"Voong is, as the crown quite properly said to you, a self-confessed criminal, a person who is up to his neck in dealing in drugs and it would appear probably, from the evidence that you have heard, not just on this occasion either. Not a person of good character; by his own confession convicted of a serious offence. Also on his evidence he is an accomplice of Mr Foo in an enterprise of heroin possession and distribution from one to another.
It is traditional to warn juries of the dangers of the evidence of an accomplice because it's the long experience of the law - and it's not confined to the law, of course, by any means - that people try to blame others for their own wrongs; that accomplices have a number of motives in different cases not to tell the truth.
It seems to me that the risks inherent in Mr Voong's evidence have been put to you by Mr Hore-Lacy quite clearly, but let me remind you of them because it is important that you take them into account in evaluating Voong's evidence. As accomplices generally may, Mr Voong clearly may wish to minimise his own role: just following orders, just doing what Saiman said. There was Saiman at one end and Mr Foo at the other, and he just did this bit in the middle.
He may wish to have something to bargain with, hoping that the police and the courts will deal more leniently with him if he, if I can put it colloquially, dobs in someone else. The nature of the drug trade, where some participants you might think might be pretty scary people, is such that it might be easier for him to implicate someone who is a small player, or even wholly innocent, rather than those really directing him if he knows who they are, those really involved.
There is also, as was put to you, the effect of s 21E of the Crimes Act, which I won't bother to read out, but which basically is to the effect that if, after you have said you will cooperate and you have got a reduced sentence as a result, you then fail to do so, you can be brought back before a court which will make a decision about whether you did fail and then what should be done with you, probably by way of increasing your sentence if you haven't.
You can see it is perfectly proper for the police to invite cooperation. It is perfectly proper for Voong to get a reduced sentence for cooperation, but the problem for you for your deliberations is however proper all that is, you can see that a person in Voong's position may feel a lot of pressure to stick to a story once he has told it, so there are all those things that you have to take into account in relation to Voong's evidence.
Consider his evidence with great care for those reasons. You can accept it. That's for you; that's why he was here. He is a witness whose evidence you can accept if you wish but you must take those things into account; you must. You must consider them carefully in deciding whether you will accept it."
