32 I consider this can be done in this case. The trial judge can make appropriate directions and deal with the prosecutions according to the evidence so as to avoid prejudice to Mr Coomes and ensure that Mr Coomes is given a fair trial.
33 I do not consider the fact that Mr Coomes is a project manager and not a director of the corporation, to be material. The circumstances in which joint trials are appropriate are not closed. The fact that in the past there may have been joint trials between a corporation and directors of the corporation does not exhaust the circumstances where it is appropriate to have a joint trial. By reason of the commonality of the facts and the evidence, it is appropriate that there be a joint trial of each of the defendants in this case.
34 There may be some additional legal costs incurred by Mr Coomes by reason of having a joint trial. At the outset, it should be noted that this is always the case where there is a joint trial. The very nature of a joint trial is that there are more than one defendant. The presence of the other defendants will always lead to some additional legal costs associated with extra cross-examination or extra submissions. However, the advantages of having a joint trial, referred to in the cases to which I have already made reference, outweigh this additional legal cost being incurred by a defendant.
35 In any event, in the circumstances of this case, I do not consider that the additional legal costs that might be incurred by Mr Coomes by having a joint trial, would be disproportionate or would be so great as to work unfairness or injustice to Mr Coomes. All of the witnesses the prosecutor has given notice that it wishes to call would still be called regardless of whether there is a joint trial or there are separate trials. The records of interview would of course be tendered, although only against the particular defendant who is the subject of the record of interview, but the tender of these records of interview would not take any material time. There would be some extra cross-examination and additional submissions by reason of the defendants all being there. However I do not consider this would be unreasonable.
36 I also note that any additional time in cross-examination or submissions, caused by having multiple defendants in a joint trial, does not necessarily lead to prejudice to the defendant. Of course it is true, as Mr Coomes submitted, that there is a degree of uncertainty as to what might transpire in a joint trial. Nevertheless, there can be advantages to defendants in having a joint trial. This was noted in R v Jones at [27] where Justice Buddin noted that:
"… the applicant could actually benefit from a joint trial because she would be able to take advantage of any evidence adduced at it which casts doubt upon the Crown's capacity to establish the principal offence. This may prove to be more difficult for her at a separate trial where, of necessity, the principal parties (and their representatives) will not be able to assist in facilitating such an outcome".
37 In this case, there are a number of different elements for each of the offences that would need to be established. The matter concerning who is responsible for directing Mr Hanger to carry out the works of removal of snags and woody debris, is one of those elements. It is in relation to this matter that Mr Coomes has expressed concern about the records of interview but there are a number of other elements that would need to be established. It may well be that any advantage the defendants in the other proceedings might gain in casting doubt upon the prosecutor's case on those other elements, would be beneficial to Mr Coomes in similarly casting doubt on the prosecutor's case in respect to those elements for the same offences against Mr Coomes. Of course this may not come to pass but I simply note that it cannot be assumed that having a joint trial always and necessarily leads to prejudice; it can sometimes lead to an advantage to a defendant.
38 Balanced against the additional legal costs that might be incurred by Mr Coomes by reason of a joint trial are the savings that would be achieved by having a joint trial. The conserving of costs, improving the efficient dispatch of trials and avoiding inconvenience to witnesses by having to attend a number of trials are factors that have been referred to in the various authorities.
39 These factors are particularly applicable in this case where, as I have said, the prosecutor will call each and every one of its witnesses in a separate trial just as it would in a joint trial. Hence, if there were not to be a joint trial, there would be a wholesale duplication of all of the evidence of the prosecutor and each of those witnesses that I have set out earlier in my reasons for judgment would need to be called again. It is not only Mr Hanger who would need to attend the two trials. Nevertheless this concern is particularly relevant to Mr Hanger because he comes from Melbourne and his evidence is critical in the case against the defendants and it is likely that he would need to be cross-examined for a considerable period of time.
40 It has also been noted in the authorities that there is an advantage in having a joint trial where there is likely to be cutthroat defences, that is where each of the defendants deny they were responsible but will be alleging that other defendants were responsible. This factor has been referred to in the authorities as tending towards establishing that a joint trial would be beneficial, see for example R v Demirok at 251- 253 as well as Webb and Hay v The Queen (1994) 181 CLR 41 at 88-89 quoted in R v Fernando at [211].
41 I have found the risk of unfair trial to Mr Coomes is not real and that what risk might remain cannot in the circumstances outweigh the other factors that tend to establish the desirability of having a joint trial.
42 In these circumstances, I consider it is appropriate to make the orders sought by the prosecutor.
