13 The difference between the parties in relation to the bank guarantee is that Quadrant and Hoff, through the New South Wales proceedings, seeks a declaration that it only needs to provide $2.4 million of new bank guarantees in order to cover HP's claims. In contrast, HP - because it insists the additional sums notified on 11 June are valid claims under the relevant contractual provisions - contends that Quadrant and Hoff must provide new bank guarantees of $7.4 million.
14 Both parties initially contended that they had commenced proceedings first, suggesting this as a consideration in determining the motion to transfer the proceedings. However eventually both parties conceded that this was not a major factor in determining the ultimate issue: cf BHP Billiton Ltd v Schultz (2004) 221 CLR 400 discussed below.
15 As stated above, HP commenced the Victorian proceedings on 7 May 2010.
16 However, Quadrant and Hoff contended the Victorian proceedings had only been served on 20 July 2010.
17 Quadrant and Hoff conceded that it had been aware of the Victorian proceedings before they had been served, but contended that there was no evidence it had been aware before its proceedings were filed in New South Wales.
18 Ultimately, this issue, concerning as it does where proceedings were first commenced, is of little relevance.
19 Quadrant and Hoff conceded that if the motion to transfer failed and its New South Wales proceedings were allowed to proceed, it would not seek damages and thus the suit would be a purely declaratory matter in relation to the bank guarantee issue.
20 As stated above, the parties disagreed as to whether the New South Wales and Victorian proceedings had a subject matter that crossed-over (with HP contending they did and Quadrant and Hoff contending they did not). Quadrant and Hoff's main proposition was that its New South Wales proceedings were confined to the bank guarantee issue, whereas HP's Victorian proceedings constituted a full blown breach of warranty case. Here Quadrant and Hoff contended that the relevant contractual provision for its bank guarantee case did not feature in HP's Victorian proceedings. However, as I understood it, Quadrant and Hoff conceded that in determining the bank guarantee case it would be necessary to determine which of HP's claims were valid under the relevant contractual provisions. HP drew on this factor, contending that this was a substantial overlap between the proceedings.
21 In my view there is real substance in the submission of HP that both the New South Wales and Victorian proceedings inherently require determination of the validity of HP's claims under the relevant contractual provisions. Therefore, as HP contended, there is a major and unavoidable overlap between the two sets of proceedings. An examination of the relevant pleadings shows this to be true. For example, Quadrant and Hoff, in its summons, in summary claims a declaration that the additional amounts claimed by HP on 11 June 2010 are not valid contractual claims, such that Quadrant and Hoff is correct as to the amount of the replacement bank guarantee that it must provide. Similarly, HP in the Victorian proceedings pleads a breach of warranty case and it is a prerequisite to establishing such a case that the claim is permitted under the contractual regime.
