What is the most common type of non inane automatism
Intoxication
What case defines what intoxication is and what is it
R v Lipman
Intoxication by all drugs, not just alcohol
What is needed in order for the defence of intoxication to be successfully argued?
Must be so serios as to render that person automaton in the sense that they cant form intentions or be aware of unjustified risks
Must be so intoxicated as to be incapable of forming a mens rea
Whats the onus and standard of proof in relation to intoxication
Defence bring it up and no obligation to prove based on balance of probabilities
Prosecution must disprove the defence beyond all reasonable doubt
What acse talks about intocixation
AG v Manning
AG v MAnning
Accused kileld a woman after 8 pints of stout
Mere drunkness is not sufficient for the defence of intoxication
Intoxication must go so far to render person. incapable of knowing what theyre doing and know the consequences or probable consequences of his actuons
What are the 2 types of intoxication
What is self-induced intoxication
If person consumes drugs to render themself intoxcated
2 types of crime and intoxication
Specific intent
Basic intent
Whats a crime of specific intent
Threshold must be intention for mens rea, recklessness not sufficient to prove offence
cases on crimes of specific intent
DPP v Beard
AG v GAllagher
DPP v Beard
If the accused is so intoxicated that he cannot form the specific intent required for the offence, he cannot be convicted of that offence.
Self induced intoxication is a defence to a crime if because of the intoxication, the accused hadnt formed the required intention
AG v Gallagher
Accused planned to murder his wife while sober.
Drank alcohol to gain dutch courage or dull his conscience.
Killed his wife while drunk.
Held: Pre-formed intention (mens rea) is sufficient; intoxication does not remove it.
\
If intent exists before intoxication, self-induced drunkenness does not negate mens rea.
Intoxication cannot excuse a crime of specific intent if the accused drank to give himself “Dutch courage” to commit the crime.
What is a crime of basic intent
Recklessness is sufficient to constiute each part of the required mens rea
Cases on basic intent crimes
R v Caldwell (r v MAjewski
DPP v Reilly
R v Caldwell
In DPP v Majewski, the accused became voluntarily intoxicated through drugs/alcohol.
While intoxicated, he committed offences requiring recklessness (crimes of basic intent).
Holding:
Self-induced intoxication is NOT a defence for crimes of basic intent.
Reasoning: By voluntarily intoxicating himself, the accused recklessly disregarded the consequences of his actions.
Voluntary intoxication itself provides the mens rea for crimes of recklessness/basic intent.
DPP. v Reilly
Facts:
The accused voluntarily consumed a large amount of alcohol and later fell asleep.
During the night, he stabbed a baby repeatedly, killing it.
He claimed to have no recollection of the incident.
Holding:
Voluntary intoxication can be a defence for specific intent crimes (like murder) if it prevents the formation of intent.
It is NOT a defence for basic intent crimes (like manslaughter).
If lack of control (automatism) arises from self-induced intoxication, the defence does not apply.
The specific vs basic intent distinction is maintained in Irish law, as endorsed from DPP v Majewski.
What is involuntary intoxication
Where someone b no fault of their own becomesd intoxicated
Can give rise to full defence
Cases on involuntary intoxication
R v HArdle
R v Kingstom
DPP v Murphy
DPP v Lyons
R v HArdie
Accused took a number of valiium tablets cux he was sad that his gf broke up with him
RAther than calming him down they actually made him agressive and he started a fire at his gf house
Held: Accused couldnt have known that the tablets could intoxicate him and therefore could not have been voluntarily intoxicated
If he knew that the drug could do that, defence would not be available
R v Kingston
Facts:
The accused had pedophilic tendencies.
Another person drugged him (innocent/involuntary intoxication) to set up a sexual assault.
While under the influence, the accused sexually assaulted a boy.
Holding:
Involuntary or innocent intoxication does not automatically excuse criminal liability.
If the accused still forms the necessary mens rea (criminal intent), he can be convicted.
Key principle: “A drunken intent is still an intent.”
The intoxication only made him act more readily on an intent he already possessed; it did not negate the mens rea.
FE1 Takeaways:
Involuntary/innocent intoxication may be a defence only if it prevents the formation of mens rea.
If mens rea is present despite intoxication, the accused is still criminally liable.
Always distinguish incapacity to form intent (possible defence) vs. acting on pre-existing intent (no defence).
DPP v Murphy
Facts:
The accused set fire to a house on Innisboffin, County Galway, killing three sisters.
He was on painkillers for a rib fracture and had been drinking heavily before the incident.
Witnesses described strange behaviour and signs of alcohol intoxication, with some suggesting he may also have been drugged.
The accused pleaded involuntary/innocent intoxication as a defence.
Legal Principle:
Involuntary or innocent intoxication can be a full defence if the person was so impaired that they:
Did not know what they were doing, and
Had no control over their actions.
If the person knew what they were doing or retained control, the defence fails.
Holding:
The court did not accept the defence, implying the accused retained awareness or control despite intoxication.
DPP v Lyons
Facts:
The accused was charged with sexual assault.
He pleaded not guilty, claiming involuntary intoxication due to prescription anti-cholesterol drugs.
He argued that the drugs caused a mental state in which he did not know what he was doing or lacked control.
Expert evidence was presented to support this claim.
Holding:
The jury rejected the defence of involuntary intoxication.
The accused was found guilty.
Defence of intoxication in relation to murder
article
Duurack- killing while under the influence
Intoxication rarely relied upon in murder trials in Ireland, despite widespread alcohol consumption.
Voluntary intoxication is considered an individual choice; Irish law does not excuse diminished mental capacity caused by alcohol.
Partial defence to murder exists if the accused did not form the specific intent to kill.
The jury decides intent based on all evidence, including alcohol consumption.
If voluntary intoxication negates specific intent, the accused may be convicted of manslaughter instead of murder.
Innocent (involuntary) intoxication can be considered by the jury when determining whether the accused had control or awareness of their actions.
Key question for the jury: Did the accused have the requisite intention, inferred from all circumstances including intoxication?
