The case submitted to the jury
21 From beginning to end, the crown put its case on manslaughter as one of joint criminal enterprise. Conformably, the trial judge summed up on that basis.
22 The trial judge provided the jury with written directions. This was not done until towards the end of the summing up. The summing up anticipated the written directions, but with some qualification to which we will refer.
23 In the written directions, which we will now quote in full, we have emphasised passages for later reference:
" DIRECTIONS IN RELATION TO EACH ACCUSED AND EACH VICTIM
MURDER - JOINT CRIMINAL ENTERPRISE
Elements :-
1. An understanding or arrangement amounting to an agreement came into existence between the particular accused and other persons to assault the particular victim, that is to apply physical force to the victim's body, and in the assault to inflict grievous bodily harm on the victim, that is really serious bodily injury.
2. In accordance with the agreement to assault the victim and to inflict grievous bodily harm on him and while the accused continued to be a party to the agreement, a party or parties to the agreement did an act or acts with intent to inflict grievous bodily harm that is to inflict really serious bodily injury, which in fact caused the death of the victim.

or

3. Although the inflicting of really serious bodily injury on the victim was not within the agreement, nevertheless the accused contemplated that, in the course of the carrying out of the agreement to assault the victim, a party or parties to the agreement might do an act or acts with intent to inflict really serious bodily injury on the victim, but nevertheless the accused, having that contemplation, continued to be a party to the agreement up to and including the time when the act or acts done, with intent to inflict grievous bodily harm and causing death were done.
4. The accused participated in some way in the joint criminal enterprise to assault the victim. It is sufficient for the Crown to prove that the accused participated in any of the following ways:-

If the jury are satisfied beyond reasonable doubt of all of the elements of murder-joint criminal enterprise or extended joint criminal enterprise, they should find the accused guilty of murder. If the jury are not satisfied beyond reasonable doubt of all of the elements of either murder-joint criminal enterprise or murder-extended joint criminal enterprise, they should find the particular accused not guilty of the murder of the particular victim and they should proceed to consider manslaughter.

If the jury are not satisfied beyond reasonable doubt of all of the elements of manslaughter, they should find the accused not guilty of manslaughter and should proceed to consider maliciously inflicting grievous bodily harm.
MALICIOUSLY INFLICTING GRIEVOUS BODILY HARM
Elements
1. An understanding or arrangement amounting to an agreement came into existence between the particular accused and other persons to assault the victim and to cause some injury to the victim.
2. In the course of the carrying out of the agreement to assault the victim and to cause some injury to him and while the accused continued to be a party to the agreement, a party or parties to the agreement did an act or acts in assaulting the victim with intent to cause some injury to the victim, which in fact caused grievous bodily harm, that is really serious bodily injury, to the victim.
3. The accused participated in some way in the joint criminal enterprise to assault the victim and to cause him some injury. It is sufficient for the Crown to prove that the accused participated in any one of the following ways:-
(i) The accused himself did an act or acts of assaulting with the intent to cause some injury, by way of participating in the assaulting of the victim.
(ii) At the time when the act or acts causing grievous bodily harm were done by some other party or parties to the agreement, the accused was present and knowing that that party or those parties intended to assault the victim and cause him some injury, intentionally assisted or encouraged that party or those parties to assault the victim and to cause him some injury
or
(iii) In the case of Mr Chai, he procured the party or parties to the agreement who did the act or acts causing really serious bodily harm, to assault the victim and cause the victim some injury.

If the jury are satisfied beyond reasonable doubt of all of the elements of maliciously inflicting grievous bodily harm, they should find the accused guilty of maliciously inflicting grievous bodily harm.
If the jury are not satisfied beyond reasonable doubt of all of the elements of maliciously inflicting grievous bodily harm, they should find the accused guilty of that charge."
24 The direction recorded in para 3(i) under the heading, "Murder-joint criminal enterprise" was withdrawn. That was because the crown did not assert that the jury should or could find that the appellant or Mr Bae had done the particular act or acts which caused death in relation to either of the deceased.
25 It may be noted that, in relation to the second basis for murder, the heading over that section included the words "Extended joint criminal enterprise". The section also included, as an element in the case to be proved, that the appellant contemplated an act or acts done with intent to inflict really serious injury. The other sections in the written directions - relating to the first basis for murder, and to manslaughter and maliciously inflict grievous bodily harm - did not carry those words in the respective headings, and did not include the element of contemplating an act or acts which had a character different from that agreed upon as the subject of the joint enterprise.
26 The trial judge's oral summing up concerning the elements in the crime of manslaughter, as those charges were left to the jury, was as follows (emphasis added):
"1. The first element is the same as the first element in the extended joint criminal enterprise way of establishing guilt of murder. The first element is that an understanding or arrangement amounting to an agreement came into existence between the particular accused you are considering and other persons to assault the victim. All that I said earlier about such an understanding or arrangement applies equally here. It is sufficient that the object of the agreement was merely to assault the victim. It is not necessary that the understanding or arrangement should have included the intentional infliction of grievous bodily harm.
