The indemnity principle
17The plaintiffs' first broad complaint in this appeal is that the costs assessor assessed the defendant's solicitors' costs without regard or proper regard to the indemnity principle. I pause to observe that the costs assessor did not in fact assess the costs of the defendant's solicitors. Rather he assessed the party/party costs payable by the plaintiffs to the defendant as a result of the costs orders made in its favour pursuant to s 364 of the Act: see also s 367A.
18An understanding of the indemnity principle requires an appreciation of the distinction between party/party costs and practitioner/client costs.
19Practitioner/client costs are the costs that the practitioner charges the client for the legal services provided: Qantas Airways Ltd v Dillingham Corp (unreported, NSWSC, Rogers J, 14 May 1987) ; Stanley v Phillips (1966) 115 CLR 470 at 478. They are governed by the law of contract, subject to legislative intervention and the inherent supervisory jurisdiction of the Supreme Court: Woolf v Snipe ( 1933) 48 CLR 677; Re Dibbs and Farrell (1941) 41 SR (NSW) 249 at 251; Richfort Pty Ltd v Baluyut (1999) 152.FLR.203 at 205.
20Party/party costs, on the other hand, are the legal costs that one party recovers from another party in litigation as a result of an order of the court. They are, therefore, governed by the court order, and are to be assessed "on the ordinary basis" unless the court orders otherwise: UCPR r 42.2 and r 42.5. The "ordinary basis" means the basis set out in s 364(1) and (2) of the Act: s 3 of the Civil Procedure Act 2005 .
21Party/party costs are in the nature of an indemnity of the party's practitioner/ client costs, although they will rarely amount to a full indemnity of the practitioner/client costs, because, f or example, party/party costs do not include unreasonable or unusual costs: EMI Records Ltd v Ian Cameron Wallace Pty Ltd [1982] 2 All ER 980 . Nor will they include costs incurred by an "unusually fussy, hysterical, ignorant, suspicious and vindictive'' client: Huggard v Huggard (1902) 8 ALR 178 . See also Smith v Smith [1906] VLR 78.
22This indemnity principle means that a party cannot recover from another party more costs than he or she has paid or is liable to pay her or his own legal practitioner: General of Berne Insurance Co v Jardine Reinsurance Management Ltd [1998] 2 All ER 301 at 308. As was submitted for the plaintiffs, party/party costs are compensatory, and are not awarded to punish the losing party: Latoudis v Casey (1990) 170 CLR 534 at 563 and 567. Thus, to award a larger amount in party/party costs to a successful litigant than the amount for which she or he is liable to his or her own lawyer would be to give a profit to the successful litigant, and to penalise the unsuccessful litigant.
23The plaintiffs contend that the costs assessor made an error of law in finding, in the assessment under appeal, that the indemnity principle had not been breached, and in so finding he misapplied or misunderstood the law.
24The defendant contends, on the other hand, that the costs assessor understood the indemnity principle and appropriately applied it.
25It was submitted for the plaintiffs:
"In order to decide whether the indemnity principle has been offended...a costs assessor must have evidence before him to prove what the costs applicant's liability actually is to his solicitor for doing the work for which solicitors' costs are claimed in the party-party itemised Bill."
26It was further submitted that a costs applicant has the onus of proving that it was in fact liable for the costs claimed, and that the actual liability is only attracted when the lawyer renders an invoice in the amount claimed.
27In my view the plaintiffs' submissions are flawed. To the extent that it was asserted that the onus of proof lies in respect of each individual item appearing in a bill of costs, in the context of determining whether the indemnity principle has been offended, is to misconceive the assessment process.
28The assessment of costs is not a taxation on an item-by-item basis: CSR Ltd v Eddy [2008] NSWCA 82 at [4].
29The new costs assessment scheme was introduced by the legislature in the Legal Profession Amendment (Costs Assessment) Act 1998 to replace the old taxation system, with a view to a "faster, easier and cheaper system".
30The new costs assessment scheme is a paper driven, user (loser) pays system. The process is not a proceeding in the court: Brierley v Reeves t/as Kaplan Reeves & Co [2000] NSWSC 305 ; O'Connor v Fitti [2000] NSWSC 540 ; Furber v Gray [2002] NSWSC 1144 ; Flexible Manufacturing Systems Pty Ltd v Alter [2004] NSWSC 29 ; Diemasters Pty Limited v Meadowcorp Pty Ltd (Unreported, NSWSC, Master Macready, 16 July 2003) .
31Thus, the costs assessment process is a statutory process that is neither wholly judicial, nor wholly adversarial, as there are strong elements of an inquisitorial nature involved. These features of the process are important to understand when evaluating decisions as to a matter of law made in the course of the assessment.
32The costs assessor is required to assess the entirety of the costs the subject of the application: Turner v Pride [1999] NSWSC 850 , not each individual item. An application for the assessment of party/party costs is often accompanied by a bill of costs, but this is not a requirement. The regulations require only that certain particulars and other information be provided, sufficient to enable assessment. This includes such details as the relevant work performed, the period over which it was performed, the persons who did the work, including their position or status in the law practice, and the basis on which the costs have been calculated (whether on a lump sum basis, an item of work basis or an hourly rate basis). The facts relied on to justify the costs must be set out together with details as to the skill, labour and responsibility involved, the complexity, novelty or difficulty involved, the quality of the work, or any other relevant matter.
33Nor is it accurate to suggest that the actual liability for practitioner/client costs is only attracted when the lawyer renders an invoice in the amount claimed. That liability arises from the contractual relations between the practitioner and the client: Wentworth v Rogers [2006] NSWCA 145 at [129].
34An invoice, if and when it is rendered, serves to quantify the limit of the liability. In that situation, the amount of the indemnity available is established, and it would of course be wrong to allow to a party an amount of party/party costs that exceeded to the total of the practitioner/client costs charged in any invoice. But how the individual items going to make up the total are made up is irrelevant.
35The particular decision of the costs assessor as to a matter of law asserted on behalf of the plaintiffs is said to arise from the following passage in his Reasons:
"I have perused the costs agreement between the costs applicant and its legal advisers. I am satisfied that the amount claimed by the costs applicant is no greater than the amount for which the costs applicant would be liable pursuant to those agreements...I find the indemnity principle has not been breached."
36The plaintiffs contend that the costs assessor made an error of law in that there was no evidence to support his finding that the indemnity principle was not breached. This was because he had no tax invoices before him to consider.
37Counsel for the defendant submitted that in the absence of an evidentiary foundation for doing so, the costs assessor was not obliged to investigate whether or not the indemnity principle has been offended and was entitled to proceed on the basis that a client who retains a practitioner will be liable to pay that practitioner's fees and charges. Thus it was incorrect for the plaintiffs to submit that that a costs assessor must have evidence before him to prove what a costs applicant's actual liability is to his practitioner.
38My attention was drawn to Wentworth v Rogers [2006] NSWCA 145 and a more recent decision of the Victorian Court of Appeal in Shaw v Yarranova Pty Ltd [2011] VSCA 55. It was submitted that these decisions are authority for the proposition that in the absence of a proper evidentiary basis for doing so, a party should not be required to produce tax invoices or other documents, either to establish the clients' liability to pay costs to their solicitors, or to establish the actual costs paid (emphasis added), so as to establish a liability to pay costs to their solicitors in amounts at least as great as the amounts claimed as party/party costs. In other words, proof of the existence of a retainer for the provision of legal services, whether by direct evidence, or implied from their conduct, gives rise to a presumption that the retainer is based on a contract for the provision of legal services for a fee: Shaw v Yarranova Pty Ltd [2011] VSCA 55 at [17] and [27]:
"Once it is recognised that it will ordinarily be presumed in the case of a solicitor who acts on the record for a party that there is a retainer and that the party for whom the solicitor acts is liable for the solicitor's costs...there was nothing before the Costs Judge that made it likely that any of the material sought by the applicant would advance the contention that the indemnity principle had been displaced. The evidence did not raise the likelihood that the costs that had been paid or were to be paid were less than those that had been taxed. Beach J correctly concluded that the applicant was on a 'fishing expedition'..."
39The flaw in the defendant's submission is that in the present assessment there was credible evidence before the costs assessor that did in fact raise the likelihood that the costs for which the defendant was liable to its solicitors were less than those that had been claimed by it in the bill of costs submitted to the costs assessor in support of the application for assessment.
40First, the evidence before the costs assessor clearly established that tax invoices were rendered to the defendant by its solicitors.
41This was not a case, for example, where there was a conditional costs agreement pursuant to which the costs to be charged by the solicitor were to be the costs actually recovered on a party/party basis, such that no invoices had as yet been rendered. The fact that there were invoices set the limit for the amount the defendant might recover on a party/party basis. There was no evidence before the costs assessor as to what that limit was.
42Secondly, and importantly in the context of this assessment, was the evidence that put the costs assessor on clear notice that the plaintiffs were alleging that certain work was performed Mrs Deigan, and was performed at times when her practising certificate had been suspended, or at a time when she was employed by the client itself, and not by the solicitor.
43The effect of this material, in my view, was to raise a serious question as to whether the defendant's liability for practitioner costs was less than the amount claimed in the bill of costs submitted to the costs assessor, thus displacing any presumption. I do not consider that he was required to investigate each individual item or to examine who performed each item of work claimed in the bill of costs. What he should have done, however, was to ensure that the total amount claimed for professional work in the bill of costs did not exceed the total amount charged in the invoices. His failure to do so resulted in a misapplication, in the assessment, of the indemnity principle. In my view, that failure amounted to an erroneous decision as to a matter of law arising in the proceedings to determine the application for assessment.
44Having decided this question concerning the indemnity principle, the appeal is partly allowed and I do not propose to affirm the costs assessor's decision as to this matter of law. I must therefore now proceed under s 384(2) of the Act and determine whether I should make such determination in relation to the application as, in my opinion, should have been made by the costs assessor, or remit the decision on the question to the costs assessor and order the him to re-determine the application. I will invite the parties to make submissions on this question.
