15 Mr Corsaro of Senior Counsel, who appeared with Mr Doyle of counsel for Mr Assafiri, submitted that on its proper construction clause 16.3(a)(iii), read in conjunction with clause 1.1(h), entitled Mr Assafiri to costs on the indemnity basis. I am not sure that that submission is correct. In any event, and again seeking as best I can to respect the parties' bargain, I think that the appropriate course is to order that costs payable be calculated in accordance with the formula set out in clause 1.1(h). I appreciate that this may cause some problems of assessment. However, the definition is clear in its terms, and the discretionary factors to which regard must be paid in deciding whether a particular item of expense is reasonable are equally clear. It would be open to the parties to put before an assessor (if they cannot agree) such material as might be relevant to inform a determination of the question of reasonableness.
16 In any event, as I have indicated, it is always open to the parties to agree. If they cannot do so, and if it is thought that the process of assessment might be extremely difficult and expensive, it is open to the parties to apply for a gross sum order.
17 Mr Corsaro relied, in the alternative, on what he submitted was "relevant delinquency" on the part of Shell (the phrase comes from the judgment of Gaudron and Gummow JJ in Oshlack v Richmond River Council (1998) 193 CLR 72 at 89). Mr Corsaro submitted, at some length, that Shell's conduct of the proceedings exhibited relevant delinquency having regard to my findings. He submitted that Shell, properly advised, should have understood that there was no factual foundation for its defence (see the judgment of Woodward J in Fountain Selected Meats (Sales) Pty Ltd v International Produce Merchants Pty Ltd (1988) 81 ALR 397 at 401).
18 I do not think that this is an appropriate case for indemnity costs on what I might call the "Oshlack" basis. True it is that I made various findings about Shell's conduct, and its motivations, that were less than favourable. But the submissions put by Mr Corsaro, if accepted, would mean that in almost every case the unsuccessful party, as it were retrospectively informed by the reasons of the Court, should be taken to have known that it could not successfully prosecute or defend the case (as the case may be), so as to render it liable for indemnity costs. I do not think that this is an approach to be encouraged.
19 Again, it is necessary to bear in mind that Mr Assafiri pursued issues that in my view were unsustainable. For example, I disagreed with the case that he ran on "highest and best use" and "basement as an aspect of highest and best use". Again, I rejected his claim for damages for loss of the contract of sale of the subject land. An order for indemnity costs would mean, among other things, that Shell would be bound to pay all of Mr Assafiri's costs even though part of them were on any view referable to claims that were, and that properly advised he should have realised were, unsustainable.
20 Shell does not ask for any order for costs other than the usual one. It takes that stand recognising that it succeeded on some issues and lost on others. That is appropriate. But it does not mean that the question of success and failure on particular issues is not relevant to the issue of indemnity costs.
21 As I have said, I do not think that the claim for indemnity costs on the Oshlack basis has been made good.
22 The remaining issue which separates the parties is the question of interest on costs. As a general rule, a successful party who is held entitled to its costs is entitled to interest on those costs in the usual way. It is not correct to say that an order for interest on costs should be made only in an exceptional or unusual case. That was made clear by Campbell J in Lahoud v Lahoud [2006] NSWSC 126 at [82] and [83]. See also Brereton J in Hexiva Pty Ltd v Lederer [2006] NSWSC 1259 at [21]. Einstein J reviewed and summarised the relevant principles in Liberty Grove (Concord) Pty Ltd v Mirvac Projects Pty Ltd [2008] NSWSC 216. I accept, and adopt, his Honour's summary at [21]:
[21] There are cannot be any serious issue is to the principles. They include the following:
i. it is not necessary for the Court to be satisfied that the circumstances of the case are out of the ordinary before interest on costs is awarded: Australian Development Corp Pty Ltd v White Constructions (ACT) Pty Ltd (in liq) [2002] NSWSC 280 at [23] per Einstein J;
ii. the principal rationale underpinning an order for payment of interest on costs is to compensate the successful litigant for having relevantly been out-of-pocket from having arranged payment of legal costs to its legal representatives during the course of lengthy proceedings: see ADC v White (supra) at [17].
iii. the overriding principle is to provide the successful litigant with full justice and compensation for delay: Barclays Australia (Finance) Ltd v GWG Leviny Pty Ltd (unreported, Supreme Court of New South Wales, Rolfe J, 10 December 1998);
iv. to the extent to which the plaintiffs have been out-of-pocket as a result of having to pay their lawyers' costs and disbursements, it is appropriate that the compensation which is recognised in the Court's order for costs take into account the fact that the plaintiffs have been out-of-pocket in that way: Hughes Bros v The Trustees of the Roman Catholic Church for the Archdiocese of Sydney [1999] NSWSC 1051 at [60] per Foster AJ;
v. relevant matters to consider are the amount of costs paid and the length of time the claimant has been out-of-pocket before recovery: Grogan v Thiess Contractors Pty Ltd [2000] NSWSC 1101 at [11] per Barr J;
vi. it is also relevant where, as here, both parties conduct businesses, that the moneys which the plaintiffs have had to pay is likely to be money which otherwise could have been put to a productive use.
vii. conversely, the defendants, by not being required to pay costs until some time in the future when the costs are agreed or assessed, are likely to have been able to retain, for their own productive use, the amount of those costs: Lahoud v Lahoud [2006] NSWSC 126 at [83] per Campbell J;
viii. the true position is that the ordering of interest on costs will be appropriate (absent disentitling conduct) where the discretion is properly enlivened: here that is seen to be the case as the applicant has been relevantly out-of-pocket from having arranged to pay legal costs from time-to-time during the course of lengthy litigation in which the applicant ultimately succeeded and where the respondent may be presumed to have benefited from not having had to pay the costs at the time when they were paid to the applicant's legal representatives, hence having had the use of the money from that time: see ADC v White (supra) at [28] per Einstein J.
