Consideration of relevant factors
17 The proceedings are broadly of a similar nature, and there are common issues of fact, and probably law, in the proceedings. At the same time, not all issues are common issues and it is difficult to be precise as to the degree of commonality. Furthermore, some weight must be given to the respondents' submission that a number of common issues such as the facts relating to newsletters, the scale model and the brochure will not be in dispute.
18 It is appropriate to proceed on the basis that there will be witnesses called by the applicants who will be common to each proceeding. The valuer and town planner fall into this category. There was a good deal of debate before me about whether an applicant in one proceeding could give evidence in another applicant's proceeding. Counsel for the respondents referred to the general section in the Evidence Act 1995 (Cth) s 56 (evidence that is relevant is admissible) and s 97 (evidence that a person had, or has, a tendency) and s 98 (evidence making it improbable that events occurred coincidentally). Counsel for the applicants submitted that an applicant would not be called in another applicant's proceeding to prove tendency or improbability of coincidence. He submitted that the evidence of an applicant in another applicant's proceeding would be relevant to the first and second respondent's state of mind. Clearly, it is not for me to rule on this point at this stage. However, on the submissions made to me on the applications, it is not apparent to me how the evidence of an applicant in one proceeding will be relevant and admissible in another applicant's proceeding.
19 I have no information about the witnesses the vendor respondents are likely to call. It is fair to proceed on the basis that there are likely to be some witnesses called by the vendor respondents who will be common to some or all of the proceedings.
20 There are three sets of real estate agents who are respondents. Clearly, their evidence will not be common to all the proceedings.
21 There have been two attempts to have in effect a "lead case" and both have failed because the case selected has settled. There is no agreement between the parties to abide the outcome of a test case, or to be bound by the findings and conclusions with respect to common questions of fact and law. Having said that, I think it is likely that parties in later trials will not contest findings made in earlier trials unless they have further or different evidence not called at the earlier trials.
22 There is the prospect of multiple appeals, even if the proceedings are tried at the same time. However, if the proceedings are tried at the same time, any appeals are likely to be heard at the one time rather than at different times, which may well be the case if the proceedings are heard separately and at different times.
23 There is likely to be a saving of time if the proceedings are tried together, but it is difficult to quantify the extent of the saving. It would be nowhere near the substantial saving referred to in Fox v Olsen [1999] SASC 411 at [7] per Mullighan J (with whom Doyle CJ and Wicks J agreed). It seems to me that 2 weeks is a reasonable estimate for the trial of the proceeding brought by Mr Humphries. It is difficult to be precise about an estimate of trial time if all proceedings are tried at the same time, but, doing the best I can, I proceed on the basis of an estimate of 4-8 weeks. If tried separately, the proceedings involving Mr Humphries would, as I have said, take 2 weeks and the other 7 proceedings would take 1-2 weeks each. There is a real prospect that the parties in those 7 proceedings would not contest a number of findings of fact made in the first proceeding and therefore, if they did proceed, the estimate for each proceeding would be closer to 1 week than to 2 weeks.
24 Trial management issues are likely to loom large if all proceedings are tried together. It would be necessary to put in place detailed and possibly complex procedural orders to ensure the trial proceeded in an orderly fashion. There is considerable potential for time-consuming arguments about the cross-admissibility of evidence. Counsel would need to be alert to the evidence rulings about cross-admissibility. These problems are by no means insurmountable, but they are a reason not to order that the proceedings be tried together.
25 The proceeding involving Mr Humphries is further advanced, in terms of preparation for trial, than any of the other proceedings.
26 There are three sets of agents and each of them will not be interested in evidence which does not concern them. They will be inconvenienced to some extent although, no doubt, they could be given leave to withdraw from the trial while evidence which does not concern them is being given.
27 I have to weigh up these factors and determine where the balance lies. Some of the matters cannot be precisely weighed because they are matters where impression takes the place of precise finding. In the result, although I think there is a good deal to be said for an order that the proceedings be tried together, I think the most important consideration is firmly against such an order. It seems to me that there are likely to be considerable difficulties in terms of procedural rulings and rulings on evidence (in particular, rulings as to the cross-admissibility of evidence), if the proceedings are tried at the same time.
28 An order that the eight proceedings be tried at the same time should not be made.
