The competing submissions
32 I have addressed above certain of the submissions of Mr Harvey which go to the perceived weaknesses of the plaintiffs' case. It seems to me that those submissions cannot be determinative of the outcome of this application.
33 Mr Harvey went on however to submit that even if the evidence introduced by the plaintiffs at trial provides a basis for cogent argument on matters of fact, the determination of issues as to liability "untrammelled by damages issues is likely to, at the very least, lower the real forensic issues considerably".
34 In considering this submission and the application brought by the defendant generally it is essential to determine if there can be an effective and appropriate severance of the case on liability and the case on damages.
35 In submitting that there can be an effective and useful severance Mr Harvey argued that the evidence on damages relied upon by the plaintiff is to be found in the report of Mr Cowell, an expert agronomist. That report is in evidence before me as Exhibit JG5 to the affidavit of Ms Graham. It is submitted that Mr Cowell's report confirms that there is no significant overlap between liability and damages. This submission calls for a close review of Mr Cowell's report.
36 As to liability, Mr Harvey submitted that the focus is on the defendant's conduct whereas the focus for the issue of damages is on the practices and economics of cotton growing. There are, he submitted, no readily identifiable intertwined issues of fact and law such as would render a separate trial on the issue of liability inappropriate.
37 Moreover, the issues on damages are complex and can be expected to occupy a considerable period of court sitting time. Mr Harvey referred to an estimate given by Mr King at an earlier point of time in this litigation that damages would take five days of hearing time. (I observe that Mr King was more optimistic on this application, asserting the hearing as to damages would take only 1 day, but this revised estimate seems to me to be unduly optimistic.)
38 A letter from the defendants' solicitor to the plaintiffs' solicitor dated 22 June 2010, Exhibit D to the affidavit of Bruce Cantrill sworn 28 June 2010, advanced considerations as to why there ought to be a severance of the liability issue and Mr Harvey adopted the expression of these perceived advantages in his submissions. The advantages as stated were these:
"if the defendants are successful on liability then clearly no damages issues would have to be determined, thus shortening the length of the proceedings by about 50%
substantial savings in relation to costs would thus eventuate for all parties
the resources of the parties would be directed towards the liability part of the case, untrammelled by damages issues
the Court could determine issues of liability in a factually confined case unimpeded by the weight of detail of expert damages evidence. This would substantially lessen the burden of the trial Judge
if it becomes necessary to consider damages issue, these issues could be more clearly and directly considered in the light of the liability findings. Expert evidence could be corrected to take into account the factual evidence findings; the court's time will be used more efficiently if liability is determined and, in accordance with those findings, the experts on quantum are able to agree on the methodology for the calculation of heads of damages
should the determination on liability favour the plaintiffs, it may be appropriate for the quantum issues to be referred out to a suitable referee."
39 Mr King submitted that the application for a separate trial of the issue of liability ought not be granted because the defendants by their conduct have put the plaintiffs to considerable costs in preparing for trial on damages. This is because on their application the Registrar made directions on 30 November 2009 requiring that the plaintiffs file and serve their evidence on damages by 26 March 2010 and file and serve their evidentiary statements by that date. The defendants waited for these directions to be addressed before filing the notice of motion presently before the Court on 29 June 2010.
40 The sequence of events to which this submission attracts attention does not persuade me that because the plaintiffs have incurred expense on the issue of damages pursuant to the Court's directions this ought to bar the present application.
41 Mr King next submitted that when the evidence of the plaintiff and the evidence of Mr Cowell is considered it becomes apparent that there is an interlocking of the evidence on liability and of damages. Further, he submitted, the credit of the plaintiff is going to be very much in issue in this case both as to the issue of liability and as to the issue of damages. The opinions of Mr Cowell as expressed in his report depend on the acceptance of assumptions as to the facts and those assumptions are largely based upon what the plaintiff has told him.
42 Consideration of these submissions advanced by Mr King warrants close attention to the statement of the plaintiff to which I have previously referred and also close attention to the report of Mr Cowell.
43 I am satisfied by, upon reflection on the issues arising under the amended statement of claim and upon reading the plaintiffs' statement that it is highly likely that the credit of the plaintiff will become an issue on this trial. I consider it likely that the first plaintiff's credit will be an important consideration not only as to the issue of liability but also as to the issue of damages.
44 As to liability the plaintiff's evidence will be of central importance to proof of each of the causes of action pleaded.
45 Turning to the issue of damages, it seems to me that the first plaintiff's evidence will also be of central importance.
46 As asserted in the amended statement of claim and in the first plaintiff's affidavit, the plaintiffs' case is that had the dam been constructed at the time the first plaintiff planned for it to be constructed it would have had favourable consequences for the growing season 2000 to 2001, and seasons subsequent to that. Because of the time it took for the necessary approval to be obtained, and by the time it would have been open to him to construct the dam, the circumstances had changed. It was no longer economically sound to go ahead and his evidence was that even if he had been able to have the dam built prior to January 2004 he could have harvested 4,000 mega-litres of water in January 2004 when there was a flood in the Moree Shire Plains area (paragraph 153). In paragraphs 168 to 173 of his affidavit the first plaintiff set out the reasons for his decision to build the dam which reasons underlie the claim for economic loss. The first plaintiff's affidavit addresses construction costs of the contemplated dam and his financial capacity to build it. The plaintiff's evidence would be directed to rainfall for the period 2000 to 2006. It is to be acknowledged that public records only go so far and that rainfall can vary significantly from one property to another. Evidence that the first plaintiff could give as to rainfall would be very important to his case.
47 As paragraph 187 to 201 of the affidavit disclose, the first plaintiff would expect to give evidence of much importance to his case as to the opportunities for cotton production which on his case were lost and his evidence would be important to quantify the cotton production claimed to be lost.
48 The first plaintiff could also be expected to give the relevant evidence as to the legal costs incurred in the proceedings brought against him, although his costs could probably be established other than through the evidence of the plaintiff and I do not consider it likely that any evidence he could give on this issue would be of central importance.
49 Turning to the evidence that Mr Cowell might be expected to give, as indicated by his report, Exhibit BRC1, it is evident that the report and the opinions expressed in it are based upon assumptions. Those assumptions are set out in section 2 to the report: 2.1 to 2.12. These are assumptions; the factual basis for them will depend to a significant extent upon evidence the first plaintiff could be expected to give.
50 Mr Cowell deals in paragraphs 2.13 to 2.15 with the construction costs for the dam and the matters set out as to construction costs are dependant upon the first plaintiff to establish the facts.
51 Mr Cowell deals with the rainfall from 2000 to 2006 in his report at 2.16 to 2.23 and as to this the evidence that Mr Cowell can give is to be married to the evidence that the first plaintiff can give.
52 Mr Cowell's report deals with cotton production and the infrastructure of costs at 2.24 to 2.38. A reading of this section of Mr Cowell's report again discloses that the first plaintiff's evidence will assume importance on this topic.
53 When one considers the matters addressed under the heading "Background of claim" in paragraphs 3.1 to 3.19 once again the first plaintiff's evidence will assume importance in complementing the evidence Mr Cowell may be expected to give.
54 Mr Cowell's report gives details concerning the properties Hazeldene and Rosewood West at section 6 of the report. The first plaintiff would have relevant evidence to give directed to the proof of the matters in this section. Similarly as to section 7 of the report headed "Water pumping opportunities".
55 In section 8 "Details of actual and potential Tarpaulin Creek pumping events", the first plaintiff's diary notes are identified as a source of matters set out and it is to be anticipated that the first plaintiff would be in a position to give relevant evidence as to the matters raised in this section of the expert's evidence.
56 Section 9 of the report is headed "Irrigation water allocations". I do not perceive this to be a section of the report which would depend to any real extent on evidence that the first plaintiff could give.
57 Section 10 of the report deals with "Actual cotton planting 2000 to 2001 - 2006 to 2007 seasons". It is to be expected that the first plaintiff would be in a position to give relevant evidence as to the matters here addressed in section 10.2.4. Mr Cowell expressly acknowledges reliance on information supplied by the first plaintiff that there was additional water left over at the time indicated.
58 Section 11 of the report addresses "Water supplementation" data, and "yield data incrementation" for the growing seasons 2000 to 2001, through to 2006 to 2007. The first plaintiff could be expected to give relevant evidence here although there are other sources disclosed as underpinning the expert's assumptions.
59 Mr Cowell's report in section 13 addresses "Determination of input costs" and section 14 addresses "Calculation of loss". I do not anticipate that the plaintiff would be required to give central evidence to the matters addressed in these sections.
60 It is to be noted that in his conclusions, Mr Cowell calculated a net potential loss of profit for the years addressed because of the lack of the contemplated dam in a figure in excess of $5 million dollars inclusive of interest.
61 Having considered the way the plaintiffs' claim has been pleaded, and having considered the affidavit of the first plaintiff and the report of Mr Cowell, I have come to the conclusion as indicated above that the first plaintiff is likely to give evidence of very real importance both as to liability and as to damages. This being so it would in my opinion be most undesirable for a trial limited to the issue of liability to take place.
62 In Pioneer Park Pty Limited (supra), the circumstance that a witness was to give evidence critical to both the issue of liability and the issue of damages resulted on the refusal of the application for a limited trial. In that case Einstein J said at para [7]:
