The Parties' submissions
24 In written submissions, the applicants contended that the Tribunal erred by:
(a) deciding the Offer was sufficiently certain to qualify as a Calderbank offer or otherwise support an order for indemnity costs;
(b) deciding the applicants had in fact achieved an outcome that was less than the amount of the Offer;
(c) failing to consider whether the applicants' rejection of the Offer was unreasonable at the time it was made, and refusing to take into account all matters relevant to that question; and
(d) failing to determine that it was not unreasonable for the applicants to reject the Offer at the time it was made.
25 It is worth noting, however, that the gravamen of the applicants' attack on the Tribunal's reliance on the Offer in the Federal Court proceedings to justify an award of indemnity costs in the Tribunal proceedings was contained in the following two paragraphs of their written submissions:
In this case, the Offer relied on by the Commonwealth involved the settlement of all the claims made by the Applicants against each of the respondents in the Federal Court proceedings, including the Applicants' claims for damages for infringement of moral rights, interest pursuant to statute, and a public apology pursuant to s 195AZA of the [Copyright] Act … .
As those claims were not before the Tribunal, and had not been assessed at the time of the Tribunal's decision, in making its decision on costs the Tribunal was not in a position to determine whether the outcome achieved by the Applicants was in fact less favourable than the terms of the Offer. Accordingly, the Applicants contend the Tribunal ought to have decided that the Offer was not sufficiently certain to qualify as a Calderbank offer and disregarded the effect of the Offer on the question of costs. Cf Management 3 Group Pty Ltd v Lenny's Commercial Kitchens Pty Ltd (No 3) (2011) 278 ALR 754 at [26]-[37].
26 The applicants emphasised that there was "no basis for the Tribunal to conclude the parties had agreed on the quantum of the moral right claims at the time of the Offer or subsequently".
27 The applicants relied on similar considerations to support their contention that the Tribunal erred in determining that, having regard to the terms fixed by the Tribunal for the use of the applicants' copyright and the objective value of the applicants' moral rights claims, they had obtained an outcome that did not exceed the amount of the Offer. The applicants' submission was that the Tribunal could not in law be so satisfied because "such a determination had to be based on the actual value of the Applicants' claims, rather than an estimate". As this actual value had not been determined at that time by the Federal Court, then, so the applicants submitted, the Tribunal could not be satisfied that the applicants had not obtained an outcome that exceeded the Offer.
28 In reply submissions, the applicants submitted that the Tribunal's decision that the Offer was sufficiently certain to qualify as a Calderbank offer, notwithstanding that it included the resolution of claims which had yet to be heard and determined by the Federal Court, involved the Tribunal proceeding on the basis of a misconception as to the existence of an agreement between the parties on the value to be attributed to the applicants' moral rights claims at the time the Offer was made; and that for this reason the decision involved the Tribunal exercising its discretion to award costs on the basis of a wrong principle, and was therefore a decision that the Tribunal was not authorised to make for the purposes of s 5(1)(c) and (d) of the ADJR Act. Because the Tribunal proceeded on the basis of an estimate of the moral rights claims, the applicants submitted that the decision involved an error of law or was otherwise contrary to law within the meaning of s 5(1)(f) and (j) of the ADJR Act, citing Avon Downs Pty Ltd v Federal Commissioner of Taxation (1949) 78 CLR 353 at 360.
29 The applicants also argued that the Tribunal erred by failing to consider whether it was unreasonable for them to reject that offer at the time it was made, and by failing to take into account various matters that properly bore on that assessment, including the uncertainty of the Offer, the deferred payment terms to which it was subject, the admitted solvency risks surrounding Radiowise and Mr Rubinstein, the stage at which the Offer was made and the applicants' understanding of the strengths and weaknesses of their case at the time the Offer was made. As the applicants said, the Offer was made early in the Federal Court proceedings, before any evidence was filed in those proceedings (or in the Tribunal proceedings), and before the parties had exchanged legal argument in support of their respective positions.
30 The applicants submitted that the Tribunal's failure to apply the correct reasonableness test, and to take into account all of the considerations relevant to the question of reasonableness, meant that the making of the decision involved an error of law or was otherwise contrary to law for the purposes of s 5(1)(f) and (j) of the ADJR Act, and was an improper exercise of the power conferred by s 174(1) of the Copyright Act within the meaning of ss 5(1)(e) and 5(2)(b) of the ADJR Act.
31 In written submissions, the Commonwealth submitted that the offer was sufficiently certain to support an order for indemnity costs in the Tribunal. It submitted that the Offer clearly attributed $50,000 to legal costs, rather than offering an "all-in" amount for the claim and costs. The Commonwealth submitted that "the Offer was clear and capable of being understood by the Applicants at the time they rejected it" and that "the Offer could also be clearly compared by the Tribunal against the Applicants' net monetary result from the litigation as a whole".
32 The Commonwealth contended that it was open to the Tribunal to find that there was sufficient agreement as to the value of the moral rights claim in light of the Commonwealth's statement that "the Commonwealth agrees with the position stated in the Applicants' solicitor's letter of 9 July 2014 that the value of the moral rights claim is 'in the order of $20,000 to $30,000', but would not exceed that range." It also argued that the Tribunal had considered the reasonableness of the applicants' rejection of the offer; and that their rejection of the offer was unreasonable. In particular, the Commonwealth submitted that "the key facts … were either known to the Applicants (the value of their licence to the Brisbane City Council) or matters of public record (the fact that Brisbane represents about one twentieth of Australia's population);" and "[t]his was not a case where the true nature of the case would remain unknown to the Applicants until discovery of documents or cross-examination at trial".
33 At the hearing, Mr Heerey, who appeared for the Commonwealth, submitted that the Tribunal's decision as to costs was within the wide discretion conferred by s 174 of the Copyright Act. Mr Heerey argued that the application made to the Tribunal under s 183 of the Copyright Act, to fix terms appropriate to compensate the applicants for the use of the synchronisation right in the Song by the Commonwealth, was effectively part and parcel of the determination of issues raised in the Federal Court proceedings. In support of this submission, Mr Heerey characterised the applicants' letter of 8 August 2013, to which we have already referred, as "probably the most relevant letter in the whole case" because it was written by the applicants' solicitors while the Offer was still open to be accepted. We have already described the content of this letter, which Mr Heerey relied on in support of the proposition that "[t]he Tribunal proceeding is a necessary subset of the Federal Court proceeding, given that that's where the section 183 issue first arose". Since the Tribunal proceeding was, in his submission, properly characterised as a subset of the Federal Court proceedings, then it was open to the Tribunal to rely on the rejection of the Offer, to found an award of indemnity costs, and, having regard to the Offer and the Tribunal's decision under s 183(5), to conclude that the applicants would have achieved a more favourable outcome had they accepted the Offer.
34 In this way, Mr Heerey sought to distinguish the decision of the High Court in Stewart (in his capacity as liquidator of Newtronics Pty Ltd (in liq)) v Atco Controls Pty Ltd (ACN 005 182 481) (in liq) (No 2) (2014) 252 CLR 331 and the decision of a Full Court of this Court in PTTEP Australasia (Ashmore Cartier) Pty Ltd v Commissioner of Taxation (No 2) [2014] FCAFC 96, which the Court drew to both parties' attention at the commencement of the hearing.
35 Mr Heerey also emphasised the broad discretion as to costs that had been conferred on the Tribunal and, referring to Oshlack v Richmond River Council (1998) 193 CLR 72 at [31], submitted that the applicants were bound to show that the decision was "definitely extraneous to any objects the legislature could have had in view" in enacting s 174 of the Copyright Act. Mr Heerey accepted, however, that if the Tribunal had in fact applied a wrong principle in making the costs decision, then the appropriate course was to remit the matter to the Tribunal for re-consideration, under s 16(1)(b) of the ADJR Act.
36 After hearing Mr Heerey, the Court invited Mr Ryan SC, who appeared with Mr Rebikoff for the applicants, to limit his oral submissions to the question whether or not, if the applicants' challenge were upheld, the appropriate course would be to remit the matter to the Tribunal for further consideration. Referring to Minister for Immigration and Ethnic Affairs v Conyngham (1986) 11 FCR 528, Mr Ryan submitted that the matter should not be remitted and instead that this Court should award costs in favour of the applicants. This was on the basis that, in effect, there would be no residual discretion to be exercised by the Tribunal on the question of costs as the only course open to the Tribunal would be to order that the applicants pay the Commonwealth's costs of the Tribunal proceeding on the ordinary basis.
