intoxication Flashcards
mental capacity defence
intoxication
D has taken drugs, alcohol, or other substances that have substantially incapacitated their judgement
>either D isn’t capable of forming the mens rea
>it has caused D to make a mistake
when might a person be intoxicated
> alcohol
drugs
other substances e.g. sniffing glue
may have a defence depending on
> the intoxication was voluntary or involuntary
the offence is one of basic or specific intent
basic intent
these have recklessness as part of the mens rea
e.g manslaughter , s.20 and 47 OAPA 1861, assault, battery, criminal damage
specific intent
these have intent only as mens rea
e.g. murder, s.18 OAPA
voluntary intoxication
where the D:
>has chosen to take an intoxicating substance
>knows that the effect of taking a prescribed drug will be to make them intoxicated
DPP v Beard
D whilst intoxicated raped a 13 yr old girl and put his hand over he mouth
she died from suffocation
‘‘if he was so drunk that he was incapable of forming the intent recquired, he could not be convicted of a crime which’’ only requires intent
intoxication must negate mens rea
Sheehan and Moore
Ds were drunk and threw petrol over a tramp and set fire to it.
they were too drunk to have formed any intent to kill or cause GBH.
guilty of manslaughter (basic intent offence)
drunken intent is still intent
where the D has the necessary mens rea despite their intoxicated state, then they are still guilty of an offence, as drunken intent is still intent.
Gallagher
D decided to kill his wife. He brought a knife and a bottle of whiskey. He drank a large amount of whiskey for ‘‘dutch courage’’ before killing his wife.
he formed intent before becoming intoxicated
R v Coley
D was a regular user of cannabis and one evening watched a violent video game. Later on he entered neighbours house and attacked two people with a knife. claimed psychiatric injury but convicted of murder as state of mind was caused by voluntary intoxication
Allen
claimed he didn’t realise the strength of his wine that he had been given did not make the intoxication involuntary
voluntary intoxication can be a defence to specific intent crimes but NOT to basic intent crimes
R v Majewski - consumed large quantities of drugs and alcohol, then attacked the landlord of the pub also attacked the police who tried to arrest him.
becoming intoxicated was a reckless course of conduct so defence couldn’t be used when mens rea includes recklessness
Richardson and Irwin
D threw V over a balcony while drunk
judge should’ve directed that the jury had to be sure that Ds would have foreseen the risk of injury had they been sober
past intoxication
where the D is suffering from a mental disorder brought by past voluntary intoxication], he can use this as a defence
involuntary intoxication
includes the following situations:
1. D doesn’t know they are consuming an intoxicant
2. D consumes an intoxicating substance under medical advice or an intoxicant commonly known as a ‘‘sedative’’ has an unexpected effect
D doesn’t know they’re taking an intoxicating substance
for example, drink is ‘spiked’ with alcohol or drugs OR prescribed drug has an unexpected effect
R v Hardie
D consumed out of date Valium tablets prescribed to his partner then set fire to a wardrobe.
where D voluntarily takes a non-dangerous drug that has an unexpected effect, although not prescribed to him
Kingston
D was invited to a house where his drink was drugged by a man who wanted to blackmail him. He was shown a 15yr old boy who was unconscious and told him to abuse him.The D had paedophilic tendencies and did so.
Formed mens rea before becoming intoxicated
R v Lipman
D and his girlfriend took drugs - D stuffed a bed sheet down her throat as he thought he was fighting a snake.
Acquitted of murder as he was unable to form mens rea
convicted of manslaughter as its a basic intent offence so could use defence of voluntary intoxication
R v O’Grady
D and V had been heavy drinking. D woke up and claimed he woke up to V hitting him so he grabbed a glass ashtray hit V with It and went back to sleep . V was dead
D cannot rely on self defence where mistake of the fact was induced by intoxication
R v Hatton
Basic intent rule applied to specific intent- a drunken mistake about the amount of force required in self-defence was not a defence
