Does not provide defence as such but it is
relevant as to whether or not the defendant
has the mens rea for the offence.
Whether the defendant is guilty
depends on whether the intoxication was
voluntary or involuntary and whether the
offence charged is one of specific intent
or basic intent.
VOLUNTARY INTOXICATION
Where D has chosen to take an intoxicating
substance. It also includes when D takes a
prescribed drug knowing it will make him
intoxicated.
If D is so intoxicated that he hasn't
formed the mens rea for a specific intent
offence then he is not guilty.
DPP V BEARD
GALLAGHER - D decided to kill his
wife. He drank whisky to give himself
'Dutch courage' before killing her. He
was convicted of murder.
It was held that drunk intent is still
intent.
Where the offence is one of
basic intent then intoxication is
not a defence. This is because
voluntarily becoming intoxicated
is considered reckless and
recklessness is sufficient for the
mens rea of basic intent
offences.
MAJEWSKI
INVOLUNTARY INTOXICATION
This covers situations where D was
unaware he was taking an
intoxicating substance, eg. his soft
drink was laced.
The test is; did D have the mens rea
when he committed the offence?
KINGSTON - In this case it was
decided that even if D wouldn't have
committed the offence if he hadn't of
been intoxicated, but had the mens
rea when committing the offence, he
cannot use the defence.
HARDIE - was not convicted
because he didn't have the mens rea
nor was he reckless in taking the
intoxicating substance, therefore
cannot be convicted of either a
specific or basic intent offence.
INTOXICATED MISTAKE
Where D is mistaken about a key fact
because he is intoxicated.
LIPMAN - D had take LSD before falling asleep
at his girlfriends flat. D was hallucinating and
mistook his girlfriend for attacking snakes. He
strangled her. He was convicted of manslaughter
because he didn't intend to kill or cause GBH to a
human being, but he was reckless in taking the
substance.
If the mistake is about the amount of force
or need for self-defence the defendant will
not have a defence
O'GRADY
HATTON
Set out by the Criminal Justice and Immigration Act 2008
JAGGARD V DICKINSON - An exception to the
rule of intoxicated mistake is the one in this case
set out in the Criminal Damage Act 1971. This
allows an honest belief that the property owner
would have consented to the damage.
A02
The defence is largely policy based. The Criminal
Justice and Immigration Act 2008 helps protect the
public by prevention of crime as defendant cannot use
being intoxicated as an excuse for the unacceptable
behaviour.
For specific intent offences like murder there are fall back
offences and the defendant would be charged with the basic
intent offence of manslaughter. However, for offences like theft
there are no fall back offences and the defendant will not be
guilty of any offence. Is it correct for them to walk free?
The Butler Committee proposed
the creation of a new offence of
'dangerous intoxication' to cover
situations like this which would
carry a maximum sentence of 1
year imprisonment. This would
meet the needs of public
protection as well as deter others
when they voluntary intoxicate
themselves.
