There follows a number of exceptions including cross-examination as to credibility (s 103) and re-establishing credibility (s 108).
22 It has often been considered good advocacy for counsel who has a problem witness to confront the problem head-on as early as possible, and if there are going to be questions raised about previous inconsistent statements, to lead evidence as to the reasons or excuses for such inconsistent statements during the evidence in chief, rather than wait for an attack to be made on the witness in cross-examination. However, it would appear that such evidence, strictly speaking, would not be admissible in evidence in chief at common law, and that the position would appear to be reinforced by the provisions of the Act.
23 Credibility of a witness is defined in the Dictionary as meaning, "the credibility of any part or all of the evidence of a witness..." Although in my experience such evidence has in the past not infrequently been led in these circumstances, the words of the section appear to be clear, and this view is confirmed by the learned authors of Cross on Evidence, Australian edition at para [19005] who state:
"The Cth Evidence Act 1995 and NSW Evidence Act 1995 provide that evidence that is relevant only to a witness's credibility is not admissible: s 102. There are exceptions for cross-examination (ss 103-104), for rebuttal of certain denials by a witness (106) and for evidence re-establishing credibility (s 108), but there are no exceptions in relation to evidence in chief, save s110(1) permits an accused person who is testifying to give evidence of good character."
24 The evidence to which objection is taken falls squarely within the definition and therefore cannot be led except pursuant to the exceptions referred to. Mr Nicholson SC referred to the need for leave under s 108(3) to lead such evidence, even in re-examination; but s 108(1) is in my view quite separate from s 108(3) and if the credit of a witness is attacked, evidence from that witness relating to his credit is admissible in re-examination under s 108(1) without leave.
25 The Crown referred me to the judgment of McHugh J in Palmer v The Queen (1998) 151 ALR 616, but that case is distinguishable for two main reasons: firstly, the case was not concerned with leading evidence relating to credibility as evidence in chief but with the cross-examination of an accused as to whether a complainant in the sexual assault case had a motive to lie or fabricate allegations, and secondly, the discussion by his Honour concerning the distinction between evidence relating to facts in issue and evidence only going to credibility was concerned mainly with the finality rule by which other evidence cannot be led to contradict evidence going only to issues of credit, and was concerned with the difficulty in defining the boundary between the two. In any event, his Honour dissented on the relevant issues in the case, and his comments are only dicta.
26 I am therefore satisfied that the two witnesses can give evidence in chief that they were charged and at a later stage went to the authorities and were later given indemnities or undertakings but their reasons or motives for going to the police and their previous inconsistent or incomplete statements cannot, or their reasons for such discrepancies cannot, be led as part of their evidence in chief but only in re-examination, provided the anticipated attack on their credit is made.
27 The learned Crown Prosecutor therefore then submits that he would seek to refer to these matters in his opening address. Mr Nicholson SC, supported by Mr Cusack SC for the accused Dao, objects and submits that they are not proper matters for an opening and will take away the "thunder" of the defence attack. I can see no valid objection to the course proposed by the Crown. The object of the opening is to outline the Crown case to the jury so that they will understand the Crown case as individual witnesses are called.
28 It is clearly proper for the Crown to tell the jury that they are alleged accomplices, that the jury will be warned that their evidence may be unreliable and the reasons why it may be unreliable in that context. I cannot see any reason why the Crown cannot say that their credibility will be attacked and that one of the anticipated grounds of the attack will be that initially they only told the authorities part of their current evidence, but that they will give reasons for that and for later going further and what those reasons were.
29 Evidence intended to be led by the Crown in re-examination (to rebut a telegraphed attack on the credibility of an intended witness) is just as much evidence to be led by the Crown as evidence intended to be led from the witnesses in chief. There is no principle of which I am aware, and I have not been referred to any authority, to the effect that the defence is entitled to the tactical advantage or "thunder" of first raising the issue of credibility of a witness. The issue of their credibility will be raised by the need for a warning concerning their evidence under s 165, and the evidence will all be before the jury at some stage. However I am also satisfied that the Crown should deal with these matters only in general terms and not proceed too far into the specifics of the differences in the various statements, but merely that there were differences, and it is anticipated that they will give explanations for such discrepancies in due course.
30 The seventh objection relates to the Crown allegedly making continual requests for the non-publication orders in the presence of the jury. The matter has been resolved and the Crown has indicated that he will make such applications in the absence of the jury.
31 The eighth objection is to the Crown making any reference in its opening or in evidence in chief to Lucy Wang which seems to seeks to impute her credit insofar as her initial observations of the motor vehicle used by the gunman to escape the scene.
32 I am informed that Lucy Wang will give evidence that the deceased's assailant got into the front seat of a dark green car. TVT says that he was a passenger in the vehicle and that the assailant, whom he identifies as the accused Dinh, got into the near side rear seat. The objection apparently is to Ms Wang saying that she thought he got into the front seat, when her evidence will be that he got into the front passenger seat. Apparently the front near side door of Dao's car did not work, and so he could not have got into the front passenger seat, if it was Dao's car, as alleged.
33 The other objection is to the Crown proffering a suggestion as to why she might have got it wrong, such as shock, et cetera.
34 I must say this all seems rather trivial and nitpicking to me but defence counsel assure me that it is of "crucial importance". The Crown has indicated that he will not open to the jury that she "thought" that the assailant got into the front seat, and will not proffer a comment as to how she may have been affected by shock, although of course he reserves the right in his closing address to make any comments properly available to him in the light of the evidence at that stage.
35 The ninth objection is to the Crown relying on any evidence from TDN or TVT of any activities or conversation which is not in furtherance of the alleged joint enterprise between them and Phuong Canh Ngo. As a general proposition this objection is clearly valid, but the objection is taken to specific pieces of the evidence which is claimed do not come within the furtherance of the alleged joint enterprise.
36 The first piece of evidence objected to is summarised at p 51 of the transcript of this hearing and relates to evidence from the witness TDN of a nocturnal visit to his premises, so it is said, by the accused Ngo, who takes TDN from his bed and drives him to the vicinity of the Mekong Club where TDN is requested to remain in the car whilst Ngo speaks to Dinh and TVT some distance away from the car, they both being employees of the Mekong Club. At the conclusion of that conversation Ngo returns to the car and returns the witness TDN to his home.
37 This is evidence of association between some of those allegedly involved in the common purpose, and it is also evidence that TDN was prepared to do Ngo's bidding, to get out of bed and to sit in a car and then go home, all as directed by Ngo and for no apparent purpose.
38 It was submitted that there may be an innocent explanation for it all and that may be so; but prima facie it is unusual conduct on the part of both Ngo and TDN. There is no evidence that Dinh was involved in the common purpose at that stage. I am satisfied that the evidence is admissible against Ngo and Dao, and Dinh is entitled to have the jury warned that there is no evidence of his involvement in any common purpose at that stage.
39 The next objection relates to evidence from TVT and TDN of a conversation, or possibly two conversations between them, when each of them says to the other words to the effect that Ngo had asked him to kill John Newman (or to kill someone). Mr Nicholson SC concedes that each of them may give evidence of the conversation in which Ngo made the request to the witness, but submits that they cannot give evidence that they told each other of the request.
40 This meeting, or these meetings, were when they discussed getting a gun, and he rightly concedes that that part of the conversation is in alleged furtherance of the common purpose but he submits that this reference to Ngo's request is not, and cannot be, in furtherance of the common purpose, but is merely narrative of what has already occurred.
41 TDN's version of the conversation is set out in the current transcript at p 61.
42 True it is neither of them expressly says that the reason he wants to get a gun is because Ngo has asked him to kill someone, but in the context of the conversation the implication is at least open, if not irresistible, that the reason that he wanted a gun was to help Ngo kill John Newman; and other evidence shows that the gun or guns, when purchased, were passed on to Ngo, and the Crown claims that one of the guns purchased by these two accomplices, or either of them (it does not matter for present purposes) was in fact the murder weapon.
43 Both the witnesses were working for Ngo, both were involved in the common purpose with him, but this is the first time, as I understand the Crown case, that they came together to join in the common purpose with each other, the reference to Ngo's request was part of the process of them sounding each other out, and the passage objected to identifies the common purpose in which they joined with each other, namely to help Ngo kill John Newman.
44 People do not seek to buy guns for no reason and this conversation in its context identifies the reason why they wanted to buy the guns. Stripped to its bare essentials the conversation amounts to this,
A says B wants me to help him kill X. A says do you know where I can get a gun?
