3.3 What order as to costs should be made?
22 In my view, subject to certain qualifications, it is reasonable and fair in all of the circumstances for the applicant to pay 70 per cent only of the Commissioner's costs excluding any costs incurred by the Commissioner in the preparation of amended written submissions after the hearing and the costs of the hearing on 4 December 2015.
23 In reaching this view, I have had regard to a number of considerations.
24 First, the starting point is that the ordinary rule as to costs should apply, absent special circumstances.
25 Secondly, while the Commissioner was substantially successful to the extent that 70 per cent of the relevant amount was held to be taxable, the applicant was also successful in reducing the amount of taxable income earned through the provision of the Indian Services by 30 per cent. In these circumstances it is not appropriate in my view to award the Commissioner all of his costs but only a proportion of his costs which broadly reflects the extent of his ultimate success in terms of the amount of taxable income vis a vis the applicant.
26 Thirdly, it was not in dispute that the bulk of the evidence led by the applicant related to the Article 12 royalty issue on which the applicant was largely unsuccessful. Otherwise the evidence was primarily directed towards establishing the income earned by the provision of the Australian and Indian Services respectively, with the Commissioner accepting the applicant's calculations in his Objection Decision and in Tech Mahindra (No 1). I accept in this regard, the Commissioner's submission that these factors tell against any order requiring the Commissioner to pay any proportion of the applicant's costs. I also note that the applicant's alternative suggestion that the Commissioner pay 25 per cent of the applicant's costs was still likely to lead to a result whereby the Commissioner effectively received no compensation for his costs and quite possibly would pay more to the applicant in costs than he would receive.
27 In this regard, it is difficult with respect to give much weight to the applicant's submission that its costs were disproportionately greater than those incurred by the Commissioner because the onus lay upon it to prove its case and therefore a further order should be made that the Commissioner should pay part of the applicant's costs. It is true that the evidence led by the applicant was extensive and required considerable analysis, and that two of the three witnesses for the applicant, together with the applicant itself, were resident in India, no doubt adding significantly to the costs. However, that evidence was in the applicant's possession and not the Commissioner's, and was led by the applicant in order to discharge its onus under s 14ZZO(b)(i) of the TAA to prove that the assessment was excessive. The applicant's position in this regard is no different from that of any other applicant challenging an assessment under Part IVC of the TAA.
28 On the other hand, I consider that the Commissioner should be required to pay the applicant's costs thrown away as a result of the late raising of the treaty architecture argument, including all of the costs incurred by the applicant in preparing amended written submissions after the hearing. In this regard, part of the Commissioner's ultimate success is attributable to his success in the treaty architecture argument which, it will be recalled, was put only in the course of oral address after the applicant had put his case in chief in written submissions and orally. This understandably, as I said in Tech Mahindra (No 1) at [47], drew criticism from the applicant, notwithstanding that the argument raised a question of law only. In addition, the fact that the argument was raised only at the hearing meant that there was a need for the parties to amend their written submissions after the hearing. Nor had the treaty architecture argument formed the basis of the decision by the Commissioner on the Objection Decision, which decided the objection in the first instance on the ground that the Indian Services were taxable under Article 7 and only in the alternative under Article 12. In these circumstances, I consider that this is a case where the Commissioner should bear the burden of the applicant's costs which were unnecessarily incurred as a result of the Commissioner's late change in position.
29 However, given that an award of costs is compensatory in the sense that it is intended to indemnify the successful party, I do not accept that the Commissioner's conduct in this regard could support any greater award of costs to the applicant (Oshlack v Richmond River Council (1998) 193 CLR 72 at 89 [44] (Gaudron and Gummow JJ) and 122 [134(6)] (Kirby J); see also ibid at 75 [1] (Brennan CJ) and 97 [67] (McHugh J) (in dissent but not on this point)). I also note that no order for indemnity costs is sought. Further, I do not consider that the applicant's submission that it was thereby deprived of the opportunity of researching and considering the international authorities should sound in some greater award of costs, at least on the material at this stage. While ss 37M and 37N of the Federal Court Act reinforce the requirement for parties to ensure that pleadings give fair notice of their respective positions, the applicant proposed a period of ten days within which to file amended submissions following receipt of the Commissioner's submissions as amended and updated to reflect the new argument, and did not suggest that any longer period was required.
30 In this regard, I have specified that the applicant's costs thrown away include the preparation of the amended submissions after the hearing notwithstanding that the amendments made to the applicant's written submissions were not limited to responding to the treaty architecture argument but included additional references to the small amount of further evidence at trial. In my view it is fair to ensure that the applicant receives the whole of its costs for the amended written submissions as it would have been unnecessary for any amended and updated submissions to be filed after the hearing save for the late raising of the treaty architecture argument. For the same reason, I consider that the Commissioner should not be entitled to any costs for the preparation of his amended and updated written submissions after the trial: Latoudis v Casey (1990) 170 CLR 534 at 565-566 (Toohey J).
31 Finally, I note that the applicant submitted that to make an award in the applicant's favour of costs thrown away by reason of the Commissioner's late treaty architecture argument, as opposed to awarding the applicant a percentage of its costs, would potentially open the door to a complex assessment on the issue of costs. With respect, I am not persuaded that that would be so. The applicant would have put the same arguments on Articles 7 and 12(3) as were made in its original written submissions irrespective of the Commissioner's treaty architecture argument. The late raising of the treaty architecture argument simply added a further issue which the applicant was required to meet. Consistently with this, the applicant identified in oral argument only the amended written submissions, together with work undertaken by the applicant's legal representatives overnight after the issue was raised, as costs wasted by reason of the delay in the argument being raised, albeit that the applicant was endeavouring to illustrate only wasted costs and resources rather than committing itself to an exhaustive list.
