"unless your Lordship rules that I cannot do so, that in considering the situation they are entitled to take into account the fact that my client has drunk large quantities of alcohol which may have given him a wholly warped perception of reality."
"The judge gave an impeccable direction on the ingredients of murder and upon the way in which intoxication may affect proof of intent to kill or to do serious bodily harm. Likewise impeccable was his direction on provocation, including the correct observation that, when considering whether a reasonable man would have been caused to lose his self-control, questions of drink are irrelevant. Finally he gave the classic direction on self-defence. He made no mention of the possibility that the appellant might be reason of intoxication have been mistaken as to the threat posed to him by McCloskey's action. This was no doubt because no one had taken the point. Counsel for the prosecution towards the close of the judge's directions saw fit to invite the judge to remedy what he plainly regarded as this lacuna in the charge to the jury. Counsel for the appellant wisely held his peace. The judge then gave this further direction: 'It might be a view that you might take -- I know not -- that this defendant thought he was under attack from the other man mistakenly and made a mistake in thinking that he was under attack because of the drink that was in him. If he made such a mistake in drink he would nevertheless be entitled to defend himself even though he mistakenly believed that he was under attack. He would be entitled in those circumstances to defend himself. But if in taking defensive measures, then he went beyond what is reasonable either because of his mind being affected by drink or for any other reason, then the defence of self- defence would not avail because, as I told you earlier on, you are entitled to defend yourself if it is necessary to do so, but the defensive measures that you take must be reasonable ones and not go beyond what is reasonable.' ...."
"Given that a man who mistakenly believes he is under attack is entitled to use reasonable force to defend himself, it would seem to follow that, if he is under attack and mistakenly believes the attack to be more serious than it is, he is entitled to used reasonable force to defend himself against an attack of the severity he believed it to have. If one allows a mistaken belief induced by drink to bring this principle into operation, an act of gross negligence (viewed objectively) may become lawful even though it results in the death of the innocent victim. The drunken man would be guilty of neither murder nor manslaughter."
"If the jury thought that in a moment of unexpected anguish a person attacked had only done what he honestly and instinctively thought necessary, that would be the most potent evidence that only reasonably defensive action had been taken."
"The reasonableness or unreasonableness of the defendant's belief is material to the question of whether the belief was held by the defendant at all. If the belief was in fact held, its unreasonableness, so far as guilt or innocence is concerned, is neither here nor there. It is irrelevant. Were it otherwise, the defendant would be convicted because he was negligent in failing to recognise that the victim was not consenting or that a crime was not being committed and so on. In other words the jury should be directed first of all that the prosecution have the burden or duty of proving the unlawfulness of the defendant's actions; secondly, if the defendant may have been labouring under a mistake as to the facts, he must be judged according to his mistaken view of the facts; thirdly, that is so whether the mistake was, on an objective view, a reasonable mistake or not. In a case of self-defence, where self-defence or the prevention of crime is concerned, if the jury come to the conclusion that the defendant believed, or may have believed, that he was being attacked or that a crime was being committed, and that force was necessary to protect himself or to prevent the crime, then the prosecution have not proved their case. If however the defendant's alleged belief was mistaken and if the mistake was an unreasonable one, that may be a powerful reason for coming to the conclusion that the belief was not honestly held and should be rejected. Even if the jury come to the conclusion that the mistake was an unreasonable one, if the defendant may genuinely have been labouring it, he is entitled to rely upon it."
"It is because it is an essential element of all crimes of violence that the violence or the threat of violence should be unlawful, that self- defence, if raised as an issue in a criminal trial, must be disproved by the prosecution. If the prosecution fail to do so the accused is entitled to be acquitted because the prosecution will have failed to prove an essential element of the crime, namely that the violence used by the accused was unlawful. If then 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 negatives the intent to act unlawfully."
"Is a defendant who raises the issue of self-defence entitled to be judged upon the basis that he mistakenly believed it to be the situation when that mistaken belief was brought about by self-induced intoxication by alcohol or other drugs?"
"It is not too late for the court of Appeal to repent and establish a sound basis of the law."
"Whether voluntary intoxication can be taken into account when considering a defence of self- defence to a crime of specific intent?"
