“In my judgment the jury could conclude that the events of that night amounted to one continuous criminal enterprise, albeit there was a short period of calm in the middle. On the evidence called thus far, the jury could conclude that Laura Mitchell was part of an enterprise to do violence to the two Powells and the deceased before the short period of calm. They may also conclude that her continuing presence on the car park whilst further violence was done, culminating in the death of Andrew Ayres, was not merely accidental and that her presence there was, and was intended to encourage others.”
“Now whether an individual participates in a particular joint enterprise is also a matter of fact for you to decide. If you are sure that a Defendant whose case you are considering did participate in a particular joint enterprise, ask yourselves for how long did he or she do so? In any criminal activity involving more than one person, people may join, but they may also leave or withdraw, in which event, they have no criminal liability for what occurs after their withdrawal. It is undoubtedly the case that the person who joins a common enterprise after the fatal injuries or injuries have been inflicted is not guilty of murder because he was not a party to the unlawful violence at the time when the fatal injuries or injuries were caused. In contrast, once a person becomes a party to a joint enterprise, he or she is still, in law, taken to be participating in it at the time when the fatal blows are inflicted by one of his associates, even though he or she himself, or herself, may have ceased any physical violence against any other member of the attack group unless he, without questions, withdraws from the joint enterprise before the moment when the fatal blow by his associate is struck. Let me give you a brief example. Suppose three men embark upon an unlawful joint enterprise to do violence to three others in the street. Each man attacks some members of the other group. The first attacker fells his victim with a single blow. He does no more violence to him, or anyone else, and stands around watching. The second attacker fells his victim with three blows. There is no more violence to him or anyone else and he stands around watching. It takes the third attacker a considerable number of blows to knock his man down and he then kicks him a number of times in the head causing his death. Even though the fatal kicks were inflicted after the first two men had ceased physical violence themselves, those first two are, certainly in the absence of clear evidence of withdrawal, still participating and accordingly are still potentially liable for the death of the third man. They are still part of a common enterprise even though their own physical acts have concluded. Whether or not they have withdrawn will depend upon a number of things, not least their state of minds as you will see in a moment, but, for the purposes of deciding if they are still participating, a quirk or accident of timing cannot, you may think, excuse them from being participants in the last fatal blow. So what do I mean by withdrawal? iii) He then specifically directed the jury on the meaning of withdrawal from the joint enterprise: “Well any participant in a joint enterprise can withdraw their support for it at any time and if they have done so effectively, then they will not be liable for anything done after that withdrawal takes effect. In the case of a pre-planned criminal enterprise, such as the example I gave you earlier – the four men who decide to shoot someone – if before the appointed day, one of them sent a text message to all the others saying that he had had second thoughts and did not wish to take any further part in what had been planned and would not carry out his allotted task on the fatal day, then if the other three carry on, and carry out the shooting, then the context of the text message would be extremely strong evidence, would it not, that the sender had in fact withdrawn from the joint enterprise. Now clearly in such an example, which is a pre-planned attack, communication between the participants may be easier to achieve and there may be far more time in which to achieve it. In the case of a spontaneous event, it may well be more difficult and the position is, in reality, a little different. However, a mere change of heart is not sufficient. Neither, as I have just said to you, is the fact that you have, for whatever reason, ceased to attack a member of the other group whilst one of the other parties from the joint enterprise continues to attack and to kill the deceased. There must be some steps taken by the individual to withdraw. He could, for instance, shout out to Holmes to stop or not to do it, or even to pull him away. In the context of a spontaneous outburst of violence, and with fast moving events, that may be difficult. You should not, in the cold light of day, seek to impose strict and rigid criteria to a sequence of events which happened very quickly and may require someone to act instantaneously at a time when he or she cannot be expected to work out exactly what he or she needs to do in order to withdraw from an unlawful joint enterprise. Someone in the position of Michael Hall, Laura Mitchell ([the appellant]) or Henry Ballantyne ([the applicant]) must do something to demonstrate that they are, or may be, withdrawing from any ongoing joint enterprise in which they had participated, or that they do not seek to take part in any new one before you could properly consider the matter. Let me give you an example. If a group of men, in a spontaneous joint enterprise of violence are chasing another man armed with weapons, bottles and sticks through the streets of a town, and at a point when the man being chased and the remaining chasers turn a corner out of the sight of the one of the attackers, and that one attacker then stops, puts down his weapon and walks back the way he had come, and does not go round the corner, he does not participate any further in the attack which culminates two streets later with the death of the man being chased. In such a case, a jury may well conclude that that one man, by stopping and acting as he did, had withdrawn from the joint enterprise of which he was at one stage a willing member. If is a question of fact and degree in every case.”
“that as stated by the High Court of Australia in McAuliffe v The Queen (1995) 69 AJLR 621 at 624 … ‘the scope of the common purpose is to be determined by what was contemplated by the parties sharing the purpose’. Therefore when two parties embark on a joint criminal enterprise one party will be liable for an act he contemplates may be carried out by the other party in the course of the enterprise even if he has not tacitly agreed to that act… and at page 21 There is therefore a strong line of authority that participation in a joint criminal enterprise with foresight or contemplation of an act as a possible incident of that enterprise is sufficient to impose criminal liability for that act carried out by another participant to that enterprise”
“Secondary participation consists in assisting or encouraging the principal offender in the commission of the crime. A party who withdraws from an enterprise, spontaneous or not, usually ceases to assist but he does not necessarily cease to encourage. Suppose that A is encouraged in the fight because he knows B is in there with him. If B decides he has had enough and quietly slopes off without attracting A’s attention, the external element of secondary participation still continues. B’s encouragement of A is still operative. Does mere withdrawal then relieve B of responsibility? In principle, it seems that it should not do so. A person who has done an act which makes him potentially liable for a crime cannot relieve himself of responsibility by a mere change of mind. Once the arrow is in the air, it is no use wishing to have never let it go – “Please God, let it miss!”
“Thus the Professor emphasises that it can only be in exceptional circumstances that a person can withdraw from a crime he has initiated. Similarly in those rare circumstances communication of withdrawal must be given in order to give the principal offenders the opportunity to desist rather than complete the crime. This must be so even in situations of spontaneous violence unless it is not practicable or reasonable so to communicate as in the exceptional circumstances pertaining in Mitchell where the accused threw down his weapon and moved away before the final and fatal blows were inflicted.” iii) In R v O’Flaherty, Mantell made clear at 64- 65: “64. Accordingly, we consider, as this Court did in R v Mitchell and King (1988) 163 JP 75 that the jury should have been directed that they must be satisfied (a) that the fatal injuries were sustained when the joint enterprise was continuing and that the defendant was still acting within that joint enterprise, and (b) that the acts which caused the death were within the scope of the joint enterprise. As far as (b) is concerned, we have concluded that the jury were appropriately directed in respect of the use of knives. In respect of (a), however, since the jury was only directed to consider the evidence as to the cause of death and what part the particular defendants played if they decided they were dealing with two separated events, we have concluded that the jury was not appropriately directed. The distinction made in the directions between whether there was one event or two meant the jury was not directed that even if they concluded the incident was one continuing evolving event, they had to be satisfied that the fatal injuries were sustained when the joint enterprise was continuing and that the particular defendant was still acting within that joint enterprise. 65. It is not arguable that the learned judge should have withdrawn the case of O’Flaherty from the jury. The fact that he followed the group to Park Street West still armed with the cricket bat provided an evidential foundation for the jury to conclude, if properly directed that he was “still in it”.”
