“Not quite an end of it, because if the prosecution prove, against either Paul Carpenter or Tracy Carpenter, that he or she participated in the violence, and that, when he or she did so, he or she knew that Joe Carpenter had a knife, and intended to use it to cause some injury or harm, but falling short of killing or causing serious bodily harm, or realised that he might use a knife to cause some injury, falling short of really serious harm, then whoever was in that state of mind would be guilty not of murder but of manslaughter. Why? Because the killing would have been unlawful and a shared intention to that extent, but not a shared intention to kill or cause serious bodily harm.”
“1. In respect of Paul Carpenter, is it proved that by the time he arrived at the car park he knew that Joe Carpenter was armed with a knife? 2. If no, your verdict will be ‘not guilty’. 3. If yes to (1) go on to answer this question: Is it proved that he shared Joe Carpenter’s intention to kill or to do really serious injury or realised that Joe Carpenter might use the knife with that intention and nevertheless took part by restraining Frederick Price sr, to prevent him from intervening in order to protect Shane Price? 4. If yes to (3), your verdict will be ‘guilty’. 5. If no to (3), go on to answer this question: Is it proved that he knew that Joe Carpenter had a knife and intended to use it to cause some injury or harm but falling short of killing or causing really serious injury or he realised that Joe Carpenter might use the knife to cause some injury falling short of really serious injury and nevertheless took part by restraining Frederick Price sr, to prevent him from intervening in order to protect Shane Price? 6. If yes to (5), your verdict will be ‘not guilty of murder but guilty of manslaughter’. 7. If no to (5), your verdict will be ‘not guilty’. You should then answer the same questions in relation to Tracy Carpenter, substituting her name for that of Paul Carpenter and the name ‘Eileen Price’ for ‘Frederick Price, sr’.”
“52. As regards the second point, it is not part of the law of joint enterprise that a secondary party, B, must share the mens rea of the principal offender, A – see Slack[1989] QB 775 and Hide[1991] 1 QB 134 where it was made clear that foresight of what the principal may do is sufficient mens rea for the accessory even if there is no actual agreement between him and the principal. In Powell and English itself a major question was whether a secondary party in a murder case must be shown to have been actuated by the mens rea required in the principal offender, and the question was answered in the negative. The subject matter of a joint enterprise is not a state of mind or intention but an objective act which it is contemplated will or might be done. 53. That proposition we think provides the key to the right result in a class of case which is not, so far as counsel’s researches have revealed, distinctly the subject of any authority. Suppose that the participants in a joint enterprise all propose or foresee the same kind of violence being inflicted on their victim, let it be punching with the possibility of kicking to follow. On that they are at one. But two of them harbour a subjective intention to inflict really serious injury by means of such violence. The third harbours only, or foresees or intends only, that some harm might be done. One of those actuated by an intent to do grievous bodily harm punches or kicks the victim just as all three foresaw. The victim falls and suffers a subdural haemorrhage and dies. The principal is guilty of murder as he had the mens rea required. So also is the accessory who, like him, intended or contemplated the infliction of the serious injury. What of the third adventurer? Mr Fitzgerald submits he must escape altogether because he did not foresee a murderous state of mind would be harboured by his fellows. Yet if his fellows had entertained only an intention to do some harm and otherwise the facts were the same, all three would be guilty of manslaughter. It does not seem to us that that can be right. In such a case there was a joint enterprise to inflict some harm, and that is not negated by the larger intentions of the other two adventurers. In our judgment in such a case there is no reason why the participants should not be convicted and sentenced appropriately as their several states of mind dictate ….”
“Thus this court proceeded upon the basis that the second participant was guilty of murder because he at least foresaw the deliberate infliction of GBH, whereas the third was not because he did not. That is precisely the law as we have endeavoured to state it. This court was not beginning to say that D2 could be guilty of murder without foresight that D1 might act with murderous intent.”
“125. This submission cannot succeed in the light of the decision of the House of Lords in Rahman [R v Rahman[2008] UKHL 45 ,[2009] 1 AC 129 ], upholding the decision of the Court of Appeal. In Rahman it was argued that the fact that the stabber intended to kill (or may have intended to kill) took (or could take) the stabber’s actions out of the scope of the common design because what the stabber did was ‘fundamentally different’ from what the appellants had intended or foreseen. All that they had intended or foreseen was the infliction of serious bodily harm. That argument was rejected. 126. The argument presented in this case on behalf of those convicted of manslaughter is only a slight variation on this argument. If a defendant knowing that the stabber had a knife intends the stabber to cause some injury to the deceased or realises that he might cause some injury, then the fact that the stabber stabbed the deceased intending to kill him is not ‘fundamentally different’ from what the defendant had intended or foreseen. Counsel could point to no authority to the effect that the fundamentally different rule in manslaughter cases is different to the rule as it applies to murder cases. It follows that, in so far as this argument is concerned, there was no misdirection and it also follows that the judge was entitled if not obliged to leave manslaughter to the jury.”
“In Yemoh the Court of Appeal confirmed that P’s greater mens rea from that which D foresaw will not prevent D being guilty of manslaughter. D, a member of the gang, knew that another member of the gang, P, had a knife and intended that other to cause some injury to V or realized that he might cause some injury. The fact that P stabbed V intending to kill (i.e. with graver mens rea) did not absolve D. If D intended or foresaw that one of the group might cause non-serious injury, D remains liable for manslaughter even if P kills with intent to kill or do gbh, unless P’s manner of doing so is fundamentally different from that D foresaw.”
“Other relevant factors have been … the removal of the ability of the jury to return a verdict of guilty of manslaughter in circumstances where D sets out with others on a criminal venture in joint possession of weapons, but without intent to kill or cause serious bodily harm, and P murders V in the course of it (the scenario considered in Reid).”
“Some would argue, in company with Lord Mustill in Powell and English, that where D and P embark on a criminal venture in which P goes further than D wishes, but foreseeably so, D has a measure of culpability for P’s act and V’s resulting death but usually at a lower level than P. When Reid was good law, the difference was accommodated by the possibility of a manslaughter verdict, but that is no longer available; D is guilty of murder.”
“45. The essence of Mr Waterman’s argument can be stated in this way. In cases where the common purpose is not to kill but to cause serious harm, D is not liable for the murder of V if the direct cause of V’s death was a deliberate act by P which was of a kind: (a) unforeseen by D; and (b) likely to be altogether more life-threatening than acts of the kind intended or foreseen by D. Mr Watson QC for the prosecution did not dissent from this proposition. The reference to a ‘deliberate act’ is to the quality of the act – deliberate and not by chance – rather than to any consideration of P’s intentions as to the consequences. … 47. In our judgment the proposition stated at [45] is both sound in principle and consistent with Powell and English and Rahman. It would not be just that D should be found guilty of the murder of V by P, if P’s act was of a different kind from, and much more dangerous than, the sort of acts which D intended or foresaw as part of the joint enterprise.”
“Accordingly, in the appeal of English, I consider that the direction of the trial judge was defective … because in accordance with the principle stated by Lord Parker CJ in Reg v Anderson, at p.120B, he did not qualify his direction on foresight of really serious injury by stating that if the jury considered that the use of the knife by Weddle was the use of a weapon and an action on Weddle’s part which English did not foresee as a possibility, then English should not be convicted of murder. As the unforeseen use of the knife would take the killing outside the scope of the joint venture the jury should also have been directed, as the Court of Criminal Appeal held in Reg v Anderson, that English should not be found guilty of manslaughter. On the evidence the jury could have found that English did not know that Weddle had a knife. Therefore the judge’s direction made the conviction unsafe and in my opinion his appeal should be allowed and the conviction for murder quashed.”
