Mens Rea Flashcards
Mens rea
state of mind
Criminal Justice Act 1967 which says (under s. 8) that a court/jury, in determining whether a person has committed an offence:
shall not be bound in law to infer that he intended or foresaw a result of his actions by reason only of its being a natural and probable consequence of those actions
shall decide whether he did intend or foresee that result by reference to all the evidence, drawing such inferences from the evidence as appear proper in the circumstances.
Foresight
Foresight of the probability of a consequence does not amount to an intention to bring that consequence about, but may be evidence of it.
Argument
at the time of the criminal act there was a probability of a consequence;
the greater the probability of a consequence, the more likely it is that the defendant foresaw that consequence;
if the defendant foresaw that consequence, the more likely it is that the defendant intended it to happen.
Specific intent
Particular intention to bring about a specific consequence at the time of the criminal act. E.g. murder and burglary (without the intent the offence does not exist.
Basic intent
Bring about given circumstances e.g. maliciously wounding or inflicting GBH or taking a conveyance. Recklessness will often be enough to satisfy the mental element.
OFFENCES OF ‘SPECIFIC’ AND ‘BASIC’ INTENT
Whether an offence is one of ‘specific’ or ‘basic’ intent connects to the issues around voluntary or involuntary intoxication.
Intoxication can be divided into two categories
Voluntary intoxication (you got yourself in that condition)
involuntary intoxication (you are not responsible for getting in that condition)
Specific intent offence and intoxication
Where an offence is a specific intent offence, such as murder, defendants who were voluntarily intoxicated at the time the offence was committed may be able to show they were so intoxicated that they were incapable of forming the mens rea required for the offence.
DPP v Majewski [1977]
An individual who is voluntarily intoxicated would not be able to say this if accused of an offence of basic intent as the courts have accepted that a defendant is still capable of forming basic intent even when completely inebriated.
Basic intent offence and intoxication
Where the offence is a basic intent offence, such as s. 47 assault, defendants who were involuntarily intoxicated (perhaps because their drink had been spiked) at the time of the offence may be able to say that they lacked the mens rea for that basic intent offence.
Voluntary and Involuntary intoxication
Voluntary intoxication can be raised in answer to a charge of an offence of specific intent but not basic intent; involuntary intoxication can be raised in answer to a charge of both specific and basic intent.
R v Allen [1988]
If defendants simply misjudge the amount or strength of intoxicants which they take, this will not be regarded as involuntary intoxication.
Defendant knowingly drinks beer but is unaware that the beer has been laced with vodka, this will still be ‘voluntary’ intoxication
R v Kingston [1995]
If defendants can be shown to have actually formed the required mens rea necessary for the offence, intoxication (voluntary or involuntary) will not be available as a drunken intent is still an ‘intent’
Source of the intoxication can be drink or drugs.
The courts will consider the known effects of the drug in deciding whether or not defendants had formed the required degree of mens rea; the characteristics of the drugs will be relevant in determining whether defendants behaved recklessly in taking them.
