(1) A party who called a witness may, with the leave of the court, question the witness, as though the party were cross-examining the witness, about:
(a) evidence given by the witness that is unfavourable to the party, or
(b) a matter of which the witness may reasonably be supposed to have knowledge and about which it appears to the court the witness is not, in examination in chief, making a genuine attempt to give evidence, or
(c) whether the witness has, at any time, made a prior inconsistent statement.
(2) Questioning a witness under this section is taken to be cross-examination for the purposes of this Act (other than section 39).
(3) The party questioning the witness under this section may, with the leave of the court, question the witness about matters relevant only to the witness's credibility.
(4) Questioning under this section is to take place before the other parties cross-examine the witness, unless the court otherwise directs.
(5) If the court so directs, the order in which the parties question the witness is to be as the court directs.
(6) Without limiting the matters that the court may take into account in determining whether to give leave or a direction under this section, it is to take into account:
(a) whether the party gave notice at the earliest opportunity of his or her intention to seek leave, and
(b) the matters on which, and the extent to which, the witness has been, or is likely to be, questioned by another party.
(7) A party is subject to the same liability to be cross-examined under this section as any other witness if:
(a) a proceeding is being conducted in the name of the party by or on behalf of an insurer or other person, and
(b) the party is a witness in the proceeding. "
6 The Court of Criminal Appeal has upheld the grant of leave where the Crown deferred an application under s 38 until after cross examination by the defence: R v Parkes [2003] NSWCCA 12, 147 A Crim R 450. That is the situation in the present case. In Parkes the Court of Criminal Appeal held that there was no unfairness in the Crown deferring an application under s 38 until after cross-examination by the defence. The Crown Prosecutor knew that a witness called by the Crown was likely to give unfavourable evidence on a particular issue and deliberately refrained from asking about the unfavourable evidence. When that unfavourable evidence emerged in cross examination, the prosecutor made an application under s 38. It was argued that had the defendant known that a s 38 application was to be made after the witness cross-examination, the defendant would have conducted his case differently. However, counsel for the defendant did not suggest how the case could have been differently run and the Court of Criminal Appeal could not think of anything that counsel for the defendant might have done differently in any material way. Ipp JA (Hulme and Bell JJ agreeing) said at [81] - [85]:
"81 It may be argued that some unfairness lay in the fact that the Crown, by the procedure it adopted, obtained the best of both worlds, a result far removed from the situation that would have obtained under traditional adversarial processes. But s 38 does have the potential for transforming the traditional procedure; this lies at the very heart of the section. Accordingly, it seems to me, the mere fact that this actually occurred and the Crown was allowed to cross-examine on evidence brought out in cross-examination by the defendant, startling as it may seem to those brought up on more old-fashioned ways, is not enough to constitute unfair manipulation.
82 Then, it must be asked whether that there was abuse of the section, and resulting impropriety or unfairness to the appellant, because the Crown made a deliberate decision not to question Harris about the three issues (and the number of invoices, in particular) and made a deliberate decision to take its chances in applying under s 38 after Harris had been cross-examined.
83 Unfairness to the appellant, as I have previously indicated, has to be judged in the context of the legislation. I see nothing in the section that prohibits, expressly or impliedly, the course that the Crown adopted. What in fact occurred was that the Crown was allowed to cross-examine Harris and water down the effect of the evidence he had given. There was nothing unfair in the cross-examination. The result was that a truer picture of the situation was presented to the jury than would have been the case had the Crown been refused leave to cross-examine. This is the very purpose underlying s 38. It was not contended for the appellant that any kind of unfairness resulted from the procedure adopted, other than that referred to in paragraph 81 above,
84 The decisions taken by the Crown were based on reasonable grounds; that is to say, the situation that the Crown faced in regard to Harris was such that it was reasonable, forensically, for it to wait to see whether Harris would give unfavourable evidence in cross-examination and then to apply under s 38. The point being that it was completely uncertain, as far as the Crown was concerned, whether or not Harris would be asked about the three issues and what replies he would give (although the Crown knew that there was a potential for some or all of the replies to be unfavourable). I see nothing improper in the Crown adopting the procedure that it did.
85 Accordingly, I have come to the conclusion that, although the deliberate decisions taken by the Crown have to be classified as falling into the basket of forensic tactics, they did not lead to the Crown's application under s 38 being an abuse of the section."
7 That approach was endorsed by the Court of Criminal Appeal in Burrell v R [2007] NSWCCA 65 at [246].
8 Section 38(4) appears to suggests that an application such as this should ordinarily be made during the course of the evidence-in-chief of the witness for it provides that questioning under that section is to take place before the other parties cross-examine the witness, unless the court otherwise directs. Uninstructed by authority, I would have thought that exceptional circumstances would be required before the Court would give a s 38(4) direction. However, the authorities seem to encourage a liberal approach even where the application is made after cross-examination is concluded. They suggest that s 38 brings about a change to the pre-existing law to an extent which, as Ipp JA said in Parkes, may seem startling to some.
