General Defences Flashcards
What can the defence of intoxication be used for?
- A way to negate the mens rea of an offence; or
- An influencing factor on another legal principle/ defence.
When can intoxication operate to negate the mens rea?
- In any crime where the intoxication is caused by drink or drugs taken involuntarily, i.e. ‘spiking’ or ‘lacing’ someone’s drink or food with a drug or alcohol.
- In any crime where the intoxication is caused by drugs taken voluntarily, but in bona fide pursuance of medical treatment.
- In any crime where the intoxication is caused by non-dangerous drugs taken voluntarily (dangerous drugs are those which are illegal or alcohol)
- In crimes where a specific intent is required (generally where the offence cannot be committed recklessly).
What Qs should you ask to see if intoxication negates MR?
- Is the defendant voluntarily intoxicated or involuntarily intoxicated?
- Is the intoxicant a dangerous alcohol/drug or a non-dangerous drug?
- Is it a crime of basic intent or specific intent?
When can voluntary intoxication be a defence?
The House of Lords held that voluntary intoxication could be a defence to a charge of specific intent, where the defendant’s intoxication negated the mens rea required for the offence charged.
However, voluntary intoxication would not be a defence to a charge of basic intent.
How does intoxication work to negate MR?
Intoxication working to negate the mens rea
The court will ask did the defendant form the mens rea even though intoxicated?
* If yes- a drunken intent is still intent, D will be criminally liable, see Kingston. Another example would be if D takes drugs or alcohol in order to commit a specific intent crime (sometimes referred to as ‘Dutch courage’).
* If no- D lacks the mens rea and will be acquitted e.g. D was so intoxicated they did not know what they were doing.
The court will ask did the defendant form the mens rea even though intoxicated, in cases of:
* Involuntary intoxication (such as being drugged without consent);
* Voluntary intoxication by non-dangerous drugs (e.g. Hardie, the D who took Valium to calm his nerves); or
* Voluntary intoxication and D has committed a specific intent crime (e.g. murder).
Where D is voluntary intoxicated by dangerous drugs/ alcohol and commits a less serious crime of basic intent (where recklessness is a form of mens rea available), the defendant will be deemed reckless if they would have foresaw the risk of harm if sober, Coley, McGhee and
How does intoxication work with the other defences?
Intoxication and other defences
* Self-defence- D cannot rely on a drunken mistake as to the need to use self-defence.
* Loss of control and diminished responsibility- can still be pleaded if D was intoxicated but it does impact various aspects of the legal analysis.
* Consent- if the jury are satisfied that V consented to the accidental infliction of injury or D (even wrongly) believed that V consented (due to their intoxication), D may have a defence, Richardson & Irwin.
* Statutory defences- where these allow for an honest belief, D will be able to use the defence even if their belief is due to voluntary intoxication, see Jaggard v Dickinson on the lawful excuse defence for criminal damage.
Involuntary intoxication may be raised successfully as a defence to which crimes?
Crimes of both specific and basic intent involving dangerous or non-dangerous substances
When will intoxication prevent the defendant from using another defence?
When a drunken mistake caused the defendant to use self-defence
What is the question a court will ask regarding a defendant’s mens rea if they are voluntarily intoxicated by dangerous drugs/ alcohol and commit a basic intent offence?
Would the defendant have formed the mens rea if sober?
what happens if D has a valid justification or excuse for their behaviour?
If a valid and complete defence exists, D will not be criminally liable.
Can consent prevent D from being liable for a crime?
Sometimes
For example, for property offences there is a statutory defence for a defendant who believes the owner consents. This is found in the Criminal Damage Act 1971, s 5(2)(a) and the Theft Act 1968, s 2(1)(b).
What are the elements for the defence of consent?
There are two elements to consent, whether the:
- victim consented; or
- defendant honestly believed the victim consented.
It is for the prosecution to prove both that the victim did not consent and that the defendant did not believe in the victim’s consent. So if the defendant wrongly believed the victim consented, the defence could be available, R v Richardson and Irwin. Equally if the victim consented, even if the defendant did not know this, the defence could be available. Whether the defence of consent is available will depend on the level of harm inflicted on the victim and the circumstance in which the harm was inflicted.
When is consent a defence to an offence against the person?
The general rule is that consent is only available as a defence to assault and battery.
Consent is available as a defence, even where actual bodily harm or worse is caused provided the defendant:
* intended only to commit a battery with the consent of the victim; and
* did not see the risk of inflicting actual bodily harm.
If however, the defendant intended to cause actual bodily harm, then consent is not available as a defence, even if the victim consented (unless the conduct falls into one of the exceptions which follow).
What the requirements for consent for offences against the person?
s the offence more than assault/ battery?
· No- Consent is available if: V consented or D honestly believed that V was consenting.
· Yes- Did D intend to cause ABH or above?
o Yes- Consent is no available unless any of the exceptions apply.
o No & did not see risk- Consent is available, Meachen.
o No & reckless- No guidance from court but if prohibited harm then check to see if one of the exceptions apply.
What are the exceptions to the general rule that consent is only available as a defence to assault and battery? If ABH was caused what are the exceptions for consent that could be used for D’s defence?
the victim can consent to offences against the person of ABH and above if the situation falls under one of the public interest exceptions such as:
- Medical treatment;
- Sport;
- Horseplay;
- Tattooing, body piercing and personal adornment; and
- Sexual gratification/ accidental infliction of harm.
What is the exception for consent for medical treatment?
Consent can be given for surgery and other medical treatment that causes harm. Consent can be given to a high risk of death.
What is the exception for consent for sport?
Consent to incidental injury during sport - but if the offence against the person is caused “off the ball” there is no defence of consent
What is the exception for consent for horseplay?
R v Jones (1986) 83 Cr App R 375
Some boys at a youth club tossed two other boys into the air, resulting in one suffering a ruptured spleen and the other a broken arm. The Court of Appeal held that they ought to have been allowed to raise the issue of consent to injuries sustained through ‘rough and undisciplined’ horseplay, for the jury to then consider.
What is the exception for consent for Tattooing, body piercing and personal adornment?
R v Wilson [1997] QB 47 (CA)
FACTS: The defendant used a hot knife to brand his initials onto the buttocks of his wife, at her request. He argued consent to a charge under the OAPA 1861 s 47, and was successful.
DOES NOT INCLUDE BODY MODIFICATION in particular the removal of an ear, the removal of a nipple and the division of a tongue into a fork like a reptile, in the category of tattooing and personal adornment.
What is the exception for consent for Sexual gratification/ accidental infliction of harm exception?
R v Dica [2004] QB 1257
The Court of Appeal held that if the complainant consents to the risk of contracting HIV through having sexual intercourse, the defendant does have a defence to a charge under the OAPA 1861, s 20.
R v Brown
The consensual sadomasochistic activity that occurred in R v Brown such as burning their genitals or beatings for sexual pleasure was not deemed to be a suitable exception. The courts considered the nature of the act rather than the circumstance in which it occurred.
R v Emmett (1999) The Times, 15 October
FACTS: The parties were involved in consensual activities with the defendant tying a plastic bag over his fiancée’s head in order to increase her sexual pleasure. He also, with her consent, poured lighter fuel on her breasts and set fire to it.
HELD: The court saw this as violent conduct which moved beyond those acts which can be consented to.
What is another defence for offence against the person that is not consent?
A parent has a defence of reasonable chastisement in applying force to a child.
In considering whether or not a parent could use this defence, the jury must look at the nature and context of the parent’s behaviour, its duration, the physical and mental consequences for the child, and the reasons why the punishment was inflicted.
What does self-defence refer to?
here a person acts to:
* protect themselves;
* protect someone else;
* protect property;
* prevent a crime; or
* assist in the arrest of an offender.
What are the statutory and common law defences for self-defence?
The CJIA 2008, s 76(2) identifies the defences to which the section applies:
(a) the common law defence of self-defence; and
(aa) the common law defence of defence of property; and
(5) the defence provided by section 3(1) of the Criminal Law Act 1967 … (use of force in prevention of crime or making arrest).
The common law defence envisaged two possible reasons for acting:
* In the protection of life and limb of yourself or another: see e.g. R v Gladstone Williams(1984) 78 Cr App R 276 (CA).
* In the protection of property: R v Hussey (1925) 18 Cr App R 160 (CA).
When can self-defence be used?
self defence can only be used to protect yourself or another, or property from imminent attack: i.e. from a threat of physical force, not a threat to one’s peace of mind
