self-defence Flashcards
What type of defence is self-defence
a general defence
Where has the law been codified?
S.76 Criminal Justice and Immigration Act 2008: ‘Reasonable Force for purposes of self-defence etc’
What is S 76(3)
the question of whether the degree of force used by D was reasonable in the circumstances appears to be objective and subjective. The Act states that the jury must take into account the circumstances that D believed them to be
R v Beckford
the test to be applied for self-defence is that a person may use such force as is reasonable in the circumstances as he honestly believes them to be in the defence of himself or another
What happened in R v Beckford
police officers shot an unarmed man dead, who was trying to surrender. But they mistakenly believed he was armed and dangerous. Viewed subjectively, through mistaken belief may be reasonable to shoot someone armed and dangerous.
What happened in Gladstone Williams
D used force to prevent a man, A, from assaulting another man, B, when A was actually making a citizen’s arrest of B for robbery. The issue said whether the force that the D used on A, would have been reasonable if he had been the criminal that D believed him to be, rather than the good citizen he was in reality.
What happened in Faraj
D mistook a gas man for a burglar and used force to detain him. So he can rely on the mistaken belief as to the circumstances even though he is wrong, even though he is unreasonable in reaching the conclusion.
What is the test as to the circumstances D believed them to be
subjective
Which case influence Beckford
DPP v Morgan (rape at common law). Under Morgan as D who believes that his V consented was not a rapist, whether the belief was reasonable or not. The problem that no longer apply Morgan to rape cases, since Beckford Sexual Offences Act
What was held in R v Beckford regarding the subjective test
if a genuine belief, albeit without reasonable grounds is a defence to rape because it negatives the necessary intention, so also must a genuine belief in facts which, if true, would justify self-defence be a defence to a crime of personal violence because the belief would negative the intent to act unlawfully.” (per Lord Griffiths)
Can an insane belief generate self-defence?
No- Oye
Facts of One
if D thought police officers were evil spirits, then although the act does not mention insanity, it cannot be right to allow to D the benefit of a deluded mistake, a mistake based on insanity.
What happens when D’s belief is unreasonable
The less likely a jury will believe the belief
Where is it set out how the jury should approach mistaken belief
S 76(4) CJIA
What is the response to the subjective trigger
there must be an objective response in that the force used was reasonable and proportionate
Who decides was it reasonable force
The jury
R v Yaman on objective response
Section 76 makes it clear that the trigger for using force is assessed subjectively and the defendant’s response is to be assessed objectively. Thus if a person uses force in the belief that he is being attacked, then his response must be assessed objectively in the light of that subjective belief’
Scarlet on the objective response
- the judge gave the impression the test was purely subjective. It seemed to allow a defence, if D believed that it was necessary, even if the amount of force was unreasonable. (It was recognised that a person may not be able to weigh to an exact nicety the exact amount of force to be used).
Owino on the objective response
ndicated that the test was neither purely objective or subjective.
What type of force must be used
In non-householder cases S 76(6) if the force used is disproportionate by the standards of a reasonable man then the force used is unreasonable.
