The discount to be applied
23 In relation to the second issue, where actual or indemnity costs are adopted as a basis for estimating costs, the discount factor becomes central. Previous decisions which apply various discounts are of little use. The discount must vary to ensure that the estimate of actual or indemnity costs is appropriately reduced to such a level that it bears some relationship to the party-party costs which would be recoverable on taxation. To put it bluntly, the more expensive the lawyers, the larger the discount. The Respondents submit that the appropriate discount is two-thirds. Norcast submits that it is 45% (Norcast further discounts its 45% figure by two-thirds, that issue is dealt with below).
24 It is not the purpose of security to give a full indemnity to the Respondents: see, eg, Brundza v Robbie & Co (No 2) (1952) 88 CLR 171 at 175 per Fullagar J. Further, in Bryan E Fencott and Associates Pty Ltd v Eretta Pty Ltd (1987) 16 FCR 497, French J stated at 515 that "the process of estimation embodies to a considerable extent, necessary reliance on the 'feel' of the case after considering relevant factors" (citations omitted). In Save the Ridge Inc v Commonwealth of Australia [2004] FCA 1289, Emmett J was of the view at [24] that "[i]n assessing quantum of an order for costs, a broad brush approach needs to be taken". Bearing Fullagar J's comments in mind, after consideration of the "feel" of the case and adopting a broad brush approach, I consider that the Respondents' are entitled to 50% of their estimated actual or indemnity costs as an estimate of their party-party costs allowable on taxation.
25 Related to the second issue is the function of the so called "two-thirds rule". The nomenclature is perhaps confusing. The Respondents have used two-thirds as their discounting factor. Norcast submits that, whatever figure is arrived at as the appropriate estimate of party-party costs, that figure must be further discounted by two-thirds. In support of that proposition, Norcast relies upon the comments of Lindgren J in Allstate at 197 that the "two-thirds rule" is the "generally observed practice in England of ordering security in an amount equal to two-thirds of the amount of party/party costs". Allstate is not an endorsement of the blanket application of the "two-thirds rule" in this jurisdiction. Indeed, Heerey J in Farmitalia at 345 considered that such a rule had "no justification in law or logic". In Allstate, Lindgren J ultimately applied the two-thirds rule to some applicants, but not to others. His Honour did refer, however, to Quad Consulting Pty Ltd v David R Bleakley and Associates Pty Ltd [1991] FCA 288 as "a helpful review of the conventional fixing of the amount of security at two-thirds of the estimated amount of party/party costs".
26 In Quad Consulting Burchett J considered an application for security for costs which followed an earlier application which was dismissed by Beaumont J. His Honour considered the origins and application of the "two-thirds rule" in Australia. His Honour was referred to Procon (Great Britain) Ltd v Provincial Building Co Ltd (1984) 2 All ER 368 in which Cumming-Bruce LJ considered at 376 that:
the principle is this: the security should be such as the court thinks in all the circumstances of the case is just. If security is sought, as it often is, at a very early stage in the proceedings, the court ordering security will be faced with a situation in which a solicitor or his clerk has made an estimate of the costs likely in the future to be incurred; and probably the costs already incurred, or paid, will be a very small fraction of the security that the applicant is seeking. At that stage one of the features of the future of the action which is relevant is the possibility that the action may be settled, perhaps quite soon. In such a situation it may well be sensible to make an arbitrary discount of costs estimated as the probable future costs, but whether one-third is likely in any given case to be a sensible discount, and whether any discount at all should be made, will depend on the view of the court on consideration of all the circumstances.
27 Having considered Procon, and other authorities, Burchett J held at [10] that:
it remains open to the court to apply a discount of about two-thirds, not because it is a conventional figure to deduct, but because in all the circumstances of the particular case such a discount seems appropriate. In many cases, judges have done so, and this is the origin of the practice which was held in Procon to have been too rigidly stated. The discount may be seen to be appropriate particularly in cases where the chances of settlement, or the possibility that substantial amounts may be taxed off the bill, or the prospect or actuality of off-setting costs orders, may provide a tangible basis for reducing the amount proposed. In making a reduction, apart from some specific matter, the court will bear in mind the view accepted by Fullagar J that the object is not to set out to give a complete and certain indemnity, but to order security to be given "of a reasonable amount". In Menhaden, Toohey J, expressly basing himself on what Fullagar J had said in Brundza, ordered security in the sum of $12,000 in respect of costs estimated at $20,000. That, of course, was less than two-thirds, but Toohey J commented that the estimate had seemed high.
(Emphasis added.)
28 In summary, the "two-thirds rule" may be applied where there are factors present which suggest that the quantum of the security ought to be further discounted. Those factors include the chances of settlement, the merits of the case, whether an order of security would effectively deny the applicant from pursuing the claim, the strength of the evidence regarding the quantification of the security, the possibility that substantial amounts may be taxed off the bill and the prospect or actuality of off-setting costs orders: Quad Consulting at [10]; Farmitalia at 345. Subsequent cases have indicated that the discount to be applied is not fixed at two-thirds, but may vary as circumstances dictate: see, eg, Pathway Investments at [55].
29 Norcast, in seeking to apply the "two-thirds rule", does not refer to any of those factors. While Norcast does refer to the prospects of settlement, it does so as a justification for restricting the steps included in the security to only those costs incurred up to and including the preparation of evidence (see [30] to [33] below). Accordingly, there is no basis for a further discount of two-thirds (or some other fraction) in this case to account for the prospects of settlement.
