Question 2: should the costs be determined on an issue-by-issue basis as between each of the Applicants and Glass Candy?
17 Glass Candy submitted that a successful party's costs might be reduced by reference to discrete issues on which the party had failed and, indeed, that the successful party might in some circumstances be ordered to pay the costs of a discrete issue upon which it was unsuccessful. The costs discretion is unfettered but the following themes may be extracted from the authorities:
18 First, the general rule is that costs follow the event.
19 Secondly, the general rule may be departed from and a successful party may (a) be prevented from recovering all of its costs in relation to an issue on which it failed; or, (b) be ordered to pay the costs in relation to an issue on which it failed. If the question of who won the litigation is contestable then this may warrant a consideration on an issue-by-issue basis. But where it is not, there are 'good reasons not to encourage applications regarding costs on an issue-by-issue basis, involving apportionments based on degrees of difficulty of issues, time taken to argue them and the like': Firebird Global Master Fund II Ltd v Republic of Nauru (No 2) [2015] HCA 53; 90 ALJR 270 at [6] per French CJ, Kiefel, Nettle and Gordon JJ. Even where the question of who won the litigation is contestable, there may be practical reasons militating against approaching the matter on an issue-by-issue basis. For example, whilst it may be possible to separate the legal issues it may be that the factual substratum on which those issues rest is common to more than one issue: Les Laboratoires Servier v Apotex Pty Ltd [2016] FCAFC 27; 247 FCR 61 ('Les Laboratoires Servier') at [300] per Bennett, Besanko and Beach JJ.
20 So too, a court may take into account, but is not bound to, that awarding costs on an issue-by-issue basis may encourage parties to consider carefully what matters they will put in issue: Les Laboratoires Servier at [301]. The empirical evidence for this thought experiment, however, is thin. Whilst it is tempting to think that the economic incentive not to incur irrecoverable costs on failed issues should exert a disciplining effect on parties and their advisers about the issues they select to run, a number of practical matters conspire to reduce any such effect. The first of these is that any costs consequence is far off in the future and costs are not usually taxed before the end of a proceeding. The natural human tendency is to underestimate the future cost of present conduct, as anyone who has been to a decent dinner party will attest. Secondly, for the suggested economic incentive to be effective it would need to be understood by the parties (and their advisers) that there was a real risk that the general rule would be departed from and the exception engaged. However, the general rule is not called the general rule for nothing and it is therefore rational for parties (and their advisers) to think that there will be no costs penalty for losing on particular issues because, generally, it is the fact that there will not be. This naturally encourages a mindset in which issues proliferate because of a sense that, so long as one wins, it will not matter and, if one is going to lose, well, it is going to be a full-blown disaster anyway so one may as well hang the expense. For the economic incentive actually to exert influence on decision-making it would be necessary for it to be understood as the general rule, rather than as the exception to that rule. The present litigation is a good example of how little effect this supposed encouragement towards issue-parsimony has in real litigation. It involved sophisticated parties who were well represented but even so there was no issue which was too sickly not to have its day in court.
21 Thirdly, there is an interest for all parties in the costs hearing not descending into a re-run of the trial: Lockwood Security Products Pty Ltd v Doric Products Pty Ltd (No 2) [2007] FCAFC 172 at [8]-[9] per Heerey, Sundberg and Bennett JJ. That was said, of course, in the context of patent litigation where sometimes different considerations may be at play, but nevertheless it is, with respect, a sound observation. To that may be added two further observations: (a) hearing complex issue-by-issue costs argument diverts limited judicial resources from the central task of hearing trials; (b) once an issue-by-issue approach is taken it makes more complex the task of taxation.
22 I do not think it would be appropriate to separate out the issues as between the Applicants and Glass Candy. Both sides had some significant wins and some significant losses. The Applicants succeeded in showing that Glass Candy deliberately copied the sung lyric 'love is in the air' from Love. This was a large factual undertaking and was hard fought. In a sense, although it was far from the only issue in the case, it was one of the central questions. On the other hand, the Applicants certainly suffered some serious setbacks in the course of securing this victory. They failed to show that the copyright in the literary work had been infringed. In relation to the musical work, it is true that they succeeded in showing that the line 'love is in the air' in Warm was objectively similar to 'H1' but they failed in relation to 'H2' or 'H3' about which there was both plenty of expert evidence and plenty of disputation (H1, H2 and H3 were slightly different variants of the sung lyric in Love: see [80] and following of the Liability Judgment). The Applicants lost the moral rights claim although it must be said not because the Court was not satisfied that Love had not been subject to derogatory treatment within the meaning of s 195AI(2) of the Act but only because that provision did not apply in Montreal and Portland where the derogation took place: s 195AX. But it was still a loss. Glass Candy stressed that it defeated Boomerang by proving that it did not own the copyright in Love which is true. But it was a victory secured only at the price of proving that the copyright in Love was owned by APRA and AMCOS. Viewed from a little distance, this kind of victory appears to be a net neutral result.
23 It is also true, as Glass Candy correctly submits, that the case in relation to streaming from music services (such as iTunes) failed because the streaming services held relevant APRA and AMCOS licences. But the Applicants did succeed in relation to the Big Cartel website and the full consequences of that outcome are yet to be seen. Further, in reality Glass Candy let Kobalt have the principal running on that issue and largely (although I accept not altogether) adopted its submissions about it.
24 Glass Candy also raised some other points on the issue-by-issue question but they were less material than the ones to which I have just referred. I am cognisant of these other matters but they seemed tangential and minor.
25 This is a case where the question of who, if anyone, won is quite contestable and it would be open to me to approach the matter on an issue-by-issue approach. However, I do not propose to do so. Picking over the corpse of the trial to perform such an analysis would require much guesswork on my part and there are clearly overlapping issues. For example, I am less than confident of my ability to disentangle the labours that went into the Big Cartel download issue from those which went into the streaming service issues. Further, I am not confident that my impression of how much sitting time was taken at trial on particular issues necessarily fairly reflects the time which was actually spent on those issues by the parties. For example, whilst it is true Glass Candy tended to let Kobalt have the running on the streaming issues it is apparent that Glass Candy had looked at those issues from its own perspective and made additional submissions about them. It is quite possible that Glass Candy's decision to let Kobalt have the principal running on the issue was, in fact, just a sensible use of court time. I am not confident therefore that an issue-by-issue analysis would result in an outcome which was fair.
