(a ) Interest
3 I found that each of AAH, AT and Mr Heydon was liable in damages to the NRMA for $21,193,828 plus interest. Interest had to be calculated. The interest was interest to be included in the sum for which judgment is given pursuant to s 94 of the Supreme Court Act 1970.
4 The NRMA claimed interest calculated to 3 June 1999 at $10,539,412 and continuing at $5,414.04 per day. The defendants agreed with the calculation as a calculation, but raised three issues.
5 First, AAH submitted that interest should not run between 10 June 1997 and 25 May 1998. If that were so, the corresponding figures were agreed as a calculation at $8,472,615 and $5,414.04. Secondly, AT submitted that there should be additional interest on a component of the damages. If that were so, the corresponding figures were agreed as a calculation at $10,655,461 and $5,544.14. Thirdly, Mr Heydon submitted that interest should not run for the last eleven months to judgment. If that were so, the corresponding figures (treating 13 May 1999 as judgment) were agreed as a calculation at $8,658,781 and $5,414.04. The effect of the second issue could be cumulative on the effect of the first or third issues, but the first and third issues were alternatives. It was not suggested that judgment after 13 May 1999 would affect the calculation for the third issue.
6 The first and third issues were different manifestations of the same argument, that the NRMA should not have interest referable to what was said to be a period of delay occasioned by its late joinder of Mr Heydon as a defendant.
7 The NRMA brought the proceedings in late 1995. It joined only AAH and AT as defendants. On 11 September 1996 the proceedings were fixed for hearing to commence on 9 June 1997. On 15 May 1997 that hearing was vacated, amongst other reasons because the NRMA said that it was considering joining Mr Heydon as a defendant. The NRMA decided to join Mr Heydon as a defendant, and leave to join him was given on 20 June 1997. On 25 July 1997 the proceedings were fixed for hearing to commence on 2 February 1998. On 7 August 1997 that hearing was vacated and the proceedings were fixed for hearing to commence on 25 May 1998, the change being for reasons of counsels' availability.
8 There were, of course, directions hearings with a view to the preparation of the proceedings for hearing, initially for the hearing to commence on 9 June 1997 and then, with the additional involvement of Mr Heydon, for the hearing to commence on 25 May 1998. AAH and AT did not comply with the directions given for service of witness statements prior to the hearing to commence on 9 June 1997. They served substantial witness statements of Messrs Morgan, Simpson and Bateman and Mrs Castle at the end of April 1997. One of the NRMA's contentions on 15 May 1997 was that, because of the need to interview potential witnesses and respond to the witness statements, there was insufficient time for the NRMA properly to prepare its case for the hearing.
9 The witness statements included proposed evidence from Messrs Morgan, Bateman, Simpson and Mrs Castle of communications with Mr Heydon in relation to describing the shares as free shares and the significance of Gambotto's case to the proposal. The other of the NRMA's contentions on 15 May 1997 was to the effect that it had not until then been in a position responsibly to join Mr Heydon as a defendant, that it was communicating with Mr Heydon's solicitors with a view to Mr Heydon providing a statement, and that subject to what might come from that communication it thought it could then properly make the allegations in due course made against Mr Heydon.
10 For these reasons the NRMA proposed on 15 May 1997 that the hearing to commence on 9 June 1997 be vacated. It is possible that, with a late start some time at the end of June 1997, the hearing could have been retained notwithstanding the difficulty in which the NRMA had been put by the defaults of AAH and AT. But it had been put in a difficult position, and was likely to suffer prejudice. Mr Heydon submitted before me that the NRMA had been in possession of sufficient information, via particulars and discovered documents, to enable it to decide whether or not to join him no later than August or September 1996, but I consider that the direct (proposed) evidence of Messrs Morgan, Simpson and Bateman and Mrs Castle was an important matter in deciding whether or not to make the allegations in due course made against Mr Heydon.
11 I was the judge principally involved in the directions hearings, and the judge who vacated the hearing to commence on 9 June 1997. The looming prejudice to the NRMA and the need to have settled the position of Mr Heydon in my view gave good grounds for vacating the hearing, and I do not think that the loss of the hearing to commence on 7 June 1997 was due to default, delay, or unreasonable attention to the proceedings or its claims on the part of the NRMA. The occasion for changing the refixed hearing from 2 February 1998 to 25 May 1998 was certainly no fault of the NRMA, but rather against its wishes.
12 Interest is awarded in the exercise of the discretionary power in s 94 of the Supreme Court Act 1970. The power is to be exercised in order to provide compensation, not to punish, and on the basis that the defendant has had the benefit of not paying the capital sum and the plaintiff has had the detriment of not having it: Bennett v Jones (1977) 2 NSWLR 355 at 367-70. Delay occasioned by a plaintiff, while relevant, does not mean no interest during the period of delay, and some particular economic disadvantage occasioned by the delay and material to the exercise of the discretion must be shown; ibid; Perri v Flavell (No 2) (NSWCA, 20 September 1995, unreported).
13 In the present case there was no evidence of particular economic disadvantage, and none was suggested in submissions. AAH and Mr Heydon relied only on asserted delay by the NRMA (AT did not take up either of these issues).
14 If there were to be an exercise of the discretion by excluding a period from the time for which interest is to run, in principle the exclusion should be of the last eleven months to judgment. The proper manifestation of the argument was as the third issue, rather than the first issue, on the basis that, but for the asserted delay, judgment would have been given eleven months earlier. But I do not think that there should be any break in the running of interest.
15 Even assuming in favour of AAH and Mr Heydon that the NRMA acted unreasonably in failing initially to join Mr Heydon as a defendant, that is, that the NRMA had information warranting his joinder from a time in the latter part of 1996 and could and should have joined him then, I do not think that the proper exercise of the discretion calls for such a result. But I do not think that the NRMA acted unreasonably in that respect, and in any event the hearing to commence on 9 June 1997 was compromised by the defaults of AAH and AT. On the principles earlier stated, and in the circumstances in which the vacation of the hearing came about and the eleven months "delay" occurred, I do not think sufficient reason has been shown to decline to award interest for the period in question or any part of it.
16 The second issue was rather curious. The NRMA had not paid some of AT's fees for its legal services in connection with the proposed demutualisation. Its claim included the amount in question, $256,392, and so it recognised a liability to AT. AT argued that when it was paid the $256,392 it was entitled to receive interest of $116,049 on that sum, apparently as some equivalent to s 94 interest and not as a contractual entitlement. So, AT said, the NRMA's damages should include additional interest of $116,049.
17 Interest of $116,049 payable to AT would not be s 94 interest to be included in the sum for which judgment is given. If to be included in that sum, it would be as a capital item in the damages. The NRMA did not claim it. There was no cross-claim by AT to recover the $256,392. Payment of the $256,392 by the NRMA to AT is not part of these proceedings, and the additional interest of $116,049 should not be awarded.
18 The interest calculated to the date of these reasons is $10,875,082, and the sum for which judgment should be given including that interest is $32,068,910.
