Interest
14It is not in contest that each plaintiff is entitled to an order for interest on the verdict sum. What is disputed is the manner in, and the rate at, which that interest ought to be calculated. The plaintiffs claim that interest ought to be calculated at the rate of 3.5 per cent per annum. The defendants contend that the appropriate rate is 2 per cent per annum.
15The principles upon which interest is awarded in respect of an award of damages for defamation were stated by McHugh JA in John Fairfax & Sons Ltd v Kelly (1987) 8 NSWLR 131, and adopted in Australian Consolidated Press v Driscoll (1988) Aust Torts Reports 80-175. (Both decisions need some modification to accommodate the later decision of the High Court in MBP (SA) Pty Ltd v Gogic [1991] HCA 3; 171 CLR 657, but that does not affect the approach in principle.) In Gogic , in respect of damages for non-economic loss (not confined to defamation cases), an interest rate of 4 per cent per annum was fixed. Interest is awarded from the date on which the damage is sustained.
16The principle underlying the award of interest seems to be this: where damage is sustained at the time of the commission of the tort (or, presumably, other wrong), interest is calculated at a prescribed or selected rate and multiplied out over the number of years between that date and date of verdict. However, where the damage is of an accumulating, accruing or ongoing kind (for example, pain and suffering in a personal injury case), an apportionment is made so that a plaintiff does not receive interest on damages during a period when the damage had not been suffered. To date the award of interest from the date the cause of action arose, in circumstances where the injury was ongoing, would be to award interest on part of the verdict before the damage for which it was awarded was suffered.
17In theory, that would require a stepped approach to the award of interest. That is plainly an unsuitable way to proceed, and, instead, the interest rate is adjusted.
18Commonly, the adjustment is made by halving the rate. This implies that the damage has been assessed as accruing at a steady rate from the date when the injury was suffered. Where it can be seen that the damage has in fact accrued more recently, it would be appropriate further to reduce the interest rate; where it can be seen that the bulk of the damage was suffered nearer to the date the cause of action arose, the interest rate may be higher.
19In the Court of Appeal both Kelly and Driscoll distinguished between that part of the award of damages for defamation that represented vindication of reputation, and that part that represented consolation for injured feelings. Implicit in these cases is the notion that damage to reputation occurs (and is complete) at the time of publication; injury to feelings accrues and accumulates with the passage of time. That would suggest a bifurcated approach to the question of interest.
20Two circumstances that differentiate each of these cases from the present must be borne in mind. Kelly and Driscoll were both concerned with verdicts following jury trial; and each concerned a single publication. The significance of the first of these circumstances is that the jury award does not dissect the verdict into the quantum awarded for vindication of reputation, and that awarded for injured feelings. Just how much of the award of damages represented damage to reputation, and how much injury to feelings, could not be known (if, indeed, the jury treated the two separately). Here, although the calculation of damages was made by judge alone, and I did not in the judgment embark upon that break up, it is not impossible now, if it is appropriate, to do so.
21The second circumstance (that Kelly and Driscoll involved single publications) is relevant because here, the dates of publication - ie the dates that the injury was sustained - are staggered. Theoretically, it would be possible to calculate interest from the date of each individual publication. However, that would be cumbersome and, in my opinion, overly pedantic.
22Just why it is assumed, in a defamation case, that the entire damage to reputation occurs at the date of publication, but that injury to feelings is ongoing, is not clear to me. But that is how the Court of Appeal has applied the law relating to interest in defamation cases; and, unless there is an evidentiary basis to do otherwise, I must follow that approach. A contrary view received some support from the judgment of McColl JA in Channel Seven Sydney Pty Ltd v Mahommed [2010] NSWCA 335. The assumption is one that can be displaced in order to fit in with the known facts.
23It may be that the approaches taken in Kelly and Driscoll have been, to some extent, overtaken. In Mahommed , McColl JA, with whom Spigelman CJ, Beazley JA, McClellan CJ at CL and Bergin CJ in Eq agreed, quoted from McClellan CJ at CL in Greig v WIN Television NSW Pty Ltd [2009] NSWSC 877 where his Honour said:
"[i]t is commonly accepted that the primary damage to a plaintiff's reputation and injury to feelings is occasioned at the time of publication and shortly thereafter",
placing emphasis on the word "primary". Her Honour went on to point out that in each case the assessment of damages must be made with reference to the facts peculiar to each case. Her Honour somewhat diluted the concept that injury to reputation occurs (and is complete) at the time of publication, but that injury to feelings accrues. Her Honour pointed out that injury to reputation may accumulate in circumstances where belief in the sting of imputations becomes more entrenched or the number of the plaintiff's acquaintances who are aware of the imputations increases. To this I would add that a relevant circumstance is the nature of the publication. Where, for example, the publication is in book form, there may be new readers over months and years. That can be contrasted with publication by electronic media which, at least until the advent of the internet, was usually transitory, in which case it may be more likely that the bulk of the damage caused to reputation was caused at or close to the time of publication. This conclusion has implications for the manner in which interest is calculated.
24As I have said above, it is also relevant that the award of damages is that of myself, and not a jury. I am able, if appropriate, to dissect the award into that allowed for damage to reputation, and that for injury to feelings.
25The other complicating circumstance in this case is that the publications that gave rise to the damages were sequential, from March 1998 to September 2003. No party paid any attention to the question of the commencement date of the award of interest. Clearly, it would be an injustice to the defendants to order commencement from the date of the first publication. It would, equally be an injustice to the plaintiffs to defer it until the date of the last publication. No party suggested that the interest question ought to be decided individually in relation to the damages awarded in respect of each separate publication and I do not propose to do so. However, successive publication is a relevant consideration in the overall determination.
26There is another consequence of the sequential publication of the newsletters, relevant to the presumption that, in defamation, the damage to reputation is suffered and is complete at the time of publication. In the unusual circumstances of this case, that assumption cannot comfortably be made. That is because each publication was likely to reinforce those which preceded it, particularly where, as often happened, there was repetition of the defamatory material and/or of the defamatory imputations (for example, a recurring theme was the imputation that Mr Megna was dishonest and/or incompetent).
27That would tell in favour of a reduced rather than higher interest rate, since the more severe damage has occurred at a later date.
28On behalf of the plaintiffs a global solution was proposed, based upon the further (reasonable) assumption that, in respect of each plaintiff, the damages awarded were evenly divided between those awarded for vindication of reputation and those awarded for solace for hurt and distress. That would mean, on Kelly and Driscoll principles, that interest on the 50 per cent awarded for reputation vindication was at 4 per cent from date of publication (just what date should be selected was not adverted to - to achieve this would, presumably, require hypothesising a date of publication at the mid-point between March 1998 and September 2003); and interest on the 50 per cent awarded for injury to feelings at 2 per cent (from the same hypothetical date). That would produce an average interest rate of 3 per cent. Senior counsel for the plaintiff stated, in written submissions:
"10. Interest at the rate of 3 per cent has often been awarded"
but identified no case in which that had occurred. He went on to argue for an interest rate of 3 per cent, attributing the additional per cent to the length of time that has elapsed since publication. The reasoning behind that submission was not spelled out.
29Notwithstanding some unusual features, I am satisfied that no sufficient basis has been exposed for departing from the approach taken in Gogic . Countervailing circumstances tend each way, and ought to be balanced against one another.
30I propose to take a notional publication date for all publications of the mid-point between the dates of publication of the first and last and to award interest on the whole of the damages at 2 per cent from that date. A convenient date to begin is 1 January 2001.
31It will be necessary for the parties to calculate the figure that results.
