords (HOL) ruled that:-
1. Insanity whether produces by drunkenness or otherwise is a defence to the crime charged
2. Evidence of drunkenness which renders the accused incapable of forming the specific intent essential to constitute the crime should be taken into consideration with the other facts proved in order to determine whether or not he had this intent.
3. Evidence of drunkenness failing short of a proved incapacity in the accused to form the intent necessary to constitute the crime and merely est. that his mind was affected by drink so that he more readily gave away to some violent passion does not rebut the presumption that a man intends the natural consequences of his acts.
Distinction between insanity produce by intoxication [S85(2)(b)] and unsoundness of mind [S84] is made under Penal Code.
However noted that drafting in Section 85 (2)(b) used is insane and not unsoundness of mind.
Under McNaghten Rules no distinction is drawn between insanity arising from intoxication or other causes so long as it result in a disease of the mind
Lord Birkenhead in Beard (1920) said “insanity” whether produces by drunkenness or otherwise is a defence (under the McNaghten Rules) to a crime charged.
So Question, whether the same test shall be apply here in interpreting S85 (2)(b).
Since S85 (2)(b) is an attempt to incorporate rule 1 of Beard 1920 the test of insanity should be the same as that under English law i.e result of disease of the mind and not unsoundness of mind
In circumstances can intoxication bring about insanity i.e state of disease which causes a degree of madness? The most obvious example is where excessive drinking causes an attack of delirium tremens (delusion caused due to excessive consumption of alcohol)
Intoxication and crimes of “intention, specific or otherwise”
Section 86 (2) draws its inspiration from rule 2 of Beard 1920 with some differences in wording.
Relevance of incapacity to form intent
No mention of “incapacity” to form intent in S86 (2) but was mentioned in Rule 2 of Beard 1920
Question: Whether the accused was capable of forming an intention.
Proof of incapacity wills of course negative the mens rea In England today, no requirement that
There must be incapacity due to intoxication to negative the intention to commit a crime.
The prosecution has only to est. that the accused had the intent despite his intoxicated. An
Intoxicated man may be capable of forming intent but may not have the guts to commit the offence.
The onus of proof was on the prosecution to est. that notwithstanding the alleged intoxication the
Accused did form intent
Under the penal code the question of incapacity of the accused is itself relevant in determining his
Intent but relevant in determining whether the accused was or was not sufficiently intoxicated
In Hatchard (1983), The prosecution is required to negate the argument that the accused person did not have the intent necessary for the commission of the crime due to intoxication. But there must be evidence that the accused was so intoxicated and if this is not available by means of direct evidence the accused person has the onus of producing evdence that he was incapable of forming the necessary intention due to intoxciation.
