In the case of Mr Zerna, you heard cross-examination of various witnesses. Now, there is a rule which, in layman's terms, might be called "The rule of challenge about the way in which criminal trials are run". And you might think it's a rule of common sense. The essence of that rule is if you are going to end up putting to the jury something which is contradictory to a witness' evidence, you must, in the course of cross-examination, clearly identify for that witness that that fact is in issue. If you don't do that, you, ladies and gentlemen, are entitled to take into account the failure to do that in assessing whether or not you hear a submission about a matter which you now hear for the first time after I sit down.
Counsel conducting cross-examination of a witness is bound by a rule of law and practice that he must challenge the witness as to any matter of fact or inference which is inconsistent with the evidence of the witness on which the Crown is relying. Now, that process is essential to a jury's understanding of what facts are truly in issue. They are essential for you to enable you to assess the witness' credibility in relation to those issues. You are entitled to, as I said, take into account any failure to comply with that rule in determining whether or not you accept something which comes out of the blue after I sit down.
For instance, let me just put this into some perspective in the case of Mr Zerna. You heard me open that [PTO] would give evidence that in July of 2005 he had lunch with Zerna and Johnson. Now, if Johnson doesn't know anything about this what's Zerna doing taking him to the lunch but in any event. He has lunch with Zerna and Johnson. In the course of that lunch numerous things which are consistent with a conspiracy to manufacture methylamphetamine are discussed. When I opened to you I think I said something along the lines of, "I don't know whether this is in issue or not". When Mr Barker opened to you - nothing said, nothing said, not a word said about what you might think is a critical piece of evidence in respect of his client, not a word. [PTO] gets into the witness box, he gives evidence about that lunch. Is he challenged to any extent? Is it suggested to him it didn't happen or something that he says was said at that luncheon wasn't said? No. And so what I say to you, ladies and gentlemen, as a result of that there is no logical basis - I mean, it's a matter for you - but there's no logical basis on which you could fairly come to the conclusion that that lunch did not take place precisely as [PTO] said it did. And if that is now - you see, what's happened, and I will take you to this in just a minute because I will be going to [PTO's] evidence, but the cross-examination of [PTO] was almost exclusively challenging his credibility in respect of his role as an informer, who he dobbed in, who he didn't dob in, he's an alcoholic, he's had mental health problems. That's all very well but that would assist you, perhaps, if there was some issue in this case which was identified for him, where it's said to [PTO], "Look, [PTO], because you're a drunk and because you're a liar and a crook and because you denied something at the committal which you shouldn't have denied, what I am suggesting to you is that this happened at all". Did that ever happen? Not once, not once. So if it is suggested now that you should not believe [PTO] about something he says about this case, you ask yourselves, "Well, if that's being suggested to me why wasn't it put to [PTO]?" And you would be entitled to conclude that the reason it wasn't put was because [PTO] would have hit any such suggestion to six because, as it turns out, despite the problems he's had the past, he presented as a witness who had quite a remarkable ability to recall facts and to assemble information.
You will recall that [PTO] gets into the witness box, he gives evidence. The first piece of evidence he gives is about that list, the list he got at the end of October or early November which the Crown says is a list of chemicals required for the manufacture of methylamphetamine. Now, Mr Johnson, who was in fact the person who has provided the list, he makes no challenge to anything that [PTO] says. What happens when he's cross-examined? You had him cross-examined along the lines of, "Well, look, did Roth give you a list? Are you sure that Roth never gave you?" He said, "No, I'm absolutely adamant Roth never gave me a list". If it is now said to you, "Perhaps that list came from Roth", ladies and gentlemen you would say, if you accept the propositions that I have been putting to you, "Well, how could I accept that when you didn't ever put to [PTO] that that list came from anywhere else other than where you said it came from?"
You can't just fiddle around the edges in the hope to stand up after the prosecution has closed, you have to put your cards on the table in order to allow the processes to take place which allow us to analyse the merit of some proposition which is capable of being the subject of examination or re-examination to be properly assessed by a jury and if you don't do that, the jury, I would suggest to you, are entitled to conclude that the reason that wasn't done was because it would have brought about a counter-productive response.
