“To accept this type of reasoning would be to fix an accessory with consequences of his acts which he did not foresee and did not desire or intend. The modern development of the criminal law has been away from such an approach and towards a greater emphasis on subjective tests of criminal guilt, as Sir Robin Cooke pointed out in Chan Wing-Siu . Although the rule remains well entrenched that an intention to inflict grievous bodily harm qualifies as the mens rea of murder, it is not in my opinion necessary to apply it in such a way as to fix an accessory with liability for a consequence which he did not intend and which stems from an act which he did not have within his contemplation. I do not think that the state of the law compels me to reach such a conclusion, and it would not in my judgment accord with the public sense of what is just and fitting.”
“… one of them has departed completely from the concerted action of the common design and has suddenly formed an intent to kill and has used a weapon and acted in a way which no party to that common design could suspect …". Secondly Mr Harrison relied on a passage in the judgment of Beldam LJ (for the Court of Appeal) in R v Uddin[1999] QB 431 , 441 where he said: “Notwithstanding these difficulties, we think that the principles applicable to a case such as the present are as follows: (i) Where several persons join to attack a victim in circumstances which show that they intend to inflict serious harm and as a result of the attack the victim sustains fatal injury, they are jointly liable for murder; but if such injury inflicted with that intent is shown to have been caused solely by the actions of one participant of a type entirely different from actions which the others foresaw as part of the attack, only that participant is guilty of murder. (ii) In deciding whether the actions are of such a different type the use by that party of a weapon is a significant factor. If the character of the weapon, e.g. its propensity to cause death, is different from any weapon used or contemplated by the others and if it is used with a specific intent to kill, the others are not responsible for the death unless it is proved that they knew or foresaw the likelihood of the use of such a weapon.”
“If in the course of a joint enterprise to inflict unlawful violence the principal party kills with an intention to kill which is unknown to and unforeseen by a secondary party, is the principal’s intention relevant, (i) to whether the killing was within the scope of a common purpose to which the secondary party was an accessory? (ii) to whether the principal’s act was fundamentally different from the act or acts which the secondary party foresaw as part of the joint enterprise?”
“If B realises (without agreeing to such conduct being used) that A may kill or intentionally inflict serious injury, but nevertheless continues to participate with A in the venture, that will amount to a sufficient element for B to be guilty of murder if A, with the requisite intent, kills in the course of the venture. As Professor Smith points out, B has in those circumstances lent himself to the enterprise and by so doing he has given assistance and encouragement to A in carrying out an enterprise which B realises may involve murder.”
“It seems to this court that to say that adventurers are guilty of manslaughter when one of them has departed completely from the concerted action of the common design and has suddenly formed an intent to kill and has used a weapon and acted in a way which no party to that common design could suspect is something which would revolt the conscience of people today.”
“What public policy requires was rightly identified in the submissions for the Crown. Where a man lends himself to a criminal enterprise knowing that potentially murderous weapons are to be carried, and in the event they are in fact used by his partner with an intent sufficient for murder, he should not escape the consequences by reliance upon a nuance of prior assessment, only too likely to have been optimistic.”
“If B realises (without agreeing to such conduct being used) that A may kill or intentionally inflict serious injury, but nevertheless continues to participate with A in the venture, that will amount to a sufficient mental element for B to be guilty of murder if A, with the requisite intent, kills in the course of the venture. As Professor Smith points out, B has in those circumstances lent himself to the enterprise and by so doing he has given assistance and encouragement to A in carrying out an enterprise which B realises may involve murder.”
“the wider principle [wider than joint enterprise or common purpose liability] whereby a secondary party is criminally liable for acts by the primary offender of a type which the former foresees but does not necessarily intend . . . .The criminal culpability lies in participating in the venture with that foresight.”
“Is it sufficient to found a conviction for murder for a secondary party to a killing to have realised that the primary party might kill with intent to do so or with intent to cause grievous bodily harm or must the secondary party have held such an intention himself?”
“Is it sufficient for murder that the secondary party intends or foresees that the primary party would or may act with intent to cause grievous bodily harm, if the lethal act carried out by the primary party is fundamentally different from the acts foreseen or intended by the secondary party?”
“It seems to this court that to say that adventurers are guilty of manslaughter when one of them has departed completely from the concerted action of the common design and has suddenly formed an intent to kill and has used a weapon and acted in a way which no party to that common design could suspect is something which would revolt the conscience of people today.”
“In a case of this kind it is difficult to imagine what would have been outside the scope of the concerted action, possibly the use of a loaded revolver, the presence of which was unknown to the other parties . . .”
“(a) to whether the killing was within the scope of a common purpose to which the secondary party was an accessory; (b) to whether the principal’s act was fundamentally different from the act or acts which the secondary party foresaw as part of the joint enterprise.”
“Trial judges have frequently based their directions to the jury in respect of the liability of a secondary party for an action carried out in a joint venture on the first passage [in Anderson and Morris , a passage pointing out that those engaged in a joint enterprise are liable for the acts done pursuant to it including liability for unusual consequences if they arise from the execution of the agreed joint enterprise, but not for the consequences of an unauthorised act if one of the adventurers goes beyond what has been tacitly agreed as part of the common enterprise]. There is clearly no error in doing so. However in many cases there would be no difference in result between applying the test stated in that passage and the test of foresight, and if there would be a difference the test of foresight is the proper one to apply. I consider that the test of foresight is a simpler and more practicable test for a jury to apply than the test of whether the act causing the death goes beyond what had been tacitly agreed as part of the joint enterprise. Therefore, in cases where an issue arises as to whether an action was within the scope of the joint venture, I would suggest that it might be preferable for a trial judge in charging a jury to base his direction on the test of foresight rather than on the test set out in the first passage in R v Anderson; R v Morris .”
“The issue . . . whether a secondary party who foresees the use of a gun to knee-cap, and death is then caused by the deliberate firing of the gun into the head or body of the victim, is guilty of murder is more debatable". But why, I wonder, is that merely “debatable"? Why is the secondary party in those circumstances not plainly guilty of murder, just as the appellants in Powell ? And if that be right, why should it make all the difference that in fact the victim’s death was caused by a knife? After all, as Lord Hutton said just a few paragraphs later (at p 30 F-G): “if the weapon used by the primary party is different to, but as dangerous as, the weapon which the secondary party contemplated he might use, the secondary party should not escape liability for murder because of the difference in the weapon, for example, if he foresaw that the primary party might use a gun to kill and the latter used a knife to kill, or vice-versa.”
