Accused
12During the hearing of the application, Mr Wendler varied the basis of the application to one of an abuse of process which he submitted should be stayed in accordance with his earlier submission that an issue estoppel arose. During the course of submissions there was an examination of the authorities - see below - where the existence of a doctrine of issue estoppel in criminal proceedings was doubted.
13The accused submits that these proceedings are oppressive, and that the Director, by proceeding with this indictment is simply investigating a controversy which has been finalised. Fundamental to this submission is that the controversy has been fully ventilated and examined in the earlier trial and that issues relevant to issue estoppel and abuse of process are relevant in the exercise of my discretion in this case.
14Mr Wendler submits that the jury's verdict in the earlier trial must be taken to have been a clear indication of the jury's determination of the issue of credibility between Mr Tasich and the principal Crown witness, Mr Coyte. He submits that the two witnesses were the only witnesses of substance and that the jury must be taken to have disbelieved Mr Coyte. The commonality of the evidence is said to be that the accused told ICAC that Mr Coyte had sought a corrupt benefit from the accused and that evidence was repeated in the trial. Further, that both Ms Hay (relevantly to the second count) and Mr Gigliotti (relevantly to the third count) gave evidence in the earlier trial and that the jury implicitly accepted Mr Tasich's account. It is submitted that the jury made an assessment of the totality of the evidence including the evidence concerning the allegations said to have been made to Ms Hay and Mr Gigliotti.
15Mr Wendler further submits that the jury's findings on credit - even if inferential - have "merged into the verdict" such that there is an issue estoppel. In the alternative, he submits that the verdict gives rise to a requirement that the proceedings be stayed. Further, that there was, by the earlier trial, a settlement of the issues - namely, adversely as to Mr Coyte's credit - such that his evidence cannot be relied on in the prosecution of the current indictment. He submits that the relevant witnesses were called in the earlier proceedings; further, that the judge in that earlier trial summed up on the relevant areas of evidence and the conflicts between Mr Tasich and Mr Coyte, leading to the inference that the jury must have considered and determined those issues.
16I have asked Mr Wendler for authority to support his essential proposition, namely, that a finding of credibility of a witness in relation to a Crown witness can be established from an earlier jury verdict such as to mean that the Crown cannot rely on that same witness in separate proceedings involving separate and distinct charges and different events.
17Mr Wendler has referred me to Gilham v R [2007] NSWCCA 323; (2007) 73 NSWLR 308 at [8] ff. In particular, he refers me to a passage quoted there from Island Maritime Ltd v Filipowski [2006] HCA 30; (2006) 226 CLR 328 at [43] to the effect that the principle is one of autrefois acquit, namely, that the Crown is estopped from re-asserting the guilt of the accused when that question has previously been asserted - and determined - against the Crown.
