General Defences Flashcards
(41 cards)
WHAT IS A GENERAL DEFENCE?
A general defence is one that may be raised to all crimes. Where a general defence is successfully pleaded, the defendant will avoid liability entirely.
WHAT IS THE FIRST STEP IN CONFRONTING INTOXICATION?
By making two crucial distinctions:
- Between substances which are regarded as
intoxicants and those that are not - Between intoxication for which the defendant is
responsible and intoxication for which the defendant
is not responsible.
WHAT SUBSTANCES ARE REGARDED AS INTOXICANTS?
Any substance commonly known to produce effect generally associated with intoxication can be regarded as intoxicants.
Hardie [1985] indicates that a substance may be regarded as an intoxicant when it produces the effects which would be expected of it.
WHAT IS VOLUNTARY INTOXICATION?
Where the defendant knows they were consuming an intoxicant or where they realised they may be taking an intoxicant.
Allen [1988] held that the defendant will still be regarded as voluntarily intoxicated even if they underestimated/made a mistake as to the strength of the intoxicant.
WHAT IS INVOLUNTARY INTOXICATION?
Where the defendant is unaware they were consuming an intoxicant.
WHAT MUST THE DEFENDANT LACK IN BOTH TYPES OF INTOXICATION?
The mens rea of the offence.
WHAT IS THE LIABILITY WHERE THE DEFENDANT IS INVOLUNTARILY INTOXICATED?
The defendant is entitled to produce evidence of the intoxication to refute the prosecutions allegations of mens rea.
The rules were established in Kingston [1994}
WHAT IS THE LIABILITY WHERE THE DEFENDANT IS VOLUNTARILY INTOXICATED?
The rules were established by the House of Lords in DPP v Majewski [1976] and are based on a distinction between specific intent and basic intent offences.
WHAT ARE SPECIFIC INTENT OFFENCES?
These require proof of intention and nothing else.
This category includes:
- murder
- causing GBH with intent to cause such harm
- theft
- robbery
WHAT ARE BASIC INTENT OFFENCES?
Proof of recklessness is sufficient.
This category includes:
- manslaughter
- assault
- criminal damage
WHAT ARE THE RULES ESTABLISHED IN DPP V MAJEWSKI [1976] WHERE A DEFENDANT IS CHARGED WITH A SPECIFIC INTENT OFFENCE?
The defendant may introduce evidence of intoxication in asserting that at the time of the offence, they did not have the required intention.
The issue whether the defendant did or did not form the intention - not whether they are capable of forming it.
Further to Gallagher [1963] the defendant cannot use the defence of intoxication where they formed the intent to commit the crime, but then gets drunk as to acquire ‘Dutch courage’.
WHAT ARE THE RULES ESTABLISHED IN DPP V MAJEWSKI [1976] WHERE A DEFENDANT IS CHARGED WITH A BASIC INTENT OFFENCE?
The defendant is simply not allowed to introduce evidence of voluntary intoxication to explain why they were not aware of the risk.
WHAT WILL THE DEFENDANT BE CHARGES WITH IF THEY RAISE A DEFENCE OF INTOXICATION IN RESPECT OF A SPECIFIC INTENT OFFENCE?
A person who raises intoxication as a defence to avoid liability for conviction of a specific intent offence, will inevitably be charges of any associated basic intent offence.
For example:
In Lipman [1970] the defendant, who killed his girlfriend whilst on an LSD trip, avoided liability for murder but was convicted of manslaughter.
WHAT IS THE DEFENCE OF ‘MISTAKE’?
Merely a denial of mens rea
The defendant is saying that they could not have intended or known the risk of the consequence.
WHAT CAME OUT OF THE CASE B (A MINOR) V DPP [2000] IN RESPECT OF THE DEFENCE OF ‘MISTAKE’?
There is no need for the mistake to have been reasonable. What is important, is that it prevented the defendant from having the necessary mens rea.
WHAT IS ‘DURESS’?
There are two forms of duress:
- Duress by threats
- Duress by circumstance
WHAT DOES THE DEFENDANT ARGUE FOR DURESS BY THREATS?
That they were compelled to commit an offence because of direct threats of harm to themselves or someone for whom they are responsible.
WHAT DOES THE DEFENDANT ARUGE FOR DURESS BY CIRCUMSTANCE?
That they were compelled to commit an offence because of the circumstances they found themselves in.
WHEN IS THE DEFENCE OF DURESS BY CIRCUMSTANCES AVAILABLE?
Where the defendant acts reasonably and proportionately to avoid a threat of death or serious injury.
WHERE THE DEFENCE OF DURESS BY CIRCUMSTANCES IS AVAILABLE, WHAT MUST THE JURY DETERMINE?
- Was the defendant impelled to act as they did as a
result of what they reasonably believed to be the
situation in which they had good cause to fear death
or injury? - If so, would a sober person of reasonable firmness,
with the same characteristics as the defendant, act as
the defendant did?
If the answer is YES to both, the defendant must be aqcuitted.
WHAT DID THE CASE OF ‘RE A (CHILDREN) (CONJOINED TWINS: SURGICAL SEPARATION) [2000]’ HOLD?
Doctors would have a defence of necessity if the operated to separate the twins in order to prevent the weaker twin causing the death of the stronger twin.
Necessity can therefore be a defence for murder - in limited cases
WHAT ARE THE DIFFERENCES BETWEEN DURESS BY CIRCUMSTANCE AND NECESSITY?
With duress by circumstance, there needs to be a threat of death or serious injury to the defendant or another. This is not the case with necessity (Pipe v DPP [2012])
To please necessity, the defendant will need to demonstrate he took the option which was the ‘lesser of two evils’
Duress can be based on mistaken belief. Necessity cannot.
WHAT ARE THE REQUIREMENTS FOR DURESS BY THREATS?
Further to Hasan [2005] the requirements for this defence have tightened.
The defence CANNOT succeed if:
- The crime is murder or attempted murder - the
defendant is expected to withstand pressure (Howe
[1987]) - The defendant is at fault in associating themselves
with a person or group whom they knew might
pressure them into committing an offence. This
applies to:- Terrorist & Criminal gangs (Sharp [1987])
- Violent drug dealers (Heath [2000])
WHAT TWO TESTS MUST THE DEFENCE OF DURESS BY THREATS SATISFY?
If the crime is NOT murder or attempted murder and the defendant is not at fault, the plea must satisfy two tests:
- A Subjective test
- An Objective test
